CONDUCT FOCUS GROUPS AND INTERVIEWS TO INFORM NEXT SURVEY DEVELOPMENT

预防研究处(PRB)是尤尼斯·肯尼迪·施莱弗国家儿童健康和人类发展研究所(NICHD)的一个内部研究小组，正在进行学龄儿童健康行为研究的纵向组成部分。这项纵向研究被称为NEXT。下一项研究收集有关青少年健康状况和健康行为的信息。根据HBSC的纵向研究，招募了一个由大约2800名美国10年级学生组成的全国代表性队列。对非洲裔美国青年进行了过度抽样，以提供更好的人口估计，并提供足够的样本来检验种族/民族在健康、健康行为和健康行为变化的纵向预测因素中的差异。健康状况、健康行为和健康态度的自我报告是通过在校和在线调查收集的。还收集了所有下一位参与者的人体测量和邻里数据。 一个名为Next Plus的子样本包括从下一个队列招募的大约275名正常体重和275名超重或肥胖参与者。对Next Plus子样本进行的其他评估包括：对体力活动、久坐行为和睡眠的客观评估；生物和遗传标记，包括肥胖、心血管疾病和代谢综合征的标记。此外，我们将跟踪空腹血糖、糖化血红蛋白、总胆固醇、甘油三酯、低密度脂蛋白、高密度脂蛋白、C反应蛋白、尿酸、可替宁、身高、体重、腰围？使用汽车仪表对Next Plus参与者的驾驶表现进行最多四项额外评估；

The Prevention Research Branch (PRB), an intramural research group of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) is conducting a longitudinal component of the ¿Health Behavior in School-Ages Children (HBSC)¿ study. This longitudinal study is called ¿NEXT¿. The NEXT study collects information on adolescent health status and health behaviors. A nationally-representative cohort of approximately 2,800 U.S. 10TH grade students was recruited academic years under the HBSC longitudinal study. African-American youth were oversampled to provide better population estimates and to provide an adequate sample to examine racial/ethnic differences in longitudinal predictors of health, health behaviors, and health behavior change. Self-report of health status, health behaviors, and health attitudes are collected by in-school and online surveys. Anthropometric and neighborhood data are also collected for all NEXT participants. A subsample called ¿NEXT Plus¿ includes approximately 275 normal weight and 275 overweight or obese participants who were recruited from the NEXT cohort. The additional assessments performed with the NEXT Plus subsample include: objective assessment of physical activity, sedentary behavior, and sleep; biological and genetic markers including those for obesity, cardiovascular disease, and metabolic syndromes. In addition, we will be tracking fasting blood glucose, HbA1c, total cholesterol, triglycerides, LDL-C, HDL, C-reactive protein, uric acid, cotinine, height, weight, waist ¿ Up to four additional assessments of driving performance of NEXT Plus participants using instrumentation of their cars;
