Elevated nighttime blood pressure (BP) predicts hypertension and its complications in adulthood.
This study aimed to assess the independent effects of race and family income on night/day BP among adolescents and to examine whether negative emotions, low positive resources, and unpleasant interactions during the day are also related.
Healthy African American and Caucasian high school students (N = 239) wore an ambulatory BP monitor for 48 h, recorded quality of ongoing interpersonal interactions, and completed questionnaires.
African Americans and those with lower family income had higher night/day BP ratios. African Americans reporting greater negative emotions, lower positive resources, and more unpleasant interactions had higher night/day BP ratios.
Racial differences in night BP emerge by adolescence, independent of family income. African Americans, especially those high in negative emotions and low in positive resources, may be at higher relative risk for hypertension later in life in part due to elevated night BP.
夜间血压升高可预测成年期高血压及其并发症。
本研究旨在评估种族和家庭收入对青少年夜间/日间血压的独立影响，并检验负面情绪、积极资源不足以及白天不愉快的人际互动是否也与之相关。
健康的非裔美国人和白人高中生（N = 239）佩戴动态血压监测仪48小时，记录正在进行的人际互动质量，并完成问卷调查。
非裔美国人以及家庭收入较低者的夜间/日间血压比值更高。报告有更多负面情绪、积极资源较少且人际互动更不愉快的非裔美国人夜间/日间血压比值更高。
夜间血压的种族差异在青少年期就已出现，与家庭收入无关。非裔美国人，尤其是那些负面情绪高且积极资源少的人，可能在晚年患高血压的相对风险更高，部分原因是夜间血压升高。
