“…Five cohort studies 34,39,44,49,51 and two randomized trials 64,65 were included in the analysis of walking during pregnancy and preterm birth, and included 1065 cases and 26 903 participants. The summary RR for high versus low walking was 1.09 (95% CI: 0.68-1.75, I 2 = 72.3%, P heterogeneity < 0.0001; Figure 4E).…”

Background Physical activity has been inconsistently associated with risk of preterm birth, and the strength of the association and the shape of the dose–response relationship needs clarification. Objectives To conduct a systematic review and dose–response meta‐analysis to clarify the association between physical activity and risk of preterm birth. Search strategy PubMed, Embase and Ovid databases were searched for relevant studies up to 9 February 2017. Selection criteria Studies with a prospective cohort, case‐cohort, nested case‐control or randomized study design were included. Data collection and analysis Data were extracted by one reviewer and checked for accuracy by a second reviewer. Summary relative risks (RRs) were estimated using a random effects model. Main results Forty‐one studies (43 publications) including 20 randomized trials and 21 cohort studies were included. The summary RR for high versus low activity was 0.87 [95% confidence interval (CI): 0.70–1.06, I2 = 17%, n = 5] for physical activity before pregnancy, and it was 0.86 (95% CI: 0.78–0.95, I2 = 0%, n = 30) for early pregnancy physical activity. The summary RR for a 3 hours per week increment in leisure‐time activity was 0.90 (95% CI: 0.85–0.95, I2 = 0%, n = 5). There was evidence of a nonlinear association between physical activity and preterm birth, Pnonlinearity < 0.0001, with the lowest risk observed at 2–4 hours per week of activity. Conclusion This meta‐analysis suggests that higher leisure‐time activity is associated with reduced risk of preterm birth. Further randomized controlled trials with sufficient frequency and duration of activity to reduce the risk and with larger sample sizes are needed to conclusively demonstrate an association. Tweetable abstract Physically active compared with inactive women have an 10–14% reduction in the risk of preterm birth.

“…A recent meta-analysis found that women with depression were more likely to have preterm birth (RR= 1.24, 95%CI: 1.04-1.47)(Grote et al, 2010). In contrast, a recent study reported that African-American women who walked for a purpose for more than 30 minutes per day during pregnancy had lower risk of preterm birth (Sealy-Jefferson et al, 2014). To our knowledge, this is the first study to examine the mediating effect of walking for a purpose on the effects of symptoms of depression on gestational age at birth.…”

“…In a prior study of low income African-American women in Baltimore, the researchers found an increased odds of preterm birth for women who walked for a purpose four days or more per week (Misra, Strobino, Stashinko, Nagey, & Nanda, 1998). In contrast, another study in the same city (different institution) reported that African-American women who walked for a purpose for more than 30 minutes per day during pregnancy had lower risk of preterm birth (Sealy-Jefferson, Hegner, & Misra, 2014). Misra and associates (1998) defined walking for a purpose as the average number of days per week in the first and second trimesters combined that a woman spent walking for a purpose and did not collect duration of walking for a purpose (i.e., minutes per day).…”

“…Misra and associates (1998) defined walking for a purpose as the average number of days per week in the first and second trimesters combined that a woman spent walking for a purpose and did not collect duration of walking for a purpose (i.e., minutes per day). In contrast, Sealy-Jefferson and colleagues (2014) asked open-ended questions about the duration of walking for a purpose (minutes per day) which may have decreased recall bias. Duration of walking for a purpose (minutes per day) may be a better measure to use when examining the association between walking for a purpose and gestational age at birth.…”

Background Symptoms of depression have been related to lower gestational age and preterm birth (less than 37 completed weeks gestation). Leisure time physical activity may have protective effects on preterm birth; however, less has been published with regard to other domains of physical activity such as walking for a purpose (e.g., for transportation) or the pathways by which symptoms of depression impact gestational age at birth. Methods This was a secondary analysis of available data of African-American women. Women were interviewed within three days after birth. We proposed a model in which walking for a purpose during pregnancy mediated the effects of symptoms of depression (measured by the 20-item Center for Epidemiologic Studies-Depression, CES-D, scale) on gestational age at birth in a sample of 1382 African-American women. Results Using structural equation modeling (SEM), we found that the direct effect of CES-D scores ≥ 23, which have been correlated with major depression diagnosis, on gestational age at birth was −4.23 (p < .001). These results indicate that symptoms of depression were associated with a decrease in gestational age at birth of 4.23 days. Walking for a purpose mediated the effect of CES-D scores ≥ 23 on gestational age at birth. Conclusion Compared with African-American women without symptoms of depression, African-American women who had symptoms of depression walked less for a purpose during their pregnancy and delivered infants with lower gestational age at birth. If not medically contraindicated, clinicians should incorporate walking as part of prenatal care recommendations and reassure women about safety of walking during pregnancy.
