The study presents the immediate post-intervention results of Kids and Adults Now - Defeat Obesity!, a randomized controlled trial to enhance healthy lifestyle behaviors in mother-preschooler (2-5 years old) dyads in North Carolina (2007-2011). The outcomes include change from baseline in the child's diet, physical activity and weight, and in the mother's parenting behaviors, diet, physical activity, and weight.
The intervention targeted parenting through maternal emotion regulation, home environment, feeding practices, and modeling of healthy behaviors. 400 mother-child dyads were randomized.
Mothers in the intervention arm, compared to the control arm, reduced instrumental feeding (-0.24 vs. 0.01, p<0.001) and TV snacks (-.069 vs. -0.24, p=0.001). There were also improvements in emotional feeding (p=0.03), mother's sugary beverage (p=0.03) and fruit/vegetable (p=0.04) intake, and dinners eaten in front of TV (p=0.01); these differences were not significant after adjustment for multiple comparisons.
KAN-DO, designed to maximize the capacity of mothers as agents of change, improved several channels of maternal influence. There were no group differences in the primary outcomes, but differences were observed in the parenting and maternal outcomes and there were trends toward improvement in the preschoolers' diets. Long-term follow-up will address whether these short-term trends ultimately improve weight status.
本研究呈现了“儿童和成人现在-战胜肥胖！”（Kids and Adults Now - Defeat Obesity!）的即时干预结果，这是一项在北卡罗来纳州（2007-2011 年）针对母亲-学龄前儿童（2-5 岁）二人组的随机对照试验，旨在增强健康的生活方式行为。结果包括儿童饮食、身体活动和体重以及母亲育儿行为、饮食、身体活动和体重的基线变化。
该干预针对母亲的情绪调节、家庭环境、喂养行为以及健康行为的示范，目标是育儿行为。400 对母婴二人组被随机分组。
与对照组相比，干预组的母亲减少了工具性喂养（-0.24 对 0.01，p<0.001）和电视零食（-0.069 对-0.24，p=0.001）。在情感喂养方面也有所改善（p=0.03），母亲含糖饮料（p=0.03）和水果/蔬菜（p=0.04）的摄入量以及在电视前吃晚餐（p=0.01）；这些差异在经过多次比较调整后没有统计学意义。
KAN-DO 的设计目的是最大限度地提高母亲作为变革推动者的能力，改善了母亲的几个影响渠道。主要结果没有组间差异，但在育儿和母亲结果方面观察到差异，并且在学龄前儿童的饮食方面有改善的趋势。长期随访将解决这些短期趋势最终是否能改善体重状况。
