Although low-income children are at greater risk for overweight and obesity than their higher income counterparts, the majority of poor children are not overweight. The current study examined why such variation exists among diverse young children in poor families. Cross-sectional data were collected on 164 low-income, preschool aged children and their mothers living in two Rhode Island cities. Over half of the sample was Hispanic (55%). Mothers completed measures of family food behaviors and depression while trained assistants collected anthropometric data from children at seven day care centers and a Supplemental Nutrition Assistance Program outreach project. Multivariate analysis of covariance revealed that higher maternal depression scores were associated with lower scores on maternal presence when child eats (P < .05), maternal control of child's eating routines (P < .03), and food resource management skills (P < .01), and with higher scores on child control of snacking (P < .03) and negative mealtime practices (P < .05). Multiple regression results revealed that greater maternal presence whenever the child ate was significantly associated with lower child BMI z scores (β = .166, P < .05). Logistic regression analyses indicated that higher scores on food resource management skills reduced the odds of child overweight (odds ratios = .72-.95, P < .01). Maternal depression did not modify the relationship between family food behaviors and child weight. Overall, caregiver presence whenever a child eats, not just at meals, and better parental food resource management skills may promote healthier weights in low-income preschoolers. Further research is needed to identify the mechanisms that connect caregiver presence and food resource management skills to healthier weights for this age group.
尽管低收入家庭的儿童比高收入家庭的儿童超重和肥胖的风险更高,但大多数贫困儿童并没有超重。当前的研究探讨了贫困家庭中不同幼儿之间为何存在这种差异。收集了居住在罗德岛州两个城市的164名低收入学龄前儿童及其母亲的横断面数据。样本中超过一半是西班牙裔(55%)。母亲们完成了家庭饮食行为和抑郁情况的测量,同时训练有素的助手在七个日托中心和一个补充营养援助计划外展项目中收集了儿童的人体测量数据。多变量协方差分析显示,母亲抑郁得分较高与孩子吃饭时母亲在场得分较低(P < 0.05)、母亲对孩子饮食习惯的控制得分较低(P < 0.03)以及食物资源管理技能得分较低(P < 0.01)相关,并且与孩子吃零食的控制得分较高(P < 0.03)和用餐时的负面行为得分较高(P < 0.05)相关。多元回归结果显示,孩子每次吃饭时母亲更多在场与孩子较低的BMI z评分显著相关(β = 0.166,P < 0.05)。逻辑回归分析表明,食物资源管理技能得分较高可降低儿童超重的几率(优势比 = 0.72 - 0.95,P < 0.01)。母亲的抑郁并没有改变家庭饮食行为与孩子体重之间的关系。总体而言,照顾者在孩子进食时(不仅仅是用餐时)在场以及更好的父母食物资源管理技能可能会促进低收入学龄前儿童更健康的体重。需要进一步研究以确定将照顾者在场和食物资源管理技能与该年龄组更健康体重联系起来的机制。
