To assess the impact of an early childhood obesity prevention intervention "Healthy Caregivers-Healthy Children" (HC2) on dietary patterns and body mass index percentile (PBMI) over 2 school years.
Randomized controlled trial.
Childcare centers.
Low-income families.
Intervention centers (N = 12) received HC2 which consisted of (1) menu modifications, (2) a healthy eating and physical activity curriculum for children, and (3) a parent curriculum for healthy meal preparation, reinforced through a role-modeling curriculum. Control centers (N = 16) received an injury prevention/safety intervention.
Child PBMI and parent report of child's consumption of fruits/vegetables and unhealthy food.
Confirmatory factor analysis verified the psychometric properties of factor scores for children's consumption of fruits/vegetables and unhealthy food. Growth curve analysis assessed the impact of HC2 on change in consumption of fruits/vegetables and unhealthy food and PBMI over 2 school years.
Children in the intervention group (n = 754) had a negative slope (β = -1.95, standard error [SE] = 0.97, P = .04), indicating less increase in PBMI versus control children (n = 457). Stratified analyses showed that obese children in the intervention arm had a significantly higher increase in fruit/vegetable consumption versus control group obese children (β = 0.24, SE = 0.08, P = .003).
The HC2 intervention resulted in the maintenance of healthy PBMI over 2 preschool years among low-income multiethnic children. These findings support efforts to implement healthy weight programs in the childcare setting.
评估一项幼儿肥胖预防干预措施“健康照顾者-健康儿童”（HC2）在两个学年中对饮食模式和体重指数百分位数（PBMI）的影响。
随机对照试验。
儿童保育中心。
低收入家庭。
干预中心（N = 12）接受HC2干预，该干预包括：（1）菜单调整；（2）针对儿童的健康饮食和体育活动课程；（3）通过榜样示范课程强化的家长健康膳食准备课程。对照中心（N = 16）接受伤害预防/安全干预。
儿童PBMI以及家长报告的儿童水果/蔬菜和不健康食品的摄入量。
验证性因素分析验证了儿童水果/蔬菜和不健康食品摄入量因素得分的心理测量特性。生长曲线分析评估了HC2对两个学年中水果/蔬菜和不健康食品摄入量变化以及PBMI的影响。
干预组儿童（n = 754）的斜率为负（β = -1.95，标准误[SE] = 0.97，P = .04），表明与对照组儿童（n = 457）相比，PBMI的增加较少。分层分析表明，干预组中的肥胖儿童与对照组肥胖儿童相比，水果/蔬菜摄入量的增加显著更高（β = 0.24，SE = 0.08，P = .003）。
HC2干预使低收入多民族儿童在两个学前学年中维持了健康的PBMI。这些发现支持在儿童保育环境中实施健康体重计划的努力。
