['To determine the occurrence of hypoglycemic episodes in very low birth weight preterm infants under total enteral nutrition and identify potential risk factors.', "In this single centre cohort study, we analyzed the patients' charts of preterm infants with a gestational age <32 weeks (n\u2009=\u200998). Infants were analyzed in two groups (group 1: birth weight <1000\u2009g, n\u2009=\u200954; group 2: birth weight 1000-1499\u2009g, n\u2009=\u200944). A total of 3640 pre-feeding blood glucose measurements were screened. Risk factors for the development of hypoglycemia were identified by linear and multiple logistic regression analyses.", 'In group 1, 44% (24 of 54) of infants experienced at least one asymptomatic episode of blood glucose <45\u2009mg/dl (<2.5\u2009mmol/l) as compared with 23% (10 of 44) in group 2. Regression analysis identified low gestational age and high carbohydrate intake as potential risk factors for the development of hypoglycemia.'] Are very low birth weight preterm infants at risk for hypoglycemia once on total enteral nutrition?
