Comparing Growth and Development of Low and Normal Birth Weight Children at Age of 60 Months

Low birth weight (LBW < 2500 g) is one of the most serious problems in today’s world. It is also a predictor for mortality and stunting.

This study aimed to compare the growth and development at the age of 60 months between children born with low and normal birth weight in Shiraz, Iran.

This study is part of the Fars birth cohort (FBC) study with the data of children who were born in 2011. We called mothers and asked them to bring their children to the FBC clinic for further evaluation. We also determined the level of development at the age of 60 months for each child by using the Ages and Stages questionnaire (ASQ) for the children.

Of the children, 304 (51.4%) were girls. Most of them had normal birth weight (93.2%), had exclusive breastfeeding for five to six months (79.9%), and did not have any chronic diseases (77.8%). Growth indices at the age of 60 months were significantly higher in children with normal birth weight than in their LBW peers (P < 0.001). However, we found no significant difference in children’s development at the age of 60 months between normal and low birth weight children.

Although growth indices of children at the age of 60 months were higher in children with normal birth weight, we found no significant difference in children’s development at the age of 60 months between normal and low birth weight children.
