We developed and tested the feasibility of a behavioral intervention that utilizes clinic and home visitations to reduce overweight in preschool children above the 95(th) BMI percentile. Five families of preschool children ages 2 to 5 years with a BMI above the 95(th) percentile and one overweight parent were enrolled in a 24-week behavioral weight management program. Phase I, Intensive Treatment included 12 weekly sessions, alternating group-based clinic sessions and home settings. Phase II, Maintenance included 6 bi-weekly sessions alternating between the clinic and home setting. Treatment focused on teaching parents to use behavioral child management strategies to systematically implement dietary changes across beverages and snacks, meals, and to increase physical activity. Home visits focused on modifying the home food environment and in vivo use of child behavior management skills. Treatment targeted either weight maintenance or a small weight loss. Outcome measures were obtained at baseline (week 0), end of treatment (week 24), and at 6 month follow up after treatment ended (week 52). Three participants completed 24 weeks of treatment and were compared to two participants who did not complete treatment. Treatment completers showed reductions in zBMI and percent overweight while two noncompleting families increased their percent overweight and maintained their zBMI at 6 month follow up. These results suggest initial support for development of a behavior-based weight management intervention for obese preschool children and their families. Intervention targets appear to be enhanced by the inclusion of home visitations, in which food environments are changed to facilitate treatment goals.
我们开发并测试了一种行为干预措施的可行性,该措施利用诊所和家访来降低BMI百分位高于第95位的学龄前儿童的超重情况。五个2至5岁、BMI高于第95百分位且有一位超重家长的学龄前儿童家庭参与了一项为期24周的行为体重管理计划。第一阶段,强化治疗包括每周12次课程,在基于小组的诊所课程和家庭环境之间交替进行。第二阶段,维持治疗包括每两周6次课程,在诊所和家庭环境之间交替进行。治疗重点是教导家长使用行为儿童管理策略,系统地在饮料、零食、餐食方面实施饮食改变,并增加身体活动。家访重点是改变家庭食物环境以及在实际中运用儿童行为管理技能。治疗目标是维持体重或小幅减重。在基线(第0周)、治疗结束时(第24周)以及治疗结束后6个月随访(第52周)时获取结果测量数据。三名参与者完成了24周的治疗,并与两名未完成治疗的参与者进行比较。完成治疗者的zBMI和超重百分比有所降低,而两个未完成治疗的家庭在6个月随访时超重百分比增加且zBMI维持不变。这些结果为针对肥胖学龄前儿童及其家庭开展基于行为的体重管理干预措施提供了初步支持。家访的纳入似乎增强了干预目标,在家访中改变食物环境以促进治疗目标的实现。
