Study Details

Study Description

Brief Summary

Obesity in children is a serious disease that is associated with increased mortality and decreased life expectancy. A simple tool used to assist in controlling portions (and therefore calorie intake) at mealtime would be of benefit in promoting weight maintenance and/or loss. The purpose of this study is to assess the efficacy of a family intervention using a portion control tool to help control weight in obese children. The investigators hypothesize that the use of portion control tools by the parents and child will result in a greater decrease in the child's BMI over a 6 month period compared with the control group.

Detailed Description

This study is a randomized controlled trial designed to assess the efficacy of a portion control tool to help improve body mass index in obese children over a 6 months period. This study will also assess whether this weight control strategy results in improvement of blood pressure, waist circumference, and biomarkers of obesity including plasma visfatin, adiponectin, fasting lipid profile and apolipoprotein B, liver function tests and fasting insulin and glucose. Both the intervention and the control group will receive a one hour session of standard dietary counseling from a registered dietician at baseline regarding healthy eating habits, appropriate portion sizes and the Canada Food Guide. The duration of this study will be 6 months. Baseline measurements will be taken at the initial visit and again at 3 months and 6 months. Each participants' height and weight will be measured, and BMI will be calculated. Waist circumference and blood pressure will also be measured. A blood sample will be drawn at baseline and 6 months for a fasting lipid profile, fasting insulin, and glucose levels. Measurement of plasma visfatin and adiponectin levels using ELISA will be carried out.
