The objective of this study was to assess the relationship between consumption of different
types of carbohydrates (CHO) during pregnancy and the risk of having a small for gestational
age (SGA) newborn. A retrospective matched case–control design was carried out with a total of
518 mother-offspring pairs. A total of 137 validated items were included in the food frequency
questionnaire (FFQ). Conditional logistic regression models were used to calculate crude odds
ratios (cORs) and adjusted odds ratios (aORs) with 95% confidence intervals (CIs). Having more
than 75 g/day of brown bread showed an inverse association with SGA (aOR = 0.64, CI 0.43–0.96).
In contrast, an intake of industrial sweets more than once a day (aOR = 2.70, CI 1.42–5.13), or even
2–6 times a week (aOR = 1.84, CI 1.20–2.82), increased the odds of having a SGA newborn. During
pregnancy, the higher the increase of wholegrain cereal and bread, the lower the possibility of having
a SGA newborn, but the opposite occurred with refined sugar products—just consuming industrial
bakery products or pastries twice a week increased the odds of having an SGA infant. Case–control
studies cannot verify causality and only show associations, which may reflect residual confusion
due to the presence of unknown factors. It is possible that a high consumption of sugary foods is a
marker of a generally poor lifestyle.
