The aim of these reviews is to inform the design and content of interventions to reduce obesity in young children. The behaviors that are associated with obesity/overweight have been studied extensively; however, the factors associated with these behaviors in young children (0 to 6 years) have not been systematically reviewed. Over the past few years the focus of obesity prevention has shifted to preschool children because of the high prevalence of obesity at school entry and recognition that habits formed in early life could track into adulthood. In order to develop effective interventions and change behavior, it is important to understand the factors that are associated with those behaviors. For example, we need to understand whether it would be more important to target the family, childcare settings or the wider environment and identify the most effective way of changing these energy balance related behaviors.
METHODS/DESIGN: Quantitative (intervention and observational) and qualitative literature on determinants/correlates of fruit and vegetable intake, sugar sweetened beverage and other unhealthy diet intake, and physical activity and sedentary behaviors in young children will be systematically identified, mapped and reviewed. A common search strategy (no language or period restrictions) will be used to identify papers from eight electronic databases and this will be supplemented by hand-searching. Next, studies in developed countries that examine the factors associated with these behaviors in children aged 0 to 6 years (at baseline) will be screened and mapped descriptively followed by in-depth data extraction, quality assessment and synthesis. Data from quantitative studies will be summarized using either forest plots or harvest plots and narrative synthesis, and qualitative studies using thematic analysis. Qualitative evidence will be integrated with the quantitative evidence, using a parallel synthesis approach, to provide a deeper understanding of effective strategies to influence these energy balance related behaviors.
In addition to updating and mapping current research, these reviews will be the first to comprehensively synthesize and integrate both the quantitative and qualitative evidence pertaining to determinants/correlates/barriers/facilitators of obesity related behaviors in this young age group (0 to 6 years) with the aim of informing future interventions.

本综述旨在为减少幼儿肥胖的干预措施的设计和内容提供信息。与肥胖/超重相关的行为已经得到了广泛的研究；然而，与幼儿（0 至 6 岁）相关行为的因素尚未系统地审查。在过去几年中，由于肥胖在入学时的高患病率以及认识到生命早期形成的习惯可能会持续到成年期，肥胖预防的重点已转移到学龄前儿童身上。为了制定有效的干预措施并改变行为，了解与这些行为相关的因素非常重要。例如，我们需要了解针对家庭、儿童保育环境还是更广泛的环境，以及确定改变这些与能量平衡相关行为的最有效方法，是否更为重要。
方法/设计：将系统地识别、映射和审查有关幼儿水果和蔬菜摄入量、含糖饮料和其他不健康饮食以及身体活动和久坐行为的决定因素/相关因素的定量（干预和观察）和定性文献。将使用通用搜索策略（无语言或时间限制）从八个电子数据库中确定论文，并通过手动搜索进行补充。接下来，将筛选和描述性地映射发达国家中研究 0 至 6 岁儿童（基线）与这些行为相关的因素的研究，然后进行深入的数据提取、质量评估和综合。定量研究的数据将使用森林图或收获图和叙述性综合进行总结，定性研究将使用主题分析。使用平行综合方法将定性证据与定量证据相结合，以更深入地了解影响这些与能量平衡相关行为的有效策略。
除了更新和映射当前研究外，这些综述还将首次全面综合和整合与肥胖相关行为的决定因素/相关因素/障碍/促进因素有关的定量和定性证据，目的是为未来的干预措施提供信息。
