WHO NEUROPSYCHIATRIC AIDS STUDY, CROSS-SECTIONAL PHASE-I - STUDY DESIGN AND PSYCHIATRIC FINDINGS

Background: Most available studies on the psychiatric, neuropsychological, and neurological complications of HIV-1 infection and AIDS have been conducted in Western countries, on samples of well-educated, mostly white, homosexual men. Concerns about generalizability of the results of those investigations prompted the WHO to implement the cross-cultural venture called WHO Neuro psychiatric AIDS study. Methods: This project aims to assess the prevalence and natural history of HIV-1-associated psychiatric, neuropsychological, and neurological abnormalities in representative subject samples enrolled in the five geographic areas predominantly affected by the HIV-1 epidemic. Assessment is made by a data collection instrument including six modules. The intercenter and intracenter reliability in the use of each module has been formally evaluated. The study consists of a cross-sectional phase and a longitudinal follow-up. Results: The cross-sectional phase was completed in five centers. This paper reports on the results of psychiatric assessment, which revealed a significantly higher prevalence of current mental disorders Ln symptomatic seropositive persons compared with seronegative controls among intravenous drug users in Bangkok and homosexuals/bisexuals in Sao Paulo. The mean global score on the Montgomery-Asberg Depression Rating Scale was significantly higher in symptomatic seropositive individuals than in matched seronegative controls in all centers. Conclusions: These results suggest that the significance of the psychopathological complications of symptomatic HIV-1 infection may have been underestimated by previous studies conducted on self-selected samples of well educated, middle-class, mostly white, homosexual men.WHO, GLOBAL PROGRAMME AIDS, CH-1211 GENEVA, SWITZERLANDUNIV NAPLES, DEPT PSYCHIAT 1, NAPLES, ITALYCTR DIS CONTROL, DIV HIV AIDS, ATLANTA, GA 30333 USAMAX PLANCK INST PSYCHIAT, W-8000 MUNICH, GERMANYUNIV CALIF LOS ANGELES, INST NEUROPSYCHIAT, LOS ANGELES, CA USACHULALONGKORN UNIV, DEPT PSYCHIAT, BANGKOK, THAILANDUNIV KINSHASA, CTR NEUROPSYCHOPATHOL, KINSHASA, ZAIREUNIV MUNICH, DEPT PSYCHIAT, W-8000 MUNICH, GERMANYUNIV NAIROBI, DEPT PSYCHIAT, NAIROBI, KENYAESCOLA PAULISTA MED, DEPT PSYCHOBIOL, SAO PAULO, SP, BRAZILPROJET SIDA, KINSHASA, ZAIREESCOLA PAULISTA MED, DEPT PSYCHOBIOL, SAO PAULO, SP, BRAZILWeb of Scienc
