摘要

Obesity is related to the development of many chronic diseases. It is well-known that body weight (BW) reduction can be beneficial for the prevention against several chronic diseases. In general, it's easily practical to reduce BW, but maintaining the reduced-BW is difficult. Many studies have suggested that it can be the way to maintain the BW by having higher self-efficacy and good eating behaviors, which were acquired probably through the nutritional education. To investigate the differences of self-efficacy, eating behaviors, and the BW maintain between the individualized and the group nutritional educations, sixty-five overweight subjects were randomly divided into three groups, the control (n=20) group, the INE (individual nutritional education, n=22) group, and the GNE (grouping nutritional education, n=23) group. The entire study had 8-months duration including 2-months course for weight-reduction and the 6-months follow-up for bodyweight maintenance. Subjects' body composition, self-efficacy and eating behaviors were analyzed at 0 (baseline), 2 (weight-reduction), and 8 (the follow-up) months. The data showed that there were no significantly difference in baseline self-efficacy and eating behaviors among these three groups. The INE and the GNE groups have higher degree of self-efficacy and good eating behaviors at 2 month while compared with that at baseline (P＜0.05). Compared to the GNE group, the INE group had higher healthy degrees of lipid, carbohydrate, positive and negative eating behaviors. After the follow-up, the observation which the percentages of lasting weight-reduction in the control, the INE, and the GNE groups were 35%, 68%, and 57% showed the INE group or the GNE group is more easy to keep the BW reduced when compared to the control group. This study suggested that the INE and the GNE both benefit to gain self-efficacy and healthy eating behaviors, to reduce BW, and to keep the BW reduced. While compared to the GNE, the INE had higher degree of healthy eating behaviors in the duration of weight-reduction and more practical to keep the BW reduced in the duration of maintenance.
