Cardiovascular risk factors in schoolchildren

Area of Science:

• Pediatrics
• Cardiology
• Public Health

Background:

• Cardiovascular risk factors are increasingly prevalent in children and adolescents.
• Early identification and management of risk factors are essential for long-term cardiovascular health.
• Screening programs can help detect conditions like hypercholesterolemia and hypertension in young populations.

Purpose of the Study:

• To assess the prevalence of cardiovascular risk factors in a large cohort of German students.
• To analyze the relationship between total cholesterol (TC) levels and various factors including age, sex, weight, and oral contraceptive use.
• To emphasize the importance of cardiovascular risk factor screening in children and adolescents.

Main Methods:

• Screening of 1470 students aged 7-22 years in Berlin, Germany.
• Assessment of cardiovascular risk factors: hypercholesterolemia, hypertension, obesity, smoking, and family history.
• Statistical analysis of total cholesterol (TC) levels in relation to sex, age, weight, and oral contraceptive use.

Main Results:

• Only 56% of students had no modifiable cardiovascular risk factors.
• 16% had elevated total cholesterol (TC > 200 mg/dl), 12% had hypertension, and 21% were overweight.
• TC levels showed age dependency in both sexes, with variations between age groups and significant differences between boys and girls. Girls using oral contraceptives had higher TC levels. Obesity did not influence TC.

Conclusions:

• A significant proportion of young individuals exhibit cardiovascular risk factors.
• Total cholesterol levels are influenced by age, sex, and oral contraceptive use in adolescents.
• The findings strongly support the necessity of routine screening for cardiovascular risk factors in children and adolescents.
