| pubmed-article:6536223 | pubmed:abstractText | 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. | lld:pubmed |
