The objective of this study was to determine the prevalence of symptoms and the morbidity associated with Raynaud's phenomenon (RP) among African Americans.
A total of 2196 randomly selected residents of an inner-city community, in Baltimore, completed a health-assessment survey.
Symptoms of RP consisted of cold sensitivity plus cold-induced white or blue digital color change.
One third (n=703) reported cold sensitivity and 14% (n=308) reported digital color change ; 84 residents with symptoms of RP were identified, yielding an overall prevalence rate of 3.8% (95% confidence interval [CI] 3.0-4.6).
RP was associated with poor or fair health status (odds ratio [OR]=1.82, Cl 1.18-2.81), heart disease (OR=2.32, Cl 1.39-3.87), and stroke (OR=2.20, Cl 1.17-4.15), after adjustment for age, gender, and physician-diagnosed arthritis.
The prevalence of symptoms of RP in this African-American community is comparable to published reports from other populations.
These community-based data suggest that identification of RP among African Americans should raise consideration of possible comorbidity, particularly cardiovascular disease.
