Analysis of Body Composition of Premature Low Birth Weight Infants with Pathological Jaundice
Objective To investigate the difference of body composition in premature low birth weight infants with pathological jaundice.Methods A total of 51 premature low birth weight infants born in Liuzhou Maternity and Child Healthcare Hospital from August 2021 to February 2022 were included.According to whether they were complicated with pathological jaundice,they were divided into jaundice group and control group.The body composition of infants was collected on the 1st to 7th day after birth,including fat mass,lean body mass,hydration status,total body water and nutritional index.The difference of body composition between the two groups was analyzed by bioelectrical impedance.Results There were 13 infants with pathological jaundice on the 2nd day after birth and 38 infants without pathological jaundice;there were significant differences in phase angle,fat and total water content between the jaundice group and the control group(P＜0.05).On the 3rd day after birth,there were 16 infants with pathological jaundice and 22 infants without pathological jaundice;there were significant differences in phase angle and total body water content between the jaundice group and the control group(P＜0.05).On the 4th day after birth,there were 7 infants with pathological jaundice and 15 infants without pathological jaundice;there were significant differences in phase angle and total body water content between the jaundice group and the control group(P＜0.05).On the 5th day after birth,there were 8 infants with pathological jaundice and 7 infants without pathological jaundice;there were significant differences in the phase angle and total body water content between the jaundice group and the control group(P＜0.05);there were no significant differences in lean meat,nutritional index,predictive index and musculoskeletal group content between the two groups on the 1st to 7th day after birth(P＞0.05).Conclusion The phase angle measurement value and total body water content of premature low birth weight infants with pathological jaundice are lower than those of infants without pathological jaundice,suggesting that the lower the total water content,the lower the phase angle detection value,and the greater the possibility of pathological jaundice in infants.However,due to the limitations of the study,whether phase angle and total body water content can be used to predict the risk of pathological jaundice in preterm low birth weight infants needs further study.
