Effects of Self-Management Program for Health Behavior Modification in Group of Hospital Personnel with High Body Mass Index and Waist Circumference, Chiangrai Prachanukroh Hospital, Chiang Rai Province

Abstract

This study was a historical control design aimed to examine the effects of a self-management
program on health behavior of personnel with excessive weight, body mass index (BMI) and waist
circumference at Chiangrai Prachanukroh Hospital, Mueang District, Chiang Rai Province. The samples
were hospital staff members with excessive weight, BMI, and waist circumference in the fiscal year
2023. A total of 132 participants were purposively selected to compare pre- and post intervention, data
following participation in the change size, lose belly program, which was based on a self-management
approach. Data were analyzed by using descriptive statistics and paired t-tests. The results indicated
that after participating in the program, the average health behavior scores of the participants were
significantly higher than before (p<0.05). Health outcome measures, including BMI, waist circumference,
triglycerides, and low-density lipoprotein levels, also significantly decreased compared to before the
program (p<0.05). In summary, the self-management program enhanced participants’ self-management
skills, leading to improved health behavior changes, and effectively controlled weight, waist circumference,
BMI, and laboratory results to within normal ranges. The program can be applied to patients with
excessive weight, waist circumference, and BMI beyond standard thresholds. Ongoing follow-up and
application of this approach in health promotion and behavior modification in normal, at-risk, and chronic
disease groups are recommended.
