Abstract

Background: About 50 % of LBW occurs in term newborns, which is associated with higher infant mortality rates compared to infants of average birth weight. Analysis of feeding practices in at-risk groups is essential to address malnutrition and stunting in infancy.

Aim: To identify feeding practices and anthropometric classification of nutritional status in a cohort of low-birth-weight term infants.

Methods: Methods: Cohort study. A prospective follow-up of 73 term newborns with low birth weight up to six months of age was performed. Feeding practices and anthropometric classification of nutritional were analysed. Data were processed by univariate analysis and multivariate linear regression.

Results: The most common feeding practice was exclusive breastfeeding. Breast milk substitutes are frequent in this population group. The risk of undernutrition ranged from 2.7 % to 19.2 % and of overweight from 4.1 % to 11.0 % during the first six months of life. Low height-for-age risk was the most frequent anthropometric classification during the follow-up period. Average head circumference was consistent in infants with low birth weight. Gestational risk classification, breastfeeding during the first hour of life, and sex of the newborn were predictors of variations in anthropometric indicators.

Conclusions: Exclusive breastfeeding is the most common feeding practice in the population group studied, but using breast milk substitutes is also prevalent. Low height-for-age is the most frequent anthropometric classification. The weight growth rate seems reasonable, but further studies are needed based on gender differences, analysis of the composition of breast milk, and socio-environmental factors involved in growth.
