Efficacy of a school-based cardiac health promotion intervention program for African-American adolescents.
OBJECTIVE African-American adolescents are twice as likely to develop hypertension in early adulthood than adolescents from other racial groups . The purpose of this study was to determine the efficacy of a school-based health promotion intervention . METHOD Participants were African-American adolescents aged between 14 and 17 years attending an urban high school . The 9-week intervention program focused on the participants ' knowledge , diet , exercise , and blood pressure . CONCLUSIONS The intervention program was efficacious in knowledge ( p = .0001 ) , exercise ( p = .0001 ) , as well as fruit and vegetable intake ( p = .0001 ) . Differences in systolic ( p = .5548 ) and diastolic ( p = .9719 ) blood pressure levels were not significant
