The prevalence of HIV in Madagascar has been slowly rising in the past decade but in 1999 was still less than 0.5%.1 Although this rate is low compared with the rates in many other countries, including the United States (0.61%) and especially sub-Saharan African nations such as Zimbabwe (25%) and South Africa (20%),1 the risk factors for an epidemic are present. High rates of syphilis,2 hepatitis B virus,3 and other sexually transmitted diseases, as well as extreme poverty,4 suggest that many of Madagascars 14 million people are at risk for acquiring HIV. The AIDS Impact Model projected that HIV seroprevalence could reach 15% by 2015 if Madagascar follows the epidemic trend of countries like Kenya.5 We sought to determine directly whether high-risk behaviors that might lead to rising infection rates were present in this population. The aims of this study were to (1) determine a baseline level of public awareness and knowledge about HIV and AIDS and (2) ascertain the HIV and AIDS riskrelated behaviors of a segment of the general population in the capital city, Antananarivo.
During July and August 2000, we conducted 134 interviews with patients and visitors in the 2 teaching hospitals of the University of Antananarivo School of Medicine. All interviews used a 3-part, 41-item questionnaire eliciting information about demographics and previous sources of HIV and AIDS knowledge, an assessment of this knowledge, and a detailed personal history of HIV and AIDS riskrelated behaviors. The questionnaire, written in French, was translated for patients who spoke only Malagasy. The same American medical student and at least 1 Malagasy medical student or resident conducted each interview. Patients and visitors were eligible for participation if they were 18 years of age or older and could ambulate to a private room. We performed frequency calculations, t tests, analysis of variance tests, and Spearman rank correlation tests with SPSS, Version 10.0 (SPSS Inc, Chicago, Ill).
Demographics One hundred thirty-six people participated in the informed consent process, after which 2 people declined to participate and 2 other participants completed only the demographics and HIV and AIDS knowledge sections. Of the 134 participants, 71 (53%) were women. The participants median age was 33.5 years; 90 (67%) had completed high school. Ninety (67%) were married, and 32 (24%) lived in rural areas. Every participant had previously received HIV and AIDS information, most commonly from radio (118, 88%), but only 23 (17%) had received it from a health care provider.
HIV and AIDS Knowledge
Personal History One hundred thirty-two participants completed the personal history section (Table 2
HIV Knowledge and Demographic Correlations Education level was not associated with the number of questions answered correctly on the risk assessment test (P = .350), but age correlated significantly with test scores, with younger participants performing better (r = -0.264, P = .002). No significant difference was found in the mean test scores of men and women (P = .350) or of participants from rural or urban areas (P = .723). There was a trend toward better scores in participants who had previously spoken with health care workers about HIV or AIDS (P = .071).
The data from the HIV knowledge assessment suggest that HIV and AIDS awareness is high in Antananarivo, but knowledge of how HIV and AIDS cannot be transmitted and the use of condoms in prevention are limited. Understanding how HIV is not transmitted is important for preventing stigma against individuals with HIV and AIDS.6 Fear of stigma is known to deter citizens from being tested for HIV,7,8 an important opportunity for HIV and AIDS prevention counseling.9 The rate of multiple partnering among Malagasy men in this study was similar to World Health Organization reported rates in Uganda, Kenya, and Zimbabwe, whereas reported condom use rates in this study were much lower than the rates in these subSaharan African nations.1 The 2 potential protective factors found in this study were minimal travel to mainland Africa and the lower reported number of sexual partners for persons with multiple partners.
In this hospital-based survey, sexual activity could have been less than participants would normally report because of personal or family illness. Although every effort was made to make participants feel comfortable, rates of same-sex sexual relations and multiple partnering could have been underreported because of sensitivity and social stigma. Antananarivo is not representative of all of Madagascar, as indicated by higher education levels67% of the study participants had completed high school in a country where 12% start high school6and by higher rural hepatitis B virus prevalence.3
In this initial survey of the HIV and AIDS awareness, knowledge, and related behavior in Antananarivo, Madagascar, we observed that HIV and AIDS awareness is high, but knowledge about transmission is incomplete. High rates of multiple partnering and low condom use rates among people with multiple partners suggest that Madagascar is at risk for an epidemic. Intervention by health care workers, the Malagasy government, and nongovernmental organizations is warranted to prevent the disastrously high AIDS rates seen in Madagascars neighbors. A larger study that pairs HIV- and AIDSrelated knowledge and behavior surveying with HIV testing and includes participants from other parts of the country is needed to confirm these findings and to develop specific and effective surveillance and prevention programs.
This project was solely funded by a Patricia S. Levinson Fellowship through the Mount Sinai School of Medicine. These data were previously presented in a poster presentation at the International Health Medical Education Consortiums February 2001 conference in San Pedro Sula, Honduras. The authors would like to thank the Malagasy medical student association REMEDE for its essential translating aid and Karen Hamilton and Ilene Wilets for their academic support. We also thank the Faculty of Medicine of the University of Antananarivo and Patricia S. Levinson for their support of this project. Human Participant Protection This study, questionnaire, and consent forms were approved by the Mount Sinai Hospital Institutional Review Board and by the president of CHUA Hopital Joseph Ravoahangy Andrianavalona and the Laboratoire National de Reference VIH/SIDA prior to the start of the study.
