Project Summary/Abstract Black female adolescents are at increased risk for obesity-related morbidity and mortality as adults compared to non-Hispanic White female adolescents. Interventions to prevent obesity in Black female adolescents that leverage the relationship of the daughter/mother dyad have received limited attention. Studies that do include mothers tend to use theoretical frameworks that do not explicitly build on this important family relationship and have not included mothers’ active participation. Additionally, these studies do not include girls over the age of 12. In response, we developed Black Girls Move, a school-based obesity prevention intervention that addresses these limitations in the extant literature. We conducted focus groups with daughter/mother dyads to identify practical, cultural, and age-appropriate strategies for improving physical activity (PA) and dietary behaviors in Black adolescent daughters (grades 9-10, ages 14-17). Black Girls Move consists of 12 weekly group sessions of daughter/mother dyads in which participants set individualized PA and dietary goals. Black Girls Move incorporates content and processes derived from asset-based anti-racist Public Health Critical Race Praxis, Family Systems Theory, and Social Cognitive Theory. Specific aims are to determine the efficacy of Black Girls Move compared to daughters-only comparison condition on change in PA and dietary intake, and the impact of Black Girls Move compared to daughters-only on theoretical mechanisms of change (racial identity, daughter/mother relationship, social cognitions) assessed by self-report measures. The design is a 12-week pre-test/post-test, randomized controlled trial. We will recruit 24 daughter/mother dyads at each of 8 schools for a total sample size of 192 daughter/mother dyads. Within school, each dyad will be randomized to either Black Girls Move or daughters-only comparison condition (12 per condition). All daughters and all mothers (Black Girls Move daughter/mother dyads and daughters-only comparison condition daughter/mother dyads) complete assessments (e.g., PA, diet, family measures) at baseline, post-intervention, and 3-months post-intervention. We recognize that there are potential validity threats associated with within- school student randomization. We will collect data to assess the degree to which these potential threats are pertinent. The long-term goal of this research is to decrease disparities in obesity and associated co- morbidities in Black women. The findings may inform future large scale R01 studies of BGM in Black daughter/mother dyads.

项目总结/摘要 黑人女性青少年成年后患肥胖相关疾病和死亡的风险高于 非西班牙裔白色女性青少年。预防黑人女性青少年肥胖的干预措施， 利用女儿/母亲二元体的关系受到了有限的关注。这些研究包括 母亲们倾向于使用理论框架，而这些理论框架并没有明确地建立在这种重要的家庭关系之上， 没有包括母亲的积极参与。此外，这些研究不包括年龄超过 12.作为回应，我们开发了Black Girls Move，这是一项基于学校的肥胖预防干预措施， 解决了现存文献中的这些局限性。我们与女儿/母亲二人组进行了焦点小组讨论， 确定实用的，文化的，适合年龄的策略，以改善体力活动（PA）和饮食 黑人青春期女儿（9-10年级，14-17岁）的行为。黑人女孩运动包括12个每周 小组会议的女儿/母亲二人组，参与者设置个性化的PA和饮食目标。黑色 Girls Move整合了基于资产的反种族主义活动的内容和流程 种族实践，家庭系统理论和社会认知理论。具体目标是确定 黑人女孩移动与仅女儿比较条件对PA和饮食变化的功效 摄入量，以及黑人女孩移动的影响相比，只有女儿的理论机制的变化 （种族认同，女儿/母亲的关系，社会认知）通过自我报告的措施进行评估。 设计为12周的前测/后测随机对照试验。我们将招募24名女儿/母亲 在8所学校的每一对，总样本量为192个女儿/母亲对。在学校里，每一个二元组都将 被随机分配到黑人女孩移动或女儿只有比较条件（每种条件12）。所有 女儿和所有的母亲（黑人女孩移动女儿/母亲二人组和女儿只比较条件 女儿/母亲二联体）完成评估（例如，PA、饮食、家庭测量）， 以及干预后3个月。我们认识到存在与内部相关的潜在有效性威胁- 学校学生随机分组。我们将收集数据，以评估这些潜在威胁的程度。 中肯这项研究的长期目标是减少肥胖和相关疾病的差异， 黑人女性的病态这些发现可能会为未来大规模的R 01研究提供信息 女儿/母亲二人组。
