BACKGROUND
China is expected to face among the largest increase of people with dementia worldwide in the coming decades, seriously challenging the Chinese healthcare system. 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. Mobile health (mHealth) may improve the accessibility of such dementia prevention strategies in China, given the wide and increasing use of smartphones by the entire Chinese population, including older adults.
OBJECTIVE
The aim of this qualitative study is to explore the needs and views of Chinese older adults regarding healthy lifestyles to prevent cardiovascular disease (CVD) and dementia through mHealth, facilitating development and cultural adaptation of a coach-supported mHealth platform for the Prevention of Dementia using Mobile Phone Applications (PRODEMOS) study.
METHODS
We performed semi-structured interviews with older adults, aged 55 and over, from Beijing and Tai’an, China, with an increased dementia risk without a diagnosis of dementia, who possess a smartphone. Participants were recruited through seven hospitals that participate in the PRODEMOS study, and were purposively sampled on age, sex, living situation, and history of CVD and diabetes. Data were analysed using thematic analysis.
RESULTS
Between February and December 2019 we performed 26 interviews with participants aged 55-86 years. Three main themes were identified: valuing a healthy lifestyle, sociocultural expectations, and need for guidance. First, following a healthy lifestyle was generally deemed important. In addition to generic healthy behaviours, participants regarded certain specific Chinese behaviours as important to prevent disease. Second, the sociocultural context played a crucial role, as an important motive to avoid disease was to limit the burden put on family members. However, time-consuming family and other social obligations could also impede healthy behaviours, such as regular physical activity and a healthy diet. Finally, there seemed to be a need for reliable and personalised lifestyle advice and for guidance from a health professional.
CONCLUSIONS
In spite of their clear appreciation of healthy lifestyles, Chinese older adults express a need for personalised lifestyle support in order to adopt healthy behaviours. Potentially, the PRODEMOS mHealth intervention can meet these needs through blended lifestyle support to improve risk factors for CVD and dementia.
