摘要:Purpose: The purpose of this study is to explore the dangers experienced by mothers and families of infants aged 3 - 4 months in Japan during ablution and bathing. Method: We distributed an anonymous, self-reported questionnaire at infants’ 3 - 4-month health checkup, which was collected via postal service. 170 valid responses were received and formed our sample data. Descriptive statistical analysis was performed for each category surveyed. Inferential statistics were used to compare the dangerous incidents experienced with regard to differences between primi/multipara and the presence/absence of guidance concerning such incidents. This study was approved by the research ethics committees of the affiliated university. Results: 60.0% of mothers and families experienced dangers while washing their infant in a baby tub or similar apparatus (ablution), and 64.9% did while bathing their infant in the normal bath. For ablution, the most common dangers were, in order, nearly dropping the infant in the water and nearly getting soap suds in the mouth. For bathing, these were nearly getting soap suds in the mouth, near submersion of the face, and nearly dropping the infant in the water. The percentage of mothers and families who did not receive instruction regarding potential dangers and their prevention was 55.9% for ablution and 81.8% for bathing. Conclusion: This study revealed the dangers experienced by mothers and families of infants aged 3 - 4 months in Japan during ablution and bathing. Further consideration into the prevention of these dangers is necessary.
