Background
: In evaluation and managing obese patients, it is more important to assess obesity itself as well as the associated disease than to focusing on reduction of body weight alone. Our study was carried out to identify the characteristics of hypertension and hyperlipidemia.

Methods : We selected obese adult patients over twenty who visited the obesity clinic at Asan Medical Center. Questionnaire was given on medical history, eating behavior, food frequency, activity degree and so on. we collected the 233 data of questionnaire and medical records, and analysed the characteristics of hypertension, hyperlipidemia.

Results : The frequency of hypertension and hyperlipidemia was higher in men than women. but that of binge eating was higher in women than men. For men, waist circumference was significantly higher in hypertensive group with 108.9±12.7cm than normotensive group with 101.2±9.1cm (p<0.05). For women, there were trends for increased frequency of hypertension and hyperlipidemia with age, and decreased frequency of binge eating with age (p<0.05). The BMI was significantly higher in female hypertensive group with 30.8±5.4kg/㎡ than in normotensive group with 29.4±3.2kg/㎡ after adjusting for age.

Conclusion : The accompanying health problems with obesity depend on gender, age, distribution of adiposity and nutritional intake. In evaluating obese patients, it should be stressed to assess co-morbidity and associated factors, and to manage comprehensively.
