Background: type 2 diabetes is becoming increasingly prevalent worldwide at an alarming rate. Physical activity and adequate dietary patterns are cornerstones for the treatment and prevention of diabetes. Lifestyle intervention programs can be effective, but their application to the elderly needs further study. methods: overall, 43 individuals with diagnosed type 2 diabetes were assigned to control (12 men, 12 women; age 68.9 ± 11.3, range 46- 84 years) or intervention (6 men 13 women; age 69.5 ± 8.9, range 52-81 years) groups based on their own choice. The intervention group received a lifestyle program including physical activity classes and dietary counseling for a 9 month period. The control group received the usual care. Improvement in physical activity and dietary patterns was assessed as well as changes in biological (weight, body composition, blood pressure, lipid profile, hba1c, glycemia), fitness (strength, aerobic endurance, flexibility, agility), psychological (profile of mood states) and economic variables (individual and state cost of medications). results: participants in the intervention group tended to increase their overall physical activity (p=0.020) and to adopt better dietary patterns (p=0.050). However changes in lifestyle were mild: changes in overall physical activity outside the program were non-significant and no significant changes were found in the percentage of compliers with the dietary recommendations for the portuguese population. Significant changes were found in lower limb strength (p=0.014), upper limb strength (p=0.001), aerobic endurance (p=0.001) and upper limb flexibility (p=0.040). Conversely no significant changes were found for body composition, blood pressure, lipid profile or glycemic control. The profile of mood states showed a significant decrease in the fatigue-inertia factor (p=0.002). The cost of medication increased substantially for the state (p=0.028) but not for individuals. conclusions: the program achieved moderate success in relation to behaviour change, but not enough to have a significant impact on most clinical and biological variables. Fitness was improved and perceived fatigue reduced. Our results suggest that in order to be more effective, intervention should begin as early as possible, as its implementation among elderly subjects is difficult. This would lead to a larger response to the program and to a more intense physical activity intervention.
