OBJECTIVE The aim of this study was to assess prevalence, incidence, and persistence of carpal tunnel syndrome (CTS) and associated symptoms over a one-year period in a working population. METHODS We conducted a one-year prospective study of 418 active workers in 12 worksites. Detailed health interviews, psychosocial questionnaires, and(More)
To assess the geographical patterns of end-stage renal disease (ESRD) incidence and to identify the risk factors on the regional differences, the authors conducted an ecological study on incidence of ESRD and related risk factors in the 46 counties of South Carolina (SC). Age and gender adjusted, race specific incidence rates for each county in SC were(More)
Introduction Questionnaires that measure functional status such as the Disability of the Arm, Shoulder and Hand (QuickDASH) and the Medical Outcomes Study 12-item Short-Form Health Survey (SF-12) can quantify the impact of health on performance. Little is known about whether these questionnaires can be used as a tool for measuring disabilities among(More)
The risk of hypertension and related target organ damage is much greater in African Americans than in Caucasians. The risk of hypertensive end-stage renal disease is approximately five-fold higher in African Americans. Many studies have shown that low birth weight is strongly associated with increased risk of hypertension, stroke, and myocardial infarction.(More)
OBJECTIVES This study assessed the prevalence, incidence, and persistence of nontraumatic rotator cuff tendinitis and shoulder symptoms over a 1-year period in a working population and the predictive value of symptoms and physical findings. METHODS A 1-year prospective study of 436 active workers was conducted at 12 different worksites. Detailed health(More)
The purpose of this article was to assess validity of the regional Disabilities of Arm, Shoulder, and Hand (QuickDASH) and Short-Form 12 (SF-12) for surveillance purpose. We compared the predictive, discriminate, and concurrent validity of the QuickDASH and SF-12 among 231 workers with specific clinical diagnoses of neck or upper extremity musculoskeletal(More)
OBJECTIVE We quantified the underreporting of work-related injury or illness to workers' compensation (WC). METHODS Using data from 2612 wage-earning respondents who participated in the 2002 Washington State Behavioral Risk Factor Surveillance System, we assessed work-related injury or illness in the previous year and identified the factors associated(More)
BACKGROUND Few large epidemiologic studies have used rigorous case criteria, individual-level exposure measurements, and appropriate control for confounders to examine associations between workplace psychosocial and biomechanical factors and carpal tunnel syndrome (CTS). METHODS Pooling data from five independent research studies, we assessed associations(More)
OBJECTIVES The aim was to explore whether "adjustment" for gender masks important exposure differences between men and women in a study of rotator cuff syndrome (RCS) and carpal tunnel syndrome (CTS) and work exposures. METHODS This cross-sectional study of 733 subjects in 12 health care and manufacturing workplaces used detailed individual health and(More)
OBJECTIVE To identify factors associated with rotator cuff syndrome (RCS) among active workers. METHODS Seven hundred thirty-three workers in 12 worksites participated in a cross-sectional study with individual structured physical and psychosocial health interviews, physical examinations, and exposure assessments of biomechanical factors.
