title: [Blood screening of glucose and lipid disorders as coronary atherosclerosis risks factors in French adolescents 16 to 19-20 years old].
abstract: A screening of fasting blood glucose and lipids disorders, presumely linked to premature atherosclerosis namely affecting Coronary arteries, has been performed among 599 adolescents of both sexes with the goal of establishing the actual prevalence of these disorders in French population recruited through different areas of the country. All of them were between ages of 16 and 19-20 years old, and invited to give, in total gratuity, their blood samples to private and accreditable laboratories close to their living habitation. After 262 exclusions due to either previous screening not signaled before or present use of contraceptive pill in girls, only 202 boys and 135 girls remained eligible for such a prevalence study. Using plasma enzymatic dosages of CT, HDL C, (calculated) LDLC, TG, and blood glucose, cut off points for each of these parameters, were analysed as well as calculated international index of CT/HDLC and CT minus HDLC. But the first one index was shown the best tool for the final estimation of the frequency of lipid disorders, which requires primary prevention. Indeed, despite of a rather high frequency of overlaps of CT and LDLC respectively found at 16.3 and 22.5% for boys, and 27.3 and 27.5% for girls, the still higher increase of frequency of HDL C at 31% for boys and 28.1% for girls has shown a very significant compensation of these previous increases. In such a way as the authentic prevalence of atherogenic lipid disorders is found reduced in boys to 8.4% and in girls to 7.4% for CT/HDLC>/=4.5 ratio, and to 5.4% in boys and 5.2% in girls for CT less HDLC. A Familial Dominant Hypercholesterolemia was discovered only two times in two girls 16 years old. Other abnormal lipid profiles were rather those of Mixed H., type IV, chiefly mild Hypercholesterolemia, and some rare cases of HypoHDLemia. The only greater linked cardiovascular risk factor was direct parental C.V. heredity, round 30% among lipid disorders. Obesity remained rare, as well as Metabolic Syndrome in the present recruitment. Contraceptive pill increases significantly all lipid parameters and atherogenic index: chiefly CT minus HDLC which reaches almost the double of frequency (15%) versus that of girls without pill. But 53% of boys with proatherogenic lipid disorders are smokers, while only 10% of these dyslipidemic girls smoke.
