Abstract：
OBJECTIVE: Centre-based childcare has been identified as a promising environment for obesity prevention in early childhood, but the longitudinal relationships between attending centre-based childcare and child obesity are not well understood. The objective of this systematic review is to evaluate the longitudinal associations between centre-based childcare attendance in early childhood and child body mass index compared with other childcare settings or parental care. Subgroup analyses will also be conducted to determine if socioeconomic factors and characteristics of the childcare setting modify the relationships.
METHODS: Databases that will be searched include MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Database and Web of Science. Longitudinal prospective cohort studies, retrospective cohort studies, case-control studies and intervention trials conducted in middle-income and high-income countries will be included in the search strategy. Sensitivity and subgroup analyses will be conducted to explore factors that may modify the findings. Study selection, data extraction, risk of bias and quality of evidence assessments will be conducted independently and in duplicate by two reviewers. Risk of bias will be assessed using the Risk Of Bias In Non-randomized Studies - of Exposure tool. Meta-analysis will be conducted using random effects models to account for between-study variation. Heterogeneity across included studies will be estimated using the I2 statistic. If meta-analysis is not possible, a narrative summary will be provided. The quality of the evidence will be assessed using the Grading of Recommendations Assessment, Development and Evaluation tool.
BACKGROUND: Ethical approval is not required for this study since no data will be collected. Findings aim to inform interventions and guide efforts in childcare settings to support optimal child growth. Results will be published in a peer-reviewed journal. Results may be of relevance for childcare and public health policy, researchers, parents and healthcare practitioners.

摘要：
目标：以中心为基础的儿童保育被认为是预防儿童早期肥胖的一个有希望的环境，但是，参加中心托儿服务与儿童肥胖之间的纵向关系尚不清楚。这项系统评价的目的是评估与其他托儿机构或父母照料相比，以中心为基础的幼儿托儿服务与儿童体重指数之间的纵向关联。还将进行亚组分析，以确定儿童保育环境的社会经济因素和特征是否改变了关系。
方法：要搜索的数据库包括MEDLINE，Embase,护理和相关健康文献的累积指数，Cochrane数据库和WebofScience.纵向前瞻性队列研究，回顾性队列研究，在中等收入和高收入国家进行的病例对照研究和干预试验将纳入检索策略.将进行敏感性和亚组分析以探索可能修改结果的因素。研究选择，数据提取,偏见风险和证据质量评估将由两名审查员独立进行，一式两份。偏倚风险将使用非随机研究中的偏倚风险-暴露工具进行评估。荟萃分析将使用随机效应模型进行，以解释研究之间的差异。纳入研究的异质性将使用I2统计量进行估计。如果无法进行荟萃分析，将提供叙述性摘要。将使用建议分级评估来评估证据的质量，开发和评估工具。
背景：本研究不需要伦理批准，因为不会收集数据。研究结果旨在为儿童保育机构的干预措施和指导工作提供信息，以支持儿童的最佳成长。结果将发表在同行评审的期刊上。结果可能与儿童保育和公共卫生政策有关，研究人员,父母和医疗保健从业人员。
