Racial differences in the incidence of gout

Abstract

Objective. To estimate the incidence of and examine risk factors for the development of gout in black and white male physicians.Methods. Data from 2 cohorts of former medical students, 352 black men in the Meharry Cohort Study and 571 white men in the Johns Hopkins Precursors Study, were analyzed. Cases of gout were identified by self-report. Baseline variables and incident hypertension were examined as risk factors for the development of gout in both cohorts.Results. The incidence of gout was 3.11 and 1.82 per 1,000 person-years in the black men and the white men, respectively (P < 0.05); the cumulative incidence was 10.9% and 5.8%, respectively (P = 0.04). The relative risk (RR) for gout among the black men was Conclusion.The approximately 2-fold excess risk for gout among black men is explained, in part, by a greater risk of incident hypertension.Gout is the most common form of inflammatory arthritis in men aged 40 and older, with a prevalence approaching 5% (1). Data from the United States National Health Interview Survey indicate that the prevalence of gout and the morbidity associated with gout are greater in black men than in white men (2). Several longitudinal studies have estimated the incidence of and examined risk factors for gout (3-10). These studies, however, have been limited to whites in the United States and Europe; no data are available on the incidence of gout among blacks, and the only data on risk factors for gout in blacks are derived from a single case-control study (1 1).In the present study, we estimated the incidence of and examined potentially modifiable risk factors for gout in 2 cohorts of former medical students who matriculated at Meharry Medical College and The Johns Hopkins University School of Medicine and were followed up for 26-34 years. Black men had a 70% greater risk of developing gout than white men. This excess risk appears primarily related to the excess risk of developing incident hypertension in black men. These data suggest that intensive efforts directed toward both hypertension prevention and treatment of hypertension with either nonpharmacologic approaches or pharmacologic agents that don't produce secondary hyperuricemia may be effective in reducing the incidence of and morbidity from gout in black men.

Coffee consumption and risk of incident gout in men: A prospective study

“…Our study was substantially larger than previous studies concerning gout (1,(49)(50)(51)(52)(53)(54), and dietary data including coffee intake information were prospectively collected and validated. Potential biased recall of diet was avoided in this study because the intake data were collected before the diagnosis of gout.…”

Frequency of Gouty Arthritis in Patients with End-stage Renal Disease in Japan

“…The prevalence of gouty arthritis is 10% to 20% in patients with hyperuricemia in the general population (6,7) and shows the racial differences (8). In Western patients with end-stage renal disease (ESRD) and high serum levels of uric acid, the incidence of gouty arthritis is low (9); however the incidence in Japanese patients is unclear.…”

Epidemiologi av urinsyregikt

“…Rase/befolkningsgruppe I en studie av medisinstudenter, 352 svarte menn i Meharry Cohort studien og 571 hvite menn i Johns Hopkins Precursor studien, var relativ risk (RR) for urinsyregikt hos svarte menn 1,69 (95% CI 1,02-2,80) sammenlignet med hvite menn (29). Dette ble forklart med en høyere risiko for hypertensjon blant de svarte.…”
