Objective: To assess lipid profile and nutritional parameters from adolescents with family history of premature coronary artery disease (CAD) and assess the effects of nutritional counseling.
Methods: The study included 48 adolescents of both gender and with ages ranging from 10 and 19 years old (case group, n=18; control group, n=30).
Results: Offspring of young individuals with coronary artery disease showed higher values of total cholesterol (189 +/- 30 vs. 167 +/- 26 mg/dl, p < 0.01), LDL-C (144 +/- 20 vs. 100 +/- 27 mg/dl, p < 0.001) and apoB (80 +/- 15 vs. 61 +/- 18 mg/dl, p = 0.001) and lower values of HDL-C (45 +/- 9 vs. 51 +/- 13 mg/dl, p < 0.02) than control young individuals. Differences were not found for triglycerides and apoA-I. With a dietotherapeutic counseling, we obtained a reduction in alimentary consumption of saturated fatty acids (pre: 15.5 +/- 4.7% vs. post: 6.6 +/- 3.7%, p = 0.003) and an improvement in lipid profile: TC (-8%, p = 0.033), LDL-C (-18.2%, p = 0.001), TG (-53%, p = 0.002) rates in offspring of premature CAD patients who showed hyperlipidemia.
Conclusion: The presence of dyslipidemia was more prevalent among offspring adolescents of premature CAD patients, but it was responsive to nutritional intervention.
