This study evaluated the effectiveness of a LINE Official Account (a mobile messaging platform) as a digital health education tool to enhance parental engagement with childhood obesity-related health literacy content. Parents of school-aged children (grades 1, 4, and 7) identified as obese through school health screenings in Taipei, Taiwan, who declined face-to-face clinic participation, were invited to join the LINE Official Account platform. Participants were allocated to either an immediate push notification group (receiving automated educational messages for 24 weeks from enrollment) or a delayed push notification group (receiving no push notifications for the first 12 weeks, followed by 12 weeks of push notifications). The study compared parental engagement behaviors between the two groups, including the proportion of users clicking interactive educational content and the click frequency per user, to determine whether the timing of push notification initiation affects parental engagement with digital health education content related to childhood obesity.
