DESCRIPTION (provided by applicant): Poor diet, inactivity and obesity have been linked to increased risks for a number of chronic diseases including cancer and cardiovascular diseases. Obesity and related health risk factors present in children are likely to persist into adulthood. The proposed research will investigate the relationships between televised advertisements for food, beverages, restaurants, and public service healthy diet and physical activity (HDPA) health promotion messages, and diet, physical activity, body mass index (BMI) and obesity among children and youth. The overwhelming majority (97.8%) of food product ads seen on television by American children are of poor nutritional content, being high in either sugar, fat or sodium. Most research has assessed the effect of advertising based on 1) evidence that TV watching time correlates with poor diet and/or obesity; or, 2) small- scale natural experiments that have focused on food requests or limited specific food choices which may have low external validity. The proposed project will build substantially on the previous literature. The specific aims are threefold: 1) examine the relationship between exposure to food, beverage and restaurant advertising (measured by total product exposure and nutritional content of ads using age and race-specific ratings) and children's and youths' dietary intake patterns (i.e., consumption of specific food products/groups and food away from home including fast food), diet quality (i.e., total caloric intake, % fat and % sugar in diet and overall healthy eating index), BMI and obesity; 2) examine the relationship between exposure to HDPA health promotion ads and diet, physical activity, BMI and obesity; and 3) examine the interactions between food- related and HDPA health promotion ads and neighborhood contextual factors (i.e., food prices and restaurant, food store, and physical activity-related outlet availability) and diet, activity and BMI/obesity. To accomplish these aims, the proposed research will conduct secondary data analyses, using a unique combination of four types of data: 1) television age- and race-specific ratings data for all food, beverage, restaurant, and anti- obesity advertisements, purchased from Nielsen Media Research for 106 designated media markets; 2) detailed nutritional content information about the advertised food products, 3) local area contextual data on food prices and outlet density measures; 4) data on population dietary intake, physical activity and measured height and weight from the National Health and Nutrition Examination Survey and the Early Childhood Longitudinal Study, two nationally representative population surveys one of which is longitudinal. The proposed project represents the most comprehensive exploration to date of the relationship between food, beverage, restaurant and HDPA health promotion advertising and diet, activity and BMI. Given the serious public health risk posed by poor diet, inactivity and obesity, this research can provide important information for policymakers and public health advocates about the potential effectiveness of regulating food television advertising to children and using TV media campaigns as policy tools for improving these health outcomes. PUBLIC HEALTH RELEVANCE: The proposed research will investigate the relationships between televised advertisements for food, beverages, restaurants, and public service healthy diet and physical activity health promotion messages, and diet, physical activity, body mass index and obesity among children and youth using market-level television ratings data and nationally representative cross-sectional and longitudinal population data. Given the serious public health risks including cancer and cardiovascular diseases posed by poor diet, inactivity and obesity, this research can provide important information for policymakers and public health advocates about the potential effectiveness of regulating food television advertising to children and using TV media campaigns as policy tools for improving these health outcomes.

描述（由申请人提供）：饮食不良，不活动和肥胖与多种慢性疾病在内的风险增加有关，包括癌症和心血管疾病。儿童存在的肥胖和相关的健康危险因素可能会持续到成年。拟议的研究将调查有关食品，饮料，餐馆，公共服务健康饮食和身体活动（HDPA）健康促进信息，饮食，体育锻炼，体重指数（BMI）以及儿童和青少年的饮食，身体活动，体重指数（BMI）和肥胖之间的电视广告之间的关系。美国儿童在电视上看到的绝大多数食品广告（97.8％）的营养含量不佳，糖，脂肪或钠含量很高。大多数研究都根据1）证据评估了广告的效果，表明电视观看时间与饮食和/或肥胖症差相关；或2）小规模的自然实验，这些实验集中在食品请求或可能具有较低外部有效性的特定食物选择上。拟议的项目将基于以前的文献基本上建立。具体目的是三个方面：1）检查接触食品，饮料和餐厅广告之间的关系（通过使用年龄和种族特定评级的全面暴露和ADS的营养含量来衡量），儿童和青年的饮食摄入量模式（即，饮食中的特定食品/饮食中的特定食品/饮食），饮食中的饮食和饮食量（即饮食中的特定食品/饮食），饮食中的饮食量和饮食量（即，饮食中的饮食），饮食中的饮食量和饮食效果（即饮食中），饮食量和饮食量（即饮食中），饮食中的饮食量和饮食量很高， BMI和肥胖； 2）检查暴露于HDPA健康促进广告与饮食，体育锻炼，BMI和肥胖之间的关系； 3）检查食品相关和HDPA健康促进广告与邻里背景因素（即食品价格和餐厅，食品商店以及与体育锻炼相关的出口可用性）之间的相互作用）以及饮食，活动和BMI/肥胖症。为了实现这些目标，拟议的研究将使用四种类型的数据的独特组合进行次要数据分析：1）所有食品，饮料，餐厅和反肥胖广告的电视年龄和种族特定的评级数据，从尼尔森媒体研究中购买了106个指定媒体市场； 2）有关广告食品的详细营养内容信息，3）有关食品价格和出口密度措施的局部环境数据； 4）有关人口饮食摄入，体育锻炼以及国家健康和营养检查调查的身高和体重的数据，以及幼儿纵向研究，两项全国代表性的人口调查中，其中一个是纵向的。拟议的项目代表了食品，饮料，餐厅和HDPA健康促进广告和饮食，活动和BMI之间关系迄今为止最全面的探索。鉴于饮食不良，不活动性和肥胖带来的严重公共卫生风险，这项研究可以为政策制定者和公共卫生倡导者提供有关向儿童进行食品电视广告的潜在有效性以及使用电视媒体运动作为改善这些健康结果的政策工具的重要信息。 公共卫生相关性：拟议的研究将调查用于食品，饮料，餐厅，公共服务饮食和身体活动的电视广告之间的关系，健康饮食和身体活动促进信息，以及使用市场水平电视评级数据以及国家代表性的横向截面和远程人群数据的儿童和青少年的饮食，体育锻炼，体重指数和肥胖。鉴于严重的公共卫生风险，包括饮食不良，不活动性和肥胖带来的癌症和心血管疾病，这项研究可以为政策制定者和公共卫生倡导者提供重要的信息，以提供有关调节对儿童的食品电视广告以及将电视媒体运动作为改善这些健康效果的政策工具的潜在有效性。
