- Background: As global aging accelerates, routinely assessing the functional status and morbidity burden of older patients becomes paramount. The aim of this study is to assess the validity of the comprehensive clinical and functional Health Assessment Tool (HAT) based on four cohorts of older adults (60 + years) from the Swedish National study on Aging and Care (SNAC) spanning urban, suburban, and rural areas.Methods: The HAT integrates five health indicators (gait speed, global cognition, number of chronic diseases, and basic and instrumental activities of daily living), providing an individual-level score between 0 and 10. The tool was constructed using nominal response models, first separately for each cohort and then in a harmonized dataset. Outcomes included all-cause mortality over a maximum follow-up of 16 years and unplanned hospital admissions over a maximum of 3 years of follow-up. The predictive capacity was assessed through the area under the curve (AUC) using logistic regressions. For time to death, Cox regressions were performed, and Harrell’s C-indices were reported. Results from the four cohorts were pooled using individual participant data meta-analysis and compared with those from the harmonized dataset.Results: The HAT demonstrated high predictive capacity across all cohorts as well as in the harmonized dataset. In the harmonized dataset, the AUC was 0.84 (95% CI 0.81–0.87) for 1-year mortality, 0.81 (95% CI 0.80–0.83) for 3-year mortality, 0.80 (95% CI 0.79–0.82) for 5-year mortality, 0.69 (95% CI 0.67–0.70) for 1-year unplanned admissions, and 0.69 (95% CI 0.68–0.70) for 3-year unplanned admissions. The Harrell’s C for time-to-death throughout 16 years of follow-up was 0.75 (95% CI 0.74–0.75).Conclusions: The HAT is a highly predictive, clinically intuitive, and externally valid instrument with potential for better addressing older adults’ health needs and optimizing risk stratification at the population level. © The Author(s) 2024.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: We investigated the impact of multiple cardiovascular and neuropsychiatric diseases on all-cause and cause-specific mortality in older adults, considering their functional status. METHODS: This cohort study included 3241 participants (aged >= 60 years) in the Swedish National study of Aging and Care in Kungsholmen (SNAC-K). Number of cardiovascular and neuropsychiatric diseases was categorized as 0, 1, or >= 2. Functional impairment was defined as walking speed of < 0.8m/s. Death certificates provided information on 3- and 5-year mortality. Hazard ratios (HR) were derived from Cox models (all-cause mortality) and Fine-Gray competing risk models (cardiovascular and non-cardiovascular mortality). RESULTS: After 3 years, compared with participants with preserved walking speed and without either cardiovascular or neuropsychiatric diseases, the multivariable-adjusted HR (95% confidence interval) of allcause mortality for people with functional impairment in combination with 0, 1, and >= 2 cardiovascular diseases were 1.88 (1.29-2.74), 3.85 (2.60-5.70), and 5.18 (3.45-7.78), respectively. The corresponding figures for people with 0, 1, and >= 2 neuropsychiatric diseases were, respectively, 2.88 (2.03-4.08), 3.36 (2.314.89), and 3.68 (2.43-5.59). Among people with >= 2 cardiovascular or >= 2 neuropsychiatric diseases, those with functional impairment had an excess risk for 3-year all-cause mortality of 18/100 person-years and 17/100 person-years, respectively, than those without functional impairment. At 5 years, the association between the number of cardiovascular diseases and mortality resulted independent of functional impairment. CONCLUSIONS: Functional impairment magnifies the effect of cardiovascular and neuropsychiatric multimorbidity on mortality among older adults. Walking speed appears to be a simple clinical marker for the prognosis of these two patterns of multimorbidity.

- Background: Geriatric health charts that are similar to pediatric growth charts could facilitate monitoring health changes and predicting care needs in older adults. We aimed to validate an existing composite score (Health Assessment Tool [HAT]) and provide provisional age-specific reference curves for the general older population.Methods: Data came from the Swedish National study on Aging and Care in Kungsholmen (N = 3,363 participants aged 60 years and over examined clinically at baseline and 3 years later). HAT was validated by exploring its relationship with health indicators (logistic regression) and comparing its ability to predict care consumption with that of two of its components, morbidity and disability (receiver operating characteristic curve areas). A flowchart was developed to obtain individual-level HAT scores (nominal response method). Sex-specific health charts were derived by graphing seven percentile curves of age-related HAT change (logistic quantile regression).Results: HAT scores above the age- and sex-specific median were related to good performance in chair-stand tests (odds ratio [OR] = 2.62, 95% confidence interval [CI]: 2.07-3.31), balance and grip tests (interaction balance grip test, OR = 1.15, 95% CI: 1.05-1.25), and good self-rated health (OR = 2.19, 95% CI: 1.77-2.71). Receiver operating characteristic curve areas (HAT vs number of chronic disorders) were formal care, 0.76 versus 0.58 (p value < .001); informal care, 0.74 versus 0.59 (p value < .001); hospital admission, 0.70 versus 0.66 (p value < .001); primary care visits, 0.71 versus 0.69 (p value > .05); and specialty care visits, 0.62 versus 0.65 (p value < .001). HAT consistently predicted medical and social care service use better than disability.Conclusions: HAT is a valid tool that predicts care consumption well and could be useful in developing geriatric health charts to better monitor health changes in older populations.

- Background: The aim of this study is to identify clusters of older persons based on their multimorbidity patterns and to analyze differences among clusters according to sociodemographic, lifestyle, clinical, and functional characteristics. Methods: We analyzed data from the Swedish National Study on Aging and Care in Kungsholmen on 2,931 participants aged 60 years and older who had at least two chronic diseases. Participants were clustered by the fuzzy c-means cluster algorithm. A disease was considered to be associated with a given cluster when the observed/expected ratio was >= 2 or the exclusivity was >= 25%. Results: Around half of the participants could be classified into five clinically meaningful clusters: respiratory and musculoskeletal diseases (RESP-MSK) 15.7%, eye diseases and cancer (EYE-CANCER) 10.7%, cognitive and sensory impairment (CNS-IMP) 10.6%, heart diseases (HEART) 9.3%, and psychiatric and respiratory diseases (PSY-RESP) 5.4%. Individuals in the CNS-IMP cluster were the oldest, with the worst function and more likely to live in a nursing home; those in the HEART cluster had the highest number of co-occurring diseases and drugs, and they exhibited the highest mean values of serum creatinine and C-reactive protein. The PSY-RESP cluster was associated with higher levels of alcoholism and neuroticism. The other half of the cohort was grouped in an unspecific cluster, which was characterized by gathering the youngest individuals, with the lowest number of co-occurring diseases, and the best functional and cognitive status. Conclusions: The identified multimorbidity patterns provide insight for setting targets for secondary and tertiary preventative interventions and for designing care pathways for multimorbid older people.

Tidskriftsartikel (refereegranskat)abstract
- The presence of multiple chronic conditions (i.e., multimorbidity) increases the risk of hospitalisation in older adults. We aimed to examine the association between different multimorbidity patterns and unplanned hospitalisations over 5 years. To that end, 2,250 community-dwelling individuals aged 60 years and older from the Swedish National Study on Aging and Care in Kungsholmen (SNAC-K) were studied. Participants were grouped into six multimorbidity patterns using a fuzzy c-means cluster analysis. The associations between patterns and outcomes were tested using Cox models and negative binomial models. After 5 years, 937 (41.6%) participants experienced at least one unplanned hospitalisation. Compared to participants in the unspecific multimorbidity pattern, those in the cardiovascular diseases, anaemia and dementia pattern, the psychiatric disorders pattern and the metabolic and sleep disorders pattern presented with a higher hazard of first unplanned hospitalisation (hazard ratio range: 1.49-2.05; p < 0.05 for all), number of unplanned hospitalisations (incidence rate ratio (IRR) range: 1.89-2.44; p < 0.05 for all), in-hospital days (IRR range: 1.91-3.61; p < 0.05 for all), and 30-day unplanned readmissions (IRR range: 2.94-3.65; p < 0.05 for all). Different multimorbidity patterns displayed a differential association with unplanned hospital care utilisation. These findings call for a careful primary care follow-up of older adults with complex multimorbidity patterns.

- Purpose: To investigate: (1) the cross-sectional association between polypharmacy, hyperpolypharmacy and presence of prefrailty or frailty; (2) the risk of incident prefrailty or frailty in persons with polypharmacy, and vice versa.Methods: A systematic review and meta-analysis was performed according to PRISMA guidelines. We searched PubMed, Web of Science, and Embase from 01/01/1998 to 5/2/2018. Pooled estimates were obtained through random effect models and Mantel-Haenszel weighting. Homogeneity was assessed with the I-2 statistic and publication bias with Egger's and Begg's tests.Results: Thirty-seven studies were included. The pooled proportion of polypharmacy in persons with prefrailty and frailty was 47% (95% CI 33-61) and 59% (95% CI 42-76), respectively. Increased odds ratio of polypharmacy were seen for prefrail (pooled OR=1.52; 95% CI 1.32-1.79) and frail persons (pooled OR=2.62, 95% CI 1.81-3.79). Hyperpolypharmacy was also increased in prefrail (OR=1.95; 95% CI 1.41-2.70) and frail (OR=6.57; 95% CI 9.57-10.48) persons compared to robust persons. Only seven longitudinal studies reported data on the risk of either incident prefrailty or frailty in persons with baseline polypharmacy. A significant higher odds of developing prefrailty was found in robust persons with polypharmacy (pooled OR=1.30; 95% CI 1.12-1.51). We found no papers investigating polypharmacy incidence in persons with prefrailty/frailty.Conclusions: Polypharmacy is common in prefrail and frail persons, and these individuals are also more likely to be on extreme drug regimens, i.e. hyperpolypharmacy, than robust older persons. More research is needed to investigate the causal relationship between polypharmacy and frailty syndromes, thereby identifying ways to jointly reduce drug burden and prefrailty/frailty in these individuals.

- Background One’s physical function and physical activity levels can predispose or protect from the development of respiratory infections. We aimed to explore the associations between pre-pandemic levels of physical function and physical activity and the development of COVID-19-like symptoms in Swedish older adults.Methods We analyzed data from 904 individuals aged ≥ 68 years from the population-based Swedish National study on Aging and Care in Kungsholmen. COVID-19-like symptoms were assessed by phone interview (March–June 2020) and included fever, cough, sore throat and/or a cold, headache, pain in muscles, legs and joints, loss of taste and/or odor, breathing difficulties, chest pain, gastrointestinal symptoms, and eye inflammation. Muscle strength, mobility, and physical activity were examined in 2016–2018 by objective testing. Data were analyzed using logistic regression models in the total sample and stratifying by age.Results During the first outbreak of the pandemic, 325 (36%) individuals from our sample developed COVID-19-like symptoms. Those with slower performance in the chair stand test had an odds ratio (OR) of 1.5 (95% confidence interval [CI] 1.1–2.1) for presenting with COVID-19-like symptoms compared to better performers, after adjusting for potential confounders. The association was even higher among people aged ≥ 80 years (OR 2.6; 95% CI 1.5–4.7). No significant associations were found between walking speed or engagement in moderate-to-vigorous physical activity and the likelihood to develop COVID-19-like symptoms.Conclusion Poor muscle strength, a possible indicator of frailty, may predispose older adults to higher odds of developing COVID-19-like symptoms, especially among the oldest-old.

Forskningsöversikt (refereegranskat)abstract
- Slow gait speed has been shown to predict incident dementia and cognitive decline in older individuals. We aimed to summarize the evidence concerning the association of slow gait speed with cognitive decline and dementia, and discuss the possible shared pathways leading to cognitive and motor impairments, under the unifying hypothesis that body and mind are intimately connected. This is a scoping review supported by a systematic search of the literature, performed on PubMed and Web of Science. Longitudinal studies providing information on the role of gait speed in the prediction of cognitive decline and dementia in cognitively intact people and in those with initial cognitive impairment were eligible. Of 39 studies selected, including overall 57,456 participants, 33 reported a significant association between gait speed and cognitive outcomes, including dementia. Neurodegenerative pathology and cerebrovascular burden may damage cerebral areas involved in both cognitive functions and motor control. At the same time, systemic conditions, characterized by higher cardiorespiratory, and metabolic and inflammatory burden, can affect a number of organs and systems involved in motor functions, including the brain, having ultimately an impact on cognition. The interplay of body and mind seems relevant during the development of cognitive decline and dementia. The measurement of gait speed may improve the detection of prodromal dementia and cognitive impairment in individuals with and without initial cognitive deficits. The potential applicability of such a measure in both clinical and research settings points at the importance of expanding our knowledge about the common underlying mechanisms of cognitive and motor decline.

- Background. Life's Simple 7 (LS7) aims to promote ideal cardiovascular health (CVH). Its association with different cognitive states in the older old is unclear.Objectives. To assess the associations of LS7 with transitions across normal cognition, cognitive impairment, no dementia (CIND), and dementia and evaluate cognitive impairment-free years of life by LS7-defined CVH levels in older adults.Methods. This cohort study included 2746 participants from the Swedish National Study on Aging and Care in Kungsholmen, regularly examined over 15 years. Total LS7 scores were created and dichotomized into worse and better CVH categories. The associations of LS7 total scores and CVH categories with cognitive states were assessed with multistate models in the whole sample and in younger old (<78 years) and older old adults (≥78 years) separately. Cognitive impairment-free life years by CVH categories were then predicted.Results. A 1-point increment in the LS7 total score was associated with lower dementia risk in younger old adults (hazard ratio: 0.87 [0.78–0.97]) but not in older old adults (1.04 [0.97–1.13]). Better CVH was also associated with a lower risk of transition from normal cognition to CIND (0.76 [0.61–0.95]) and from normal cognition to dementia (0.42 [0.21–0.82]) in younger old adults. In younger old adults, those with better CVH were predicted to have two-to-three more cognitive impairment-free life years than those with worse CVH.Conclusion. Maintaining LS7-defined ideal CVH seems relevant in younger old adults but not in older old adults when considering the potential protective effects against cognitive impairment.

- Objectives: To examine the associations of multimorbidity patterns with health-related quality of life (HRQL) in rural-dwelling older adults in China, and to explore to what extent their associations were mediated by functional dependence and depressive symptoms. Design: Population-based cross-sectional study. Setting and participants: 1497 participants (age >= 60 years; 66.4% women) in the 2014-2016 examination of the Confucius Hometown Aging Project who were living in a rural community near Qufu, Shandong, China. Measures: Data on demographics, lifestyles, chronic health conditions, and use of medications were collected through interviews, clinical examinations, and laboratory tests. Multimorbidity was defined as co-occurrence of >2 chronic diseases in the same person. The 15-item Geriatric Depression Scale (GDS-15) was used to assess depressive symptoms, and EQ-5D-3L was used to assess HRQL. Results: Multimorbidity was present in 83.8% of the participants (women vs men: 85.5% vs 80.6%, P = .015). Exploratory factor analysis identified 4 patterns of multimorbidity, that is, patterns of cardiovascular-degenerative, respiratory, neurologic-thyroid, and metabolic-cognitive-cerebrovascular diseases. The neurologic-thyroid disease pattern did not show a significant association with HRQL. The 3 other patterns were associated with poor HRQL and had a diverse impact on different dimensions of HRQL. Mediation analysis suggested that functional dependence and the presence of depressive symptoms could mediate 24.8% and 21.8%, respectively, of the association between the number of chronic diseases and poor HRQL. Conclusions/Implications: Multimorbidity is associated with poor HRQL in older adults, in which functional dependence and depressive symptoms partly mediate their associations. Prevention and proper management of dependence and depressive symptoms in older people with multimorbidity may help maintain and improve quality of life.
