OBJECTIVE To estimate the point prevalence of fibromyalgia syndrome (FM) among noninstitutionalized Canadian adults; and to assess the effect of demographic variables on the odds of having FM. METHODS A screening questionnaire was administered via telephone to a random community sample of 3395 noninstitutionalized adults residing in London, Ontario.(More)
Residual renal function (RRF) in end-stage renal disease is clinically important as it contributes to adequacy of dialysis, quality of life, and mortality. This study was conducted to determine the predictors of RRF loss in a national random sample of patients initiating hemodialysis and peritoneal dialysis. The study controlled for baseline variables and(More)
BACKGROUND Dementia shortens life expectancy; estimates of median survival after the onset of dementia have ranged from 5 to 9.3 years. Previous studies of people with existing dementia, however, may have underestimated the deleterious effects of dementia on survival by failing to consider persons with rapidly progressive illness who died before they could(More)
OBJECTIVE To compare function and disability in fibromyalgia syndrome (FMS) cases in the community versus controls, and to identify variables predicting poor function and disability. METHODS We identified 100 FMS cases, 76 pain controls, and 135 general controls in a random survey of 3,395 noninstitutionalized adults. RESULTS FMS cases reported worse(More)
BACKGROUND There are several widely used sets of criteria for the diagnosis of dementia, but little is known about their degree of agreement and their effects on estimates of the prevalence of dementia. METHODS We examined 1879 men and women 65 years of age or older who were enrolled in the Canadian Study of Health and Aging and calculated the proportion(More)
OBJECTIVE To develop and test an instrument to screen for fibromyalgia syndrome (FM) in general population surveys. METHODS We designed a questionnaire with 4 pain and 2 fatigue items. A positive screen was defined 2 ways: (1) positive responses to all 4 items on pain, and (2) positive responses to all pain and fatigue items. Sensitivity was tested in the(More)
BACKGROUND Obese individuals have increased morbidity and use of health services. Less is known about the effect of obesity on workers' compensation. The objective of this study was to determine the relationship between body mass index (BMI) (calculated as weight in kilograms divided by height in meters squared) and number and types of workers' compensation(More)
OBJECTIVES To estimate the prevalence of lower urinary tract symptoms (LUTS) by severity (using the International Prostate Symptom Score, IPSS) in a population-based study of men aged > or = 20 years, and to assess the association between putative risk factors and the presence of moderate to severe LUTS. SUBJECTS AND METHODS Between 1995 and 1997, LUTS(More)
OBJECTIVE To identify demographic and clinical features that distinguish fibromyalgia (FM) from other chronic widespread pain. METHODS We identified 100 confirmed FM cases, 76 widespread pain controls, and 135 general controls in a random community survey of 3395 noninstitutionalized adults living in London, Ontario. FM cases were distinguished from pain(More)
BACKGROUND AND OBJECTIVE The ideal suture for abdominal fascial closure has yet to be determined. Surgical practice continues to rely largely on tradition rather than high-quality level I evidence. The authors conducted a systematic review and meta-analysis of randomized controlled trials to determine which suture material and technique reduces the odds of(More)
