- The association between decline in physical function and age-related conditions, such as reduced cognitive performance and vascular disease, may be explained by genetic influence on shared biological pathways of importance for aging. The apolipoprotein F (APOE) gene is well-known for its association with Alzheimer's disease, but has also been related to other disorders of importance for aging. The aim of this study was to investigate possible associations between APOE allele status and physical function in a population-based longitudinal study of older individuals. In 2005, at the age of 75, 622 individuals underwent neuropsychiatric and physical examinations, including tests of physical function, and APOE-genotyping. Follow-up examinations were performed at age 79. A significantly larger decline in grip strength (p = 0.015) between age 75 and 79 was found when comparing APOE epsilon 4 allele carriers with non carriers [10.3 (+/- 10.8) kg versus 7.8 (+/- 10.1) kg]. No association was seen with decline in gait speed, chair-stand, or balance. The association with grip strength remained after correction for cognitive and educational level, depression, cardiovascular disease, stroke, and BMI.

- Objectives: We evaluated birth cohort differences in depressive symptom burden, prevalence of depression diagnoses, and neuroticism, among Swedish 70-year-olds examined between 1976 and 2016. Methods: We used a repeated cross-sectional design examining four representative population samples of Swedish 70-year-olds (total n=2279) with identical methods in 1976-77 (n=392), 1992-93 (n=226), 2000-02 (n=487), and 2014-16 (n=1166). Depressive symptom burden was rated with the Montgomery Åsberg Depression Rating Scale. Major depression was diagnosed according to DSM-5, and minor depression according to DSM-IV-TR research criteria. Neuroticism was rated with the Eysenck Personality Inventory. Results: For women in 2014-16, MADRS score (4.4 vs. 6.1 vs. 5.8; p<0.05) and neuroticism (6.6 vs. 7.7 vs. 9.2; p<0.05) were lower compared to 1992-93 and 1976-77, and the prevalence of any depression was lower compared to 2000-02 and 1992-93 (10.9% vs. 16.9% vs. 18.1%; p<0.05). For men, we observed no birth cohort differences in depression, while neuroticism was found to be lower in 2014-16 compared to 1976-77 among men without depression (5.1 vs. 5.9; p<0.01). The sex difference for MADRS and neuroticism declined between 1976-77 and 2014-16 (cohort*sex p<0.05). Conclusions: Depressive burden and neuroticism decreased in 70-year-old women between 1976 and 2016.

- Objective Little is known about the role of gender expression (femininity, masculinity, or androgyny) in relation to sex differences in depression. This study tested if gender expression was associated with depression and burden of depressive symptoms in a 70-year-old population. Methods A cross-sectional population-based sample of 70-year-olds from The Gothenburg H70 Birth Cohort Study (n = 1203) was examined in 2014-16. Data were collected using psychiatric examinations and structured questionnaires, including the Positive-Negative Sex-Role Inventory to assess gender expression. Depression was diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders criteria, and symptom burden was assessed with Montgomery angstrom sberg Depression Rating Scale (MADRS). Results Gender expression was related to MADRS score and depression diagnosis. In fully adjusted models, feminine traits with low social desirability (FEM-) were associated with a higher MADRS score (R(2)0.16; B 0.16; CI 0.1-0.2), while androgyny (t ratio) (R(2)0.12; B 0.42; CI 0.1-0.7) and masculine traits with high social desirability (MAS+) (R(2)0.13; B -0.06; CI -0.1--0.01) were associated with a lower MADRS score. Also, feminine traits with low social desirability (FEM-) were positively associated with depression (OR 1.04; CI 1.01-1.1). No associations between depression and masculinity or androgyny were observed in adjusted models. There were no interactions between sex and gender expression in relation to depression or MADRS score, indicating that the effects of gender expression were similar in men and women. Conclusions We found that gender expression was associated to both depression and burden of depressive symptoms. More specifically, we found that femininity was associated to higher levels of depression, irrespective of biological sex. In addition, masculinity and androgyny were associated with lower levels of depression. These results highlight the importance of taking gender expression into consideration when studying sex differences in depression among older populations in future studies.

- Depression and dementia in the elderly have been suggested to share similar risk factors and pathogenetic background, and recently the authors reported that the APOEɛ4 allele is a risk factor for both disorders in the general population. The aim of the present study was to examine the influence of the well-known polymorphisms rs1799752 in the angiotensin-converting enzyme (ACE) and rs5186 in the angiotensin receptor II type 1 (AGTR1) on late-life depression and dementia in a population-based Swedish cohort of older individuals followed over 12 years.In 2000-2001, 900 individuals underwent neuropsychiatric and neuropsychological examinations. Follow-up evaluations were performed in 2005-2006 and 2009-2010, and register data on dementia to 2012 were included. Cross-sectional associations between genotypes/alleles and depression and dementia at baseline and between genotypes/alleles and depression on at least one occasion during the study period and dementia onset to 2012 were investigated.As previously found for rs1799752 in ACE, rs5186 in AGTR1 was associated with dementia at baseline (OR: 3.25 [CI: 1.42-7.06], z=2.90, p=0.004). These associations became substantially weaker, or disappeared, when dementia onset to 2012 was included. For rs1799752 this could be explained by a significant association with age at onset (mean: 79.5 [SD: 6.45] years for risk-genotype carriers and 81.7 [SD: 7.12] years for carriers of other genotypes, b=-2.43, t=-2.38, df=192, p=0.02). When individuals with major depression on at least one occasion were analyzed, a significant association (OR: 2.14 [95% CI: 1.13-4.20], z=2.28, p=0.02), remaining after exclusion of dementia, with rs1799752 in ACE was found.In this population-based sample of older individuals, genetic variations in ACE seem to be important both for late-life major depression and dementia.

- Introduction: Longitudinal studies examining the effect of endogenous estrogens on dementia risk are needed to understand why women have higher dementia incidence than men after age 85. Methods: A population-based sample of women with natural menopause (N = 1364) from Gothenburg, Sweden, was followed from 1968-2012. Information on endogenous estrogens (age at menarche and menopause, number of pregnancies, and months of breastfeeding) was obtained from interviews in 1968-1992. Dementia was diagnosed according to established criteria based on information from neuropsychiatric examinations and close informant interviews. Results: We found that longer reproductive period was associated with increased risk of dementia (hazard ratio [HR] per year 1.06, 95% confidence interval [CI] 1.03-1.20) and Alzheimer's disease (AD) (1.06, 1.02-1.11), particularly for those with dementia (1.10, 1.04-1.17) and AD (1.15, 1.06-1.26) onset after age 85. Discussion: These results may explain why women have higher dementia incidence compared to men after age 85, the age with the highest number of dementia cases.

- To improve health care for older persons, we need to learn more about ageing, e.g. identify protective factors and early markers for diseases. The Gothenburg H70 Birth Cohort Studies (the H70 studies) are multidisciplinary epidemiological studies examining representative birth cohorts of older populations in Gothenburg, Sweden. So far, six birth cohorts of 70-year-olds have been examined over time, and examinations have been virtually identical between studies. This paper describes the study procedures for the baseline examination of the Birth cohort 1944, conducted in 2014-16. In this study, all men and women born 1944 on specific dates, and registered as residents in Gothenburg, were eligible for participation (n=1839). A total of 1203 (response rate 72.2%; 559 men and 644 women; mean age 70.5years) agreed to participate in the study. The study comprised sampling of blood and cerebrospinal fluid, psychiatric, cognitive, and physical health examinations, examinations of genetics and family history, use of medications, social factors, functional ability and disability, physical fitness and activity, body composition, lung function, audiological and ophthalmological examinations, diet, brain imaging, as well as a close informant interview, and qualitative studies. As in previous examinations, data collection serves as a basis for future longitudinal follow-up examinations. The research gained from the H70 studies has clinical relevance in relation to prevention, early diagnosis, clinical course, experience of illness, understanding pathogenesis and prognosis. Results will increase our understanding of ageing and inform service development, which may lead to enhanced quality of care for older persons.

- Self-rated health (SRH) strongly predicts mortality. Twin studies estimate that genetic factors account for a substantial part of the variability in SRH. Variations in the gene FOXO3 (forkhead box O3), and in genes located at the APOE (apoplipoprotein E) locus, are associated with longevity. This study explores the relationship between SRH and genetic variation related to longevity, in a population-based cohort of older individuals. SRH was assessed among 1520 individuals aged 75 to 87, and five single nucleotide polymorphisms (SNPs), in APOE, TOMM40 (translocase of outer mitochondrial membrane 40 homolog), and FOXO3 were genotyped. Two SNPs (rs10457180 and rs2802292) in FOXO3 were associated with SRH (OR=2.18 [CI: 1.27-3.76], p=0.005 and OR=1.63 [CI: 1.11-2.40], p=0.013), while no associations were found with SNPs in APOE and TOMM40. Several factors, such as depression, cardiovascular disease (CVD), and diabetes, were related to SRH, but the only factor that had any influence on the association with FOXO3 was CVD. Still, after including CVD as a covariate, the associations between FOXO3 SNPs and SRH remained significant. Our results suggest that FOXO3 is related to SRH in older individuals. This relationship seems to be influenced by CVD, but not by mental and cognitive status.
