Pedometer-assessed physical activity of Singaporean youths.
Preventive Medicine, 2010
OBJECTIVE: The aim of the study was to investigate the pedometer-assessed physical activity of Singaporean youths using an objective measurement of physical activity.
METHOD AND RESULTS: Pedometer step count was monitored over the entire week in 877 participants aged 9-18years in three schooling cohorts [primary (age 9-12yrs; n=150 male; 156 female), secondary (age 13-16yrs; n=137 male; 138 female) and junior college (age 17-18yrs; n=140 male; 156 female)] in Singapore during July to September 2009.
Analyses identified significant main effects for step count taken outside of school compared to within school (Mean (SD): 5568(4796) vs.
However no significant difference was found for steps accumulated within or outside school in boys and girls across the schooling levels (steps*sex*level interaction, p>0.05).
9483 (8056), p>0.05), across schooling levels and between male and female participants (sex*level and steps*level*sex interactions, all p>0.05).
CONCLUSION: Step count decline is drastic for male adolescents after primary school but remains low across the schooling levels for female participants.
Aggregated daily step count fell short by up to 35% of the 16000 and 13000 steps recommended respectively for male and female youths.
