Introduction to current issues on HIV/AIDS in older adults

This issue addresses some of the complex and evolving mental health needs of older adults living with HIV.

By Timothy G. Heckman, PhD

Through 2012, more than 1.1 million Americans had been diagnosed with AIDS (CDC, 2012). Of these, 155,642 (13.8 percent) were 50 years of age or older at the time of their AIDS diagnosis. In 2009, the prevalence rate of persons living with a diagnosis of HIV infection who were 50-54 (568/100,000) or 55-59 years of age (409/100,000) actually exceeded that of persons living with HIV infection who were 30-34 years old (336/100,000; CDC, 2012). Because of continuing risky sexual behaviors in HIV-infected older adults (Illa et al., 2008; Lovejoy et al., 2008) and extended survival periods due to increasingly efficacious antiretroviral therapies and improved clinical care (Palella et al., 2006), it is anticipated that one out of every two people living with HIV/AIDS in the United States in 2015 will be 50 years of age or older (Justice, 2010).  

The growing number of older adults living with HIV/AIDS is not unique to the United States; indeed, it is an international dilemma. In Nanning, China, the proportion of people living with HIV/AIDS who were 50 or older increased from 16.5 percent in 2007 to 42.7 percent in 2011 (Liu, Lin, Xu, Chen, Shi & Morisky). In Madagascar, persons ≥ 50 account for 34.9 percent of all HIV infections in the country (Negin & Cumming, 2010). In Zambia, persons ≥ 50 account for 20.4 percent of all HIV infections (Negin & Cumming, 2010). Clearly, the “graying” of HIV knows no geographic boundaries. 

The mental health needs of older adults living with HIV/AIDS are multi-faceted and ever-evolving (Martin et al., 2008). HIV-positive older adults are five times more likely to experience depression than similarly-aged HIV-negative adults (Applebaum & Brennan, 2009). Kalichman et al. (2000) found that 27 percent of HIV-infected older adults had thought about suicide in the previous week. Grov et al. (2010) found that 39 percent of community-dwelling HIV-infected older adults exhibited symptoms of major depressive disorder. Elevated levels of depressive symptoms in HIV-infected older adults are troubling because of their associations with poor life quality, impaired daily functioning, increased frailty, poor engagement and retention in care, and a greater number of comorbid health conditions (Havlik et al., 2009; High et al., 2012; Negin et al., 2012).   

Compared to their younger counterparts, HIV-infected older adults have significantly lower CD4 cell counts, higher plasma viral loads at the time of their HIV-serostatus identification and a lower likelihood of survival after an AIDS diagnosis (CDC, 2011; Martin et al., 2008). HIV-infected older adults also have fewer social supports, lower rates of HIV-serostatus disclosure and experience a large number of AIDS-related bereavements (Emlet, 2006; Rabkin et al., 2004; Siegel et al., 1999). In light of the many psychosocial challenges that HIV-infected older adults experience, it is very troubling that HIV-infected older adults are less likely to seek treatment for psychological disorders (Zanjani et al., 2007). Moreover, there are currently no-age contextualized mental health interventions for HIV-infected older adults that promote clinically meaningful and sustained reductions is psychiatric symptoms.

This issue of the Psychology and AIDS Exchange Newsletter provides researchers, practitioners, policy makers and caregivers with an update on the biopsychosocial needs of persons aging with HIV. The current convention is to define HIV-infected older adults as persons living with HIV/AIDS who are 50 years of age or older. While there is nothing particularly remarkable about the age cutoff of 50 years, 50 years of age is used by many organizations  to classify adults as “older” (e.g., the World Health Organization and Centers for Disease Control and Prevention). Moreover, Egger et al. (2002) identified ≥ 50 years old as an independent prognostic factor affecting clinical progression to AIDS and death. Many articles in this issue use ≥ 50 years of age as the cutoff for older adults.

In the current issue, several prominent researchers and practitioners address fundamental issues central to the lives of older adults living with HIV/AIDS. Travis Lovejoy, PhD, summarizes the still scant literature on patterns and predictors of continued unsafe sex in HIV-infected older adults and addresses potential intervention approaches to reduce risky sex in this group. Charles Emlet, PhD, LCSW, ACSW, discusses how stigmas related to HIV and aging impact the lives of many HIV-infected older adults. Stephen Karpiak, PhD, summarizes the literature on rates of adherence to HIV medications in HIV-infected older adults and the plethora of factors that influence adherence in this group. Richard Havlik, MD, MPH, discusses an increasingly problematic issue that affects a large number of HIV-infected older adults; the prevalence and impact of comorbid health conditions, such as depression, cardiovascular heart disease, osteoarthritis and cancer. Finally, Miranda and colleagues discuss race-related disparities in HIV-associated neurocognitive disorders in older adults living with HIV/AIDS.
