Abstract Body

Background and purpose China is expected to face an enormous increase of people with dementia. Approximately 40% of all dementia cases might be attributable to potentially modifiable risk factors, suggesting the potential to delay or prevent dementia when targeting these risk factors. In this qualitative study, we aim to explore the experiences, needs and views of older Chinese adults regarding healthy lifestyles for the prevention of dementia, facilitating development of a coach-supported mobile health (mHealth) platform in the Prevention of Dementia using Mobile Phone Applications (PRODEMOS)-study.

Methods Eligibility criteria were an age >55, increased dementia risk without a diagnosis of dementia, and possession of a smartphone. Semi-structured interviews were performed by nine Chinese researchers. Data were analysed through thematic analysis.

Results We performed 26 interviews with participants from Beijing and Tai’an, aged 55-86 years. We identified three main themes: ‘valuing a healthy lifestyle’, ‘sociocultural expectations’, and ‘need for guidance’. First, a healthy lifestyle was deemed important. Participants had tried to change their behaviour using both generic and specific Chinese approaches. Second, an important motive to stay healthy was to limit the burden put on family members. Paradoxically, time-consuming family and other social obligations could also impede healthy behaviours. Finally, participants expressed a need for reliable and personalised lifestyle support from a health professional.

Conclusions In spite of their clear appreciation of healthy lifestyles, Chinese older adults express a need for personalised lifestyle support. The PRODEMOS mHealth platform was adapted to meet these needs. Efficacy and implementation will be tested in a trial that is currently ongoing.
