Diet and physical activity based interventions during pregnancy significantly reduce gestational weight gain compared to routine care, with a mean difference of -0.70 kg.
Engage in moderate physical activity and follow a balanced diet during pregnancy. This combination significantly reduces excessive weight gain and lowers the risk of caesarean section without harming the baby. These benefits apply to women of all body weights, not just those who are obese.
Less weight gain occurred in the intervention group than control group (mean difference −0.70 kg, 95% confidence interval −0.92 to −0.48 kg, I2=14.1%; 33 studies, 9320 women).
