A survey conducted through personal interviews was done in Canada to estimate the prevalence of subjective symptoms related to restless legs syndrome (RLS) and to sleep bruxism. Of the 2,019 respondents, all over 18 years of age, 15% reported leg restlessness at bedtime; 10% reported unpleasant leg muscle sensations associated with awakening during sleep and with the irresistible need to move or walk. Both these complaints are related to RLS. The prevalence of RLS-related symptoms increased linearly with age. Tooth grinding, a symptom related to sleep bruxism, was reported by 8% of the subjects; in contrast to RLS-related symptoms, the prevalence of tooth grinding decreased linearly with age. RLS-related symptoms were reported more frequently in Eastern provinces than in Ontario and Western Canada, and more frequently in Roman Catholic and French-speaking responders. This was not the case for sleep bruxism; between 14.5% and 17.3% of the subjects who reported subjective RLS-related symptoms also reported tooth grinding. Conversely, 9.6-10.9% of the tooth grinders reported RLS-related symptoms. These data suggest that both sleep movement disorders can be concomitant and that socio-geographic and age characteristics influence the prevalence of reports.
在加拿大开展了一项通过个人访谈进行的调查，以估计与不宁腿综合征（RLS）及睡眠磨牙症相关的主观症状的患病率。在2019名年龄均在18岁以上的受访者中，15%报告称睡前腿部不安；10%报告称睡眠中醒来时腿部肌肉有不适感，且有难以抑制的活动或行走需求。这两种主诉均与RLS有关。与RLS相关症状的患病率随年龄呈线性增加。8%的受试者报告有磨牙症状，这是与睡眠磨牙症相关的症状；与RLS相关症状不同，磨牙症状的患病率随年龄呈线性下降。与RLS相关的症状在东部省份的报告频率高于安大略省和加拿大西部，在罗马天主教徒和说法语的受访者中报告频率更高。睡眠磨牙症的情况并非如此；在报告有与RLS相关主观症状的受试者中，14.5%至17.3%的人也报告有磨牙症状。相反，9.6%至10.9%的磨牙者报告有与RLS相关的症状。这些数据表明，这两种睡眠运动障碍可能同时存在，且社会地理和年龄特征会影响报告的患病率。
