Resumo

© 2024 Lançoni et al.Purpose: To analyze leptin levels in placental tissue and premature infants undergoing phototherapy and to evaluate the potential for prescribing passive exercise after phototherapy in this population. Patients and Methods: This analytical, longitudinal, prospective cohort study included 108 parturients and their respective premature infants. Variables examined included weight, gestational age, body mass index, sex, serum leptin levels in placental tissue, serum bilirubin levels, and reticulocyte count. Results: When comparing each group to a leptin threshold, statistically significant differences were observed at all evaluated time points for placental leptin levels (p < 0.001). Additionally, reticulocyte count decreased in relation to rebound time (p < 0.004). No correlations were found between leptin/bilirubin levels, leptin/reticulocytes, onset of nutrition, and BMI/leptin levels. Conclusion: The findings regarding leptin levels suggest that prescribing passive exercises to premature infants undergoing phototherapy may be feasible because this intervention did not increase leptin levels.
