Poster session presented at International Society for BehavioralNutrition and Physical Activity 2014, San Diego, United States.Trends in pedometer-measured steps per day in Danish adults: 2007 to 2012Methods• The study population comprised a random sample of Danish citizens aged18-75 years who participated in the Danish National Survey of Diet andPhysical Activity (DANSDA) in 2007-2008 (n=224) and 2011-2012(n=1515).• Sealed pedometer data (Yamax SW-200) were obtained for sevenconsecutive days.• A total of 1624 participants (48.2% men) met the inclusion criteria, i.e. atleast four valid days of data (≥ 10 h/d).• Regression models adjusted for sex, age, education and season wereused to analyse data.Table 1. Steps/day and percentages of active and sedentary adults (mean(95% CI)), DANSDA 2007-2008 (n=202) and 2011-2012 (n=1408)*P<0.05, **P<0.01: Differences between survey periods using regression modelsa160 step equivalents were added for each minute of cycling1Results• In 2011-2012, Danish adults took on average 8341 (95% CI 8160; 8523)steps/day.• A significant difference was observed between men and women in 2011-2012 (p=0.046). However, when cycling was taken into account nodifference between sexes was found (p=0.288).• Mean steps/day decreased by 446 from 2007-2008 to 2011-2012 (Table1).• The proportion taking ≥10,000 steps/day decreased and proportion taking<5,000 steps steps/day increased (Figure 1). These changes was primarilydue to a reduced level of activity among women as men maintained theiractivity level (Table 1).Figure 1.

Preliminary pedometer indices for public health. Sports Med 2004, 34:1-8.Conclusion This nationally representative survey showed a tendency to a decline in daily steps due to a lower level of activity among women. Theincreased proportion with a sedentary and low active lifestyle is worrying from a public health perspective. Targeted actions should encourage these individuals,especially women, to increase their level of physical activity.Introduction Objective measurements of physical activity havebeen lacking in Denmark. Therefore, little is known about the time trendsin the population.Purpose To examine temporal trends from 2007-2008 to 2011-2012in pedometer-measured physical activity (steps/day) in a nationallyrepresentative sample of Danish adults.0510152025303540Sedentary<5,000Low active5,000-7,499Somewhat active7,500-9,999Active10,000-12,499Highly active≥12,500Percent2007-2008 2011-2012All Men Women 2007-2008 2011-2012 2007-2008 2011-2012 2007-2008 2011-2012Steps/day 8788 (8321; 9254)8341 (8160; 8523)8648 (8015; 9280)8521 (8262; 8780)8968 (8291; 9645)8164*(7920; 8408)≥ 10,000 steps/day (%) 34.8 (28.3; 41.3)29.3 (26.9; 31.7)27.0 (23.8; 30.2)31.7 (28.1; 35.2)39.8 (30.2; 49.5)30.5**(22.0; 39.1)< 5,000 steps/day (%) 14.2 (9.2;19.1)16.4 (14.4; 18.4)17.6 (14.8; 20.3)15.3 (12.5; 18.0)13.1 (6.1; 20.1)14.9 (8.2; 21.7)Steps/day incl. cyclinga 9892 (9307; 10478)9583 (9355; 9810)9327 (8533; 10121)9705 (9381; 10030)10546 (9697; 11395)9468*(9162; 9774)
