Abstract: Objective To explore the impact of pregnant women's physical activity during pregnancy on newborns' weight on plateau region. Methods From June 2013 to June 2016, among the pregnant women who took prenatal care in Xining Second People's Hospital or Maternal and Child Health Care and Family Planning Service Center of Datong County, unipara without pregnancy complications were enrolled in this study. Their step counts were monitored for four days in the second and late trimester of pregnancy, respectively. And the pregnant women were divided into sedentary, low active, active and high active groups according to the mean daily steps. The general conditions and indexes related to newborn birth weight of the four groups were compared. The statistical analysis was performed by ANOVA, χ2 test and Fisher exact test. Results 418 pregnant women were enrolled in this study and were followed up after delivery. There was no statistical difference in the age, gestational age, BMI before pregnancy and average daily dietary energy intake among four groups (P﹥0.05). The weight before delivery of high active group was lower than that of sedentary and low active group ［(65.1±8.1) vs (69.6±8.3) and (68.4±7.9) kg, P﹤0.01］; the weight before delivery of active groups was lower than that of sedentary group ［(66.5±8.2) vs (69.6±8.3) kg,P﹤0.01］. The newborn's birth weight of high active group was lower than that of sedentary and low active group［(3 358±402) vs (3 602±448) and (3 527±436) g, P﹤0.01］; the newborn's birth weight of active group was lower than that of sedentary group ［(3 418±438) vs (3 602±448) g, P﹤0.01］. Conclusions The newborn's birth weight is related to the degree of maternal physical activity. Appropriate physical activity is helpful to control the newborn's birth weight and to prevent macrosomia.
