Socio-demographic risk factors of mobility dysfunction and limitations in physical functioning disability among the elderly in Iran: A nationwide cross sectional survey.

OBJECTIVE

To examine self-reported mobility and limitation in physical functioning among the elderly and associated socio-demographic risk factors.

METHODS

The population-based cross-sectional study was conducted from January 2012 to January 2013 and comprised subjects from five provinces of Iran. The variables were measured using a questionnaire. Self-reported mobility disability and physical functioning disability were defined as having no problems in daily activities and physical tasks. Logistic regression was used to calculate the odds ratio for association of socio-demographic risk factors and outcomes.

RESULTS

Of the 1325 subjects, 636(48%) were men. The overall mean age was 69.14±7.37 years. Prevalence of mobility disability and limitation in physical functioning was 401(63%) and 553(87%) in men, and 524(76%) and 641(93%) in women. There was a significant association between mobility disability and family composition and satisfaction with financial situation and housing tenure in both genders (p<0.05 each). Physical functioning had a significant relationship with family composition, and satisfaction with financial situations and housing tenure in men and women and population density in men and marital status in women (p<0.05 each).

CONCLUSIONS

The elderly had a high risk of disability. Social factors had more association with mobility disability and limitation in physical functioning and required specific social support.
