The status of step-count monitoring and its association with physical activity and sedentary time among older adults: a cross-sectional study of silver human resources center members.

[Purpose] This study aimed (1) to describe the actual status of step-count monitoring among older adults who are members of Silver Human Resources Centers, one of the major organizations supporting older adults' work in Japan, and (2) to examine its relationships with physical activity and sedentary time (ST). [Participants and Methods] A total of 622 participants were included in this study. Logistic regression models were used to evaluate associations between step-count monitoring frequency and exercise habits, while multiple linear regression models examined associations with ST. [Results] Of the participants, 33.6% reported monitoring their steps almost every day. "Mobile phone/smartphone" was the most used device for step-count monitoring. A higher frequency of step-count monitoring was positively associated with exercise habits, with the multivariable-adjusted odds ratio (95% CI) of 3.329 (2.266-4.891) for the high-frequency monitoring group compared to the non-monitoring group. No significant association was observed between step-count monitoring frequency and ST. [Conclusion] This study highlights the widespread practice of step-count monitoring among older adults and its positive association with exercise habits. These findings provide foundational insights for developing dissemination strategies to promote step-count monitoring in this population.
