Living Arrangement of Older Adults and its Effect on Five-Year Survival

Given the impact of living alone on health outcomes, this study was conducted to assess the living arrangement of senior adults and its effect on the mortality.

This cohort study carried out on elderly people aged 60 years and over. Demographic characteristics, the number of comorbid disorders and living condition-as being alone or living with other people-were collected. The mini-mental state examination questionnaire, the geriatric depression scale, the Katz index of activities of daily living, the Lawton instrumental activities of daily living scale, and a modified version of Duke social support index were used for data collection. The participants were followed for five years, and their survival was assessed.

Out of the 500 examined individuals, 100 (20.0%) were living alone. During 5 years of follow-up, sixteen (19.8%) of the people who died were living alone. The adjusted effect of age (P<0.001), male gender (P=0.004), the number of comorbidities (P=0.031), the person's social support (P=0.028) and dependence to others to do complex daily activities (P=0.020) on the mortality of the participants was significant, however, other factors including living alone, illiteracy, cognitive impairment and depression did not show such a statistically significant effect (P>0.05).

Living arrangement, itself, did not show a significant effect on the mortality of older adults.
