Old age alone no deterrent to active sex life

Barring ill health, many older adults maintain an active sex life, often into their 80s, according to results of a national survey published in The New England Journal of Medicine.

Furthermore, among respondents who were sexually active, the frequency of sexual activity was comparable to that reported among adults 18 to 59 years of age, lead author Dr. Stacy Tessler Lindau, from the University of Chicago, and co-investigators found.

However, ill health and lack of an intimate relationship are major impediments to sexual activity among individuals as they grow older.

"There is a void of information regarding changes in sexuality as we age," Lindau said in a teleconference with reporters. As a result, she added, physicians are hampered in their efforts to counsel patients about how their health care decisions will affect their sex lives.

To fill that void, Lindau's group designed the National Social Life, Health, and Aging Project to gather "comprehensive, nationally representative...data" about health and sexual behavior among older adults.

Professional interviewers spoke with 3,005 U.S. residents (1,550 women and 1,455 men), ages 57 to 85, asking them if they had engaged in vaginal intercourse, oral sex, and masturbation over the previous 12 months.

The investigators observed "high (agreement) between partners...in terms of the frequency of their sexual activity, both for vaginal intercourse and oral sex," providing validity to their analysis of survey responses.

Survey results showed that 73 percent of respondents aged 57 to 64 years of age were sexually active, as were 53 percent of those 65 to 74 years old, and 26 percent of those 75 to 85 years old.

Nevertheless, even in the oldest age group, 54 percent of those who were sexually active reported having sex at least two or three times per month, a frequency comparable to that documented in a similar survey among younger adults.

"The frequency of sex does not change a lot across age groups," Lindau said.

About half of the men and a quarter of the women reported masturbating in the previous year. As in the other sexual behaviors, the frequency of masturbation declined as people aged, primarily because of ill health.

Women were less likely than men to be sexually active, "because of physical problems of their partner, their own lack of interest, or lack of opportunity," co-author Dr. Linda Waite, also from the University of Chicago, said during the conference.

The disparity is related to men often having younger sexual partners, Waite added. "Women usually spend their final years as widows, while men tend to be married when they die."

The survey was not designed to identify sexual orientation, Lindau told Reuters Health. Even so, "we asked about the gender of their sex partner in the past 12 months," and three men and five women reported relationships with people of the same sex.
