将共生-第21孕期体重增加标准与产妇产后体重超标的风险联系起来，这与连续怀孕之间的体重变化大致相同。加拿大不列颠哥伦比亚省对58,534名连续怀孕的妇女(2000-2015)进行了一项以人口为基础的回顾性队列研究。使用共生-21标准将妊娠指数中的妊娠增重(Kg)转换为胎龄标准化的z评分。过度解释体重增加被定义为下一次怀孕时体重增加5公斤、10公斤或肥胖(≥30公斤/平方米)。通过Logistic回归分析发现，体重增加、z分数和过度解释体重变化之间存在关联。对于过度解释体重增加的所有定义，体重增加z分数为0(50%)以下的风险保持较低和稳定，但随着z分数增加到零以上，风险急剧上升。与−1至0 SD(第16至50百分位数)的女性相比， >； 0至 +1 SD(第51至84百分位数)的女性在两次怀孕之间保持超重的可能性高出55%至84%。女性体重增加+1 SD的风险是女性的三到六倍。共生-第21百分位数的较大范围与过度口译体重增加的风险增加有关。该标准可能会使体重超标风险增加的女性体重增加正常化。
To link the INTERGROWTH‐21st gestational weight gain standard with the risks of excess maternal postpartum weight retention, approximated by women's weight change between successive pregnancies. A population‐based retrospective cohort study of 58,534 women delivering successive pregnancies in British Columbia, Canada (2000‐2015) was conducted. Pregnancy weight gain (kg) in the index pregnancy was converted into a gestational age‐standardized z‐score using the INTERGROWTH‐21st standard. Excess interpregnancy weight gain was defined as weight increases of 5 kg, 10 kg, or obesity (≥30 kg/m2) at the next pregnancy. Weight gain z‐scores and excess interpregnancy weight change were associated using logistic regression. For all definitions of excess interpregnancy weight gain, risks remained low and stable below a weight gain z‐score of 0 (50th percentile) but rose sharply with increasing z‐scores above zero. Compared with women gaining −1 to 0 SD (16th to 50th percentiles), women gaining > 0 to +1 SD (51st to 84th percentiles) were 55% to 84% more likely to retain excess weight between pregnancies. Risks were three‐ to sixfold higher in women gaining >+1 SD. A large range of the INTERGROWTH‐21st percentiles were associated with increased risks of excess interpregnancy weight gain. The standard may normalize high weight gains of women at increased risk of excess weight retention.
