The purpose of this analysis was to investigate the prevalence and correlates of Restless Legs Syndrome (RLS) symptoms in the 2005 National Sleep Foundation (NSF) Sleep in America 2005 Poll.
The NSF poll is an annual telephone interview of a random sample of United States adults 18 years of age and older who are representative of the US population. Respondents are queried about many aspects of sleep, sleep disorders and daily living.
The NSF 2005 poll included 1506 adults. Their mean age was 49 years, and 775 were women. Symptoms of RLS that included unpleasant feelings in the legs for at least a few nights a week and which were worse at night were reported by 9.7 % of individuals in this poll, including 8% of men and 11% of women. Those from the South and West were more likely to be at risk for RLS than those from the Northeast (p< 0.05). Those who were unemployed or smoked daily were more likely to be at risk for RLS, as were those with hypertension, arthritis, gastroesophageal reflux disease, depression, anxiety, and diabetes. Adults who were at risk for RLS appeared to also be at increased risk for sleep apnea and insomnia, and were more likely to stay up longer than they planned, to take longer than 30 minutes to fall asleep, to drive when drowsy, and to report daytime fatigue than those who were not at risk. They were also more likely to report being late to work, missing work, making errors at work, and missing social events because of sleepiness than other respondents in the poll.
RLS is significantly associated with medical and psychiatric conditions, with other sleep disorders, with unfavorable lifestyle behaviors, and with adverse effects on daytime function.
Chest physicians who practice Sleep Medicine need to be able to manage RLS, which is prevalent and is associated with considerable morbidity.
