plasma continine level and lipid profiles in passive smoking school children

It’s known that cigarette smoking is associated with elevation of plasma lipid levels and changes in lipoprotein distribution, it’s not known whether passive smoking is associated with alteration in lipid profiles or not. The aim of the work is to study the effect of passive smoking on lipid profiles in school children which is a predictive for increased risk of a cornary therosclerosis.This work aimed at studying the effect of passive smoking on lipid profiles in school children.Assessment of lipid profiles was done for 68 Children exbosed to ETS with age ranged 10-15 years. They were 36 boys their mean age (11.94 years) and (32)girls their mean age (11.98 years). A non exposed group surved as control. It consists of 24 child included (10) boys their mean age (12.62 years) and (14)girls their mean age (12.34 years) with comparable socio-economic status and atheletic activity. plasma cotinine level was taken as a marker of exposure to tobacco smoke. Lipid profiles were assayed by fasting plasma level of triglycerides, total-C, HDL-C, total-C/HDL-C ratio and LDL-C.
