Abstract: Objective: To systematically describe and analyze the influencing factors of physical activity among pregnant women. Methods: Computer-assisted manual retrieval of researches on the factors influencing physical activity of pregnant women in 7 Chinese and English databases（PubMed, Web of Science, Embase, CNKI, Wanfang, Vip, China Biomedical Literature Database）. Literature screening, data extraction and quality evaluation were carried out according to the inclusion and exclusion criteria. The study results were summarized using content analysis guided by the social ecological model. Results: A total of 44 studies were included in this review. The factors affecting physical activity of pregnant women could be classified as individual, family and social factors. There are fewer studies focused on the family and social factors compared with individual factors. Conclusion: Consistent conclusions were reached on the effects of pre-pregnancy physical activity status, pre-pregnancy BMI, self-efficacy, family structure, and built environment on physical activity. Health care providers should develop multidimensional and precise physical activity promotion programs for pregnant women concerning intervenable influencing factors.
