Lipid profile and its correlates with nutrition and socioeconomic status in adolescent girls in Tabriz high schools

Introduction: Cardiovascular disease is one of the most common chronic diseases in the world. Blood cholesterol, the most important predictor of heart attacks, may increase through childhood and its level in this period is correlated with that in adulthood. This study aimed to assess blood lipid profile and its relationship to dietary intake and socio-economic factors in high school adolescent girls in Tabriz. Materials and Methods: 232 female high school students were selected through stratified random sampling in the city of Tabriz. Demographic and socio-economic status were collected using a self-administered questionnaire and dietary intake data was obtained using a 24-hour recall and two day diet records. From each subject, a 4cc sample of fasting venous blood was drawn. Serum lipids were measured by enzymatic method. Height and weight were measured and BMI was calculated. Results: Mean±standard deviation of triglycerides, total cholesterol, LDL-C and HDL-C were 94.99±42.5, 158.07±42.74, 103.45±40.95 and 36.23±10.51 mg/dL, respectively. Prevalence of hypertriglyceridemia (TG? 200 mg/dL) in these samples was low (less than 3 percent), while hypercholesterolemia (TC>_200 mg/dL), high LDL-C (LDL-0130 mg/di.), and low HDL-C (HDL-0535 mg/dL) were seen in 16.4%, 21.1% and 54.7%, respectively. No associations were observed between dietary intake, socio-economic status and serum lipid levels in the samples. However, a significant correlation was observed between BMI and TG (r= 0.23, P= 0.01), TC (r= 0.29, P= 0.01) and LDL-C (r- 0.22, P= 0.01). Conclusion: High prevalence of overweight and hyperlipidemia in the studied adolescents, emphasizes the need for monitoring and intervention to decrease and control serum lipids in this group. Body mass index is the most important factor that correlates with increase in blood lipids in the studied sample.
