Aims: Little is known about the effect of economic recessions on cardiovascular disease. Therefore, we investigated the association of the economic recession in Finland in the 1990s with the incidence of cardiovascular disease among middle-aged and older women. Methods: A total of 918 women aged 53–73 years were examined for health and socioeconomic position in 1998–2001, as part of the population-based prospective Kuopio Ischaemic Heart Disease Risk Factor Study. The participants were asked whether Finland’s economic recession in the early 1990s had affected their lives socially or economically. The cohort was followed for 18 years, and incident physician-diagnosed cases of cardiovascular disease were obtained through record linkage with the national hospital discharge registry that covers every hospitalisation in Finland. Cox proportional hazards regression models were used to estimate the risk of cardiovascular disease among those with and without exposure to socioeconomic hardships during the recession, after adjusting for possible confounders. Results: At the baseline, 587 women reported having experienced socioeconomic hardships due to the recession. During the 20 years’ follow-up, 501 women developed cardiovascular disease. After adjustment for age, the risk of cardiovascular disease was 27% higher among women exposed to socioeconomic hardships compared to those who were not (hazard ratio 1.27, 95% confidence interval 1.06–1.53, P=0.012). Further adjustments for overall socioeconomic position at baseline, prior cardiovascular health, and lifestyle factors did not attenuate the association (hazard ratio 1.23, 95% confidence interval 1.02–1.5, P=0.029). Conclusions: The early 1990s economic recession was associated with a subsequently increased risk of cardiovascular disease among Finnish women.

Introduction: An association between schizophrenia and urbanicity has long been observed, with studies in many countries, including several from Denmark, reporting that individuals born/raised in densely populated urban settings have an increased risk of developing schizophrenia compared to those born/raised in rural settings. However, these findings have not been replicated in all studies. In particular, a Western Australian study showed a gradient in the opposite direction which disappeared after adjustment for covariates. Given the different findings for Denmark and Western Australia, our aim was to investigate the relationship between schizophrenia and urbanicity in these two regions to determine which factors may be influencing the relationship. Methods: We used population-based cohorts of children born alive between 1980 and 2001 in Western Australia ( N = 428,784) and Denmark ( N = 1,357,874). Children were categorised according to the level of urbanicity of their mother’s residence at time of birth and followed-up through to 30 June 2015. Linkage to State-based registers provided information on schizophrenia diagnosis and a range of covariates. Rates of being diagnosed with schizophrenia for each category of urbanicity were estimated using Cox proportional hazards models adjusted for covariates. Results: During follow-up, 1618 (0.4%) children in Western Australia and 11,875 (0.9%) children in Denmark were diagnosed with schizophrenia. In Western Australia, those born in the most remote areas did not experience lower rates of schizophrenia than those born in the most urban areas (hazard ratio = 1.02 [95% confidence interval: 0.81, 1.29]), unlike their Danish counterparts (hazard ratio = 0.62 [95% confidence interval: 0.58, 0.66]). However, when the Western Australian cohort was restricted to children of non-Aboriginal Indigenous status, results were consistent with Danish findings (hazard ratio = 0.46 [95% confidence interval: 0.29, 0.72]). Discussion: Our study highlights the potential for disadvantaged subgroups to mask the contribution of urban-related risk factors to risk of schizophrenia and the importance of stratified analysis in such cases.

Background Little is known about the use of rehabilitation in the acute care setting and its impact on hospital readmissions. Objective The objective of this study was to examine the association between the intensity of rehabilitation services received during the acute care stay for stroke and the risk of 30-day and 90-day hospital readmission. Design A retrospective cohort analysis of all acute care hospitals in Arkansas and Florida was conducted. Methods Patients (N=64,065) who were admitted for an incident stroke in 2009 or 2010 were included. Rehabilitation intensity was categorized as none, low, medium-low, medium-high, or high based on the sum and distribution of physical therapy, occupational therapy, and speech therapy charges within each hospital. Cox proportional hazards regression was used to estimate hazard ratios, controlling for demographic characteristics, illness severity, comorbidities, hospital variables, and state. Results Relative to participants who received the lowest intensity therapy, those who received higher-intensity therapy had a decreased risk of 30-day readmission. The risk was lowest for the highest-intensity group (hazard ratio=0.86; 95% confidence interval=0.79, 0.93). Individuals who received no therapy were at an increased risk of hospital readmission relative to those who received low-intensity therapy (hazard ratio=1.30; 95% confidence interval=1.22, 1.40). The findings were similar, but with smaller effects, for 90-day readmission. Furthermore, patients who received higher-intensity therapy had more comorbidities and greater illness severity relative to those who received lower-intensity therapy. Limitations The results of the study are limited in scope and generalizability. Also, the study may not have adequately accounted for all potentially important covariates. Conclusions Receipt of and intensity of rehabilitation therapy in the acute care of stroke is associated with a decreased risk of hospital readmission.

Background and objectivesCentral BP measurements provide noninvasive measurement of aortic BP; our objectives were to examine the association of central and brachial BP measurements with risk of cardiovascular outcomes and mortality in patients with CKD and to determine the role of central BP measurement in conjunction with brachial BP in estimating cardiovascular risk.Design, setting, participants, & measurementsIn a prospective, longitudinal study (the Chronic Renal Insufficiency Cohort), central BP was measured in participants with CKD using the SphygmoCorPVx System. Cox proportional hazards models were used for analyses.ResultsMean age of the participants (n=2875) was 60 years old. After a median follow-up of 5.5 years, participants in the highest quartile of brachial systolic BP (≥138 mm Hg) were at higher risk for the composite cardiovascular outcome (hazard ratio, 1.59; 95% confidence interval, 1.17 to 2.17; c statistic, 0.76) but not all-cause mortality (hazard ratio, 1.28; 95% confidence interval, 0.90 to 1.80) compared with those in the lowest quartile. Participants in the highest quartile of central systolic BP were also at higher risk for the composite cardiovascular outcome (hazard ratio, 1.69; 95% confidence interval, 1.24 to 2.31; c statistic, 0.76) compared with participants in the lowest quartile.ConclusionsWe show that elevated brachial and central BP measurements are both associated with higher risk of cardiovascular disease outcomes in patients with CKD. Measurement of central BP does not improve the ability to predict cardiovascular disease outcomes or mortality in patients with CKD compared with brachial BP measurement.

Background: While the association between hypoglycaemia and poor outcomes in diabetes is well established, it is unclear whether such an association is generalizable to those without diabetes. Methods: A total of 8497 participants free of cardiovascular disease and diabetes from the Third National Health and Nutrition Examination Survey were included. We examined the relationship between baseline low (<80 mg/dL) and high (⩾126 mg/dL) fasting plasma glucose compared to normal levels (80–99 mg/dL). Results: Over a median follow-up of 14 years, 2101 deaths occurred, of which 570 were due to cardiovascular disease. In a model adjusted for sociodemographic and cardiovascular disease risk factors, individuals with low fasting plasma glucose were at increased risk of cardiovascular disease and all-cause mortality [hazard ratio = 1.79 (95% confidence interval = 1.04–3.08) and hazard ratio = 1.35 (95% confidence interval = 1.02–1.78), respectively], compared to those with normal fasting plasma glucose. These associations were stronger among men than women for both cardiovascular disease mortality and all-cause mortality. Conclusion: Low fasting plasma glucose in individuals without diabetes is a risk factor for cardiovascular disease and all-cause mortality, especially in men.

ObjectiveMigraine with visual aura is associated with cardioembolic stroke risk. The aim of this study was to test association between migraine with visual aura and atrial fibrillation (AF), in the Atherosclerosis Risk in Communities study.MethodsIn the Atherosclerosis Risk in Communities study, a longitudinal, community-based cohort study, participants were interviewed for migraine history in 1993–1995 and were followed for incident AF through 2013. AF was adjudicated using ECGs, discharge codes, and death certificates. Multivariable Cox proportional hazards models were used to study the relation between migraine and its subtypes with incident AF, compared with controls without headaches. Mediation analysis was conducted to test whether AF was a mediator of migraine with visual aura-associated stroke risk.ResultsOf 11,939 participants assessed for headache and without prior AF or stroke, 426 reported migraines with visual aura, 1,090 migraine without visual aura, 1,018 nonmigraine headache, and 9,405 no headache. Over a 20-year follow-up period, incident AF was noted in 232 (15%) of 1,516 with migraine and 1,623 (17%) of 9,405 without headache. After adjustment for multiple confounders, migraine with visual aura was associated with increased risk of AF compared to no headache (hazard ratio 1.30, 95% confidence interval 1.03–1.62) as well as when compared to migraine without visual aura (hazard ratio 1.39, 95% confidence interval 1.05–1.83). The data suggest that AF may be a potential mediator of migraine with visual aura–stroke risk.ConclusionsMigraine with aura was associated with increased risk of incident AF. This may potentially lead to ischemic strokes.

Objective: To examine the association of number of children birthed/fathered with incident heart disease, accounting for socioeconomic and lifestyle characteristics. Methods: We analyzed data from 24,923 adults 50 and older (55% women) in the Health and Retirement Study. Participants self-reported number of children and doctor-diagnosed incident heart disease. Cox proportional hazards models estimated heart disease risk. Results: Compared to women with one to two children, those with five or more had increased risk of heart disease (hazard ratio [HR] = 1.13, 95% confidence interval [CI] = [1.03, 1.25]). Compared to men with one to two children, those with five or more had a marginally increased risk of heart disease (HR = 1.11, 95% CI = [0.99, 1.25]), but this association attenuated in models adjusting for socioeconomic and lifestyle variables. Compared to men with no children, those with five or more retained a borderline significant association in the fully adjusted model (HR = 1.15, 95% CI = [0.99, 1.35]). Discussion: Social and lifestyle pathways appear to link parenthood to cardiovascular health.

BACKGROUND: Early cognitive dysfunction (eCD) is a subtle form of neurological injury observed in ∼25% of carotid endarterectomy (CEA) patients. Statin use is associated with a lower incidence of eCD in asymptomatic patients having CEA. OBJECTIVE: To determine whether eCD status is associated with worse long-term survival in patients taking and not taking statins. METHODS: This is a post hoc analysis of a prospective observational study of 585 CEA patients. Patients were evaluated with a battery of neuropsychometric tests before and after surgery. Survival was compared for patients with and without eCD stratifying by statin use. At enrollment, 366 patients were on statins and 219 were not. Survival was assessed by using Kaplan-Meier methods and multivariable Cox proportional hazards models. RESULTS: Age ≥75 years (P = .003), diabetes mellitus (P &lt; .001), cardiac disease (P = .02), and statin use (P = .014) are significantly associated with survival univariately (P &lt; .05) by use of the log-rank test. By Cox proportional hazards model, eCD status and survival adjusting for univariate factors within statin and nonstatin use groups suggested a significant effect by association of eCD on survival within patients not taking statin (hazard ratio, 1.61; 95% confidence interval, 1.09–2.40; P = .018), and no significant effect of eCD on survival within patients taking statin (hazard ratio, 0.98; 95% confidence interval, 0.59–1.66; P = .95). CONCLUSION: eCD is associated with shorter survival in patients not taking statins. This finding validates eCD as an important neurological outcome and suggests that eCD is a surrogate measure for overall health, comorbidity, and vulnerability to neurological insult.

Background: High levels of C-reactive protein (CRP) are associated with cardiovascular disease, diabetes and mortality. It is unclear whether changes in CRP or persistently high CRP are associated with these outcomes beyond the baseline measure. Methods: We conducted a prospective cohort analysis of 10,229 participants from the ARIC Study with two measurements of CRP six years apart (at visits 2 and 4, 1990-92 and 1996-98, respectively). CRP was categorized into two groups using a standard cut-point for defining high levels (≥3 vs. <3 mg/L). Six-year change in CRP was categorized as: persistently not high (<3 mg/L), decreasing (≥3 to <3 mg/L), increasing (<3 to ≥3 mg/L), and persistently high (≥3 mg/L). Cox proportional hazards models were used to assess the association between visit 2 CRP, visit 4 CRP and six-year change in CRP and each of the following outcomes from visit 4 through 2010: diabetes, coronary heart disease, ischemic stroke, heart failure and all-cause mortality. Models were adjusted for traditional risk factors at visit 2. Sensitivity analyses additionally adjusted for visit 4 covariates. Results: Persons with CRP ≥3 mg/L at visit 2 or 4 had higher risk of each outcome compared to those with CRP <3 mg/L ( Table ). We observed higher risk of all outcomes in persons with persistently high CRP, and of all outcomes except stroke in persons with increasing CRP, compared to those with CRP <3 mg/L at both visits ( Table ). Persons whose CRP decreased from high to <3 mg/L did not have significantly increased risk of cardiovascular outcomes or diabetes compared to those with CRP persistently <3 mg/L. Results were similar after adjusting for visit 4 covariates. Conclusions: Persons with sustained high levels of CRP or whose CRP increased to high levels had higher risk of diabetes, cardiovascular disease, and death, while those whose levels decreased from high to moderate or low were at lower risk. Multiple measures of CRP may better characterize inflammatory status and provide more comprehensive information regarding long-term risk.

Introduction: Black Americans have higher rates of cardiovascular disease (CVD) mortality compared with whites. Differences in sociodemographic, psychosocial, CVD, and other risk factors may explain increased mortality risk. Methods: We analyzed data from 29,015 REasons for Geographic and Racial Differences in Stroke study participants to determine factors that may explain the higher hazard ratio for CVD and non-CVD mortality in blacks compared with whites. Cause of death was adjudicated by trained investigators. Within age-sex sub-groups, we used Cox proportional hazards regression with progressive adjustment to estimate black:white hazard ratios. Results: Overall, 41.0% of participants were black, and 54.9% were women. Over a mean follow-up of 7.1 years (maximum 12.3 years), 5,299 participants died (1,797 CVD and 3,502 non-CVD deaths). Among participants < 65 years of age, the age and region adjusted black:white hazard ratio for CVD mortality was 2.28 (95% CI: 1.68-3.10) and 2.32 (95% CI: 1.80-3.00) for women and men, respectively, and for participants ≥ 65 was 1.54 (95% CI: 1.30-1.82) and 1.35 (95% CI: 1.16-1.57) for women and men, respectively ( Table ). The higher black:white hazard ratios for CVD mortality were no longer statistically significant after multivariable adjustment, with the largest attenuation occurring with sociodemographic and CVD risk factor adjustment. Among participants < 65 years of age, the age and region adjusted black:white hazard ratios for non-CVD mortality were 1.51 (95% CI: 1.24-1.85) and 1.76 (95% CI: 1.46-2.13) for women and men, respectively, and for participants ≥ 65 was 1.12 (95% CI: 1.00-1.26) and 1.34 (95% CI: 1.20-1.49) for women and men, respectively. The higher black:white hazard ratios for non-CVD mortality were attenuated after adjustment for sociodemographics. Conclusions: Black:white differences are larger for CVD than non-CVD causes of death. The increased CVD mortality for blacks compared with whites is primarily explained by sociodemographic and CVD risk factors.

ABSTRACT Background The Dietary Inflammatory Index (DII) is a comprehensive, literature-derived index for assessing the effect of dietary constituents on inflammatory biomarkers. Several studies have shown an association between DII score and mortality, but there are limited prospective studies in Asian populations. Objectives The aim of this study was to investigate the association between DII score and risk of all-cause, total cardiovascular disease (CVD), stroke, coronary heart disease (CHD), total cancer, digestive cancer, and noncancer/non-CVD mortality in the Japanese population. Methods A total of 58,782 Japanese participants aged 40–79 y who were enrolled in the Japan Collaborative Cohort Study during 1988–1990 were included in the analysis. DII scores were calculated based on a food-frequency questionnaire. HRs and 95% CIs for mortality according to DII quintiles were estimated using Cox proportional hazards models. Results During the median follow-up period of 19.3 y, a total of 11,693 participants died. The multivariable HR for all-cause mortality for the highest compared with the lowest DII quintiles was 1.13 (95% CI: 1.05, 1.21). For CVD mortality, the highest multivariable HRs were 1.30 (95% CI: 1.13, 1.49), 1.29 (95% CI: 1.05, 1.59), and 1.30 (95% CI: 0.96, 1.76) for total CVD, stroke, and CHD, respectively. No significant associations were observed between DII and risk of total cancer, digestive cancer, and noncancer/non-CVD mortality. Conclusion Our findings suggest that a higher DII was associated with an increased risk of all-cause and CVD mortality among Japanese adults.
