摘要:
In a previous study, we reported that black children demonstrated greater cardiovascular reactivity than did white children to the psychological stress of a television video game. Reliance on urban volunteers and the wide age range of the children may have limited conclusions concerning the generalizability of those results. In the present study, 481 of 484 children enrolled in the third grade of the public schools of an entire rural county in Tennessee were examined with the same video game procedure used previously. Results indicated greater heart rate and blood pressure reactivity among black children than among white children. Thus, the previous results were replicated. The greater prevalence of hypertension among black adults may relate to the greater reactivity among black children; reactivity may be either a marker or a mechanism in the development of hypertension.
