目的：儿童肥胖症已成为全球优先关注的健康问题。社会经济地位是其主要决定因素之一。本研究旨在评估社会经济不平等的肥胖儿童和青少年在国家和省一级在Iran.Methods：这项多中心的横断面研究进行了2011-2012年，作为一个国家的学校为基础的监测计划的一部分，在40,000名学生，年龄在6-18岁，从城市和农村地区的30个省的伊朗。使用主成分分析，参与者的社会经济地位被归类为五分之一。超重的社会经济地位不平等是通过计算超重的流行率来估计的（即，超重、全身性肥胖和腹部肥胖）、集中指数和不平等斜率指数。这种不平等的决定因素是由瓦哈卡Blinder分解。结果：总体而言，36,529名学生完成了研究（响应率：91.32%），其中50.79%是男孩和74.23%是城市居民。平均（标准差）年龄为12.14（3.36）岁。超重、全身性肥胖和腹型肥胖的患病率分别为11.51%、8.35%和17.87%。超重、肥胖和腹型肥胖的SII分别为-0.1、-0.1和-0.15。超重、全身性肥胖和腹型肥胖的集中指数为正，这表明不平等有利于低社会经济地位群体。居住区，肥胖家族史，年龄是最有影响的因素肥胖患病率之间观察到的最高和最低的社会经济地位groups.Conclusion的不平等：这项研究提供了相当多的信息，在国家和省一级的高社会经济地位的家庭超重的高患病率。这些研究结果可用于国际比较和医疗保健政策，通过考虑省一级的差异来改善其规划。(C)2017年巴西儿科学会。出版社：Elsevier Editora Ltda
Objective: Childhood obesity has become a priority health concern worldwide. Socioeconomic status is one of its main determinants. This study aimed to assess the socioeconomic inequality of obesity in children and adolescents at national and provincial levels in Iran.Methods: This multicenter cross-sectional study was conducted in 2011-2012, as part of a national school-based surveillance program performed in 40,000 students, aged 6-18-years, from urban and rural areas of 30 provinces of Iran. Using principle component analysis, the socioeconomic status of participants was categorized to quintiles. Socioeconomic status inequality in excess weight was estimated by calculating the prevalence of excess weight (i.e., overweight, generalized obesity, and abdominal obesity) across the socioeconomic status quintiles, the concentration index, and slope index of inequality. The determinants of this inequality were determined by the Oaxaca Blinder decomposition.Results: Overall, 36,529 students completed the study (response rate: 91.32%); 50.79% of whom were boys and 74.23% were urban inhabitants. The mean (standard deviation) age was 12.14 (3.36) years. The prevalence of overweight, generalized obesity, and abdominal obesity was 11.51%, 8.35%, and 17.87%, respectively. The SII for overweight, obesity and abdominal obesity was -0.1, -0.1 and -0.15, respectively. Concentration index for overweight, generalized obesity, and abdominal obesity was positive, which indicate inequality in favor of low socioeconomic status groups. Area of residence, family history of obesity, and age were the most contributing factors to the inequality of obesity prevalence observed between the highest and lowest socioeconomic status groups.Conclusion: This study provides considerable information on the high prevalence of excess weight in families with higher socioeconomic status at national and provincial levels. These findings can be used for international comparisons and for healthcare policies, improving their programming by considering differences at provincial levels.
