Sexually active life expectancy

Sexually active life expectancy is the average number of years remaining for a person to be sexually active. This population-based indicator extends the concept of health expectancy to the measure of sexuality (via sexual activity). Calculation of sexually active life expectancy uses the age-specific prevalence data on sexual activity in conjunction with life table data on survival probabilities to partition the number of person-years into years with and without sexual activity, which is based on the Sullivan method.[1] The measure of sexually active life expectancy was introduced by Lindau and Gavrilova.[2][3][4]

A study of two large population-based U.S. surveys found that, on average, women expect fewer years of sexual activity, mainly due to prevalent widowhood among older women. This gender disparity is attenuated for people with a spouse or other intimate partner. The study also found that men tend to lose more years of sexually active life due to poor health.[4]

Sexually active life expectancy is an associated with self-reports of good health in both men and women. Sexuality has been identified as an important attribute to overall health and a marker of quality of life. Physicians may find that sexually active life expectancy can be used as an incentive for patients to become (and stay) healthy.[4]
