Smoking and apolipoproteins in adolescents. The Niño Jesus Group.
The relation between smoking and blood lipids and apolipoproteins (A1,B100) were studied in a group of 1024 12- to 18-year-old school children in the Comunidad de Madrid. The percentage of smokers was 19% (17% for girls and 21% for boys). The average consumption of cigarettes per day was 7.83 +/- 5.06 in boys and 6.04 +/- 3.49 in girls (p less than 0.05). As compared with male nonsmokers, male smokers showed a higher mean level of low-density lipoprotein (LDL) cholesterol (112 versus 100 mg/dL, p less than 0.05), a higher LDL cholesterol to HDL-cholesterol ratio (2.27 versus 1.94, p less than 0.001), a higher mean level of apolipoprotein B100 (59 versus 53 mg/dL, p less than 0.05), and a higher apolipoprotein B100 to apolipoprotein A1 ratio (0.45 versus 0.40, p less than 0.01). Female smokers tended to show the same results, although significant differences were only found for LDL cholesterol to HDL cholesterol ratio and apolipoprotein B100 to apolipoprotein A1 ratio (1.8 versus 1.59 and 0.41 versus 0.38 respectively, both p less than 0.05). This work provides new data about the effects of smoking on apolipoproteins in adolescents and emphasizes on the need for preventive programs.
