Study on the Tailored Intervention Strategy of Childhood Obesity Based on Monitoring Physical Activities and Dietary Behaviors

Overview

The project aims at developing the tailored intervention strategy of childhood obesity based on monitoring physical activities with accelerometer and dietary behaviors using diary. It probably raise the passion of obese children to control weight, form healthy life style, be effective in sustaining weight loss and early prevent adulthood diseases.

Detailed Description

The overweight and obese primary school students from 1-5 grades will be recruited according to "Body Mass Index Reference for Screening Overweight and Obesity in Chinese School-age Children". The participants with will be allocated with schools as the unit to four groups: tailored intervention based on monitoring physical activity and dietary behaviors, exercise intervention group based on the Happy 10 program, nutrition education intervention group. The three intervention groups received the designed interventions for the duration of 1 year. Before and after the intervention, we will carry out a questionnaire survey, a physical measurement, a fitness test, and a metabolic markers detection

Interventions

  • Behavioral: Monitoring and Tailored prescription
  • Behavioral: Happy 10 program
  • Behavioral: Specified nutrition education
  • Behavioral: General Health Education

Arms, Groups and Cohorts

  • Experimental: Tailored intervention group
    • For the monitoring session, physical activity was assessed by accelerometer and dietary was assessed by diary. Based on the monitoring information, the individual tailored prescription, including the normative feedback and process feedback, were formed and delivered to children and parents. Children were encouraged to modify the behaviors according to the prescription. Then, next monitoring circle was followed. In total, 7 monitoring round were completed.
  • Experimental: Happy 10 exercise group
    • All the schools participating in this group were encouraged to take two Happy 10 sessions on each school day.
  • Experimental: Nutrition education group
    • The nutrition intervention was mainly conducted based on the nutrition knowledge through health education lectures given by researchers. The lectures were given for eight times to students and twice to parents. Each lecture session lasted no less than 40 min.
  • No Intervention: Control group
    • Receive no intervention
