School food environment plays a crucial role in shaping children's dietary habits and promoting healthy eating practices. The study investigated the school food environment in Temeke Municipality, Dar es Salaam, focusing on its role in promoting healthy eating among school-age children. A cross-sectional survey was conducted across four schools, with food vendors (N = 20) and teachers (N = 8) interviewed using structured questionnaires. The study aimed to assess food offerings, school oversight, and vendors' knowledge of food quality. The findings disclosed that 62.5% of the schools partially implemented school feeding guidelines, while 37.5% did not implement them. Among the surveyed schools, 37.5% had food storage facilities, 25.0% had functioning kitchens, and none had dining halls. The food environment included both healthy and unhealthy options, with 55.6% of food and beverages classified as healthy and 44.4% as unhealthy. Popular unhealthy items included samosas (95.5%), fried potato chips (87.0%), and fried mashed potato balls (73.9%). The study also compared the calorie portions of foods purchased by students with the Recommended Dietary Allowances (RDA) for different age groups. The percentage of RDA covered by these portions ranged from 8.0-19.0% for ages 5-8, 6.0-19.0% for ages 9-13, and 5.0-16.0% for ages 14-18. Furthermore, food vendors demonstrated low knowledge of food safety, hygiene, and nutrition, with only 22.0% aware of the national food guidelines. The overall food environment exposed students to unhealthy food options, with significant gaps in the implementation of health guidelines. Findings highlight the need for interventions to improve food offerings and promote healthier food choices around schools.
学校饮食环境在塑造儿童饮食习惯和促进健康饮食行为方面起着至关重要的作用。该研究调查了达累斯萨拉姆特梅克市的学校饮食环境,重点关注其在促进学龄儿童健康饮食方面的作用。在四所学校开展了一项横断面调查,使用结构化问卷对食品摊贩(N = 20)和教师(N = 8)进行了访谈。该研究旨在评估食品供应、学校监管以及摊贩对食品质量的了解情况。研究结果显示,62.5%的学校部分实施了学校供餐指南,而37.5%的学校未实施。在接受调查的学校中,37.5%有食品储存设施,25.0%有正常运转的厨房,没有一所学校有食堂。饮食环境中既有健康食品也有不健康食品,55.6%的食品和饮料被归类为健康食品,44.4%为不健康食品。常见的不健康食品包括三角饺(95.5%)、炸薯片(87.0%)和炸土豆泥球(73.9%)。该研究还将学生购买食品的卡路里含量与不同年龄组的推荐膳食摄入量(RDA)进行了比较。这些摄入量占RDA的百分比在5至8岁年龄段为8.0 - 19.0%,9至13岁年龄段为6.0 - 19.0%,14至18岁年龄段为5.0 - 16.0%。此外,食品摊贩对食品安全、卫生和营养的了解程度较低,只有22.0%的人知晓国家食品指南。整体饮食环境使学生接触到不健康的食品选择,在健康指南的实施方面存在显著差距。研究结果凸显了采取干预措施改善学校周边食品供应并促进更健康食品选择的必要性。
