Understanding HIV Testing Behavior Among Construction Workers in Guangxi, China: The Role of Knowledge and Risk Perception

This study examined HIV/AIDS knowledge, attitudes, and testing behaviors among construction workers in Guangxi province, China, with a focus on factors influencing testing uptake. Using a cross-sectional survey design, 1,050 workers were approached through randomized sampling at selected construction sites, yielding 916 valid responses (87%). Data were collected via structured, self-administered questionnaires covering demographics, HIV/AIDS knowledge, risk perception and testing history. Descriptive statistics and multivariate logistic regression were used for analysis. Results showed moderate overall HIV/AIDS knowledge, with misconceptions persisting regarding transmission routes. While 78% of participants expressed willingness to undergo HIV testing, only 38% had ever been tested. Higher HIV knowledge scores, greater perceived risk, and lower stigma were significantly associated with previous testing (p < 0.05). Workplace health promotion and exposure to HIV information through community health services were also positively correlated with testing uptake. Gender differences emerged, with male workers more likely to report previous testing than female workers. Findings suggest the need for targeted, stigma-reducing HIV education tailored to construction workers, increased accessibility of on-site testing, and integration of HIV awareness into occupational health programs. The results provide evidence to guide public health interventions aimed at improving HIV testing rates in high-risk, mobile labor populations.
