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 .
Health-related effects of worksite interventions involving physical exercise and reduced workhours.
OBJECTIVES This study examined the health-related effects of two worksite interventions , physical exercise and reduced workhours , on women employed in dentistry . METHODS Six workplaces were r and omized to one of the following three conditions : ( i ) 2.5 hours of weekly , m and atory physical exercise of middle-to-high intensity to be performed during workhours ( N=62 ) , ( ii ) a reduction of full-time weekly workhours from 40 to 37.5 hours ( N=50 ) , and ( iii ) reference . In all , 177 women participated . Biomarkers and self-ratings in question naires were obtained before the intervention ( T ( 1 ) ) , and six ( T ( 2 ) ) and 12 months ( T ( 3 ) ) after the intervention . RESULTS The results showed increased levels of physical activity and exercise in all of the groups , the level of physical exercise being significantly greater in the physical exercise group . Repeated- measures analyses of variance using data from T ( 1 ) and T (3)for biological measures and all three time points for self-ratings produced significant interaction effects for glucose , waist-to-hip ratio , and work ability and clear trends for general symptoms and upper-extremity disorders . Posthoc analyses showed that the results of the health-related measures differed between the interventions , decreased glucose and upper-extremity disorders in the exercise group , and increased high-density lipoprotein and waist-to-hip ratio among those working reduced hours . CONCLUSIONS These results show that the two interventions had small and varied effects on biomarkers and self-reports of different aspects of health among women . It is suggested that interventions involving a modest reduction in workhours seem to be more effective if these hours are used for physical exercise
