INDIGO Study: physical activity and goal-setting intervention for sedentary older adults at risk of cognitive decline

Project Details

Cognitive decline is common in old age. In Australia 1400 new cases of dementia are diagnosed each week with Alzheimer's Disease being the most common cause. Physical Activity (PA) appears to be one of the strongest factors to delay or prevent cognitive decline. Despite this, physical inactivity has been shown to increase with age. Changing this sedentary behaviour is difficult, and groups with health problems face an even greater challenge. However, it has been reported that motivators such as self-efficacy (confidence to exercise safely), the ability to set individual PA goals and enjoyment of the PA increase adherence.

The INDIGO Study is a single-blind randomised controlled trial based on the CONSORT guidelines. The primary aim of INDIGO is to determine whether a home-based physical activity intervention with individual goal setting and peer mentors can significantly increase PA levels in older adults who do not engage in leisure time physical activity and are at increased risk of developing Alzheimer's disease.
