Implementing a Physical Activity Program in Hawaiian Elementary Schools

描述（由申请人提供）：肥胖，与包括癌症在内的几个健康问题密切相关，在美国已达到流行病的水平。肥胖的儿童和青少年更容易肥胖到成年，而成年人的肥胖很难治疗。对儿童的干预应该有助于预防成年人的肥胖，但很少有学校有时间提供定期的体育教育。学校是否可以纳入15-20分钟的运动计划，以最大限度地提高摄氧量（最大摄氧量），这是否可以帮助儿童达到健康的体重？这项研究建议：1）进行初步的现场有效性测试一个15-20分钟的体育活动计划2）确定将其纳入小学教室日常活动的可行性奥廷加的卡胡库小学综合体的两所学校同意参与这项研究，其中一半的孩子是夏威夷土著人或其他太平洋岛民。每所学校招收1-6年级约500名学生。在每所学校，从一年级到六年级的每个年级的教室将被随机分成治疗教室和对照教室。治疗教室将接受干预-每周4天15-20分钟的体育活动计划，由当地大学体育专业的大四学生领导。控制教室将遵循他们的常规。两所学校都将获得酬金，对照教室将在研究完成后获得干预材料和培训。测试前和测试后的措施将采取BMI，臀部和腰围，皮肤褶皱，并直接身体成分使用BOD POD的学生在治疗和控制教室。将保留学生参加治疗教室的每日记录，以确定他们的参与情况。可行性调查问卷将由学生、任课教师、校长和学区官员在学年中期和年底填写。这些数据将为将来在更大的学校样本中进行干预的随机对照试验提供信息。

DESCRIPTION (provided by applicant): Obesity, closely linked to several health problems, including cancer, has reached epidemic levels in the U.S. The highest rates are seen in minority populations, including Native Hawaiians and other Pacific Islanders. Obese children and adolescents are more likely to be obese into adulthood, and obesity in adults is difficult to treat. Interventions in childhood should help prevent adult obesity, but few schools have time to provide regular physical education. Can schools incorporate a 15-20-minute exercise program that maximizes oxygen intake capacity (VO2 max), and can this help children achieve healthy body weights? This study proposes to: 1) conduct a preliminary field test of effectiveness a 15-20-minute physical activity program 2) determine the feasibility of inserting it into the daily routine of elementary school classrooms Two schools in the Kahuku Elementary School complex on O'ahu, in which half of children are Native Hawaiian or other Pacific Islander, have agreed to be involved in the study. Each school enroll enrolls about 500 students in grades 1-6. In each school, classrooms at each grade level-1st through 6th-will be randomized into treatment and control classrooms. Treatment classrooms will receive the intervention-the 15-20-minute physical activity program 4 days a week, led by college seniors majoring in physical education at a local university. Control classrooms will follow their usual routine. Both schools will receive an honorarium, and control classrooms will receive intervention materials and training after the study is completed. Pre- and post-test measures will be taken of BMI, hip and waist circumferences, skin folds, and direct body composition using the BOD POD of students in treatment and control classrooms. Daily records of participation by students in treatment classrooms will be kept to ascertain their engagement. Feasibility questionnaires will be completed by students, classroom teachers, principals, and school district officials in the middle and at the end of school year. These data will inform a future randomized control trial of the intervention in a much larger sample of schools.
