Influence of Lifestyle on Incident Cardiovascular Disease and Mortality in Patients With Diabetes Mellitus.
BACKGROUND Evidence is limited regarding the impact of healthy lifestyle practice s on the risk of subsequent cardiovascular events among patients with diabetes . OBJECTIVES The purpose of this study was to examine the associations of an overall healthy lifestyle , defined by eating a high- quality diet ( top two-fifths of Alternative Healthy Eating Index ) , nonsmoking , engaging in moderate- to vigorous-intensity physical activity ( ≥150 min/week ) , and drinking alcohol in moderation ( 5 to 15 g/day for women and 5 to 30 g/day for men ) , with the risk of developing cardiovascular disease ( CVD ) and CVD mortality among adults with type 2 diabetes ( T2D ) . METHODS This prospect i ve analysis included 11,527 participants with T2D diagnosed during follow-up ( 8,970 women from the Nurses ' Health Study and 2,557 men from the Health Professionals Follow-Up Study ) , who were free of CVD and cancer at the time of diabetes diagnosis .  Diet and lifestyle factors before and after T2D diagnosis were repeatedly assessed every 2 to 4 years . RESULTS There were 2,311 incident CVD cases and 858 CVD deaths during an average of 13.3 years of follow-up . After multivariate adjustment of covariates , the low-risk lifestyle factors after diabetes diagnosis were each associated with a lower risk of CVD incidence and CVD mortality . The multivariate-adjusted hazard ratios for participants with 3 or more low-risk lifestyle factors compared with 0 were 0.48 ( 95 % confidence interval [ CI ] : 0.40 to 0.59 ) for total CVD incidence , 0.53 ( 95 % CI : 0.42 to 0.66 ) for incidence of coronary heart disease , 0.33 ( 95 % CI : 0.21 to 0.51 ) for stroke incidence , and 0.32 ( 95 % CI : 0.22 to 0.47 ) for CVD mortality ( all p trend < 0.001 ) . The population -attributable risk for poor adherence to the overall healthy lifestyle ( <3 low-risk factors ) was 40.9 % ( 95 % CI : 28.5 % to 52.0 % ) for CVD mortality . In addition , greater improvements in healthy lifestyle factors from pre-diabetes to post-diabetes diagnosis were also significantly associated with a lower risk of CVD incidence and CVD mortality . For each number increment in low-risk lifestyle factors there was a 14 % lower risk of incident total CVD , a 12 % lower risk of coronary heart disease , a 21 % lower risk of stroke , and a 27 % lower risk of CVD mortality ( all p < 0.001 ) . Similar results were observed when analyses were stratified by diabetes duration , sex/cohort , body mass index at diabetes diagnosis , smoking status , and lifestyle factors before diabetes diagnosis . CONCLUSIONS Greater adherence to an overall healthy lifestyle is associated with a substantially lower risk of CVD incidence and CVD mortality  among adults with T2D . These findings further support the tremendous benefits of adopting a healthy lifestyle in reducing the subsequent burden of cardiovascular complications in patients with T2D
