Figure 2. Prevalence of restless legs syndrome by acculturation, age, and gender.

The high acculturation HMD group had significantly higher prevalence of RLS when compared to the low acculturation group (17.4% vs. 12.8%, p = 0.008). The low acculturation younger men* had significantly lower prevalence of restless legs syndrome (7.4% vs. 15.4%) than the high acculturation younger men (Pearson χ², 2-sided, p = 0.003). There was also a large difference in the RLS prevalence of the low and high acculturation older men, but this was not statistically significant (p = 0.147).
