Parenting regarding TV viewing and overweight in Latino preschool children

描述（由申请人提供）：Darcy Thompson 博士是一位普通儿科医生，接受过流行病学和研究方法方面的进修培训。她的职业目标是进行跨学科研究，以确定与拉丁裔儿童超重发展相关的可改变的家庭环境因素。她的近期目标是成为一名独立调查员，拥有进行跨学科调查所需的知识、技能和初步研究，重点是了解与拉丁裔学龄前儿童超重有关的电视观看育儿实践，也称为电视观看的家长调解。看电视与超重有关，然而，父母对看电视的调节作用，例如，体重过重。与儿童超重有关的儿童电视观看规则很少受到关注，尤其是在拉丁裔家庭中。由于文化和社会因素，拉丁裔家庭中父母对电视观看的调节及其与超重的关系可能有所不同。该提案概述了 3 项研究，有 4 个目标。第一项研究分析了现有数据库，以评估低收入拉丁裔儿童观看电视的程度因原籍国和文化适应程度而异，以及电视观看是否与父母对电视观看的中介有关（AIM 1）；并确定低收入拉丁裔家庭中父母对电视观看、儿童电视观看和体重指数随时间的调节之间的关系（AIM 2）。第二项研究使用定性方法开发了一种工具，用于衡量低收入学龄前儿童的墨西哥裔美国母亲对电视观看的父母信念以及父母对电视观看的调解（AIM 3）。在第三项研究中，汤普森博士将对学龄前儿童的低收入墨西哥裔美国母亲进行一项基于临床的研究，以评估新仪器的心理测量学，并确定父母信念与电视观看、儿童电视观看、儿童饮食和体重指数（AIM 4）的中介之间的关联。为了开展这项工作，汤普森博士将获得有关育儿以及媒体和肥胖研究方法论问题的知识。她将培养进行文化研究和使用先进分析技术的技能。培训和研究将在约翰霍普金斯大学进行，并由多元化且强大的导师团队指导。 公众相关性：了解低收入拉丁裔学龄前儿童超重发展的背景影响对于设计基于证据的文化干预措施非常重要。这项拟议的工作将为针对拉丁裔学龄前儿童的超重干预措施的设计提供信息，通过增强我们对父母观看电视在超重发展中的中介作用的理解。

DESCRIPTION (provided by applicant): Dr. Darcy Thompson is a general pediatrician with fellowship training in epidemiology and research methods. Her career goal is to conduct interdisciplinary research that identifies modifiable family environmental factors related to the development of overweight in Latino children. Her immediate goal is to become an independent investigator who has the knowledge, skills, and preliminary research necessary to conduct interdisciplinary investigations focused on understanding parenting practices regarding TV viewing, also called parental mediation of TV viewing, in relation to overweight in Latino preschoolers. TV viewing is associated with overweight, however, the role of parental mediation of TV viewing, e.g. having rules about child TV viewing, in relation to childhood overweight has received little attention, especially in Latino families. Parental mediation of TV viewing and its relation with overweight may differ in Latino families due to cultural and social factors. This proposal outlines 3 studies with 4 aims. The 1st study analyzes an existing database to evaluate the extent to which TV viewing in low-income Latino children varies by country of origin and acculturation and if TV viewing is associated with parental mediation of TV viewing (AIM 1); and to determine the relationship between parental mediation of TV viewing, child TV viewing, and BMI in low-income Latino families over time (AIM 2). The 2nd study uses qualitative methods to develop a tool to measure parental beliefs about TV viewing and parental mediation of TV viewing in low-income Mexican-American mothers of preschoolers (AIM 3). In the 3rd study, Dr. Thompson will conduct a clinic based study of low-income Mexican-American mothers of preschoolers to evaluate the psychometrics of new instruments and determine associations among parental beliefs and mediation of TV viewing, child TV viewing, child diet and BMI (AIM 4). To conduct this work, Dr. Thompson will acquire knowledge on parenting and methodological issues of media and obesity research. She will develop skills in conducting culturally informed research and using advanced analytical techniques. Training and research will take place at Johns Hopkins University with guidance from a diverse and strong team of mentors. PUBLIC RELEVANCE: Understanding contextual influences on the development of overweight in low-income Latino preschoolers is important to the design of evidence-based culturally competent interventions. This proposed work will inform the design of overweight interventions targeting Latino preschoolers by enhancing our understanding of the role of parental mediation of TV viewing in the development of overweight.
