Correlation between gestational age and birth weight and graphical representation of the 10th and 90th percentiles for females (A) and males (B) based on Brazilian-specific growth curves.

<p>SGA: Small for gestational age (< 10th percentile); AGA: Appropriate for gestational age (10th-90th percentile); LGA: Large for gestational age (>90th percentile); LBW: Low birth weight (<2500 g); Premature newborn (< 37 weeks). The intra-uterine growth retardation (IUGR) was defined as the newborn SGA. No differences were found by gender to IUGR (p = 0.686), LBW (p = 0.406) and prematurity (p = 0.968).</p
