Disability for basic and instrumental activities of daily living in older individuals

To know the prevalence, associated factors and temporal trends of disabilities for basic and instrumental activities of daily living in older people in Spain from 2009 to 2017.

Disability in older people is associated with health problems, increased health costs and low quality of life. There are no updated data in Spain with a representative sample about disability.

Cross-sectional study with 25,465 non-institutionalized older people who participated in the European Health Survey in 2009 and 2014 and the National Health Survey in 2011/12 and 2017 in Spain. The prevalence rates of disability were evaluated using the Katz Scale and Lawton and Brody Scale. Logistic regression was used to determine if there was an association between basic and instrumental activities of daily living and sociodemographic characteristics.

More individuals had disability for instrumental activities of daily living (31.9%) than disability for basic activities of daily living (11.1%). The most predominant disability for instrumental activities of daily living was performing severe housework (34%). The prevalence of disabilities decreased from 2009 to 2017. In general, disability was associated with female gender, advanced age, lower education, restricted daily activity, being bedridden and higher pain levels.

There is a considerable prevalence of disabilities for basic and instrumental activities of daily living in older people in Spain. Although the disability prevalence has decreased slowly from 2009 to 2017, it continues to remain a health problem. Gender may influence the disabilities for basic and instrumental activities of daily living. Health policymakers should establish prevention strategies and effective interventions (e.g., physical exercise) for prevention and reduction of the disabilities for basic and instrumental activities of daily living, particularly in older females.
