To measure the level of sleep disorders among patients with chronic obstructive pulmonary disease, and to see if there was any difference in terms of demographic variables and socioeconomic status. The cross-sectional descriptive observational study was conducted from March to June 2017, and data was collected through purposive sampling from different tertiary health care centres of Faisalabad, Pakistan. Sleep-50-Urdu scale was used to measure sleep disorders among patients with chronic obstructive pulmonary disease. SPSS 21 was used for data analysis. Of the 140 respondents 70(50%) each were males and females with an overall mean age of 48.64±17.39 years. The patients had significantly high level of narcolepsy (p<0.05), but those from high socioeconomic status had relatively lower level of narcolepsy (p<0.05). Male patients and people from lower socioeconomic status also suffered from sleep apnoea and insomnia along with chronic obstructive pulmonary disease (p<0.05). Narcolepsy along with sleep apnoea and insomnia were significantly more prevalent among chronic obstructive pulmonary disease patients from lower socioeconomic status.
