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 .
[Effect of lifestyle interventions on reduction of cardiovascular disease events and its mortality in pre-diabetic patients:long-term follow-up of Da Qing Diabetes Prevention Study].
OBJECTIVE To investigate if a six-year intensive lifestyle intervention in people with pre-diabetes lead to reduction of cardiovascular events and cardiovascular disease ( CVD ) mortality in subsequent 23 years . METHODS Five hundreds and nineteen subjects with normal glucose tolerance ( NGT ) and 577 subjects with impaired glucose tolerance ( IGT ) in Da Qing city were recruited in the study in 1986 . The IGT subjects r and omly assigned to either the no-intervention group or one of three lifestyle intervention groups ( diet , exercise , or diet plus exercise ) to receive a 6-year lifestyle intervention . In 2009 , the participants were followed up to assess the primary outcomes of cardiovascular events and CVD mortality by a question naire and medical records . RESULTS Subjects in IGT no-intervention group had the highest incidences of cardiovascular events ( 44.44 % ) and CVD mortality ( 20.00 % ) , while those in NGT group had the lowest incidences of cardiovascular events ( 29.59 % ) and CVD mortality ( 7.52 % ) after 23-year follow-up . The incidences of cardiovascular events and CVD mortality in IGT intervention subjects were 37.84 % and 12.53 % , respectively . The multivariable analyses showed that , after controlling of age , gender , BMI smoking , blood pressure and cardiovascular event at baseline , the CVD mortality and incidence of cardiovascular events in IGT no-intervention group was 1.89 ( HR = 1.89 , 95%CI 1.11 - 3.22 , P = 0.02 ) and 1.38 ( HR = 1.38 , 95%CI 1.01 - 1.90 , P = 0.04 ) times of those in NGT group . However , the CVD mortality and incidence of cardiovascular events were not different in the IGT intervention group compared with those in the NGT group ( HR = 1.39 , 95%CI 0.89 - 2.18 , P = 0.15 and HR = 1.25 , 95%CI 0.98 - 1.59 , P = 0.07 , respectively ) . CONCLUSIONS Subjects with IGT were at high risk for cardiovascular events and mortality . A six-year lifestyle intervention in this population can reduce both the incidence of cardiovascular event and CVD mortality
