This study aimed to determine an effective survey method for the accurate calculation of obesity prevalence by comparing the self-reported and measured height, weight, and body mass index (BMI) using the 2018 Korea Community Healthy Survey (CHS) data.
Raw data from the 2018 CHS were used to analyze the differences, correlation, and agreement between self-reported and measured height, weight, and BMI.
The self-reported height was over-reported than the measured height (0.59 cm greater for men and 0.71 cm greater for women), while the self-reported weight was under-reported than the measured weight (0.55 kg less for men and 0.67 kg less for women). Subsequently, the self-reported BMI was under-estimated (0.35 kg/m2 lower for men and 0.49 kg/m2 lower for women) compared with the measured BMI. The kappa statistic and agreement between measured and self-reported values per BMI category (underweight, normal, overweight, and obesity) were 0.82 and 79.6%, respectively.
The prevalence of obesity should be calculated using the measured values provided in the CHS in order to promote local health projects based on accurate evidence.
本研究旨在通过比较 2018 年韩国社区健康调查（CHS）数据中自我报告的和测量的身高、体重和体重指数（BMI），确定一种准确计算肥胖患病率的有效调查方法。
使用 2018 年 CHS 的原始数据来分析自我报告的和测量的身高、体重和 BMI 之间的差异、相关性和一致性。
自我报告的身高高于测量的身高（男性高 0.59 厘米，女性高 0.71 厘米），而自我报告的体重低于测量的体重（男性低 0.55 公斤，女性低 0.67 公斤）。随后，与测量的 BMI 相比，自我报告的 BMI 被低估（男性低 0.35kg/m2，女性低 0.49kg/m2）。按 BMI 类别（体重不足、正常、超重和肥胖）划分，测量值和自我报告值之间的kappa 统计量和一致性分别为 0.82 和 79.6%。
为了基于准确的证据推动当地健康项目，应使用 CHS 中提供的测量值来计算肥胖症的患病率。
