Socioeconomic inequality and contributors in accepting attitudes toward people living with HIV among adults in Ethiopia from 2005 to 2016: a population-based cross-sectional study

INTRODUCTION: The public's accepting attitude toward people living with HIV is crucial in reducing HIV-related stigma and discrimination, increasing people's access to HIV service. This study examines the inequalities in accepting attitudes toward people living with HIV in Ethiopia from 2005 to 2016. METHODS: This cross-sectional study was based on the 2005, 2011 and 2016 Ethiopian Demographic Health Surveys. A total of 17 075, 28 478 and 25 542 adults were included in the 2005, 2011 and 2016 surveys, respectively. Socioeconomic inequality was investigated using the concentration curve and Erreygers' concentration index (ECI), which is scaled from -1 (pro-poor) to +1 (pro-rich). The ECI was decomposed to identify the contributors to socioeconomic inequality using generalised linear regression with the logit link function. RESULTS: Accepting attitude toward people living with HIV was 17.9% (95% CI: 16.6%, 19.3%) in 2005, which increased to 33.5% (95% CI: 31.8%, 35.3%) in 2011 and 39.6% (95% CI: 37.6%, 41.9%) in 2016. ECI was 0.342 (p<0.001), 0.436 (p<0.001) and 0.388 (p<0.001), respectively, for 2005, 2011 and 2016. The trend line illustrates socioeconomic inequality seems diverging over time, with an increasing ECI of 0.005 every year (r=0.53; p=0.642; slope=0.005). CONCLUSIONS: The current study found that there was pro-rich inequality from 2005 to 2016. People with higher socioeconomic status had a better attitude toward people living with HIV. Comprehensive knowledge about HIV/AIDS, education status, residence, and access to electronic and paper-based media, as well as HIV testing, contribute to a better accepting attitude toward people living with HIV. It is of utmost importance for the country to enhance accepting attitude toward people living with HIV to reduce stigma and discrimination. This requires whole-system response according to the primary healthcare approach toward ending the epidemic of HIV/AIDS in the country.
