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...
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...
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.
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...
This paper presents a method of human body communication that employs magnetic coupling. Since acts as one component loop for creating the coupling, strong coupling occurs only when person closes loop. Thus, person's natural bodily movement forms channel. Here, validation mechanism channel formation and robustness against surrounding environment were presented. First, validity circuit model was demonstrated through measurement transfer function (channel loss) at frequencies up to 20 MHz....
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...
The recent development of wearable devices has enabled easy and continuous measurement heart rate (HR). Exercise intensity can be calculated from HR with indices such as percent reserve (%HRR); however, this requires an accurate resting HR, which time-consuming. use during sleep may a substitute that considers the calibration-less %HRR. This study examined validity %HRR on in comparison to oxygen consumption (%VO2R) gold standard. Additionally, 24/7%HRR using method is demonstrated.Twelve...
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...
A key skill in archery is the ability to suppress postural tremor while aiming at a target. Providing feedback during daily practice potentially effective way of suppressing tremor. However, subtle and difficult measure using vision-based techniques. This article proposes method that uses bow equipped with small, lightweight acceleration sensor. First, we automatically detect an archer's shooting execution cycle, including aiming, release, follow-through phases, by binary classification,...
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.
and NTT DOCOMO have begun trials on patient rehabilitation support using the functional material called "hitoe," which can take continuous measurements of biological data simply by having patients wear it.As innovation progresses in medical nursing care, it is necessary to improve quality rehabilitation, especially for elderly patients, recovery progress return daily life, preventing recurrence debilitation.This article introduces new initiatives develop wearable technology light these social issues.
Data are limited on the sex-specific prevalence of diseases and their risk factors in middle-aged older workers Japan. In this cross-sectional study, we investigated age- hypertension, diabetes, dyslipidemia, metabolic syndrome (defined using joint statement criteria), obesity, underweight, abdominal smoking among approximately 70,000 to 90,000 Japanese (predominantly men) aged 20-69 years 2014. We also low cardiorespiratory fitness 2012 no leisure-time exercise both sexes, lifestyle-related...
Acceleration sensors are widely used in consumer wearable devices and smartphones. Postures estimated from recorded accelerations commonly as features indicating the activities of patients medical studies. However, recording for over 24 h is more likely to result data losses than a few hours, especially when consumer-grade used. Here, impute postures period h, we propose an imputation method that uses ensemble averaging. This outputs time series with less lost by calculating ratios taken at...
Abstract The purposes of the present study were: (1) to investigate relationship between hospital-associated functional decline (HAFD) and non-lying time (2) clarify optimal cut-off value for associated with HAFD in older patients undergoing transcatheter aortic valve implantation (TAVI). From January 2021 December 2022, admitted a university hospital who underwent trans-femoral TAVI were consecutively recruited. We measured short physical performance battery (SPPB) pre post-TAVI, from...
We previously developed a 3-year diabetes risk score in the working population. The objective of present study was to develop and validate flexible models that can predict for any arbitrary time-point during 7 years.
With the aim of developing potential high theoretical capacity Si as a negative electrode material for Li-ion batteries, new type composite current collector in which multi-walled carbon nanotubes (MWCNTs) are immobilized on Cu surface was developed using an electroplating technique. For with flat-Cu substrate, voltage plateaus related to stepwise electrochemical lithiation were observed below 0.27 V (vs. Li/Li+), whereas Cu/MWCNT substrate distinctly decreased overvoltage enhance...
We aimed to compare the association of body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR) with risk cardiovascular disease (CVD) among middle-aged working Japanese men.A nested case-control study was performed male employees who underwent periodic health checkup. A total 241 CVD cases were identified matched individually on age, gender, worksite 1205 controls. Data BMI, WC, WHtR, smoking, hypertension, diabetes, dyslipidemia collected at 4 years before...
Objective In contrast to the association between excess weight and sickness absence (SA), in relation underweight has been under‐researched. This study aimed examine effects of BMI at both extremes its distribution on SA. Methods Data came from Japan Epidemiology Collaboration Occupational Health 77,760 workers aged 20 59 years (66,166 males, 11,594 females). Information was collected medically certified long‐term SA (LTSA) (i.e., lasting ≥ 30 consecutive days) April 2012 March 2017. A...
An adaptive Kalman filter-based fusion algorithm capable of estimating respiration rate for unobtrusive respiratory monitoring is proposed. Using both signal characteristics and a priori information, the filter adaptively optimized to improve accuracy. Furthermore, system able combine respiration-related signals extracted from textile ECG sensor an accelerometer create single robust measurement. We measured derived rates and, when compared reference, found root-mean-square error 2.11...
