[Biological status of adolescent girls using estrogen-progestins]

Frequently adolescents use oral contraceptives (OP). Measures of some biological and metabolical patterns were performed in a sample of 339 young girls under going periodic health examination at Pasteur Institute in Lille. A case control study showed lower glucose level, and lower quantity of red blood cells and hemoglobin in OP users. Variance analysis showed lower GGT and TGO with "Gestodene", "Desogestrel" and "Norgestimate" than with the older progestatives (but cigarette smoking seems to influence these datas). Conclusion claims that new progestatives have the best biological tolerance.
