The NICHD Study proposes to extend the data collection on approximately 1000 children, ages 8-11, thereby offering an opportunity to expand the study to examine the impact of environmental determinants on selected aspects of middle childhood development. This proposal adds a dimension of a health behavior (physical activity) to the battery of social, emotional, cognitive, linguistic, and health development variables studied over their first seven years of life. Studies of the relationships between psychosocial and educational development, and the development of a health-related behavior are rare if not nonexistent in the literature. The NICHD Study of Early Child Care, when extended to the middle school years, provides an opportunity to simultaneously study the environmental and contextual influences on psychosocial and academic development as well as the determinants of physical activity behaviors. The specific aims of the research are: 1) to determine the antecedents of physical activity in a longitudinal sample of 8- to 11-year-old children; and, 2) to assess relationships between physical activity and other measures of psychosocial, cognitive, and academic development. A proposed measure, BEACHES (Behaviors of Eating and Activity for Children's Health Evaluation System) has been validated as an observation tool. It can be used, within a theoretical framework (social cognitive theory), to examine home and school determinants of physical activity. The detailed analysis of the contextual environment, interactions (prompts and consequences), as well as the interactors' age, gender, ethnicity, and relationships will provide data not available in this age group. The instrument could also be modified to observe behaviors and interactions relevant to a final protocol decided upon by the NICHD Study of Early Child Care Investigators. The results may yield important associations with other key developmental tracking areas related to emotional and physical health. The study is unique because psychosocial and health behavior developmental strands have not previously been woven together in any prospective study of development.

NICHD研究建议扩大对大约1000名8-11岁儿童的数据收集，从而提供一个机会，扩大研究范围，以审查环境决定因素对儿童中期发展某些方面的影响。 这项建议增加了一个维度的健康行为（体力活动）的电池的社会，情感，认知，语言和健康发展的变量研究在他们的前七年的生活。 心理社会和教育发展之间的关系，以及健康相关行为的发展的研究是罕见的，如果不是在文献中不存在。 NICHD的幼儿保育研究，当扩展到中学几年，提供了一个机会，同时研究环境和上下文对心理社会和学术发展的影响，以及身体活动行为的决定因素。 研究的具体目的是：1）确定8至11岁儿童纵向样本中身体活动的前因; 2）评估身体活动与其他社会心理，认知和学术发展措施之间的关系。一项拟议的措施，海滩（儿童健康评价系统的饮食和活动的行为）已被验证为一个观察工具。 它可以用来，在一个理论框架（社会认知理论），检查家庭和学校的身体活动的决定因素。 对情境环境、互动（提示和后果）以及互动者的年龄、性别、种族和关系的详细分析将提供该年龄组中不可用的数据。该仪器也可以修改，以观察行为和相互作用有关的最终协议决定由NICHD研究的早期儿童保育调查员。这些结果可能与其他与情绪和身体健康相关的关键发展跟踪领域产生重要关联。 这项研究是独一无二的，因为心理社会和健康行为发展链以前没有被编织在一起，在任何前瞻性的发展研究。
