PURPOSE
The purpose of this study was to compare obesity-related quality of life according to obesity classification by BMI (body mass index) and self-assessment.
METHODS
The participants were 286 female college students in J City. Data were obtained by measuring height, weight and BMI, and using a questionnaire for self-assessment of obesity, weight control, and quality of life. The quality of life was measured using 14 items of the Korean version of obesity-related quality of life (KOQOL).
RESULTS
Thirty five percent of the students assessed themselves as overweight and obese despite their BMI <23m2/kg(false overweight). True overweight students with BMI > or =23m2/kg who perceived themselves as overweight and obese were 23%. The total KOQOL score between true and false overweight students showed no significant difference. True overweight students had a lower total KOQOL score including psychosocial, physical, daily living, sex related, and food-related domains than true normal weight students.
CONCLUSIONS
The quality of life was not different between true and false overweight students. These results indicate that self-assessment about obesity affects the quality of life like as actual BMI in female college students. Therefore, it is necessary to care students who distort themselves as obese.

AbstractAbstract PDF
PURPOSE
The purpose of this study was to validate waist circumference (WC) and waist to hip ratio (WHR) corresponding to body mass index (BMI) of 25kg/m2 and to survey the prevalence of hypertension according to obesity in female college students.
METHOD
Weight, height, waist and hip circumferences and blood pressure were measured for each of 286 female college students in J City, Chungbuk.
RESULTS
The subjects' mean BMI was 21.4kg/m2, and the estimated prevalence of obesity was 11.2%. The subjects, the 80th-90th percentile of whom had BMI exceeding 25kg/m2, were found to have WC of 75-78.1 cm and WHR of 0.79-0.80, respectively. Of the subjects with obesity(BMI> or =25kg/m2), 53.1% exhibited abdominal obesity (WC> or =80cm) and 40.6% had WHR over 0.80. Systolic and diastolic blood pressure were correlated with BMI, WC, and WHR. The prevalence rate of hypertension in subjects with obesity(BMI> or =25kg/m2) was 25%. Additionally, the prevalence rate of hypertension in subjects with abdominal obesity (WC> or =80cm) was 39.1%.
CONCLUSIONS
Our study indicates that WC corresponding to BMI of 25kg/m2 in female subjects in their twenties is different from that of adult women. We also found that the prevalence rate of hypertension in subjects with abdominal obesity was high. Therefore. we suggest further studies to determine the cutoff value of WC for evaluating abdominal obesity and to investigate the long-term effects of obesity on women in their twenties.
