Effectiveness of Parent-based Electronic Health (eHealth) Intervention on Preschoolers' Physical Activity, Dietary Behaviors, and Sleep Problems

Summary

Background: Preschoolers' lifestyles have become physically inactive and sedentary, their eating habits unhealthy, and their sleep routines increasingly disturbed. Parental involvement appears to be crucial to combat unhealthy lifestyle of preschoolers. Because of recognized barriers of traditional face-to-face interventions (such as time commitment for parents), easy access and lower costs make electronic health (eHealth) interventions appealing. Previous studies that examined the effectiveness of parent-based eHealth on preschooler's (physical activity) PA, dietary behaviors (DB), and sleep have either emphasized on one variable or failed to balance the dosage of PA, diet, and sleep modules or consider the intervention sequence during the intervention period and there is an acknowledged gap in parent-based eHealth interventions which target preschoolers raised in Chinese cultural contexts.

Objective: This study aims to investigate the effectiveness of parent-based eHealth intervention on Chinese preschoolers' PA, DB, and sleep problems.

Methods: This two-arm parallel randomized controlled trial comprises a 12-week intervention with a 12-week follow-up. 206 parent-child dyads will be randomized to either eHealth intervention group or control group. Participants allocated to the eHealth intervention will receive 12 interactive modules on PA, DB, and sleep, with each module rot on a weekly basis to reduce the sequence effect on variable outcomes. The intervention is grounded upon Social Cognitive Theory and will be delivered through social media, where parents can obtain valid and updated educational information, social rapport, and interact with other group members and facilitators. Participants in the control group will receive weekly brochures on PA, DB, and sleep recommendations from the kindergarten teachers, but they will not receive any interactive components. Data will be collected at baseline, 3 months, and 6 months. The primary outcome will be the preschooler's physical activity. The secondary outcomes will be the preschooler's dietary behaviors, preschooler's sleep duration, and preschooler's sleep problems, parent's PA, parenting style, and parental feeding style.

Significance of this study: The parent-based eHealth intervention has potential to overcome the aforementioned barriers of face-to-face interventions, which will offer a novel approach for promoting healthy lifestyle of preschoolers. If found to be efficacious, the prevalence of unhealthy lifestyles among preschoolers may be alleviated at a low cost, which not only has a positive influence on the health of the individual and the well-being of the family but also reduces the financial pressure on society to treat diseases caused by poor lifestyle habits.

Interventions

BEHAVIORAL

parent-based Electronic Health intervention

The eHealth intervention comprises 12 modules on three interaction modules related to physical activity, dietary behavior, and sleep. The intervention groups will be invited to a "WeChat group". A 3-minute video (made on the TikTok APP) will be sent to each WeChat group. Based upon the social media studies recommendation, five to nine members in a group will produce the desirable group interactive effect. Therefore, the present study allocates eight parents to one WeChat group. In total, there will be 26 groups (206 parents) according to the sample size calculation. Consistent with Social Cognitive THeory, the content of each module will follow the four steps: 1. Attention (Read educational material and watch TikTok/Douyin video (less than 3 minutes). 2.Retention (parental interaction). 3.Reproduction (Set goals and conduct behaviors). 4.Motivation (feedback and making changes).
