Joining Forces with a Key Community to Combat Obesity Disparities-2

这项建议旨在测试一种多层次的干预措施，旨在通过纳入 体育活动（PA）和更健康的食物选择纳入工作场所的日常工作，根据初步结果， ：三年期国家民政管理委员会资助的规划赠款。相关性：以人口为基础的肥胖控制目标 环境变化以及个人生活方式的变化是研究不足，特别是在服务不足， 社区.然而，肥胖越来越被认为是慢性病差异的主要因素。 这项建议的目标工作人员，主要是有色人种的妇女，谁的工作人员机构，解决低收入的需要， 和少数民族人口。这些工人是其家庭和社区的守门人。 使他们成为志愿者可能有助于创造社会规范的变化和打击肥胖所需的政治意愿 疫情将健身推广活动和产品融入到常规的"商业"行为中， 一个有前途的干预方法，从我们的3年社区为基础的前瞻性研究（CBPR） 规划过程。我们寻求通过使用由此产生的干预战略来实现这些目标。 规划阶段，例如：举行步行会议;在工作人员中实施短暂的锻炼休息 会议;在工作中增加水果、蔬菜和水作为茶点;推广/改善楼梯间等。 具体而言，我们将： 1..招募洛杉矶南部和东部的健康和社会服务组织，以确定60个工作 每个单位10 - 50名工作人员（平均=每个工作单位25人）。工作单位可以是整个组织，也可以是共同组织。 在较大的组织中定位组（工作站点）。 2.采用双臂、分组随机、等候列表对照研究设计，以工作场所为单位， 分析，以严格评估这种干预方法。主要的结局指标是腰围 周长（WC）。次要结果指标是体重指数（BMI）、心肺功能 血压（BP）。中介变量包括自我报告的PA和营养素摄入量，7天 加速度计计数和强度读数，PA审计，感知身体活动和营养规范，以及 组织的做法/政策。将在基线以及6、12和18个月随访时收集数据。 3.分析过程和结果数据;利用结果制定传播计划。 主要假设是实验组的平均WC在12个月时不会增加 与对照组的显著增加相比。第二个假设是， 与对照组相比，参与者将经历BMI稳定和BP和健身的改善， 12个月预计18个月时会出现类似结果。

This proposal seeks to test a multi-level intervention designed to influence the work culture by incorporating physical activity (PA) and healthier food choices into the workplace routine, based on preliminary results of a :hree-year NCMHD-funded planning grant. Relevance: Population-based obesity control targeting environmental change as well as individual lifestyle change is understudied, particularly in underserved communities. Yet, obesity is increasingly recognized as a major contributor to chronic disease disparities. This proposal targets staff, mostly women of color, who staff agencies that address the needs of low-income and ethnic minority populations. These workers are gatekeepers for their families and communities. Vlobilizing them may help to create the social norm change and political will needed to combat the obesity epidemic. Integrating fitness promoting activities and products into the regular conduct of "business" is a promising intervention approach arising from our 3-year Community Based Participatory Research (CBPR) planning process. We seek to achieve these goals by using the intervention strategies emerging from this planning phase, such as: conducting walking meetings; implementing brief exercise breaks in staff meetings; adding fruits, vegetables and water as refreshments at work; promoting /improving stairwells,etc. Specifically, we will: 1.. Recruit health and social services organizations in southern and eastern Los Angeles to identify 60 work units of 10-50 staff members each (mean=25 per work unit). Work units may be entire organizations or co- located groups (worksites) within larger organizations. 2. Employ a two-armed, group-randomized, wait list-controlled study design with the work site as the unit of analysis to rigorously evaluate this intervention approach. The primary outcome measure is waist circumference (WC). Secondary outcome measures are body mass index (BMI), cardiorespiratory fitness and blood pressure (BP). Mediating variables include self-reported PA and nutrient intake, 7-day accelerometer count and intensity readings, PA audits, perceived physical activity and nutrition norms, and organizational practices/policies. Data will be collected at baseline, and 6, 12, and 18 months follow-up. 3. Analyze process and outcome data; use results to develop a dissemination plan. The primary hypothesis is that mean WCs in the experimental group will not increase at 12 months compared with significant increases in the control group. The secondary hypothesis is that intervention participants will experience BMI stabilization and improvements in BP and fitness, compared with controls, at 12 months. Similar outcomes are expected at 18 months.
