Introduction: Different diets during pregnancy might have an impact on the health as reflected by the birthweight of the newborn. The consumption of meat and meat products during pregnancy and its relationship with the newborn health status have been studied by several authors. The studies carried out show inconsistent results Objective: To analyse the association between maternal dietary intake of meat and meat products on the risk a newborn SGA. Methods: A matched case-control study of 518 cases and controls of pregnant women was performed in Spain. Cases were women with a SGA newborn. Data about demographic characteristics and diet were collected. Meat consumption was gathered through a validated food frequency questionnaire. Meat and meat products intake were categorized in quintiles (Q1-Q5).The association between maternal meat and meat product intakes and SGA was assessed by logistic regression models with adjustment for confounding factors.Results: An intake of meat products above 6.8 g/day  was associated with a lower risk of SGA delivery (OR= 0.7; 95% CI, 0.53-0.93) after adjusting for smoking, body mass index, previous preterm-low birthweight, newborn’s gender and adherence to Mediterranean diet.  Conclusions: Meat consumption was not associated with SGA, whereas meat products showed a moderate protective relationship.
