To test the feasibility, acceptability and preliminary impact of Parents and Tots Together (PTT), a family-based obesity prevention intervention, in Canada.
Canadian parents of preschoolers (aged 2-5 years).
Ontario Early Years centres in southwestern Ontario.
A pilot randomized controlled trial involving 48 parents who received either the PTT intervention (n = 27) or an attention-matched control home safety intervention (n = 21). To evaluate the feasibility of PTT, we assessed participant retention and outcome evaluation completion rates. To evaluate acceptability, we assessed program attendance and parents' responses to program satisfaction surveys. To evaluate preliminary impact, we assessed children's body mass index (BMI) at baseline, after intervention (end of 9-week intervention) and at 9-month follow-up. As well, at each time point, parents completed surveys assessing stress and self-efficacy related to parenting, children's sleep, activity, TV viewing and diet.
Retention rates were high in the intervention (93%) and control (84%) study arms, and 87% of parents reported that they would highly recommend PTT to a friend. At 9-month follow-up, intervention parents reported lower parenting stress (β＾ = 15.83, 95% confidence interval [CI] -29.57, -2.07, p = 0.02) and greater self-efficacy in managing their child's behaviour (β＾ = 0.16, 95% CI 0.002, 0.33, p = 0.05) than control parents. PTT had minimal influence on children's weight-related behaviours and BMI.
The results suggest that PTT can feasibly be implemented and tested in the Canadian context. Preliminary impact results suggest that the program may be effective in changing general parenting; however, program content should be modified to adequately address children's weight-related behaviours.
在加拿大测试“家长与幼儿同行”（PTT）这一基于家庭的肥胖预防干预措施的可行性、可接受性及初步影响。
加拿大2至5岁学龄前儿童的家长。
安大略省西南部的安大略省早期教育中心。
一项试点随机对照试验，涉及48名家长，其中27名家长接受PTT干预，21名家长接受注意力匹配的对照家庭安全干预。为评估PTT的可行性，我们评估了参与者留存率和结果评估完成率。为评估可接受性，我们评估了项目参与率以及家长对项目满意度调查的回复。为评估初步影响，我们在基线、干预后（9周干预结束时）以及9个月随访时评估了儿童的体重指数（BMI）。此外，在每个时间点，家长完成了评估与育儿相关的压力和自我效能感、儿童睡眠、活动、看电视及饮食情况的调查。
干预组（93%）和对照组（84%）的留存率都很高，87%的家长表示会向朋友强烈推荐PTT。在9个月随访时，与对照组家长相比，接受干预的家长报告育儿压力更低（β＾ = 15.83，95%置信区间[CI] -29.57，-2.07，p = 0.02），且在管理孩子行为方面自我效能感更强（β＾ = 0.16，95% CI 0.002，0.33，p = 0.05）。PTT对儿童与体重相关的行为和BMI影响极小。
结果表明，PTT在加拿大背景下可以切实可行地实施和测试。初步影响结果表明，该项目可能在改变一般育儿方式方面有效；然而，项目内容应加以修改，以充分解决儿童与体重相关的行为问题。
