This pilot study investigated whether established equations for estimating maternal percent body fat using anthropometry are accurate for Hispanic, overweight or obese pregnant women. Methods: The Siri technique of calculating percent body fat from direct measurements of body density and total body water was the gold-standard. Other pregnancy-specific equations were also examined. The study population included 15 normoglycemic, pregnant Hispanic women in their third trimester (33.2±1.9 gestational week) with a pre-pregnancy body mass index ≥25 to <40kg/m 2 , and with no history of chronic disease, or illicit drug, cigarette or alcohol use. Five skinfold sites, pre-pregnancy weight, current weight, and wrist circumference were measured. Body density was measured using air displacement plethysmography. Total body water was measured using 2 H2O. Results: Paired t-tests showed that the Paxton equation (intended for use at gestational week 37) overestimated percent body fat compared to the Siri method, p<0.001, whereas the Presley equation (intended for use at gestational week 30) produced statistically similar results to the gold-standard, p=0.842. Discussion: Using skinfold thickness measurements and the Presley equation to assess percent body fat may be useful and accessible for this population. © 2016 Californian Journal of Health Promotion.

在超重/肥胖的西班牙裔怀孕人群中评估体脂百分比的妊娠特异性方程的初步研究
背景和目的:超过一半的孕妇超重或肥胖,增加了代谢风险。这项初步研究调查了用人体测量法估计孕妇体脂百分比的既定方程对西班牙裔、超重或肥胖孕妇是否准确。方法:通过直接测量体密度和总水来计算体脂百分比的Siri技术是金标准。其他怀孕特有的方程也被检查。研究人群包括15名血糖正常的西班牙裔孕妇,孕晚期(33.2±1.9妊娠周),孕前体重指数≥25至<40kg/ m2,无慢性病史,无非法药物、吸烟或饮酒史。测量5个皮褶部位、孕前体重、当前体重和腕围。采用空气置换体积脉搏仪测量体密度。用2h2o测定全身水分。结果:配对t检验显示,与Siri方法相比,Paxton方程(拟用于妊娠第37周)高估了体脂百分比,p<0.001,而Presley方程(拟用于妊娠第30周)产生的统计结果与金标准相似,p=0.842。讨论:使用皮褶厚度测量和Presley方程来评估体脂百分比可能对这一人群有用且容易获得。©2016加州健康促进杂志。版权所有。
