Determinants of HIV/AIDS prevention and transmission knowledge factors among women aged 15-49: a trend analysis based on the Bangladesh Demographic and Health Survey
Keywords:
HIV/AIDS prevention knowledge, HIV/AIDS transmission knowledge, Bangladesh National Health SurveyAbstract
Background: The number of HIV/AIDS cases is increasing daily. It had risen by more than 300% in the last seven years (from 1,207 cases in 2007 to 3,674 in 2014). Knowledge is linked to HIV/AIDS prevention and transmission. This study aimed to assess the factors of HIV/AIDS prevention and transmission knowledge among Bangladeshi reproductive-aged women from 2007 to 2014. Methods: We conducted a retrospective cross-sectional comparison study based on secondary data from BDHS on knowledge of HIV/AIDS transmission and prevention methods. In the study, we included a total of 46,608 unweighted individuals, ever married women (15-49 years). Multinomial logistic regression was used to examine the effect of the explanatory variables on knowledge of HIV prevention and transmission. Results: The prevalence of knowledge about HIV/AIDS prevention and transmission methods displayed a trend of significant increase, but HIV/AIDS prevention methods knowledge was found to be lower than knowledge about transmission. The mean difference of HIV/AIDS transmission knowledge was 62% [ (95% of CI: 60%-64%), p-value <.001], whereas the mean difference of HIV/AIDS prevention methods knowledge was 50% [(95% of CI: 37%-63%), p-value .004]. For 2007, wealth index, region, highest education, and type of residence; for 2011, wealth index, highest education, and type of residence; and for 2014, age, marital status, wealth index, and highest education, respectively, were shown haves significant associations with knowledge status of HIV/AIDS prevention and transmission. Thus, the highest education and wealth index variables were found to be significant for the 2007-2014 period. Conclusion: HIV/AIDS prevention and transmission knowledge (medium and high status) were found to be in increment. In the Khulna region, the knowledge level was low. And in our study, another significant finding was the importance of education. In order to increase knowledge, the policy maker should organize HIV/AIDS-related health education programs with particular attention to the region and educational level of the people.
