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 .
Methodology of a diabetes prevention translational research project utilizing a community-academic partnership for implementation in an underserved Latino community
Background Latinos comprise the largest racial/ethnic group in the United States and have 2–3 times the prevalence of type 2 diabetes mellitus as Caucasians . Methods and design The Lawrence Latino Diabetes Prevention Project ( LLDPP ) is a community-based translational research study which aims to reduce the risk of diabetes among Latinos who have a ≥ 30 % probability of developing diabetes in the next 7.5 years per a predictive equation . The project was conducted in Lawrence , Massachusetts , a predominantly Caribbean-origin urban Latino community . Individuals were identified primarily from a community health center 's patient panel , screened for study eligibility , r and omized to either a usual care or a lifestyle intervention condition , and followed for one year . Like the efficacious Diabetes Prevention Program ( DPP ) , the LLDPP intervention targeted weight loss through dietary change and increased physical activity . However , unlike the DPP , the LLDPP intervention was less intensive , tailored to literacy needs and cultural preferences , and delivered in Spanish . The group format of the intervention ( 13 group sessions over 1 year ) was complemented by 3 individual home visits and was implemented by individuals from the community with training and supervision by a clinical research nutritionist and a behavioral psychologist . Study measures included demographics , Stern predictive equation components ( age , gender , ethnicity , fasting glucose , systolic blood pressure , HDL-cholesterol , body mass index , and family history of diabetes ) , glycosylated hemoglobin , dietary intake , physical activity , depressive symptoms , social support , quality of life , and medication use . Body weight was measured at baseline , 6-months , and one-year ; all other measures were assessed at baseline and one-year . All surveys were orally administered in Spanish . Results A community-academic partnership enabled the successful recruitment , intervention , and assessment of Latinos at risk of diabetes with a one-year study retention rate of 93%.Trial registration
