|
Background: The purpose of this study was to identify the differences in socioeconomic level of self-reported and measured obesity indicators (weight, height, body mass index, and obesity prevalence) and to compare the differences between factors.
Methods: Data of 2,290,893 weighted cases from the 2018 community health surveys in Busan were used to calculate self-reported and measured obesity and the prevalence of obesity. Logistic regression models were used to estimate the odds ratio of self-reported and measured obesity.
Results: The mean differences between self-reported and measured height, weight, and BMI were 0.53 cm, 0.66 kg, and 0.37 kg/m2 for men and 0.74 cm, 0.81 kg, and 0.55 kg/m2 for women, respectively. Self-reported and measured obesity prevalence rates were 35.36% and 40.79% in men and 20.55% and 27.16% in women, respectively. The difference between measured and self-reported values was high in the lower socioeconomic level group. Measured obesity, but not self-reported obesity, was significantly higher in the lower socioeconomic level group (level 3, odds ratio 1.26, 95% confidence interval 1.01-1.56).
Conclusions: These results indicate a requirement for obesity management policies for women with lower socioeconomic status.
