Each annual assessment involves 2 laboratory visits and 7 consecutive days of physical activity monitoring with protocols developed in our pilot work.
We conducted a number of smaller pilot studies [ 18- 21] to develop the protocol, which consists of 2 laboratory visits and 7 consecutive days of physical activity monitoring.
Participants aged 9-16 years used the validated Multimedia Activity Recall for Children and Adolescents (MARCA) [ 17] to provide two consecutive days of physical activity and 'use of time' recall data at both the CAPI and CATI.
Current guidelines from the American Diabetes Association recognise the therapeutic strength of exercise intervention [ 10] and prescribe an exercise frequency of at least three times per week with no more than two consecutive days without physical activity.
Participants were placed on suspended status when they encountered a hospitalization, injury, or other health event that required them to miss more than 2 consecutive weeks of physical activity.
All participants were instructed to wear an accelerometer for up to 7 consecutive days to measure physical activity.Of the 106 dyads enrolled in the study, 80 children and 85 parents provided useable actigraphy data.
will be worn on the right hip for seven consecutive days to monitor physical activity and gives activity counts as output [ 29].
Subjects will wear the accelerometer fastened with an elastic strap to the right side of the waist for seven consecutive days with habitual physical activity, except for bathing and performing activities in the water.
Prior to each clinic visit, participants will complete a 3 consecutive day record of their physical activity and dietary intake.
Participants wore accelerometers (GT3X+ or ActiTrainer; ActiGraph LLC, Pensacola, FL, USA) on the left or right hip at all times, except when showering, swimming and sleeping, for 7 consecutive days to objectively assess physical activity levels.
