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

这项提议旨在测试旨在通过纳入以下内容来影响工作文化的多层次干预 体力活动(PA)和更健康的食物选择纳入工作场所日常生活，基于一项 ：三年NCMHD资助的规划赠款。相关性：以人群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没有得到充分的研究，特别是在服务不足的地区。 社区。然而，肥胖越来越被认为是慢性疾病差异的主要原因。 这项提案针对的是工作人员，主要是有色人种妇女，他们为满足低收入者需求的机构工作 和少数民族人口。这些工人是他们家庭和社区的守门人。 Vlobil化他们可能有助于创造与肥胖作斗争所需的社会规范变化和政治意愿 流行病。把健身活动和健身产品融入日常的业务活动中是一种 我们为期3年的基于社区的参与性研究(CBPR)提出了一种有前途的干预方法 规划过程。我们寻求通过使用由此产生的干预策略来实现这些目标 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时间 会议；在工作中添加水果、蔬菜和水作为茶点；促进/改善楼梯间等。 具体来说，我们会： 1.。在洛杉矶南部和东部招募健康和社会服务组织，以确定60项工作 每个单位有10-50名工作人员(平均为每个工作单位25人)。工作单位可以是整个组织或联合 位于较大组织内的小组(工作地点)。 2.采用双臂、分组随机、等待名单对照研究设计，以工作现场为单位 分析，以严格评估这一干预方法。主要的结果指标是腰围。 周长(WC)。次要指标为体重指数(BMI)、心肺适合度 和血压(BP)。中介变量包括自我报告的PA和营养摄入量，7天 加速度计计数和强度读数、PA审核、感知的体力活动和营养指标，以及 组织实践/政策。数据将在基线、6个月、12个月和18个月的随访中收集。 3.分析过程和结果数据；使用结果来制定传播计划。 主要的假设是，试验组的平均WCs在12个月时不会增加 与对照组相比有显著增加。第二个假设是干预 与对照组相比，参与者将体验BMI稳定以及血压和体能的改善。 12个月。预计在18个月时也会出现类似的结果。

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.
