HIV in Women in an Aging Population: An Interview with Dr. Peggy McEvoy

From 1996 to 2001, Dr. Peggy McEvoy served as the Caribbean Team Leader for the United Nations Programme for HIV/AIDS (UNAIDS).  Dr. McEvoy completed undergraduate work in nursing at Columbia University.  She received a Master of Public Health from Tulane University before obtaining a Doctorate in Public Health from Columbia University.  She served in the Peace Corps in Togo and is fluent in Spanish, French, and English.  When AIDS was first identified in the early ‘80s, Dr. McEvoy was the Senior Associate for family planning for the Population Council and was working in Africa when some of the first women with HIV/AIDS started arriving in family planning clinics.

When McEvoy began her directorship of the Caribbean program in 1996, the region’s HIV epidemic mimicked the African outbreak.  Reported cases of HIV were divided evenly between men and women.  While in Africa the causes of such division lie in the sociocultural issues, the pattern commonly occurs in areas marked by homophobia in the Caribbean.  Families in this region encourage their sons to marry despite their homosexual or bisexual orientation.  Because these men continue to have relations with men, their wives are exposed to HIV. 

HIV is the leading cause of death and disease in women of reproductive age.  According to UNAIDS, in Sub-Saharan Africa, 60 percent of those living with HIV are women, and prevalence among young women aged 15-24 years is higher than among men of the same age.

Another source of infection worldwide is the need to exchange sex for food, money, shelter, or other necessities (transactional sex).  Transactional sex results in the spread of HIV worldwide.  “I have encouraged authorities in many countries to use “transactional sex” and not other terms like prostitution,” says McEvoy.  “When you find a little, eight year-old girl selling oranges at the border of Mali, she’s expected to bring home money.  If she doesn’t sell her oranges, she has sex with a truck driver for that money so as not to get beaten. That’s transactional.  That’s not prostitution.”

Safe sex promotion, the availability of male and female condoms, clean needle exchange programs for intravenous drug users, and HIV testing are important tools in managing the spread of HIV.  “While a test was available at the beginning of the HIV/AIDS outbreak, health systems, and infrastructure were not set up to cope with the problem,” Dr. McEvoy explained. 

Fear of stigmatization and exclusion prevented many individuals from seeking testing. Early testing required time that many individuals did not have; individuals needed to travel long distances to the healthcare facility to receive the test.  After the facility processed the test, the individual then needed to return to the clinic to receive the results. Presently, a buccal smear is available.  This quick test for HIV was initially only available in health clinics. Now, the FDA has approved these tests for home use, which will ensure much needed confidentiality. 

Older Adults
No published reports detail the incidence of HIV/AIDS in adults over the age of 49.  Now that the HIV/AIDS population is aging, researchers should seek epidemiologic information in this older age group, especially in the US and developed countries where services are available to support this population.

With the availability of erectile dysfunction medications, some older men have affairs with younger woman, infecting their wives with HIV.  Anecdotally, some individuals say that the biggest risk of infection for women is marriage.  In many countries married woman cannot negotiate condom use, regardless of whether or not their partner is promiscuous.  Women in polygamous relationships cannot refuse sex.

Campaigns to reduce the spread of HIV do not prioritize older populations.  The strongest emphasis is placed on woman and girls of reproductive age while no statistics exist for individuals over the age of 50. 

Future Steps and the Aging Population
Among safe sex promotion for seniors, prevention policies may emphasize the use of female condoms for older women.  Because female condoms are more lubricated than male condoms, older men who use Viagra may prefer these condoms. 

Researchers need to turn their attention toward this older age group, and nongovernmental organizations (NGOs) can contribute to these efforts.  Studies are needed to explore the prevalence of HIV in geriatric centers in the US, given the research indicating the spread of other sexually transmitted infections (STIs) in assisted living centers.  NGOs can facilitate this research by contacting universities and institutions to initiate the research on a small scale, utilizing individual skilled nursing facilities and assisted living centers.  This research would contribute to the body of knowledge and epidemiology of this disease.

  1. Interesting that you mention the lack of data on older people and HIV. This is a really serious issue that we at HelpAge International are working to raise awareness of. It is indeed not acceptable that statistics stop at age 49 when the epidemic is ageing across the world. Lack of data means lack of access to services and information for those who are affected by HIV and AIDS. We've produced an animation to highlight the impact of HIV on older women in Africa. Would love to hear your feedback!
