The worldwide prevalence of overweight/obesity has continued to rise over the last decades. To reverse this trend, public health authorities are exploring cost-effective interventions, especially in high-income and middle-income countries. Community gardening offers a unique opportunity for individuals to enhance physical activity levels and improve their diet. However, synthesised evidence on the short-term or long-term effectiveness and on the costs of community gardening interventions to prevent overweight/obesity remains limited. Therefore, this review will investigate: (1) the effectiveness of voluntary participation in community gardening compared with no or a control intervention on overweight/obesity and associated health outcomes, (2) effects on different subgroups of populations and (3) the costs of community gardening interventions.
We will conduct a systematic review, limited to evaluations of community gardening interventions with controlled quantitative and interrupted time series designs. To identify relevant articles, we will systematically search 12 academic and 5 grey literature databases, as well as 2 trial registers and 6 websites. Articles will then be assessed for eligibility based on a predefined set of criteria. At least two independent reviewers will assess each article for relevance, before evaluating the methodological quality and potential bias of the studies. Data relevant to the objectives of this review will be extracted and cross-validated. Any disagreements will be mediated by a third reviewer. If feasible, meta-analyses of primary outcomes (overweight/obesity, physical activity, food intake, energy intake) will be conducted. We will use the Grading of Recommendations Assessment, Development and Evaluation method to assess the overall quality of evidence.
For this review, no ethical approval is required as we will only extract and analyse secondary data. We aim to submit the final review manuscript to an open access journal for publication and disseminate results via conferences and social media.

在过去几十年里，全球超重/肥胖的患病率持续上升。为扭转这一趋势，公共卫生当局正在探索具有成本效益的干预措施，特别是在高收入和中等收入国家。社区园艺为个人提供了一个独特的机会来提高身体活动水平并改善饮食。然而，关于社区园艺干预措施预防超重/肥胖的短期或长期有效性以及成本的综合证据仍然有限。因此，本综述将调查：（1）与无干预或对照干预相比，自愿参与社区园艺对超重/肥胖及相关健康结果的有效性；（2）对不同人群亚组的影响；（3）社区园艺干预措施的成本。
我们将进行一项系统综述，仅限于对采用对照定量和中断时间序列设计的社区园艺干预措施的评估。为识别相关文章，我们将系统地搜索12个学术数据库和5个灰色文献数据库，以及2个试验注册库和6个网站。然后将根据一组预定义的标准评估文章的 eligibility。在评估研究的方法学质量和潜在偏倚之前，至少两名独立评审员将评估每篇文章的相关性。将提取与本综述目标相关的数据并进行交叉验证。任何分歧将由第三位评审员进行调解。如果可行，将对主要结局（超重/肥胖、身体活动、食物摄入量、能量摄入量）进行荟萃分析。我们将使用推荐分级评估、制定和评价方法来评估证据的整体质量。
对于本综述，无需伦理批准，因为我们仅提取和分析二手数据。我们的目标是将最终综述稿件提交给开放获取期刊发表，并通过会议和社交媒体传播结果。
