- OBJECTIVETo evaluate the chronicity of polypharmacy among older adults and to identify factors associated with chronic polypharmacy.DESIGNLongitudinal cohort study using register data.SETTINGNationwide, Sweden.PARTICIPANTSAll 711,432 older adults (aged 65 years and older) living in Sweden with five or more prescription drugs in October 2010 were included and followed up until December 2013. Mean age at baseline was 77 (SD = 7.8) years, 59% were women, and 7% lived in nursing homes.MEASUREMENTMonthly changes in the exposure to polypharmacy. Data regarding prescription drug use were extracted from the Swedish Prescribed Drugs Register.RESULTSOverall, 82% were continuously exposed to polypharmacy for 6 months or longer, and 74% for 12 months or longer. The proportion of individuals who remained exposed until the end of the study was 55%. Among the 21,361 individuals who had not been exposed to polypharmacy during the 6-month period before baseline (ie, with a new episode of polypharmacy), only 30% remained exposed for 6 months or longer. The proportion of older adults who spent at least 80% of their follow-up time with polypharmacy was substantially higher among prevalent polypharmacy users at baseline than among those with a new polypharmacy episode (80% vs 24%; P < .01). Factors associated with chronic polypharmacy included higher age, female sex, living in an institution, chronic multimorbidity, and multidose dispensing.CONCLUSIONPolypharmacy is most often chronic, although a substantial share of older adults experience short, recurring episodes of polypharmacy and are thus exposed to its potential harms in a transient rather than persistent manner.

- OBJECTIVES: To examine job control, job demands, social support at work, and job strain (ratio of demands to control) in relation to risk of any dementia, Alzheimer's disease (AD), and vascular dementia (VaD). DESIGN: Cohort study. SETTING: The population-based Study of Dementia in Swedish Twins. PARTICIPANTS: Two hundred fifty-seven people with dementia (167 AD, 46 VaD) and 9,849 without. MEASUREMENTS: Dementia diagnoses were based on telephone screening for cognitive impairment followed by in-person clinical examination. An established job exposure matrix was matched to main occupation categories to measure work characteristics. RESULTS: In generalized estimating equations (adjusted for the inclusion of complete twin pairs), lower job control was associated with greater risk of any dementia (odds ratio (OR) = 1.17, 95% confidence interval (CI) = 1.04-1.31) and VaD specifically (OR = 1.39, 95% CI = 1.07-1.81). Lower social support at work was associated with greater risk of dementia (OR = 1.15, 95% CI = 1.03-1.28), AD (OR = 1.14, 95% CI = 1.00-1.31), and VaD (OR = 1.28, 95% CI = 1.02-1.60). Greater job strain was associated with greater risk of VaD only (OR = 1.28, 95% CI = 1.02-1.60), especially in combination with low social support (OR = 1.35, 95% CI = 1.11-1.64). Age, sex, and education were controlled for. Work complexity, manual work, and vascular disease did not explain the results. No differences in work-related stress scores were observed in the 54 twin pairs discordant for dementia, although only two pairs included a twin with VaD. CONCLUSION: Work-related stress, including low job control and low social support at work, may increase the risk of dementia, particularly VaD. Modification to work environment, including attention to social context and provision of meaningful roles for employees, may contribute to efforts to promote cognitive health.

- OBJECTIVE: To investigate the effects of 10 weeks of progressive vigorous-intensity interval training as a single intervention on body composition among 70-year-old individuals with central obesity.DESIGN: Randomized controlled trial (ClinicalTrials.gov registration No. NCT03450655).SETTING: Community-dwelling 70-year-old men and women living in the Umeå municipality in Sweden.PARTICIPANTS: Seventy-seven 70-year-old men and women with central obesity (greater than 1 kg visceral adipose tissue [VAT] for women and greater than 2 kg VAT for men).INTERVENTION: Participants allocated to the intervention group were offered a 10-week progressive concurrent exercise program performed three times per week. All participants in both groups had received tailored lifestyle recommendations focused on diet and physical activity at one occasion within 12 months prior to trial initiation.MEASUREMENTS: The primary outcome was changes in VAT, and secondary outcomes included changes in total fat mass (FM), total lean body mass (LBM), and body mass index.RESULTS: Comparing the groups, there were no significant differences in decrease of VAT mass (P = .10), although the intervention group significantly decreased FM by 716 g (P = .01) and gained LBM by 508 g (P = .03), compared to the control group. Furthermore, the effects of the training were significantly greater in the male subcohort (P < .05 for interaction), with positive effects also on VAT and FM, where men in the intervention group decreased VAT by 175 g (P < .05) and FM by 1364 g (P = .004), compared to the male controls.CONCLUSIONS: The present trial demonstrates that 10 weeks of progressive vigorous interval training is sufficient to significantly decrease FM in older adults with central obesity, with positive effects also on LBM.

- OBJECTIVES: To evaluate the association between number of days with delirium and 6-month mortality in elderly adults after hip fracture surgery. DESIGN: Prospective cohort study with 6-month follow-up. SETTING: Orthogeriatric Unit (OGU). PARTICIPANTS: Individuals (mean age = 84.3 +/- 6.4) admitted to the OGU between October 2011 and April 2013 with hip fracture (N = 199). MEASUREMENTS: Postoperative delirium (POD) was assessed daily using the Confusion Assessment Method algorithm and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, criteria. Multivariable Cox regression models were used to evaluate the association between POD of and 6-month mortality after surgery, after adjustment for covariates including age, prefracture residence, Katz activity of daily living score, New Mobility score, diagnosis of prefracture dementia, American Society of Anesthesiologists score, albumin serum levels, Charlson Comorbidity Index, and length of OGU stay. RESULTS: Fifty-seven participants (28.6%) developed POD. In the 6-month period after surgery, 35 (17.6%) participants died: 16 of 57 (28.1%) with POD and 19 / of 142 (13.4%) with no POD. The average duration of POD was 2.0 +/- 3.2 days for participants who died and 0.7 +/- 1.8 days for those who survived (P < .001). After adjusting for covariates, each day of POD in the OGU increased the hazard of dying at 6 months by 17% (hazard ratio = 1.17, 95% confidence interval = 1.07-1.28). CONCLUSION: In older adults undergoing hip fracture surgery, duration of POD is an important prognostic factor for 6-month mortality. Efforts to reduce duration of POD are therefore crucial for these individuals.

- OBJECTIVES: To assess the safety and efficacy of teriparatide in patients aged 75 and older and compare these findings with those of women younger than 75 using data from the Fracture Prevention Trial (FPT). DESIGN: The FPT was a randomized, multicenter, double-blind, placebo-controlled study. SETTING: The FPT multicenter international study. PARTICIPANTS: Postmenopausal women aged 42 to 86 were randomized to placebo (N=544) or teriparatide 20 mug (N=541) by daily self-injection for a median of 19 months. Patients received daily oral supplements of 1,000 mg calcium and 400 to 1,200 IU vitamin D. For this analysis, subgroups were defined according to patient age younger than 75 (N=841) and 75 and older (N=244). MEASUREMENTS: The effects of teriparatide on bone mineral density (BMD) of the lumbar spine and femoral neck; the incidence of new vertebral and new nonvertebral fragility fractures; bone turnover markers, including bone-specific alkaline phosphatase; and urinary deoxypyridinoline corrected for creatinine clearance, as well as the safety of teriparatide, were investigated. RESULTS: There were no significant treatment-by-age interactions for the bone turnover markers, femoral neck BMD, vertebral fractures, nonvertebral fragility fractures, height loss, hyperuricemia, or hypercalcemia. A significant treatment-by-age interaction for lumbar spine BMD (P=.08) was due to an increase in BMD observed in the placebo group aged 75 and older. There were no treatment-by-age interactions for important treatment-emergent adverse events (TEAEs), including back pain, nausea, leg cramps, and dizziness. The most important TEAEs in women aged 80 and older (23 patients from the placebo group and 25 patients from the teriparatide group) were also reviewed; no unexpected TEAEs were found in the patients treated with teriparatide. These results indicate that the clinical effects of teriparatide were consistent in the older and younger women. CONCLUSION: Age does not affect the safety and efficacy of teriparatide in postmenopausal women with osteoporosis.

- Counterpoised against dire projections of the tripling of the prevalence of dementia over the next 40 years are major developments in diagnostic biomarkers, neuroimaging, the molecular biology of Alzheimer's disease (AD), epidemiology of risk and protective factors, and drug treatments—mainly targeting the amyloid pathway, tau protein, and immunotherapy—that may have the potential to modify the progression of AD. Drug combinations and presymptomatic treatments are also being investigated. Previous trials of dementia-modifying drugs have not shown benefit, and even if current Phase III trials prove successful, these drugs will not eradicate other dementias, could (if not curative) increase dementia duration and prevalence, and are unlikely to come onto the market before 2020. In the meantime, delaying the onset of dementia by even 2 years would have significant economic and societal effects. This article provides an overview of current achievements and potentials of basic and clinical research that might affect the development of dementia prevalence and care within the near future.

- OBJECTIVES: To investigate the association between low vitamin D levels (<50 nmol/L) and 10-year mortality in women aged 75 and older.DESIGN: Prospective with 15 years of follow-up.SETTING: Malmö, Sweden.PARTICIPANTS: Population-based cohort of 75-year-old women (N = 1,044).MEASUREMENTS: Serum 25-hydroxyvitamin D (25(OH)D) levels at age 75 (n = 1,011), 80 (n = 642), and 85 (n = 348) were categorized as low (<50 nmol/L), intermediate (50-75 nmol/L) and high (>75 nmol/L) at all ages. Hazard ratios (HRs) for all-cause mortality between ages 75 and 90 were calculated according to 25(OH)D category.RESULTS: Between ages 80 and 90, all-cause mortality (HR = 1.8, 95% confidence interval (CI) = 1.3-2.4, P < .001; adjusted for comorbidities (aHR) = 1.9, 95% CI = 1.4-2.6, P < .001) was significantly higher in women with low 25(OH)D levels than in those with high levels. Osteoporosis had the greatest effect on mortality, but even after excluding women with osteoporotic fracture during the risk of dying associated with low 25(OH)D remained greater (HR = 1.8, 95% CI = 1.2-2.7, P = .002; aHR = 1.7, 95% CI = 1.2-2.5, P = .006).CONCLUSION: In this observational study of women aged 75 and older, 25(OH)D levels of less than 50 nmol/L were associated with greater all-cause mortality for up to 10 years. This difference was at least partially independent of comorbidities and fracture, indicating that low 25(OH)D not only is an indicator of impaired health, but also plays a role in disease outcome.

Tidskriftsartikel (refereegranskat)abstract
- Background: Little is known about changes in gastrointestinal symptoms compatible with disorders of gut-brain interaction (DGBI) with increasing age at the population level. The objective of this study was to describe the patterns of DGBI in individuals 65 years of age and above and contrasting them with those of younger adults.Methods: A community sample of 6300 individuals ages 18 and older in the US, UK, and Canada completed an online survey. Quota-based sampling was used to ensure equal proportion of sex and age groups (40% aged 18-39, 40% aged 40-64, 20% aged 65+) across countries, and to control education distributions. The survey included the Rome IV Diagnostic Questionnaire for DGBI, demographic questions, questionnaires measuring overall somatic symptom severity and quality of life, and questions on healthcare utilization, medications, and surgical history.Results: We included 5926 individuals in our analyses; 4700 were 18-64 years of age and 1226 were ages 65+. Symptoms compatible with at least one DGBI were less prevalent in participants ages 65+ vs. ages 18-64 years (34.1% vs. 41.3%, p < 0.0001). For symptoms compatible with upper GI DGBI, lower prevalence for most disorders was noted in the 65+ group. For lower GI DGBI, a different pattern was seen. Prevalence was lower in ages 65+ for irritable bowel syndrome and anorectal pain, but no differences from younger participants for the disorders defined by abnormal bowel habits (constipation and/or diarrhea) were seen. Fecal incontinence was the only DGBI that was more common in ages 65+. Having a DGBI was associated with reduced quality of life, more severe non-GI somatic symptoms, and increased healthcare seeking, both in younger and older participants.Conclusion: Symptoms compatible with DGBI are common, but most of these decrease in older adults at the population level, with the exception of fecal incontinence which increases. This pattern needs to be taken into account when planning GI health care for the growing population of older adults.

- OBJECTIVES Analyses performed by the Sarcopenia Definitions and Outcomes Consortium (SDOC) identified cut-points in several metrics of grip strength for consideration in a definition of sarcopenia. We describe the associations between the SDOC-identified metrics of low grip strength (absolute or standardized to body size/composition); low dual-energy x-ray absorptiometry (DXA) lean mass as previously defined in the literature (appendicular lean mass [ALM]/ht(2)); and slowness (walking speed <.8 m/s) with subsequent adverse outcomes (falls, hip fractures, mobility limitation, and mortality). DESIGN Individual-level, sex-stratified pooled analysis. We calculated odds ratios (ORs) or hazard ratios (HRs) for incident falls, mobility limitation, hip fractures, and mortality. Follow-up time ranged from 1 year for falls to 8.8 +/- 2.3 years for mortality. SETTING Eight prospective observational cohort studies. PARTICIPANTS A total of 13,421 community-dwelling men and 4,828 community-dwelling women. MEASUREMENTS Grip strength by hand dynamometry, gait speed, and lean mass by DXA. RESULTS Low grip strength (absolute or standardized to body size/composition) was associated with incident outcomes, usually independently of slowness, in both men and women. ORs and HRs generally ranged from 1.2 to 3.0 for those below vs above the cut-point. DXA lean mass was not consistently associated with these outcomes. When considered together, those who had both muscle weakness by absolute grip strength (<35.5 kg in men and <20 kg in women) and slowness were consistently more likely to have a fall, hip fracture, mobility limitation, or die than those without either slowness or muscle weakness. CONCLUSION Older men and women with both muscle weakness and slowness have a higher likelihood of adverse health outcomes. These results support the inclusion of grip strength and walking speed as components in a summary definition of sarcopenia.

- OBJECTIVES: To examine vitamin D status and its association with physical performance and muscle mass in older Chinese men. DESIGN: Cross-sectional and prospective cohort study design. SETTING: Hong Kong, People's of Republic of China. PARTICIPANTS: Nine hundred thirty-nine community-dwelling men aged 65 and older for cross-sectional analysis and 714 for longitudinal analysis. MEASUREMENTS: Baseline serum 25-hydroxyvitamin D (25OHD) was measured using a competitive radioimmunoassay kit. Baseline and 4-year physical performance measures (grip strength, 6-m walking speed, step length in a 6-m walk, time to complete five chair stands) were measured, and appendicular skeletal muscle mass (ASM) was assessed using dual-energy X-ray absorptiometry. Data were collected for confounding factors: demographic, number of diseases, smoking, alcohol use, body mass index, physical activity, diet, season of blood sampling, and serum parathyroid hormone (PTH) level. Multivariate regression analyses were performed with adjustments for confounding factors. RESULTS: Mean±standard deviation serum 25OHD level of this sample of Chinese community-dwelling older men who had a high level of baseline physical function was 77.9±20.5nmol/L; 94.1% of participants had serum 25OHD levels of 50nmol/L or greater. Median (interquartile range) serum PTH level was 4.1pmol/L (3.1-5.5pmol/L). After adjustment for potential confounding factors, serum 25OHD levels were not associated with baseline or 4-year change in physical performance measures and ASM. CONCLUSION: In Chinese older men who are vitamin D replete and have a high level of baseline physical function, vitamin D may not have an important role in physical function and muscle mass.

- Objectives To examine how body mass index (BMI) and change in BMI are associated with mortality in old (7079) and very old (80) individuals. Design Pooled data from three multidisciplinary prospective population-based studies: OCTO-twin, Gender, and NONA. Setting Sweden. Participants Eight hundred eighty-two individuals aged 70 to 95. Measurements BMI was calculated from measured height and weight as kg/m2. Information about survival status and time of death was obtained from the Swedish Civil Registration System. Results Mortality hazard was 20% lower for the overweight group than the normalunderweight group (relative risk (RR)=0.80, P=.011), and the mortality hazard for the obese group did not differ significantly from that of the normalunderweight group (RR=0.93, P=.603), independent of age, education, and multimorbidity. Furthermore, mortality hazard was 65% higher for the BMI loss group than for the BMI stable group (RR=1.65, P<.001) and 53% higher for the BMI gain group than for the BMI stable group (RR=1.53, P=.001). Age moderated the BMI change differences. That is, the higher mortality risks associated with BMI loss and gain were less severe in very old age. Conclusion Old persons who were overweight had a lower mortality risk than old persons who were of normal weight, even after controlling for weight change and multimorbidity. Persons who increased or decreased in BMI had a greater mortality risk than those who had a stable BMI, particularly those aged 70 to 79. This study lends further support to the belief that the World Health Organization guidelines for BMI are overly restrictive in old age.

- OBJECTIVES: To describe the association between body mass index (BMI) and dementia risk in older persons.DESIGN: Prospective population‐based study, with 8 years of follow‐up.SETTING: The municipality of Lieto, Finland, 1990/91 and 1998/99.PARTICIPANTS: Six hundred five men and women without dementia aged 65 to 92 at baseline (mean age 70.8).MEASUREMENTS: Weight and height were measured at baseline and at the 8‐year follow‐up. Dementia was clinically assessed according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria.RESULTS: Eighty‐six persons were diagnosed with dementia. Cox regression analyses, adjusted for age, sex, education, cardiovascular diseases, smoking, and alcohol use, indicated that, for each unit increase in BMI score, the risk of dementia decreased 8% (hazard ratio (HR)=0.92, 95% confidence interval (CI)=0.87–0.97). This association remained significant when individuals who developed dementia early during the first 4 years of follow‐up were excluded from the analyses (HR=0.93, 95% CI=0.86–0.99). Women with high BMI scores had a lower dementia risk (HR=0.90, 95% CI=0.84–0.96). Men with high BMI scores also tended to have a lower dementia risk, although the association did not reach significance (HR=0.95, 95% CI=0.84–1.07).CONCLUSION: Older persons with higher BMI scores have less dementia risk than their counterparts with lower BMI scores. High BMI scores in late life should not necessarily be considered to be a risk factor for dementia.

- To investigate the long-term effects of habitual physical activity on changes in musculoskeletal health, functional performance, and fracture risk in elderly men and women. Ten-year prospective population-based study. Malmo-Sjobo Prospective Study, Sweden. Participants were 152 men and 206 women aged 50, 60, 70, and 80 who were followed for 10 years. Distal radius bone mineral density (BMD) (single photon absorptiometry), upper limb muscle (grip) strength, balance, gait velocity, occupational and leisure-time activity, and fractures (interview-administered questionnaire) were reassessed after 10 years. Annual changes for all measures were compared between participants with varying habitual physical activity histories at baseline and follow-up: inactive-inactive (n=202), active-inactive (n=47), inactive-active (n=49), and active-active (n=60). Data for men and women were pooled, because there were no sex-by-activity group interactions. To detect possible differences in fracture incidence between the varying habitual activity groups, participants were classified into two activity groups based on their activity classification at baseline and follow-up: inactive:less active versus active:more active. The annual rate of bone loss was 0.6% per year less in individuals classified as active at both time points than in those classified as inactive at both time points (P <.01). Similar results were observed for balance, but there was no effect of varying habitual activity on changes in muscle strength or gait velocity. There were also no differences in fracture incidence between individuals categorized as active:more active and those categorized as inactive:less active during the follow-up (adjusted hazard ratio=0.90, 95% confidence interval (CI)=0.42-1.90). This study showed that elderly men and women who maintained a habitually active lifestyle over 10 years had lower bone loss and retained better balance than those who remained habitually inactive.

- OBJECTIVES To examine the effects of various risk factors on three functional outcomes during rehabilitation. SETTING Geriatric inpatient rehabilitation unit. DESIGN Observational longitudinal study. PARTICIPANTS One hundred sixty-one geriatric rehabilitation inpatients (men, women), mean age 82, who were capable of walking at baseline. MEASUREMENTS Functional status was assessed weekly between admission and discharge and at a follow-up 4 months later at home using the function component of the Short Form-Late Life Function and Disability Instrument, the Barthel Index, and Habitual Gait Speed. Various risk factors, such as falls-related self-efficacy (Falls Efficacy Scale-International), were measured. Associations between predictors and functional status at discharge and follow-up were analyzed using linear regression models and bivariate plots. RESULTS Fear of falling predicted functioning across all outcomes except for habitual gait speed at discharge and follow-up. Visual comparison of functional trajectories between subgroups confirmed these findings, with different levels of fear of falling across time in linear plots. Thus, superior ability of this measure to discriminate between functional status at baseline across all outcomes and to discriminate between functional change especially with regard to the performance-based outcome was demonstrated. CONCLUSION Falls-related self-efficacy is the only parameter that significantly predicts rehabilitation outcome at discharge and follow-up across all outcomes. Therefore, it should be routinely assessed in future studies in (geriatric) rehabilitation and considered to be an important treatment goal.

- OBJECTIVES: To determine whether being overweight or obese is associated with significant health outcomes in an 85-year-old population. less thanbrgreater than less thanbrgreater thanDESIGN: A cross-sectional population-based study. less thanbrgreater than less thanbrgreater thanSETTING: Linkoping, Sweden. less thanbrgreater than less thanbrgreater thanPARTICIPANTS: Three hundred thirty-eight people born in 1922 were identified using the local authoritys register. less thanbrgreater than less thanbrgreater thanMEASUREMENTS: Data related to sociodemographic characteristics, health-related quality of life (HRQoL), assistance use, and the presence of diseases were collected using a postal questionnaire. Anthropometry and functional status were assessed during home and geriatric clinic visits. Diseases were double-checked in the electronic medical records, and information about health service consumption was obtained from the local healthcare register. less thanbrgreater than less thanbrgreater thanRESULTS: Overweight (body mass index (BMI) 25.0-29.9 kg/m(2)) and obese (BMI andgt;= 30.0 kg/m(2)) participants perceived more difficulty performing instrumental activities of daily living (IADLs) and had more comorbidity than their normal-weight counterparts (BMI 18.5-24.9 kg/m(2)), but their overall HRQoL and health service costs did not differ from those of normal-weight participants. After controlling for sociodemographic factors, being overweight did not influence IADLs or any comorbidity, but obese participants were more likely to perceive greater difficulty in performing outdoor activities (odds ratio (OR) = 2.1, 95% confidence interval (CI) = 1.1-4) and cleaning (OR = 2.2, 95% CI = 1.2-4.2) than their normal-weight counterparts. Although obesity was also associated with multimorbidity (OR = 3, 95% CI = 1.2-8), the health service cost of each case of multimorbidity (n = 251) was highest in normalweight participants and nearly three times as much as in obese participants (ratio: 2.9, 95% CI = 1.1-8.1). less thanbrgreater than less thanbrgreater thanCONCLUSION: For 85-year-olds, being obese, as opposed to overweight, is associated with self-reported activity limitations and comorbidities. Overweight older adults living in their own homes in this population had well-being similar to that of those with normal weight.

- Background: Olfactory impairment is associated with dementia in clinical settings. We examined the relationship of olfactory identification function with all-cause dementia, Alzheimer's disease (AD), and vascular dementia (VaD) and assessed the discriminative ability of the Sniffin' Sticks Identification Test (SSIT), the self-rated Ascertain Dementia 8-item Questionnaire (AD8), and their combination for dementia detection among rural-dwelling older adults in China.Methods: This population-based cross-sectional study included 4481 participants (age ≥ 65 years; 56.8% women; 38.1% illiteracy) living in rural communities. The 16-item SSIT was performed to assess olfactory identification function. The self-rated AD8 was administered to participants for cognitive status. We diagnosed dementia, AD, and VaD following the international criteria. Data were analyzed with logistic regression models and receiver operating characteristic curve.Results: Of the 4481 participants, dementia was diagnosed in 139 persons (3.1%), including 92 with AD and 42 with VaD. The SSIT score (range, 0–16) was associated with multiadjusted odds ratios of 0.83 (95% CI: 0.79–0.88) for dementia, 0.84 (0.79–0.90) for AD, and 0.79 (0.71–0.87) for VaD. The area under the curve for the discrimination between participants with and without dementia was 0.73 (95% CI: 0.69–0.77) for SSIT score ≤ 8 alone, 0.86 (0.82–0.89) for self-rated AD8 score ≥ 3 alone, and 0.89 (0.86–0.92) for their combination using a logistic model.Conclusions: Olfactory impairment is a clinical marker for all-cause dementia, AD, and VaD. The smell identification test, in combination with the brief self-rated cognitive screening tool, is accurate for screening dementia among rural-dwelling Chinese older adults with no or limited education.

- OBJECTIVES: The aim of this study was to investigate the differences between preoperative and postoperative delirium regarding predisposing, precipitating factors and outcome in older patients admitted to hospital with femoral neck fractures.DESIGN: A prospective clinical assessment of patients treated for femoral neck fractures.SETTING: Department of orthopedic surgery at Umeå University Hospital, Sweden.PARTICIPANTS: One hundred one patients, age 65 and older admitted to the hospital for treatment of femoral neck fractures.MEASUREMENTS: The Organic Brain Syndrome (OBS) Scale.RESULTS: Thirty patients (29.7%) were delirious before surgery and another 19 (18.8%) developed delirium postoperatively. Of those who were delirious preoperatively, all but one remained delirious postoperatively. The majority of those delirious before surgery were demented, had been treated with drugs with anticholinergic properties (mainly neuroleptics), had had previous episodes of delirium, and had fallen indoors. Patients who developed postoperative delirium had perioperative falls in blood pressure and had more postoperative complications such as infections. Male patients were more often delirious both preoperatively and postoperatively. Patients with preoperative delirium were more often discharged to institutional care and had poorer walking ability both on discharge and after 6 months than did patients with postoperative delirium only.CONCLUSIONS: Because preoperative and postoperative delirium are associated with different risk factors it is necessary to devise different strategies for their prevention.

- Objectives: To determine how development of delirium after surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI) could predict activity of daily living (ADL) and instrumental ADLs (IADL) disability, cognitive function, and self-reported health in individuals aged 80 and older.Design: Prospective cohort study. Setting: Tertiary university hospital.Participants: Individuals aged 80 and older undergoing elective SAVR or TAVI (N = 136).Measurements: Delirium was assessed for 5 days using the Confusion Assessment Method. The Barthel Index, Nottingham Extended ADL Scale, and SF-12 were used to determine ADL and IADL ability and self-reported health at baseline and 1- and 6-month follow-up. Cognition was assessed using the Mini-Mental State Examination at baseline and 6-month follow-up.Results: Participants had lower IADL scores 1 month after SAVR than at baseline (baseline 58, 1 month: delirium 42, no delirium 50, P ≤.02), but scores had returned to baseline levels at 6 months. The Medical Outcomes Study 12-item Short-Form Health Survey (SF-12) Physical Component Summary (PCS) score was higher at 6-month follow-up (48) than at baseline (39), especially in participants who did not develop delirium (P <.001). No differences in other outcomes were found. Regression models suggest that delirium may help predict IADL disability 1 month after baseline (P ≤.07) but does not predict large differences in ADL disability, cognitive function, or SF-12-scores. Individuals who underwent TAVI and developed delirium had lower ADL (baseline 19, 1-month 16, P <.001) and IADL (baseline 49, 1-month 40, P =.003) scores at 1-month follow-up. SF-12 PCS score (baseline 30) increased from baseline to 1- (35, P =.04) and 6- (35, P =.02) month follow-up in individuals who underwent TAVI and did not develop delirium. Delirium after TAVI predicted greater ADL and IADL disability at 1-month but not at 6-month follow-up.Conclusion: Individuals who develop delirium after SAVR and TAVI have poorer short-term IADL function but do not seem to have long-term reductions in physical, mental, or self-reported health.

- OBJECTIVES: To identify sex-specific associations between risk factors and injurious falls over the short (<4 years) and long (4-10 years) term.DESIGN: Longitudinal cohort study between 2001 and 2011.SETTING: Swedish National Study on Aging and Care, Kungsholmen, Sweden.PARTICIPANTS: Community-dwelling adults aged 60 and older (N = 3,112).MEASUREMENTS: An injurious fall was defined as a fall that required inpatient or outpatient care. Information was collected on participant and exposure characteristics using structured interviews, clinical examinations, and physical function tests at baseline.RESULTS: The multivariate model showed that, in the short term, living alone (hazard ratio (HR)=1.83, 95% confidence interval (CI)=1.13-2.96), dependency in instrumental activities of daily living (IADLs) (HR=2.59, 95% CI=1.73-3.87), and previous falls (HR=1.71, 95% CI=1.08-2.72) were independently associated with injurious falls in women. Low systolic blood pressure (HR=1.96, 95% CI=1.04-3.71), impaired chair stands (HR=3.00, 95% CI=1.52-5.93), and previous falls (HR=2.81, 95% CI=1.32-5.97) were associated with injurious falls in men. Long-term risk factors were underweight (HR=2.03, 95% CI=1.40-2.95), cognitive impairment (HR=1.49, 95% CI=1.08-2.06), fall-risk increasing drugs (HR=1.67, 95% CI=1.27-2.20 for >= 2 drugs), and IADL dependency (HR=1.58, 95% CI=1.32-5.97) for women and smoking (HR=1.71, 95% CI=1.03-2.84), heart disease (HR=2.20, 95% CI=1.5-3.24), impaired balance (HR=1.68, 95% CI=1.08-2.62), and a previous fall (HR=3.61, 95% CI=1.98-6.61) for men.CONCLUSION: Men and women have different fall risk profiles, and these differences should be considered when developing preventive strategies. Some risk factors were more strongly predictive of injurious falls over shorter than longer periods and vice versa, suggesting that it may be possible to identify older men and women at short-and long-term risk of injurious falls.

- ObjectivesTo determine whether dementia could explain the association between poor olfactory performance and mortality risk within a decade-long follow-up period.DesignProspective cohort study.SettingBetula Study, Umeå, Sweden.ParticipantsA population-based sample of adult participants without dementia at baseline aged 40 to 90 (N = 1,774).MeasurementsOlfactory performance using the Scandinavian Odor-Identification Test (SOIT) and self-reported olfactory function; several social, cognitive, and medical risk factors at baseline; and incident dementia during the following decade.ResultsWithin the 10-year follow-up, 411 of 1,774 (23.2%) participants had died. In a Cox model, the association between higher SOIT score and lower mortality was significant (hazard ratio (HR) = 0.74 per point interval, 95% confidence interval (CI) = 0.71-0.77, P < .001). The effect was attenuated, but remained significant, after controlling for age, sex, education, and health-related and cognitive variables (HR = 0.92, 95% CI = 0.87-0.97, P = .001). The association between SOIT score and mortality was retained after controlling for dementia conversion before death (HR = 0.92, 95% CI = 0.87-0.97, P = .001). Similar results were obtained for self-reported olfactory dysfunction.ConclusionPoor odor identification and poor self-reported olfactory function are associated with greater likelihood of future mortality. Dementia does not attenuate the association between olfactory loss and mortality, suggesting that olfactory loss might mark deteriorating health, irrespective of dementia.

- ObjectivesTo examine the association between tea consumption and depressive symptoms in Chinese older people and to explore the mediating role of cerebrovascular disease in the association. DesignPopulation-based cross-sectional study. SettingA rural community near Qufu in Shandong, China. ParticipantsCommunity-dwelling individuals aged 60 and older (mean 68.6; 59.3% female) from the Confucius Hometown Aging Project (N=1,368). MeasurmentsData were collected through interviews, clinical examinations, and psychological testing, following a standard procedure. Presence of high depressive symptoms was defined as a score of 5 or greater on the 15-item Geriatric Depression Scale. ResultsOf the 1,368 participants, 165 (12.1%) were weekly and 489 (35.7%) were daily tea consumers. Compared with no or irregular tea consumption, controlling for age, sex, education, leisure activities, number of comorbidities, and Mini-Mental State Examination score, the odds ratios of having high depressive symptoms were 0.86 (95% confidence interval (CI)=0.56-1.32) for weekly and 0.59 (95% CI=0.43-0.81) for daily tea consumption (P for linear trend=.001); the linear trend of the association remained statistically significant when further controlling for history of stroke, transient ischemic attacks, and presence of carotid plaques. ConclusionsDaily tea consumption is associated with a lower likelihood of depressive symptoms in Chinese older people living in a rural community. The association appears to be independent of cerebrovascular disease and atherosclerosis.

- OBJECTIVES To investigate the association between nutritional status and general and specific (fluid and crystallized) cognitive functioning in a group of older people living in a rural area in Bangladesh. DESIGN Cross-sectional study. SETTING Matlab, Bangladesh. PARTICIPANTS Four hundred fifty-seven randomly selected persons aged 60 and older (mean age 69.5 +/- 6.8), 55% female. MEASUREMENTS Nutritional status was evaluated using a modified form of the Mini Nutritional Assessment (MNA). General cognitive function was assessed using the Bangla Adaptation of the Mini-Mental State Examination, and a word synonym test was used to test semantic memory function (a crystallized ability). To assess cognitive processing speed (a fluid ability), "cross balls" and "complete boxes" tests (scores/time unit) were used. Clinical diagnoses were registered. Structured questionnaires were used to assess demographic and socioeconomic status of the participants. RESULTS Twenty-six percent of the participants were undernourished, and 62% were at risk of malnutrition according to the MNA. The MNA scores were significantly lower in women than in men (P=.01). Women performed worse than men in all three cognitive tasks (P <.001). Poorer cognitive performance was independently associated with older age, female sex, illiteracy, visual impairment, severity of disease, and depressive symptoms. There were significant associations between better nutritional status and better cognitive performance tests of general ability and processing speed, whereas semantic memory appeared to be less affected. CONCLUSION The association between nutritional status and cognitive function involves general and specific cognitive abilities, with fluid ability seeming to be affected but crystalized functions being relatively spared.

- ObjectivesTo examine relationships between modifiable midlife factors, aging, and physical and cognitive function (independent aging) and survival in very old age. DesignProspective cohort. SettingUppsala Longitudinal Study of Adult Men, Uppsala, Sweden. ParticipantsSwedish men investigated in 1970-74 (aged 48.6-51.1) and followed up for four decades (N=2,293). MeasurementsConventional cardiovascular risk factors, body mass index (BMI), and dietary biomarkers were measured, and a questionnaire was used to gather information on lifestyle variables at age 50. Four hundred seventy-two men were reinvestigated in 2008-09 (aged 84.8-88.9). Independent aging was defined as survival to age 85, Mini-Mental State Examination score of 25 or greater, not living in an institution, independent in personal care and hygiene, able to walk outdoors without personal help, and no diagnosis of dementia. The National Swedish Death Registry provided survival data. ResultsThirty-eight percent of the cohort survived to age 85. Seventy-four percent of the participants in 2008-09 were aging independently. In univariable analyses, high leisure-time physical activity predicted survival but not independent aging. Low work-time physical activity was associated more strongly with independent aging (odds ratio (OR)=1.84, 95% confidence interval (CI)=1.18-2.88) than with survival (OR=1.27, 95% CI=1.05-1.52). In multivariable analyses, midlife BMI was negatively associated (OR=0.80/SD, 95% CI=0.65-0.99/SD), and never or former smoking was positively associated (OR=1.66, 95% CI=1.07-2.59), with independent aging. As expected, conventional cardiovascular and lifestyle risk factors were associated with mortality. ConclusionA normal midlife BMI and not smoking were associated with independent aging close to four decades later, indicating that normal weight at midlife has the potential not only to increase survival, but also to preserve independence with aging.

- OBJECTIVES: To examine the longitudinal associations between aging with preserved functionality, i.e. independent aging and survival, and lifestyle variables, dietary pattern and cardiovascular risk factors.DESIGN: Cohort study.SETTING: Uppsala Longitudinal Study of Adult Men, Sweden.PARTICIPANTS: Swedish men (n = 1,104) at a mean age of 71 (range 69.4-74.1) were investigated, 369 of whom were evaluated for independent aging 16 years later, at a mean age of 87 (range 84.8-88.9).MEASUREMENTS: A questionnaire was used to obtain information on lifestyle, including education, living conditions, and physical activity. Adherence to a Mediterranean-like diet was assessed according to a modified Mediterranean Diet Score derived from 7-day food records. Cardiovascular risk factors were measured. Independent aging at a mean age of 87 was defined as lack of diagnosed dementia, a Mini-Mental State Examination score of 25 or greater, not institutionalized, independence in personal activities of daily living, and ability to walk outdoors alone. Complete survival data at age 85 were obtained from the Swedish Cause of Death Register.RESULTS: Fifty-seven percent of the men survived to age 85, and 75% of the participants at a mean age of 87 displayed independent aging. Independent aging was associated with never smoking (vs current) (odds ratio (OR) = 2.20, 95% confidence interval (CI) = 1.05-4.60) and high (vs low) adherence to a Mediterranean-like diet (OR = 2.69, 95% CI = 1.14-6.80). Normal weight or overweight and waist circumference of 102 cm or less were also associated with independent aging. Similar associations were observed with survival.CONCLUSION: Lifestyle factors such as never smoking, maintaining a healthy diet, and not being obese at age 71 were associated with survival and independent aging at age 85 and older in men.

- ObjectivesThe causes of death in dementia are not established, particularly in rarer dementias. The aim of this study is to calculate risk of death from specific causes for a broader spectrum of dementia diagnoses.DesignCohort study.SettingSwedish Dementia Registry (SveDem), 2007–2012.ParticipantsIndividuals with incident dementia registered in SveDem (N = 28,609); median follow-up 741 days. Observed deaths were 5,368 (19%).MeasurementsInformation on number of deaths and causes of mortality was obtained from death certificates. Odds ratios for the presence of dementia on death certificates were calculated. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox hazards regression for cause-specific mortality, using Alzheimer's dementia (AD) as reference. Hazard ratios for death for each specific cause of death were compared with hazard ratios of death from all causes (P-values from t-tests).ResultsThe most frequent underlying cause of death in this cohort was cardiovascular (37%), followed by dementia (30%). Dementia and cardiovascular causes appeared as main or contributory causes on 63% of certificates, followed by respiratory (26%). Dementia was mentioned less in vascular dementia (VaD; 57%). Compared to AD, cardiovascular mortality was higher in individuals with VaD than in those with AD (HR = 1.82, 95% CI = 1.64–2.02). Respiratory death was higher in individuals with Lewy body dementia (LBD, including Parkinson's disease dementia and dementia with Lewy bodies, HR = 2.16, 95% CI = 1.71–2.71), and the risk of respiratory death was higher than expected from the risk for all-cause mortality. Participants with frontotemporal dementia were more likely to die from external causes of death than those with AD (HR = 2.86, 95% CI = 1.53–5.32).ConclusionDementia is underreported on death certificates as main and contributory causes. Individuals with LBD had a higher risk of respiratory death than those with AD.

- OBJECTIVE: To assess the extent of inappropriateness of drug use in an older nondemented and demented population. DESIGN: Descriptive analysis based on data from a sample of older subjects age 81 years and older. Data were collected from the second follow-up conducted in 1994–1996. SETTING: A population-based study of the Kungsholmen project in Stockholm, Sweden. PARTICIPANTS: Drug information was obtained from 681 subjects with a mean age of 86.9 years. The subjects were predominantly women (78%). Thirteen percent resided in institutions and 27.6% were diagnosed with dementia. MEASUREMENTS: Dementia diagnosis based on DSM III-R. Criteria for inappropriateness of drug use: use of drugs with potent anticholinergic properties, drug duplication, potential drug-drug and drug-disease interactions, and inappropriate drug dosage. RESULTS: The mean number of drugs used was 4.6: 4.5 drugs for nondemented and 4.8 for demented subjects. Nondemented subjects more commonly used cardiovascular-system drugs and demented subjects used nervous-system drugs. Demented subjects were more commonly exposed to drug duplication and to drugs with potent anticholinergic properties, both involving the use of psychotropic drugs. Nondemented subjects were more commonly exposed to potential drug-disease interactions, mostly with the use of cardiovascular drugs. The most common drug combination leading to a potential interaction was the use of digoxin with furosemide, occurring more frequently among nondemented subjects. The most common drug-disease interaction was the use of beta-blockers and calcium antagonists in subjects with congestive heart failure. The doses of drugs taken by both nondemented and demented subjects were mostly lower than the defined daily dose. CONCLUSION: There was substantial exposure to presumptive inappropriateness of drug use in this very old nondemented and demented population. The exposure of demented subjects to psychotropic drugs and nondemented subjects to cardiovascular drugs reflect the high frequency of prescribing these drugs in this population.
