Ontology highlight
ABSTRACT: Context
Lower dehydroepiandrosterone-sulfate (DHEA-S) levels have been inconsistently associated with coronary heart disease (CHD) and mortality. Data are limited for heart failure (HF) and association between DHEA-S change and events.Objective
Assess associations between low DHEA-S/DHEA-S change and incident HF hospitalization, CHD, and mortality in older adults.Design
DHEA-S was measured in stored plasma from visits 4 (1996-1998) and 5 (2011-2013) of the Atherosclerosis Risk in Communities study. Follow-up for incident events: 18 years for DHEA-S level; 5.5 years for DHEA-S change.Setting
General community.Participants
Individuals without prevalent cardiovascular disease (n = 8143, mean age 63 years).Main outcome measure
Associations between DHEA-S and incident HF hospitalization, CHD, or mortality; associations between 15-year change in DHEA-S (n = 3706) and cardiovascular events.Results
DHEA-S below the 15th sex-specific percentile of the study population (men: 55.4 µg/dL; women: 27.4 µg/dL) was associated with increased HF hospitalization (men: hazard ratio [HR] 1.30, 95% confidence interval [CI], 1.07-1.58; women: HR 1.42, 95% CI, 1.13-1.79); DHEA-S below the 25th sex-specific percentile (men: 70.0 µg/dL; women: 37.1 µg/dL) was associated with increased death (men: HR 1.12, 95% CI, 1.01-1.25; women: HR 1.19, 95% CI, 1.03-1.37). In men, but not women, greater percentage decrease in DHEA-S was associated with increased HF hospitalization (HR 1.94, 95% CI, 1.11-3.39). Low DHEA-S and change in DHEA-S were not associated with incident CHD.Conclusions
Low DHEA-S is associated with increased risk for HF and mortality but not CHD. Further investigation is warranted to evaluate mechanisms underlying these associations.

Project description:Previous research suggests greater risk of coronary heart disease with lower levels of the adrenal steroid dehydroepiandrosterone sulfate (DHEAS). No studies have examined the association between DHEAS and risk of ischemic stroke. DHEAS may influence ischemic stroke risk through atherosclerotic-related mechanisms (endothelial function and smooth muscle cell proliferation) or insulin resistance.Between 1989 and 1990, 32 826 women without prior stroke in the Nurses' Health Study, an observational cohort, provided blood samples and were followed up for cardiovascular events. Among this sample, using a nested case-control design, 461 ischemic strokes were confirmed by medical records by 2006. Cases were matched to controls free of stroke at the time of the index case and by age, race, menopausal status, postmenopausal hormone use, smoking status, and date of sample collection. Multivariable conditional logistic regression was used.Median DHEAS levels did not differ between cases (median=58.7) and controls (median=66.0; P=0.10). Conditional on matching factors, the lowest DHEAS quartile exhibited a relative risk of 1.30 for ischemic stroke (95% confidence interval, 0.88-1.94), compared with the highest quartile and marginally unchanged when adjusted for confounders (relative risk=1.33; 95% confidence interval, 0.87-2.02). When modeled as a binary variable dichotomized at the lowest quartile, women with low DHEAS (?the lowest quartile) had a significantly increased multivariable adjusted risk of ischemic stroke compared with those with higher levels (relative risk=1.41; 95% confidence interval, 1.03-1.92).Lower DHEAS levels were associated with a greater risk of ischemic stroke, even after adjustment for potential confounders. These novel observations warrant confirmation in other populations.

Project description:Background and Purpose: Previous studies found inconsistent results for the relationship between Alzheimer's disease and the levels of dehydroepiandrosterone and dehydroepiandrosterone sulfate. This study performed a systematic review and meta-analysis to evaluate previous studies' results on this relationship. Method: Studies related to this outcome were obtained using a systematic search from the electronic databases of PubMed, Embase, Web of Science, and Psyc-ARTICLES in March 2018. The random-effects model was used to measure the strength of the association between Alzheimer's disease and the levels of dehydroepiandrosterone and dehydroepiandrosterone sulfate, using the standardized mean difference. Results: Thirty-one eligible studies were included in the final analysis. There was no statistically significant association between the level of dehydroepiandrosterone and Alzheimer's disease (standardized mean difference: 0.51, 95% confidence interval: -0.44 to 1.45, Z = 1.06, p = 0.29). On the other hand, lower level dehydroepiandrosterone sulfate was observed in patients with Alzheimer's disease than in controls (standardized mean difference: -0.69, 95% confidence interval: -1.17 to -0.22, Z = -2.84, p < 0.01). Conclusion: Decreased dehydroepiandrosterone sulfate concentrations may be an important indicator for Alzheimer's disease, although whether dehydroepiandrosterone sulfate could be used as a diagnostic tool requires further research.

Project description:A few studies indicate that women with prolonged time-to-pregnancy (TTP) have an increased risk of cardiovascular disease (CVD). This has not been studied in men. We evaluated CVD risk by self-reported TTP among parous women (n = 64,064) and men (n = 50,533) participating in the Norwegian Mother, Father and Child Cohort Study. TTP was categorized as 0-3 (reference), 4-12 and > 12 months. CVD diagnosed between 2008 and 2017 were available from the national patient and general practitioner databases. Risk of CVD by TTP was estimated using Cox regression adjusting for baseline age, education, BMI, smoking, diabetes, and number of offspring in both sexes, and history of endometriosis, ovarian cysts, preterm birth and pre-eclampsia for women. Mean age was 33 for women and 35 for men at baseline (years). The rate of any CVD was 24 per 1000 person years among women and 22 per 1000 person years among men. Longer TTP was associated with increased rate of CVD among women, with adjusted hazard ratios (HRs) of 1.07 (95% CI: 1.03, 1.09) for TTP 4-12 months and 1.14 (1.08, 1.20) for TTP > 12 months. Among men, respective HRs for CVD were 1.06 (1.00, 1.10) for TTP 4-12 months and 1.07 (1.01, 1.14) for TTP > 12 months. We observed sex-differences in the relationship with CVD subtypes but none were statistically significant. In conclusion, both men and women with a prolonged TTP had a small increased risk of CVD, clinical significance of which is unclear. Further studies are necessary to investigate in detail what underlying causes of prolonged TTP might be reflected in the increased risk of CVD. Longer follow-up is required to confirm these preliminary findings.

Project description:OBJECTIVE:To examine the association between chocolate intake and the risk of future cardiovascular events. METHODS:We conducted a prospective study using data from the European Prospective Investigation into Cancer (EPIC)-Norfolk cohort. Habitual chocolate intake was quantified using the baseline food frequency questionnaire (1993-1997) and cardiovascular end points were ascertained up to March 2008. A systematic review was performed to evaluate chocolate consumption and cardiovascular outcomes. RESULTS:A total of 20,951 men and women were included in EPIC-Norfolk analysis (mean follow-up 11.3±2.8?years, median 11.9?years). The percentage of participants with coronary heart disease (CHD) in the highest and lowest quintile of chocolate consumption was 9.7% and 13.8%, and the respective rates for stroke were 3.1% and 5.4%. The multivariate-adjusted HR for CHD was 0.88 (95% CI 0.77 to 1.01) for those in the top quintile of chocolate consumption (16-99?g/day) versus non-consumers of chocolate intake. The corresponding HR for stroke and cardiovascular disease (cardiovascular disease defined by the sum of CHD and stroke) were 0.77 (95% CI 0.62 to 0.97) and 0.86 (95% CI 0.76 to 0.97). The propensity score matched estimates showed a similar trend. A total of nine studies with 157,809 participants were included in the meta-analysis. Higher compared to lower chocolate consumption was associated with significantly lower CHD risk (five studies; pooled RR 0.71, 95% CI 0.56 to 0.92), stroke (five studies; pooled RR 0.79, 95% CI 0.70 to 0.87), composite cardiovascular adverse outcome (two studies; pooled RR 0.75, 95% CI 0.54 to 1.05), and cardiovascular mortality (three studies; pooled RR 0.55, 95% CI 0.36 to 0.83). CONCLUSIONS:Cumulative evidence suggests that higher chocolate intake is associated with a lower risk of future cardiovascular events, although residual confounding cannot be excluded. There does not appear to be any evidence to say that chocolate should be avoided in those who are concerned about cardiovascular risk.

Project description:BackgroundAlthough studies have linked vitamin D deficiency to an increased risk of cardiovascular disease (CVD), evidence regarding whether vitamin D intake from foods or supplements is prospectively associated with lower CVD risk in healthy humans is limited and inconclusive.ObjectiveThe objective was to comprehensively evaluate the associations between both dietary and supplemental vitamin D and CVD risk.DesignIn the Nurses' Health Study (1984-2006) and the Health Professionals Follow-Up Study (1986-2006)-consisting of 74,272 women and 44,592 men, respectively, who were free of CVD and cancer at baseline-we prospectively examined the association between vitamin D intake and incident CVD.ResultsOver a total of 2,280,324 person-years of follow-up, we identified 9886 incident cases of coronary heart disease and stroke. After multivariate adjustment for age and other CVD risk factors, a higher total vitamin D intake (from foods and supplements) was associated with a decreased risk of CVD in men but not in women; the relative risks (95% CIs) for a comparison of participants who met the Dietary Reference Intake of vitamin D (?600 IU/d) with participants whose vitamin D intake was <100 IU/d were 0.84 (0.72, 0.97; P for trend = 0.009) for men and 1.02 (0.89, 1.17; P for trend = 0.12) for women.ConclusionsThese observations suggest that a higher intake of vitamin D is associated with a lower risk of CVD in men but not in women. Further research is needed to confirm these findings and to elucidate a biological basis for potential sex differences.

Project description:ObjectiveTo examine whether higher plasma urate concentrations are associated with a lower risk of developing Parkinson disease (PD) and whether there is a sex difference in the potential urate-PD relationship.MethodsWe conducted a nested case-control study based on 90,214 participants of 3 ongoing US cohorts. We identified 388 new PD cases (202 men and 186 women) since blood collection, which were then matched to 1,267 controls. PD cases were confirmed by medical record review. Conditional logistic regression estimated relative risks (RRs) and 95% confidence intervals (95% CIs), after adjustment for age, smoking, caffeine intake, plasma concentrations of cholesterol and ferritin, and other covariates. We also conducted a meta-analysis to combine our study with 3 previously published prospective studies on urate and PD risk.ResultsIn the present nested case-control study, the multivariate-adjusted RRs of PD comparing extreme quartiles of urate were 0.63 (95% CI 0.35, 1.10; ptrend = 0.049) in men and 1.04 (95% CI 0.61, 1.78; ptrend = 0.44) in women (pheterogeneity = 0.001). In the meta-analysis, the pooled RRs comparing 2 extreme quartiles of urate were 0.63 (95% CI 0.42, 0.95) in men and 0.89 (95% CI 0.57, 1.40) in women.ConclusionWe observed that men, but not women, with higher urate concentrations had a lower future risk of developing PD, suggesting that urate could be protective against PD risk or could slow disease progression during the preclinical stage of disease.

Project description:Adherence to several diet quality scores, including the Alternative Healthy Eating Index, Alternative Mediterranean Diet score, and Dietary Approach to Stop Hypertension, has been associated with lower risk of cardiovascular disease (CVD), but little is known about how changes in these scores over time influence subsequent CVD risk.We analyzed the association between 4-year changes in the 3 diet quality scores (Alternative Healthy Eating Index, Alternative Mediterranean Diet score, and Dietary Approach to Stop Hypertension) and subsequent cardiovascular disease (CVD) risk among 29?343 men in the Health Professionals Follow-up Study and 51?195 women in the Nurses' Health Study (1986-2010). During 1?394?702 person-years of follow-up, we documented 11?793 CVD cases. Compared with participants whose diet quality remained relatively stable in each 4-year period, those with the greatest improvement in diet quality scores had a 7% to 8% lower CVD risk in the subsequent 4-year period (pooled hazard ratio, 0.92 [95% confidence interval (CI), 0.87-0.99] for the Alternative Healthy Eating Index; 0.93 [95% CI, 0.85-1.02] for the Alternative Mediterranean Diet score; and 0.93 [95% CI, 0.87-0.99] for the Dietary Approach to Stop Hypertension; all P for trend <0.05). In the long term, increasing the diet scores from baseline to the first 4-year follow-up was associated with lower CVD risk during the next 20 years (7% [95% CI, 1-12] for the Alternative Healthy Eating Index, and 9% [95% CI, 3-14] for the Alternative Mediterranean Diet score). A decrease in diet quality scores was associated with significantly elevated risk of CVD in subsequent time periods.Improving adherence to diet quality scores over time is associated with significantly lower CVD risk in both the short term and long term.

Project description:The association between bone mineral density (BMD) and cardiovascular disease (CVD) is not fully understood. We evaluated BMD as a risk factor for cardiovascular disease and specifically atrial fibrillation (AF), acute myocardial infarction (AMI), ischemic (IS) and hemorrhagic stroke (HS) and heart failure (HF) in men and women. This prospective population cohort utilized data on 22 857 adults from the second and third surveys of the HUNT Study in Norway free from CVD at baseline. BMD was measured using single and dual-energy X-ray absorptiometry in the non-dominant distal forearm and T-score was calculated. Hazard ratios (HR) and 95% confidence intervals (CI) were calculated from adjusted cox proportional hazards models. The analyses were sex-stratified, and models were adjusted for age, age-squared, BMI, physical activity, smoking status, alcohol use, and education level. Additionally, in women, we adjusted for estrogen use and postmenopause. During a mean follow-up of 13.6 ± 5.7 years, 2 928 individuals (12.8%) developed fatal or non-fatal CVD, 1 020 AF (4.5%), 1 172 AMI (5.1%), 1 389 IS (6.1%), 264 HS (1.1%), and 464 HF (2.0%). For every 1 unit decrease in BMD T-score the HR for any CVD was 1.01 (95% CI 0.98 to 1.04) in women and 0.99 (95% CI 0.94 to 1.03) in men. Point estimates for the four cardiovascular outcomes ranged from slightly protective (HR 0.95 for AF in men) to slightly deleterious (HR 1.12 for HS in men). We found no evidence of association of lower distal forearm BMD with CVD, AF, AMI, IS, HS, and HF.

Project description:BackgroundInflammation plays an important role in cardiovascular disease (CVD) development. Diet modulates inflammation; however, it remains unknown whether dietary patterns with higher inflammatory potential are associated with long-term CVD risk.ObjectivesThis study sought to examine whether proinflammatory diets are associated with increased CVD risk.MethodsWe prospectively followed 74,578 women from the Nurses' Health Study (NHS) (1984-2016), 91,656 women from the NHSII (1991-2015), and 43,911 men from the Health Professionals Follow-up Study (1986-2016) who were free of CVD and cancer at baseline. Diet was assessed by food frequency questionnaires every 4 years. The inflammatory potential of diet was evaluated using a food-based empirical dietary inflammatory pattern (EDIP) score that was pre-defined based on levels of 3 systemic inflammatory biomarkers.ResultsDuring 5,291,518 person-years of follow-up, we documented 15,837 incident CVD cases, including 9,794 coronary heart disease (CHD) cases and 6,174 strokes. In pooled analyses of the 3 cohorts, after adjustment for use of anti-inflammatory medications and CVD risk factors including body mass index, a higher dietary inflammatory potential, as indicated by higher EDIP scores, was associated with an increased risk of CVD (hazard ratio [HR] comparing the highest to lowest quintiles: 1.38; 95% confidence interval [CI]: 1.31 to 1.46; p for trend <0.001), CHD (HR: 1.46; 95% CI: 1.36 to 1.56; p for trend <0.001), and stroke (HR: 1.28; 95% CI: 1.17- to 1.39; p for trend <0.001). These associations were consistent across cohorts and between sexes, and they remained significant after further adjustment for other dietary quality indices. In a subset of study participants (n = 33,719), a higher EDIP was associated with a higher circulating profile of proinflammatory biomarkers, lower levels of adiponectin, and an unfavorable blood lipid profile (p < 0.001).ConclusionsDietary patterns with a higher proinflammatory potential were associated with higher CVD risk. Reducing the inflammatory potential of the diet may potentially provide an effective strategy for CVD prevention.

Project description:We aimed to investigate the risks of cardiovascular diseases associated with specific occupations, using a nation-wide, multicentre, hospital-based registry data from the Inpatient Clinico-Occupational Survey. The analysis included 539,110 controls (non-circulatory disease) and 23,792 cases (cerebral infarction, intracerebral/subarachnoid hemorrhage, acute myocardial infarction) aged ≥ 20 years who were initially hospitalized during 2005-2015. The participants' occupational and clinical histories were collected by interviewers and medical doctors. Occupations were coded into 81 categories according to the Japanese standard occupation classification. Multivariable logistic regression analysis adjusted for age, admission year and hospital, smoking, alcohol consumption, hypertension, and shift-work was conducted by sex using general clerical workers as the reference. Increased risks of cerebral infarction, intracerebral hemorrhage, subarachnoid hemorrhage, and acute myocardial infarction, were observed in 15, 20, 25, and 1 occupation(s) in men, and 9, 2, 2, and 10 occupations in women. Motor vehicle drivers, food and drink preparatory workers, fishery workers, cargo workers, civil engineer workers, and other manual workers in men and other manual workers in women faced increased risks of all three stroke subtypes. Our findings demonstrate associations between specific occupations and the risk of cardiovascular disease incidence and suggest that the risk may vary by occupation.
