项目摘要/摘要 产后体重滞留(PPWR)，或在产后一年内未能恢复到孕前体重 (PP)，影响大约75%的妇女。PPWR会导致严重的疾病，包括胰岛素抵抗， 高血压、心血管疾病和2型糖尿病。这些风险在25%的女性中被放大了 超重或肥胖的孕妇。此外，与PPWR有关的种族/族裔差异也存在，妇女 肤色越好，越有可能开始怀孕、超重或肥胖，也更有可能经历PPWR。人民党 这一年的特点是独特的挑战和不断变化的社交网络，影响了妇女确定优先事项的能力 健康的饮食和运动。对于有色人种的母亲来说，这些社交网络动态可能会变得复杂 网络的影响和规范可能会特别突出。了解这些动态对于 制定与文化相关的PPWR干预措施。这项提案如果获得资金，将探索 产后社会网络与饮食、活动和产后产后反应的关系：1)数量上 研究饮食、活动量和1年PP时的PPWR如何与结构和功能相关 不同种族/民族的女性样本中的社会网络特征，2)定性 探讨母亲对其社会网络对体重相关健康的影响的看法 行为和PPWR以及3)使用解释性的三角测量定性和定量数据 序贯混合法设计。跨部门、混合方法方法将利用量化 调查和社交网络数据，以创建将用于促进半结构化的网络可视化 对母亲的采访。对定性数据的有针对性的跟踪将与定量数据进行三角测量，以 丰富地了解产后社交网络与饮食、活动和产后产后恢复的关系。 培训计划：授奖期间拟议培训的目标是：1)制定方法 混合方法的道德行为和社会网络分析方面的分析技能；2)高级知识 以及对来自不同种族/民族背景的女性的理解，以及对社会影响的了解 文献；3)开发和实施安全高效的数据库、在线调查和社交网络访谈 协议；以及4)获得为博士后职位做准备的专业发展经验 将获得R1终身教职，并有助于作为一名独立科学家的成长。 环境：犹他大学护理学院有一个强大的博士项目，以 他们对美国国立卫生研究院的资助，以及对妇女健康和照料的研究。此外，该大学还提供了许多 为培训、专业发展和研究提供跨学科协作的机会，包括 妇产科研究网络。

PROJECT SUMMARY/ABSTRACT Postpartum weight retention (PPWR), or the failure to return to pre-pregnancy weight by 1-year postpartum (PP), impacts approximately 75% of women. PPWR can lead to serious morbidity including insulin resistance, hypertension, cardiovascular disease, and type 2 diabetes. These risks are magnified among the 25% of women who enter pregnancy overweight or obese. Moreover, racial/ethnic disparities exist related to PPWR, with women of color being more likely to begin pregnancy overweight or obese and more likely to experience PPWR. The PP year is characterized by unique challenges and changing social networks, impacting women’s ability to prioritize healthy diet and activity. These social network dynamics may be compounded for mothers of color for whom network influence and norms can be particularly salient. Understanding these dynamics is essential for the development of culturally-relevant PPWR interventions. This proposal, if funded, will explore the associations between postpartum social networks and diet, activity, and PPWR by 1) Quantitatively investigating how diet, activity, and PPWR at 1-year PP are associated with structural and functional features of social networks among a sample of racially/ethnically diverse women, 2) Qualitatively exploring mothers’ perceptions about the influence of their social networks on weight-related health behaviors and PPWR and 3) Triangulating qualitative and quantitative data using an explanatory sequential mixed methods design. A cross-sectional, mixed-methods approach will leverage quantitative survey and social-network data to create network visualizations that will be used to facilitate semi-structured interviews with mothers. Targeted follow-up of qualitative data will be triangulated with quantitative data to provide a rich understanding of how postpartum social networks are associated with diet, activity and PPWR. Training Plan: The aims of the proposed training during the award period are: 1) Develop methodological and analytical skills in the ethical conduct of mixed methods and social network analysis; 2) Advance knowledge and understanding of women from racially/ethnically diverse backgrounds, and about the social influence literature; 3) Develop and implement a secure and efficient database, online survey, and social-network interview protocol; and 4) Acquire experience in professional development preparatory to a post-doctoral position which will lead to an R1 tenure-track faculty position and contribute to growth as an independent scientist. Environment: The College of Nursing at the University of Utah has a strong PhD program, well known for their NIH funding and women’s health and caregiving research. Further, the University provides numerous opportunities for interdisciplinary collaboration for training, professional development, and research, including the Obstetrics and Gynecology Research Network.
