The prevalence of restless legs syndrome (RLS) in India is unknown.
The primary objective was to assess the occurrence of RLS in residents of Bangalore. The secondary objective was to correlate demographic and socioeconomic factors with RLS occurrence and severity.
This was a cross-sectional, questionnaire-based survey conducted during August 2005 among adult residents of Bangalore, who participated in a face-to-face interview. Diagnosis of RLS was based on fulfillment of all National Institutes of Health/International Restless Legs Syndrome Study Group (NIH/IRLSSG) essential criteria. Severity of RLS was assessed using the IRLSSG scale.
RLS occurred in 27 (2.1%) of 1266 respondents. Predominant symptoms included "pulling," "tingling" and "pain". RLS was associated with delayed sleep onset and RLS severity correlated with the duration of delay in sleep onset. RLS was associated with per-capita income less than the equivalent of US$1/day, education less than high school level, chronic daily alcohol consumption and chronic blood loss.
This is the first Indian population study on RLS which reveals prevalence of the disorder in a South Indian urban population at 2.1%. Larger studies are warranted to better characterize RLS in India.
不安腿综合征（RLS）在印度的患病率尚不清楚。
主要目的是评估班加罗尔居民中RLS的发生率。次要目的是将人口统计学和社会经济因素与RLS的发生及严重程度相关联。
这是一项于2005年8月对班加罗尔成年居民进行的基于问卷调查的横断面研究，这些居民参与了面对面访谈。RLS的诊断基于满足美国国立卫生研究院/国际不安腿综合征研究组（NIH/IRLSSG）所有基本标准。使用IRLSSG量表评估RLS的严重程度。
1266名受访者中有27人（2.1%）发生RLS。主要症状包括“牵拉感”“刺痛感”和“疼痛”。RLS与入睡延迟有关，且RLS严重程度与入睡延迟的持续时间相关。RLS与人均收入低于相当于每天1美元、教育程度低于高中水平、每日长期饮酒和慢性失血有关。
这是印度第一项关于RLS的人群研究，揭示了该疾病在南印度城市人口中的患病率为2.1%。需要开展更大规模的研究以更好地描述印度的RLS情况。
