title: HIV-1 seroepidemiological profile in age groups and sexes in Benin City, Nigeria.
abstract: A pilot survey of 2,206 collected sera were screened for HIV-Ab by ELISA in the age groups 10-60 years. The age group 20-29 years recorded the highest HIV-1 Ab with 9/239 (3.77%). The age group 10-19, 30-39 and 40-49 recorded 3/192 (1.56%); 4/725 (0.55%) and 2/671 (0.3%), respectively. The age group > 50 years had 1/379 (0.26%). The relative rate was 3.29 between females and male with 95% confidence intervals of 1.33-8.14, p = 0.0125 by Fisher's Exact test. Conditioned on marital status, there was no significant difference in HIV-1 Ab distribution for the various age groups using modified Chi-square, G2 = 18.08 at [symbol: see text] = 0.01.
