Physical Activity and the Risk of Preeclampsia: A Systematic Review and Meta-Analysis

Abstract

BACKGROUND: Physical activity has been hypothesized to reduce the risk of preeclampsia, but epidemiologic studies have not shown consistent results. Therefore, we conducted a systematic review and dose-response meta-analysis of epidemiologic studies. METHODS: PubMed, Embase, and Ovid databases were searched for case-control and cohort studies of physical activity and preeclampsia up to 2 November 2012. We estimated summary relative risks (RRs) using a random effects model. RESULTS: Fifteen studies were included. The summary RR for high versus low prepregnancy physical activity was 0.65 (95% confidence interval [CI] = 0.47-0.89, I = 0%; n = 5). In the dose-response analysis, the summary RR was 0.72 (0.53-0.99; I = 0%; n = 3) per 1 hour per day and 0.78 (0.63-0.96; I = 0%; n = 2) per 20 metabolic equivalent task (MET)-hours per week. The summary RR for high versus low physical activity in early pregnancy was 0.79 (0.70-0.91; I = 0%; n = 11). In the dose-response analysis, the summary RR per 1 hour per day was 0.83 (0.72-0.95; I = 21%; n = 7) and 0.85 (0.68-1.07; I = 69%; n = 3) per 20 MET-hours per week. A nonlinear association was observed for physical activity before pregnancy and risk of preeclampsia (test for nonlinearity, P = 0.03), but not for physical activity in early pregnancy (test for nonlinearity, P = 0.37), with a flattening of the curve at higher levels of activity. Both walking and greater intensity of physical activity were inversely associated with preeclampsia. CONCLUSIONS: Our analysis suggests a reduced risk of preeclampsia with increasing levels of physical activity before pregnancy and during early pregnancy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
