Background: Intrauterine growth retardation (small for gestational age (SGA)) is connected with perinatal morbidity, neurological pathology and stature.

Objective and hypotheses: The aim of our study is to estimate the incidence of SGA and its consequences in newborns and infants at the age 1.

Method: The incidence of SGA among newborns in the Udmurt Republic (the region of the European part of the Russian Federation) has been studied. SGA has been diagnosed according to National standards: birth weight and/or length below the 10th percentile for gestational age.

Results: 208 155 infants were born in the republic during the period of 2005–2014. High incidence of SGA (151.9±0.8/1000 newborns) has been observed, including in full-term newborns 153.7±0.7 and premature 122.6±3.0 (P<0.001). There is a trend towards a reduction in the incidence of SGA in recent years: within the period of 2005–2010 – 160.9±1.1; within the period of 2011–2014 – 140.2±1.2 (P<0.001). Clinical examination of 500 newborns has shown that SGA is connected with perinatal pathology of the nervous system (84.8±1.6%), perinatal infections (50.6±2.2%), and metabolic disorders (26.0±1.9%). SGA consequences in infants at the age of 1 are the low rates of physical development (22.8±1.9%).

Conclusion: Our study indicates the high incidence of SGA that involves other medical problems.
