Childhood obesity is a crucial public health issue. Early childhood is a critical time to foster the establishment of healthy eating behaviours and growth, which are partly shaped by parental feeding practices. To inform French parents of the recently updated national complementary feeding guidelines for 0-3 years (in terms of nutrition and responsive feeding as a mean to encourage infant appetite control skills and promote healthy growth), an official printed brochure was developed and nationally disseminated in 2021 by the French public health agency, Santé publique France. This randomised controlled trial aims to investigate whether the provision of guidelines through digital (smartphone application) and printed (brochure) tools (vs. the printed brochure alone, usual service) results in healthier parental feeding practices, infant eating behaviours and weight status.
This double-blinded monocentric 2-arm trial is currently conducted among first-time parents living in the area of Dijon (France) and recruited in a maternity ward. From child age 3 to 36 months (mo), an app provides a range of 106 age-adapted messages, including dietary recommendations, educational advice, recipes, and tips (intervention group only). Additionally, parents of both groups are provided with 48 messages related to child general development and the printed brochure at child age 2.7 mo. The primary outcome is the body mass index (BMI) z-score at child age 36 mo. Secondary outcome measures include a combination of online parents' reports and behavioural assessments (experimental meals) of parental feeding practices and infant eating behaviours from inclusion to 36 months of age. Analyses of covariance on these outcomes will assess the effect of the intervention, adjusted for relevant confounders. Complementary mediation and moderation analyses will be conducted. Sample size was determined to be n = 118 in each arm of the trial, plus 20% to compensate for potential attrition.
This is the first public eHealth randomised control trial in France to assess the effect of a web-based and mobile intervention targeted to first-time parents to improve child feeding practices and child growth.
This trial was registered at clinicaltrials.gov as NCT05285761 (March 18, 2022).
儿童肥胖是一个重大的公共卫生问题。幼儿期是培养健康饮食行为和生长的关键时期，而这些行为和生长在一定程度上受到父母喂养方式的影响。为了让法国父母了解最近更新的 0-3 岁儿童补充喂养指南（在营养和响应式喂养方面，作为鼓励婴儿控制食欲技能和促进健康成长的手段），法国公共卫生机构 Santé publique France 于 2021 年以官方印刷小册子的形式在全国范围内发布。这项随机对照试验旨在研究通过数字（智能手机应用程序）和印刷（小册子）工具（与仅提供印刷小册子相比，常规服务）提供指南是否会导致更健康的父母喂养方式、婴儿的饮食行为和体重状况。
这项双盲单中心 2 臂试验目前正在第戎地区（法国）的首次父母中进行，并在一家妇产科病房招募。从孩子 3 到 36 个月（mo），应用程序提供了一系列 106 个适合年龄的信息，包括饮食建议、教育建议、食谱和小贴士（仅干预组）。此外，两组的父母在孩子 2.7 mo 时还会收到与孩子一般发育相关的 48 条信息和印刷小册子。主要结局是孩子 36 个月时的体重指数（BMI）z 分数。次要结局包括从纳入到 36 个月时，父母喂养方式和婴儿饮食行为的在线父母报告和行为评估（实验餐）的综合指标。对这些结果的协方差分析将评估干预的效果，调整了相关混杂因素。试验的每个臂都确定了 n = 118 的样本量，加上 20%以弥补潜在的流失。
这是法国第一个针对首次父母的基于网络的移动干预的公共电子健康随机对照试验，旨在改善儿童喂养方式和儿童生长。
该试验在 clinicaltrials.gov 上注册为 NCT05285761（2022 年 3 月 18 日）。
