Mothers and Girls DaNcing togETher Trial (Magnet Trial)

描述（由申请人提供）：Alhassan博士的主要研究兴趣是体育活动对少数民族儿童和青少年肥胖和相关并发症的影响。这项指导研究科学家发展奖（K01）的目标是学习评估身体活动和胰岛素作用所需的技能，并学习以社区家庭为基础的干预措施和公共卫生的理论和方法。和非裔美国女性一样，非裔美国女孩也不成比例地肥胖。肥胖患病率的增加与儿童2型糖尿病（T2DM）发病率的增加有关。与儿童肥胖和2型糖尿病患病率增加相关的一个因素是他们的体育活动水平下降。体育活动减少在非裔美国女孩和妇女中更为普遍；因此，需要有效的身体活动干预。要使体育活动干预对非洲裔美国女孩有效，该项目必须引起她们的共鸣，她们必须喜欢参与其中。以非洲为中心的舞蹈可能是一种令人愉快的、文化上适当的干预。此外，有人推测，增加儿童体育活动水平的一种方法是增加父母的体育活动水平。研究表明，父母（母亲）的健康行为会影响儿童的健康行为。家庭仍然是非洲裔美国人文化的一个重要方面，因此是干预改善身体活动和其他健康结果的重要行为背景。目前，还没有研究检查女儿-母亲体育活动计划对非裔美国女孩活动水平的影响。我们建议研究一项为期12周的随机对照干预的可行性和有效性，该干预涉及非裔美国人的女儿和母亲参与以非洲为中心的舞蹈。主要结果变量是每日总体力活动（加速度计计数/分钟）和花在中度到剧烈体力活动上的时间。次要结局变量包括体重指数、空腹胰岛素水平和社会心理因素。我们假设，通过选择一种文化上合适且有趣的体育活动形式，并让母亲参与进来，我们将看到更高水平的持续体育活动。因此，我们应该看到相关生物标志物的改善。影响：如果这种干预为增加非裔美国女孩及其母亲的身体活动提供了一个可行的选择，我们将确定减少这些群体肥胖和2型糖尿病的途径。

DESCRIPTION (provided by applicant): Dr. Alhassan's primary research interest is in the effects of physical activity on obesity and related co- morbidities in ethnic minority children and adolescents. Goals for this Mentored Research Scientist Development Award (K01) are to learn the skills necessary for assessing physical activity and insulin action, and to learn theory and methodology for community family-based interventions and public health. Like African-American women, African-American girls suffer disproportionately from obesity. The increased prevalence of obesity has been associated with an increased incidence of pediatric Type 2 diabetes mellitus (T2DM). A factor associated with the increased prevalence of obesity and T2DM in children is a decrease in their physical activity levels. Reductions in physical activity are more prevalent in African-American girls and women; therefore effective physical activity interventions are needed. For a physical activity intervention to be effective among African-American girls the program must resonate with them and they must enjoy participating in it. One possible example of an enjoyable, culturally-appropriate intervention is Afro-centric dance. In addition, it has been speculated that a way to increase children's physical activity level is to increase parental physical activity level. Studies have shown that parental (maternal) health behaviors can influence children's health behaviors. Family remains a valued facet of the African-American culture, and therefore an important behavioral context for interventions to improve physical activity and other health outcomes. Currently, there are no studies examining the effects of a daughter-mother physical activity program on the activity levels of African-American girls. We propose to examine the feasibility and efficacy of a 12-week randomized control intervention that engages African-American daughters and mothers in Afro-centric dance. The primary outcome variable is total daily physical activity (accelerometer counts/minute) and the amount of time spent in moderate to vigorous physical activity. The secondary outcome variables include body mass index, fasting insulin levels, and psychosocial factors. We hypothesize that by choosing a culturally-appropriate and fun form of physical activity, and by engaging mothers, we will see higher levels of sustained physical activity. As a result, we should see improvements in related biomarkers. IMPACT: If this intervention presents a viable option for increasing physical activity for African-American girls and their mothers, we will have identified a route for reducing obesity and T2DM in these groups.
