This research project in urban marginal areas of the City of Hermosillo in Sonora, Mexico, analyzes certain socioeconomic factors taking into consideration the relationship between household income, expense and consumption of food. The study is based on information collected in a 24-hour recall survey carried out for all members of the family, frequency of consumption of foods, and a socioeconomic questionnaire. Expense and consumption of foods was divided into five different income groups and into three classes of foods: basic foods, fresh meat and high-protein foods. The results of the research study show a direct relationship between household income level and expense and consumption of the foods. The income-elasticity of the demand of basic foods was lower than that estimated for high-protein foods, and there was a marked tendency to increase consumption of high-protein foods as family income increased. More than 50% of the calories and proteins were obtained from the basic foods group, even though a large percentage of family food expense was destined for high-protein foods. The study concludes that more research is needed at a macroeconomic level to understand the basic underlying causes of the nutritional problems.
该研究项目位于墨西哥索诺拉州埃莫西约市的城市边缘地区，在考虑家庭收入、支出与食物消费之间关系的基础上，分析了某些社会经济因素。该研究基于对家庭所有成员进行的24小时回顾调查所收集的信息、食物消费频率以及一份社会经济调查问卷。食物支出和消费被划分为五个不同的收入群体以及三类食物：基本食物、鲜肉和高蛋白食物。研究结果表明家庭收入水平与食物支出和消费之间存在直接关系。基本食物需求的收入弹性低于高蛋白食物的估计值，并且随着家庭收入增加，高蛋白食物的消费有显著增加的趋势。尽管家庭食物支出的很大一部分用于高蛋白食物，但超过50%的卡路里和蛋白质来自基本食物组。该研究得出结论，需要在宏观经济层面进行更多研究，以了解营养问题的基本潜在原因。
