What drives the use of wearable healthcare devices? A cross-country comparison between the US and Korea

Abstract

Objective Given the rapid growth of the wearable healthcare device market, we examined the associations among health-related and technology-related characteristics of using wearable healthcare devices and demonstrated how the associations differ between the US and Korean users. Methods Online self-administered surveys were conducted with 4098 participants (3035 in the US and 1063 in Korea) who were recruited through two online survey service providers based on quota sampling. The primary outcome was the use of wearable healthcare devices. Seven health-related, two technology-related, and five socio-demographic factors were included as explanatory variables. Binary logistic regression analyses and a Chow test were conducted. Results The health-related characteristics that were significantly associated with using wearable healthcare devices included disease-related worries (beta = 0.11**), health information seeking (beta = 0.26***), physical activity (beta = 0.62***), and health-related expenditures ($50-$199, beta = 0.38***; $200 or more, beta = 0.56***). Hedonic (beta = 0.33***), social (beta = 0.31***), and cognitive innovativeness (beta = 0.14*) also exhibited positive relationships. Younger, higher earner, and individuals with a child were more likely to use wearable healthcare devices. However, for Korean users, several associations disappeared including health information seeking, hedonic and social innovativeness, age, and household income. Conclusions Key drivers of using wearable healthcare devices include greater concern about a specific illness, active engagement in health-promoting behaviors, and hedonic and social motivation to adopt new technologies. However, more country-specific considerations are needed in future studies to identify the main benefits for target markets.
