这项研究将测试初级保健提供者和营养师对体重指数(BMI)为≥85和≤97百分位数的2-8岁儿童进行动机访谈的效果。来自美国儿科学会、儿科办公室设置研究网络的43名医生被分配到三组中的一组。第1组(常规护理)在基线、1年和2年随访时测量BMI百分位数，并接受标准的健康教育材料。第二组提供者在第一年提供三次积极的MI咨询服务，并在第二年额外提供一次“助推器”访问。第三组增加六次由训练有素的营养师提供的MI咨询课程。主要结果是儿童在2年后的BMI百分位数。次要结果包括父母报告孩子的屏幕时间、体力活动、水果和蔬菜的摄入量以及含糖饮料。我们招募了584名符合条件的儿童，他们的平均BMI百分位数为92.0，平均年龄为5.1。队列中57%是女性。近70%的父母报告家庭年收入为4万≥美元，39%的父母至少受过大学教育。这群人中63%是白人，23%是西班牙裔，7%是黑人，7%是亚洲人。父母对孩子达到健康体重的信心平均为8分(满分10分)。到目前为止，这项研究的几个方面可以为类似的努力提供信息，包括我们使用志愿临床医生招募参与者的能力，以及他们愿意无偿奉献时间接受MI培训。
This study will test the efficacy of motivational interviewing (MI) conducted by primary care providers and dieticians among children ages 2-8 years old with a body mass index (BMI) ≥85th and ≤97th percentile. Forty-three practices from the American Academy of Pediatrics, Pediatric Research in Office Settings Network were assigned to one of three groups. Group 1 (usual care) measures BMI percentile at baseline, and at 1- and 2-year follow-ups and received standard health education materials. Group 2 providers deliver three proactive MI counselling sessions with a parent of the index child in Year 1 and one additional ‘booster’ visit in Year 2. Group 3 adds six MI counselling sessions from a trained dietician. The primary outcome is the child’s BMI percentile at 2-year follow-up. Secondary outcomes include parent report of the child’s screen time, physical activity, intake of fruits and vegetables, and sugar-sweetened beverages. We enrolled 584 eligible children whose mean BMI percentile was 92.0 and mean age of 5.1. The cohort was 57% female. Almost 70% of parents reported a household income of ≥$40 000 per year, and 39% had at least a college education. The cohort was 63% White, 23% Hispanic, 7% Black and 7% Asian. Parent self-reported confidence that their child will achieve a healthy weight was on average an 8 (out of 10). To date, several aspects of the study can inform similar efforts including our ability to use volunteer clinicians to recruit participants and their willingness to dedicate their time, without pay, to receive training in MI.
