Despite evidence that pregnancy planning improves outcomes, in Italy, as in many other countries worldwide,50% of women with diabetes prepare their pregnancy. The aim of this study was to document training and knowledge on diabetes and pregnancy (DP) among diabetes professionals.We administered an anonymous online questionnaire, focused on diabetes and pregnancy planning, to diabetes team members. Between Nov-2017 and Jul-2018, n = 395 professionals (60% diabetes/endocrinology/internal medicine specialists, 28% fellows) completed the survey. Fifty-nine percent of the specialists, mainly (78%) those completing their fellowship after 2006, reported having received training on DP during fellowship. Considering specialists reporting training, 43% correctly identified fetal risks of inadequate preconceptional glucose control and 55% maternal risks, 38% identified risks associated with overweight/obesity, and 39% would prescribe hormonal contraception to women with diabetes only if glucose control is good.The results of our survey suggest the need to improve training and awareness of professionals in the area of diabetes and pregnancy.
