Abstract
There are several weight control methods for obese patients; but mainly behavioral modification;diet; exercise and drug therapy are being used. Behavioral approaches are based on the assumption that to lose weight; patients must decrease their caloric intake and increase their caloric expenditure. Toward this goal; behavioral approaches try to make patients be aware of their current intake and daily activities by having them record their behaviors on a daily basis. It is also possible to maintain reduced weight by behavioral changes accompaning by constant contacts with a therapist. The purpose of this study was to assess the effect of multidisciplinary education; including behavioral modification and drug therapy on body weight reduction; and to assess the effect of constant contact with therapist for control of reduced weight during maintenance period of reduced weight. From October to December 1996;the study subjects were 21 patients who completed weight reduction program for 8 weeks in the Department of Family Medicine; Dongsan Medical Center. The study subjects were divided into two group. In one group; a therapist interviewed obese patients individually; and educated about diet habit; food diary; behavioral changes. The other group; education and drug therapy (fluoxetine 40 mg/day) were done. After 8 weeks of weight reduction program; they were in contact with therapists and educated about weight maintenance program in regular 2 weeks interval for 16 weeks. At 6 months after initiating therapy; body weight was checked. Those who didn't revisit for follow-up check were evaluated by telephone questonaires After weight reduction program for 8 weeks; the mean weight change was -2.2土1. 09kg in education group; -2.9土 1.88kg in combined education and drug therapy group. There were no significant differences. During maintenance program of reduced weight; weight changes according to the frequency of visit for contact with therapist were significant difference(p< 0.05). In the charge of BMI(Body Mass Index); there were also significant differences in each visit group. In the weight reduction program; the important factor affecting weight reduction was activity; and in weight maintenance program; was constant contact with therapist and patient's age. During 6 months (including weight reduction and maintenance program); a change of weight in completed contact group with therapist is larger than not completed contact group with therapist.
