目的：本研究的目的是评估课后、同伴主导的健康生活项目对居住在偏远与世隔绝的第一民族的儿童的肥胖症、自我效能感和健康生活行为知识的影响。方法：在2010-2011和2011-2012两个学年，采用平行的非等价对照臂对花园山第一民族的151名儿童进行准实验研究。在每个学年的1月至5月期间，四年级学生在高中导师的帮助下，接受为期5个月的同伴主导的干预；控制组的学生接受标准课程。主要观察指标为腰围(WC)和BMI z评分。结果：51名儿童(平均+/-SD年龄：9.7+/-0.4岁；BMI z评分：1.46+/-0.84)接受干预，对照组100名儿童接受干预。基线时，腰围(79.8比83.9 cm)、BMI z评分(1.46比1.48)和超重/肥胖率(75%比72%)在不同性别之间没有差异。干预后，干预组WC(调整后治疗效果：-2.5 cm[95%可信区间：-4.1~-0.90]；P=0.002)和BMI z评分(调整后治疗效果：-0.09[95%CI：-0.16~-0.03]；P=0.007)明显低于对照组。干预组的健康饮食选择知识也有改善(2.25%[95%CI：-0.01至6.25]；P=0.02)。自我效能感与干预后WC的变化相关(β=-7.9，P=0.03)。结论：一个课后、同伴主导的健康生活计划可以减少生活在偏远与世隔绝的第一民族的儿童的体重增加，并提高他们的健康生活知识。
OBJECTIVE: The goal of this study was to assess the efficacy of an after-school, peer-led, healthy living program on adiposity, self-efficacy, and knowledge of healthy living behaviors in children living in a remote isolated First Nation.METHODS: A quasi-experimental trial with a parallel nonequivalent control arm was performed with 151 children in Garden Hill First Nation during the 2010-2011 and 2011-2012 school years. Fourth grade students were offered a 5-month, peer-led intervention facilitated by high school mentors between January and May of each school year; students in the control arm received standard curriculum. The main outcome measures were waist circumference (WC) and BMI z score. Secondary outcome measures included healthy living knowledge and self-efficacy.RESULTS: Fifty-one children (mean +/- SD age: 9.7 +/- 0.4 years; BMI z score: 1.46 +/- 0.84) received the intervention, and 100 children were in the control arm. At baseline, WC (79.8 vs 83.9 cm), BMI z score (1.46 vs 1.48), and rates of overweight/obesity (75% vs 72%) did not differ between arms. After the intervention, the change in WC (adjusted treatment effect: -2.5 cm [95% confidence interval (CI): -4.1 to -0.90]; P = .002) and BMI z score (adjusted treatment effect: -0.09 [95% CI: -0.16 to -0.03]; P = .007) were significantly lower in the intervention arm compared to the control arm. The intervention arm also experienced improvements in knowledge of healthy dietary choices (2.25% [95% CI: -0.01 to 6.25]; P = .02). Self-efficacy was associated with the change in WC after the intervention (beta = -7.9, P = .03).CONCLUSIONS: An after-school, peer-led, healthy living program attenuated weight gain and improved healthy living knowledge in children living in a remote isolated First Nation.
