Obesity is associated with poor asthma outcomes; weight loss improves such outcomes. Inaccurate recognition of obesity may impede weight control.
We examined perception of weight by early adolescents with uncontrolled asthma and their caregivers, and tested the relationship between medical visit frequency and accuracy of perceived weight status.
A total of 373 adolescents and their caregivers reported the adolescent’s height/weight and weight perception; caregivers reported healthcare utilization. We measured height/weight. Logistic regression modeled accuracy of weight perception.
A total of 43.7 % of the overweight/obese adolescents and caregivers accurately perceived weight status. BMI percentile [odds ratio (OR) = 1.19, confidence interval (CI) = 1.10–1.28] and total medical visits (OR = 1.18, CI = 1.05–1.33) were associated with higher accuracy in caregivers. Total medical visits (OR = 0.84, CI = 0.74–0.96) was associated with lower accuracy in adolescents.
Accurate perception of weight status was poor for overweight adolescents with uncontrolled asthma and their caregivers. Frequent medical visits were associated with improved caregivers’ but not adolescents’ perceptions.

    ABSTRACT: 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.
