Abstract

Objectives: To investigate pedometer-assessed physical activity, self-report screen-time and weight status of suburban and semi-rural Malaysian adolescents

Methods: A total of 313 adolescents (100 boys, 213 girls), mean age 13.5 ± 0.52 year, predominantly Chinese (57.2%), Bidayuh/Iban (33.9%), Malays (7.3%) and others (1.6%), provided 7-day pedometer data. Differences in step counts, screen-time and anthropometric data across gender, ethnicity, locality and weight status were examined.

Results: Analyses identified 25.3% (girls -14.4%; boys - 10.9%) were overweight and obese, with only 5.1 % achieved pedometer-activity guideline. The accumulated mean (SD) steps/day was 7234 ± 3463 (boys) and 6385 ± 2343 (girls). The mean (SD) for screen-time was 3.20 ± 1.74 hour/day. Step counts were the same across locality. Boys had significantly more steps (p=0.020), accumulated on weekdays (p=0.021) during schooling time compared to girls. A decrease of activity on weekends was evident. Mann-Whitney U test for pair wise comparisons revealed that overweight and obese adolescents are significantly taller and heavier than normal weight adolescents; and the Bidayuh/Iban significantly more active than the Chinese and the Malays (p <0.05).

Conclusion: This study suggests the promotion of physical activity and limitation of screen time should target non-schooling time particularly on weekends when adolescents are severely inactive.
