Abstract
Objective
To evaluate the effectiveness of restricting weight gain during pregnancy to reduce
perinatal complications.
Study design
The study was conducted in the Tokyo metropolitan area, and reviewed 3071 mothers
and their infants born from singleton pregnancies retrospectively. To examine the
influence of increased maternal weight gain on perinatal complications, we performed
five-category stratification for weight gain: less than 8.0, 8.0–10.0, 10.1–12.0,
12.1–14.0 and over 14.0 kg.
Results
Total weight gains less than 8.0 kg significantly increased the risk of low birth weight (LBW) and small for gestational
age (SGA) infants (OR = 2.19, 95% CI; 1.36–3.52, OR = 1.76, 95% CI; 1.23–2.51) and total weight gain over 14.0 kg significantly increased the risk of large for gestational age (LGA) infants and
pregnancy induced hypertension (PIH) (OR = 3.06, 95% CI; 1.88–4.98, OR = 2.87, 95% CI; 1.86–4.42, respectively), compared with women with weight gain of 10.1–12.0 kg. The groups with weight gains of 8.0–10.0 kg and 12.1–14.0 kg did not show adverse perinatal outcomes, including gestational diabetes (GDM),
cesarean delivery, postpartum hemorrhage and laceration, significantly different from
the 10.1 to 12.0 kg gain group.
Conclusion
Strict restriction of weight gain during pregnancy is not effective in reducing perinatal
complications.
