Cross-sectional associations between self-reported hours of television (TV) viewing per day and cardiovascular risk factors were assessed in a biracial (black and white) study population of 4280 men and women, ages 23 to 35 years, undergoing the year-5 follow-up examination for the Cardiovascular Risk Development in Young Adults (CARDIA) study in 1990 to 1991. Number of hours of TV viewing per day was higher in blacks than in whites and was inversely associated with education and income. Relative to "light" TV viewers (0 to 1 h/d), "heavy" TV viewers (> or = 4 h/d) had a higher prevalence (P < 0.05) of obesity, smoking, and high hostility score in all race/gender groups, and of physical inactivity in all groups except black men. Among whites, "heavy" TV viewers had higher depression scores, and among blacks, reported more alcohol use. TV viewing was not associated with hypertension and lipid abnormalities. Heavy TV viewing is a modifiable behavior that is associated with increased prevalence of several cardiovascular risk factors.
在一项针对4280名年龄在23至35岁之间的黑人和白人混血研究人群的研究中，评估了自我报告的每日看电视时长与心血管危险因素之间的横断面关联。这些人群于1990年至1991年参加了青年成人心血管风险发展（CARDIA）研究的第5年随访检查。黑人每日看电视的时长高于白人，且与教育程度和收入呈负相关。相对于“轻度”电视观众（0至1小时/天），“重度”电视观众（≥4小时/天）在所有种族/性别组中肥胖、吸烟和敌意得分较高（P<0.05），在除黑人男性外的所有组中身体活动不足的患病率较高。在白人中，“重度”电视观众的抑郁得分较高，在黑人中，报告的饮酒量较多。看电视与高血压和血脂异常无关。大量看电视是一种可改变的行为，与多种心血管危险因素的患病率增加有关。
