The objective of this study was to explore demographic and economic characteristics associated with household food security of 2,784 low-income households with pre-school aged children receiving food supplements from the Colombian Plan for Improving Food and Nutrition in Antioquia - MANA (Mejoramiento Alimentario y Nutricional de Antioquia) in the Department of Antioquia, Colombia. Included in the study was a 12-item household food security survey was collected from a cross-sectional, stratified random sample of MANA participants in which households were characterized as food secure, mildly food insecure, moderately food insecure, and severely food insecure. It was hypothesized that household food security status would be strongly associated with demographic characteristics, food expenditure variables, and food supplement consumption by children in MANA. Food insecure households were characterized by more members, older parents, and lower income (p < 0.0001). Rural residence and female head of households had higher rates of food insecurity (p < 0.01). Food insecure households had the lowest monthly expenditures food (p < 0.0001). Severely food insecure households saved the highest percentage of per capita food expenditure from consuming MANA supplements (p < 0.0001), similarly, MANA food supplement intakes were greatest in households reporting the most food insecurity (p < 0.001). The results of this study are important to describe characteristics of the population benefiting from the MANA nutrition intervention by their unique level of household food security status.
本研究的目的是探究与哥伦比亚安蒂奥基亚省2784户有学龄前儿童的低收入家庭粮食安全相关的人口和经济特征，这些家庭从安蒂奥基亚改善粮食和营养计划（MANA）领取食品补充剂。该研究纳入了一项针对MANA参与者的横断面分层随机样本进行的包含12个项目的家庭粮食安全调查，其中家庭被划分为粮食安全、轻度粮食不安全、中度粮食不安全和重度粮食不安全。研究假设，MANA中家庭粮食安全状况将与人口特征、食品支出变量以及儿童的食品补充剂消费密切相关。粮食不安全家庭的特点是家庭成员更多、父母年龄更大且收入更低（p<0.0001）。农村居住和女性户主家庭的粮食不安全率更高（p<0.01）。粮食不安全家庭的每月食品支出最低（p<0.0001）。重度粮食不安全家庭从消费MANA补充剂中节省的人均食品支出比例最高（p<0.0001），同样，报告粮食不安全程度最高的家庭中MANA食品补充剂摄入量最大（p<0.001）。本研究结果对于按家庭粮食安全状况的独特水平描述受益于MANA营养干预的人群特征具有重要意义。
