Abstract
BACKGROUND: Sensory function declines with age and may impact sexual function in older adults. Indeed, the sense of smell plays a uniquely strong role in sexual motivation. Therefore, olfactory dysfunction in older adults may be intimately linked to changes in sexual desire and satisfaction. AIM: To test whether impaired olfactory function is associated with decreased sexual activity and motivation in older adults. METHODS: Cross-sectional analysis of a nationally representative sample of community-dwelling older U.S. adults from the National Social Life, Health, and Aging Project. OUTCOMES: 2 modalities of olfactory function were measured (sensitivity to n-butanol and odor identification) via validated methods (Sniffin' Sticks). Respondents answered survey questions about frequency of sexual thoughts (motivation) and sexual activity, and satisfaction with their most recent sexual relationship. A wide range of demographic, health, and social information were also collected. RESULTS: Decreased olfactory function in older U.S. adults was associated with decreased sexual motivation (odds ratio 0.93, P = .03) and less emotional satisfaction with sex (odds ratio 0.89, P = .04), but not decreased frequency of sexual activity or physical pleasure, in analyses that were adjusted for age, gender, race, education, cognition, comorbidities, and depression. CLINICAL IMPLICATIONS: Olfactory dysfunction may affect sexuality in older adults. Potentially treatable causes of sensory loss should be addressed by clinicians to improve quality of life. STRENGTHS & LIMITATIONS: These results rely on validated olfactory testing, detailed measures of sexual attitudes and behaviors, and extensive demographic, health, and social history in a nationally representative sample of older U.S. adults. Owing to the cross-sectional nature of these analyses, we cannot determine causality. CONCLUSIONS: Olfactory dysfunction in older U.S. adults is associated with decreased sexual motivation and emotional satisfaction, potentially due to evolutionarily-conserved neurological links between olfaction and sexuality.
