Sex differences in dementia: on the potentially mediating effects of educational attainment and experiences of psychological distress.

ABSTRACT: 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?

Project description:The COVID-19 pandemic has disrupted lives around the world. Autistic adults are at higher risk for co-occurring medical and psychiatric conditions and may be more prone to difficulties adapting to pandemic-related changes and social distancing mandates and coping with ongoing uncertainties. On the other hand, the pandemic may lead to greater understanding and acceptance of accommodations in the broader community that may facilitate supports for autistic adults beyond the pandemic. To learn more about their early pandemic experiences, online surveys were sent to independent adults enrolled in the Simons Powering Autism Research Knowledge (SPARK). The first survey was open from March 30 to April 19, 2020; a follow-up survey sent to original responders was open from May 27 to June 6, yielding 396 participants with data for both surveys. We found that adults who were female, younger, had prior diagnoses of a mental health condition, personal COVID-19 experience (i.e., knowing someone who had symptoms or tested positive) or less frequent hope for the future reported the greatest negative impacts. Decrease in feelings of hopefulness over time predicted greater psychological distress at T2, accounting for T1 impact and distress levels and increases in total COVID-19 impact. Less perceived benefit of online services also predicted later distress. Although there tends to be a focus on coping with negative effects of the pandemic, mental health providers may consider approaches that focus on positives, such as fostering hope and understanding factors that facilitate benefit from online services. LAY SUMMARY: Autistic adults may be at risk for psychological distress during the COVID-19 pandemic. The current study suggests that autistic adults who were younger, female, had a mental health diagnosis before the pandemic and knew someone who showed symptoms or tested positive for COVID-19 reported more areas negatively impacted by COVID-19 and greater difficulty coping with those effects. Decreases in hope over time were associated with greater psychological distress. Less perceived benefit from online services also predicted distress 2 months later. These results suggest important areas to further explore as we develop supports for autistic adults during the pandemic.

Project description:BackgroundIschaemia without obstructive coronary arteries (INOCA) is more prevalent in women and associated with psychological distress. Pharmacological treatment goals are angina relief and cardiovascular risk management. The present study aims to examine sex differences in cardiac and non-cardiac medication use, as well as medication and sex differences related to consistent psychological distress in patients with suspected INOCA.DesignA TweeSteden mild stenosis observational cohort study in patients with suspected INOCA as detected by ischaemic reason for referral and non-obstructive arteries based on coronary angiography or computed tomography.MethodsMedication documented in the hospital records of 488 patients (53% women) was coded as angina relief medication, blood-pressure-lowering medication, antithrombotics, statins, and non-cardiac medication, using the Anatomical Therapeutic Chemical code. Depressive symptoms and anxiety were recoded as 'consistent distress' (above the cut-off score for depression and anxiety on validated questionnaires), 'inconsistent distress' (above the cut-off for depression or anxiety) or 'no distress' (below the cut-off).ResultsNo sex differences were observed in cardiac medication use. Women used anxiolytic benzodiazepines more often (12% vs 4%, p = 0.002) compared to men. Consistent distress was more prevalent in women (22% vs 15%, p = 0.004) and was related to the use of more angiotensin-converting enzyme inhibitors/angiotensin receptor blockers and diuretics in women and to calcium antagonist use as well as lower adherence levels in men. Women who reported chest pain more often received angina relief medication and blood-pressure-lowering medication than men.ConclusionNo sex differences were observed in cardiac medication use in patients with suspected INOCA. Psychological distress may reflect hypertension and subsequent medication use in women, and experiencing chest pain and subsequent medication use in men.

Project description:BackgroundAs the understanding of the association between community-level education and dementia is insufficient, this study examined the contextual association of community-level prevalence of low educational attainment on the risk of dementia incidence. With this study, we further explored the potential differences in the aforementioned associations for urban and non-urban areas.MethodsWe analyzed 6 years of prospective cohort data from the Japan Gerontological Evaluation Study, beginning with the baseline data collected between 2010 and 2012, for 51,186 physically and cognitively independent individuals aged ≥65 years (23,785 men and 27,401 women) from 346 communities in 16 municipalities across 7 prefectures. We assessed dementia incidence using available data from the long-term care insurance system in Japan. We dichotomized education years as ≤9 and ≥ 10 years and aggregated individual-level educational attainment as a community-level independent variable. Model 1 covariates were age and sex. Income, residential years, disease, alcohol, smoking, social isolation, and population density were added in Model 2. We conducted multiple imputation to address the missing data. We performed a two-level (community and individual) survival analysis to calculate hazard ratios (HRs) and 95% confidence intervals (CIs).ResultsThe results indicate that the cumulative incidence of dementia during the follow-up period was 10.6%. The mean proportion with educational attainment of ≤9 years was 40.8% (range: 5.1-87.3%). Low community-level educational attainment was significantly associated with higher dementia incidence (HR: 1.04; 95% CI: 1.01-1.07), estimated by 10 percentage points of low educational attainment after adjusting for individual-level educational years and covariates. While the association was significant in non-urban areas (HR: 1.07; 1.02-1.13), there was no association in urban areas (HR: 1.03; 0.99-1.06).ConclusionsOlder people living in communities with low educational attainment among their age demographic develop dementia more often compared with those living in areas with high educational attainment after adjusting for individual-level educational attainment and covariates; the association was pronounced in non-urban areas. Securing education for adolescents as a life course and population approach could thus be crucial in preventing dementia later in life among older people living in non-urban areas.

Project description:We examine to what extent the effect of early-life conditions (health and socioeconomic status) on health in later life is mediated by educational attainment and life-course trajectories (fertility, partnership, employment).Using data from the Survey of Health, Ageing and Retirement in Europe (N = 12,034), we apply, separately by gender, multichannel sequence analysis and cluster analysis to obtain groups of similar family and employment histories. The KHB method is used to disentangle direct and indirect effects of early-life conditions on health.Early-life-conditions indirectly impact on health in later life as result of their influence on education and family and employment trajectories. For example, between 22% and 42% of the effect of low parental socio-economic status at childhood on the three considered health outcomes at older age is explained by educational attainment for women. Even higher percentages are found for men (35% - 57%). On the contrary, the positive effect of poor health at childhood on poor health at older ages is not significantly mediated by education and life-course trajectories. Education captures most of the mediating effect of parental socio-economic status. More specifically, between 66% and 75% of the indirect effect of low parental socio-economic status at childhood on the three considered health outcomes at older age is explained by educational attainment for women. Again, higher percentages are found for men (86% - 93%). Early-life conditions, especially socioeconomic status, influence family and employment trajectories indirectly through their impact on education. We also find a persistent direct impact of early-life conditions on health at older ages.Our findings demonstrate that early-life experiences influence education and life-course trajectories and health in later life, suggesting that public investments in children are expected to produce long lasting effects on people's lives throughout the different phases of their life-course.
