Summary Aim To examine the magnitude of sex differences in survival from the coronavirus disease 2019 (COVID-19) in Europe across age groups and regions. We hypothesized that men have a higher mortality than women at any given age but that sex differences will decrease with age as only the healthiest men survive to older ages. Methods We used population data from the Institut National D’Études Démographiques on cumulative deaths due to COVID-19 from February to June 2020 in 10 European regions: Denmark, Norway, Sweden, The Netherlands, England and Wales, France, Germany, Italy, Spain and Portugal. For each region, we calculated cumulative mortality rates stratified by age and sex and corresponding relative risks for men vs. women. Results The relative risk of dying from COVID-19 was higher for men than for women in almost all age groups in all regions. The overall relative risk ranged from 1.11 (95% confidence interval, CI 1.01–1.23) in Portugal to 1.54 (95% CI 1.49–1.58) in France. In most regions, sex differences increased until the ages of 60–69 years, but decreased thereafter with the smallest sex difference at age 80+ years. Conclusion Despite variability in data collection and time coverage among regions, the study showed an overall similar pattern of sex differences in COVID-19 mortality in Europe.

Women experience greater longevity than men, but have poorer health, although sex differences vary across health measures and geographical regions. We aim to examine sex differences in Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) over age across European regions in a cross-sectional setting including 51,292 men and 62,007 women aged 50+ from a pooled sample of waves 1 (2004-05) to 6 (2015) in the Survey of Health, Ageing and Retirement in Europe. ADL and IADL were dichotomized into no limitations and at least one limitation. Binomial regression models were used to estimate absolute and relative sex differences. Women had higher risk than men of ADL limitations (RR = 1.21, 95% CI 1.16; 1.27) and IADL limitations (RR = 1.54, 95% CI 1.48; 1.60), corresponding to risk differences of 1.3% and 5.7%, respectively. When we stratified by age groups and regions, sex differences in ADL were found in all age groups in Southern Europe, in the age groups 65-79 years and 80+ years in Western and Eastern Europe, and from the age of 80 in Northern Europe. For IADL, sex differences were found in all age groups in the four European regions, except from ages 50-64 in Eastern Europe. The absolute sex differences increased with age in all European regions. In conclusion, our results lend support for the male-female health survival paradox by showing that European women have higher risk of ADL and IADL limitations than European men, and that sex differences increase with advancing age.

Background Cross-national comparison studies on gender differences have mainly focussed on life expectancy, while less research has examined differences in health across countries. We aimed to investigate gender differences in cognitive function and grip strength over age and time across European regions. Methods We performed a cross-sectional study including 51 292 men and 62 007 women aged 50 + participating in the Survey of Health, Ageing and Retirement in Europe between 2004–05 and 2015. Linear regression models were used to examine associations. Results In general, women had better cognitive function than men, whereas men had higher grip strength measures. Sex differences were consistent over time, but decreased with age. Compared with men, women had higher cognitive scores at ages 50–59, corresponding to 0.17 SD (95% CI 0.14, 0.20) but slightly lower scores at ages 80–89 (0.08 SD, 95% CI 0.14, 0.00). For grip strength, the sex difference decreased from 18.8 kg (95% CI 18.5, 19.1) at ages 50–59 to 8.5 kg (95% CI 7.1, 9.9) at age 90 + . Northern Europeans had higher cognitive scores (19.6%) and grip strength measures (13.8%) than Southern Europeans. Gender differences in grip strength were similar across regions, whereas for cognitive function they varied considerably, with Southern Europe having a male advantage from ages 60–89. Conclusion Our results illustrate that gender differences in health depend on the selected health dimension and the age group studied, and emphasize the importance of considering regional differences in research on cognitive gender differences.

Recent research suggests that epidemiological forces in religion and health can have opposed effects. Using longitudinal data of people aged 50+ included in wave 1 (2004-2005) of the Survey of Health, Ageing and Retirement in Europe (SHARE), and followed up through waves 2 (2006-2007), 4 (2011) and 5 (2013), we examined two forms of religious internalization and their association with health. Multivariate logistic regressions were used to examine all associations. Taking part in a religious organization was associated with lower odds of GALI (global activity limitation index) (OR = 0.86, 95% CI 0.75, 0.98) and depressive symptoms 0.80 (95% CI 0.69, 0.93), whereas being religiously educated lowered odds of poor self-rated health (SRH) 0.81 (95% CI 0.70, 0.93) and long-term health problems 0.84 (95% CI 0.74, 0.95). The more religious had lower odds of limitations with activities of daily living 0.76 (95% CI 0.58, 0.99) and depressive symptoms 0.77 (95% CI 0.64, 0.92) than other respondents, and compared to people who only prayed and did not have organizational involvement, they had lower odds of poor SRH 0.71 (95% CI 0.52, 0.97) and depressive symptoms 0.66 (95% CI 0.50, 0.87). Conversely, people who only prayed had higher odds of depressive symptoms than non-religious people 1.46 (95% CI 1.15, 1.86). Our findings suggest two types of religiousness: 1. Restful religiousness (praying, taking part in a religious organization and being religiously educated), which is associated with good health, and 2. Crisis religiousness (praying without other religious activities), which is associated with poor health.

Objectives-To examine sex differences in prevalent comorbidity and frailty across age and European regions. Methods-This is a cross-sectional study based on 113,299 Europeans aged 50? participating in the Survey of Health, Ageing and Retirement in Europe from 2004-2005 to 2015. Sex differences in the Comorbidity Index and the Frailty Phenotype were investigated using ordinal logistic regressions. Results-European women had generally higher odds of prevalent comorbidity (OR 1.11, 95% CI 1.07-1.15) and frailty (OR 1.56, 95% CI 1.51-1.62). Sex differences increased with advancing age. No overall sex difference in comorbidity was found in Western Europe, but women had more comorbidity than men in Eastern (OR 1.30, 95% CI 1.18-1.44), Southern (OR 1.23, 95% CI 1.15-1.30), and Northern (OR 1.08, 95% CI 1.01-1.16) Europe. Women were frailer than men in all regions, with the largest sex difference in Southern Europe (OR 1.84, 95% CI 1.72-1.96).

BackgroundAdult mortality has been postponed over time to increasingly high ages. However, evidence on past and current health trends has been mixed, and little is known about European disability trends.MethodsIn a cross-sectional setting, we compared cognitive and physical functioning in same-aged Europeans aged 50+ between 2004–05 (wave 1; n = 18 757) and 2013 (wave 5 refresher respondents; n = 16 696), sourced from the Survey of Health, Ageing and Retirement in Europe (SHARE).ResultsPeople in 2013 had better cognitive function compared with same-aged persons in 2004–05, with an average difference of approximately one-third standard deviation. The same level of cognitive function in 2004–05 at age 50 was found in 2013 for people who were 8 years older. There was an improvement in cognitive function in all European regions. Mean grip strength showed an improvement in Northern Europe of 1.00 kg [95% confidence interval (CI) 0.65; 1.35] and in Southern Europe of 1.68 kg (95% CI 1.14; 2.22), whereas a decrease was found in Central Europe (-0.80 kg; 95% CI −1.16; −0.44). We found no overall differences in activities of daily living (ADL), but small improvements in instrumental activities of daily living (IADL) in Northern and Southern Europe, with an improvement in both ADL and IADL from age 70 in Northern Europe.ConclusionsOur results indicate that later-born Europeans have substantially better cognitive functioning than earlier-born cohorts. For physical functioning, improvements were less clear, but for Northern Europe there was an improvement in ADL and IADL in the oldest age groups.

Objectives: Religiousness is associated with longevity and better physical health, which may be due to lifestyle choices. Here we examine associations between religiousness and health, explained by lifestyle. Study design: Longitudinal study Methods: Data came from 23,864 people aged 50+ included in the Survey of Health, Ageing and Retirement in Europe (SHARE) in 2004-05 and followed up during 11 years. Results: Praying and taking part in a religious organization were associated with lower odds of smoking (OR = 0.

A scientific interest in opposite-sex (OS) twins comes from animal studies showing hormone transfer between fetuses in utero. A parallel effect in humans may occur, especially for OS females who may be exposed to androgens, in particular testosterone, from the male co-twin. Conversely, OS males may be exposed to lower levels of prenatal testosterone than do same-sex (SS) males. In this special issue, we reviewed published studies investigating potential differences between OS and SS twins in physiological, cognitive and behavioral traits focusing on the Twin Testosterone Transfer (TTT) hypothesis. Sixty articles fulfilled the eligibility criteria including 23 studies published since the review by Tapp et al. (2011). In general, studies of cognition are conflicting, but it is the phenotype for which most support for the TTT hypothesis is found. Less consistent evidence has been found regarding physiological and behavioral traits. We hope that this special issue will stimulate a discussion about how an investigation of the TTT hypothesis should continue in future research.
