To assess the effectiveness of the Melbourne Infant Feeding, Activity and Nutrition Trial (InFANT) Program according to maternal education and age.
A cluster-randomised controlled trial involving 542 mother/infant pairs from 62 existing first-time parent groups was conducted in 2008 in Melbourne, Australia. The intervention involved 6 × 2-hour dietitian-delivered sessions, DVD and written resources from infant age 4-15 months. Outcomes included infant diet (3 × 24 h diet recalls), physical activity (accelerometry), television viewing and body mass index. We tested for moderation by maternal education (with/without a University degree) and age (< 32 and ≥ 32 years). The trial was registered with the ISRCTN Register (identifier 81847050).
Interaction effects with the treatment arm were observed for maternal education and age. The intervention effects on vegetable (positive effect) and sweet snack consumption (negative effect) were greater in children with higher educated mothers while intervention effects on water consumption (positive effect) were greater in infants with lower educated mothers. The intervention was also more effective in increasing both vegetable and water consumption in infants with mothers aged < 32 years.
Child obesity prevention interventions may be differentially effective according to maternal education and age. Evidence of differential effects is important for informing more sensitively targeted/tailored approaches.
根据母亲的教育程度和年龄评估墨尔本婴儿喂养、活动和营养试验（InFANT）计划的效果。
这是一项 2008 年在澳大利亚墨尔本进行的、涉及 62 个首次生育小组的 542 对母婴的集群随机对照试验。干预措施包括 6 次由营养师进行的 2 小时课程、婴儿 4-15 个月的 DVD 和书面资源。结果包括婴儿饮食（3 次 24 小时饮食回忆）、身体活动（加速度计）、看电视和体重指数。我们根据母亲的教育程度（是否有大学学位）和年龄（<32 岁和≥32 岁）进行了调节测试。该试验在 ISRCTN 登记处（标识符 81847050）注册。
干预组与母亲教育程度和年龄存在交互作用。在接受高等教育的母亲的孩子中，蔬菜（正面效果）和甜点心（负面效果）的摄入量增加，而在接受低等教育的母亲的孩子中，水的摄入量（正面效果）增加。该干预措施还增加了母亲年龄<32 岁的婴儿蔬菜和水的摄入量。
儿童肥胖预防干预措施可能根据母亲的教育程度和年龄而产生不同的效果。差异效应的证据对于为更敏感的针对性/定制方法提供信息非常重要。
