The Canadian population is aging. It’s estimated that the percentage of seniors will almost double within the next 25 years, when one quarter of the population will be aged 65 or older. Canadians living with HIV are also aging. However, HIV and seniors aren’t something that we often talk about in the same sentence. But, given the facts, we should.
It’s estimated that today 12% of the close to 70,000 Canadians who have an HIV diagnosis are aged 50 and older and that this is expected to increase over the next decade by 20%. In the U.S., the numbers are even more dramatic, where it’s estimated that by the middle of this decade most individuals with HIV will be over 50 years old.
The reason for these increasing numbers is that, because of improved treatment options, HIV+ people are living longer. It’s also because, both in Canada and the U.S., adults over the age of 50 account for between 15% and 17% of new HIV diagnoses every year.
When discussing HIV and aging, it’s important to keep in mind that, while most HIVers in Canada are gay men and other men who have sex with men, a substantial percentage are women and heterosexual men and that aboriginal, African, Caribbean and black Canadians are heavily over-represented.
While older people are more likely than younger ones to present late for HIV testing and care and, for that reason, not uncommonly receive an AIDS diagnosis at the time they learn they’re HIV+, most older adults will have lived with HIV infection, and have been on antiretroviral (ARV) therapy for over 15 years. As these adults develop illnesses more commonly associated with aging than with HIV, they represent a unique challenge for their care providers. An HIV clinician, for example, may be very comfortable with the nuances of ARV therapy, but uncomfortable managing multiple age-related, but not necessarily HIV-related, illnesses. At the same time, these HIVers are typically too young to be seen by a geriatrician, who would be more comfortable with age-related illnesses but but less so with managing the complexities of HIV.
To address these issues, two organizations, one American, one Canadian, have recently published recommendations for treatment and management strategies in caring for older people living with HIV.
The American Academy of HIV Medicine (AAHIVM), which published its report in November 2011, provides best practice guidelines for HIV practitioners and other health care providers who treat, diagnose and refer older people with HIV. You can read the full report here, but as a non-medical man, two things stood out for me among the recommendations made.

The first was that primary care providers should perform routine, opt-out HIV screening in all adults, regardless of age or individual circumstances, because it’s very difficult to reliably estimate HIV risk in older people. This is already taking place in New York City and San Francisco, while the only jurisdiction in Canada that’s attempting something similar is Vancouver with its It’s Different Now project about which I wrote a couple of months ago here on PositiveLite.com.
The second thing that stood out for me in the American report was the recommendation to bypass the sometimes contentious federal treatment guidelines as to when to start ARV therapy. Those guidelines currently recommend that HIV+ people begin treatment when their CD4 cell count falls below the 500 cell mark. The AAHIVM is recommending, however, that ARV therapy should be considered for all HIV+ people over the age of 50, regardless of CD4 cell count. This is also the guideline currently used in British Columbia. (Canada has no national treatment guidelines of its own, although both Québec and B.C. have provincial ones, so many doctors in other Canadian provinces refer to the U.S. guidelines.)
The new Canadian report on HIV and aging is from the Canadian AIDS Society (CAS) and was published in May 2011. It covers a lot of ground from prevention to diagnosis, treatment and care, and incorporates background information and physiological and psychosocial considerations, before making its recommendations. It’s available to download here.
The CAS recommendations are more broad-ranging than the AAHIVM ones and are addressed not only to health care providers, AIDS service organizations, policy makers and researchers but also to ourselves as people living with HIV.
The report has some interesting things to say about HIV prevention among older people. It points out that because older adults haven’t generally been considered a vulnerable population, HIV prevention programs haven’t usually been targeted at this age group. For the most part, this population received little sexual health education when they were young and, as a result, many older adults may not be aware of HIV prevention methods and behaviours that put them at risk of infection.
In addition, because of agism, health care professionals and educators may assume that these older adults are not sexually active, leading to missed opportunities for education and screening for HIV and other STIs. Further, talking about sex may be considered a social taboo. Like many younger people, older adults may also intentionally hide their sexual orientation, extramarital sexual activity, involvement with sex workers and substance use. For these reasons, CAS is recommending that HIV prevention programming should recognize that older Canadians may be at risk of acquiring HIV.
It’s also recommending engaging older people already living with HIV within a framework that has a positive impact on their physical, mental, emotional and sexual health. This, in turn, would create an enabling environment that’ll reduce the likelihood of HIV transmission. This is a revised concept of “poz prevention” that CAS refers to as Positive Health, Dignity and Prevention.
Like the AAHIVM study referenced earlier, the CAS document recognizes that for older people living with HIV, appropriate care must take into account not only HIV-specific physiological and psychosocial effects but also the effects of aging and the co-morbidities that are associated with it.
CAS is concerned that as HIV+ Canadians get older and seek services outside HIV-specific care, they may find that services are not tailored to their needs and that they may experience greater stigma. For example, health care services that have been traditionally offered to older people (such as home care, rehabilitation, specialists) may not be accustomed to dealing with people who are HIV+, gay or who have a history of drug use. It may be a challenge to meet the care needs of older HIVers in this context, particularly in smaller communities, with the existence and access to services likely to vary across the country.

The report goes on to talk about the inter-related physiological factors that affect the health of older HIVers, including the effects of HIV itself and of ARV therapy on the body over time, the aging process, other health conditions associated with aging and lifestyle issues such as diet, smoking, alcohol and drug use, exercise and nutrition. It also recognizes that a range of social determinants of health play a key role in how HIV and aging affect Canadians, including housing, income support, employment, food security, racism, sexism, homophobia and social exclusion.
It also talks about the psychosocial effects of HIV and aging, which, much like the physiological effects, are closely inter-related. They may include depression, cognitive changes and coping with loss and anxiety. Many of these issues were addressed in some depth by educator Patty Solomon whom I interviewed for PositiveLite.com following a presentation she made at the 2011 Ontario HIV Treatment Network conference.
The conclusion I draw from reading these two reports is that there’s still so much we don’t know about older people who are living with HIV. But what both the AAHIVM and CAS show conclusively is that ensuring an appropriate response to the challenges of HIV and aging requires a range of stakeholders, including HIVers ourselves, to take action in a number of areas. Their recommendations in this regard are bold efforts to begin to help us to understand the needs of older HIVers and the kind of strategies that need to be implemented to meet them. As I said at the beginning of this article, talking about HIV and seniors is something that we need to do.
