Low adherence to dietary guidelines and a concurrent rise of obesity-related chronic diseases emphasize the need for effective interventions to promote healthy eating. There is growing recognition that behavior change interventions should draw on theories of behavior change. Online interventions grounded in theory lead to increased effectiveness for health behavior change; however, few theory-driven social media-based health promotion interventions have been described in the literature.
The objective of this study was to describe the application of the Intervention Mapping (IM) protocol to develop an evidence-informed blog to promote healthy eating among French-Canadian mothers of preschool and school-aged children.
The following six steps of the IM protocol were performed. In Step 1, a preliminary needs assessment included a literature search on theoretical domains predicting Vegetables and Fruits intakes and Milk and Alternatives intakes in adults (ie, knowledge, beliefs about capabilities, beliefs about consequences, intention/goals) and a qualitative study including focus groups to identify female Internet users' perceptions of their use of healthy eating blogs. In Step 2, two behavioral outcomes were selected (ie, increase daily intakes of Vegetables and Fruits and Milk and Alternatives of mothers to reach Canadian dietary recommendations) and subsequently divided into six performance objectives inspired by national and international dietary recommendations such as planning for healthy meals. A matrix of change objectives was then created by crossing performance objectives with theoretical domains predicting Vegetables and Fruits intakes and Milk and Alternatives intakes in adults. Step 3 consisted of selecting theory-based intervention methods (eg, modeling and goal setting) and translating them into practical applications for the context of a dietary intervention delivered through a blog. A 6-month intervention was developed in Step 4 in which we aimed to address one performance objective per month in weekly blog publications written by a registered dietitian. For Step 5, we sought to include engagement-promoting methods (eg, peer and counselor support) to promote mothers' use of the blog and adherence to the intervention. Finally in Step 6, a randomized controlled trial has been launched to evaluate the effects of the blog on dietary behaviors of French-Canadian mothers.
The intervention study is expected to be completed in March 2018.
An intervention mapping protocol allowed for effective decision making in the development of a novel knowledge translation tool to increase adherence to dietary recommendations among mothers of preschool and school-aged children.
对饮食指南的低依从性以及与肥胖相关的慢性病的同时增加，凸显了采取有效干预措施以促进健康饮食的必要性。人们越来越认识到行为改变干预措施应借鉴行为改变理论。基于理论的在线干预可提高健康行为改变的有效性；然而，文献中很少描述基于理论驱动的社交媒体健康促进干预措施。
本研究的目的是描述干预映射（IM）协议在开发一个循证博客中的应用，该博客旨在促进法裔加拿大学龄前和学龄儿童母亲的健康饮食。
执行了IM协议的以下六个步骤。在第1步中，初步需求评估包括对预测成年人蔬菜和水果摄入量以及牛奶及替代物摄入量的理论领域进行文献检索（即知识、对能力的信念、对后果的信念、意图/目标），以及一项定性研究，包括焦点小组，以确定女性互联网用户对其使用健康饮食博客的看法。在第2步中，选择了两个行为结果（即增加母亲的蔬菜和水果以及牛奶及替代物的每日摄入量，以达到加拿大饮食建议），随后根据国家和国际饮食建议（如健康饮食计划）将其分为六个绩效目标。然后通过将绩效目标与预测成年人蔬菜和水果摄入量以及牛奶及替代物摄入量的理论领域交叉，创建了一个变化目标矩阵。第3步包括选择基于理论的干预方法（如示范和目标设定），并将其转化为通过博客进行饮食干预的实际应用。在第4步中开发了一个为期6个月的干预措施，我们的目标是在注册营养师撰写的每周博客文章中每月解决一个绩效目标。对于第5步，我们寻求纳入促进参与的方法（如同伴和顾问支持），以促进母亲对博客的使用并坚持干预措施。最后在第6步中，已启动一项随机对照试验，以评估该博客对法裔加拿大母亲饮食行为的影响。
干预研究预计于2018年3月完成。
干预映射协议有助于在开发一种新的知识转化工具时进行有效决策，以提高学龄前和学龄儿童母亲对饮食建议的依从性。
