The Impact of Mothers’ Smartphone Use, eHealth Literacy, Maternal Role Performance Confidence, and Online Social Support on Health Promotion Behavior for Infants and Toddlers

Background: This study aimed to identify the factors influencing health promotion behaviors for infants and toddler, focusing on the time spent by mothers using smartphone, eHealth literacy, maternal role performance confidence, and online social support.Methods: This study surveyed 136 women who gave birth to a child in 2023. For this study, recruitment announcements were made on popular parenting websites. Multiple regression analysis was performed to identify the factors affecting health promotion behaviors.Results: The mean age of the participants was 33.8 years, and the mean age of the children was 13.3 months old. Mothers spent 20.2 hours weekly on smartphone to access health information. A total of 86.7% of the respondents indicated that they primarily used the Internet to make health decisions. Factors that influenced health promotion behaviors were role performance confidence (β=0.54, P<0.001), eHealth literacy (β=0.18, P=0.015), online social support (β=0.16, P=0.022), and time spent on smartphone (β=-0.17, P=0.006), with an explanatory power of 51.3% (F=29.43, P<0.001).Conclusions: To improve the health promotion behaviors of mothers for their infants and young children, it is believed that interventions that increase confidence in their roles, online social support, and eHealth literacy are required, and that smartphone screen time should be limited. These baseline data can guide the development of effective intervention programs to improve healthcare for infants and toddlers.
