Circulating Insulin and IGF-1 and Frequency of Food Consumption during Pregnancy as Predictors of Birth Weight and Length

The aim of the study was to assess the relationships between maternal insulin and insulin-like growth factor-1 (IGF-1) concentration and food consumption frequency and the birth parameters of the newborn. A total of 157 mother-newborn pairs participated in the study. The study showed that more frequent consumption of sweet and salty snacks as well as fruit and fruit or vegetable juices may promote greater weight gain in pregnancy and higher newborn birth weight. A significantly higher insulin concentration was found among overweight women according to body mass index (BMI), and a significantly lower concentration of IGF-1 was demonstrated among women >= 35 years of age. There was no significant correlation between the concentration of insulin and IGF-1 in the mother's blood plasma and the birth weight and length of the newborn. A significant relationship was only found between the concentration of IGF-1 in the mother's blood and the Ponderal index of the newborn. A woman's eating habits during pregnancy have a significant impact on the mother's health and on the proper growth and development of the foetus.

Automated summary

The study focused on assessing the relationships between maternal insulin and IGF-1 concentration, food consumption frequency, and newborn birth parameters. It found that frequent consumption of sweet and salty snacks, as well as fruit and fruit or vegetable juices, may lead to greater weight gain in pregnancy and higher newborn birth weight. Additionally, the study showed that overweight women had higher insulin concentrations and women over 35 years old had lower concentrations of IGF-1.
