BACKGROUND: Mothers’ knowledge of neonatal jaundice (NNJ) is grossly deficient or inaccurate, which may adversely affect the actions of mothers in the recognition of NNJ and cause a delay in seeking medical attention.

MATERIAL AND METHODS: A total of 1036 primiparas were separated randomly into the intervention group and the control group, with 518 primiparas in each group.

RESULTS: All (100%) mothers in the intervention group understood that NNJ is a yellow discoloration of the skin and sclera; 94.19% of them considered that NNJ is a common problem in newborns; 82.80% and 95.27% replied that jaundice appearing within the first 36 hours and lasting more than 2 weeks usually indicates pathological NNJ; 96.34%, 80.86%, and 90.32% realized that premature newborns, low birth weight, and perinatal asphyxia, respectively, are more likely to be accompanied by NNJ; 97.41%, 78.71%, and 64.95% knew that maternal-fetal blood group incompatibility, infection, and glucose-6-phosphate dehydrogenase deficiency, respectively, are the common inducements to NNJ; 94.84% could associate NNJ with brain damage; 92.26%, 93.12%, and 74.62% agreed that phototherapy, strengthen feeding, and exchange blood transfusion, respectively, can greatly relieve NNJ. However, some respondents in the control group responded in other ways, such as stopping breastfeeding (9.19%), placing newborns in sunlight (10.24%) and traditional Chinese medicine (10.24%), which was significantly higher than that of the intervention group. There was also a significant delay for respondents in the control group in consulting a pediatrician, and 6.30% of them did not seek medical help until after the interview.

CONCLUSIONS: Prenatal training could significantly improve new mothers’ understanding of NNJ.
