Health-related quality of life and activities of daily living in 85-year-olds in Sweden.

Few studies have examined health-related quality of life (HRQoL) with respect to daily living and health factors for relatively healthy elderly individuals. To this end, this study examines 85-year-olds' reported HRQoL in relation to social support, perceived health, chronic diseases, healthcare use and instrumental activities of daily living (IADL). Data were collected from 360 participants (55% response rate) between March 2007 and March 2008 using a postal questionnaire and a home visit interview. HRQoL was assessed using the EQ-5D-3L. For the items in the EQ-5D-3L, more problems were related to lower HRQoL. Restricted mobility and occurrence of pain/discomfort was common. Lower HRQoL was associated with increased risk for depression, increased use of medication, increased number of chronic diseases and more problems with IADL. Healthcare use and healthcare costs were correlated with lower HRQoL. HRQoL is of importance to healthcare providers and must be considered together with IADL in the elderly population when planning interventions. These should take into account the specific needs and resources of the older individuals.
