ABSTRACT

BACKGROUND: Cardiovascular risk factors begin in childhood and adolescence. This study aimed at assessing serum lipids and prevalence of Dyslipidemia in 11-18 year old students of Birjand. METHODS: The present cross-sectional, descriptive, and analytical study was done on 2,643 middle and high school students of Birjand aged 11-18 years (1,396 girls and 1,247 boys). Blood samples were collected for the measurement of blood lipids, including Cholesterol, Triglyceride, HDL, and LDL after a 12-hour fasting period.

RESULTS: According to our results, it is concluded that (i) 34.3% (31.3% girls and 37.6% boys) of adolescents had at least one dyslipidemia. (ii) 24.7% of the individuals had HDL lower than 40, where 14% of them TG≥130, 6.1% of cases TC≥200, and 3.5% of cases LDL≥130. Lipid disorder within low HDL type and hypertriglyceridemia were significantly higher in boys (P<0.05) than girls. Hypercholesterolemia and hypertriglyceridemia in the age group of 11-14 years and low HDL in the age group of 15-18 years showed the highest values (P<0.05). CONCLUSION: Adolescents of Birjand have high prevalence of dyslipidemia. Preventive measures are recommended to improve lifestyle, including healthy nutrition, encouraging adolescents to exercise, and more mobility.
