Objective: to optimize the diagnosis of nutritional status disorders in children born at different gestational periods from mothers with diabetes mellitus by assessing their nutritional status to predict the development of morphofunctional changes in different periods of childhoodMaterials and methods: 84 children from mothers with gestational diabetes mellitus, born in the maternity hospital of the Bauman State Clinical Hospital. The assessment of children’s physical development was carried out in accordance with WHO Anthro standards (2006). A comparative analysis of the variables of children in different groups was carried out using the Student’s T-test. “Statistica 10 programm” was used.Results: preterm children by the age of 3 are not only aligned with full-term children in terms of nutritional status, but also begin to exceed the latter in terms of body weight and length. In further age periods, their indicators do not go beyond the population. In full-term children from 4 years of age, there is a tendency to overweight and obesity.Conclusion: the nutritional status and physical development of children born to mothers with gestational diabetes mellitus depends on the gestational age and undergoes dramatic changes in different age periods of childhood.
