Bohn B, et al. - Differences in cardiovascular risk factors and metabolic control were examined in girls with type 1 diabetes with or without the use of oral contraceptives (OC) from the multicentre “diabetes prospective follow-up” registry (DPV). Among adolescent girls with type 1 diabetes, OC use was correlated with a poorer cardiovascular risk profile. Biological risk factors were partly explained by a clustering of sociodemographic and lifestyle factors with a small additional contribution of OC use. Therefore, prescription of OC ought to be combined with a screening for cardiovascular risk factors and targeted education.
