  1. 1 Linear regression analysis for birth weight as dependent variable and interpregnancy interval in categories as independent variable; logistic regression analysis for SGA as dependent and interpregnancy interval in categories as independent variable. SGA was defined as birth weight < 10th percentile for gestational age based on sex- and parity-specific standards. n=1659 mother-infant pairs. None of the selected maternal and infant characteristics acted as confounding factors.
  2. 2 Analysis adjusted for all four selected fatty acids together.
  3. 3 Significantly different from reference category (18–23 mo) p<0.005.
  4. 4 Significantly different from reference category (18–23 mo) p<0.05.
