a
Model controlling for type of micronutrient intervention (p > 0.05): Iron (60 mg) + 400 g folic acid (reference); Iron (30 mg) + 400 g folic acid; and Multiple micronutrients (MMN) that included 15 recommended micronutrients, including iron 30 mg, as described by Persson et al. (2012).
b
Cortisol obtained at 28-32 wk gestation and was continuous.
c
Invitation time to start food supplementation program was either early (~9 wk gestation) or usual (~20 wk gestation).
