We examined relationships between sitting time and obesity or abdominal obesity according to sex and socioeconomic status in elderly people. We analyzed data from the Korean National Health and Nutrition Examination Survey 2013, and 1565 participants were included in the study. Multivariate logistic regression analysis was used to examine relationships between sitting time and obesity or abdominal obesity according to sex and socioeconomic status. Sitting time was positively correlated with body mass index in men and women and waist circumference in men. When considering socioeconomic factors, men who sat for 5 hours or longer and fell within the lowest income were more likely to have obesity and abdominal obesity relative to men who sat for 5 hours or shorter and earned higher incomes (odds ratio [95% confidence interval] = 1.80 [1.14-2.84] and 1.63 [1.02-2.61] respectively), and women who sat for 5 hours or longer and fell within the lowest educational level were more likely to have obesity relative to women who sat for 5 hours or less and were educated to a higher level (1.24 [1.01-1.85]). Strategies to reduce sedentary behavior would help to prevent obesity in older men who earn low incomes and women with lower levels of educational attainment.
我们根据老年人的性别和社会经济状况，研究了久坐时间与肥胖或腹部肥胖之间的关系。我们分析了2013年韩国国家健康与营养检查调查的数据，共有1565名参与者纳入本研究。采用多因素logistic回归分析，根据性别和社会经济状况研究久坐时间与肥胖或腹部肥胖之间的关系。久坐时间与男性和女性的体重指数以及男性的腰围呈正相关。考虑社会经济因素时，与久坐时间在5小时或更短且收入较高的男性相比，久坐时间在5小时或更长且收入最低的男性更易发生肥胖和腹部肥胖（比值比[95%置信区间]分别为1.80[1.14 - 2.84]和1.63[1.02 - 2.61]），与久坐时间在5小时或更短且受教育程度较高的女性相比，久坐时间在5小时或更长且受教育程度最低的女性更易发生肥胖（1.24[1.01 - 1.85]）。减少久坐行为的策略将有助于预防低收入老年男性和低教育程度女性肥胖。
