Blood Lipids, Cardiovascular Fitness, Obesity and Blood Pressure The Presence of Potential Coronary Heart Disease Risk Factors in Adolescents Academic Article uri icon

abstract

  • OBJECTIVE: To identify and compare the presence of coronary heart disease (CHD) risk factors among 14- and 15-year-old boys and girls. DESIGN: For this cross-sectional study of 54 subjects, a blood sample taken after subjects fasted was used to determine total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglyceride concentrations. Dietary intake was estimated using a 24-hour recall and a 2-day food record. Height, weight, and skinfold thicknesses were measured to identify obese and severely obese subjects. Cardiovascular fitness, blood pressure, and cigarette use also were measured. TC, HDL-C, LDL-C, fitness, blood pressure, and smoking are modifiable risk factors, for CHD. SUBJECTS: Adolescents were selected by random sampling from lists of students attending public schools in two central Texas cities. Adolescents who were 14 or 15 years old; were not pregnant; and had no history of high blood pressure, diabetes, or heart disease were eligible to participate. STATISTICAL METHODS: Data were analyzed using Student's t and chi square tests. RESULTS: Of the subjects, 25% demonstrated two or more risk factors for CHD. A significantly higher percentage of girls than boys had a TC concentration greater than 5.2 mmol/L. Boys (n=29) had a mean fitness score that indicated a higher level of cardiovascular fitness than girls (n=25); however, the mean score for both groups was below average. CONCLUSION: Data provide support for increased interventions targeted toward lowering the risk factors for CHD and other chronic diseases in adolescents.
