The prevalence of restless legs syndrome and its relationship with demographic characteristics and medical disorders in postmenopausal Iranian women

ABSTRACT

This study was conducted to evaluate the prevalence of restless legs syndrome (RLS) and its relationship with demographic factors and medical disorders on 980 postmenopausal women. Data was gathered using a demographic questionnaire and the International Restless Legs Syndrome Scale. The prevalence of RLS was 16.02% (157/980). Women with poor economic status were 3.37 and 2.33 times more likely to have RLS than women with a good economic situation and moderate economic status (CI:2.041-5.579, P ≤ 0.0001) and (CI: 1.540-3.551, P ≤ 0.0001) respectively. The risk of RLS was 64% greater in women who smoked than in non-smokers. Women with history of hypertension, diabetes and anemia were 2.82, 2.09 and 2.19 times, respectively, more likely to have RLS than those without (P < 0.001). Also women with higher body mass index were more likely to have RLS and women taking hormone replacement therapy were less likely to have RLS. The prevalence of RLS among postmenopausal Iranian women is quite high and there is a relationship between RLS and factors such as age at menopause, education level, a history of smoking, hypertension, anemia and diabetes.
