Correlates of geriatric depression scale with perceived quality of life in an elderly population

Background: Depression, a very incapacitating disease, is associated with enhanced risk of co-morbidities as well as impairment of quality of life among elderly.  
Objective: The aim of this study was to address possible associations between health-related quality of life variables and risk of depression among elderly.
Patients  and  Methods:  In  a  case-control  study  we  compared  28  depressive  subjects  with 118-matched  controls  attended  at  a  public  social  assistance  unit. The  odds  ratio  (OR)  of depression as well as the OR for each quality of life factors were estimated.
Results: Lower perceived quality of life, increased prevalence of negative feelings, presence of  at  least  two  co-morbidities,  life  dissatisfaction,  poor  perceived  mobility,  and  excessive
medication  use  (4  or  more  drugs)  were  significantly  associated  with  increased  OR  for depression. Although poor sleep had been inclined to be associated with risk of depression this trend was not statistically significant (P < 0.058).
Conclusions: Whereas the lower health-related quality of life factors negatively impact the risk of disease, health satisfaction had a positive and inverse effect on depression’s risk of the elderly.

Core tip: Among a group Brazilian sample of elderly people, lower perceived quality of life, excessive medication use, and presence of two or more co-morbidities were the major factors associated with increased risk of depression, whereas satisfaction with health decreased the odds for that disorder.
