Abstract
Objectives. Using a life course approach, we examine how sexuality is related to risk of cognitive impairment for partnered older adults.
Methods. We utilized longitudinal data from two rounds of the National Social Life, Health, and Aging Project (NSHAP) to analyze 1,718 respondents. Cognition was categorized into three groups: normal, mild cognitive impairment, and dementia. We considered both sexual activity (i.e., being sexually active, sexual frequency) and sexual quality (i.e., physical pleasure, emotional satisfaction). We estimated cross-lagged models to test the potential reciprocal relationship between sexuality and cognitive impairment.
Results. Results from the total sample indicate that only emotional satisfaction with sex was related to later lower risk of cognitive impairment. Further tests by age group show that for adults aged 62-74, better sexual quality was related to a lower risk of cognitive impairment...
