A cross-sectional study was conducted to determine the physical activity levels of 400 adolescents (13 years old) in Kuantan, Pahang using the Physical Activity Questionnaire for Older Children (PAQ-C). The associations of physical activity levels with sex, ethnicity and body mass index were also determined. About one third (35.3%) of the adolescents were in the low physical activity level category, 61.5% in the moderate physical activity level and only 3.0% of the adolescents were in the high physical activity level category. More males (77.9%) were physically active than females (54.9%). Twice as many female adolescents (45.1%) were in the low physical activity level category compared to the male adolescents (22.1%). The associations between physical activity with ethnicity and body mass index were not significant. However, there was a significant interaction effect of sex and ethnicity in mean physical activity score (F = 2.36, p<0.01). Malay males had a significantly higher mean physical activity score as compared to Chinese males (t=2.13; p<0.05). Although Chinese females had a higher mean physical activity score than Malay females, the difference was not statistically significant. Conversely, there was no interaction effect of sex and BMI status in mean physical activity score. This study suggests that physical activity intervention to promote regular physical activity is needed since a high proportion of the adolescents fall within the low physical activity level category.
