title: Four-week pedometer-determined activity patterns in normal-weight, overweight and obese adults.
abstract: OBJECTIVE
  To assess pedometer-determined ambulatory activity in normal-weight, overweight and obese UK adults.
  
  
  METHODS
  Eighty-six normal-weight (BMI <25 kg/m(2)) (age=34+/-12.1 years), 91 overweight (BMI 25-29.9 kg/m(2)) (age=40.6+/-13.6 years) and 75 obese (BMI >or= 30 kg/m(2)) (age=41.2+/-12.4 years) participants, from the East Midlands, provided 4 weeks of continuous pedometer-determined activity data, during the winter in 2006. Activity levels and patterns were assessed for all three groups.
  
  
  RESULTS
  The normal-weight group had a significantly higher mean step count (10247 steps/day) than the overweight (9095 steps/day) and obese (8102 steps/day) participants (p<0.05). No differences in step counts were observed between the overweight and obese groups. A consistent reduction in activity was observed on Sundays in all groups, with this reduction being two-fold greater in the overweight and obese groups (approximately 2000 steps/day) when compared with the normal-weight group (approximately 1000 steps/day).
  
  
  CONCLUSIONS
  With the increasing prevalence of obesity in the UK, changes in the activity levels of those at risk are needed. The issuing of pedometers to overweight and obese individuals, with the instruction to increase their ambulatory activity on all days of the week, with particular emphasis on Sunday activity, could be a good starting point in tackling the problem of obesity in the UK.
