We examined the relationship between income and education level with BMI and waist circumference to provide further understanding of the relationship between socioeconomic status and obesity and to identify the presence of sex differences.
A total of 7962 people >or=20 years of age (3597 men; 4365 women) who participated in the 1998 Korean National Health and Nutrition Examination Survey provided data including height, weight, waist circumference, education, and income level. We examined adjusted BMI and waist circumference according to level of income and education and the association between income and education with obesity and abdominal obesity by multiple logistic regression analysis.
In men, significant dose-response relationships were noted between income and obesity (trend, p < 0.05) and abdominal obesity (trend, p < 0.05). Compared with the lowest income group, the adjusted odds ratios (ORs) (95% confidence interval) of the highest income group for obesity and abdominal obesity were 1.65 (1.18 to 2.32) and 1.37 (0.94 to 1.98), respectively. However, income was not associated with obesity or abdominal obesity in the fully adjusted models in women. With regard to education, women showed significantly decreased ORs, with inverse trends for obesity and abdominal obesity across all education levels. Compared with the lowest education group, the adjusted ORs (95% confidence interval) for obesity and abdominal obesity were 0.66 (0.57 to 0.76) and 0.40 (0.35 to 0.45), respectively, among women with 7 to 12 years of schooling and 0.27 (0.21 to 0.34) and 0.15 (0.12 to 0.18), respectively, among women with 13 or more years of schooling.
Socioeconomic difference has a considerable impact on the prevalence of obesity among the Korean population, and the patterns differ substantially across sex.
我们研究了收入和教育水平与体重指数（BMI）及腰围之间的关系，以进一步了解社会经济地位与肥胖之间的关系，并确定性别差异的存在情况。
共有7962名年龄≥20岁的人（3597名男性；4365名女性）参与了1998年韩国全国健康与营养检查调查，提供了包括身高、体重、腰围、教育程度和收入水平的数据。我们根据收入和教育水平检查了调整后的BMI和腰围，并通过多元逻辑回归分析研究了收入和教育与肥胖及腹型肥胖之间的关联。
在男性中，收入与肥胖（趋势，p<0.05）和腹型肥胖（趋势，p<0.05）之间存在显著的剂量反应关系。与最低收入组相比，最高收入组肥胖和腹型肥胖的调整后比值比（OR）（95%置信区间）分别为1.65（1.18至2.32）和1.37（0.94至1.98）。然而，在女性的完全调整模型中，收入与肥胖或腹型肥胖无关。关于教育程度，女性在所有教育水平上肥胖和腹型肥胖的OR均显著降低，呈相反趋势。与最低教育组相比，接受7至12年教育的女性中肥胖和腹型肥胖的调整后OR（95%置信区间）分别为0.66（0.57至0.76）和0.40（0.35至0.45），接受13年或以上教育的女性中分别为0.27（0.21至0.34）和0.15（0.12至0.18）。
社会经济差异对韩国人群肥胖患病率有相当大的影响，且性别间模式差异很大。
