饮食相关健康结果的社会经济不平等是公认的，但消费的观察性研究并没有完全解释。我们提供了一个新的分析，以更准确地识别购买模式，根据数据带回家的食品和饮料购买25,674英国家庭在2010年。为了检查社会经济差异（按职业衡量），我们对从（a）43种食品或饮料类别和（B）主要营养素购买的能量比例进行了回归分析。结果显示，许多小的类别水平的社会经济差异。类别的汇总显示，较低的SES组通常从不太健康的食品和饮料中购买更大比例的能量，而较高的SES组则从更健康的食品和饮料中购买更大比例的能量（分别为65%和60%）。在营养水平上，社会经济差异不太明显，尽管较高的社会经济地位与购买较大比例的纤维，蛋白质和总糖以及较小比例的钠有关。所观察到的购买模式在社会经济地位群体之间的群体之间观察到的健康差异的解释和突出的目标，以减少健康不平等的干预措施。(c)2013作者由爱思唯尔有限公司出版。保留所有权利。
Socioeconomic inequalities in diet-related health outcomes are well-recognised, but are not fully explained by observational studies of consumption. We provide a novel analysis to identify purchasing patterns more precisely, based on data for take-home food and beverage purchases from 25,674 British households in 2010. To examine socioeconomic differences (measured by occupation), we conducted regression analyses on the proportion of energy purchased from (a) each of 43 food or beverage categories and (b) major nutrients. Results showed numerous small category-level socioeconomic differences. Aggregation of the categories showed lower SES groups generally purchased a greater proportion of energy from less healthy foods and beverages than those in higher SES groups (65% and 60%, respectively), while higher SES groups purchased a greater proportion of energy from healthier food and beverages (28% vs. 24%). At the nutrient-level, socioeconomic differences were less marked, although higher SES was associated with purchasing greater proportions of fibre, protein and total sugars, and smaller proportions of sodium. The observed pattern of purchasing across SES groups contributes to the explanation of observed health differences between groups and highlights targets for interventions to reduce health inequalities.
