【Abstract】 Objectives To evaluate the optimal maternal weight gain patterns in twin pregnancy. Methods By describing the relationship between perinatal mortality,low birth weight and maternal weight gain in twins,find the optimal range of weight gain during pregnancy. Results Women with weight gain below 16 kg in pregnancy accounted for 62.9 %(892/1 417),below 10 kg for 21.2 %(300/1 417).The perinatal mortality was below 3 % as the maternal weight gain ranged between 16.0 and 24.0 kg.With the increasing of weight gain,the incidence of low-birth weight infants declined. Conclusion The results suggested,that maternal weight gain was associated with the perinatal outcome in twins.A range of 16.0～24.0 kg of maternal weight gain wowld be optimal in twin pregnancy.更多还原
