HIV Prevalence Among Hospitalized Patients at the Main Psychiatric Referral Hospital in Botswana.

We examined HIV prevalence among patients 18-49 year olds admitted to a psychiatric hospital in Botswana in 2011 and 2012. The retrospective study analyzed females (F) and males (M) separately, comparing proportions with Chi square test and continuous variables with Wilcoxon rank-sum test, assessing significance at the 5% level. HIV seroprevalence among hospitalized psychiatric patients was much more common among females (53%) compared with males (19%) (p < 0.001). These women also appeared more vulnerable to infection compared with females in the general population (29%) (p < 0.017). Among both women and men, HIV-infection appeared most common among patients with organic mental disorders (F:68%, M:41%) and neurotic, stress related and somatoform disorders (F:68%, M:42%). The largest proportion of HIV infections co-occurred among patients diagnosed with schizophrenia, schizotypal and other psychotic disorders (F:48%; M:55%), mood (affective) disorders (F:21%; M:16%) and neurotic, stress-related and somatoform disorders (F:16%; M:20%). Interventions addressing both mental health and HIV among women and men require development.
