HIV/AIDS knowledge, attitudes and beliefs based prediction models for practices in prison inmates, Sindh, Pakistan

This study was conducted on prison inmates in Sindh to determine whether HIV/AIDS related knowledge, attitudes and beliefs can predict their practices which risk HIV infection. A pre-designed questionnaire was administered in this cross-sectional study to collect the data on HIV/AIDS related knowledge, attitudes, beliefs, practices and demographic variables in a systematic sample of 3,395 prison inmates during July 1994. The data on responses of inmates to HIV/AIDS related knowledge, attitudes, and beliefs were analyzed and a clear interpretable factor structure emerged for each set of questions labeled as knowledge, attitude and beliefs. Similarly based on responses of inmates to practice questions, three factors emerged and were labeled as heterosexuality, homosexuality and drugs. The standardized factor scores of inmates for each of these six factors were computed and used in further analyses. Multiple linear regression analyses were carried out separately using heterosexuality, homosexuality and drugs factors score as dependent variables to identify if any of the independent variables (demographic variables, knowledge beliefs and attitude) predict these practice factors. The model for heterosexuality explained 23% of the variance and included HIV/AIDS related knowledge, beliefs, age, ethnicity and marital status and duration of imprisonment (F = 84.33, p < 0.001; R2= 23.0). The predictors in the model for homosexuality together explained 10% of the variance and included significant contribution by belief, martial status, ethnicity, education, age and duration of imprisonment (F = 24.76, p < 0.001; R2= 0.10). The model for drugs had significant contributions from HIV/AIDS related beliefs, marital status and ethnicity (F = 20.10, p < 0.001; R2= 0.03). Implications of prevention program based on these results are considered.
