Task: Intent Identification
Input (English): To establish the determinants of weight, length and head circumference changes during their initial hospitalization in very-low-birth-weight preterm infants.', "A prospective cohort study was performed. Weight z-score and percentage of target dietary intakes (TDIs) were prospectively determined daily during the first 5 weeks of life in a group of preterm infants (n = 111, birth weight <1,500 g, gestational age <34 weeks). Weight, length and head circumference at 36 weeks' postmenstrual age (PMA) were recorded. A mixed effects regression model was used to evaluate changes in weight z-score during the first 5 weeks of life. Simple Pearson correlations and stepwise logistic regression were used to determine the relationship between fetal growth, illness severity, nutritional intake and growth at 36 weeks' PMA.", "Weight z-score decreased significantly in all infants during the first 5 weeks of life from -0.92 ± 0.66 at birth to -1.89 ± 0.65 at 5 weeks. The variation of weight z-score during the first 5 weeks of life was influenced by weight z-score at birth, energy and protein intakes and gestational age. Mean energy and protein intakes were 95.5 and 86.4% of TDIs. Weight z-score fell to -2.05 ± 0.64 at 36 weeks' PMA. Birth weight z-score was significantly correlated with weight z-score at 36 weeks (R2 = 0.71; p < 0.001). Severity of illness influenced the weight z-score at 36 weeks.
