Cardiovascular fitness among children has been shown to predict adult cardiovascular fitness. This study examined cardiovascular risk factors of 100 randomly selected adolescents, ages 15 to 18, in a suburban high school of a large western metropolitan city. Respondents were middle to upper-middle socioeconomic class and almost exclusively Caucasian.A survey was used to assess the prevalence of six cardiovascular risk factors in this adolescent sample. The six risk factors were family history of diseases associated with increased cardiovascular risk, smoking, lack of exercise, elevated blood pressure, obesity, and stress. The prevalence of these factors in the adolescent sample is reported using descriptive statistics. In addition, sex comparisons were made on the modifiable risk factors. The findings from this study were compared to national statistics. Implications of these findings are discussed.
