Accuracy of body weight perception is an individual's perception of their body weight in comparison with actual body weight and is associated with weight-related behaviors. Chinese Americans have increased risk for obesity but no studies have examined accuracy of body weight perception.
This study was a descriptive and cross-sectional study, which was conducted in a community health center in New York. Study subjects were all Chinese-American adults. Demographic information, accuracy of perception of body weight, anthropometric measures (weight, height, body mass index [BMI], waist circumference [WC], hip circumference [HC], weight to height ratio, weight to hip ratio), fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1C) and obesity-related diseases (hypertension, diabetes, heart disease, and stroke) were assessed.
A total of 162 Chinese Americans were recruited. 52 subjects (32%) did not perceive body weight correctly: 32 subjects had underestimation and 20 subjects had overestimation of body weight. Significant differences were found among subjects in the three groups of different accuracy of body weight perception in terms of gender (p=0.003), age (p=0.003), education years (p=0.047), WC (p<0.001), HC (p≤0.001), weight/height ratio (p=0.001), and BMI (p<0.001). Accuracy of perception of body weight significantly predicted WC (p<0.001), HC (p<0.001), weight to height ratio (p=0.001), BMI (p<0.001) and weight (<0.001) even after controlling for all demographic factors.
The study identified that around one-third of Chinese Americans did not perceive their body weight correctly. Intervention studies for obesity management in Chinese Americans should address gender difference, target on older subjects, and focus on educating the normal values and significances of WC, HC and HbA1C among Chinese Americans.
体重感知准确性是个体对自身体重与实际体重的认知，且与体重相关行为有关。华裔美国人肥胖风险增加，但尚无研究考察体重感知准确性。
本研究为描述性横断面研究，在纽约的一个社区健康中心开展。研究对象为所有成年华裔美国人。评估了人口统计学信息、体重感知准确性、人体测量指标（体重、身高、体重指数[BMI]、腰围[WC]、臀围[HC]、体重身高比、体重臀围比）、空腹血糖（FPG）、糖化血红蛋白（HbA1C）以及肥胖相关疾病（高血压、糖尿病、心脏病和中风）。
共招募了162名华裔美国人。52名受试者（32%）体重感知不正确：32名受试者低估体重，20名受试者高估体重。在体重感知准确性不同的三组受试者中，在性别（p = 0.003）、年龄（p = 0.003）、受教育年限（p = 0.047）、腰围（p < 0.001）、臀围（p≤0.001）、体重/身高比（p = 0.001）和BMI（p < 0.001）方面存在显著差异。即使在控制了所有人口统计学因素后，体重感知准确性仍能显著预测腰围（p < 0.001）、臀围（p < 0.001）、体重身高比（p = 0.001）、BMI（p < 0.001）和体重（p < 0.001）。
该研究发现约三分之一的华裔美国人对自身体重感知不正确。针对华裔美国人肥胖管理的干预研究应关注性别差异，以老年受试者为目标，并着重教育华裔美国人腰围、臀围和糖化血红蛋白的正常值及意义。
