Total blood cholesterol (TBC) levels and contributory risk factors in an adolescent population were investigated. Existing TBC screening records were reviewed on 452 10th grade students in two schools. The sample consisted of 52% males and 48% females whose mean age was 15.47 years. Blood samples were analyzed by the Reflotron. Risk factors investigated included age, gender, ethnicity, individual and family history of high cholesterol, history of high blood pressure, smoking tobacco products, and oral contraceptive use. The sample mean for TBC was 150.61. The only significant factors identified by ANOVA were gender and use of oral contraceptives. Females had higher TBC levels than males, and females who used oral contraceptives had higher TBC levels than nonusers.

PIP: Total blood cholesterol levels were screened by a fingerstick-desktop method in 452 10th grade students from 2 schools as part of a cholesterol task force that included health education on risk factors. The children averaged 15.47 years. The Reflotron analyzer (Boehringer Mannheim Diagnostics) used non-fasting blood. The overall mean TBC level was 150.61 mg/dl. By risk groups, 76% were low risk, with TBC levels ranging from 100-169; 11% were moderate risk, ranging 1270-185; and 12% were high risk, with levels ranging from 170-400. Girls' levels averaged 160.15, significantly higher than boys' 141.95, consistent with prior published reports. The 10 girls using oral contraceptives had a mean TBC of 188.20, compared to 158.85 for nonusers. There were no significant differences for other potential risk groups: ethnicity, history of high blood pressure, current smoking, individual or family history of high cholesterol. School A had a higher socioeconomic background than School B. The mean cholesterol level for School A was 149.02, compared to 152.08 for School B. Schools need more health education on risk factors and lifestyle, and preventive health intervention.
