Abstract

OBJECTIVE

To compare the gestational weight gain of healthy Thai singleton pregnant women with the U.S. Institute of Medicine (IOM) recommendation.

MATERIAL AND METHOD

One thousand eight hundredforty nine medical records ofuncomplicated singleton pregnant women who delivered at Siriraj Hospital between January 2007 and November 2010 were reviewed. All subjects were divided into four subgroups according to their pre-pregnancy body mass index (BMI): underweight (<18.5 kg/m2), normal weight (18.5-24.9 kg/m2), overweight (25.0-29.9 kg/m2), and obese group (> or =30 kg/m2). Their baseline characteristics and gestational weight gain were collected and reported One-way analysis of variance test was used to compare continuous data and Chi-squared test was used to compare discrete data among groups.

RESULTS

Mean gestational weight gain of normal weight, underweight, overweight, and obese women were 14.2+/-4.7 kg, 14.1+/-4.3 kg, 12.4+/-4.7 kg, and 10.8+/-4.3 kg and gestational weight gain between 25th to 75th percentile were 11.0 to 17.0 kg, 11.0 to 16.5 kg, 10.0 to 15.0 kg, and 8.0 to 13.0 kg for pregnant women with pre-pregnancy normal weight, underweight, overweight and obesity respectively. Significant difference of maternal age, gestational weight gain, neonatal birth weight, and parity were found among groups (p<0.05). About one-thirdofpre-pregnancy normal BMI (39.2%), overweight (36.6%), and obese (31.9%) as well as nearly halfofpre-pregnancy underweight group (47.6%) gained the appropriate weight based on the US.IOM recommendation. About one-third of pre-pregnancy underweight (37.9%) and normal BMI group (30.6%) gained less than the recommendation. Majority of pre-pregnancy overweight (52.3%) and obese (63.8%) group gained more weight than the recommendation.

CONCLUSION

Although pregnancy outcomes were normal, less than half of Thai pregnant women gained the appropriate weight based on the U.S. IOM recommendation.

摘要

目的

比较泰国健康单胎孕妇的孕期体重增加情况与美国医学研究所（IOM）的建议。

材料与方法

回顾了2007年1月至2010年11月在诗里拉吉医院分娩的1849例无并发症单胎孕妇的病历。所有受试者根据孕前体重指数（BMI）分为四个亚组：体重过轻（<18.5kg/m²）、正常体重（18.5 - 24.9kg/m²）、超重（25.0 - 29.9kg/m²）和肥胖组（≥30kg/m²）。收集并报告她们的基线特征和孕期体重增加情况。采用单因素方差分析检验比较连续数据，采用卡方检验比较组间离散数据。

结果

正常体重、体重过轻、超重和肥胖女性的平均孕期体重增加分别为14.2±4.7kg、14.1±4.3kg、12.4±4.7kg和10.8±4.3kg，孕前体重正常、体重过轻、超重和肥胖孕妇在第25至75百分位数之间的孕期体重增加分别为11.0至17.0kg、11.0至16.5kg、10.0至15.0kg和8.0至13.0kg。各组间产妇年龄、孕期体重增加、新生儿出生体重和平产次数存在显著差异（p<0.05）。根据美国IOM建议，约三分之一的孕前正常BMI（39.2%）、超重（36.6%）和肥胖（31.9%）孕妇以及近一半的孕前体重过轻组（47.6%）孕妇体重增加适宜。约三分之一的孕前体重过轻（37.9%）和正常BMI组（30.6%）孕妇体重增加低于建议值。大多数孕前超重（52.3%）和肥胖（63.8%）组孕妇体重增加超过建议值。
