Previous studies have shown that overweight (including obesity) has increased significantly in Korea in recent decades. However, it remains unclear whether this change has been uniform among all Koreans and to what extent socioeconomic and behavioral factors have contributed to this increase.
Changes in overweight were estimated using data from the 1998, 2001, 2005, 2007-2009, and 2010-2012 Korea National Health and Nutrition Examination Survey (n=55 761).
Overweight increased significantly among men but not among women between 1998 and 2012. Changes in socioeconomic and behavioral factors over the time period were not associated with overall trends for both men and women. However, we found significant differences in the prevalence of overweight relative to key risk factors. For men, overweight increased at a significantly greater rate among the non-exercising (predicted probability [PP] from 0.23 to 0.32] and high-calorie (PP from 0.18 to 0.37) groups compared to their active and lower-calorie counterparts, respectively. For women, overweight increased only among the non-exercising (PP from 0.27 to 0.28) and low-income (PP from 0.31 to 0.36) groups during this period.
These findings suggest that programs aimed at reducing overweight should target Korean men and women in specific socioeconomic and behavioral risk groups differentially.
以往研究表明，近几十年来韩国超重（包括肥胖）情况显著增加。然而，目前尚不清楚这种变化在所有韩国人中是否一致，以及社会经济和行为因素在多大程度上导致了这种增加。
利用1998年、2001年、2005年、2007 - 2009年以及2010 - 2012年韩国国民健康与营养检查调查（n = 55761）的数据估算超重情况的变化。
1998年至2012年间，男性超重情况显著增加，而女性则未增加。在此期间社会经济和行为因素的变化与男性和女性的总体趋势均无关联。然而，我们发现超重患病率相对于关键风险因素存在显著差异。对于男性，与积极锻炼和低热量摄入组相比，不锻炼组（预测概率[PP]从0.23增至0.32）和高热量摄入组（PP从0.18增至0.37）的超重增加速率显著更高。在此期间，对于女性，超重仅在不锻炼组（PP从0.27增至0.28）和低收入组（PP从0.31增至0.36）中有所增加。
这些发现表明，旨在减少超重的项目应针对处于特定社会经济和行为风险组的韩国男性和女性进行差异化干预。
