Background
: Obesity is a very important and serious health problem because it itself is no only the independent risk factor of coronary heart disease. But it is also related to many other disorders and increased mortality rate. The purpose of this study is to assess the effects of multidisciplinary educations, including behavior modification, diet therapy, and exercise, on body weight reduction in obese patients.

Methods : The study subjects were eighty-four in number who visited to Obesity Clinic of AMC from Oct. 1991. to May. 1992. Observations for body weight changes were carried on after five months period to whom previously received individualized multidisciplinary educations for each behavior modification, diet therapy, and exercise. Those who did not revisit for follow-up were evaluated by telephone questionaires.

Results : Among 71 subjects in whom follow-up evaluations were possible, the number of male and female patients were 15 and 56, respectively.
Changes in body weight after five months of treatment showed the statistically significant reduction in both sexes, from 84.0±10.1kg to 80.9±9.2 kg in males and 71.4±8.8 to 69.0±9.2 in female. (P<0.05) Eleven(76.3%) among the males and forth-three(76.8%) among the female showed weight reduction. There were no significant differences of sex, age, marital status, occupations, educations, socienomic status, familial history, and disease history between weight reduction group and non-reduction group. The results of weight reduction according to grading scale are as follows: One male(9.1%) and two female patients(4.7%) for over 10kg loss, two male(18.2%) and four female patients(9.3%) for between 5 to 10kg loss, eight male(72.7%) and thirth-seven patients(86.0%) for less than 5kg of loss. There were differences in weight reduction between group that did behavior modification and that did not(P<0.05). also differences between group that did diet therapy and that did not(P<0.05) by univariate analysis, but no statistical significance by multivariate analysis. There is no difference in weight reduction between group that did exercise and that did not(P<0.05)

Conclusion : We observed the effects of behavior modification, diet therapy, and exercise on weight reduction in obese patients and results are significant weight reductions favorable for both sexes(3.0±3.5kg in male and 2.3±3.4kg in female). Eleven male(73.4%) and forth-three(76.8%) female showed weight reduction.
