A Community-Based Lifestyle Intervention Targeting Type II Diabetes Risk Factors in an Australian Aboriginal Population: A Feasibility Study

Abstract

Objectives: To examine the responsiveness of an Aboriginal cohort to a community-based lifestyle intervention targeting risk factors for type II diabetes. Methods: A Pre-test/post-test cohort study conducted in two rural Australian locations: Port Augusta, South Australia and Drouin, Victoria. The cohort consisted of 25 individuals of Aboriginal descent (mean age = 44.4 ± 12.3 yrs, age range = 25-70 yrs, 7 males/18 females). The intervention used was the Complete Health Improvement Program, involving 11 group sessions conducted over a one-month period, which promoted a low-fat plant-based diet and physical activity. The main outcomes measured were changes in body weight, fasting plasma glucose (FPG), lipid profile and blood pressure (BP). Results: Over the 4 week intervention mean body weight decreased by 3.1 kg (95% CI 2.26 to 4.06), a 3.5% reduction from baseline (p 5.5 mmol/L at baseline showed a 23.6% reduction in mean FPG (7.82 mmol/L to 5.97 mmol/L, p=0.005) and a 4.12% reduction in body weight (98.85 kg to 94.78 kg, p Conclusion: This feasibility study showed that a lifestyle intervention promoting a low-fat eating pattern combined with physical activity reduced risk factors associated with type II diabetes in a rural Aboriginal cohort when conducted in their usual living environment. Implications: There is potential for committee-based lifestyle interventions to improve the health risk profile of Aboriginal participants.
