Sexual behavior in later life.

OBJECTIVE

This research tests the influences of age, biological, and psychosocial factors on sexual expression in later life.

METHOD

The American Association of Retired Persons Modern Maturity Sexuality Survey collected data on diagnosed illnesses, treated illnesses, sexual desire, sexual attitudes, partner circumstances, and sexual behavior from 1,384 persons ages 45 and older. Ordered logistic regression models estimate the associations of age, biological, and psychosocial factors with the frequency of five sexual behaviors.

RESULTS

Diagnosed illnesses and treatments are generally unrelated to frequency of sexual activity. Sexual attitudes are related to frequency of partnered behavior and sexual desire is related to frequency of masturbation among both women and men. Satisfaction with the physical relationship with a partner is strongly related to behavior. Age remains significant after all other factors are controlled.

DISCUSSION

The authors conclude that the nature of sexual expression in later life reflects the interplay of body, mind, and social context.
