Abstract

Objectives: To examine the long-term effects of a new behavioral weight control program (Kenkou-tatsujin®, KT program). The program consisted of twice-interactive letter communications including computer-tailored personal advice on treatment needs and behavioral modification. Design: A randomized controlled trial comparing Group KM: KT program with 6-month weight and targeted behavior's self-monitoring, Group K: KT program only, Group BM: an untailored self-help booklet with 7-month self-monitoring of weight and walking, and Group B: the self-help booklet only. Participants: Two hundreds and five overweight Japanese females were recruited via a local newspaper. Measurements: Weight loss (body weight, BMI, reduction quotient, etc.) and behavioral changes (daily eating, exercise and sleeping habits). Findings: A significant weight loss was observed in all groups. At 1 month, Groups KM and K were superior, but at 7 months, the mean weight loss was significantly more in Group KM than the other 3 groups. At 7 months, 8 dietary habits and 4 physical activities were improved in all subjects. Habitual improvement was related to the weight loss in Groups KM and K at 1 month.
