Aim: To investigate whether the mother's weight gain during pregnancy affects the newborn first measured TSH levels. Material and Methods: In Gungoren 30 Ağustos Family Health Center; 112 pregnant and 112 babies were included. The height, weight, and body mass index (BMI) with gestational weeks (gw) of pregnant and birth weight(BW) and TSH levels of newborns were taken. Pregnants were categorized into three groups as normal (BMI<24.9kg/m2), overweight (25.0 30.0kg/m2). Newborns with a TSH value of <5mIU/L as normal, and >5mIU/L as abnormal were classified. Results: The mean age of the pregnant was 27.15.6 years. The gravida was 2.01.0. The weights of pregnant had been measured at 9.02.1 gw in the first trimester and at 35.01.7 gw in the third trimester. It was observed that babies born to overweight mothers in the 1st trimester had the highest BW, while babies born to obese mothers of the 3rd trimester had the highest BW. Mothers with normal BMI in the 1st and 3rd trimesters were younger, and mothers who were overweight and obese were older. The frequency of abnormal TSH was higher in the first trimester BMI<24,9kg/m2 of mothers. There was no relation between the 1st and 3rd trimester BMI of pregnant and neonatal TSH levels. Conclusion: We found that maternal weight gain during pregnancy did not affect neonatal TSH levels but, maternal BMI was closely related to the newborn BW. The importance of follow-up of maternal BMI during pregnancy in addition to standard weight measurements should be emphasized.
