Total PA was assessed with Actigraph accelerometers (AG;
Model 7164, version 2.2; ActiGraph Health Services, Fort Walton
Beach, Florida, USA), which were programmed to record PA over
one-minute intervals (60 s epoch). The accelerometers were worn
on the hip for six consecutive days, four week days and two
weekend days, from the time the participant woke up until he or
she went to sleep. Only data from monitors worn a minimum of
8 hours per day, for at least two weekdays and one weekend day
were included in the analysis. Average counts per minute (cpm) for
these days measured by the accelerometer were calculated for
each participant and were used to estimate PA level. Details about
PA measured with ActiGraph accelerometers have been described
previously [13].
