Abstract: Objective To investigate the physical growth level and its difference of infants with different feeding patterns. Methods Data on breastfeeding, complementary feeding and physical growth in infants aged 1-<12 months were collected through the fifth physical development survey of children under 7 years old in nine cities of China in 2015. Feeding patterns for infants aged 1-<6 months were classified into exclusive breastfeeding, partial breastfeeding and formula feeding, and for infants aged 6-<12 months into continued breastfeeding and formula feeding. Weight, length and head circumferences were assessed among different feeding groups using analysis of variance or t test. Results A total of 59,170 infants aged 1-<12 months were included in this study. For infants aged 1-<6 months, exclusive breastfeeding, partial breastfeeding and formula feeding accounted for 48.6%, 37.4% and 14.0% respectively and for infants aged 6-<12 months, continued breastfeeding and formula feeding accounted for 59.9% and 40.1% respectively. At the age of 1-<6 months, exclusively breastfed infants were a little heavier than partially breastfed infants with the difference from 0.06 to 0.20 kg, and also a little heavier than formula-fed infants with the difference from 0.09 to 0.22 kg. At the age of 6-<12 months, continuously breastfed infants were a little shorter than formula-fed infants with the difference from -0.3 to -0.1 cm. Weight at 6-<12 months, length at 1-<6 months, and head circumferences at 1-<12 months were almost not of statistical significance among different feeding groups. The growth of weight, length and head circumferences for infants with different feeding patterns generally conformed to child growth standards required by World Heath Organization, but the average growth levels of weight and length were slightly higher. Conclusion Infants with different feeding Methods presented similar growth patterns in infancy. The growth performance of exclusively breastfed infants was slightly higher than that of partially breastfed and formula-fed infants in the first half of the first year, but the growth performance of continuously breastfed infants was slightly lower than that of formula-fed infants in the second half.
