چکیده
INTRODUCTION At present, about 1% of newborns are delivered through assisted reproductive technologies (ART) worldwide. This study aimed to evaluate and compare the growth parameters of children born in assisted and natural conception at 5 years of age. MATERIALS AND METHODS In a cross-sectional case control study, weight, height and head circumference of 5-year old children were assessed. The case group consisted of term, singleton babies who were products of ART in the Center for Infertility of Shahid Sadoughi University, Yazd, Iran in 2005. The control group consisted of term, fi rst child, singleton and spontaneously conceived 5-year-old children who were referred for vaccination to primary health care center of Shahid Akbari in 2010. RESULTS Fifty-eight girls (47.5%) and 64 boys (52.5%) "with equal numbers in each of the 2 groups" were evaluated. Sex distribution, mean ages of fathers and mothers were not statistically significant different in both groups. Children born after ART tend to have lower birth weight, smaller birth head circumference and lower weight at 5 years of age. Having low birth weight (<2500 g), being underweight and having short stature at the age of 5 were more common in babies born through ART. CONCLUSION Growth retardation is more prevalent in babies born through ART. Thus, growth assessment, parents' knowledge about child physical development, and timely and accurate follow-up of these children are necessary for early detection of any growth disorders.
