PURPOSE:  Establish the prevalence of restless leg syndrome (RLS) in African American (AA) and non African American (NAA) in primary care clinic.

METHODS:  We examined the prevalence of RLS using one-on-one interviews in primary care clinic. Subjects were selected during visits with primary physicians over a course of 3 months. Subjects were interviewed using John Hopkins Telephone Diagnostic Interview (HDTI). All interviews were conducted by trained interviewers.

RESULTS:  A total of 190 patients were interviewed. 103 AA and 87 NAA. The cumulative prevalence of definite RLS was 23%. In the AA group, 42% were male and 58% were female. In the NAA group, 40% were male and 60% were female. The average age of AA was 53 (SD 15) and the average age of NAA was 50 (SD 13).Among AA, the diagnosis of RLS was definite in 12%, 4% were probable RLS, 83% were negative and 1% was diagnosed as uncertain. Among NAA, the diagnosis of RLS was definite in 36%, 64% negative. There were no patients diagnosed as probable RLS or uncertain.In the AA group, the prevalence of RLS was 12% in both gender groups. In the NAA group, the prevalence of RLS among males was 29% and 40% among females.

CONCLUSION:  RLS is common among in our primary care clinic in both AA and NAA. Overall prevalence was 23%. NAA prevalence is 3 times higher than AA in our patient population. Among males, RLS is 2 times more prevalent in NAA than AA. Among females, RLS seems to be 4 times more prevalent in NAA than AA.

CLINICAL IMPLICATIONS:  Our study suggests that RLS is less prevalent among AA compared to NAA in our region. Nonetheless, the cumulative prevalence in this study of 23% is much higher than previous studies, which generally was 3% to 10%. In general, RLS seems to be more prevalent than previously suggested among the AA. RLS appears to be most common among NAA females.
