JOHN HENRYISM & HYPERTENSION-RISK IN BLACKS

这项拟议的研究将调查心理社会和饮食 人群概率样本对血压的影响 居住在皮特县的25-50岁的黑人男女， 北卡罗来纳州。最令人感兴趣的心理社会变量 包括社会经济地位、约翰·亨利主义、社会支持 和应对愤怒的方式。最感兴趣的饮食变量 包括钠、钾、钙和酒精。少校 这项研究的目的是确定哪些因素会导致 在统计上具有重大意义的重要贡献 低SES黑人的血压水平升高。前期工作 被我们的组织牵连到高约翰·亨利主义(一个强大的 积极应对心理社会的行为倾向 环境应激源)和低社会支持(特别是 工具支持)，作为潜在的重要修饰符 中青年SES/血压关系的研究 黑人。拟议的研究将寻求证实这些 在经济上更加多样化的黑人人口中的协会。在……里面 此外，这项研究将评估习惯性愤怒的程度 抑制以及选定的饮食因素(钠、钾、 等)与血压有关，更具体地说， 影响黑人的SES/血压关系。样本 在大小允许的情况下，预期的SES与John Henryism的相互作用 血压将在社会分层后重新检查 支持、应对愤怒的方式和饮食。 上述研究问题将进行横断面测试， 以血压为连续结果进行线性回归 作为多变量分析技术。但是，样例将 被选择为提供足够数量的正常血压 参加SES前瞻性测试的个人，约翰·亨利主义，以及 三年随访的血压变化。支持 因为这一纵向组成部分将在#年的最后一年寻求 此应用程序中建议的工作。长期目标是 开发血液升高的解释性公共卫生模型 黑色中的压力也可以用来设计有效的 为这一群体的成员提供初级预防方案。

The proposed study will investigate psychosocial and dietary influences on blood pressure in a community probability sample of 25-50 year old Black men and women residing in Pitt County, North Carolina. The psychosocial variables of greatest interest include socioeconomic status (SES), John Henryism, social support and anger-coping style. The dietary variable of greatest interest include sodium, potassium, calcium and alcohol. The major objective of the study is to identify those factors of which make an important and statistically significant contribution to increased levels of blood pressure in low SES Blacks. Prior work by our group has implicated both high John Henryism (a strong behavioral predisposition to cope actively with psychosocial environmental stressors) and low social support (especially instrumental support), as potentially important modifiers of the SES/blood pressure relationship in young and early middle-age Blacks. The proposed study will seek to confirm these associations in a more economically diverse Black population. In addition, the study will assess to what degree habitual anger suppression as well as selected dietary factors (sodium, potassium, etc.) are associated with blood pressure and, more specifically, influence the SES/blood pressure relationship in Blacks. Sample size permitting, the expected SES x John Henryism interaction on blood pressure will be re-examined after stratifying for social support, anger-coping style, and diet. The above research questions will be tested cross-sectionally, with blood pressure as a continuous outcome and linear regression as the multivariable analytic technique. However, the sample will be selected so as to provide a sufficient number of normotensive individuals for a prospective test of SES, John Henryism, and changes in blood pressure over a three year follow-up. Support for this longitudinal component will be sought in the final year of work proposed in this application. The long term objective is to develop explanatory public health models for elevated blood pressure in Blacks that can also be used to design effective primary prevention programs for members of this population.
