Brief summary

The aim of this study is to determine the effect of extended therapeutic contact over a 2 year period on a community-based weight management group program in overweight and obese young people aged 13-16 years. The additional therapeutic contact, via phone coaching, e-mail and SMS messages, is designed to give each young person the extra support and guidance to empower them to make and maintain healthy lifestyle changes. 168 young people will be randomised into either the group program, or the group program plus extended therapeutic contact. They will be followed up for 2 years to assess the effect of the program on a variety of health outcomes including weight, self-esteem and metabolic health. Adolescents’ height, weight and waist circumference will be measured at baseline, 12 months and 24 months by contract staff who are blinded to treatment allocation. In addition, adolescents will be asked not to reveal their treatment allocation to staff who perform the measurements. Of course, it will not be possible for the adolescents to be blinded to treatment allocation. If effective, we expect the following outcomes: 1) A reduction in levels of overweight and obesity in young people aged 13-16 years 2) The adoption and maintenance of healthy lifestyle behaviours in that segment of the population which has most to gain over a lifetime - overweight and obese young people 3) A novel, replicable, feasible, cost-effective community-based approach to overweight and obesity in young people tailored to the Australian health care system

Interventions

Intervention (G+E): current recommended treatment for adolescent overweight & obesity + extended therapeutic contact. Extended therapeutic contact will include a combination of telephone coaching, emails and short messaging service (SMS) text messaging Current recommended treatment: group program weekly initially for 8 weeks followed by one booster group session each term for the next 7 terms. Group program focuses on modification of behaviour, diet and physical activity, and building self-estee
