Aims The control of blood glucose levels, pressure (BP), and low-density lipoprotein cholesterol (LDL-C) levels reduces the risk diabetes complications; however, data are scarce on status these factors among workers with diabetes. present study aimed to estimate prevalence participants who meet glycated hemoglobin (HbA1c), BP, LDL-C recommendations, investigate correlates poor glycemic in a large working population Japan. Methods Japan Epidemiology Collaboration Occupational Health (J-ECOH)...
We aimed to determine the prospective association of smoking status, intensity, and cessation with risk hearing loss in a large Japanese cohort.The cohort study included 50195 employees, who were aged 20-64 years free at baseline. Participants followed up for maximum 8 years. Pure-tone audiometric testing was performed annually identify 1 4 kHz. Cox proportional hazards regression models used investigate between loss.During follow-up, 3532 individuals developed high-frequency loss, 1575...
Objective Risk models and scores have been developed to predict incidence of type 2 diabetes in Western populations, but their performance may differ when applied non-Western populations. We validated a risk score for predicting 3-year Japanese population. Methods Participants were 37,416 men women, aged 30 or older, who received periodic health checkup 2008–2009 eight companies. Diabetes was defined as fasting plasma glucose (FPG) ≥126 mg/dl, random ≥200 glycated hemoglobin (HbA1c) ≥6.5%,...
Prediabetes has been suggested to increase risk for death; however, the definitions of prediabetes that can predict death remain elusive. We prospectively investigated association multiple with from all causes, cardiovascular disease (CVD), and cancer in Japanese workers.The study included 62,785 workers who underwent a health checkup 2010 or 2011 were followed up 2012 March 2019. was defined according fasting plasma glucose (FPG) glycated hemoglobin (HbA1c) values combination both using...
Aims To examine the association of smoking status, intensity, and cessation with risk type 2 diabetes (T2D) using a large database. Methods The present study included 53,930 Japanese employees, aged 15 to 83 years, who received health check-up did not have at baseline. Diabetes was defined as fasting plasma glucose ≥126 mg/dl, random ≥200 HbA1c ≥6.5% (≥48 mmol/mol), or receiving medication for diabetes. Cox proportional-hazards regression models were used investigate between Results During...
We sought to establish the optimal waist circumference (WC) cut-off point for predicting diabetes mellitus (DM) and compare predictive ability of metabolic syndrome (MetS) criteria Joint Interim Statement (JIS) Japanese Committee Criteria MetS (JCCMS) DM in Japanese. Participants Japan Epidemiology Collaboration on Occupational Health Study, who were aged 20–69 years free at baseline (n = 54,980), followed-up a maximum 6 years. Time-dependent receiver operating characteristic analysis was...
Objective Working long hours is a potential health hazard. Although self‐reporting of working in various time frames has been used epidemiologic studies, its validity unclear. The objective this study was to examine the and reproducibility self‐reported among Japanese male employees. Methods participants were 164 employees four large‐scale companies Japan. For validity, Spearman correlation between second survey recorded by company calculated for following frames: daily hours, monthly...
Background: Waist-to-height ratio (WHtR) has been suggested as a better screening tool than body mass index (BMI) and waist circumference (WC) for assessing cardiometabolic risk. However, most previous studies did not consider age. Methods Results: Participants were 45,618 men 8,092 women aged 15–84 years who received periodic health checkups in 9 companies Japan. Clustering of risk factors was defined by the existence 2 or more high blood pressure, hyperglycemia, dyslipidemia. In both...
The effect of smoking on mortality in working-age adults remains unclear. Accordingly, we compared the effects cigarette and cessation total cause-specific a Japanese working population.
The effect of weight gain following smoking cessation on cardiovascular risks is unclear. We aimed to prospectively investigate the association with trajectory estimated coronary heart disease (CHD).In a cohort 18 562 Japanese male employees aged 30-64 years and initially free diseases, participants were exclusively grouped into sustained smokers, quitters (body increase ≥5%), without <5% or loss), never smokers. Global 10-year CHD risk was annually by using well-validated prediction model...
We examined a prospective association between serum creatinine levels and diabetes.The present study included 31,343 male workers without diabetes, aged 20 64 years at baseline. calculated the cumulative average of their over period. defined diabetes as either glycated hemoglobin ≥6.5%, random glucose ≥200 mg/dL, fasting ≥126 mg/dL or receiving antidiabetic treatment. Cox proportional hazards regression analysis was carried out to estimate hazard ratio (HR) 95% confidence interval (CI).With...
The present study aimed to estimate cumulative incidence of overweight and obesity describe 5-year longitudinal changes in body mass index (BMI) a large occupational cohort Japan.Participants were 55 229 Japanese employees, who aged 20-59 years attended at all subsequent annual health check-ups between 2009 2014. Mixed model analysis was performed examine the effects age by gender on BMI change, with as random variable. Cumulative (23.0≤ <27.5 kg/m2 ) (BMI ≥27.5 calculated. Logistic...
Long-term sick-leave is a major public health problem, but data on its incidence in Japan are scarce. We aimed to present reference for long-term among private sector employees Japan.The study population comprised of 12 companies that participated the Epidemiology Collaboration Occupational Health Study. Details medically certified lasting ≥30 days were collected from each company. Age- and sex-specific rate was calculated period April 2012 March 2014.A total 1422 spells men 289 women...
We prospectively examined the association of diabetes risk with number metabolic abnormalities, as well their combinations, according to presence or absence impaired fasting glucose (IFG) in a large-scale Japanese working population.Participants included 55,271 workers at 11 companies who received periodic health check-ups between 2008 and 2013. The syndrome (MetS) components were defined using 2009 Joint Interim Statement. IFG was plasma 5.6-6.9 mmol/L. Diabetes newly diagnosed after...
To investigate trajectories of body mass index (BMI) and waist circumference (WC) among prediabetic people who progressed to diabetes, remained with prediabetes, those returned normoglycemia.We used data from 22,945 received an annual health checkup for up eight years. The development diabetes was defined using the American Diabetes Association criteria. People did not progress during observation period were classified as 'remained prediabetes' or 'returned normoglycemia', based on their...
Aims: We aimed to investigate the association between non-high-density lipoprotein cholesterol (non-HDL-C) levels and risk of cardiovascular disease (CVD) its subtypes.
Abstract The 250‐m Choshi core (CHOSHI‐1), drilled from hemipelagic muds of the Inubo Group, has been physically, geochemically and tephrochronologically analyzed back to 1 Ma. We provide pollen results for 19–169 m section (400–780 ka) bracketed by marker tephra Ty1 (equivalent J4) Brunhes–Matuyama paleomagnetic boundary. show good agreement with corresponding oxygen isotope (δ 18 O) profile, high δ O intervals dominated boreal conifers Picea , Abies Pinus (subgen.
