Patients attended a baseline assessment at the university.
Informed consent was taken, questionnaire measures of diet and
psychosocial variables were completed, and height and weight
were measured. Patients in Phase One recorded their daily
pedometer step count for three days before the intervention. For
Phase Two, accelerometers were worn for seven days before the
intervention to generate both step counts and time spent in PA.
Blood samples were taken for vitamin assays of ascorbic acid
(Vitamin C), plasma alpha-tocopherol (Vitamin E) and plasma beta-
carotene. On completion of the intervention, patients attended a
follow-up assessment using the same assessment protocol. All
those in Phase One and a sub-sample from Phase Two completed
telephone interviews to explore intervention acceptability.
