Sleep quality index among the elderly population in selected areas of Delhi: a community-based cross-sectional study

Background Studies have shown that effects of low sleep quality can include cognitive decline, sleepiness during the day, and decreased quality of life. Problems with sleep have also been associated with an increased risk of hospitalization and increased mortality. Therefore, the present study was envisaged to assess the sleep quality index and the factors associated with it among the elderly.

Methods This cross-sectional study was conducted in rural and urban setting of Delhi. We selected 115 participants in each area using systematic random sampling. We used a semi structured questionnaire and validated sleep quality index to collect the data.

Results In the present study, only 41 (17.8%) out of 230 individuals were having normal sleep quality and 189 out of 230 individuals were having poor sleep quality. 105 (55.5%) in the rural area (Fatehpur Beri), and 84 (44.5%) in the urban area (Aliganj) were having poor sleep quality respectively. In the rural area, taking sleeping pills and depression were significantly associated with higher scores of sleep quality index.

Conclusions Poor sleep quality was found in 82.2% of elderly participants which was associated with a rural locality, depression, and not taking sleep pills. There is a need to start a sleep hygiene program for the elderly population, particularly in rural area.
