Although positive coparenting, or how parents relate during childrearing, is known to support children's socioemotional development, the role of coparenting in supporting children's healthy eating and growth is poorly understood. This study examined associations between coparenting quality, the home food environment, and young children's body mass index (BMI). Cross-sectional data were obtained from 290 mothers and their 3-year-old children who participated in the Sprout study. Mothers who indicated they had a coparent in their household completed surveys to assess coparenting quality, food parenting practices, family mealtime routines and structure, and home food availability. Mothers also reported the foods served at two typical meals, and a healthy meal index (HMI) score was calculated to assess the nutritional quality of meals. Children's height and weight were measured and used to calculate BMI z-scores (BMIz). Mothers who reported more positive coparenting also reported providing children more guidance for healthy eating (β = 0.15, < 0.001), less use of food to control children's emotions (β = -0.15, < 0.01), less use of food as a reward (β = -0.27, < 0.01), more structured mealtimes (β = 0.22, < 0.001), and more household availability of fruits and vegetables (β = 0.11, < 0.01). Mothers who reported greater coparent agreement on childrearing also had children with lower BMIz (β = -0.11, = 0.03). Mothers who reported greater endorsement of their partner's childrearing competency had a higher mean HMI score (β = 1.82, < 0.01). Among dual-parent, highly resourced families with young children, stronger coparenting practices were associated with several food-related parenting practices that support healthy eating and weight among young children.
尽管积极的共同养育，即父母在育儿过程中的相处方式，已知有助于孩子的社会情感发展，但共同养育在支持孩子健康饮食和成长方面的作用却鲜为人知。本研究考察了共同养育质量、家庭食物环境与幼儿体重指数（BMI）之间的关联。横断面数据来自参与“萌芽研究”的290名母亲及其3岁的孩子。表示家中有共同养育者的母亲完成了调查，以评估共同养育质量、食物养育方式、家庭用餐常规和结构以及家庭食物供应情况。母亲们还报告了两顿典型餐食所提供的食物，并计算了健康饮食指数（HMI）得分，以评估餐食的营养质量。测量了孩子的身高和体重，并用于计算BMI z评分（BMIz）。报告有更积极共同养育方式的母亲也报告为孩子提供了更多健康饮食指导（β = 0.15，P < 0.001），较少用食物来控制孩子情绪（β = -0.15，P < 0.01），较少用食物作为奖励（β = -0.27，P < 0.01），用餐时间更规律（β = 0.22，P < 0.001），家庭中水果和蔬菜的供应更多（β = 0.11，P < 0.01）。报告在育儿方面有更高共同养育者一致性的母亲，其孩子的BMIz也更低（β = -0.11，P = 0.03）。报告对伴侣育儿能力有更高认可度的母亲，其HMI平均得分更高（β = 1.82，P < 0.01）。在有幼儿的双亲、资源丰富的家庭中，更强的共同养育方式与几种支持幼儿健康饮食和体重的食物相关养育方式有关。
