The purpose of this study was to estimate and compare total gestational weight gain (GWG) and the trimester-specific mean rate of GWG based on pre-pregnancy body mass index (BMI) as recommended by the Institute of Medicine (IOM).
The medical records of 470 participants who had received antenatal care at medical teaching hospitals in northern Taiwan and who delivered after 37 weeks of pregnancy were analyzed.
The mean total GWG was 13.84 (SD = 4.33) kg, and nearly 60% of women had not complied with the current IOM recommendations for total GWG. The best-fit model for the mean GWG rate revealed that all groups had a GWG rate of zero in the 1st trimester and had an equivalent mean GWG rate in the 3rd trimester. Women tended to have excessive weekly GWG in the 2nd and 3rd trimesters, and women with a higher pre-pregnancy BMI were more likely to have excessive weekly GWG in the 2nd and 3rd trimesters. Moreover, the plurality of normal-weight (30.4%), overweight (75.8%) and obese (62.5%) women experienced excessive weekly weight gain during the 2nd and 3rd trimesters. Few women met the recommended 2009 IOM weekly weight-gain guidelines in the 2nd trimester, but more met them in the 3rd trimester.
These findings indicate that most pregnant Taiwanese women currently exceed the total and weekly GWG recommendations of the IOM. More specifically, weekly GWG in excess of the IOM recommendations is common among normal-weight, overweight and obese women.
本研究旨在根据美国医学研究所（IOM）的建议，估算并比较基于孕前体重指数（BMI）的孕期总体重增加量（GWG）以及孕期各阶段的平均GWG率。
分析了470名在台湾北部医学教学医院接受产前护理且妊娠37周后分娩的参与者的病历。
平均总体重增加量为13.84（标准差 = 4.33）千克，近60%的女性未遵循IOM当前关于总体重增加量的建议。平均GWG率的最佳拟合模型显示，所有组在孕早期的GWG率为零，在孕晚期的平均GWG率相等。女性在孕中期和孕晚期往往每周体重增加过多，孕前BMI较高的女性在孕中期和孕晚期更有可能每周体重增加过多。此外，多数正常体重（30.4%）、超重（75.8%）和肥胖（62.5%）女性在孕中期和孕晚期体重每周增加过多。在孕中期，很少有女性达到2009年IOM推荐的每周体重增加指南，但在孕晚期达到的女性更多。
这些发现表明，目前大多数台湾孕妇的总体重增加量和每周体重增加量超过了IOM的建议。更具体地说，正常体重、超重和肥胖女性中，每周体重增加量超过IOM建议的情况很常见。
