Investigating how gender differences can vary by parental acculturation

项目总结 儿童的食物消费是肥胖的直接决定因素，这是一种严重的健康状况 对短期和长期发病率的影响。在美国的墨西哥移民的子女尤其是 易患肥胖症，男孩比女孩更容易患肥胖症。 这一模式激励了当前的研究，它将实现三个目标，从而产生新的知识 关于墨西哥移民子女在食物消费方面的性别差异。我们将首先调查 食物消费总量的性别差异，饮食文化适应的两个指标，以及六个指标 (联合国)健康饮食，以及家庭在促进性别差异方面的作用。到时候我们会的 调查墨西哥移民的子女在哪里消费食物和食物是否存在性别差异 这些差异是否有助于解释食物消费的性别差异。最后，我们将调查 孩子们在吃什么食物以及在哪里吃食物的性别差异是否因父母而异 文化适应。这项研究的目的是基于一个框架，该框架借鉴生态系统理论来 组织移民家庭育儿动态与移民文化适应研究 父母和他们的孩子。 目标将通过对3580名墨西哥移民年龄的子女的数据进行新颖的分析来实现 6-18岁，参加2003/4-2017/18年度全国健康和营养检查调查(NHANES)。 这项研究是最全面、最具全国代表性的定量食物饮食数据来源， 还包括大量墨西哥移民子女的样本。我们将采用三种分析方法。 OLS回归模型将估计研究中食物消费指标的性别差异，以及 每天在不同环境(家庭、餐馆、学校和其他地点)消费的饭菜数量。在以下范围内- 模型之间的差异将被用来更好地理解产生性别差异的家庭层面的机制 儿童在什么地方和什么地方吃食物。来分析孩子们在哪里的差异程度 食物消费有助于解释食物消费的性别差异，我们将利用结构方程 模特们。同样的建模策略也将用于测试结构方程模型中的路径 父母的文化适应程度不同。 项目团队(Frisco、Dondero和Van Hook)与 NHANES和实质性的专业知识领域使它们非常适合完成这项研究及其目标。

PROJECT SUMMARY Children's food consumption is a proximate determinant of obesity, a health condition with serious implications for short- and long-term morbidity. Children of Mexican immigrants in the U.S. are especially vulnerable to obesity, with boys even more at risk than girls. This pattern motivates the current study, which will accomplish three aims that will produce new knowledge about gender differences in food consumption among children of Mexican immigrants. We will first investigate gender differences in total food consumed, two measures of dietary acculturation, and six measures of (un)healthy eating, along with the role that families have in fostering gender differences. We will then investigate whether there are gender differences in where children of Mexican immigrants consume food and whether these differences help to explain gender differences in food consumption. Finally, we will investigate whether gender differences in what food children consume and where they consume it varies by parental acculturation. The study's aims are motivated by a framework that draws from ecological systems theory to organize research about parenting dynamics within immigrant families and the acculturation of immigrant parents and their children. Aims will be accomplished through novel analysis of data from 3,580 children of Mexican immigrants ages 6–18 who participated in the 2003/4-2017/18 National Health and Nutrition Examination Surveys (NHANES). This study is the most comprehensive, nationally representative source of quantitative food dietary data that also includes a large sample of children of Mexican immigrants. We will employ three analytic approaches. OLS regression models will estimate gender differences in the study's food consumption measures and the number of daily meals consumed in different settings (home, restaurants, schools and other locations). Within- between models will then be used to better understand family-level mechanisms producing gender differences in what and where children consume food. To analyze the degree to which differences in where children consume food help to explain gender differences in food consumption, we will utilize structural equation models. This same modeling strategy will also be used to test whether paths in the structural equation models differ by parental acculturation level. The project team's (Frisco, Dondero, and Van Hook) collaborative history, methodological expertise with the NHANES and substantive areas of expertise make them ideally suited to accomplish this study and its aims.
