Purpose Although bariatric surgery is associated with a decrease in obesity complications, it may affect the children’s growth by a maternal nutritional deficiency. This study was conducted to assess the effect of maternal bariatric surgery on offspring anthropometry. Materials and Methods In a mixed cohort, anthropometric status of children aged 5 years or less born to mothers with a history of bariatric surgery was compared with a control group consists of peers born to mothers with obesity but without bariatric surgery. Anthropometric indices including crude and quantile values for BMI, weight, height, and head circumference at birth and the first 5 years of life were measured. Then, the adjusted effect of maternal surgical history on anthropometric status was estimated by linear regression. Results From a total of 56 children, 28 born to mothers with a history of bariatric surgery, and 28 born to mothers with obesity but without bariatric surgery. At birth, weight (2915 vs 3225 g) and BMI (11.72 vs 12.94 kg/m 2 ) were lower in the group with maternal bariatric surgery than in the control group ( P  = 0.02 and P  = 0.03, respectively), although after regression adjustment, there was only a significant difference between the two groups in height for age value in children less than 5 years old ( B  = 0.872, P -value = 0.001). Conclusion Bariatric surgery with decrease of weight indices at birth has a probable influence on growth and development in next years. Therefore, it is recommended further studies to identify unknown effect of types of preconception surgical procedures on childhood outcomes.
