Although individual risk and time preferences appear to be associated with (un)healthy behaviors, limited evidence exists regarding whether domain-specific physical activity and sedentary behaviors vary according to risk and time preferences. This study investigated the association of risk and time preference with domain-specific physical activity and total sedentary time among Japanese working adults. This study recruited 2400 Japanese workers via an internet survey conducted in March 2022 and assessed their risk preferences, time preferences, domain-specific physical activity times, total sedentary time, and sociodemographic characteristics. Data were analyzed using a multiple regression analysis. Multiple regression analysis indicated that a risk-averse disposition in risk preference was significantly associated with lower total sedentary time. No statistically significant relationship was observed between risk preference and any physical activity measure. A higher time preference was significantly associated with higher moderate-to-vigorous physical activity during work and with lower total sedentary time. Individual risk preferences were not clearly related to domain-specific physical activity. In contrast, higher time preference was modestly associated with physical activity in work-related contexts. Given that both risk and time preferences were linked to total sedentary time, further research is needed to examine sedentary behavior across domains.
