Frequency of human immunodeficiency virus testing among rural US residents and why it is done

To examine the frequency with which rural residents' undergo human immunodeficiency virus (HIV) antibody testing and the reasons why.

Data are from the 1991 National Health Interview Survey's supplemental questions on knowledge and attitudes about acquired immunodeficiency syndrome.

The respondents were 42,725 adults (aged > or = 18 years), representing a nationwide sample of the civilian, noninstitutionalized population of the United States. Rural (n = 9903) and urban (n = 32,822) respondents were compared.

Although 7.1% of rural and 7.9% of urban respondents are at high risk for contracting HIV (P = .06), 25.2% of rural and 33.0% of urban respondents had been tested for HIV (P = .001). Excluding blood donations, 10.7% of rural and 17.2% of urban respondents had been tested for HIV (P = .001). The primary reason between the two groups for not getting tested was a belief of being at low risk for contracting HIV. Rural respondents were less likely than urban respondents (6.6% vs 10.4%) (P = .001) to be tested for HIV in the next 12 months. Rural respondents were less informed about HIV risks than were urban respondents. Urban residence is a significant predictor of having had an HIV test even after controlling for actual risk status, perceived risk status, age, education, income, sex, perceived health status, and a scale of knowledge of acquired immunodeficiency syndrome risk factors (odds ratio, 1.54; 95% confidence interval, 1.37 to 1.73).

Rural residents are less knowledgeable about HIV risk factors and are less likely to have been tested for HIV. With the increasing rates of infection in rural areas, specific and focused efforts for counseling and testing for HIV antibodies in rural areas might prevent and control HIV infection and acquired immunodeficiency syndrome.
