Frequency Needed for School-based Obesity Intervention
7. januar 2019 oppdatert av: Craig A Johnston, University of Houston
Frequency of Intervention Needed to Improve Weight Outcomes of Mexican-American Adolescents With Overweight or Obesity
This randomized controlled trial compared changes in Mexican-American, adolescent standardized body mass index (zBMI) from a school-based obesity intervention given zero, one, three, or five days a week.

Detaljert beskrivelse
Efficacious school-based interventions have been intensive making it difficult for interventions to be scaled.
The more components there are to an intervention, typically the better the results.
Instead of decreasing intensity via the removal of intervention components, this randomized controlled trial aimed to compare changes in Mexican-American adolescent standardized body mass index (zBMI) based on the number of days per week they received a multi-component intervention.
Mexican-American middle school students (n=203) with overweight or obesity were recruited from an independent school district in Houston.
Students were randomized to receive an obesity intervention with established efficacy zero (control), one, three, or five days/week.
In each condition, 80% of intervention time was allocated to physical activity and 20% to nutrition.
Directly measured height and weight were used to calculate zBMI.

Eksperimentell: 1 day
received the intervention 1 day/week

The intervention consisted of nutrition lessons based on the traffic light diet, circuit-based physical activity, behavior modification techniques (token economy system, goal setting, self-monitoring), and parental involvement (materials sent home and monthly parent meetings).
80% of time was spent on physical activity and 20% was spent on nutrition.
Behavior modification was incorporated into both physical activity and nutrition time.
Specifically, instruction and activity time during PE class lasted approximately 40 minutes.
