title: Effect of impairment and disability on health-related quality of life of elderly: a community-based study from urban India.
abstract: BACKGROUND
  Increasing population of elderly and the emergence of epidemic of chronic or (non-communicable) diseases, which is likely to adversely affects their health-related quality of life (HRQOL), has implications on health systems in developing countries such as India. A study was conducted to know the common impairments and disabilities and their effect on HRQOL in elderly population.
  
  
  METHODS
  A community-based cross-sectional study on elderly, selected by cluster sampling from central Delhi, India, was conducted from April 2005 to February 2006. A pre-tested, semi-structured questionnaire, along with Short Form -36 (SF-36) survey was used for data collection. The data was analyzed using Chi square and student's t test on SPSS v12 statistical software. P value of less than 0.05 was considered statistically significant.
  
  
  RESULTS
  A total of 200 elderly were included in the study. 71.5% subjects had at least one disability/impairment. Around 40% subjects reported their health being poor and another 50% of worsening of their health in the last 1 year. HRQOL score for people with and without chronic morbidity/disability was 51.8 and 73.5, respectively (P<0.05), with overall mean score 56.7 (±17.2). The most commonly affected HRQOL domains were Role Physical, Physical Functioning, and General Health. The HRQOL and domain scores decreased with increasing age, and females had lower mean scores than males (P<0.05).
  
  
  CONCLUSIONS
  The HRQOL of elderly in urban India is severely affected by impairments and disabilities. There is an immediate need for specific preventive and rehabilitative measures targeted on elderly to maintain their health related quality of life. This information may be utilized for designing any policy and/or program targeted for elderly in India and in other similar settings.
