Abstract
This quasi-experimental research with a two-group pre-post test design aimed to examine the effects of a health behavior change program combined with the health application use on body mass index and waist circumference in overweight and obese nursing students. A Volunteer sampling of 40 participants was divided into two groups. The experimental group received the health behavior change program developed based on Cox’s interaction model of client health behavior, combined with the health application was used to adjust diet and physical activity. The control group received the weight control manual developed by the researcher. The intervention lasted 12 weeks. Data were collected using personal information questionnaires, health behavior assessments, and measurements of weight and waist circumference. Data were analyzed using descriptive statistics for percentages, frequencies, means and standard deviations. The statistics used in this study were Independent t-test, Paired t-test, Wilcoxon signed-rank test, and Mann-Whitney U test.
The results showed that the experimental group had significantly better scores in health behaviors post-intervention compared to those of the control group (p = .001, p = .000). The experimental group showed a significant decrease in mean BMI of 1.48 kg/m² while the control group showed an increase of 0.25 kg/m² (p=.000, p=.001). Similarly, mean waist circumference in the experimental group decreased by 1.57 cm compared to a decrease of 0.15 cm in the control group (p=.000, p=.001). These results reflect the effectiveness of the health behavior change program in reducing BMI and waist circumference.
