Abstract
A high-risk pregnancy (HRP) is one with either an abnormal or pathologic condition, concomitant to gestation or delivery, that threaten the life or health of the mother or fetus [1]. Prevalence of HRP has been reported between 12% and 60%, depending on the country. Some of the risk factors leading to an HRP are woman´s age, nutritional status (diet), diabetes, autoimmune disorders, hypertension, infectious diseases, history of chronic disease and complications in previous pregnancy, multifetal pregnancies and less than 1-year gestational interval [1-3]. A compromised maternal nutrition can result in an adverse outcome of pregnancy and childbirth [4-7]. A clear relationship between maternal malnutrition and adverse pregnancy outcome has been accepted.
