Healthy lifestyle through young adulthood and the presence of low cardiovascular disease risk profile in middle age: the Coronary Artery Risk Development in (Young) Adults (CARDIA) study.

ABSTRACT: BACKGROUND:A low cardiovascular disease risk profile (untreated cholesterol <200 mg/dL, untreated blood pressure <120/<80 mm Hg, never smoking, and no history of diabetes mellitus or myocardial infarction) in middle age is associated with markedly better health outcomes in older age, but few middle-aged adults have this low risk profile. We examined whether adopting a healthy lifestyle throughout young adulthood is associated with the presence of the low cardiovascular disease risk profile in middle age. METHODS AND RESULTS:The Coronary Artery Risk Development in (Young) Adults (CARDIA) study sample consisted of 3154 black and white participants 18 to 30 years of age at year 0 (1985-1986) who attended the year 0, 7, and 20 examinations. Healthy lifestyle factors defined at years 0, 7, and 20 included average body mass index <25 kg/m(2), no or moderate alcohol intake, higher healthy diet score, higher physical activity score, and never smoking. Mean age (25 years) and percentage of women (56%) were comparable across groups defined by number of healthy lifestyle factors. The age-, sex-, and race-adjusted prevalences of low cardiovascular disease risk profile at year 20 were 3.0%, 14.6%, 29.5%, 39.2%, and 60.7% for people with 0 or 1, 2, 3, 4, and 5 healthy lifestyle factors, respectively (P for trend <0.0001). Similar graded relationships were observed for each sex-race group (all P for trend <0.0001). CONCLUSIONS:Maintaining a healthy lifestyle throughout young adulthood is strongly associated with a low cardiovascular disease risk profile in middle age. Public health and individual efforts are needed to improve the adoption and maintenance of healthy lifestyles in young adults.

Project description:Although cardiorespiratory fitness (CRF) is prognostic in older adults, the effect of CRF during early adulthood on long-term cardiovascular structure, function, and prognosis is less clear.To examine whether CRF in young adults is associated with long-term clinical outcome and subclinical cardiovascular disease (CVD).Prospective study of 4872 US adults aged 18 to 30 years who underwent treadmill exercise testing at a baseline study visit from March 25, 1985, to June 7, 1986, and 2472 individuals who underwent a second treadmill test 7 years later. Median follow-up was 26.9 years, with assessment of obesity, left ventricular mass and strain, coronary artery calcification (CAC), and vital status and incident CVD. Follow-up was complete on August 31, 2011, and data were analyzed from recruitment through the end of follow-up.The presence of CAC was assessed by computed tomography at years 15 (2000-2001), 20 (2005-2006), and 25 (2010-2011), and left ventricular mass was assessed at years 5 (1990-1991) and 25 (with global longitudinal strain). Incident CVD and all-cause mortality were adjudicated.Of the 4872 individuals, 273 (5.6%) died and 193 (4.0%) experienced CVD events during follow-up. After comprehensive adjustment, each additional minute of baseline exercise test duration was associated with a 15% lower hazard of death (hazard ratio [HR], 0.85; 95% CI, 0.80-0.91; P?<?.001) and a 12% lower hazard of CVD (HR, 0.88; 95% CI, 0.81-0.96; P?=?.002). Higher levels of baseline CRF were associated with significantly lower left ventricular mass index (??=?-0.24; 95% CI, -0.45 to -0.03; P?=?.02) and significantly better lobal longitudinal strain (??=?-0.09; 95% CI, -0.14 to -0.05; P?<?.001) at year 25. Fitness was not associated with CAC. A 1-minute reduction in fitness by year 7 was associated with 21% and 20% increased hazards of death (HR, 1.21; 95% CI, 1.07-1.37; P?=?.002) and CVD (HR, 1.20; 95% CI, 1.06-1.37; P?=?.006), respectively, along with a more impaired strain (??=?0.15; 95% CI, 0.08-0.23; P?<?.001). No association between change in fitness and CAC was found.Higher levels of fitness at baseline and improvement in fitness early in adulthood are favorably associated with lower risks for CVD and mortality. Fitness and changes in fitness are associated with myocardial hypertrophy and dysfunction but not CAC. Regular efforts to ascertain and improve CRF in young adulthood may play a critical role in promoting cardiovascular health and interrupting early CVD pathogenesis.

Project description:ImportanceData are sparse regarding which blood pressure (BP) components in young adulthood optimally determine cardiovascular disease (CVD) by middle age.ObjectivesTo assess which BP components best determine incident CVD events in young adults and determine whether these associations vary by race and age at BP measurement.Design, setting, and participantsUsing data from the Coronary Artery Risk Development in Young Adults (CARDIA) study, this study assessed the longitudinal race-stratified associations between BP and cardiovascular outcomes. CARDIA is a community-based cohort that recruited black and white individuals (age range, 18-30 years) from March 26, 1985, through June 7, 1986. CARDIA followed up participants for up to 28 years, and 94% of the surviving cohort completed at least 1 telephone interview or examination from August 2009 through August 2014.ExposuresBlood pressures measubred at baseline (Y0) and 15 years later (Y15).Main outcomes and measuresComposite CVD events, including coronary heart disease, stroke, heart failure, and other vascular diseases.ResultsA total of 4880 participants participated in the study (mean [SD] age, 24.9 [3.6] years at Y0 and 25.0 [3.6] years at Y15; 2223 male [45.6%] at Y0 and 1800 [44.2%] at Y15; 2657 female [54.4%] at Y0 and 2277 [55.8%] at Y0; 2473 black individuals [50.7%] at Y0 and 1994 [48.9%] at Y15; and 2407 white individuals [49.3%] at Y0 and 2083 [51.1%] at Y15). The mean SBP/DBP was 112/69 mm Hg in blacks and 109/68 mm Hg in whites at Y0 and 117/77 mm Hg in blacks and 110/72 mm Hg in whites at Y15. During a 25-year follow-up from Y0, 210 CVD events occurred (twice as many events in blacks [n?=?140] compared with whites), of which 131 (87 in blacks) occurred after Y15. With adjustments for covariates, results from Cox proportional hazards models, including SBP and DBP, jointly suggested that, at Y0, SBP (hazard ratio [HR] per 1-SD increase, 1.32; 95% CI, 1.09-1.61) but not DBP (HR, 1.05; 95% CI, 0.88-1.26) was associated with CVD risk in blacks, whereas DBP (HR, 1.74; 95% CI, 1.21-2.50) but not SBP (HR, 0.82; 95% CI, 0.57-1.18) was associated with CVD risk in whites. At Y15, SBP was the strongest indicator of CVD in blacks (HR, 1.64; 95% CI, 1.25-2.16) and whites (HR, 1.67; 95% CI, 1.02-2.69).Conclusions and relevanceThis study questions the classic view that DBP is more able to identify future CVD events than SBP in all individuals younger than 50 years. In young adulthood, SBP in black individuals and DBP in white individuals were the most robust indicators of future CVD. In middle-age, SBP in both races identified risk of incident CVD.

Project description:BackgroundFew studies have evaluated whether plant-centered diets prevent progression of early stage chronic kidney disease (CKD).ObjectivesWe examined the association between plant-centered diet quality and early CKD markers.MethodsWe prospectively examined 2869 black and white men and women in the Coronary Artery Risk Development in Young Adults Study free of diagnosed kidney failure in 2005-2006 [examination year 20 (Y20); mean age: 45.3 ± 3.6 y]. CKD marker changes from Y20 to 2015-2016 (Y30) were considered, including estimated glomerular filtration rate (eGFR; serum creatinine), urinary albumin-to-creatinine ratio (ACR), and both. Diet was assessed through interviewer-administered diet histories at Y0, Y7, and Y20, and plant-centered diet quality was quantified with the A Priori Diet Quality Score (APDQS). Linear regression models were used to examine the association of APDQS and subsequent 10-y changes in CKD markers.ResultsAfter adjustment for sociodemographic, behavioral, and diet factors, we found that higher APDQS was related to less adverse changes in CKD markers in the subsequent 10-y period. Compared with the lowest APDQS quintile, the highest quintile was associated with an attenuated increase in lnACR (-0.25 mg/g; 95% CI: -0.37, -0.13 mg/g; P-trend < 0.001), whereas the highest quintile was associated with an attenuated decrease in eGFR (4.45 mL·min-1·1.73 m-2; 95% CI: 2.46, 6.43 mL·min-1·1.73 m-2). There was a 0.50 lower increase in combined CKD markers [ln(ACR) z score - eGFR z score] when comparing the extreme quintiles. Associations remained similar after further adjustment for hypertension, diabetes, and obesity as potential mediating factors. The attenuated worsening CKD marker changes associated with higher APDQS strengthened across increasing initial CKD category; those with the best diet and microalbuminuria in Y10-Y20 returned to high normal albuminuria (all P-interaction < 0.001).ConclusionsIndividuals who consumed plant-centered, high-quality diets were less likely to experience deterioration of kidney function through midlife, especially among participants with initial stage characterized as mild CKD.
