Objective: The study was carried out in order to determine the prevalence
of the overall and abdominal obesity by using together body mass index
(BMI) for age z-score, measurements of waist circumference and waist-toheight ratio in healthy Turkish adolescent girls.
Methods: A cross-sectional study was conducted on a total of 1112 adolescent girls aged 12 to 18 years old. Subjects were classified into four
categories of BMI for age z-score (WHO, 2007 for 5–19 years old): underweight, normal, overweight and obese in accordance with the cut-off
points (≤-2SDs to 1SD, –1SD to 1SD, 1SD to 2SD and ≥2SDs z-scores,
respectively). Abdominal obesity was defined according to WC≥ 90th
percentile for Turkish adolescent population references and WHtR ≥ 0.5.
Results: The prevalence of underweight 17.4%, normal weight 68.5%,
overweight 12.1% and obese 2.0% were found. A total of 16.9% subjects
were found abdominal obese based on WC≥90th percentile and 10.4%
based on WHtR ≥0.5. Abdominal obesity was higher based on WC than
based on WHtR. When evaluated four groups in terms of abdominal obesity status, prevalence was found 6.4% and 2.6% in underweight, 14.6%
and 5.8% in normal, 60.0% and 37.3% in overweight and 88.8 and 77.3%
in obese group according to WC and WHtR respectively. There were statistically significant difference between four groups both WC and WHtR
(p < 0.05). Both WC and WHtR was positively correlated with age r:0.332,
r:0.156, p < 0.05 respectively. There were significant positive correlations
between BMI values and WC measurements, WHtR in all ages.
