We present findings from three waves of a population-representative, UK time-use diary survey conducted both pre- and in real time during full 'lockdown', and again following the easing of social restrictions. We used an innovative online diary instrument that has proved both reliable and quick-to-field. Combining diary information on activity, location, and co-presence to estimate infection risks associated with daily behavior, we show clear changes in risk-associated behavior between the pre, full-lockdown and post full-lockdown periods. We document a shift from more to less risky daily behavior patterns (combinations of activity/location/co-presence categories) between the pre-pandemic pattern and full lockdown in May/June 2020, followed by a reversion (although not a complete reversal) of those patterns in August 2020 following the end of the first lockdown. Because, in general, a populations' time use changes relatively slowly, the behavioral changes revealed may be interpreted as a consequence of the UK COVID-19 lockdown social restrictions and their subsequent relaxation.
我们展示了在英国全范围封锁期间以及封锁解除后进行的三次具有代表性的、基于人群的、使用时间记录日记的调查结果。我们使用了一种创新的在线日记工具，这种工具既可靠又便于快速开展调查。通过结合活动、地点和共同在场的日记信息来估计与日常行为相关的感染风险，我们发现了在封锁前、全封锁和全封锁解除后期间与风险相关的行为的明显变化。我们记录了从大流行前模式到 2020 年 5 月/6 月全封锁期间风险相关行为模式（活动/地点/共同在场类别的组合）的转变，随后在 2020 年 8 月第一次封锁结束后，这些模式出现了逆转（尽管不是完全逆转）。由于一般来说，人群的时间使用相对较慢变化，因此揭示的行为变化可以被解释为英国 COVID-19 封锁社会限制及其随后放松的结果。
