Although sensory impairments are common conditions among the elderly, research often fails to consider the role of sex. We examine sex differences in vision impairment (VI) and hearing impairment (HI) across age and European regions.
MethodsA cross-sectional study based on a pooled sample of 120,537 Europeans aged 50 + participating in the Survey of Health, Ageing and Retirement in Europe. Logistic regression models were used to examine associations.
ResultsGenerally, women reported more VI than men. This was the case for both close vision (OR 1.07, 95% CI 1.03; 1.11) and distant vision (OR 1.49, 95% CI 1.41; 1.57). Contrarily, women reported less HI than men (OR 0.71, 95% CI 0.68; 0.74). However, sex differences varied by age and regions. Sex differences in VI increased with advancing age, whereas the sex gap in HI decreased. For close vision, a female disadvantage was found from age 65 in Western, Southern and Eastern Europe and from age 80 + in Northern Europe. For distant vision, the female disadvantage was more pronounced and persisted in almost all age groups in the four regions. The female advantage in HI was found in all regions except for ages 80 + in Northern and Southern Europe. For dual sensory impairment (i.e., impaired vision and hearing), no overall sex difference was found, but a female advantage was demonstrated at ages 50-64 in all regions except Southern Europe.
ConclusionsOur ndings demonstrate an overall consistent pattern across Europe with a female disadvantage in vision but an advantage in hearing. SHARE is a multinational database containing data on various measures, such as health, socioeconomic factors, and social relations spanning across several countries among Europeans aged 50 years and older 18 . Since 2004, biennial survey waves have been conducted, and the database now contains data from eight waves, with the latest being conducted in 2020. Today, SHARE is representing 28 European countries and Israel 19 . SHARE is a longitudinal survey which, when possible, includes the same people in each wave, but to compensate for attrition and to maintain the younger age cohorts, refreshment samples are also drawn regularly 20 . SHARE data is collected according to strict quality standards and with ex-ante harmonised interviews 18 .
