BACKGROUND Rotator cuff tendinopathy is a common entity. We hypothesized that obesity, because of biomechanical and systemic risk factors, increases the risks of rotator cuff tendinitis, tears, and related surgical procedures. METHODS A frequency-matched case-control study was conducted. Three hundred and eleven patients who were fifty-three to(More)
PURPOSE This study describes the influence of attention deficit hyperactivity disorder (ADHD) on the incidence rates of selected injuries. METHODS A retrospective cohort study design was employed using medical claims data from the Deseret Mutual Benefit Administrators (DMBA), a health insurance company for employees of the Church of Jesus Christ of(More)
A population-based insurance claims database was used to examine cellulitis incidence, anatomical sites of infection, complicating diagnoses, source of health service, and recurrence rates. Insurance claim files were searched for cellulitis ICD-9-CM codes 681.0-682.9. Complications of cellulitis including erysipelas, lymphadenitis, lymphangitis, and(More)
BACKGROUND The epidemiology of fibromyalgia is poorly defined. The incidence of fibromyalgia has not been determined using a large population base. Previous studies based on prevalence data demonstrated that females are 7 times more likely to have fibromyalgia than males and that the peak age for females is during the childbearing years. OBJECTIVE We have(More)
BACKGROUND Osteoarthritis is both the most common form of arthritis and the most common reason for joint replacement surgery. Obese persons are believed to be more likely to develop generalized osteoarthritis that leads not only to knee but also to hip joint replacement surgeries. We hypothesized that obesity is also a risk for partial joint replacements(More)
The Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial has a total enrollment goal of almost 150,000 participants. These participants are being recruited at ten screening centers across the United States. All screening centers tested recruitment methodologies during a 1-year pilot phase. The main phase of recruitment was planned to take(More)
BACKGROUND Estimation of attributable fractions for tobacco and alcohol, and investigation of the association between body mass index (BMI) and head and neck cancer risk have largely been in case-control studies. These aspects and physical activity need to be assessed as possible head and neck cancer risk/protective factors in a cohort study. METHODS In(More)
OBJECTIVE Identify predictors of non-compliance with first round screening exams in the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial. METHOD The PLCO was conducted from 1993 to 2011 at 10 US institutions. A total of 154,897 healthy men and women ages 55-74 years were randomized. Intervention arm participants were invited to receive(More)
BACKGROUND The association between coffee intake, tea intake and cancer has been extensively studied, but associations are not established for many cancers. Previous studies are not consistent on whether caffeine may be the source of possible associations between coffee and cancer risk. METHODS In the Prostate, Lung, Colorectal, and Ovarian cancer(More)
