Prevalence and associated factors of mother-reported jaundice in newborns.

Objective: Newborns' jaundice is the result of bilirubin accumulation as fetal hemoglobin is metabolized by the immature liver. This study aimed to estimate the prevalence of mother-reported newborn jaundice and associated factors.

Methods: A cross-sectional study was carried out using data from a longitudinal study involving 914 children. The data were reviewed using Poisson regression with a robust estimator in a hierarchical model in which the sociodemographic variables constituted the first level, those related to the conditions of the pregnancy constituted the second level, and those related to the report of jaundice, the third level. Prevalence ratios and their relevant confidence intervals were estimated.

Results: The prevalence of reported jaundice in newborns was 17.9%. The variables late pregnancy, urinary infection during pregnancy, and preterm and post-term birth were independently statistically associated with a higher prevalence of newborn jaundice reports.

Conclusion: We can conclude that mother-reported newborn jaundice was 17.9% associated with maternal and birth aspects.
