The proposed study is a longitudinal investigation of social, dietary, and anthropometric predictors of changes in blood pressure in a large, economically diverse southern, Black population. Study participants (665 men, 1,119 women) were between 25-50 years of age in 1988, the year of the baseline survey, and resided in Pitt County, NC. This community is part of a region in the southeastern U.S. known to have elevated mortality from coronary heart disease and stroke. Efforts will be made to re-interview the 1,429 respondents (571 men, 912 women) with untreated, mean diastolic blood pressure < 95 mmHg at baseline, and again at follow-up, on changes in blood pressure during the intervening 4-5 years (1988-1992/93) will be examined. The social variables include socioeconomic status (SES), John Henryism, stress, and social support; the dietary variables include alcohol, sodium, potassium, and calcium; and the anthropometric variables include body mass index (BMI) and waist/hip ratio (WHR). With an emphasis on SES, physical activity, dietary habits, and cigarette smoking, the predictors of weight gain, and changes in patterning of body fat will also be examined. Multiple linear regression will be the primary analytic tool used to study these longitudinal relationships. In cross-sectional analyses which control for physical activity and other important variables, the role of insulin resistance in mediating associations between obesity and blood pressure, and stress and blood pressure, will also be examined. Thus this study aims to clarify interrelationships among social, behavioral, and biological determinants of hypertension in Black Americans. Study findings will be used to plan clinical and public health interventions in this and other similarly high risk Black populations.

拟议的研究是对社会，饮食和 人体测量学预测指标的大型血压变化 经济多样化的南部，黑人人口。 研究参与者（665 男性，1,119名女性）在1988年25-50岁之间 基线调查，居住在北卡罗来纳州皮特县。 这个社区是 美国东南部的一个地区，已知来自 冠心病和中风。 将努力重新审视 1,429名受访者（571名男性，912名女性）未经治疗，平均舒张压 基线时的血压<95 mmHg，然后在随访时再次发生变化 在中间4 - 5年（1988-1992/93）中的血压将为 检查。 社会变量包括社会经济地位（SES），约翰 亨利主义，压力和社会支持；饮食变量包括 酒精，钠，钾和钙；和人体测量变量 包括体重指数（BMI）和腰围/髋关节（WHR）。 重点 关于SES，体育锻炼，饮食习惯和吸烟， 体重增加的预测因素，体内脂肪模式的变化也将 被检查。 多个线性回归将是主要的分析工具 用于研究这些纵向关系。 在横截面 控制体育活动和其他重要变量的分析， 胰岛素抵抗在肥胖之间介导关联中的作用 还将检查血压以及压力和血压。 因此，这项研究旨在阐明社会， 黑人美国人的行为和高血压的生物决定因素。 研究发现将用于计划临床和公共卫生 对此和其他类似高风险黑人人群的干预措施。
