Mothers and Girls DaNcing togETher Trial (Magnet Trial)

简介(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共病的影响。指导研究科学家发展奖(K01)的目标是学习评估体力活动和胰岛素作用所需的技能，并学习社区基于家庭的干预和公共卫生的理论和方法。与非裔美国女性一样，非裔美国女孩也不成比例地患有肥胖症。肥胖患病率的增加与儿科2型糖尿病(T2 DM)发病率的增加有关。儿童肥胖症和2型糖尿病患病率增加的一个相关因素是他们的体力活动水平下降。减少体力活动在非裔美国女孩和妇女中更为普遍；因此，需要进行有效的体力活动干预。为了让体育活动干预在非裔美国女孩中有效，该计划必须引起她们的共鸣，她们必须喜欢参与其中。一个可能的例子是以非洲为中心的舞蹈，这是一种令人愉快的、适合文化的干预。此外，据推测，增加儿童体力活动水平的一种方法是增加父母的体力活动水平。研究表明，父母(母亲)的健康行为会影响儿童的健康行为。家庭仍然是非裔美国人文化的一个重要方面，因此是改善身体活动和其他健康结果的干预措施的重要行为背景。目前，还没有研究考察女儿-母亲体育活动计划对非裔美国女孩活动水平的影响。我们建议检验为期12周的随机对照干预的可行性和有效性，该干预让非裔美国人的女儿和母亲参与非洲中心舞蹈。主要的结果变量是每天的总体力活动(加速计计数/分钟)和在中等到剧烈的体力活动中花费的时间。次要结果变量包括体重指数、空腹胰岛素水平和心理社会因素。我们假设，通过选择一种适合文化和有趣的体育活动形式，并通过让母亲参与，我们将看到更高水平的持续体育活动。因此，我们应该会看到相关生物标志物的改善。影响：如果这项干预为增加非裔美国女孩及其母亲的体力活动提供了一个可行的选择，我们将确定一条减少这些群体中肥胖和T2 DM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.
