目的：评价以父母为中心对婴儿肥胖危险行为和体重指数进行干预的有效性。方法：采用整群随机对照试验，从62个首次父母组中招募542名父母及其婴儿(基线平均年龄3.8月)。在15个月的时间里，为父母提供了6次2小时的营养师培训，重点是围绕婴儿喂养、饮食、体育活动和看电视的父母知识、技能和社会支持。对照组家长收到了6份关于非肥胖主题的时事通讯；所有家长都得到了儿童健康护士的常规护理。感兴趣的主要结果是儿童饮食(3，3，24小时饮食召回)，儿童体力活动(加速计)，以及儿童看电视(家长报告)。次要结果包括BMI z评分(测量)。结果：非校正分析显示，与对照组相比，干预组儿童在4、9和20个月时摄入了较少的非核心饮料(平均差异=-4.45；95%可信区间[CI]：-7.92~-0.99；P=0.01)，也较少饮用非核心饮料(优势比=0.48；95%可信区间：0.24~0.95；P=0.034)中期干预(平均年龄9个月)。在干预结束时(平均年龄19.8个月)，干预组儿童摄入的甜食较少(平均差异=-3.69；95%CI：-6.41至-0.96；P=0.008)，每天看电视的时间较少(平均差异=-15.97：95%CI：-25.97至-5.96；P=0.002)。在水果、蔬菜、可口零食或水的摄入量、BMI z得分或体力活动方面几乎没有统计学证据。结论：这项干预导致20个月大的儿童减少了甜食摄入量和看电视的次数。
OBJECTIVE: To assess the effectiveness of a parent-focused intervention on infants' obesity-risk behaviors and BMI.METHODS: This cluster randomized controlled trial recruited 542 parents and their infants (mean age 3.8 months at baseline) from 62 first-time parent groups. Parents were offered six 2-hour dietitian-delivered sessions over 15 months focusing on parental knowledge, skills, and social support around infant feeding, diet, physical activity, and television viewing. Control group parents received 6 newsletters on nonobesity-focused themes; all parents received usual care from child health nurses. The primary outcomes of interest were child diet (3 3 24-hour diet recalls), child physical activity (accelerometry), and child TV viewing (parent report). Secondary outcomes included BMI z-scores (measured). Data were collected when children were 4, 9, and 20 months of age.RESULTS: Unadjusted analyses showed that, compared with controls, intervention group children consumed fewer grams of noncore drinks (mean difference = -4.45; 95% confidence interval [CI]: -7.92 to -0.99; P = .01) and were less likely to consume any noncore drinks (odds ratio = 0.48; 95% CI: 0.24 to 0.95; P = .034) midintervention (mean age 9 months). At intervention conclusion (mean age 19.8 months), intervention group children consumed fewer grams of sweet snacks (mean difference = -3.69; 95% CI: -6.41 to -0.96; P = .008) and viewed fewer daily minutes of television (mean difference = -15.97: 95% CI: -25.97 to -5.96; P = .002). There was little statistical evidence of differences in fruit, vegetable, savory snack, or water consumption or in BMI z-scores or physical activity.CONCLUSIONS: This intervention resulted in reductions in sweet snack consumption and television viewing in 20-month-old children.
