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 .
A lifestyle program for treated hypertensives improved health-related behaviors and cardiovascular risk factors, a randomized controlled trial.
OBJECTIVE To assess effects of a cognitively based program on health-related behaviors and cardiovascular risk factors in overweight drug-treated hypertensives . STUDY DESIGN AND SETTING In a clinical trials center , volunteers , recruited by advertisement , were r and omized to usual care ( N=118 ) or to a 4-month program ( N=123 ) incorporating weight loss ; a low-sodium diet , high in fruit , vegetables , and fish ; and increased physical activity .  Diet , physical activity , weight , blood lipids , glucose , and insulin were measured at 4 and 16 months . RESULTS Ninety-eight usual care and 106 program participants completed the 4-month assessment ; 90 and 102 , respectively , completed follow-up . Using intention-to-treat analysis , relative to usual care , net changes with the program at 4 months were as follows : dietary fat ( -2.6 % energy ; P<0.001 ) ; sodium ( -290mg/d ; P=0.004 ) ; energy ( -313mJ/d ; P=0.005 ) ; fish ( + 2.1 serves/wk ; P<0.001 ) ; vegetables ( + 3.0 serves/wk ; P<0.001 ) ; physical activity ( + 37min/wk ; P=0.004 ) ; weight ( -2.8 kg ; P<0.001 ) ; waist girth ( -3.1 cm ; P<0.001 ) ; total cholesterol ( -0.2mmol/L ; P=0.017 ) ; and triacylglycerols ( -0.12mmol/L ; P=0.002 ) . One year later , net changes included dietary fat ( -2.2 % energy ; P<0.001 ) ; sodium ( -150mg/d ; P=0.029 ) ; fish ( + 2.0 serves/wk ; P<0.001 ) ; vegetables ( + 4.3 serves/wk ; P<0.001 ) ; weight ( -2.5 kg ; P=0.001 ) ; waist girth ( -3.1 cm ; P<0.001 ) ; high-density lipoprotein cholesterol ( + 0.03mmol/L ; P=0.031 ) . CONCLUSION Improvements in behaviors and risk factors , several maintained long term , suggest the potential for long-term benefits in hypertensives
