Regular physical activity (PA) participation has many important physical and psychological health benefits, managing and preventing over 25 chronic conditions. Being more physically active as a child is associated with being more active as an adult, but less than 10% of Canadian children are achieving the recommended PA guidelines of 60 minutes per day of moderate to vigorous PA. Parental support is a predictor of child PA, but parent intention to support child PA does not always predict enacted support. Targeting factors that assist in the sustainability of parent support behaviour of child PA may have an impact on child PA. The purpose of this study is to evaluate an intervention designed to promote habit formation of parental support (HABIT, independent variable) on child PA (dependant variable) compared with a planning and education group (PLANNING) and an education only group (EDUCATION).
The three conditions will be compared using a 6-month longitudinal randomised trial. Eligible families have at least one child aged 6-12 years who is not meeting the 2011 Canadian PA Guidelines. Intervention materials are delivered at baseline, with check-in sessions at 6 weeks and 3 months. Child's moderate-to-vigorous PA, measured by accelerometry, is assessed at baseline, 6 weeks, 3 months and 6 months as the primary outcome. At baseline and 6 months, children perform fitness testing. Parents and children complete questionnaires at all timepoints. So far, 123 families have been recruited from the Greater Victoria and surrounding area. Recruitment will be continuing through 2020 with a target of 240 families.
This protocol has been approved by the University of Victoria Human Research Ethics Board (Victoria, Canada). Results will be shared at conferences as presentations and as published manuscripts. Study findings will be made available to interested participants.

定期进行身体活动（PA）有许多重要的身心健康益处，可管理和预防 25 种以上的慢性疾病。儿童时期的身体活动量与成年后的身体活动量相关，但加拿大只有不到 10%的儿童达到每天 60 分钟中等到剧烈身体活动的推荐 PA 指南。父母的支持是儿童 PA 的一个预测因素，但父母支持儿童 PA 的意图并不总是预测实施的支持。针对有助于父母支持儿童 PA 行为可持续性的因素，可能会对儿童 PA 产生影响。本研究的目的是评估一种干预措施，该干预措施旨在促进父母支持儿童 PA 的习惯形成（自变量），并将其与计划和教育组（PLANNING）和教育组（EDUCATION）进行比较。
这三种情况将通过 6 个月的纵向随机试验进行比较。合格的家庭至少有一个 6-12 岁的孩子没有达到 2011 年加拿大 PA 指南。在基线时提供干预材料，并在 6 周和 3 个月时进行检查。通过加速度计测量儿童的中度到剧烈 PA，作为主要结局，在基线、6 周、3 个月和 6 个月时进行评估。在基线和 6 个月时，孩子进行体能测试。父母和孩子在所有时间点完成问卷。到目前为止，已经从维多利亚和周边地区招募了 123 个家庭。将继续招募，目标是 240 个家庭。
本方案已获维多利亚大学人类研究伦理委员会（加拿大维多利亚）批准。结果将以会议演讲和发表的论文形式在会议上分享。研究结果将提供给感兴趣的参与者。
