Abstract


Objectives: This work investigates differences in height, weight, BMI, and obesity rate between 2018 Community Health Survey (CHS) and Korea National Health and Nutrition Examination Survey (KNHANES).

Methods: Two national surveys KNHANES and CHS were investigated for body measurements in terms of actual measurements. Considering sampling designs, complex sample analyses were performed using SAS 9.4 for descriptive statistics and t-tests.

Results: Adult obesity rate from KNHANES is 41.9% for males and 28.2% for females, which is not significantly different from 41.3% for males and 27.2% for females from CHS actual measurements. BMI from KNHANES is 24.6 kg/m2 for males and 23.2 kg/m2 for females, which is also not significantly different from 24.6 kg/m2 for males and 23.2 kg/m2 for females from CHS actual measurements. However, heights and weights were significantly smaller in most of gender and age groups in CHS than KNHANES.

Conclusions: Actual measurements of obsesity rates and BMI from CHS are not much different from the ones from KNHANES while heights and weights were significantly different between the two surveys. This requires attention when using the data.
