Associations between information and communication technology use and frailty in community-dwelling old-old adults: results from the ILSA-J

Abstract

Abstract Objectives Frailty is a significant cause of adverse health events including long-term care and hospitalization. Although information and communication technology (ICT) has become an integral part of modern life, it remains unclear whether ICT use is associated with frailty. Design A cross-sectional study (Integrated Longitudinal Studies on Aging in Japan, ILSA-J). Setting and participants Aged 75 and older data from the ILSA-J in 2017 (n = 2893). Methods ICT use was measured using the technology usage sub-items of the Japan Science and Technology Agency Index of Competence. Specifically, the use of mobile phones, ATMs, DVD players, and sending e-mails were rated as “yes” (able to do) or “no” (unable to do), with the first quintile (≤1 point) defined as ICT non-users. Frailty was assessed using the Japanese version of the Cardiovascular Health Study criteria based on the phenotype model (e.g., weight loss, slowness, weakness, exhaustion, and low activity). Further, multivariate logistic regression analysis analyzed its association with ICT use. Subgroup analyses were stratified according to gender, years of education, and living arrangements. Results Higher ICT use was not associated with frailty after adjusting for covariates (odds ratio [OR]: 0.53; 95%CI 0.39–0.73). Similar associations were found in the sub-groups of women (OR 0.45, 95%CI 0.30–0.66), <13 years of education (OR 0.48, 95%CI 0.34–0.67), living alone (OR 0.46, 95%CI 0.27–0.79), and living together (OR 0.57, 95%CI 0.38–0.85). No association existed between using ICT and frailty in the sub-groups of men and ≥13 years of education. Conclusions and implications Higher ICT use is associated with the absence of frailty in individuals 75 years and older. Such benefits may be particularly pronounced in women, those with lower levels of education, and older adults living alone or with others.
