To investigate the potential associations of maternal prepregnancy body mass index (mppBMI) and gestational weight gain (GWG) with physical fitness in children.
A random sample of 5125 children and their mothers was evaluated. The mothers provided data contained in their medical booklets and pregnancy ultrasound records. The data from 5 physical fitness tests (eg, 20-m shuttle run, 30-m sprint, vertical jump, standing long jump, and small ball throw) were used to assess children's cardiorespiratory fitness, speed, explosive power, and lower and upper body strength, respectively.
MppBMI was inversely associated with cardiorespiratory fitness (b = -0.02), lower body strength (b = -1.01), upper body strength (b = -0.07), and speed (b = 0.04). Also, GWG was unfavorably associated with cardiorespiratory fitness (b = -0.02), lower body strength (b = -1.12), upper body strength (b = -0.03), and speed (b = 0.03), after adjusting for sex, birth weight, and children's BMI (all P values < .05). Children of mothers with an mppBMI ≥ 25 kg/m2 and excess GWG had almost 30% and 20% increased odds for low performances in physical fitness tests than those of mothers with an mppBMI < 25 kg/m2 and adequate GWG, respectively.
Antenatal factors such as increased mppBMI and excess GWG could play an unfavorable role in the future health of the offspring.
探讨母亲孕前体重指数（mppBMI）和孕期体重增加（GWG）与儿童体能的潜在关联。
对 5125 名儿童及其母亲进行了随机抽样。母亲提供了她们医疗手册和妊娠超声记录中的数据。使用 5 项体能测试（如 20 米穿梭跑、30 米冲刺、垂直跳跃、立定跳远和小皮球投掷）的数据，分别评估儿童的心肺功能、速度、爆发力、上下肢力量。
mppBMI 与心肺功能（b = -0.02）、下肢力量（b = -1.01）、上肢力量（b = -0.07）和速度（b = 0.04）呈负相关。此外，调整性别、出生体重和儿童 BMI 后，GWG 与心肺功能（b = -0.02）、下肢力量（b = -1.12）、上肢力量（b = -0.03）和速度（b = 0.03）呈负相关（均 P 值<.05）。mppBMI≥25kg/m2 和 GWG 过多的母亲所生孩子在体能测试中的表现不佳的几率比 mppBMI<25kg/m2 和 GWG 适当的母亲所生孩子分别高出近 30%和 20%。
产前因素如 mppBMI 增加和 GWG 过多可能对后代的未来健康产生不利影响。
