P09-09 Hybrid work and temporal patterns of sedentary behavior in a 24-hour compositional perspective

Abstract Background During the COVID-19 pandemic, many white-collar workers were requested to exclusively work from home (WFH), which may have affected their sedentary behavior. In Sweden, having less severe restrictions than other countries, allowed alternate between WFH and at office (WAO), so called hybrid work. Understanding how influences total behavior its temporal distribution is an important issue for future health promotion. This study aimed investigate what extent changed pattern of during days compared WAO, considering age gender as potential moderators. Methods Data collected May December 2020 in (n = 199). Their mean was 42 (SD 10) years 55% women. Physical behaviors measured using a thigh-worn accelerometer (AxivityAX3) seven consecutive days. A diary identified working hours, time-in-bed or WAO. Time-use classified short (0-5 min), moderate (5-30 min) long bouts (>30 (SB), non-SB, workdays (WAO WFH) non-workdays. We used Compositional data analysis express 24-hour compositions linear mixed models estimate difference day types (within worker), including covariates Results found that (WFH WAO) associated with proportionally relative time awake, more SB longer shorter bouts, non-workdays (all p > 0.001). awake non-SB WAO (p 0.05), but differences not significant. Younger women had SB, accumulated men SB. However, did affect types. Conclusions Working influenced time-use by increasing total, while unchanged. contribute evidence can support organizational policies on
