Abstract

RESTREPO MESA, Sandra Lucía et al. Maternal nutritional status and its relationship with birth weight of the newborn, pregnant women study Public Network of Medellín, Colombia. Perspect Nut Hum [online]. 2012, vol.14, n.2, pp.199-208. ISSN 0124-4108.

Objective: to explore the relationship between hemoglobin and maternal body mass index with birth weight. Methods: retrospective study. 336 clinical records from pregnant women were selected. Results: the main proportion of newborns with weights < 3000 g were of pregnant women with low BMI, with significant differences in second (p = 0,0468) and third trimester (p = 0,0126). Birth weight was correlated with maternal BMI at first (r = 0, 19; p = 0,025), and second trimester (r = 0,240; p = 0, 0000). Birth weight was not correlated with maternal hemoglobin at first (r = 0,009; p = 0,900), second (r = 0,011; p = 0,889), nor third trimester (r = 0,005; p = 0,943). There were not differences in birth weight between newborn from mother with Hb<11 g/dL and Hb>11 g/dL. Conclusions: maternal BMI was associated with birth weight; maternal Hb concentration was not associated with the newborn weight.
