Sexual Orientation and Functional Limitations: Cross-sectional Analyses From the Adult Psychiatric Morbidity Survey

Abstract

Objective: To assess the association between sexual orientation and functional limitations in a large representative sample of the English population.

Design: Cross-sectional.

Setting: Data were from the 2007 Adult Psychiatric Morbidity Survey.

Participants: A total of 7403 adults aged 16-95 years (51.4% female; mean age, 46.3±18.6y) were included in the present study.

Interventions: Not applicable.

Main outcome measures: Sexual orientation was assessed using 2 items adapted from the Kinsey scale and was dichotomized into heterosexual and sexual minority orientation. Functional limitations were assessed using 7 activities of daily living (ADL) and instrumental activities of daily living (IADL). Functional limitations were defined as at least 1 difficulty in 1 of 7 ADL and IADL. Adjusted logistic regression analyses were conducted to investigate the association between sexual orientation (independent variable) and functional limitations (dependent variable).

Results: The level of sexual minority orientation and prevalence of functional limitations in the sample was 7.1% and 32.9%, respectively. After adjusting for several potential confounders, sexual minority orientation was positively and significantly associated with functional limitations (odds ratio, 1.51; 95% confidence interval, 1.18-1.95; reference group: heterosexual orientation).

Conclusions: Based on the findings of this study, interventions aiming to prevent against and/or manage/reduce functional limitations in sexual minorities are needed. More research is also warranted to better understand mediators (eg, obesity, cognitive complaints, psychiatric disorders) involved in the sexual orientation-functional limitation relationship.
