Abstract

National estimates of HIV prevalence of the whole adult population are based on ANC based sentinel surveillance system. Therefore with the objective of determining the representativeness of the ANC attendees in relation to pregnant women not attending ANC and general adult population, a cross sectional comparative study was conducted. It employed a pre-tested standardized questionnaire to collect information on risk factors related to HIV/AIDS from a sample of 1426 individuals. Data was collected in Addis Ababa on April 2000 at the four health centers where the sentinel surveillance is ongoing and at the respective catchment’s areas of the health centers. Forty seven percent of the attendees belonged to the age group 15 - 24, 72% were unemployed, 33% had a monthly income of 500 Birr or more, 36% were new comers to the community and 89% were married. Although 61% were multipara, 50% had no children. Over 52% married at age below 19 years, 83.6% never used condom. There were no significant difference in risk profile between ANC attendees and the non-attendees pregnant women while there were significant differences among ANC attendees and the general adult population of females. ANC attendees were younger with low education; unemployed (72%), new comers to the area, and married compared to the general population of females. Majority of ANC attendees never used condom with regular and non-regular partners (92.7% and 77.6% respectively) and reported STI was 16.4%. Males were found to have significant association with risk factors i.e. majority of them were single (71.4%), had sexual intercourse with high risk partner (55%) with only 33% of every time use of condom with such partners. The related risk factors were observed to distribute significantly between ANC attendees and the GP of males showing both to have a high-risk profile. It was then concluded that ANC attendees can confidently be taken as representative of the general pregnant population and the GP of males, differ significantly with the general population of female who were observed to exhibit a low risk profile. In addition, close to 30% sexually inactive respondents in the GP, 52% never pregnant and 55% childless women were observed, an addition of another sentinel population as an adjunct to the existing one in order to capture these population is recommended.
