The major aims of our ongoing research have been: (a) to identify the early emergence and stability of children's hostile behaviors and their concomitant psychophysiological responses to stress, which may be risk factors for cardiovascular disease in adulthood; and (b) to specify their determinants. Our past studies examining the Type A behavior pattern, hostility, physiological responses and family interactive behaviors have primarily involved White, upper-middle class children and parents. We propose to extend our program of research to include the study of Black children and those from lower-middle to middle class families. This extension is important not only because these groups have been understudied, but also to examine developmental factors that may be important in accounting for the much higher incidence of hypertension and related disorders in Blacks and in lower and lower-middle class groups. However, we are adopting a somewhat different strategy of inquiry for the present proposal. Specifically, we will: (1) study the patterns of cardiovascular responses exhibited by Black and White children in order to better assess hemodynamic and autonomic nervous system mechanisms that underlie these responses; (b) examine how these hemodynamic patterns relate to cardiovascular risk factors such as body fat distribution, left ventricular geometry (via echocardiography), as well as insulin, glucose, and lipid levels; and (c) to explore a new conceptualization of hostility indices and cardiovascular risk factors. 160 Black and White children and adolescents of both genders will be recruited for participation, half being pre-pubescent (9-10 years old) and half being post-pubescent (15-16 years old). The first laboratory session will consist of a fasting venous blood draw, collection of anthropomorphic data, a psychophysiological stress protocol involving four tasks selected to elicit different autonomic nervous system responses, and completion of standardized questionnaires to assess hostility and social support. A second session will involve an echocardiographic assessment of left ventricular geometry and cardiac performance variables, the Type A Structured Interview, and an interview examining how subjects process information about hostile intentions and actions of others. The proposed project attempts to add significantly to the understanding of etiology of Black-White and social class differences in cardiovascular risk factors, and the role of hostility in this development.

我们正在进行的研究的主要目的是：（a）确定 儿童敌对行为的早期出现和稳定性， 伴随的心理生理反应的压力，这可能是风险 成年期心血管疾病的因素;以及（B）指定其 决定因素 我们过去对A型行为模式的研究 敌意、生理反应和家庭互动行为， 主要涉及白色，中上层阶级的孩子和父母。 我们 我建议扩大我们的研究计划，包括对布莱克的研究 孩子和那些来自中下层到中产阶级家庭的人。 这 扩展是重要的，不仅因为这些群体已经 研究不足，但也要检查发展因素， 在解释高血压的高发病率方面很重要， 相关疾病的黑人和较低和较低的中产阶级群体。 然而，我们正在采取一种有点不同的调查策略， 目前的提案。 具体而言，我们将：（1）研究 黑人和白色儿童表现出的心血管反应， 更好地评估血流动力学和自主神经系统机制， 这些反应的基础;（B）检查这些血流动力学模式如何相关 心血管危险因素，如身体脂肪分布，左 心室几何形状（通过超声心动图），以及胰岛素，葡萄糖， 和脂质水平;以及（c）探索敌意的新概念 指数和心血管危险因素。 160名黑人和白色儿童， 将招募男女青少年参加，其中一半是 青春期前（9-10岁）和一半青春期后（15-16岁 旧）。 第一次实验室检查将包括空腹静脉血 画，拟人数据的收集，心理生理压力 协议涉及四个任务选择，以引起不同的自主 神经系统反应，并完成标准化问卷， 评估敌意和社会支持。 第二次会议将涉及一个 超声心动图评估左心室几何形状和心脏 绩效变量、A型结构化面试和面试 研究受试者如何处理有关敌对意图的信息， 其他人的行动。 拟议项目试图大大增加 对黑白人种病因学的认识与社会阶层差异 在心血管危险因素中的作用，以及敌意在其中的作用。 发展
