Populations around the world are rapidly ageing. In almost every country, the proportion of people aged over 65 years is growing faster than any other age group. Living longer brings many opportunities, however, it also poses challenges for health care and communication. As older adults often deal with multiple diseases at the same time, the importance of adequate health information seems to increase with age. Besides, there is no ‘typical’ older person. Individual differences increase when people get older. Hence, it is important to consider the wide range of older adults’ experiences and needs. ACHC research in this area focuses on how offline and online communication can be used to optimize information provision to older adults.
