Abstract

In Zimbabwe around 1.1 million children have been orphaned due to AIDS. We conducted a survey among school-attending youth in rural south-eastern Zimbabwe in 2003, and examined the association between orphaning and risk of HIV. We enrolled 30 communities in three provinces. All students attending Year 2 of secondary school were eligible. Each completed a questionnaire and provided a finger-prick blood specimen for testing for HIV-1 and HSV-2 antibodies. Female participants were tested for pregnancy. Six thousand seven hundred and ninety-one participants were recruited (87% of eligible); 35% had lost one or both parents (20% of participants had lost their father; 6% their mother; and 9% both parents). Orphans were not poorer than non-orphans based on reported access to income, household structure and ownership of assets. There was strong evidence that orphans, and particularly those who had lost both parents, were at increased sexual risk, being more likely to have experienced early sexual debut; to have been forced to have sex; and less likely to have used condoms. Fifty-one students were HIV positive (0.75%). Orphans were three times more likely to be HIV infected than non-orphans (adjusted odds ratio = 3.4; 95% confidence interval: 1.8-6.6). Over 60% of those HIV positive were orphaned. Among school-going youth, the rates of orphaning were very high; there was a strong association between orphaning and increased risk of HIV, and evidence of greater sexual risk taking among orphans. It is essential that we understand the mechanisms by which orphaned children are at increased risk of HIV in order to target prevention and support appropriately.
