Determining the association between physical activity prior to conception and pregnancy rate: A systematic review and meta-analysis of prospective cohort studies

摘要

We investigated the association between physical activity (PA) before pregnancy and pregnancy rate according to intensity and amount of exercise. Eleven prospective cohort studies were included in this meta-analysis. Any amount of moderate-intensity PA was associated with a statistically higher rate of pregnancy compared to that in patients with no PA (p .05). In contrast, vigorous PA was associated with increased infertility (p > .05). Therefore, women who are preparing for pregnancy are recommended to perform regular, moderate-intensity PA.
