BackgroundThe prevalence of self-injury and suicide is higher than the general population of people living with HIV/AIDS (PLWHA). However, the results reported in existing studies are highly variable in China. The purpose of this systematic review and meta-analysis was to synthesize the currently available high-quality evidence to explore the prevalence and influence factors of self-injury and suicide among PLWHA in China.MethodWe retrieve literature written in Chinese and English through databases such as PubMed, Embase, Web of Science, Cochrane Library, SinoMed, CNKI, WanFang Database, and CQVIP from inception to 1 September 2022. Sata 16.0 software was used for analysis.ResultsA total of 28 studies were included with a sample size of 1,433,971 and had a satisfactory quality score of ≥ 5. The prevalence among PLWHA in China were 30% for suicidal ideation (SI), 5% for suicide attempt (SA), 8% for suicide plan (SP), 7% for attempted suicide (AS), and 3‰ for completed suicide. High stigma (OR = 2.94, 95%CI: 1.90 − 4.57), depression (OR, 3.17; 95%CI, 2.20 − 4.57), anxiety (OR, 3.06; 95%CI, 2.23 − 4.20), low self-esteem (OR, 3.82, 95%CI, 2.22 − 6.57), high HIV related stress (OR, 2.53; 95%CI, 1.36 − 4.72), and unemployment (OR, 2.50; 95%CI, 1.51 − 4.15) are risk factors for SI; high social support (OR, 0.61; 95%CI, 0.44 − 0.84) and spouse infected with HIV (OR, 0.39; 95%CI, 0.21 − 0.74) are protective factors for SI; depression (OR, 1.62; 95%CI, 1.24 − 2.13), high aggression (OR, 4.66; 95%CI, 2.59 − 8.39), and more negative life events (OR, 2.51; 95%CI, 1.47 − 4.29) are risk factors for AS; high level of education (OR, 1.31; 95%CI, 1.21 − 1.43) is risk factor for CS.ConclusionFigures indicate that approximately one-third of PLWHA had suicidal ideation, and three out of 1,000 completed suicide in China. Positive events are protective factors for self-injury and suicide among PLWHA, while negative events are risk factors. This suggests that psychosocial support and risk assessment should be integrated into the care of PLWHA.
