It is well documented that the roots of cardiovascular diseases (CVD) ar evident in childhood, and elevated levels of serum lipids, blood pressur and body fat are common in childhood. These risk factors are, in turn, related to childhood dietary and physical activity habits. To understan the early development of CVD, it is therefore important to study factors that influence diet and physical activity behaviors in children. Most studies concerned with the determinants of diet and physical activity in children are cross-sectional, limiting their utility for improving understanding of the development of these key health behaviors. The proposed study will allow prospective analyses of the behaviors over a significant portion of the prepubertal age range. Knowledge of the determinants, stability, and relationships of childhood dietary and physical activity behaviors to physiologic risk variables could be usefu for setting priorities and designing public health interventions for the next generations of youth. The revised SCAN project will allow follow-up study of physical activity and dietary behaviors and their determinants in 10- to 11-year-old Anglo and Mexican-American children from low- and middle-socioeconomic status (SES) families who were studied initially when they were 4 to 7 years old. Selection of possible determinants to be studied is based on socia learning/cognitive theory, which states that behaviors are a function of personal and environmental factors. The specific aims of the study are as follows: 1) To study the determinants of physical activity and dietary intake of fat, sodium, and calories, and changes in these behaviors in children from ages 4 to 10-11. 2) To determine the relationships between diet and physical activity practices and physiologic indicators of risk, such as blood pressure, adiposity, body mass, and serum lipoproteins at ages 4 to 10-11. 3) To describe the time trends and the degree of tracking of physical activity habits and nutritional intake of fat, sodium, and calories in children from ages 4 to 10-11. The major contribution of this San Diego SCAN study will be the longitudinal analysis of dietary and physical activity behaviors in children. The follow-up assessment of our now 10-to 11-year-old cohort and their mothers will produce data that will substantially improve understanding of the determinants and tracking of children's dietary and physical activity behaviors, as well as their relations to CVD risk factors.

据文献记载，心血管疾病（CVD）的根源是 在儿童时期明显，血脂水平升高，血压升高， 和身体脂肪在儿童时期很常见。 这些风险因素依次是， 与儿童的饮食和身体活动习惯有关。 理解 心血管疾病的早期发展，因此重要的是要研究因素 影响儿童的饮食和身体活动行为。 最 研究有关的饮食和体力活动的决定因素， 儿童是横截面的，限制了他们的效用， 了解这些关键健康行为的发展。 的 拟议的研究将允许前瞻性分析的行为超过一个 青春期前年龄范围的重要部分。 知识 儿童期饮食的决定因素、稳定性和关系， 身体活动行为与生理风险变量的关系可能是有用的， 制定优先事项和设计公共卫生干预措施， 下一代的年轻人。 修订后的SCAN项目将允许对身体活动进行后续研究 和饮食行为及其决定因素在10至11岁的英国 以及中低社会经济地位的墨西哥裔美国儿童 (SES)在他们4到7岁的时候， 老了 选择可能的决定因素进行研究是基于社会 学习/认知理论，它指出行为是一个功能， 个人和环境因素。 研究的具体目标是 如下所示： 1)研究体力活动和膳食摄入的决定因素， 脂肪、钠和卡路里，以及儿童这些行为的变化 从4岁到10-11岁。 2)确定饮食和体力活动之间的关系 风险的实践和生理指标，如血压， 肥胖、体重和血清脂蛋白。 3)描述物理量的时间趋势和跟踪程度 活动习惯和脂肪、钠和卡路里的营养摄入， 4岁至10-11岁的儿童。 这项圣地亚哥SCAN研究的主要贡献将是 饮食和体力活动行为的纵向分析， 孩子 对我们现在10到11岁的队列的随访评估 他们的母亲将产生数据， 了解儿童饮食和营养的决定因素， 体力活动行为及其与CVD风险的关系 因素
