Evaluating Microaggressions among Latinx Individuals with Obesity

项目摘要/摘要 尽管拉丁裔人口是美国最大、增长最快的人口之一，但 体验显著的健康差距，特别是在肥胖症方面。造成这种差异的一个可能原因是 在拉丁裔人中，这一群体受到压力生活条件的影响不成比例，包括 歧视，这可能导致与肥胖相关的临床相关性更高的比率(例如，情绪性进食， 身体不活动)。日常层面上与种族地位有关的微妙歧视，称为种族歧视 微侵犯性(MA)在拉丁裔人中很常见，可能是一个被忽视的因素， 与肥胖相关的饮食和缺乏运动行为的显著和独特的差异。这个 这个R21项目的目标是阐明种族MA在肥胖相关饮食中的同时和暂时的作用 和拉丁裔人的身体不活动行为的时间抽样方法(在 28天)。参与者(N=150；50%女性)将是符合肥胖标准的拉丁裔成年人。此外， 目前的提议将决定焦虑敏感度(对躯体感觉的恐惧，如缺乏 呼吸、心跳加速和胸痛)解释了种族MAS与肥胖相关饮食之间的关系 行为(即更情绪化的进食、对食物的渴望、进食时失控和发作 暴饮暴食)和缺乏运动的行为(即，对运动的更大恐惧和感觉到的参与障碍 体育锻炼[PA]和较低的运动自我效能感和中等到剧烈的PA)，并从理论上进行测试 受驱动的风险和复原力因素，包括家庭主义的组成部分(即家庭支助和义务)和 体重污名。目前的提议直接符合#PAR-21-313支持新调查员的目标。 来自全国健康科学领域代表性不足的群体(Brooke Kauffman，Pi是女性 来自弱势背景的新研究人员)进行与科学使命相一致的研究 国家糖尿病、消化和肾脏疾病研究所的区域。知识和经验 从这项建议中获得的信息将被用来指导未来的干预开发和有效性测试 随机临床试验。具体地说，这项研究将增进对前兆的理解和知识，以 在Latinx社区内与肥胖相关的临床相关性，并提供所需的初步数据 成功竞争R01基金以及其他独立研究拨款。

PROJECT SUMMARY/ABSTRACT Despite being one of the largest and fastest-growing demographics in the United States, Latinx persons experience striking health disparities, particularly in terms of obesity. One possible reason for this disparity among Latinx persons is that this population is disproportionately affected by stressful life conditions, including discrimination, which may lead to higher rates of obesity-related clinical correlates (e.g., emotional eating, physical inactivity). Subtle discrimination related to ethnic status at the daily level, known as ethnic microaggressions (MAs), is common among Latinx persons, and may be an underrecognized factor that accounts for significant and unique variance in obesity-related eating and physical inactivity behaviors. The goal of this R21 project is to elucidate the concurrent and temporal role of ethnic MAs in obesity-related eating and physical inactivity behaviors among Latinx persons using time sampling methodology (over the course of 28 days). Participants (N = 150; 50% female) will be Latinx adults meeting criteria for obesity. Furthermore, the present proposal will determine whether anxiety sensitivity (fear of somatic sensations such as shortness of breath, racing heart, and chest pain) accounts for the relation between ethnic MAs and obesity-related eating behaviors (i.e., greater emotional eating, food cravings, loss of control while eating, and episodes of overeating) and physical inactivity behaviors (i.e., greater fears of exercise and perceived barriers to engage in physical activity [PA] and lower exercise self-efficacy and moderate-to-vigorous PA), and test theoretically driven risk and resilience factors, including components of familismo (i.e., familial support and obligations) and weight stigma. The current proposal directly aligns with the goals of # PAR-21-313 to support new investigators from groups nationally underrepresented within the field of health sciences (Brooke Kauffman, PI, is a female new investigator from a disadvantaged background) conducting research aligned with the scientific mission areas of the National Institute of Diabetes and Digestive and Kidney Diseases. The knowledge and experience gained from this proposal will be leveraged to guide intervention development and efficacy testing for future randomized clinical trials. Specifically, this study will enhance understanding and knowledge of precursors to obesity-related clinical correlates within the Latinx community and provide preliminary data needed to successfully compete for R01 funding as well as other independent research grants.
