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）：不良饮食、缺乏运动和肥胖与癌症和心血管疾病等多种慢性疾病的风险增加有关。儿童存在的肥胖和相关健康风险因素可能会持续到成年。拟议的研究将调查食品、饮料、餐馆和公共服务健康饮食和身体活动（HDPA）健康促进信息的电视广告与儿童和青少年的饮食、身体活动、体重指数（BMI）和肥胖之间的关系。美国儿童在电视上看到的绝大多数（97.8%）食品广告营养成分较低，糖、脂肪或钠含量较高。大多数研究评估广告效果的依据是：1）看电视时间与不良饮食和/或肥胖相关的证据；或者，2）小规模自然实验，重点关注食物需求或有限的特定食物选择，这些实验可能具有较低的外部效度。拟议的项目将在很大程度上建立在以前的文献的基础上。具体目标有三个：1）检查食品、饮料和餐厅广告的接触（通过使用年龄和种族特定评级的总产品接触和广告的营养成分来衡量）与儿童和青少年的饮食摄入模式（即，特定食品/类别和外出食物（包括快餐）的消费、饮食质量（即总热量摄入、饮食中的脂肪百分比和糖百分比以及总体健康饮食指数）、体重指数和肥胖； 2）考察HDPA健康促进广告的暴露与饮食、体力活动、BMI和肥胖之间的关系； 3) 检查食品相关和 HDPA 健康促进广告与社区背景因素（即食品价格和餐馆、食品店以及与身体活动相关的商店可用性）以及饮食、活动和 BMI/肥胖之间的相互作用。为了实现这些目标，拟议的研究将使用四种类型数据的独特组合进行二次数据分析：1）购买的所有食品、饮料、餐厅和抗肥胖广告的电视年龄和种族特定收视率数据尼尔森媒体研究针对 106 个指定媒体市场； 2) 有关广告食品的详细营养成分信息， 3) 有关食品价格和出口密度衡量标准的当地背景数据； 4）关于人口膳食摄入量、体力活动以及测量身高和体重的数据来自国家健康和营养检查调查和幼儿纵向研究，这两项具有全国代表性的人口调查，其中一项是纵向调查。拟议的项目代表了迄今为止对食品、饮料、餐厅和 HDPA 健康促进广告与饮食、活动和 BMI 之间关系的最全面的探索。鉴于不良饮食、缺乏运动和肥胖造成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重要信息，了解监管儿童食品电视广告以及利用电视媒体活动作为改善儿童健康的政策工具的潜在有效性。结果。 公共健康相关性：拟议的研究将调查食品、饮料、餐馆和公共服务健康饮食和身体活动健康促进信息的电视广告与使用市场的儿童和青少年的饮食、身体活动、体重指数和肥胖之间的关系级电视收视率数据和具有全国代表性的横截面和纵向人口数据。鉴于不良饮食、缺乏运动和肥胖造成的严重公共卫生风险，包括癌症和心血管疾病，这项研究可以为政策制定者和公共卫生倡导者提供重要信息，了解监管儿童食品电视广告和使用电视媒体宣传作为政策的潜在有效性改善这些健康结果的工具。
