Tracking of Pedometer-Determined Physical Activity: A 10-Year Follow-Up Study From Adolescence to Adulthood in Sweden

• BACKGROUND: Tracking refers to the tendency for an individual to maintain their rank within a group over time. AIM: To identify levels of pedometer determined physical activity and explore tracking over ten year follow up period. METHODS: In October of 2000, 2003, 2005 and 2010, data of physical activity as steps/day was measured with Yamax SW-200 Tokyo, Japan for four consecutive schooldays in 40 (19 females) Swedish individuals (mean age 12.7 in 2000). RESULTS: In boys a decrease of mean step/day occurred between baseline and the three year (p < 0.001), the five year (p < 0.001) and the ten year follow-up (p < 0.014). A significant moderate tracking occurred in those at baseline classified insufficient active, both over the 3-5 year (rs = 0.56, p = 0.005) and the 0-10 year span (rs = 0.47, p = 0.05). CONCLUSION: The significant decrease of physical activity, as steps/day, in males at early adolescent seems to level out during late adolescence and early adulthood. Further, youth classified insufficient active according to published BMI reference standards at the baseline measures showed a significant moderate tracking over the ten year follow-up period.
