Antenatal, CUG, IUGR, Postnatal


Background: The burden of IUGR is concentrated mainly in Asia with the proportion of IUGR 54% in India. Higher rates of IUGR should be a cause of concern because they signal high risk of malnutrition, morbidity and mortality for the new born. This study was done to see the factors affecting catchup growth (CUG) of IUGR babies during first year.

Methods: The study was done in 120 SGA babies for a period of 18 months from October 2013 to March 2015. Antenatal, postnatal factors and anthropometry at 1st, 2nd, 3rd, 6th, 9th and 12 months were noted and analysed.

Results: 78.3% babies showed CUG with in the first year. Preterm IUGR infants showed better CUG than full term. Asymmetric IUGR infants showed better CUG than symmetric. Teenage pregnancy, hypertensive disorders, multiple pregnancies, cardiac disease, anemia, type of IUGR, NICU stay, type of feeding, socioeconomic status, mother age, mother height, mother hemoglobin, gestational age, multiple gestation, birth weight, birth length, head circumference at birth all influenced CUG.

Conclusions: Teenage pregnancies should be avoided. In SGA babies of pregnancy induced hypertension and preeclampsia, failure in CUG occurred more, these babies need to be followed in high risk clinics. SGA infants of mothers with low haemoglobin failed to show CUG, so antenatal nutrition improvement of mother should be done. Breastfed babies had higher CUG rates than formula fed babies, so exclusive breastfeeding should be promoted.
