A Community Partnership to Reduce Blood Pressure among African American Adults

长期目标是利用基于社区的参与性研究(C6PR)方法来实现 增强社区能力，促进体育活动和健康食品选择，并制定 基于社区的流程和模型方案，实现持续降低收缩压血 密西西比州哈蒂斯堡非裔美国成年人的压力(SBP)。这种干预的动机是 密西西比州高血压、肥胖症、缺乏体力活动和心血管疾病的比率 非裔美国人是全国最高的之一，社区希望解决这一问题 通过协作的社区方法解决问题。具体目标是：1)开发和评估 社区能力，以促进体育活动和健康食物选择，2)测试治疗效果 6个月的CBPR步行干预对所有步行参与者的收缩压的影响，以及3)测试 电话持续激励强化对SBP的治疗效果。能力建设是 通过多项战略解决，以在干预期间加强以下具体方面 能力，包括参与、领导力、技能、资源、网络、批判性反思和社区 权力。全面的进程评估将捕捉到社区能力增强的证据 通过多种跟踪方法以及来自所有参与者级别的定性反馈。干预措施 阶段包括为期6个月的CBPR步行干预，以降低收缩压，使用单一 小组岗前设计，包括以下组成部分：志愿者步行提供的社会支持 组长，训练有素的干预人员的激励性访谈(ML)，计步器日记自我监控， 和每月的教育课程。参与者将在6个月后随机进入为期12个月的Mi- 增强或非增强维护组，其中Mi-Enhance接受4毫升电话咨询 课时，以鼓励持续的体力活动。结果衡量标准将在3至12岁时进行评估 在干预和维护阶段每隔一个月。个人、群体和干预水平 流程措施将每周至每季度进行一次评估。一个成功的干预将会有一个 可持续的基础设施，以继续解决健康差距并显示出血液减少 对降低心血管疾病发病率和死亡率具有公共卫生影响的压力。

Long term objectives are to utilize a community-based participatory research (C6PR) approachto achieve enhanced communitycapacity to promote physical activity and healthy food choices and to develop a community-based process and model protocol that achieves a sustained reduction in systolic blood pressure (SBP) amongAfrican American adults in Hattiesburg, Mississippi. This intervention is motivated by rates of hypertension, obesity, lack of physical activity, and cardiovascular disease among Mississippi African Americans that are amongthe highest in the nation, and by the community's desire to address this problem through collaborative community approaches. Specific aims are: 1) to develop and assess community capacity to promote physical activity and healthy food choices, 2) to test treatment effects of a 6-month CBPR walking intervention on systolic blood pressure among all walking participants, and 3) to test the treatment effects of a sustained motivational enhancement via telephone on SBP. Capacity building is addressed through multiple strategies to enhance, over the life of the intervention, specific dimensions of capacity including participation, leadership, skills, resources, networks, critical reflection, and community power. A comprehensive process evaluation will capture evidence of enhanced community capacity through multiple tracking methods aswell as qualitative feedback from all participant levels. The Intervention Phase consists of a 6-month CBPR walking intervention to lower systolic blood pressure, using a single group pre-post design and including the following components: social support provided by volunteer walking group leaders, motivational interviewing (Ml) by trained intervention staff, pedometer diary self-monitoring, and monthly education sessions. Participants will be randomized at six months into a 12-month Mi- enhanced or non-enhanced maintenance group, with Mi-enhanced receiving four Ml telephone counseling sessions to encourage continued physical activity. Outcome measures will be evaluated at three- to 12- month intervals throughout intervention and maintenance phases. Individual, group and intervention level process measures will be evaluated at weekly to quarterly intervals. A successful intervention will have a sustainable infrastructure to continue addressing health disparities and demonstrate a reduction in blood pressure with public health implications for reducing cardiovascular disease morbidity and mortality.
