Studies from industrialized Western countries have reported an inverse association between socioeconomic status and overweight/obesity. In contrast, few studies from newly industrialized countries in Asia have examined this association. In this context, we examined the association between socioeconomic status and overweight/obesity by gender in Chinese adults in Singapore.
A population-based cross sectional study of 942 participants (57.3% women, 40-81 years) residing in the Tanjong Pagar district of Singapore was conducted. Education, income, and housing type were used as socioeconomic status indicators. Main outcome-of-interest was the presence of overweight/obesity (n=313), classified by body mass index as overweight (25- 29.9 kg/m(2)), or obese (> or =30 kg/m(2)).
The prevalence of overweight/obesity was 33% in men and 34% in women. In men, SES indicators were not associated with overweight/obesity. In women, SES indicators were found to be inversely associated with overweight/ obesity. Compared to women with secondary/higher education, the odds ratio (OR) (95% confidence interval [CI]) of overweight/obesity in women with primary/lower education was 2.5 (1.5-4.0). Compared to women earning > Singapore dollar (SGD) 1,000 per month, the OR (95% CI) of overweight/obesity among women earning < or =SGD 1,000 was 2.5 (1.4-4.5). Compared to women living in large size public apartments or private houses, the OR (95% CI) of overweight/obesity in women living in small/medium size public apartments was 1.8 (1.2-2.7).
Lower socioeconomic status, defined by education, income, and housing type was associated with overweight/obesity in Chinese Singaporean women.
来自西方工业化国家的研究报告称，社会经济地位与超重/肥胖之间存在负相关。相比之下，亚洲新兴工业化国家很少有研究探讨这种关联。在此背景下，我们研究了新加坡华裔成年人中社会经济地位与超重/肥胖之间按性别划分的关联。
对居住在新加坡丹戎巴葛区的942名参与者（57.3%为女性，年龄40 - 81岁）进行了一项基于人群的横断面研究。教育程度、收入和住房类型被用作社会经济地位指标。主要关注的结果是超重/肥胖的存在情况（n = 313），根据体重指数将超重定义为（25 - 29.9千克/平方米），肥胖定义为（≥30千克/平方米）。
男性超重/肥胖患病率为33%，女性为34%。在男性中，社会经济地位指标与超重/肥胖无关。在女性中，社会经济地位指标与超重/肥胖呈负相关。与接受中等/高等教育的女性相比，接受小学/低等教育的女性超重/肥胖的优势比（OR）（95%置信区间[CI]）为2.5（1.5 - 4.0）。与月收入超过1000新加坡元（SGD）的女性相比，月收入≤1000新加坡元的女性超重/肥胖的OR（95% CI）为2.5（1.4 - 4.5）。与居住在大型公共公寓或私人住宅的女性相比，居住在中小型公共公寓的女性超重/肥胖的OR（95% CI）为1.8（1.2 - 2.7）。
由教育程度、收入和住房类型定义的较低社会经济地位与新加坡华裔女性的超重/肥胖有关。
