Exercise Consultation in Obese Youth

Study Overview
=================
Brief Summary
-----------------
Exercise consultation, an intervention approach based on the transtheoretical model has been successful in promoting physical activity (PA) among adults. It is unknown whether this approach would be efficacious with youth. The purpose of this pilot study was to assess whether exercise consultation would increase PA levels and improve anthropometric measures and metabolic markers in obese adolescents.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Placebo Comparator: 1<br> | Behavioral: review of Canada's Physical Activity Guide for Youth<br>* The contents of the exercise booklet was reviewed with each participant of the control group by the research fellow. Health Canada's Canada's Physical Activity Guide for Youth was used for the exercise booklet<br>|
| Experimental: 2<br> | Behavioral: Exercise consultation<br>* The exercise consultation consisted of a one-to-one discussion designed to educate the participant, strengthen his/her motivation and develop realistic goals and strategies to promote physical activity based on the patient's stage of change. The consultation was based upon the standardized protocol previously published by Loughlan and Mutrie. The Consultation Guidelines describe the 5 steps involved in an exercise consultation, including: 1) discussing current & past activities; 2) reviewing the pros & cons of exercising; 3) discussing the barriers to exercising and strategies for overcoming them; 4) determining the social support available to the patient; and finally, 5) setting realistic, attainable short term and long term goals to enhance physical activity.<br>|
