Psychosocial factors are independent risk factors for the development of Type 2 diabetes in Japanese workers with impaired fasting glucose and/or impaired glucose tolerance,

DIABETIC MEDICINE, Issue 10 2008

Abstract Aims, We prospectively studied Japanese workers with impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT) and analysed possible risk factors for diabetes, including psychosocial factors such as stress. Methods, The participants were 128 male Japanese company employees (mean age, 49.3 ± 5.9 years) with IFG and/or IGT diagnosed by oral glucose tolerance test (OGTT). Participants were prospectively studied for 5 years with annual OGTTs. The Kaplan,Meier method and Cox's proportional hazard model were used to analyse the incidence of diabetes and the factors affecting glucose tolerance, including anthropometric, biochemical and social,psychological factors. Results, Of 128 participants, 36 (28.1%) developed diabetes and 39 (30.5%) returned to normal glucose tolerance (NGT) during a mean follow-up of 3.2 years. Independent risk factors for diabetes were night duty [hazard ratio (HR) = 5.48, P = 0.002], higher fasting plasma glucose (FPG) levels within 6.1,6.9 mmol/l (HR = 1.05, P = 0.031), stress (HR = 3.81, P = 0.037) and administrative position (HR = 12.70, P = 0.045), while independent factors associated with recovery were lower FPG levels (HR = 0.94, P = 0.017), being a white-collar worker (HR = 0.34, P = 0.033), non-smoking (HR = 0.31, P = 0.040) and lower serum alanine aminotransferase (ALT) levels (HR = 0.97, P = 0.042). Conclusions, In addition to FPG levels at baseline, psychosocial factors (night duty, stress and administrative position) are risk factors for Type 2 diabetes, while being a white-collar worker, a non-smoker and lower serum ALT levels are factors associated with return to NGT in Japanese workers with IFG and/or IGT.

Lower urinary tract symptoms in relation to lifestyle and medical conditions in Japanese workers

INTERNATIONAL JOURNAL OF UROLOGY, Issue 5 2009
Kentaro Tomita
Objectives: To examine the association of medical conditions and lifestyle with lower urinary tract symptoms (LUTS) in a population of Japanese male workers. Methods: A questionnaire survey on LUTS was conducted at the time of a periodic health examination among workers of a group of engineering and shipbuilding companies in Southern Kanto, Japan. A total of 1278 (85%) men responded. LUTS were assessed by using a modified International Prostate Symptom Score questionnaire. Men having at least one point of the score were regarded as positive. Logistic regression analysis was used to examine the relation of the LUTS to age, smoking, drinking, body mass index, and medical treatment of diabetes mellitus, hypertension, and dyslipidemia. Results: Age was a strong determinant of LUTS. Men undergoing medical treatment for diabetes mellitus were significantly more likely to have LUTS than men without treatment (multivariate-adjusted odds ratio, 1.8; 95% confidence interval, 1.0,3.2). Increased odds of LUTS were also observed in men undergoing medical treatment for hypertension or dyslipidemia. Smoking, drinking alcohol, and obesity were not related to LUTS. Conclusions: Our present findings, together with previous epidemiological and experimental evidence, suggest that LUTS might share common etiological factors with diabetes mellitus, hypertension, and dyslipidemia.

Validity of the Center for Epidemiologic Studies Depression Scale as a screening instrument of major depressive disorder among Japanese workers

AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 1 2007
Koji Wada MD
Abstract Background The Center for Epidemiologic Studies Depression Scale (CES-D) is used at workplaces to screen depressive disorders. The aim of this study was to examine the validity of the CES-D for depression in a workplace. Methods The CES-D was administered to 2,219 workers (84.2% men; age 21,68 years) at a manufacturing company in Japan. Concomitantly all workers had an interview with the Mini International Neuropsychiatric Interview (MINI) as a gold standard for diagnosing major depressive disorder (MDD). The validity was evaluated by a receiver operating characteristic (ROC) curve. Results The area under the ROC curve of the CES-D was 0.96 [95% Confidence Interval (CI): 0.94,0.99]. The optimal cut-off score of MDD was 19 for screening. Conclusions The validity of CES-D is confirmed and it is a valid instrument for detecting MDD in working populations in Japan. Am. J. Ind.

Is DSM widely accepted by Japanese clinicians?

PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 5 2001
Toshiyuki Someya MD
Abstract The Diagnostic and Statistical Manual of Mental Disorders, 3rd edition (DSM-III), a new standardized diagnostic system with multiaxial diagnosis, operational criteria and renewed definitions of mental disorders, was introduced in 1980 and prompted movements to reform conventions in Japanese psychiatry. This review overviews the initial response of Japanese clinicians to accept DSM-III, and its effects on the development of systematic research of psychiatric diagnosis. These new research activities include those on reliability of psychiatric diagnosis, application of various evaluation tools, discussion on the concept of mental disorders, relation of personality disorders with depressive disorders, and Taijin-kyofusho, or culturally distinctive phobia in Japan. A reference database search to survey the latest trend on psychiatric research indicated that the number of papers published by Japanese workers increased sharply after 1987, and DSM apparently greatly influenced their internationalization. Twenty years after the publication of DSM-III, a questionnaire on the use of DSM-IV was set out in 2000 to survey how widely DSM is utilized in clinical practice in Japan. Two hundred and twelve psychiatrists answered the questionnaire, and the results show that DSM has been accepted positively by the younger generation, while the older generation (over 40s) has still less interest in DSM, and DSM is used mainly for research purposes rather than in daily practice.

Relationship between body mass index and infertility in healthy male Japanese workers: a pilot study

ANDROLOGIA, Issue 2 2009
K. Ohwaki
Summary Our aim was to evaluate the relationship between men's body mass index (BMI) and infertility and to examine the effects of factors related to metabolic syndrome such as hypertension, dyslipidaemia, and impaired glucose tolerance. Our sample comprised 74 healthy Japanese workers at a company who were married between 2003 and 2005. The outcome variable was whether a baby was born during the study period (median follow-up period, 20 months; range, 8,42 months). Data for BMI and other factors were obtained from the results of an annual health checkup in the year of each employee's marriage. Forty-seven men (64%) did not father a baby. Having a baby was significantly associated with a low BMI (21.4 versus 23.2 kg m,2; P = 0.006). A Cox proportional hazard regression model was performed to assess the association of BMI with fathering a baby. Adjusting for age, systolic and diastolic blood pressure, low density lipoprotein cholesterol, triglycerides, and haemoglobin A1C, higher BMI was significantly associated with not fathering a baby (hazard ratio, 0.80; 95% confidence interval, 0.67,0.95; P = 0012). High BMI in men was independently associated with an increased risk of not siring a child. [source]
