      abstract     = {The COVID-19 lockdown could engender disruption to
                      lifestyle behaviors, thus impairing mental wellbeing in the
                      general population. This study investigated whether
                      sociodemographic variables, changes in physical activity,
                      and sleep quality from pre- to during lockdown were
                      predictors of change in mental wellbeing in quarantined
                      older adults.A 12-week international online survey was
                      launched in 14 languages on 6 April 2020. Forty-one research
                      institutions from Europe, Western-Asia, North-Africa, and
                      the Americas, promoted the survey. The survey was presented
                      in a differential format with questions related to responses
                      'pre' and 'during' the lockdown period. Participants
                      responded to the Short Warwick-Edinburgh Mental Wellbeing
                      Scale, the Pittsburgh Sleep Quality Index (PSQI)
                      questionnaire, and the short form of the International
                      Physical Activity Questionnaire.Replies from older adults
                      (aged >55 years, n = 517), mainly from Europe $(50.1\%),$
                      Western-Asia $(6.8\%),$ America $(30\%),$ and North-Africa
                      $(9.3\%)$ were analyzed. The COVID-19 lockdown led to
                      significantly decreased mental wellbeing, sleep quality, and
                      total physical activity energy expenditure levels (all p <
                      0.001). Regression analysis showed that the change in total
                      PSQI score and total physical activity energy expenditure
                      (F(2, 514) = 66.41 p < 0.001) were significant predictors of
                      the decrease in mental wellbeing from pre- to during
                      lockdown (p < 0.001, R2: 0.20).COVID-19 lockdown
                      deleteriously affected physical activity and sleep patterns.
                      Furthermore, change in the total PSQI score and total
                      physical activity energy expenditure were significant
                      predictors for the decrease in mental wellbeing.},
