Poor dietary habits are major contributors to malnutrition globally, particularly in children living in African countries. The widespread transition from African diet of healthy indigenous foods to a nutrient-poor Western-style diet is well-documented in global societal culture.
This study aimed to assess the dietary habits and their nutritional implications among learners in public primary schools.
City of Tshwane, located in the Gauteng province of South Africa.
This was a quantitative cross-sectional study where researcher-administered questionnaire was used to collect data from 814 primary school learners in grades 4-7. Anthropometric data were also collected. The study was conducted in 10 primary schools in the City of Tshwane.
Unhealthy dietary practices were observed where consumption of refined carbohydrates, sugar-filled beverages and limited protein was prevalent. The prevalence rates for overweight and obesity were 15.1% and 11.3%, respectively. Most learners (77.4%) purchased foods from street vendors and tuckshops. Also, learners who knew about healthy eating were less likely to be underweight than those who did not (OR: 0.35; 95% CI: 0.14-0.85; = 0.020).
Poor dietary habits are demonstrated in this study and may be associated with the rising levels of overweight and obesity among the learners. The findings also showed that the school environment is the main source of exposure to unhealthy diet.
Intervention strategies, such as amendment of the national school nutrition policy, need to be implemented.
不良饮食习惯是全球营养不良的主要原因,尤其是在生活在非洲国家的儿童中。从健康的本土食物的非洲饮食向营养匮乏的西式饮食的广泛转变在全球社会文化中有充分记载。
本研究旨在评估公立小学学生的饮食习惯及其营养影响。
位于南非豪登省的茨瓦内市。
这是一项定量横断面研究,使用研究者发放的问卷从814名4至7年级的小学生中收集数据。还收集了人体测量数据。该研究在茨瓦内市的10所小学进行。
观察到不健康的饮食习惯,精制碳水化合物、含糖饮料的消费普遍,蛋白质摄入有限。超重和肥胖的患病率分别为15.1%和11.3%。大多数学生(77.4%)从街头小贩和小卖部购买食物。此外,了解健康饮食知识的学生比不了解的学生体重过轻的可能性更小(比值比:0.35;95%置信区间:0.14 - 0.85;P = 0.020)。
本研究表明不良饮食习惯可能与学生中超重和肥胖水平的上升有关。研究结果还表明学校环境是接触不健康饮食的主要来源。
需要实施干预策略,如修订国家学校营养政策。
