RESUMEN
BACKGROUND: Little is known about alcohol consumption among the oldest old. OBJECTIVE: To compare alcohol use and drinking patterns among 85 year olds born three decades apart. DESIGN: Cross-sectional. SETTING: The Gothenburg H70 Birth Cohort Studies. SUBJECTS: About 1,160 85 year olds born in 1901-02, 1923-24, and 1930. METHODS: Self-reported questions about alcohol included how often study participants drank beer, wine, and spirits and how many centilitres in total/week. Risk consumption was defined as ≥100 g alcohol/week. Descriptive statistics and logistic regression were used to explore cohort characteristics, differences in proportions, factors associated with risk consumption and 3-year mortality. RESULTS: The proportion of at-risk drinkers increased from 4.3 to 14.9% (9.6-24.7% in men and 2.1-9.0% in women). The proportion of abstainers decreased from 27.7 to 12.9%, with the largest decrease observed among women (29.3-14.1%). Controlling for sex, education and marital status, 85 year olds in the later-born cohorts were more likely to be risk consumers than those in the earlier-born cohort [odds ratio (OR) 3.1, 95% confidence nterval (CI) 1.8-5.6]. The only factor associated with an increased likelihood was male sex (OR 3.7, 95% CI 1.0-12.7 and OR 3.2, 95% CI 2.0-5.1). There were no associations between risk consumption of alcohol and 3-year mortality in any of the cohorts. CONCLUSION: Alcohol consumption and the number of risk consumers among 85 year olds have increased considerably. This could have large public health consequences since older adults are more sensitive to alcohol's adverse health effects. Our findings show the importance of detecting risk drinkers also in the oldest old.

PURPOSE: To investigate potential interactions between dietary patterns and genetic factors modulating risk for Alzheimer's disease (AD) in relation to incident dementia. METHODS: Data were derived from the population-based Gothenburg H70 Birth Cohort Studies in Sweden, including 602 dementia-free 70-year-olds (examined 1992-93, or 2000-02; 64% women) followed for incident dementia until 2016. Two factors from a reduced rank regression analysis were translated into dietary patterns, one healthy (e.g., vegetables, fruit, and fish) and one western (e.g., red meat, refined cereals, and full-fat dairy products). Genetic risk was determined by APOE ε4 status and non-APOE AD-polygenic risk scores (AD-PRSs). Gene-diet interactions in relation to incident dementia were analysed with Cox regression models. The interaction p value threshold was < 0.1. RESULTS: There were interactions between the dietary patterns and APOE ε4 status in relation to incident dementia (interaction p value threshold of < 0.1), while no evidence of interactions were found between the dietary patterns and the AD-PRSs. Those with higher adherence to a healthy dietary pattern had a reduced risk of dementia among ε4 non-carriers (HR: 0.77; 95% CI: 0.61; 0.98), but not among ε4 carriers (HR: 0.86; CI: 0.63; 1.18). Those with a higher adherence to the western dietary pattern had an increased risk of dementia among ε4 carriers (HR: 1.37; 95% CI: 1.05; 1.78), while no association was observed among ε4 non-carriers (HR: 0.99; CI: 0.81; 1.21). CONCLUSIONS: The results of this study suggest that there is an interplay between dietary patterns and APOE ε4 status in relation to incident dementia.

BACKGROUND: Old-age dementias are known to disproportionally affect women as well as individuals with low educational attainment. The higher lifetime risk of dementia among women is usually attributed to their longer life expectancy. However, the impact of sex, and subsequent gender inequity, is likely to be more multifaceted than this explanation implies. Not least because of historical inequities in access to education between the sexes and the gender and socio-economic gradients in risk factors such as stress, depression and social isolation. Consequently, the present study sought to test whether differences in educational attainment and experiences of general psychological distress mediate the association between female sex and dementia. METHODS: The study utilizes data obtained through the Gothenburg H70 Birth Cohort Study and the Prospective Populations Study on Women (n = 892). Data were analysed using Confirmatory Factor Analysis (CFA) and Structural Equation Modelling (SEM) with Weighted Least Squares Means and Variance adjusted (WLSMV) estimation. General psychological distress was indicated by a latent variable and constructed from five manifest items (previous depression, stress, self-esteem, chronic loneliness and satisfaction with social situation) that were all measured at baseline. RESULTS: While the results could not corroborate that education directly mediates the effect of sex on dementia, level of distress was predicted by both female sex (0.607, p < .001) and education (- 0.166, p < .01) and, in turn, shown to be significantly associated with dementia (0.167, p < .05), also after controlling for confounders. When time from baseline to diagnosis was increased through sequential exclusion of dementia cases, the effect of distress on dementia was no longer significant. CONCLUSION: The overall findings suggest that social (dis) advantage predicts general psychological distress, which thereby constitutes a potential, and rarely acknowledged, pathway between female sex, education, and dementia. They further underline the importance of attending to both education and distress as 'gendered' phenomena when considering the nature of their associations with dementia. However, the possibility of reverse causality bias must be acknowledged and the need for longitudinal studies with longer follow-up stressed.

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 70.5 years) 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.

BACKGROUND: The older adult population is increasing worldwide, as is the number of older adults who consume alcohol. Although there is a growing body of research on alcohol consumption among older people, few studies focus on changes in at-risk consumption over time across well-defined birth cohorts of older adults. METHODS: This study used a serial cross-sectional design in order to compare alcohol consumption patterns among birth cohorts of Swedish 70-year-olds (total n = 2,268) examined in 1976 to 1977 (n = 393), 1992 to 1993 (n = 248), 2000 to 2002 (n = 458), and 2014 to 2016 (n = 1,169). Participants took part in a multidisciplinary study on health and aging. Face-to-face interviews were conducted by healthcare professionals. Protocols regarding alcohol consumption were similar for all cohorts. The volume of weekly alcohol consumption was estimated during the past month. At-risk consumption was defined as ≥100 g alcohol/wk corresponding roughly to the National Institute on Alcohol Abuse and Alcoholism definition of heavy consumption. RESULTS: The proportion of at-risk consumers among men increased from 16.1% in 1976 to 1977 to 29.9% in 2000 to 2002 (p = 0.001) and 45.3% in 2014 to 2016 (p < 0.001). In women, proportions were low in 1976 to 1977 (0.5%) and 1992 to 1993 (2.0%; p = 0.134), but increased to 9.5% in 2000 to 2002 (p < 0.001) and 24.3% in 2014 to 2016 (p < 0.001). The male:female ratio regarding consumption of ≥100 g/wk decreased from 32.2:1 in 1976 to 1977 to 3.1:1 in 2000 to 2002 to 1.9:1 in 2014 to 2016. Spirit consumption decreased dramatically among men during the study period, while women reported very low spirit consumption at all examinations. Wine consumption increased in both sexes between 2000 to 2002 and 2014 to 2016. Beer consumption increased among men between 2000 to 2002 and 2014 to 2016. CONCLUSIONS: Recent cohorts of 70-year-olds in Sweden report significantly higher levels of alcohol consumption than previous cohorts. There was a dramatic increase in at-risk consumption among 70-year-olds from the 1970s to the mid-2010s, and this was particularly pronounced among women.

OBJECTIVES: Attributions for attempting suicide were explored in older adults with and without serious physical illness. METHODS: An open-ended question was used to explore attributions for attempting suicide in 101 hospitalized persons aged 70+. Serious physical illness was defined as a score of 3 or 4 on any of the 13 non-psychiatric organ categories in the Cumulative Illness Rating Scale for Geriatrics. RESULTS: Roughly one-third of hospitalized persons with (22/62) and without (12/39) serious physical illness attributed the suicide attempt to somatic distress. Among 70- to 79-year-olds, seriously physically ill patients were more likely than healthier patients to attribute their attempt to psychological pain (84% vs. 48%, p = 0.013). There were no significant differences in attributions in persons with and without serious health problems in the 80+ group. CONCLUSIONS: The processes by which physical illness confers risk for attempted suicide in older adulthood may be age dependent. Interventions are needed to mitigate psychological pain in physically ill older patients, especially those in their seventies. Research is needed to understand how the psychological processes that influence the desire for suicide change across older adulthood. Copyright © 2015 John Wiley & Sons, Ltd.

PURPOSE: Physical illness has been shown to be a risk factor for suicidal behaviour in older adults. The association between functional disability and suicidal behaviour in older adults is less clear. The aim of this study was to examine the relationship between functional disability and death wishes in late life. METHODS: Data from 11 population studies on depression in persons aged 65 and above were pooled, yielding a total of 15,890 respondents. Level of functional disability was trichotomised (no, intermediate, high). A person was considered to have death wishes if the death wish/suicidal ideation item of the EURO-D scale was endorsed. Odds ratios for death wishes associated with functional disability were calculated in a multilevel logistic regression model. RESULTS: In total, 5 % of the men and 7 % of the women reported death wishes. Both intermediate (OR 1.89, 95 % CI 1.42; 2.52) and high functional disability (OR 3.22, 95 % CI 2.34; 4.42) were associated with death wishes. No sex differences could be shown. Results remained after adding depressive symptoms to the model. CONCLUSIONS: Functional disability was independently associated with death wishes in older adults. Results can help inform clinicians who care for older persons with functional impairment.

Introduction: There are few studies investigating genetic factors related to suicidal ideation or behavior in older adult populations. Our aim was to test associations between passive and active suicidal ideation and polygenic risk scores (PRSs) for suicidality and other traits of relevance for suicidality in old age (i.e. depression, neuroticism, loneliness, Alzheimer's disease, cognitive performance, educational attainment, and several specified vascular diseases) in a population-based sample aged 70 years and older. Methods: Participants in the prospective H70 study in Gothenburg, Sweden, took part in a psychiatric examination that included the Paykel questions on active and passive suicidal ideation. Genotyping was performed with the Neurochip (Illumina). After quality control of the genetic data the sample included 3467 participants. PRSs for suicidality and other related traits were calculated based on summary statistics from recent GWASs of relevance. Exclusion of persons with dementia or incomplete data on suicidal ideation yielded 3019 participants, age range 70-101 years. Associations between past year suicidal ideation (any level) and selected PRSs were analysed using general estimation equation (GEE) models, adjusted for sex and age. Results: We observed associations between passive/active suicidal ideation and PRSs for depression (three versions), neuroticism, and general cognitive performance. After excluding individuals with current major depressive disorder (MDD), similar associations were seen with PRS for neuroticism, general cognitive performance and two PRSs for depression. No associations were found between suicidal ideation and PRSs for suicidality, loneliness, Alzheimer's disease, educational attainment, or vascular disease. Discussion: Our results could indicate which types of genetic susceptibility that are of importance for suicidality in old age, and these findings can help to shed light on potential mechanisms that may be involved in passive and active suicidal ideation in late-life, also in those with no current MDD. However, due to the limited sample size, the results need to be interpreted with caution until replicated in larger samples.
RESUMEN
Background: Longitudinal studies are essential to understand the ageing process, and risk factors and consequences for disorders, but attrition may cause selection bias and impact generalizability. We describe the 1930 cohort of the Gothenburg H70 Birth Cohort Studies, followed from age 70 to 88, and compare baseline characteristics for those who continue participation with those who die, refuse, and drop out for any reason during follow-up. Methods: A population-based sample born 1930 was examined with comprehensive assessments at age 70 (N = 524). The sample was followed up and extended to increase sample size at age 75 (N = 767). Subsequent follow-ups were conducted at ages 79, 85, and 88. Logistic regression was used to analyze baseline characteristics in relation to participation status at follow-up. Results: Refusal to participate in subsequent examinations was related to lower educational level, higher blood pressure, and lower scores on cognitive tests. Both attrition due to death and total attrition were associated with male sex, lower educational level, smoking, ADL dependency, several diseases, poorer lung function, slower gait speed, lower scores on cognitive tests, depressive symptoms, and a larger number of medications. Attrition due to death was also associated with not having a partner. Conclusions: It is important to consider different types of attrition when interpreting results from longitudinal studies, as representativeness and results may be differently affected by different types of attrition. Besides reducing barriers to participation, methods such as imputation and weighted analyses can be used to handle selection bias.
RESUMEN
BACKGROUND: The role of anxiety in late-life suicidal behavior has received relatively little attention. The aim was to explore the association between anxiety symptoms and suicidal feelings in a population sample of 70-year-olds without dementia, and to test whether associations would be independent of depression. METHODS: Face-to-face interviews (N = 560) were carried out by psychiatric nurses and past month symptoms were rated with the Comprehensive Psychopathological Rating Scale (CPRS). The Brief Scale for Anxiety (BSA) was derived from the CPRS to quantify anxiety symptom burden. Past month suicidal feelings were evaluated with the Paykel questions. RESULTS: Anxiety symptom burden was associated with suicidal feelings and the association remained after adjusting for major depression. One individual BSA item (Inner tension) was independently associated with suicidal feelings in a multivariate regression model. The association did not remain, however, in a final model in which depression symptoms replaced depression diagnosis. CONCLUSIONS: Results from this population study suggest an association between anxiety and suicidal feelings in older adults. The role of anxiety and depression symptoms needs further clarification in the study of suicidal behavior in late life.

Older adults of today consume more alcohol, yet knowledge about the factors associated with different consumption levels is limited in this age group. Based on the data from a population-based sample (n = 1156, 539 men and 617 women) in The Gothenburg H70 Birth Cohort Study 2014−16, we examined sociodemographic, social, and health-related factors associated with alcohol consumption levels in 70-year-olds, using logistic regression. Total weekly alcohol intake was calculated based on the self-reported amount of alcohol consumed. Alcohol consumption was categorized as lifetime abstention, former drinking, moderate consumption (≤98 g/week), and at-risk consumption (>98 g/week). At-risk consumption was further categorized into lower at-risk (98−196 g/week), medium at-risk (196−350 g/week), and higher at-risk (≥350 g/week). We found that among the 1156 participants, 3% were lifetime abstainers, 3% were former drinkers, 64% were moderate drinkers, and 30% were at-risk drinkers (20% lower, 8% medium, 2% higher). Among several factors, former drinking was associated with worse general self-rated health (OR 1.65, 95% CI 1.08−2.51) and lower health-related quality of life (measured by physical component score) (OR 0.94, 95% CI 0.91−0.97), higher illness burden (OR 1.16, 95% CI 1.07−1.27), and weaker grip strength (OR 0.96, 95% CI 0.94−0.98). Higher at-risk drinkers more often had liver disease (OR 11.41, 95% CI 3.48−37.37) and minor depression (OR 4.57, 95% CI 1.40−14.95), but less contacts with health care (OR 0.32, 95% CI 0.11−0.92). Our findings demonstrate the importance of classifications beyond abstinence and at-risk consumption, with implications for both the prevention and clinical management of unhealthy consumption patterns in older adults.

OBJECTIVES: To describe representativeness in the Gothenburg H70 1930 Birth Cohort Study. DESIGN: Repeated cross-sectional examinations of a population-based study. SETTING: Gothenburg, Sweden. PARTICIPANTS: All residents of Gothenburg, Sweden, born on specific birth dates in 1930 were invited to a comprehensive health examination at ages 70, 75, 79, 85 and 88. The number of participants at each examination was 524 at age 70, 767 at age 75, 580 at age 79, 416 at age 85, and 258 at age 88. PRIMARY OUTCOME MEASURES: We compared register data on sociodemographic characteristics and hospital discharge diagnoses between participants and (1) refusals, (2) all same-aged individuals in Gothenburg and (3) all same-aged individuals in Sweden. We also compared mortality rates between participants and refusals. RESULTS: Refusal rate increased with age. At two or more examination waves, participants compared with refusals had higher educational level, more often had osteoarthritis, had lower mortality rates, had lower prevalence of neuropsychiatric, alcohol-related and cardiovascular disorders, and were more often married. At two examination waves, participants compared with same-aged individuals in Gothenburg had higher education and were more often born in Sweden. At two examination waves or more, participants compared with same-aged individuals in Sweden had higher education, had higher average income, less often had ischaemic heart disease, were less often born in Sweden and were more often divorced. CONCLUSIONS: Participants were more similar to the target population in Gothenburg than to refusals and same-aged individuals in Sweden. Our study shows the importance of having different comparison groups when assessing representativeness of population studies, which is important in evaluating generalisability of results. The study also contributes unique and up-to-date knowledge about participation bias in these high age groups.

BACKGROUND: Older adults have high suicide rates. We investigated potential time trends in the prevalence of passive and active suicidal ideation in 85-year-olds. Further, we examined factors associated with such ideation in this age group. METHODS: Population-based samples of 85-year-olds were interviewed in 1986 (N = 347), 2008 (N = 426) and 2015 (N = 320). Past-month passive/active suicidal ideation was evaluated with the Paykel questions. RESULTS: Reporting any type of passive or active suicidal ideation was less common in 2008 (7.3%, p < 0.001) and 2015 (7.2%, p < 0.001) compared to 1986 (16.4%). The change was driven by decreases in passive ideation. Passive/active suicidal ideation was associated with higher MADRS score (OR: 1.2, 95% CI: 1.1-1.2, p < 0.001), institution residence (OR: 3.9, 95% CI: 1.7-8.9, p = 0.001) and feelings of loneliness (OR: 2.7, 95% CI: 1.4-5.2, p = 0.003). When stratified by sex, it was associated with institution residence (OR: 3.7, 95% CI: 1.4-9.9, p = 0.008) and feelings of loneliness (OR: 3.0, 95% CI: 1.4-6.3, p = 0.005) in women. In men, we observed a tenfold higher risk in those without partners (OR: 9.8, 95% CI: 2.9-33.5, p < 0.001). LIMITATIONS: While differential three-year mortality was not observed in 1986, mortality was higher among non-participants in 2008 and 2015. This might have inflated cohort differences in passive/active suicidal ideation. CONCLUSION: An initial decrease in the prevalence of passive/active suicidal ideation in 85-year-olds was observed but this positive trend did not persist. Results underline that preventive strategies targeting loneliness and focusing on institutional settings are needed, as are interventions for men without partners.

Relatively little research attention has been paid to sex issues in late life suicidal behaviour. The aim was to compare clinical characteristics of women and men aged 70+ who were hospitalized after a suicide attempt. We hypothesized higher depression and anxiety scores in women, and we expected to find that men would more often attribute the attempt to health problems and compromised autonomy. Participants (56 women and 47 men, mean age 80) were interviewed by a psychologist. In addition to psychiatric and somatic health assessments, participants responded to an open-ended question concerning attributions of the attempt. There were no sex differences in depression and anxiety. Forty-five percent of the men and 14% of the women had a history of substance use disorder (p = 0.02). At least one serious physical disability was noted in 60.7% of the women and 53.2% of the men (p = 0.55). Proportions attributing their attempt to somatic illness did not differ (women, 14.5% vs. men 17.4%, p = 0.79), and similar proportions attributed the attempt to reduced autonomy (women, 21.8% vs. men, 26.1%, p = 0.64). We found strikingly similar figures for depression scores, functional disability and attributions for attempting suicide in older men and women. Larger studies are needed in diverse settings as sex differences might be influenced by cultural context.
