Propensity score matching was performed to balance the age and gender between the Korean and UK populations, and 9903 out of 17,791 populations in the UK and 5541 out of 5759 populations in Korea were selected for the present study
Abbreviations: BMI, body mass index; T2DM, type2 diabetes mellitus; UK, United Kingdom
aDistribution of age and BMI was compared between the populations of UK and Korea using independent t tests
bDistribution of education level and presence of hypertension, T2DM, obesity, and underweight between the populations of UK and Korea were tested using the chi-squared test
