Tidskriftsartikel (refereegranskat)abstract
- Being taller is associated with enhanced longevity, and higher education and earnings. We reanalysed 1472 population-based studies, with measurement of height on more than 18.6 million participants to estimate mean height for people born between 1896 and 1996 in 200 countries. The largest gain in adult height over the past century has occurred in South Korean women and Iranian men, who became 20.2 cm (95% credible interval 17.522.7) and 16.5 cm (13.319.7) taller, respectively. In contrast, there was little change in adult height in some sub-Saharan African countries and in South Asia over the century of analysis. The tallest people over these 100 years are men born in the Netherlands in the last quarter of 20th century, whose average heights surpassed 182.5 cm, and the shortest were women born in Guatemala in 1896 (140.3 cm; 135.8144.8). The height differential between the tallest and shortest populations was 19-20 cm a century ago, and has remained the same for women and increased for men a century later despite substantial changes in the ranking of countries.

Tidskriftsartikel (refereegranskat)abstract
- Sociodemographic factors, such as education and occupation, may influence the individual's cognitive reserve. We explored the extent to which the type and complexity of previous work activities influence cognitive performance (evaluated with Mini-Mental State Examination, MMSE, and the Animal Naming Test, ANT) in 799 older people with or without brain damage. The presence of cortical/subcortical ischemic brain lesions and right/left hippocampal atrophy was derived from magnetic resonance imaging. We found that individuals who had done intellectual work had better MMSE and ANT scores than their counterparts in the presence of brain lesions or hippocampal atrophy. Among the manual workers there were significant differences between the MMSE scores of individuals with and without brain damage (mean MMSE difference (2.09 [SD: 0.68], p=0.01), but not among the intellectuals (0.19 [SD: 0.29], p=0.36) nor the service providers (1.67 [SD: 0.55], p=0.21). Occupations involving more complex dealings with people were associated with better MMSE scores in the presence of brain lesions [β=-0.41, 95%CI: -0.72,-0.09] and hippocampal atrophy [β=-0.29, 95%CI:-0.58,-0.001]. These results indicate that in more cognitively stimulating work with greater social interaction may help older individuals preserve cognitive functions, even in the presence of brain damage.

Tidskriftsartikel (refereegranskat)abstract
- Background Diabetes has been defined on the basis of different biomarkers, including fasting plasma glucose (FPG), 2-h plasma glucose in an oral glucose tolerance test (2hOGTT), and HbA(1c). We assessed the effect of different diagnostic definitions on both the population prevalence of diabetes and the classification of previously undiagnosed individuals as having diabetes versus not having diabetes in a pooled analysis of data from population-based health examination surveys in different regions. Methods We used data from 96 population-based health examination surveys that had measured at least two of the biomarkers used for defining diabetes. Diabetes was defined using HbA(1c) (HbA(1c) >= 6 . 5% or history of diabetes diagnosis or using insulin or oral hypoglycaemic drugs) compared with either FPG only or FPG-or-2hOGTT definitions (FPG >= 7 . 0 mmol/L or 2hOGTT >= 11 . 1 mmol/L or history of diabetes or using insulin or oral hypoglycaemic drugs). We calculated diabetes prevalence, taking into account complex survey design and survey sample weights. We compared the prevalences of diabetes using different definitions graphically and by regression analyses. We calculated sensitivity and specificity of diabetes diagnosis based on HbA1c compared with diagnosis based on glucose among previously undiagnosed individuals (ie, excluding those with history of diabetes or using insulin or oral hypoglycaemic drugs). We calculated sensitivity and specificity in each survey, and then pooled results using a random-effects model. We assessed the sources of heterogeneity of sensitivity by meta-regressions for study characteristics selected a priori. Findings Population prevalence of diabetes based on FPG- or-2hOGTT was correlated with prevalence based on FPG alone (r= 0 . 98), but was higher by 2-6 percentage points at different prevalence levels. Prevalence based on HbA(1c) was lower than prevalence based on FPG in 42 . 8% of age-sex-survey groups and higher in another 41 . 6%; in the other 15 . 6%, the two definitions provided similar prevalence estimates. The variation across studies in the relation between glucose-based and HbA(1c)-based prevalences was partly related to participants' age, followed by natural logarithm of per person gross domestic product, the year of survey, mean BMI, and whether the survey population was national, subnational, or from specific communities. Diabetes defined as HbA(1c) 6 . 5% or more had a pooled sensitivity of 52 . 8% (95% CI 51 . 3-54 . 3%) and a pooled specificity of 99 . 74% (99 . 71-99 . 78%) compared with FPG 7 . 0 mmol/L or more for diagnosing previously undiagnosed participants; sensitivity compared with diabetes defined based on FPG-or-2hOGTT was 30 . 5% (28 . 7-32 . 3%). None of the preselected study-level characteristics explained the heterogeneity in the sensitivity of HbA(1c) versus FPG. Interpretation Different biomarkers and definitions for diabetes can provide different estimates of population prevalence of diabetes, and differentially identify people without previous diagnosis as having diabetes. Using an HbA(1c)-based definition alone in health surveys will not identify a substantial proportion of previously undiagnosed people who would be considered as having diabetes using a glucose-based test.

Forskningsöversikt (refereegranskat)abstract
- Background Polypharmacy is a prevalent condition in older adults, especially those with multiple chronic diseases, and has been largely associated with adverse outcomes, including disability, hospitalizations, and death.Aims This systematic review focused on diabetes and aimed to investigate the prevalence and impact of polypharmacy in older adults affected by such disease.Methods Observational (either cross-sectional or longitudinal) or experimental studies investigating the frequency and impact of polypharmacy in older adults with diabetes were identified from scientific databases and grey literature until August 2021. The prevalence and the 95% Confidence Interval (95% CI) of polypharmacy in older people with diabetes were summarized by a random-effects meta-analysis.Results From a total of 1465 records, 9 were selected for the qualitative synthesis, and 8 for the quantitative synthesis. Most studies defined polypharmacy using a cut-off for the minimum number of medications ranging from 4 to 6 drugs/day. The pooled prevalence of polypharmacy in older people with diabetes was 64% (95% CI 45–80%). Considering studies that used the same definition of polypharmacy (i.e. ≥ 5 drugs/day), the pooled prevalence was 50% (95% CI 37–63%). The between-studies heterogeneity was high. Across the selected studies, polypharmacy seemed to negatively influence both diabetes-specific (poor glycemic control and risk of hypoglycemia) and health-related (risk of incident falls, syncope, hospitalization, and death) outcomes.Conclusion This systematic review confirms the high prevalence of polypharmacy in older people with diabetes and its strong impact on several health-related outcomes, including mortality. These results strengthen the need to improve care strategies for management of these patients.

Tidskriftsartikel (refereegranskat)abstract
- Background: While it is well established that frail older people have a higher risk of negative health outcomes, the prevalence of frailty and its associated factors in Italian older institutionalized population has never been investigated.Aims: The aims of this study were to assess the prevalence of frailty and to identify its associated factors in an Italian residential care home population.Methods: An observational cross-sectional study was designed to evaluate older people aged 70 or over of an Italian residential care home. A multidimensional assessment examining functional, geriatric, ophthalmic, and audiological domains was carried out to identify factors associated with frailty. Physical frailty was evaluated using Fried's criteria.Results: Data analysis uncovered a 51.1% prevalence of pre-frailty and a 40.4% prevalence of frailty in the 94 eligible participants (64 females) whose data were complete. The multivariable analysis showed that a low education level (OR = 5.12, 95% CI 1.22-21.49), a low physical quality of life score (OR = 13.25, 95% CI 3.51-50.08), a low mental quality of life score (OR = 9.22, 95% CI 2.38-35.69), visual impairment (OR = 7.65, 95% CI 1.77-33.14), and hearing impairment (OR = 4.62, 95% CI 1.03-20.66) were independently associated with frailty.Conclusions: Frailty was found to be highly prevalent in the residential care home studied. Since frailty is a reversible condition, identifying the modifiable factors associated to it should be viewed as an important step in planning and implementing targeted, early prevention strategies.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: The effect of falls on changes in body weight is still unknown. This study investigated the extent to which falls can modify the course of body weight in nursing home residents, and aimed to identify the factors that might modulate this effect.Methods: The sample included 132 residents aged ≥60 y who had experienced at least one fall after nursing home admission. Body weight was measured monthly in the 6 mo after the fall in the entire sample, and also in the 6 mo prefall in a subsample (n = 111). Sociodemographic and health data were obtained from medical records. Linear mixed models were used to estimate the average monthly changes in body weight after the fall in the total sample, and as a function of the sociodemographic and medical factors.Results: Falls modified the course of body weight in the total sample (β = −0.28, 95% confidence interval, −0.44 to −0.12, for the change in slope before and after fall) in all age classes and especially in individuals with severe cognitive impairment who received less-frequent informal visits (β = −0.55, 95% confidence interval, −0.87 to −0.22). Individuals aged ≥90 y and those with severe cognitive impairment had a steeper monthly weight decline in the 6 mo postfall, of 0.23 and 0.35 kg greater, respectively, than their younger and cognitively healthier counterparts.Conclusions: Falls may trigger a body weight loss in nursing home residents, especially in the oldest old people and those with severe cognitive impairment who receive little support from informal caregivers. These findings highlight the importance of monitoring nutritional status of people who live in institutions after falls.

Frailty and the risk of infection-related hospitalizations in older age : Differences by sex
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To investigate the extent to which frailty is associated with infection-related hospitalizations in older men and women, and to explore whether, among women, previous exposure to endogenous estrogens in terms of age at menopause and number of pregnancies modify such a relationship.Study design: The sample comprised 2784 participants in the Progetto Veneto Anziani aged ≥65 years. At baseline and after 4.4 years, frailty was identified according to the presence of three or more of the following: weakness, exhaustion, weight loss, low physical activity, and low walking speed. A passive follow-up on infection-related hospitalizations and mortality was performed for 10 years of observation through linkage with regional registers.Main outcome measures: The association between frailty and infection-related hospitalizations was assessed through mixed-effects Cox regressions.Results: Frailty was significantly associated with a 78 % higher risk of infection-related hospitalization, with stronger results in men (hazard ratio = 2.32, 95 % confidence interval 1.63–3.30) than in women (hazard ratio = 1.54, 95 % confidence interval 1.18–2.02). Focusing on women, we found a possible modifying effect for the number of pregnancies but not menopausal age. Women who had experienced one or no pregnancy demonstrated a higher hazard of infection-related hospitalization as a function of frailty (hazard ratio = 3.00, 95 % confidence interval 1.58–5.71) than women who had experienced two or more pregnancies (hazard ratio = 1.68, 95 % confidence interval 1.18–2.39).Conclusion: Frailty in older age increases the risk of infection-related hospitalizations, especially in men. The “immunologic advantage” of the female sex in younger age seems to persist also after menopause as a function of the number of pregnancies a woman has experienced.
