背景南非目前正在经历营养转型，南非儿童超重和肥胖正在增加。城市化和其他健康决定因素导致体育活动减少和不健康饮食，增加了不良慢性健康状况的风险。本研究旨在提供证据的有效性，以学校为基础的干预研究，针对饮食和体育活动，以预防儿童和青少年超重和/或肥胖。方法采用混合方法研究设计，分为两个阶段。第1阶段，即定性启发研究阶段，将为定量干预阶段（第2阶段）的发展提供信息，包括基于关键利益相关者的投入的群集随机试验。这项研究将在南非夸祖鲁-纳塔尔的iLembe区的16所政府资助的小学进行。这项研究将针对四年级和七年级的学生、他们的父母、生活指导教育工作者、学校校长和学校管理机构的成员。将在2020年3月基线和2020年10月研究结束时对两个研究组的主要目标（BMI Z评分）和次要目标（饮食和体力活动方面的知识、态度和行为变化）进行评估。讨论本研究将是一种新型的混合方法/随机对照试验设计，重点是在夸祖鲁-纳塔尔超重和肥胖患病率迅速增加的背景下，对饮食、体育活动、学校和家庭进行干预。为了鼓励改变行为和管理营养不良，必须考虑开展包括饮食和体育活动在内的教育，这是一项重要战略。营养教育不仅限于传播食品信息，还包括满足参与者的需求，增强和鼓励决策和选择食品的能力，根据现有资源和文化界限改变营养态度、信仰和影响。
Background South Africa is currently undergoing a nutrition transition, and overweight and obesity is on the increase in South African children. Urbanization and other health determinants have led to reduced physical activity and unhealthy eating that have increased the risk of adverse chronic health conditions. This study aims to provide evidence of the effectiveness of a school-based intervention study that targets diet and physical activity for the prevention of child and adolescent overweight and/or obesity. Methods We will employ a mixed method study design which is divided into two phases. Phase 1, namely the qualitative elicitation research phase will inform the development of the quantitative intervention phase (phase 2), consisting of a cluster-randomized trial, based on input from key stakeholders. The study will be undertaken in 16 government-funded primary schools in the iLembe district of KwaZulu-Natal, South Africa. The study will target learners in Grades 4 and 7, their parents, Life Orientation educators, school principals and members of school governing bodies. Assessment for the primary objective (BMI Z scores), and the secondary objectives (change in knowledge, attitudes and behaviours regarding diet and physical activity) in both study arms will be conducted at baseline in March 2020 and at the end of the study in October 2020. Discussion The study will be a novel combined mixed methods/RCT design that focuses on diet, physical activity school and family-based interventions in the context of rapidly increasing overweight and obesity prevalence in KwaZulu-Natal. To encourage behaviour change and management of malnutrition, education including diet and physical activity, is an important strategy that must be considered. Nutrition education extends beyond the dissemination of food information; it includes addressing the needs of participants, empowers and encourages decision-making and choice of foods, change in nutrition attitudes, beliefs and influences based on resources available and within cultural boundaries.
