Conclusion Based on available literature , evidence suggests that community-based interventions may reduce the incidence rate of T2DM and may positively affect anthropometric indices and HbA1C .
Due to the heterogeneity observed between trials we recommend more well- design ed RCTs with longer follow-up duration s be executed , to confirm whether community-based interventions lead to reduced T2DM events in the at-risk population of LMIC setting
Background The increasing prevalence of type 2 diabetes mellitus ( T2DM ) can have a substantial impact in low- and middle-income countries ( LMICs ) .
Community-based programs addressing diet , physical activity , and health behaviors have shown significant benefits on the prevention and management of T2DM , mainly in high-income countries .
However , their effects on preventing T2DM in the at-risk population of LMICs have not been thoroughly evaluated .
Long-term nutrition education reduces several risk factors for type 2 diabetes mellitus in Brazilians with impaired glucose tolerance.
The aim of this study was to evaluate the effects of a nutrition education program ( NEP ) on anthropometric , dietetic , and metabolic parameters in high-risk subjects for type 2 diabetes mellitus . Fifty-one participants , both sexes , were r and omly assigned to either the control ( 58.8 % ) or the intervention ( NEP ) group . The intervention group received frequent individual and group nutritional counseling from a team of nutritionists . Participants were assessed at baseline ( M0 ) and after 12 months ( M1 ) for anthropometric , dietetic , and metabolic parameters . The hypothesis was that high-risk subjects for type 2 diabetes mellitus participating in NEP would show an improvement in these parameters . At M1 , the intervention group showed a significant decline in body weight ( -3.4 % ) , body mass index ( -5.7 % ) , cholesterol intake ( -49.5 % ) , fasting glycemia ( -14.0 % ) , fasting insulin ( -9.0 % ) , postpr and ial glycemia ( -21.0 % ) , postpr and ial insulin ( -71.0 % ) , total serum cholesterol ( -23.0 % ) , and glycated hemoglobin ( -24.0 % ) . A decrease in energy intake ( 5 % , P = .06 ) and low-density lipoprotein cholesterol ( 25 % , P = .07 ) was observed in the interventional group , although it did not reach statistical significance . In contrast , the control group presented a significantly higher energy intake ( 19 % , P = .04 ) and a nonsignificant increase in consumption of all macronutrients . The long-term NEP was found to improve anthropometric , dietary , and metabolic parameters in high-risk subjects for type 2 diabetes mellitus
