Parenting regarding TV viewing and overweight in Latino preschool children

描述（由申请人提供）：达西·汤普森博士是一名普通儿科医生，接受过流行病学和研究方法方面的奖学金培训。她的职业目标是开展跨学科研究，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的调查员，拥有必要的知识、技能和初步研究，以开展跨学科调查，重点了解关于看电视的父母做法，也称为父母对看电视的调解，与拉丁裔学龄前儿童超重有关。看电视与超重有关，然而，父母对看电视的调解作用，例如对儿童看电视的规定，与儿童超重有关，很少受到关注，特别是在拉丁美洲家庭中。由于文化和社会因素，拉丁美洲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的数据库，以评估低收入拉丁裔儿童看电视的程度因原籍国和文化适应的不同而不同，以及看电视是否与父母对看电视的调解有关（AIM 1）；并确定父母对电视观看、儿童电视观看和低收入拉丁裔家庭BMI之间的关系（AIM 2）。第二项研究采用定性方法开发了一种工具来测量低收入墨西哥裔美国学龄前儿童母亲对电视观看的父母信念和父母对电视观看的中介作用（AIM 3）。在第三项研究中，Thompson博士将对低收入的墨西哥裔美国学龄前儿童母亲进行临床研究，以评估新工具的心理测量学，并确定父母信念和电视观看，儿童电视观看，儿童饮食和BMI之间的中介关系（AIM 4）。为了开展这项工作，汤普森博士将获得有关养育和媒体和肥胖研究方法问题的知识。她将培养进行文化知情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，由一个多元化和强大的导师团队指导。

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.
