In a door-to-door survey conducted in two municipalities of Sicily, we ascertained the prevalence of diabetic neuropathy. Our case-finding was restricted to subjects with somatic symptoms. During phase 1, we administered a screening instrument for peripheral neuropathy to 14,540 persons residing in Santa Teresa di Riva (Messina Province) and Terrasini (Palermo Province). During phase 2, neurologists evaluated those subjects who had screened positive. Diagnoses were based on clinical criteria only, and were reviewed by an adjudication panel. We found 39 persons (27 women, 12 men) affected by diabetic neuropathy. The crude prevalence, as of November 1, 1987, was 268.2 cases per 100,000 population. The prevalence increased with advancing age for both sexes and was consistently higher in women. The most common type was distal symmetric polyneuropathy. The median time between diagnosis of diabetes mellitus and onset of diabetic neuropathy was 8 years, and almost all identified persons with diabetic neuropathy were under treatment for diabetes mellitus.
