Influence factors associated with fertility intention among people living with HIV in China and other regions: a systematic review and meta-analysis.

Background: Advances in medical care and improved quality of life have fostered a growing desire for parenthood among people living with HIV (PLHIV). However, this desire remains inadequately addressed in China, highlighting a crucial research gap. Understanding the factors influencing fertility intentions in PLHIV is essential for informing policy development.

Methods: We conducted a systematic review of English and Chinese literature, analyzing articles from 2000 to 2024. The odds ratio (OR) with 95% confidence intervals (CIs) was used for pooled measurement. Subgroup analyses based on regional factors were performed, and publication bias was assessed using Egger's test.

Results: The review included 25 articles with 11,394 participants. Key factors associated with fertility intention included age (OR = 2.67, 95%CI: 2.04-3.48, P < 0.05), marital status (OR = 1.52, 95%CI: 1.14-2.02, P < 0.05), and number of children (OR = 5.28, 95%CI: 3.58-7.79, P < 0.05). Interestingly, education level did not significantly impact fertility desire (OR = 1.08, 95%CI: 0.72-1.41, P = 0.61). Subgroup analysis revealed that childlessness was a stronger influence in China (OR = 7.40, 95%CI: 3.76-14.58, P < 0.05) compared to developing and developed countries, where higher education levels had minimal or even negative effects on fertility intentions (OR = 0.98, 95%CI: 0.66-1.46, P = 0.93). No significant differences were observed regarding age and marital status between China and other regions.

Conclusions: This study highlights the prominent roles of age, marital status, and number of children in shaping fertility intentions among PLHIV. In China, the social and national context uniquely influences these intentions. Given the limited number of studies and variability in educational classifications across countries, further in-depth research is warranted.
