Overweight among school-aged children is an important global health problem. The modification of eating, physical-activity behaviors can help to normalized body weight. This quasi-experimental study was aimed to examine the effects of a weight control program on eating, physical-activity behaviors, and bodyweight among overweight, late school-aged children by using Health Belief Model. The sample consisted of 54 children aged 10-12 years old and their guardians. They were selected according to the inclusion criteria and randomized sampling technique was used for allocating them to experimental and control groups (27 each). The weight control program was implemented with the experimental group, while the control group received only usual care. The instruments were a weight control program and eating, physical activity behavior questionnaires. Data were analyzed using descriptive statistics and independent t – test.
The results showed that after the experiment, the mean score of eating behavior in the experimental group was higher than those in the control group with a statistical significance of p < .05. The mean score of physical-activity behavior in the experimental group was higher than those in the control group was not statistically significant (p < .05). Body weight mean of the experimental group was lower than the control group with a statistical significance of p < .05. The results show the effectiveness of a weight control program that can be used to modify behaviors to stay healthy.
