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 .
Exercise on prescription for women aged 40-74 recruited through primary care: two year randomised controlled trial
Objective To assess the effectiveness of a primary care based programme of exercise on prescription among relatively inactive women over a two year period . Design R and omised controlled trial . Setting 17 primary care practice s in Wellington , New Zeal and Participants 1089 women aged 40 - 74 not undertaking 30 minutes of moderate intensity physical activity on at least five days of the week  Intervention Brief physical activity intervention led by nurse with six month follow-up visit and monthly telephone support over nine months . Main outcome measure Physical activity assessed at baseline and 12 and 24 months . Secondary outcomes were quality of life ( SF-36 ) , weight , waist circumference , blood pressure , concentrations of fasting serum lipids , glycated haemoglobin ( HbA1c ) , glucose , insulin , and physical fitness . Results Mean age was 58.9 ( SD 7 ) years . Trial retention rates were 93 % and 89 % at 12 and 24 months , respectively . At baseline , 10 % of intervention participants and 11 % of control participants were achieving 150 minutes of at least moderate intensity physical activity a week . At 12 months rates increased to 43 % and 30 % and at 24 months to 39.3 % and 32.8 % ( P<0.001 ) , respectively . SF-36 physical functioning ( P=0.03 ) and mental health ( P<0.05 ) scores improved more in intervention compared with control participants , but role physical scores were significantly lower ( P<0.01 ) . There were no significant differences in clinical outcomes . More falls ( P<0.001 ) and injuries ( P=0.03 ) were recorded in the intervention group . Conclusions This programme of exercise on prescription increased physical activity and quality of life over two years , although falls and injuries also increased . This finding supports the use of exercise on prescription programmes as part of population strategies to reduce physical inactivity .
