Background: Aging leads to increased visceral adipose tissue (VAT) and reduced skeletal muscle density. To which extent these are associated with the risk of stroke, myocardial infarction (MI), and all‐cause mortality in older adults is unknown. Methods and Results: A total of 3294 70‐year‐old individuals (49.6% women) underwent a health examination in Umeå, Sweden, during 2012 to 2018. VAT and muscle density were measured using dual‐energy x‐ray absorptiometry and peripheral quantitative computed tomography. Cases of stroke, MI, and all‐cause mortality were collected through national registers. Cox regressions were used to calculate hazard ratios (HRs) and 95% CIs per SD greater VAT and per SD lower muscle density. During a mean follow‐up of 3.6 years, there were 108 cases of stroke or MI, and 97 deaths. Greater VAT (adjusted HR [aHR], 1.56; 95% CI, 1.09–2.22), but not lower muscle density (aHR, 1.14; 95% CI, 0.97–1.34), was associated with increased risk of stroke or MI. Neither VAT (aHR, 0.95; 95% CI, 0.65–1.41) nor muscle density (aHR, 1.11; 95% CI, 0.92–1.34) was associated with all‐cause mortality. The association of VAT with stroke or MI was only significant in men (aHR, 1.86; 95% CI, 1.19–2.91) but not women (aHR, 0.60; 95% CI, 0.25–1.42) ( P interaction =0.038). Conclusions: With the limitation of being an observational study, these findings suggest that VAT is an important obesity‐related predictor of cardiovascular risk in 70‐year‐old men, and by implication, that decreasing VAT may potentially reduce their risk of cardiovascular disease.

The aim of the study is to evaluate the effects of the Comprehensive Geriatric Assessment (CGA) for frail older people in Swedish acute hospital settings – the CGA-Swed study. In this study protocol, we present the study design, the intervention and the outcome measures as well as the baseline characteristics of the study participants. The study is a randomised controlled trial with an intervention group receiving the CGA and a control group receiving medical assessment without the CGA. Follow-ups were conducted after 1, 6 and 12 months, with dependence in activities of daily living (ADL) as the primary outcome measure. The study group consisted of frail older people (75 years and older) in need of acute medical hospital care. The study design, randomisation and process evaluation carried out were intended to ensure the quality of the study. Baseline data show that the randomisation was successful and that the sample included frail older people with high dependence in ADL and with a high comorbidity. The CGA contributed to early recognition of frail older people’s needs and ensured a care plan and follow-up. This study is expected to show positive effects on frail older people’s dependence in ADL, life satisfaction and satisfaction with health and social care.

Morale can be viewed as a future-oriented optimism or pessimism regarding challenges associated with aging and is closely related to subjective well-being. Promoting morale in old age could be considered to have important implications for aging well, and increased knowledge about morale in different stages of old age is needed. Hence, the aim of this study was to investigate factors associated with morale in different age groups among old people. Data were derived from a survey conducted in 2016, as a part of the Gerontological Regional Database (GERDA). The sample consisted of 9,047 individuals aged between 65 and 86 years from Ostrobothnia and Southern Ostrobothnia in Finland, and Västerbotten in Sweden. Morale was measured with the Philadelphia Geriatric Center Morale Scale (PGCMS) and regressed upon a number of sociodemographic, social, and health-related factors using linear regression analyses. The results showed that older age was an independent factor explaining lower level of morale. Additionally, the sociodemographic, social, and health-related variables could explain a large proportion of the variance in morale. Perceived loneliness, having gone through a crisis in life, poor self-rated health, and depression were associated with lower morale, and sleeping well with higher morale, in all age groups. Furthermore, the oldest age groups seem to be more exposed to several risk factors of lower morale identified in this study. Multidimensional interventions targeting especially social and mental health and the oldest-old could therefore be recommended.

Background: The Geriatric Depression Scale (GDS) has shown good validity and reliability, but few studies have examined the GDS among very old adults or the Swedish translation. Objectives: Evaluate the validity and reliability of the Swedish version of GDS-15 among very old adults. Methods: In the Umeå85 + /GErontological Regional DAtabase (GERDA) study, 387 participants were assessed with both the GDS-15 and the Montgomery-Åsberg Depression Rating Scale (MADRS). The mean age was 91 years. Concurrent validity between the scales was calculated using Spearman's correlation. We used the Diagnostic and Statistical Manual of Mental Disorders (DSM) V symptom criteria for depression based on MADRS item scores to define depression. We calculated the Area Under the Curve (AUC) and found an optimal cut-off. A convenience sample with 60 individuals was used to calculate test–retest reliability with Cohen’s kappa and Intraclass Correlation Coefficient (ICC). Results: Spearman's correlation coefficients between total scores for GDS-15 and MADRS were 0.60. Cronbach's alpha for the whole scale was 0.73. The AUC was 0.90 for distinguishing major depression, and the recommended cut-off of ≥ 5 showed a sensitivity of 95.2% and specificity of 65.8%. The test–retest showed that Cohen’s kappa was substantial (0.71) and the ICC was excellent (0.95). Conclusions: The Swedish version of the GDS-15 showed good validity and reliability among very old adults. The generally recommended cut-off of ≥ 5 seems reasonable to use with the Swedish version and among very old adults.

High morale could be considered to be an essential part of aging well and increased knowledge of how to prevent a decrease in high morale in very old age could have important implications for policy, and social and health care development. The objective was to identify social and health-related risk factors for a decrease in morale over 5 years in very old people among those with high morale at baseline. The study is based on data derived from the Umeå85+/GERDA study conducted in Northern Sweden and Western Finland. The final sample consisted of 174 individuals who were 85 years and older at baseline and who had completed the follow-up 5 years later. Morale was measured with The Philadelphia Geriatric Center Morale Scale (PGCMS). A set of social and health-related variables were used to test which factors were associated with a decrease in morale over 5 years. Linear regression was used for the multivariable analyses. The sample had a mean change of − 1.3 (SD = 2.5) in PGCMS scores from T1 to T2. The results from the regression analyses showed that development of depressive disorders, increased feelings of loneliness and the death of a child during the follow-up period were associated with a decrease in morale. The results from our study indicate that preventing the development of depressive disorders and increasing loneliness are key factors in preventing a decrease in high morale. Additionally, very old people who have recently lost an adult child should receive adequate psychosocial support.
