Many Latinos in the U.S. do not meet dietary recommendations for healthy eating. Family systems theory posits that the family environment affects family members' dietary behaviors. Moreover, research suggests that children's acculturation is associated with Latina mothers' dietary intake and behaviors.
This longitudinal study examined the effect of the family environment on Latina mothers' dietary intake and behaviors. Further, we examined whether these effects differed between mothers of assimilated versus bicultural children.
Secondary data were collected at three time points (baseline, and four and 10 months' post-baseline) from 162 culturally traditional and bicultural Latina mothers residing in Imperial County, California, U.S. Participants were enrolled in the delayed treatment group of a randomized controlled trial. Mothers' daily fruit, vegetable, and sugary beverages intake, percent of calories from fat, weekly away-from-home eating, and percent of weekly grocery dollars spent on fruits and vegetables were examined. The family environment was measured by family expressiveness and family interactions around food. Separate autoregressive cross-lagged models examined the effects of the family environment on dietary outcomes, adjusting for sociodemographic variables. Interactions between the family environment and children's acculturation were also tested.
Less positive family interactions around food at baseline predicted more frequent away-from-home eating four months later among mothers of assimilated children. More family expressiveness at four months predicted more grocery dollars spent on fruits and vegetables at ten months among mothers of bicultural children.
Findings suggest the importance of a positive family environment on socially-bound dietary behaviors (e.g., away-from-home eating) exhibited by the mother. Family interventions aimed at improving dietary intake and associated behaviors should promote a positive family environment around food and consider the moderating role of children's acculturation.
许多在美国的拉丁裔人不符合健康饮食的饮食建议。家庭系统理论认为，家庭环境会影响家庭成员的饮食行为。此外，研究表明，儿童的文化适应与拉丁裔母亲的饮食摄入和行为有关。
本纵向研究考察了家庭环境对拉丁裔母亲饮食摄入和行为的影响。此外，我们还研究了这些影响在同化和双文化儿童的母亲之间是否存在差异。
从美国加利福尼亚州帝国县的 162 位文化传统和双文化的拉丁裔母亲中收集了三个时间点（基线以及基线后四个月和十个月）的二次数据。参与者被纳入一项随机对照试验的延迟治疗组。检查了母亲的每日水果、蔬菜和含糖饮料摄入量、脂肪卡路里百分比、每周外出就餐和每周用于水果和蔬菜的杂货店支出百分比。家庭环境通过家庭表达和围绕食物的家庭互动来衡量。分别通过自回归交叉滞后模型，调整社会人口统计学变量，考察家庭环境对饮食结果的影响。还测试了家庭环境与儿童文化适应之间的相互作用。
基线时家庭围绕食物的互动不那么积极，预示着同化儿童的母亲四个月后外出就餐更频繁。四个月时家庭表达能力更强，预示着十个月时双文化儿童的母亲在水果和蔬菜上的杂货店支出更多。
研究结果表明，积极的家庭环境对母亲表现出的与社会相关的饮食行为（例如外出就餐）的重要性。旨在改善饮食摄入和相关行为的家庭干预措施应促进围绕食物的积极家庭环境，并考虑儿童文化适应的调节作用。
