dc.description.abstract | Physical activity (PA) behavior correlates with fatness in several distinct
populations.
Purpose:
To determine the relationship between sedentary
behaviour, PA and indices of body fatness in adolescents.
Methods:
Sedentary
behaviour
and
habitual PA in 200 adolescents (102 girls and 98 boys) aged 13
–
16
years (13 ± 1 years; mean ± SD) were assessed by accelerometry for 5 consecutive
days. Time in sedentary activities (<800 counts per minute (CPM) and light
>800<3200 CPM), moderate >3200<82
00 CPM) and vigorous >8200 CPM) PA
were calculated using Puyau cut
-
points. Indicators of body fatness were assessed
using ∑skin
-
folds (
ΣSF)
(triceps, biceps, sub
-
scapular and supra-iliac), Body Mass
Index (BMI) and waist hip ratio (WHR) and correlated with
sedentary and PA of different intensities.
Results
:
Time in sedentary activity was positively correlated
with BMI (r =0.44,
P<0.001
) and ΣSF (r = 0.21, P = 0.003). CPM and time spent
engaged in light, moderate and vigorous intensity activities were negatively
correlated with BMI and ΣSF. 16.1% of variation in ΣSF could be explained by
gender; R
2
= 11.4% and time spent engaged in sedentary activities, R
2
= 4.7%;
P<0.05.
Conclusion:
Time engaged in sedentary activity and PA was a significant
predictor of in
