The objective of this population-based, large sample size study was to investigate the socioeconomic inequality of overweight and obesity among the elderly in Iran.
Baseline data of 3000 persons aged ≥60 years who participated in the Bushehr Elderly Health (BEH) program was analyzed. Overweight and obesity were defined as a body mass index (BMI) equal to or higher than 25 and 30, respectively. Socioeconomic status (SES) was measured by an asset index, constructed using principal component analysis, income, education level, and employment status. The Concentration Index and the Lorenz curve were used to illustrate the levels of inequality for overweight and obesity by gender.
The frequencies among men and women were, respectively, 840 (57.7%) and 1131 (73.2%), P < 0.001, for overweight, and 211 (14.7%) and 511 (33.7%), P < 0.001, for obesity. There were direct associations between asset index quintiles and both overweight and obesity among both genders (Ps for trend <0.01) except for obesity among men (P for trend = 0.118). The overall Concentration Indices for overweight and obesity were 0.031 (95%CI = 0.016-0.046, P < 0.001) and 0.041 (95%CI = 0.004-0.078, p = 0.028), respectively.
Findings support the direct relationship between SES and obesity among women as previously reported in developing countries.
这项基于人群的大样本研究旨在调查伊朗老年人超重和肥胖的社会经济不平等情况。
对参与布什尔老年人健康（BEH）项目的3000名60岁及以上人群的基线数据进行了分析。超重和肥胖分别定义为体重指数（BMI）等于或高于25和30。社会经济地位（SES）通过资产指数来衡量，该指数采用主成分分析、收入、教育水平和就业状况构建而成。集中指数和洛伦兹曲线用于按性别说明超重和肥胖的不平等程度。
超重方面，男性和女性的频率分别为840（57.7%）和1131（73.2%），P<0.001；肥胖方面，男性和女性的频率分别为211（14.7%）和511（33.7%），P<0.001。除男性肥胖外（趋势P=0.118），资产指数五分位数与男女超重和肥胖均存在直接关联（趋势P<0.01）。超重和肥胖的总体集中指数分别为0.031（95%CI=0.016-0.046，P<0.001）和0.041（95%CI=0.004-0.078，P=0.028）。
研究结果支持了发展中国家先前报道的女性社会经济地位与肥胖之间的直接关系。
