DIET/ACTIVITY OF MEXICAN AMERICAN AND ANGLO CHILDREN

墨西哥裔美国人的纵向研究群体很少。 英美儿童和他们的父母同时 调查心血管、行为和生理风险因素 从学龄前到青春期早期。对中国的大部分研究 儿童饮食和体力活动的决定因素是 横截面。目前的研究人群，在队列中仍然很强大 留存率(7年后接近68%)将通过 未来3年的青春期。这提供了一个独特的机会 扩展和合并已在4-7岁之间收集的丰富数据，以及 同样在10-11岁，到[14-16]岁。本研究 将延续先前对风险因素、健康状况评估的优势 行为和行为决定因素，但增加了与青少年相关的 吸烟行为的测量，与抑郁相关的感觉，以及 同龄人的影响；变化的父母的影响也被评估。这 学习期间还将集中讨论文化适应对 墨西哥裔美国人的这些健康行为。这 纵向研究将为寻求 因子实验操作的科学基础 针对特定性别、种族和年龄的青年的干预试验 特点。研究的具体目标是前瞻性的和 就这些目标中的许多目标而言，性别和种族可以 被评估为协会的调解人。 在这项针对来自两个民族的年轻人及其母亲的研究中， 前瞻性分析的目的是：1.研究决定因素 体力活动和膳食中总脂肪、饱和脂肪、 钠和能量，以及这些行为在4岁到 [14-16岁]。2.确定饮食和饮食之间的关系 体力活动习惯和危险的生理指标，例如 血压、肥胖、体重指数和血清脂蛋白 年龄从4岁到[14-16]岁。3.描述物理的跟踪程度 运动习惯和饮食中脂肪、钠和能量的摄入量 [14-16岁]。4.研究文化适应的变化对 墨西哥裔美国人父母和父母的饮食和体育活动行为 从4岁到[14-16]岁的儿童。横断面分析的目的 目标：1.确定 身体健康、肥胖和吸烟与心血管疾病的关系 [14~16]岁儿童的生理和行为危险因素 墨西哥裔美国人和英裔美国人青年。2.审视两国关系 抑郁与饮食、体育锻炼对心血管危险行为的影响 墨西哥裔美国人和英裔美国人的活动和健身以及吸烟 [14-16岁]。

There are very few longitudinal study populations of Mexican-American and Anglo-American children and their parents which simultaneously investigate cardiovascular, behavioral and physiologic risk factors from preschool through early adolescence. Most of the studies of the determinants of diet and physical activity in children are cross-sectional. The current study population, still robust in cohort retention (nearly 68 percent after 7 years) will pass through adolescence in the next 3 years. This provides a unique opportunity to extend and combine the rich data already collected between ages 4-7, and again at ages 10-11, to the age period of [14-16] years. This study will continue the strengths of prior assessments of risk factors, health behaviors and behavioral determinants, but add adolescent-relevant measures of smoking behavior, feelings associated with depression, and peer influences; changing parental influences are also assessed. This study period will also concentrate on the influence of acculturation on these health behaviors in the Mexican-American population. This longitudinal study will add important data for investigators seeking a scientific basis for experimental manipulation of factors in intervention trials with youth of specific gender, ethnic and age characteristics. The specific aims of the study are prospective and cross-sectional, and for many of these aims, gender and ethnicity can be assessed as mediators of associations. In this study of young people and their mothers from two ethnic groups, aims of prospective analyses are to: 1. Study the determinants of physical activity and dietary intake of total fat, saturated fat, sodium, and energy, and changes in these behaviors in 4 year olds to [14-16] year olds. 2. Determine the relationships between diet and physical activity practices and physiologic indicators of risk, such as blood pressure, adiposity, body mass index, and serum lipoproteins at ages 4 to [14-16]years. 3. Describe the degree of tracking of physical activity habits and dietary intake of fat, sodium, and energy in 4 to [14-16] year olds. 4. Study the impact of changing acculturation on dietary and physical activity behaviors in Mexican-American parents and children from ages 4 to [14-16] years. Aims of cross-sectional analyses are to: 1. Determine the associations among physical fitness, adiposity, and smoking to CVD physiologic and behavioral risk factors in [14-16] year old Mexican-American and Anglo-American youth. 2. Examine the relationship of depression to cardiovascular risk behaviors of diet, physical activity and fitness, and smoking in Mexican-American and Anglo-American [14-16] year olds.
