To assess the nutritional content and contribution to recommended nutrient intakes of the menu offerings in diverse daycare centers serving low-income urban families in Guatemala City.
An observational study design was used to record all food and drink items offered to children attending four daycare centers on 5 different days of the week to represent a typical week (20 d). Direct recording of menus, weighing of ingredients used, and the preparation of dishes and drinks were undertaken. Estimated energy, macronutrients, and eight selected micronutrients were assessed and related to the Food and Agriculture Organization/World Health Organization recommended nutrient intakes. Nutrient densities and critical densities were computed. The diet was also assessed separately by meal time. Top sources of energy and nutrients were identified.
The quantity and quality of food items provided at the four daycare centers examined varied greatly. For some nutrients, the recommended nutrient intakes were already accounted for by the food consumed from the institutional fare. As expected, those centers with more meal times covered on their menus had a greater degree of coverage of requirements. Adequacy ratios were above 100% for eight, seven, three, and one of nine nutrients examined for centers A, B, C, and D, respectively. When intakes were compared using nutrient density, all significances were abolished across all nutrients of interest.
The present descriptive analysis provides the basis for suggesting reforms at the specific centers and for understanding the generic challenges and opportunities across the system for low-income attendees in Guatemala City.
评估危地马拉城为低收入城市家庭提供服务的多元化日托中心的菜单提供物的营养含量和对推荐营养素摄入量的贡献。
采用观察性研究设计,记录了每周 5 天、每天 4 家日托中心为儿童提供的所有食物和饮料,以代表典型的一周(20 天)。对菜单进行直接记录、对所用食材进行称重、以及对菜肴和饮料进行准备。评估了估计的能量、宏量营养素和 8 种选定的微量营养素,并将其与粮农组织/世界卫生组织的推荐营养素摄入量进行了关联。计算了营养素密度和关键密度。还按用餐时间分别评估了饮食。确定了能量和营养素的主要来源。
在所检查的 4 家日托中心,提供的食物数量和质量差异很大。对于一些营养素,机构提供的食物已经涵盖了推荐的营养素摄入量。不出所料,那些在菜单上涵盖更多用餐时间的中心,其需求的涵盖程度更高。对于中心 A、B、C 和 D,分别有 8、7、3 和 1 种营养素的适宜比超过 100%。当使用营养素密度比较摄入量时,所有感兴趣的营养素的所有显著性都被消除。
本描述性分析为建议特定中心进行改革以及了解危地马拉城低收入参与者系统的普遍挑战和机遇提供了基础。
