The Outcomes and Complications Stream has COMPLETED its work, however information is retained here on this site for reference.

How will obesity affect the physical and psychological well-being of children in coming decades? What effects will childhood obesity have on life expectancy, the national economy, and our society? 1

The Outcomes & Complications stream wants to promote research across Australasia that can rapidly address these vital questions. We aim to:

1. publicise Australasian longitudinal obesity studies via the ACAORN website

2. support data pooling from Australasian longitudinal studies to address priority research questions

3. promote uniform definitions of core outcome and complication constructs

4. Work with other networks 3 and professional groups across the laboratory-clinical-community-population research spectrum to achieve the above aims.

Stream members have jointly prioritized the following questions:

Within overweight/obese groups:

1. What factors predict relative BMI reduction over time?

2. What factors predict comorbidities?

3. What is the relationship between sleep parameters (quantity and quality) and change in adiposity over time?

Within populations2:

4. What are the modifiable environmental risk/protective factors for childhood obesity, and at what ages do they start making their impact felt?

5. What parental and family factors influence the future development of obesity in the child?

6. What are the longitudinal relationships between the development of obesity and physical, social and mental health?

7. What prenatal and early childhood patterns of growth and nutrition predispose to later obesity?

8. What prenatal and early childhood patterns of growth and nutrition predispose to later obesity?

9. Secular trends in incidence of overweight/obesity during the period 1970 – 2010
