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 .
Study protocol for BeWEL: The impact of a BodyWEight and physicaL activity intervention on adults at risk of developing colorectal adenomas
Background Colorectal cancer ( CRC ) is the third most commonly diagnosed cancer and the second highest cause of cancer death in the UK . Most cases occur in people over 50 years and CRC often co-exists with other lifestyle related disorders including obesity , type 2 diabetes mellitus ( T2DM ) and cardiovascular disease ( CVD ) . These diseases share risk factors related to the metabolic syndrome including large body size , abnormal lipids and markers of insulin resistance indicating common aetiological pathways . Methods / Design This 3 year study will be a two-arm , multicentre , r and omised controlled trial comparing the BeWEL lifestyle ( diet , physical activity and behaviour change ) programme against usual care . The pre-trial development will take 6 months and participants will be recruited over a 12 month period and undertake the intervention and follow up for 12 months ( total 24 months recruitment and intervention implementation ) with a further 6 months for data collection , analysis and interpretation . Four hundred and fifty two participants who have had a colorectal adenoma detected and removed ( through the national colorectal screening programme ) will provide 80 % power to detect a weight loss of 7 % over 12 months . Primary outcomes are changes in body weight and waist circumference . Secondary outcomes will include cardiovascular risk factors , psycho-social measures and intervention costs . Discussion The results from this study will enhance the evidence base for lifestyle change in patients at higher risk of chronic disease including obesity related cancers .
