Normal lipoprotein profile of adolescent students

ABSTRACT

We planned this work to establish the arbitrary normal values of total cholesterol [TC], low density lipoprotein [LDL-C], high density lipoprotein - cholesterol [HDL-C], and triglycerides [TG] among school adolescents, [aged 14 - 21 years] in Mansoura district, 341 normal adolescent students were enrolled in the study through a related questionare including their socio-demographic data.Out of them 201 were sampled for laboratory studies after their constant. The mean values of TC, LDL-C, HDL-C and TG in males were 155.4, 85.8, 51.3 and 79.6 mg/dl respectively. Their 5th to 95th percentiles were [108.2-219.5], [38.1-138.0], [36.0-70.9] and [32.5-161.7] mg-dl respectively. In females, the corresponding mean values were [123.3-233.8], [57.6-187.2], [32.073.8] and [40.3-134.2] mg/dl respectively. Our levels were compared with the western levels. There were no significant difference regarding variations of these parameters related to their sex, residence, social class or smoking.We hope such data to be of benefit in the determination of the preliminary cut -off values at which the risk of coronary artery disease [CAD] is increased. This will be clearly of help for the ultimate purpose of preventing such disorder later on in life
