DESCRIPTION (provided by applicant): This project will examine the effects of parental income and parental time available to spend at home on children's BMI and risk of obesity. The underlying premise is that children's health outcomes, like BMI, are dependent on the inputs (like income and time available for supervision) that parents are able to devote towards 'producing1 good health outcomes. Parental income and parental time available for supervision can potentially influence BMI and obesity-risk via affecting children's food consumption patterns and exercise patterns. The main hypotheses of interest are that (I) greater parental income is negatively related to obesity risk, with effects of maternal and paternal income potentially being different; (II) greater parental time at home is negatively related to obesity-risk, with effects of maternal and paternal time potentially being different; (III) the effects of parental time and income on obesity risk vary across gender and race-ethnicity. We will use data from National Longitudinal Survey of Youth 1979 (NLSY79) linked with Children of NLSY79 (CoNLSY) to test the above hypotheses. We will control for several other demographic and socio-economic characteristics, and use appropriate estimation techniques to address the problem of underlying confounding factors that can affect both children's BMI and parental resources. We will complement the above analyses by exploring potential pathways via which parental resources affect children's BMI. Since no single dataset provides all the information we require, we will draw from several large secondary datasets for this part of the analyses. The same datasets mentioned above will be used to investigate the effects of parental time and income on weekly hours spent watching television by children. Data from the National Longitudinal Survey of Youth, 1997 (NLSY97) will be used investigate the effects of parental time and income on weekly hours of exercise undertaken by children. Finally, data from the Consumer Expenditure Survey (CES) will be used to investigate the effects of parental time and income on the family's patterns of food purchases.

描述（由申请人提供）：该项目将研究父母收入和父母在家的时间对儿童体重指数和肥胖风险的影响。基本前提是，儿童的健康结果（如体重指数）取决于父母能够致力于“产生”良好健康结果的投入（如收入和可用于监督的时间）。父母的收入和父母可用于监督的时间可能会通过影响儿童的食物消费模式和运动模式来影响体重指数和肥胖风险。感兴趣的主要假设是（I）父母收入增加与肥胖风险负相关，母亲和父亲收入的影响可能不同； (II) 父母在家时间较长与肥胖风险呈负相关，母亲和父亲时间的影响可能不同； (III) 育儿时间和收入对肥胖风险的影响因性别和种族而异。我们将使用 1979 年全国青年纵向调查 (NLSY79) 与 NLSY79 儿童 (CoNLSY) 相关的数据来检验上述假设。我们将控制其他几个人口和社会经济特征，并使用适当的估计技术来解决可能影响儿童体重指数和父母资源的潜在混杂因素的问题。我们将通过探索父母资源影响儿童体重指数的潜在途径来补充上述分析。由于没有一个数据集能够提供我们所需的所有信息，因此我们将从几个大型辅助数据集中提取数据来进行这部分的分析。上述相同的数据集将用于调查父母的时间和收入对孩子每周看电视的时间的影响。 1997 年全国青少年纵向调查 (NLSY97) 的数据将用于调查父母时间和收入对儿童每周锻炼时间的影响。最后，消费者支出调查（CES）的数据将用于调查父母的时间和收入对家庭食品购买模式的影响。
