Factors affecting daily instrumental activities of the elderly

BACKGROUND/AIM: In order to determine elderly people's capabilities in daily activities, we evaluated the factors that may affect their daily instrumental activities. MATERIALS AND METHODS: We performed an observational, analytical, and cross-sectional study on 101 patients above 60 years of age in 2008 and 2009. We applied the Lawton Instrumental Activity of Daily Living (IADL) scale, the Standardized Mini-Mental State Examination (SMMSE), and the Geriatric Depression Scale (GDS) during one-on-one interviews with the patients. Demographic data and disability levels were also recorded. These data were used to evaluate the possible effects of factors on the IADL scale. RESULTS: Statistical analyses indicated that total scores of instrumental activities are affected negatively by increased age, female sex, and literacy (P < 0.001, P = 0.005, and P = 0.021), whereas scores are affected positively by educational level (P = 0.047). CONCLUSION: Our findings suggest that increased age, sex, literacy, and education levels influence elderly people's daily instrumental activities. Daily functional activities and factors influencing these activities should be determined in order to increase elderly people's quality of life and independence. It is important to evaluate elderly people's capabilities in daily activities.
