Prevalence of Raynaud phenomenon in the general population. A preliminary study by questionnaire.
A short questionnaire inquiring about cold sensitivity of the fingers was administered to 1752 randomly selected subjects in a probability sample drawn from the adult population of the state of South Carolina. The overall prevalence of reported cold sensitivity was approximately 10% and showed no sex or race difference. A female preponderance was revealed only after subjects exposed to vibrating tools were excluded, and then only in the white group. Estimates of the prevalence of Raynaud phenomenon were obtained using the following criteria: cold sensitive subjects reporting white and/or blue color changes: 4.6%; cold sensitivity leading to medical consultation: 3.0%; combination of the two criteria above: 1.9%.
