BACKGROUND
Unintentional injuries are a major public health problem to children worldwide. With the widespread use of smartphones in China, social networking mobile applications, such as WeChat, are potential ways to implement parent-based interventions.
OBJECTIVE
This study aimed to evaluate the effectiveness of WeChat group-based parental intervention programs in preventing unintentional injuries in children aged 0–3 years in China.
METHODS
We conducted a randomized controlled trial from March 2019 to March 2020. A total of 365 parents of children aged 0–3 years in Shanghai were randomly allocated to intervention and control groups, and 276 participants completed the follow-up. We used generalized estimation equations to assess intervention effectiveness at baseline and after one year. Outcome measures included children’s unintentional injury incidences, parents’ knowledge, attitudes, and behaviors.
RESULTS
During the one year follow-up, unintentional injury incidences increased from 9.00% to 11.70% in the intervention group and from 9.90% to 22.90% in the control group. The changes did not differ between the groups (odds ratio [OR] 0.67, 95% confidence interval [CI] 0.13-3.48). Changes in the parents’ attitudes toward injury attribution (b 0.10, 95% CI 0.09-0.21) and preventability (b 0.16, 95% CI 0.01-0.33) did not differ between the two groups. Changes in parents’ attitudes toward responsibility in the intervention group were greater than those in the control group (b 0.33, 95% CI 0.15, 0.51). Changes in parents' daily supervision behavior in the intervention group was greater than those in the control group (b 0.43, 95% CI 0.02-0.84), and changes in behaviors of preventing specific injuries were significantly different between the groups (b 1.60, 95% CI 1.05-2.16).
CONCLUSIONS
Although WeChat group-based parental intervention cannot directly reduce the occurrence of children’s unintentional injuries, it can improve parents’ knowledge, attitudes, and behaviors pertaining to prevention of unintentional injuries.
