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。该指导研究科学家发展奖（K 01）的目标是学习评估体力活动和胰岛素作用所需的技能，并学习社区家庭干预和公共卫生的理论和方法。像非洲裔美国妇女一样，非洲裔美国女孩不成比例地患有肥胖症。肥胖患病率的增加与儿童2型糖尿病（T2 DM）的发病率增加相关。与儿童肥胖和T2 DM患病率增加相关的一个因素是他们的体力活动水平降低。减少体力活动在非洲裔美国女孩和妇女中更为普遍，因此需要有效的体力活动干预。对于身体活动干预是有效的非洲裔美国女孩的程序必须与他们产生共鸣，他们必须享受参与其中。一个可能的例子是一个愉快的，文化上适当的干预是非洲为中心的舞蹈。此外，有人推测，提高儿童身体活动水平的一种方法是提高父母的身体活动水平。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，还没有研究探讨女儿-母亲体育活动计划对非洲裔美国女孩活动水平的影响。我们建议研究的可行性和有效性的12周的随机对照干预，从事非洲裔美国人的女儿和母亲在非洲为中心的舞蹈。主要结局变量是每日总体力活动（加速度计计数/分钟）和中度至剧烈体力活动所花费的时间。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，通过选择一种文化上合适的、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：如果这种干预为非洲裔美国女孩及其母亲增加身体活动提供了一种可行的选择，我们将确定一种减少这些群体中肥胖和T2 DM的途径。 公共卫生相关性：非裔美国女孩患肥胖症和糖尿病等相关健康问题的比例过高，部分原因是身体活动水平低。我们将研究一个文化适当的舞蹈干预，从事母亲，谁是非洲裔美国女孩的关键行为榜样的有效性。我们希望这种方法为母亲和女儿提供一种持续体力活动的可行途径，从而减少肥胖和糖尿病。

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. PUBLIC HEALTH RELEVANCE: African-American girls suffer disproportionately from obesity and related health problems such as diabetes, in part from low levels of physical activity. We will study the effectiveness of a culturally-appropriate dance intervention that engages the mother, who is the key behavioral role model for African-American girls. We hope this approach presents a viable route to sustained physical activity for both mothers and daughters, thereby reducing obesity and diabetes.
