Optimal Weight Gain Recommendations For Non- Obese Japanese Pregnant Women

To determine optimal weight gain recommendations for reducing unfavorable pregnancy outcomes in non-obese women, by comparing four different cutoffs for weight gains. Out of 4774 cases in the hospital-based survey of the 2010National Growth Survey of Preschool Children, data on 3547 singleton term deliveries with maternal pre-pregnancy BMI<25.0 were selected. Two cutoffs for adequate weight gains, the Ministry of Health, Labour, and Welfare (MHLW), and the Japan Society for the Study of Hypertension in Pregnancy (JSSHP) weight gain guidelines were applied to identify “insufficient”, “adequate”, and “excess” weight gain groups. Logistic regression analyses were applied to estimate the risks for “insufficient” and “excess” weight gains to selected pregnancy outcomes.
