To compare self-reported pre-pregnancy weight & delivery weight with documented pre-pregnancy & delivery weight and determine whether there are differences compared with the Institute of Medicine's (IOM) guidelines.
This is a retrospective analysis of 234 women. Inclusion criteria included documented height, self-reported pre-pregnancy weight, self-reported delivery weight, documented pre-pregnancy weight ± 12 weeks from last menstrual period, and documented delivery weight ± 2 weeks from delivery. We determined the difference between self-reported pre-pregnancy weight vs. documented pre-pregnancy weight and self-reported delivery weight vs. documented delivery weight. Using documented pre-pregnancy weight and documented delivery weight, we calculated gestational weight gain (GWG) relative to IOM criteria.
Self-reported pre-pregnancy weight was 2.94 kg less than documented pre-pregnancy weight (p < 0.0001). Self-reported BMI was 1.11 mg/kg(2) less than documented BMI (p < 0.0001). Self-reported GWG was 3.01 kg greater than documented GWG (p < 0.0001). Ninety-eight percent of normal weight correctly classified pregravid BMI in contrast to 86% of obese (p < 0.005) and 73% of overweight (p < 0.001).
Overweight and obese women underestimated self-reported pre-pregnancy weight & overestimated GWG, thereby mistakenly categorizing IOM guidelines.
比较自我报告的孕前体重和分娩体重与记录的孕前和分娩体重，并确定与医学研究所（IOM）指南相比是否存在差异。
这是一项对234名女性的回顾性分析。纳入标准包括记录的身高、自我报告的孕前体重、自我报告的分娩体重、距末次月经记录的孕前体重±12周，以及距分娩记录的分娩体重±2周。我们确定了自我报告的孕前体重与记录的孕前体重之间以及自我报告的分娩体重与记录的分娩体重之间的差异。使用记录的孕前体重和记录的分娩体重，我们计算了相对于IOM标准的孕期体重增加（GWG）。
自我报告的孕前体重比记录的孕前体重轻2.94千克（p<0.0001）。自我报告的BMI比记录的BMI低1.11mg/kg(2)（p<0.0001）。自我报告的GWG比记录的GWG高3.01千克（p<0.0001）。98%的正常体重女性正确分类孕前BMI，相比之下，肥胖女性为86%（p<0.005），超重女性为73%（p<0.001）。
超重和肥胖女性低估了自我报告的孕前体重并高估了GWG，从而错误地对IOM指南进行了分类。
