Demographic Correlates of Infant Feeding Practices and Growth Performance in the First Year of Life

Figure 1

Rate of weight gain between birth and 6 months of age for breastfed, formula fed, and mixed fed infants (n=92). The rate of weight gain was calculated as weight-for-age z-score at 6 months of age minus weight-for-age z-score at birth. Values are percentages of infants in weight gain categories based on weight-for-age z-score change as slow (<-0.67), gradual (-0.67 to 0.67), or rapid (>0.67). We excluded the 35 infants who were complementary fed (and also previously fed by the alternate FP), there were 37 infants in total who experienced rapid weight gain by 6 months of age; again, FP and type of weight gain were related (χ², p<0.05).
