- W77266568 abstract "Results of a Malawian study suggest that, contrary to usual practices, individuals aged 50 or older should not be routinely excluded from HIV (1) studies, as many of these individuals remain sexually active and at risk for HIV.; Although levels of sexual activity declined with age among study participants, a considerable proportion of 50-64-year-olds-84% of males and 50% of females--reported having had sex in the past year. Moreover, 9% of males and 5% of females aged 50-64 tested positive for HIV; although females in that age-group were less likely than 15-49-year-olds to have the virus (odds ratio, 0.5), males aged 50-64 were more likely than younger men to be HIV-positive (2.0). Most HIV studies and reproductive health programs in Sub-Saharan Africa have focused on persons aged 15-49, and relatively little is known about sexual activity and HIV risk among older individuals. The new study explored these issues using data from the Malawi Longitudinal Study of Families and Health, which has surveyed residents of three rural districts biennially since 1998. The original sample consisted of 1,541 ever-married women aged 15-49 and 1,065 of their spouses; the sample was expanded in 2004 by the addition of roughly 1,500 youth aged 15-24, and in 2008 by the addition of about 800 parents of study participants. The current analysis combined demographic and behavioral data from the 2010 survey with HIV data from 2008. Using both descriptive analyses and multivariate regression analyses that controlled for background characteristics, the researchers compared HIV prevalence, sexual behavior and HIV risk perceptions among men and women aged 15-49, 50-64 and 65 or older. In addition, they used nonparametric regression to examine outcomes and behaviors by age in greater detail. Of the 3,719 study participants who completed the 2010 survey, a third (310/c) were 50 or older, and 13% were 65 or older. The vast majority of men (87%) and women (77%) were married. About two-thirds of respondents had been tested for HIV in 2008. Among females, the overall prevalence of HIV was 7%, and the prevalence among women aged 50-64 (5%) was not significantly different from that among those aged 15-49 (8%). Among males, the prevalence was 5% overall, and was higher among men aged 50-64(9%) than among younger men (4%). In fact, males aged 50 or older accounted for 43% of HIV cases among men, even though they represented only 33% of the males tested; women aged 50 or older accounted for 16% of female HIV cases and 30% of the tested female sample. For both sexes, HIV prevalence was about 1% among respondents aged 65 or older. About 90% of men and women aged 1549 reported having had sex in the past year. Although the proportion declined with age, levels of sexual activity remained substantial. …" @default.
