Recent Epidemiological Changes in Korean Obesity

Abstract

In Korea, the prevalence of obesity as defined by body mass index(BMI) ≥25 kg/m² has been steady in the recent years; however, the prevalence of severe (BMI ≥30 kg/m²) and extreme obesity (BMI ≥35 kg/m²) has rapidly increased during the past decade. The change in the prevalence of abdominal obesity showed a similar trend to the prevalence of obesity. Based on the Korean data, the list of obesity-related diseases in Korea resembles those for the Western countries. The association between BMI and all-cause mortality in Koreans displayed a ‘U’ or inverted ‘J’ curve pattern. However, these curves have changed, and the BMI nadir of these curves exhibits a change to a higher BMI point during the past decades. Recent change in the obesity epidemic in Korea seems to resemble the previous changes in the obesity epidemics seen in the Western populations.
