Abstract

Previous serosurveys of antibody to HIV-1 among incoming male inmates in Maryland between April and June of 1985, 1986 and 1987 have shown a prevalence of 7.0, 7.7 and 7.0%, respectively, with stability persisting after multivariate adjustment. To investigate seasonality and update annual trends, excess sera were obtained from incoming male inmates between August 1987 and August 1988. Correctional personnel also provided demographic variables of age, race, offense, category, and jurisdiction. Once rendered anonymous, specimens were assayed for antibody to HIV-1 using enzyme-linked immunosorbent assay and Western blot. For the 12-month study period, 415 (7.9%) of 5262 consecutive male entrants were seropositive. On univariate and multivariate analyses, no significant change in seroprevalence or risk by subgroup was noted by month or season. For data from April to June 1988, 113 (8.1%) of 1398 consecutive entrants demonstrated anti-HIV-1; seropositivity was associated with age > 25 years, Black race, and Baltimore jurisdiction. No significant change was found over time in seroprevalence or risk of HIV-1 infection by subgroup in multivariate analysis combining data for 1985-1988. These data provide additional evidence to suggest stability of HIV-1 seroprevalence in Maryland male prison entrants.
