Implication for practice
The present study will provide findings about the utility of a very easy tool of nutritional screening to evaluate the most relevant nutritional deficiencies in pregnancy, with impacts on the first stages of placentation and pregnancy outcome, in a large Italian population of singleton pregnancies. A multicenter prospective observational study involving 22 Maternity Units would therefore make a significant contribution to this topic and public health, with a possible impact on future clinical routine care.
