Abstract :
Background: Physical activity (PA) is associated with the metabolic
syndrome (MetS) and its components. This study aimed to examine
the association between PA and MetS and its components among
normal weight and overweight/obese adolescent in Tehran Lipid
and Glucose Study (TLGS).
Methods: This cross?sectional study includes 777 adolescents,
aged 12?18 years, who were selected by multi?stage random cluster
sampling from among TLGS participants. Subjects were classified
as normal weight and overweight/obese based on the age? and
sex?specific standardized percentile curves of BMI for Iranian
population. Levels of PA were assessed using a standardized and
modifiable activity questionnaire (MAQ), and categorized into
tertiles. MetS was defined according to the Cook’s criteria.
Results: Prevalence of the MetS was higher in overweight/obese
than normal group (35% vs. 3%; P: 0.02). Normal groups were
more physically active (50% vs. 44%); however, difference was not
significant. There was a significant association between the light
PA and risk of lower level of HDL?C before and after adjustment,
in normal weight group (OR: 1.61, CI 95%: 1.11, 2.35; OR: 1.65,
CI 95%: 1.12, 2.44, respectively). The overweight/obese group
with light and moderate PA had a higher risk of having abdominal
obesity than those with vigorous PA, only after adjustment for
determined covariates (OR: 1.11, CI 95%: 1.07, 1.21; OR: 1.06,
CI 95%: 1.01, 1.08, respectively); the association between MetS
and PA was not significant.
Conclusions: The results of this study confirm the association
between PA and some individual components of MetS such as
waist and HDL?C.
