JOHN HENRYISM & HYPERTENSION-RISK IN BLACKS

这项拟议中的研究将调查社会心理和饮食 在社区概率样本中对血压的影响 居住在皮特县的25-50岁黑人男女， 北卡罗来纳州。 最感兴趣的社会心理变量 包括社会经济地位、约翰·亨利主义、社会支持 和愤怒应对方式 最感兴趣的饮食变量 包括钠、钾、钙和酒精。 主要 研究的目的是确定那些因素， 一个重要的和统计上显著的贡献， 低SES黑人的血压水平升高。 先前工作 由我们组已牵连双方高约翰亨利主义（一个强大的 积极科普心理社会问题的行为倾向 环境压力）和低社会支持（特别是 工具支持），作为潜在的重要修饰语， 青年和中年早期社会经济地位与血压的关系 黑人 拟议的研究将设法确认这些 在经济上更加多样化的黑人群体中。 在 此外，该研究还将评估习惯性愤怒的程度， 抑制以及选定的饮食因素（钠，钾， 等等）。与血压有关，更具体地说， 影响黑人的SES/血压关系。 样品 如果规模允许，预期的SES x John Henryism相互作用 血压将在社会分层后重新检查 支持愤怒应对方式和饮食 上述研究问题将在横截面上进行测试， 以血压作为连续结果， 多变量分析技术。 但是，样本将 以提供足够数量的血压正常的 个人的SES，约翰亨利主义的前瞻性测试， 三年随访期间血压的变化。 支持 这一纵向部分将在2004年的最后一年寻求 本申请中提出的工作。 长期目标是 制定解释性的公共卫生模型， 黑人的压力，也可以用来设计有效的 为这一人群提供初级预防方案。

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.
