Abstract
While studies on human immunodeficiency virus self-testing (HIVST) continue to accumulate after the World Health Organization’s recommendation of HIVST as an additional approach to HIV testing services in 2016, few studies have focused on men who have sex with men (MSM) in Chinese cities. A cross-sectional study was conducted to describe the HIVST status of MSM in Chongqing, China. MSM participants were recruited by random sampling, and qualified interviewers collected data, using confidential self-administered questionnaires. Blood specimens were collected for HIV antibody detection. The survey evaluated the uptake and accuracy of HIVST kits and identified factors that may be associated with HIVST. The proportion of HIVST uptake was 15.6%. The sensitivity and specificity of HIVST were 74.2% (95% confidence interval [CI] 66.6%–80.7%) and 99.0% (95% CI 96.9%–99.7%), respectively. The consistency between the HIVST kit and antibody detection results was 90.5% (95% CI 87.5%–93.0%), and the Kappa value was 0.777 (p < 0.001). The positive predictive value of self-testing kits is 80.9% and the negative predictive value is 17.7%. Having been tested ≥2 times in the last year, higher educational levels, and higher scores of basic HIV/AIDS knowledge facilitated higher uptake of HIVST. Self-reported existing barriers for HIVST uptake included older age, marital status, and having resided in Chongqing for more than two years.
Highlights
Despite global efforts to control human immunodeficiency virus (HIV) among crucial populations, new infections have continuously increased among men who have sex with men (MSM), among whom, the highest incidence, prevalence, and percentage rates of undiagnosed HIV infections are often detected [1,2]
Binary logistic regression revealed that age, highest level of education, marital status, scores of basic HIV/AIDS knowledge, number of HIV tests conducted in the last year, and duration of residing in Chongqing were significant independent predictors of HIV self-testing (HIVST) uptake among MSM
Our findings show that the significant determinants of HIVST uptake among MSM include age, highest level of education, marital status, basic HIV/AIDS knowledge, number of HIV tests conducted in the last year, and duration of residing in Chongqing
Summary
Despite global efforts to control human immunodeficiency virus (HIV) among crucial populations, new infections have continuously increased among men who have sex with men (MSM), among whom, the highest incidence, prevalence, and percentage rates of undiagnosed HIV infections are often detected [1,2].
