Physical activity and nutrition program for seniors (PANS): protocol of a randomized controlled trial

Background Along with reduced levels of physical activity, older Australian's mean energy consumption has increased. Now over 60% of older Australians are considered overweight or obese. This study aims to confirm if a low-cost, accessible physical activity and nutrition program can improve levels of physical activity and diet of insufficiently active 60-70 year-olds. Methods/Design This 12-month home-based randomised controlled trial (RCT) will consist of a nutrition and physical activity intervention for insufficiently active people aged 60 to 70 years from low to medium socio-economic areas. Six-hundred participants will be recruited from the Australian Federal Electoral Role and randomly assigned to the intervention (n = 300) and control (n = 300) groups. The study is based on the Social Cognitive Theory and Precede-Proceed Model, incorporating voluntary cooperation and self-efficacy. The intervention includes a specially designed booklet that provides participants with information and encourages dietary and physical activity goal setting. The booklet will be supported by an exercise chart, calendar, bi-monthly newsletters, resistance bands and pedometers, along with phone and email contact. Data will be collected over three time points: pre-intervention, immediately post-intervention and 6-months post-study. Discussion This trial will provide valuable information for community-based strategies to improve older adults' physical activity and dietary intake. The project will provide guidelines for appropriate sample recruitment, and the development, implementation and evaluation of a minimal intervention program, as well as information on minimising barriers to participation in similar programs

Recent trends in physical activity in New South Wales. Is the tide of inactivity turning?

Objective: To examine recent trends in sufficient physical activity among New South Wales adults aged 16 years and over. Method: Data were obtained from New South Wales population health surveys conducted in 1998 and from 2002 to 2005. Analyses examined trends in the proportions of adults achieving sufficient physical activity and trends in different modes of activity. Results: The proportion of adults achieving sufficient physical activity was stable between 1998 (47.6%) and 2002 (46.5%), declined in 2003 (44.7%), increased substantially in 2004 (50.5%), and remained steady in 2005 (51.3%). This increase was evident across different population groups. Adults who did any walking were 18 times more likely to be active than those who did no walking. Conclusion: Findings indicate that in recent years physical activity participation has begun to increase, and that this increase occurred across population segments. The increases occurred especially in walking behaviours. Implications: Given the known health benefits of being physically active, continued investment in physical activity promotion policies and programs is necessary to maintain these early gains
