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.

Adult 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. In 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). People 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. Our 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.
