Sex differences in vision and hearing impairments across age and European regions : Findings from SHARE.

Abstract

Although sensory impairments are common conditions among older people, research often fails to consider the role of sex. We examined sex differences in vision impairment and hearing impairment across age and European regions. We conducted across-sectional study based on apooled sample of 65,656 females and 54,881 males aged 50years and older participating in the Survey of Health, Ageing and Retirement in Europe (SHARE) from 2004-2020. Logistic regression models with robust standard errors providing odds ratios (OR) and 95% confidence intervals (CI) were used to examine associations. European females had generally higher odds of vision impairment (OR 1.16, 95% CI 1.12-1.21) but lower odds of hearing impairment than European males (OR 0.70, 95% CI 0.67-0.73). The female disadvantage in vision increased with advancing age, whereas the female advantage in hearing decreased. No overall sex difference in vision was found in northern Europe, but females had more vision impairments than males in southern (OR 1.23, 95% CI 1.14-1.32), western (OR 1.14, 95% CI 1.08-1.21) and eastern (OR 1.10, 95% CI 1.02-1.20) Europe. Females were healthier than males in terms of hearing in all regions, with the largest female advantage in northern Europe (OR 0.58, 95% CI 0.53-0.64). Our findings demonstrate an overall consistent pattern of sex differences in sensory impairments across Europe showing an increasing female disadvantage in vision and adecreasing female advantage in hearing with advancing age.
