Community-based weight management of overweight and obese adolescents: The Loozit trial

The Loozit Trial logo

Formal study name:
Community-based weight management of overweight and obese adolescents: a randomised controlled trial of extended therapeutic contact vs. recommended care.
RCT registry and number: ANZCTR; 12606000175572
Web link: http://www.chw.edu.au/kids/loozit

The aim of the Loozit RCT is to determine the effect of additional therapeutic contact over a 2 year period on a community-based weight management group program for overweight and obese adolescents aged 13-16 years. The additional therapeutic contact, via phone coaching, e-mail and SMS messages, is designed to give the adolescents extra support and guidance to empower them to make and maintain healthy lifestyle changes.

Formal study name:
Randomised controlled trial of a brief GP intervention to reduce overweight in Victorian primary school children.
RCT registry and number: ISRCTN; 52511065
Web link: http://www.rch.org.au/ccch/research.cfm?doc_id=10643

Preventing childhood obesity is an important goal - but many thousands of Australian children are already overweight or obese. What role can family doctors play in managing childhood obesity? LEAP addressed this question in a large randomised trial. Family doctors learned new techniques that aimed to help overweight Victorian children aged 5 to 10 years old develop healthier lifestyles and weight. Results are due by 2009.

Formal study name:
Parent-led family-focused treatment program for overweight 5-9 year olds: the PEACHTM RCT.
RCT registry and number: ANZCTR; 00001104

The aim of this study was to compare the effectiveness in moderately obese prepubertal children of two 6-month treatment interventions delivered to parents only: parenting skills training plus healthy lifestyle education versus healthy lifestyle education alone.

HopSCOTCH

Formal study name:
Shared Care Overweight Trial in Children
RCT registry and number: ANZCTN; 12608000055303
Web link: http://www.rch.org.au/ccch/hopscotch

Most of the 200,000 overweight or obese children in Australia aren't currently receiving any care for their obesity. This could change dramatically if general practitioners were supported to work effectively with specialist services. HopSCOTCH is a randomised trial of a shared-care approach to managing obesity in 3 to 9 year olds. GPs will share care with a specialist multidisciplinary team, supported by state-of-the-art shared software. 12 month outcomes include healthier growth patterns and an economic evaluation.

The "Eat Smart" study

Formal study name:
A randomised controlled trial of a reduced carbohydrate diet versus a low fat diet for the treatment of childhood obesity: The Eat Smart Study.
RCT registry and number: ISRCTN; 49438757; http://www.controlled-trials.com/ISRCTN49438757
Web link: http://www2.som.uq.edu.au/som/Research/ResearchCentres/cnrc/Pages/Obesity.aspx

This study is a 12 month study examining the relative efficacy of a low fat versus a reduced carbohydrate diet on body composition change in a randomised controlled trial. It incorporates a novel psychological preparedness phase, using a group based approach, to equipe adolescents with skills so they can engage in lifestyle change.

RESIST

Formal study name:
Dietary intervention for adolescents with prediabetes
RCT registry and number: ANZCTR; ACTRN12608000416392

A 12 month randomised control trial investigating the effects of dietary protein on insulin sensitivity in overweight adolescents with clinical insulin resistance and/or pre-diabetes. The study includes dietary intervention, a gym based exercise program and treatment with metformin (at no cost to participants). The study is multicentred and includes the Children’s Hospital at Westmead, RPAH and Campbelltown Hospital

Along with the rise in prevalence of overweight and obesity there has been a significant increase in the number of adolescents with clinical signs of insulin resistance and/or prediabetes. The aim of this study is to determine the efficacy of two different dietary interventions (a moderate protein diet and a high carbohydrate diet) on insulin sensitivity, in adolescents with clinical insulin resistance and/or prediabetes. This trial will provide definitive data on the effective management of clinical insulin resistance and prediabetes in this age group.

HICKUPS is a community-based randomised controlled trial that aims to evaluate and compare in overweight children the effectiveness of the following interventions: 1) a child-centred physical activity skill development program; 2) a parent-centred dietary modification program; and 3) a combination of 1 and 2. The following outcomes are being measured at baseline, 6-, 12-, and 24-months: adiposity, metabolic profile, physical activity, sedentariness, food habits and eating behaviours, movement skills, self-esteem, quality of life and an activity of daily living. Overwhelming, parents have enjoyed the program and found it helpful.

Wollongong Sport

Formal study name:
Wollongong Sport
RCT registry and number: Feasibility trial - the RCT will be registered in 2009.

Based on the successful Stanford Sport program in the US, the aim of this project is to prevent unhealthy weight gain, increase cardio-respiratory fitness, objectively measured physical activity, perceived competence (self-esteem) and health-related quality of life among overweight or at-risk-of-overweight girls ages 8-to 11-years.

WASPA

Formal study name:
Western Sydney Adolescent Sport and Physical Activity Program (WASPA)
RCT registry and number: ACTRN 12609000134224

In 2006, we successfully conducted a feasibility trial of the WASPA program among 16 overweight and obese adolescents. The aim of this proposed project is to build on the promising results from our feasibility trial and conduct a pilot randomised controlled trial to determine the feasibility, acceptability, and potential efficacy of the WASPA program in preventing unhealthy weight gain among overweight and obese adolescents. 40 adolescents from neighbourhoods with a high proportion of families from non-English-speaking backgrounds will be recruited and randomly allocated to either the WASPA program or an active control intervention. The main outcome measures will be adiposity, cardio respiratory fitness, physical activity, eating behaviours, quality-of-life, and implementation and process measures.

An intervention to reduce sedentary behaviour, promote physical activity and improve children's health

Formal study name:
An intervention to reduce sedentary behaviour, promote physical activity and improve children's health
RCT registry and number: in process of registration

Sedentary behaviours and physical inactivity play a major role in the rising prevalence of obesity among children in Australia. This intervention study will take place in the school and family settings which play a critical role in shaping children's health behaviours. The objective is to determine whether a 2-year behavioural intervention reduces sedentary behaviour and promotes physical activity and results in improved health among 8-9 year old children.
