D and PA+D  interventions had larger effects on glucose reduction  than PA alone .
Lifestyle  interventions significantly improved FPG , HbA1c , FI , HOMA-IR , and bodyweight among adults without IGT or diabetes , and might reduce progression of hyperglycemia to type 2 diabetes mellitus
This study systematic ally assessed the effectiveness of lifestyle interventions on glycemic indicators among adults ( ⩾18years ) without IGT or diabetes .
Short and long-term adherence to swimming and walking programs in older women--the Sedentary Women Exercise Adherence Trial (SWEAT 2).
OBJECTIVE To examine in previously sedentary older women the effects of exercise mode and a behavioural intervention on short and long-term retention and adherence . METHODS Healthy , sedentary women aged 50 - 70 years ( N=116 ) were r and omly assigned to a supervised 6-month swimming or walking program 3 sessions a week . They were further r and omised to usual care or a behavioural intervention . The same program was further continued unsupervised for 6 months . We assessed retention , adherence , stage of exercise behaviour and changes in fitness . RESULTS One hundred women ( 86 % ) completed 6 months and 86 ( 74 % ) continued for 12 months . Retention rates were similar for both exercise modes at 6 and 12 months . Adherence to swimming or walking was similar after 6 months ( 76.3 ( 95 % CI : 69.5 , 83.1)% vs. 74.3 ( 67.7 , 80.9)% ) and 12 months ( 65.8 ( 57.9 , 73.8)% vs. 62.2 ( 54.6 , 70.0)% ) . The behavioural intervention did not enhance retention or adherence . Fitness improved for both exercise modes after 6 months and was maintained at 12 months . CONCLUSIONS Either swimming or walking programs initiated with careful supervision over 6 months result ed in similar high retention and adherence rates by highly motivated older women over 12 months . Behavioural intervention in this setting did not improve these rates further
