BackgroundLittle is known about the impacts of sleep duration and daytime napping on the risk of type 2 diabetes mellitus (T2DM).MethodsIn this study, 20,318 participants (7,597 men, 12,721 women) aged 40–79 years without a history of T2DM, stroke, coronary heart disease, or cancer at baseline (1988–1990), completed the baseline survey and the 5-year follow-up questionnaires, which included average sleep duration, napping habits, and self-reports of physician-diagnosed diabetes. The multivariable odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using a logistic regression model.ResultsDuring the 5-year follow-up, 531 new cases of T2DM (266 men and 265 women) were documented. Sleep duration ≥ 10 h was associated with higher risk of T2DM compared to sleep duration of 7 h (OR 1.99: 95%CI, 1.28–3.08). The excess risk was observed for both sexes and primarily found among the non-overweight; the multivariable ORs of sleeping ≥ 10 h compared to 7 h were 2.05 (1.26–3.35) for the non-overweight (BMI < 25 kg/m2) and 1.38 (0.49–3.83) for the overweight (BMI ≥ 25 kg/m2). The respective ORs of nappers vs non-nappers were 1.30 (1.03–1.63) and 0.92 (0.65–1.29). Among the non-overweight, nappers who slept ≥ 10 h had the highest risk of T2DM (OR 2.84: 95%CI, 1.57–5.14), non-nappers who slept ≥ 10 h (2.27: 1.27–4.06), and nappers who slept < 10 h (1.30: 1.03–1.64), compared with non-nappers who slept < 10 h.ConclusionsLong sleep duration was associated with the risk of T2DM in both sexes, which was confined to the non-overweight.

Background: The association between hobby engagement and risk of dementia reported from a short-term follow-up study for individuals aged ≥65 years may be liable to reverse causation. We examined the association between hobby engagement in age of 40-69 years and risk of dementia in a long-term follow-up study among Japanese including individuals in mid-life, when the majority of individuals have normal cognitive function.Methods: A total of 22,377 individuals aged 40–69 years completed a self-administered questionnaire in 1993–1994. The participants answered whether they had hobbies according to the three following responses: having no hobbies, having a hobby, and having many hobbies. Follow-up for incident disabling dementia was conducted with long-term care insurance data from 2006 to 2016.Results: During 11.0 years of median follow-up, 3,095 participants developed disabling dementia. Adjusting for the demographic, behavioral, and psychosocial factors, the multivariable hazard ratios (95% confidence intervals) of incident disabling dementia compared with “having no hobbies” were 0.82 (0.75–0.89) for “having a hobby” and 0.78 (0.67–0.91) for “having many hobbies”. The inverse association was similarly observed in both middle (40-64 years) and older ages (65-69 years). For disabling dementia subtypes, hobby engagement was inversely associated with the risk of dementia without a history of stroke (probably non-vascular type dementia), but not with that of post-stroke dementia (probably vascular type dementia).Conclusions: Hobby engagement in both mid-life and late-life was associated with a lower risk of disabling dementia without a history of stroke.

Background: An association between birth weight and cardiovascular disease (CVD) in adulthood has been observed in many countries; however, only a few studies have been conducted in Asian populations.Methods: We used data from the baseline survey (2011–2016) of the Japan Public Health Center-based Prospective Study for the Next Generation Cohort, which included 114,105 participants aged 40–74 years. Adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) were calculated from the prevalence of present and past histories of CVD and other lifestyle-related diseases, including hypertension, diabetes, hyperlipidemia, and gout, by birth weight, using Poisson regression.Results: The prevalence of CVD increased with lower birth weight, with the highest prevalence among those with birth weight under 1,500 grams (males 4.6%; females 1.7%) and the lowest one among those with birth weight at or over 4,000g (males 3.7%: females 0.8%). Among 88.653 participants (41,156 males and 47,497 females) with complete data on possible confounders, birth weight under 1,500g was associated with a higher prevalence of CVD (aPR 1.76 [95%CI 1.37-2.26]), hypertension (aPR 1.29 [95%CI 1.17–1.42]), and diabetes (aPR 1.53 [95%CI 1.26–1.86]) when a birth weight of 3,000–3,999 grams was used as the reference. Weaker associations were observed for birth weight of 1500–2499 grams and 2500–2999 grams, while no significant associations were observed for birth weight at or over 4000 g. The association between birth weight and the prevalence of hyperlipidemia was less profound, and no significant association was observed between birth weight and gout.Conclusion: Lower birth weight was associated with a higher prevalence of CVD, hypertension, and diabetes in the Japanese population.

Background: Associations of major risk factors for stroke with total and each type of stroke as well as subtypes of ischemic stroke and their population attributable fractions had not been examined comprehensively.Methods: Participants of the Japan Public Health Center-based prospective (JPHC) Study Cohort II without histories of cardiovascular disease and cancer (n=14,797) were followed from 1993 through 2012. Associations of current smoking, hypertension, diabetes, overweight (body mass index ≥ 25 kg/m2), non-high-density lipoprotein cholesterol (non-HDLC) categories, low HDLC (< 40 mg/dL), urine protein, and history of arrhythmia were examined in a mutually-adjusted Cox regression model that included age and sex. Population attributable fraction (PAF) was estimated using the hazard ratios and the prevalence of risk factors among cases.Results: Subjects with hypertension were 1.63 to 1.84 times more likely to develop any type of stroke. Diabetes, low HDLC, current smoking, overweight, urine protein, and arrhythmia were associated with risk of overall and ischemic stroke. Hypertension and urine protein were associated with risk of intracerebral hemorrhage while current smoking, hypertension, and low non-HDLC were associated with subarachnoid hemorrhage. Hypertension alone accounted for more than a quarter of stroke incidence, followed by current smoking and diabetes. High non-HDLC, current smoking, low HDLC, and overweight contributed mostly to large-artery occlusive stroke. Arrhythmia explained 13.2% of embolic stroke. Combined PAFs of all the modifiable risk factors for total, ischemic and large-artery occlusive strokes were 36.7 and 44.5% and 61.5%, respectively.Conclusion: Although there are differences according to the subtypes, hypertension could be regarded as the most crucial target for preventing strokes in Japan.

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: Helicobacter pylori (H. pylori) is an established causative factor of gastric cancer. Although the expansion of insurance coverage has led to an increase in the number of patients treated for H. pylori, the population impact of eradication treatment for H. pylori has been scarcely investigated. This study aimed to clarify the long-term responses of H. pylori antibody titer after eradication treatment using large scale cross-sectional data from the Japan Public Health Center-based Prospective Study for the Next Generation (JPHC-NEXT Study).Methods: A total of 55,282 Japanese participants aged 40 to 74 years residing in 16 areas provided blood samples from 2011 through 2016. From these, treated (n = 6,276) and untreated subjects who were seropositive for H. pylori or had serological atrophy (n = 22,420) formed the study population (n = 28,696). Seropositivity was defined as an anti-H. pylori IgG titer of ≥10 U/mL. Antibody level was compared among subjects according to self-reported treatment history as untreated, and treated for less than 1 year (<1Y), 1 through 5 years (1–5Y), and 6 or more years ago (6Y+).Results: Median serum antibody titer was 34.0 U/mL, 7.9 U/mL, 4.0 U/mL, and 2.9 U/mL for the untreated, <1Y, 1–5Y, and 6Y+ groups, respectively. While those treated for H. pylori within the previous year had a 76.8% lower antibody titer compared to untreated subjects, approximately 41% of subjects were still seropositive.Conclusion: A significant reduction in H. pylori antibody titer occurs within 1 year after eradication treatment, but that a long period is needed to achieve complete negative conversion.

Aim: Seaweed is a popular traditional foodstuff in Asian countries. To our knowledge, few studies have examined the association of seaweed intake with mortality from cardiovascular disease. We examined the association of frequency of seaweed intake with total and specific cardiovascular disease mortality. Methods: We examined the association of seaweed intake with mortality from cardiovascular disease among 40,234 men and 55,981 women who participated in the Japan Collaborative Cohort Study for Evaluation of Cancer Risk. Sex-specific hazard ratios for mortality from cardiovascular disease (stroke, stroke subtypes, and coronary heart disease) according to the frequency of seaweed intake were calculated stratified by study area and adjusted for potential cardiovascular risk factors and dietary factors. Results: During the 1,580,996 person-year follow-up, 6,525 cardiovascular deaths occurred, of which 2,820 were due to stroke, and 1,378, to coronary heart disease. Among men, the multivariable analysis showed that participants who ate seaweed almost every day compared with those who never ate seaweed had hazard ratios (95% confidence interval; P for trend) of 0.79 (0.62–1.01; 0.72) for total cardiovascular disease, 0.70 (0.49–0.99; 0.47) for total stroke, 0.69 (0.41–1.16; 0.11) for cerebral infarction. Among women, the multivariable-adjusted hazard ratios were 0.72 (0.55–0.95; 0.001) for total cardiovascular disease, 0.70 (0.46–1.06; 0.01) for total stroke, and 0.49 (0.27–0.90; 0.22) for cerebral infarction. No associations were observed between seaweed intake and risk of intraparenchymal hemorrhage and coronary heart disease among either men or women. Conclusions: We found an inverse association between seaweed intake and cardiovascular mortality among Japanese men and women, especially that from cerebral infarction.

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.

Aims: We examined whether secondhand smoke exposure in childhood affects the risk of coronary heart disease (CHD) in adulthood. Methods: In the Japan Collaborative Cohort Study, we analyzed data on 71,459 participants aged 40-79 years, with no history of CHD, stroke, or cancer at baseline (1988-1990) and who completed a lifestyle questionnaire including the number of smoking family members in childhood (0, 1, 2, and 3+ members) and followed them up until the end of 2009. The Cox proportional hazards model was used to calculate the multivariable hazard ratios (HRs) with 95% confidence intervals (CIs) of CHD mortality according to the number of smoking family members in childhood. Results: During the median 18.9 years' follow-up, 955 CHD deaths were reported. There was a dose-response relationship between the number of smoking family members at home and CHD mortality among middle-aged individuals (40-59 years); the multivariable HRs (95% CIs) were 1.08 (0.76-1.54) for 1, 1.35 (0.87-2.08) for 2, and 2.49 (1.24-5.00) for 3+ smoking family members compared with 0 members (p for trend=0.03). The association for 3+ smoking family members among the middle-aged group was more evident in men than in women (the multivariable HRs [95% CIs] were 2.97 [1.34-6.58] and 1.65 [0.36-7.52], respectively) and more evident in non-current smokers than in current smokers (the multivariable HRs [95% CIs] were 4.24 [1.57-11.45]and 1.93 [0.72-5.15], respectively). Conclusions: Secondhand smoke exposure in childhood was associated with an increased risk of CHD mortality in adulthood, primarily in middle-aged men and non-current smokers.

Aim: Manganese (Mn) is an essential element in the human body, and it has a significant impact on cardiovascular risk factors such as diabetes, blood pressure, and cholesterol levels. However, no research has been conducted on the association between Mn and cardiovascular disease (CVD), to the best of our knowledge. This study thus examined the association between dietary Mn intake and CVD mortality in the general Japanese population.Methods: The CVD mortality among 58,782 participants from the Japan Collaborative Cohort Study (JACC) aged 40–79 years was determined during a median follow-up period of 16.5 years. The Mn intake was estimated using a food frequency questionnaire at the baseline (1989–1990), and multivariate-adjusted hazard ratios (HRs) for mortality were computed according to quintiles of energy-adjusted Mn intake. Results: During the follow-up period, a total of 3408 CVD deaths were recorded. Participants in the highest quintile of Mn intake had a lower risk of mortality from total stroke (HR:95% CI, 0.76: 0.64–0.90), ischemic stroke (HR: 0.77, 0.61–0.97), ischemic heart disease (HR: 0.76, 0.58–0.98), and total CVD (HR: 0.86, 0.76–0.96) compared with those in the lowest quintile. The reduced risk of mortality from intraparenchymal hemorrhage with high Mn intake was observed among women (HR: 0.60, 0.37–0.96) but not men (HR: 0.93, 0.59–1.47). The observed associations were more robust in postmenopausal than in premenopausal women. Conclusions: Our study is the first to show the prospective association between dietary Mn intake and reduced risk of mortality from CVD in the Japanese population.

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.

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.
