Summary

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.

Interventions

BEHAVIORAL

Immediate Automated Push Notifications

Automated weekly push notifications delivered via LINE Official Account from week 1 through week 24. Each week's push notification included health education content covering topics such as BMI measurement reminders, dietary guidance, exercise guidance, obesity comorbidity awareness, and healthy weight clinic introduction. Content was designed based on the Health Belief Model constructs (perceived susceptibility, severity, benefits, barriers, cues to action, self-efficacy) and Nudge theory strategies (reminders, imagery, simplification, rewards, defaults, social norms). The 12-week content cycle repeated in weeks 13-24.

BEHAVIORAL

Delayed Automated Push Notifications

No automated push notifications during weeks 1-12. Starting from week 13, participants received the same automated weekly push notifications as the experimental group through week 24 (identical content and delivery schedule). During weeks 1-12, the platform content was available for self-directed access but no proactive notifications were sent.
