Similar effects also appeared in SBP and DBP categories regardless of follow-up duration .
PA+D interventions had larger improvement effects on CVD risk factors than PA alone interventions .
In adults without IGT or diabetes , lifestyle interventions result ed in significant improvements in SBP , DBP , TC , LDL-C , HDL-C , and TG , and might further reduce CVD risk
Structured lifestyle interventions can reduce diabetes incidence and cardiovascular disease ( CVD ) risk among persons with impaired glucose tolerance ( IGT ) , but it is unclear whether they should be implemented among persons without IGT .
We conducted a systematic review and meta-analyses to assess the effectiveness of lifestyle interventions on CVD risk among adults without IGT or diabetes .
Randomized controlled trial of a new dietary education program to prevent type 2 diabetes in a high-risk group of Japanese male workers.
OBJECTIVE The aim of this study was to assess the effectiveness of a new dietary education ( NDE ) program in reducing plasma glucose ( PG ) levels in Japanese male workers at high risk for type 2 diabetes through a r and omized controlled trial . RESEARCH DESIGN AND METHODS We r and omly assigned 173 high-risk men ( mean age , 55 years ) to either the NDE or the  control ( conventional dietary education )  group . Each subject in the NDE group received two individualized interventions especially aim ed at reducing total energy intake at dinner by modifying dietary intake . The control group received conventional group counseling . An " overintake/underintake fraction " for total energy intake was used to measure the status of dietary intake . Our hypothesis was that the NDE group would have a 10 % decrease in 2-h PG 1 year after the start of the education . Outcome measures were compared with ANCOVA by adjusting for baseline values . RESULTS The NDE group had a significantly lower total energy intake at dinner and daily than the control group . The adjusted differences in changes from baseline in the absolute value of the ' overintake/underintake fraction ' were -15.3 % ( 95 % CI -24.6 to -6.0 % , P = 0.002 ) for dinner and -6.0 % ( -9.8 to -2.2 % , P = 0.002 ) for daily [ corrected ] . The NDE group had a decreased 2-h PG after 1 year , whereas that value was increased in the control group . The adjusted difference in the percent change of 2-h PG was significant ( -15.2 % , -22.0 to -8.4 % , P < 0.001 ) . CONCLUSIONS The NDE was shown to reduce glucose levels in high-risk subjects for type 2 diabetes
