Aims: The evidence for the impact of alcohol consumption on long-term mortality among myocardial infarction (MI) survivors was limited. We aimed to examine whether alcohol consumption was associated with cause-specific and all-cause mortality in men with or without a history of MI. Methods: A total of 32,004 men aged 40-79 years with no history of MI and 1,137 male MI survivors, free of stroke and cancer, were followed through the end of 2009. Alcohol consumption was assessed using self-administered questionnaires at baseline and five years. Results: In MI survivors, consuming 23-45 g/day of alcohol was associated with a lower risk of coronary heart disease (CHD) mortality compared to never drinkers: the multivariable hazard ratio was 0.36 (95% confidence interval: 0.16-0.80). In non-MI men, a 10-26% lower risk was observed at <23 or 23-45 g/day with the U-shaped association for CHD, cardiovascular disease, other causes, and all causes (P-quadratic <0.001). Conclusion: Alcohol consumption of 23-45 g/day was associated with a lower CHD mortality in MI survivors as so in men without MI.

Background:The effect of postprandial glucose on the risk of cardiovascular disease has been emphasized, but it is controversial whether nonfasting glucose is related to incident stroke and its types.Methods and Results:We investigated the associations of nonfasting glucose with incident stroke and its types among 7,198 participants aged 40–74 years from the Circulatory Risk in Communities Study, enrolled in 1995–2000. We estimated multivariable hazard ratios (HR) using Cox proportional hazard models. Over a median follow-up of 14.1 years, 291 cases of total stroke (ischemic strokes: 191 including 109 lacunar infarctions) were identified. Nonfasting glucose concentration was associated with greater risk of incident total stroke, ischemic stroke and lacunar infarction when modeled categorically (for prediabetic type: 7.8–11.0 mmol/L vs. normal type: <7.8 mmol/L among all subjects, HR for lacunar infarction was 2.02, 95% confidence interval (CI): 1.19, 3.43) or continuously (per one standard deviation increment among all subjects, HR for lacunar infarction was 1.29, 95% CI: 1.15, 1.45). Diabetic type showed similar results. Population attributable fractions of nonfasting hyperglycemia were 13.2% for ischemic stroke and 17.4% for lacunar infarction.Conclusions:Nonfasting glucose concentration, either as a diagnosis of prediabetic and diabetic types or as a continuous variable, proved to be an independent predictor significantly attributed to incident total stroke, especially ischemic stroke and lacunar infarction, in the general population.

Background: The 2011 Great East Japan Earthquake has resulted in a nuclear accident, forcing residents of the surrounding areas to evacuate. To determine any association between excessive drinking and hypertension in the setting of disaster, we assessed whether the proportion of excessive drinkers increased and if post-disaster excessive drinking was a risk factor for hypertension.Methods: This retrospective study assessed data from the Japanese National Database. Cumulative population data for Fukushima Prefecture (3,497,576 people) were analyzed by categorizing residents into four areas—evacuation, coastal, central, and mountainous—to calculate the proportion of excessive, heavy (equivalent to binge drinking), and at-risk drinkers for 2008–2017. The hazard ratios (HRs) for the incidence of hypertension for 2012–2017 were examined in association with changes in drinking status pre- and post-disaster, which included 136,404 people who received specific health checkups pre-disaster (2008–2010) and post-disaster (2011–2012).Results: The proportion of excessive drinkers among women increased after the disaster in all areas examined. The association between excessive drinking and the incidence of hypertension was determined among men and women in all areas; it was stronger among women in the evacuation areas, with the sex- and age-adjusted HRs for the incidence of hypertension of 1.41 for pre-disaster excessive drinking, 2.34 for post-disaster excessive drinking, and 3.98 for pre- and post-disaster excessive drinking, compared with not excessive drinking pre- and post-disaster.Conclusion: Excessive drinking post-disaster may be associated with an increased risk of hypertension among men and women, especially among women in the evacuation areas.

Aim: We aimed to examine sex-specific risk factors for hyperuricemia or gout in Japanese cohorts. Methods: We followed up 3,188 men (mean age, 55.6 years) and 6,346 women (mean age, 54.1 years) without hyperuricemia, gout, or elevated liver enzymes at baseline from 1986 to 1990 for a median of 14.6 years. The participants were considered as having hyperuricemia or gout if their serum uric acid levels were ≥ 7.0 mg/dL or they were receiving treatment for hyperuricemia or gout during annual health checkups. The sex-specific multivariable hazard ratios (HRs) of hyperuricemia or gout incidence were calculated after adjustment for smoking and drinking status, body mass index, hypertension, diabetes, hypercholesterolemia, and hypertriglyceridemia using the Cox proportional-hazard model. Results: During follow-up, 733 men and 355 women had hyperuricemia or gout. Among men, the multivariable HRs (95% confidence intervals) of hyperuricemia or gout were 1.23 (1.00–1.52) and 1.41 (1.13–1.75) for drinkers of <46 and ≥ 46 g ethanol/day, respectively, compared with non-drinkers; 1.00 (0.81–1.24) and 1.18 (0.93–1.50) for smokers of 1–19 and ≥ 20 cigarettes/day, respectively, compared with never smokers; and 1.41 (1.20–1.65) for hypertensive compared with non-hypertensive participants. The HRs for women were 1.02 (0.70–1.48), 1.66 (1.05–2.63), and 1.12 (0.88–1.42) for current drinkers, current smokers, and hypertensive participants, respectively. For both men and women, body mass index, diabetes, hypercholesterolemia, and hypertriglyceridemia were not associated with hyperuricemia or gout incidence. Conclusions: Hypertension and alcohol drinking are risk factors for hyperuricemia or gout among men and smoking among women.

Background: The impact of body mass index on incidence of herpes zoster is unclear. This study investigated whether body mass index was associated with a history of herpes zoster and incidence during a 3-year follow-up, using data from a prospective cohort study in Japan.Methods: In total, 12,311 individuals were included in the cross-sectional analysis at baseline, of whom 1,818 with a history of herpes zoster were excluded from the incidence analysis, leaving 10,493 individuals. Body mass index (kg/m2) was classified into three categories (underweight: <18.5; normal: 18.5 to <25; and overweight: ≥25). To evaluate the risk of herpes zoster, we used a logistic regression model for prevalence and a Cox proportional hazard regression model for incidence.Results: Being overweight or underweight was not associated with herpes zoster prevalence at baseline. The multivariate hazard ratios of herpes zoster incidence for overweight versus normal-weight groups were 0.67 (95% confidence interval, 0.51–0.90) in all participants, and 0.57 (95% confidence interval, 0.39–0.83) in women, with no significant difference for men.Conclusion: Being overweight was associated with a lower incidence of herpes zoster than being normal weight in older Japanese women.

Aim: This study aimed to investigate the association between the serum high-sensitivity C-reactive protein (hs-CRP) levels and incident atrial fibrillation risk in the general Japanese population, who have lower hs-CRP levels than the Western population, and assess whether the association is modified by sex, overweight, hypertension, and smoking status. Methods: We conducted a prospective study in 6517 Japanese men and women aged 40–79 years without atrial fibrillation at baseline and enrolled in the Circulatory Risk in Communities Study (2002–2008). The hs-CRP levels were measured using the latex particle-enhanced immunonephelometric assay. Atrial fibrillation was identified using standard 12-lead electrocardiograms and information on physician-diagnosed atrial fibrillation history from the follow-up surveys. We used a Cox proportional hazard regression stratified by community. Results: During a median follow-up of 11 years, 127 new cases of atrial fibrillation (74 and 53 cases among men and women, respectively) were found. Compared to the lowest quintile of hs-CRP levels, the multivariable hazard ratios (95% confidence intervals) were 2.54 (1.17–5.50), 2.28 (1.06–4.93), 2.92 (1.37–6.23), and 2.77 (1.30–5.91) for the second, third, fourth, and fifth (highest) quintiles, respectively. There was no significant effect modification by sex, overweight, hypertension, and smoking status (P for interaction >0.05). Conclusions: Elevated hs-CRP levels were significantly associated with increased risk of atrial fibrillation in the Japanese population. The association of hs-CRP levels with incident atrial fibrillation did not vary according to sex, overweight, hypertension status, or smoking status.

Aim: N-terminal pro-B-type natriuretic peptide (NT-proBNP), frequently used as a biochemical marker for detecting and monitoring heart failure, is also a risk marker for development of coronary heart disease and total stroke. However, studies that explore subtypes of ischemic stroke with regard to NT-proBNP are scarce. Here, we examined NT-proBNP and its impact upon subtypes of ischemic stroke (lacunar stroke, large-artery occlusive stroke and embolic stroke) among Japanese. Methods: We measured NT-proBNP and categorized 4,393 participants of the Circulatory Risk in Communities Study into four groups (<55, 55-124, 125-399, and ≥ 400 pg/ml). We used a multivariable Cox proportional hazards model to examine association with risks of stroke and subtypes. Results: During 4.7 years of follow-up, we identified 50 strokes, including 35 ischemic (15 lacunar, 6 largeartery occlusive, 10 embolic strokes) and 14 hemorrhagic strokes. NT-proBNP was associated with stroke risk: the multivariable hazard ratio of total strokes was 7.29 (2.82-18.9) for the highest and 2.78 (1.25-6.16) for the second highest NT-proBNP groups compared with the lowest group. The respective hazard ratios for the highest NT-proBNP group were 9.37 (3.14–28.0) for ischemic stroke and 6.81 (1.11–41.7) for lacunar stroke. Further adjustment for atrial fibrillation did not attenuate these associations. The associations were similarly observed for large-artery occlusive and embolic strokes. Conclusion: We found that even moderate serum levels of NT-proBNP were associated with the risk of total and ischemic strokes among Japanese whose NT-proBNP levels were relatively low compared with Westerners.

Background: Although underweight young women are targets for interventions to prevent low bone mineral density (BMD), the relationship between change in body mass index (BMI) from youth to older age and BMD has not been widely investigated in community dwellers.Methods: In 749 healthy Japanese women aged 40–74 years, BMD was measured by quantitative ultrasound and anthropometric measurements, and BMI was calculated from body weight and height. The BMI of participants at age 20 years was estimated by self-reported body weight and their present height. They were classified into four groups according to the presence of underweight (BMI <18.5 kg/m2) at 20 and/or at present. Logistic regression models were used to estimate multivariate-adjusted odds ratios (ORs) of the presence of underweight at 20 and/or at present for osteopenia (BMD T score <−1 standard deviations) compared with participants with BMI ≥18.5 kg/m2 both at 20 and at present.Results: The participants who were underweight both at 20 and at present had a higher OR for osteopenia compared with those with BMI ≥18.5 kg/m2 at 20 and at present (OR 3.94; 95% confidence interval [CI], 1.97–7.89). Those underweight only at present also had significantly increased OR of developing osteopenia (OR 2.95; 95% CI, 1.67–5.24). The OR of those underweight only at 20 was 0.87 (95% CI, 0.51–1.48).Conclusions: Current underweight was associated with increased risk for osteopenia among Japanese women, especially in those who were underweight both at 20 and at present. To prevent low BMD in the future, maintaining appropriate body weight might be effective for young underweight women.

Aims: The frequency of breakfast intake has been reported to be inversely associated with the risk of cardiovascular events; however, it is uncertain what the impact of the energy and nutrient intakes from breakfast are. We assessed the association between these intakes from breakfast and the risk of stroke prospectively.Methods: In a baseline survey of four Japanese communities between 1981 and 1990, we enrolled 3 248 residents (1 662 men and 1 586 women) aged 40–59 years who were free from stroke and heart disease and who responded to the 24-hour dietary recall survey. We assessed the dietary intake at breakfast, lunch, dinner, and other times separately.Results: During the median 25-year follow-up, 230 individuals (147 men and 83 women) developed stroke. After adjustment for age, community, other dietary intakes, and lifestyle and physiological factors, the multivariable-adjusted hazard ratios (95% confidence intervals) of intracerebral hemorrhage for the highest versus lowest quartiles of energy intake from breakfast were 0.38 (0.15–0.99) in men and 1.36 (0.36–5.10) in women. For the major nutrients, a higher saturated or monounsaturated fat intake at breakfast was associated with a reduced risk of intracerebral hemorrhage in men, and remained statistically significant after further adjustment for intake of other major nutrients from breakfast.Conclusions: A higher intake of energy from breakfast, primarily saturated or monounsaturated fat, was associated with a reduced risk of intracerebral hemorrhage in Japanese men.
