HIV/sexual risk reduction interventions in China: a meta-analysis

Area of Science:

• Public Health
• Behavioral Science
• Epidemiology

Background:

• HIV/AIDS remains a significant global health challenge, necessitating effective risk reduction strategies.
• Interventions promoting sexual risk reduction are crucial in controlling HIV transmission.
• China has implemented various educational, psychosocial, and behavioral interventions to address HIV/sexual risk.

Purpose of the Study:

• To conduct a meta-analysis evaluating the efficacy of interventions in China aimed at promoting HIV/sexual risk reduction.
• To quantify the impact of these interventions on key outcome variables related to HIV prevention.

Main Methods:

• A meta-analysis of 26 intervention studies conducted in China.
• Calculation of mean weighted effect sizes for outcomes including condom use, HIV knowledge, and self-efficacy.
• Application of fixed and random effects models, with Q statistic for homogeneity and Q(b) for moderating analyses.

Main Results:

• Interventions successfully enhanced HIV knowledge (d=0.706), condom use knowledge (d=0.620), and attitudes toward people living with HIV/AIDS (PLWHA; d=0.625).
• Significant increases were observed in condom use with regular (d=0.477) and casual partners (d=0.444), general condom use (d=0.408), and condom use self-efficacy (d=0.584).
• Interventions incorporating formative research, process evaluation, peer leadership, and single follow-up demonstrated greater positive impacts (p<0.001).

Conclusions:

• Educational, psychosocial, and behavioral interventions are effective in promoting HIV/sexual risk reduction in China.
• Specific intervention characteristics, such as peer leadership and formative research, are associated with enhanced effectiveness.
• Findings provide evidence-based recommendations for optimizing HIV prevention programs in similar settings.
