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