Brief summary

Physical activity levels of Australia’s ageing population are declining, while their rates of overweight and obesity are increasing. Physical activity and a healthy diet are recognised as important in maintaining a healthy weight and preventing chronic disease. The retirement village provides a unique setting to access and engage with this older target group, to test the effectiveness of strategies to increase levels of physical activity, improve nutrition and maintain a healthy weight. This large scale RCT will evaluate a physical activity, nutrition and healthy weight management intervention for adults aged 60-75 years residing in retirement villages that will ultimately reduce chronic disease (e.g. diabetes, cardiovascular disease, and some cancers). By the end of the intervention we anticipate that there will be a significant improvement in physical activity (time/intensity) and dietary behaviours (10% reduction in dietary fat; 10%fibre intake; 10% increase in fruit/vegetables consumption), and body composition of the intervention group participants, compared to the control group participants.

Interventions

Inclusion criteria

A total of 400 participants will be recruited from 20 retirement villages (intervention group villages n=10: control group villages n=10). Participants will be required to be aged 60 to 75 years; insufficiently active (not achieving the recommended level of 150 minutes of moderate physical activity per week); on no special diet; not involved in another special physical activity program, and able to participate in a low-stress physical activity program with minimal risk to overall health and wellbeing. Couples may enter the control or intervention group together but cannot be allocated to separate groups (risk of contamination).The program is for the age group 60-75 y. The prevalence of underweight (<18.5 BMI) is low in this age group. However, at risk participants identified will be referred to their GP for follow- up and excluded from the study.

Exclusion criteria

A Physical Activity Readiness (PAR_Q)questionnaire and a medical clearance form will be completed on enrollment. This will allow for those deemed high risk to be eliminated from the study.
