The objective of this study is to evaluate whether the relation between area-based socioeconomic environment and childhood obesity can be explained by household socioeconomic position, obesity-related risk behaviours and area facilities.
Two indicators of socioeconomic environment based on wealth and deprivation were estimated in a sample of 4529 Spanish children and adolescents in 2006. Multilevel logit models were used to calculate the relation between each indicator and obesity.
After adjusting for socioeconomic position and risk behaviours, no relation was observed between wealth and overweight; however, obesity prevalence was 1.45 times higher in subjects living in areas with lower wealth than in those living in areas with higher wealth. After adjusting for these variables, the prevalence of overweight and obesity in subjects living in deprived areas was, respectively, 1.26 and 1.63 higher than in those living in non-deprived areas. There was a graded association between number of sports facilities and prevalence of physical inactivity, but no relation was found between the price of fruits and vegetables and frequency of consumption.
The relation of socioeconomic environment with childhood obesity could not be explained by household socioeconomic position or obesity-related risk behaviours. Availability of sport facilities may mediate this relation.
本研究旨在评估基于区域的社会经济环境与儿童肥胖之间的关系是否可以通过家庭社会经济地位、肥胖相关风险行为和区域设施来解释。
在 2006 年，对西班牙 4529 名儿童和青少年样本中基于财富和贫困的两个社会经济环境指标进行了估计。使用多层逻辑回归模型计算了每个指标与肥胖之间的关系。
在调整社会经济地位和风险行为后，与超重相比，财富与肥胖之间没有关系；然而，生活在财富较低地区的儿童肥胖的患病率比生活在财富较高地区的儿童肥胖的患病率高 1.45 倍。在调整这些变量后，生活在贫困地区的儿童超重和肥胖的患病率分别比生活在非贫困地区的儿童高 1.26 倍和 1.63 倍。体育设施的数量与身体活动不足的流行率呈梯度关联，但水果和蔬菜的价格与消费频率之间没有关系。
社会经济环境与儿童肥胖之间的关系不能通过家庭社会经济地位或肥胖相关风险行为来解释。运动设施的可用性可能会调节这种关系。
