There was no evidence for a relationship between intervention effectiveness and mode of delivery or number of intervention contacts ; however , interventions which involved individually tailoring with personalized activity goals or provision of information about local opportunities in the environment may be more effective .
Conclusions Interventions in adults aged 55 to 70 years led to long term improvements in physical activity at 12 months ; however , maintenance beyond this is unclear .
Identified physical activity improvements are likely to have substantial health benefits in reducing the risk of age-related illnesses .
Background Retirement represents a major transitional life stage in middle to older age .
Changes in physical activity typically accompany this transition , which has significant consequences for health and well-being .
The aim of this systematic review was to evaluate the evidence for the effect of interventions to promote physical activity in adults aged 55 to 70 years , focusing on studies that reported long-term effectiveness .
Prevention of Type II diabetes in subjects with impaired glucose tolerance: the Diabetes Prevention Study (DPS) in Finland
Study design and 1-year interim report on the feasibility of the lifestyle intervention programme
Aims /hypothesis . The aim of the Diabetes Prevention Study is to assess the efficacy of an intensive diet-exercise programme in preventing or delaying  Type II ( non-insulin-dependent ) diabetes mellitus in subjects with impaired glucose tolerance , to evaluate the effects of the intervention programme on cardiovascular risk factors and to assess the determinants for the progression to diabetes in persons with impaired glucose tolerance . Methods . A total of 523 overweight subjects with impaired glucose tolerance ascertained by two oral glucose tolerance tests were r and omised to either a control or intervention group . The control subjects received general information at the start of the trial about the lifestyle changes necessary to prevent diabetes and about annual follow-up visits . The intervention subjects had seven sessions with a nutritionist during the first year and a visit every 3 months thereafter aim ed at reducing weight , the intake of saturated fat and increasing the intake of dietary fibre . Intervention subjects were also guided individually to increase their physical activity .  Results . During the first year , weight loss in the first 212 study subjects was 4.7 ± 5.5 vs 0.9 ± 4.1 kg in the intervention and control group , respectively ( p < 0.001 ) . The plasma glucose concentrations ( fasting : 5.9 ± 0.7 vs 6.4 ± 0.8 mmol/l , p < 0.001 ; and 2-h 7.8 ± 1.8 vs 8.5 ± 2.3 mmol/l , p < 0.05 ) were significantly lower in the intervention group after the first year of intervention . Favourable changes were also found in blood pressure , serum lipids and anthropometric indices in the intervention group . Conclusion /interpretation . The interim results show the efficacy and feasibility of the lifestyle intervention programme . [ Diabetologia ( 1999 ) 42 : 793–801
