| Summary: | Background. To
evaluate insulin resistance of normal weight
central obese 13–18-year-old male and
female adolescents stratified by waist to height
ratio (WHR). Methods. Data were
obtained from the Korea National Health and
Nutrition Examination Survey (K-NHANES) conducted during
2008–2010. Central obesity was defined as
that in the upper quartile of age and sex
specific WHR. Subjects were classified into no
central obesity normal weight (NW), central
obesity normal weight (CONW), no central obesity
overweight (OW), and central obesity overweight
(COOW). Results. The prevalence
of CONW was 9.6% (83/832) in female and
7.0% (61/909) in male. CONW showed higher
levels of insulin
(P<0.006),
HOMA-IR
(P<0.006),
and ALT
(P<0.001)
than NW in female. CONW had higher levels of
insulin
(P<0.0001),
HOMA-IR
(P<0.0001),
and WBC count
(P<0.021)
and lower level of HDL
(P<0.0001)
than NW in male. WHR and BMI had similar
significant correlations with MS components.
CONW showed 2.5 times (95% confidence
interval, 1.21–5.00) more likelihood to have
high insulin resistance than NW in male.
Conclusions. Screening for
central obesity using WHR in clinical setting is
recommended. |
