Studies suggest that caregivers influence children's dietary behaviors through role modeling in child-care environments. However, few studies have examined role modeling by caregivers and child-care center policies. This cross-sectional study evaluated the associations between child-care center policies about staff eating practices and caregivers' eating behaviors during mealtime interactions with children. Data were collected in 2008-2009 at 50 North Carolina child-care centers. Caregivers (n=124) reported about modeling healthy eating behaviors to children, trained research staff observed caregivers' (n=112) eating behaviors in classrooms, and directors reported about the presence/absence of center policies on staff eating practices. About 90% of caregivers reported modeling healthy eating behaviors to children. At 80% of centers, caregivers were observed modeling healthy dietary behaviors (eg, sitting with or eating same foods as children), but at fewer centers they were observed consuming unhealthy foods (eg, fast foods, salty snacks: 25%; and sugar-sweetened beverages: 50%). Although no substantial associations were observed between caregiver behaviors and center policies, effect size estimates suggest differences that may be of clinical significance. For example, caregivers were observed modeling healthy dietary behaviors more frequently at centers that had written policies about staff discouraging unhealthy foods for meals/snacks and having informal nutrition talks with children at meals. However, caregivers were observed consuming unhealthy foods and sugar-sweetened beverages more often at centers with policies that promoted healthier foods for meals/snacks. Future research should build on this study by using larger samples to understand why healthy food policies in child-care centers may not translate to eating practices among caregivers.
研究表明,在儿童保育环境中,照顾者通过榜样作用影响儿童的饮食行为。然而,很少有研究检查照顾者的榜样作用和儿童保育中心的政策。本横断面研究评估了儿童保育中心关于员工饮食实践的政策与照顾者在与儿童共进餐时的饮食行为之间的关联。数据于 2008-2009 年在北卡罗来纳州的 50 家儿童保育中心收集。照顾者(n=124)报告了向儿童树立健康饮食行为榜样的情况,经过培训的研究人员观察了照顾者(n=112)在教室中的饮食行为,主任报告了中心关于员工饮食实践的政策的有无情况。约 90%的照顾者报告向儿童树立了健康饮食行为榜样。在 80%的中心,观察到照顾者树立了健康的饮食行为榜样(例如,与儿童坐在一起或吃相同的食物),但在较少的中心观察到他们食用不健康的食物(例如,快餐、咸味零食:25%;含糖饮料:50%)。尽管照顾者的行为与中心政策之间没有观察到实质性关联,但效应量估计表明存在可能具有临床意义的差异。例如,在有书面政策规定员工劝阻不健康食物作为餐点/零食、在用餐时与儿童进行非正式营养谈话的中心,照顾者更有可能树立健康的饮食行为榜样。然而,在提倡更健康的食物作为餐点/零食的中心,照顾者更有可能食用不健康的食物和含糖饮料。未来的研究应该在此基础上进行,使用更大的样本量来理解为什么儿童保育中心的健康食品政策可能无法转化为照顾者的饮食行为。
