Supper Timing and Cardiovascular Mortality: The Japan Collaborative Cohort Study

Evidence on the role of supper timing in the development of cardiovascular disease (CVD) is limited. In this study, we examined the associations between supper timing and risks of mortality from stroke, coronary heart disease (CHD), and total CVD. A total of 28,625 males and 43,213 females, aged 40 to 79 years, free from CVD and cancers at baseline were involved in this study. Participants were divided into three groups: the early supper group (before 8:00 p.m.), the irregular supper group (time irregular), and the late supper group (after 8:00 p.m.). Cox proportional hazards regression models were used to calculate hazard ratios (HRs) for stroke, CHD, and total CVD according to the supper time groups. During the 19-year follow-up, we identified 4706 deaths from total CVD. Compared with the early supper group, the multivariable HR of hemorrhagic stroke mortality for the irregular supper group was 1.44 (95% confidence interval [CI]: 1.05–1.97). There was no significant association between supper timing and the risk of mortality from other types of stroke, CHD, and CVD. We found that adopting an irregular supper timing compared with having dinner before 8:00 p.m. was associated with an increased risk of hemorrhagic stroke mortality.

The aim of this study was to explore sex-specific associations between systolic blood pressure (SBP), hypertension, and the risk of incident atrial fibrillation (AF) subtypes, including paroxysmal, persistent, and permanent AF, in a general population. A total of 13,137 women and 11,667 men who participated in the fourth survey of the Tromsø Study (1994–1995) were followed up for incident AF until the end of 2016. Cox proportional hazards regression analysis was conducted using fractional polynomials for SBP to provide sex- and AF-subtype-specific hazard ratios (HRs) for SBP. An SBP of 120 mmHg was used as the reference. Models were adjusted for other cardiovascular risk factors. Over a mean follow-up of 17.6 ± 6.6 years, incident AF occurred in 914 (7.0%) women (501 with paroxysmal/persistent AF and 413 with permanent AF) and 1104 (9.5%) men (606 with paroxysmal/persistent AF and 498 with permanent AF). In women, an SBP of 180 mmHg was associated with an HR of 2.10 (95% confidence interval [CI] 1.60–2.76) for paroxysmal/persistent AF and an HR of 1.80 (95% CI 1.33–2.44) for permanent AF. In men, an SBP of 180 mmHg was associated with an HR of 1.90 (95% CI 1.46–2.46) for paroxysmal/persistent AF, while there was no association with the risk of permanent AF. In conclusion, increasing SBP was associated with an increased risk of both paroxysmal/persistent AF and permanent AF in women, but only paroxysmal/persistent AF in men. Our findings highlight the importance of sex-specific risk stratification and optimizing blood pressure management for the prevention of AF subtypes in clinical practice.

Evidence for cardioprotective effects of lycopene is inconsistent. Studies of circulating lycopene generally report inverse associations with CVD risk, but studies based on lycopene intake do not. The failure of dietary studies to support the findings based on biomarkers may be due in part to misclassification of lycopene intakes. To address this potential misclassification, we used repeated measures of intake obtained over 10 years to characterise the relationship between lycopene intake and the incidence of CVD (n314), CHD (n171) and stroke (n99) in the Framingham Offspring Study. Hazard ratios (HR) for incident outcomes were derived from Cox proportional hazards regression models using logarithmically transformed lycopene intake adjusted for CVD risk factors and correlates of lycopene intake. HR were interpreted as the increased risk for a 2·7-fold difference in lycopene intake, a difference approximately equal to its interquartile range. Using an average of three intake measures with a 9-year follow-up, lycopene intake was inversely associated with CVD incidence (HR 0·83, 95 % CI 0·70, 0·98). Using an average of two intake measures and 11 years of follow-up, lycopene intake was inversely associated with CHD incidence (HR 0·74, 95 % CI 0·58, 0·94). Lycopene intake was unrelated to stroke incidence. The present study of lycopene intake and CVD provides supporting evidence for an inverse association between lycopene and CVD risk; however, additional research is needed to determine whether lycopene or other components of tomatoes, the major dietary source of lycopene, are responsible for the observed association.

Objectives. To evaluate whether serum interleukin-6 (IL-6) is associated with increased risk of mortality in coronary artery disease (CAD) patients.Methods. We performed a prospective cohort study of 718 CAD patients from the Guangzhou Cardiovascular Disease Cohort (GCDC) study. Multivariable-adjusted Cox proportional hazards regression analyses were used to examine the association between serum IL-6 with all-cause and cardiovascular mortality.Results. During the 1663 person-years of followup, the cumulative all-cause mortality and cardiovascular mortality were 6.5% (n=47) and 3.3% (n=24), respectively. The mean length of followup was2.32±0.81years. In the multivariable analyses, a one-SD increment in log-transformed serum IL-6 was positively associated with an increased risk of all-cause and cardiovascular mortality, with hazard ratios (HR) of 2.93 (95% CI, 2.11–4.08) and 2.04 (95% CI, 1.34–3.68) within the patients combined and 2.98 (95% CI, 2.12–4.18) and 3.10 (95% CI, 1.98–4.85) within males, respectively. Patients in the highest serum IL-6 tertile versus the lowest tertile were at higher risk of all-cause and cardiovascular mortality, with HR of 17.12 (95% CI 3.11–71.76) and 8.68 (95% CI, 1.88–37.51), respectively.Conclusions. In hospitalized patients with CAD, serum IL-6 is significantly associated with all-cause and cardiovascular mortality.

Abstract Visual impairment has emerged as a potential modifiable risk factor for dementia. However, there are a lack of large studies with objective measures of vison and with more than ten years of follow-up. We investigated whether visual impairment is associated with an increased risk of incident dementia in UK Biobank and EPIC-Norfolk. In both cohorts, visual acuity was measured using a “logarithm of the minimum angle of resolution” (LogMAR) chart and categorised as no (≤0.30 LogMAR), mild (>0.3 - ≤0.50 LogMAR), and moderate to severe (>0.50 LogMAR) impairment. Dementia was ascertained through linkage to electronic medical records. After restricting to those aged ≥60 years, without prevalent dementia and with eye measures available, the analytic samples consisted of 62,206 UK Biobank and 7,337 EPIC-Norfolk participants, respectively. In UK Biobank and EPIC-Norfolk. respectively, 1,113 and 517 participants developed dementia over 11 and 15 years of follow-up. Using multivariable cox proportional-hazards models, the hazard ratios for mild and moderate to severe visual impairment were 1.26 (95% Confidence Interval [CI] 0.92-1.72) and 2.16 (95% CI 1.37-3.40), in UK Biobank, and 1.05 (95% CI 0.72-1.53) and 1.93 (95% CI 1.05-3.56) in EPIC-Norfolk, compared to no visual impairment. When excluding participants censored within 5 years of follow-up or with prevalent poor or fair self-reported health, the direction of the associations remained similar for moderate impairment but were not statistically significant. Our findings suggest visual impairment might be a promising target for dementia prevention, however the possibility of reverse causation cannot be excluded.

Objective: Prediabetes has been suggested to increase mortality risk; however, the definitions of prediabetes that can predict mortality remain elusive. We prospectively investigated the association of multiple definitions of prediabetes with the risk of mortality from all-causes, cardiovascular disease (CVD), and cancer in Japanese workers. Research design and methods: The study included 62,785 workers who underwent a health checkup in 2010 or 2011 and were followed up for mortality from 2012 to March 2019. <a>Prediabetes was defined according to fasting plasma glucose (FPG) or glycated hemoglobin (HbA1c) level or a combination of both using the American Diabetes Association (ADA) or World Health Organization (WHO)/International Expert Committee (IEC) criteria. </a>The Cox proportional hazards regression model was used to investigate the associations. Results: Over a 7-year follow-up, 229 deaths were documented. <a>Compared with normoglycemia, prediabetes defined according to ADA criteria was associated with a higher risk of all-cause (hazard ratio [HR] 1.53; 95% confidence interval [CI] 1.12–2.09) and cancer (HR 2.37; 95% CI 1.45–3.89) mortality but not with CVD mortality. </a>The results were materially unchanged when prediabetes was defined according to ADA FPG, ADA HbA1c, WHO FPG, or combined WHO/IEC criteria. Diabetes was associated with the risk of all-cause, CVD, and cancer mortality. Conclusion: In a cohort of Japanese workers, FPG- and HbA1c-defined prediabetes according to ADA or WHO/IEC was each associated with a significantly increased risk of mortality from all-causes and cancer but not CVD.

AbstractWomen have a longer life expectancy than men in the general population. However, it has remained unclear whether this advantage is maintained in patients undergoing maintenance hemodialysis. The aim of this study was to compare the risk of mortality, especially infection-related mortality, between male and female hemodialysis patients. A total of 3065 Japanese hemodialysis patients aged ≥ 18 years old were followed up for 10 years. The primary outcomes were all-cause and infection-related mortality. The associations between sex and these outcomes were examined using Cox proportional hazards models. During the median follow-up of 8.8 years, 1498 patients died of any cause, 387 of whom died of infection. Compared with men, the multivariable-adjusted hazard ratios (95% confidence interval) for all-cause and infection-related mortality in women were 0.51 (0.45–0.58, P < 0.05) and 0.36 (0.27–0.47, P < 0.05), respectively. These findings remained significant even when propensity score-matching or inverse probability of treatment weighting adjustment methods were employed. Furthermore, even when the non-infection-related mortality was considered a competing risk, the infection-related mortality rate in women was still significantly lower than that in men. Regarding all-cause and infection-related deaths, women have a survival advantage compared with men among Japanese patients undergoing maintenance hemodialysis.

BackgroundA number of studies have demonstrated a J-shaped curve between blood pressure (BP) and all-cause mortality, but few studies have used longitudinal change in BP to study mortality in the Chinese population.MethodsWe performed a 30-year follow-up study to examine the association between BP (at baseline and longitudinal change) and risk of mortality in the Linxian General Population Trial Cohort. At baseline, a total of 29 584 healthy adults were enrolled in the Linxian General Population Trial in 1985 and followed through to the end of 2014. The final analysis was restricted to 29 439 participants (55% women) after exclusion of outliers. We also examined the potential effects of BP trajectory patterns during the period of 1985–1999 on sequent risk of mortality. Adjusted Cox proportional hazards models were used to estimate HRs and 95% CIs.ResultsCompared with participants with normal BP, patients with prehypertension, stage 1, stage 2 or stage 3 hypertension had an increased risk of all-cause mortality, with HRs of 1.09 (95% CI 1.05 to 1.14), 1.34 (95% CI 1.28 to 1.40), 1.69 (95% CI 1.60 to 1.79) and 2.14 (95% CI 2.01 to 2.28), respectively. Relative to stable BP of normotension, having a rise in BP from normotension to hypertension or from prehypertension to hypertension both conferred an increased risk of total and cardiovascular disease and stroke mortality (total: HRs 1.22 (95% CI 1.12 to 1.34) and 1.36 (95% CI 1.23 to 1.51); cardiovascular disease: HRs 1.42 (95% CI 1.17 to 1.73) and 1.55 (95% CI 1.24 to 1.93); stroke: HRs 2.29 (95% CI 1.88 to 2.80) and 2.61 (95% CI 2.11 to 3.24), respectively).ConclusionsThese findings emphasise that development of incident hypertension in middle age could increase the risk of total, cardiovascular disease and stroke mortality, and suggest that current BP targets could be revised.Trial registration numberNCT00342654;Post-results.

Abstract Context The patterns of associations between glycated Hb (HbA1c) and mortality are still unclear. Objective To explore the extent to which ranges of HbA1c levels are associated with the risk of mortality among participants with and without diabetes. Design, Setting, and Patients This was a nationwide, community-based prospective cohort study. Included were 15,869 participants (median age 64 years) of the Health and Retirement Study, with available HbA1c data and without a history of cancer. Cox proportional hazards regression models were used to estimate hazard ratios with 95% CIs for mortality. Results A total of 2133 participants died during a median follow-up of 5.8 years. In participants with diabetes, those with an HbA1c level of 6.5% were at the lowest risk of all-cause mortality. When HbA1c level was <5.6% or >7.4%, the increased all-cause mortality risk became statistically significant as compared with an HbA1c level of 6.5%. As for participants without diabetes, those with an HbA1c level of 5.4% were at the lowest risk of all-cause mortality. When the HbA1c level was <5.0%, the increased all-cause mortality risk became statistically significant as compared with an HbA1c level of 5.4%. However, we did not observe a statistically significant elevated risk of all-cause mortality above an HbA1c level of 5.4%. Conclusions A U-shaped and reverse J-shaped association for all-cause mortality was found among participants with and without diabetes. The corresponding optimal ranges for overall survival are predicted to be 5.6% and 7.4% and 5.0% and 6.5%, respectively.

Objective:To examine whether probable REM sleep behavior disorder (pRBD) was associated with increased risk of developing stroke in a community-based cohort.Methods:The study included 12,003 participants (mean age 54.0 years) of the Kailuan Study, free of stroke, cancer, Parkinson disease, dementia, and head injury at baseline (2012). We determined pRBD using a validated REM sleep behavior disorder (RBD) questionnaire in 2012. Incident stroke cases were confirmed by review of medical records. We used Cox proportional hazards models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of stroke according to pRBD status, adjusting for several sleep measures (i.e., insomnia, daytime sleepiness, sleep duration, snoring, and use of hypnotics) and other potential confounders.Results:During 3 years of follow-up, we documented 159 incident stroke cases. Relative to participants without pRBD at the baseline, those with pRBD had a 157% higher risk (95% CI 59%–313%) of developing stroke. Presence of pRBD was associated with increased risk of both stroke types—the adjusted HR was 1.93 (95% CI 1.07–3.46) for ischemic stroke and 6.61 (95% CI 2.27–19.27) for hemorrhagic stroke.Conclusions:Presence of pRBD was associated with a higher risk of developing stroke, including both ischemic and hemorrhagic types. Future studies with clinically confirmed RBD and a longer follow-up would be appropriate to further investigate this association.

Background. The study is aimed at exploring the relationship of platelet-to-lymphocyte (PLR), all-cause, and cardiovascular disease (CVD) mortality in peritoneal dialysis (PD) patients based on gender. Methods. A total of 1438 PD patients from January 1,2007 to December 31, 2014 in PD center at The First Affiliated Hospital, Sun Yat-sen University, were included. Patients were followed up until December 31, 2019. The endpoint was all-cause mortality and CVD mortality. Cox proportional hazards regression models were used to evaluate the association of PLR with all-cause and CVD mortality to calculate hazard ratios (HR) and 95% confidence intervals (CI). Results. After a median of 48.9 (interquartile range [IQR]: 23.4-79.3) months of follow-up, 406 (28.2%) patients died based on all-cause death, among which 200 (49.3%) patients died from CVD. In the multivariate Cox regression model, we found that PLR was independently related to an increased risk of CVD mortality only in female PD patients, with HR of 1.003 (95% CI: 1.001-1.006). Interaction test showed that the correlation between PLR level for all-cause and CVD mortality varied with gender ( p = 0.042 and p = 0.012 , respectively). Conclusion. Higher PLR was associated with a higher risk of CVD mortality in female PD patients.
