Impact of a Multi-component Healthy Lifestyle Program on Job Performance Among Primary Healthcare Physicians in Tabuk City, Saudi Arabia: A Quasi-experimental Study.

Primary healthcare physicians play a vital role in delivering frontline medical services, yet they are frequently exposed to high levels of occupational stress, poor lifestyle habits, and demanding workloads, which can negatively impact their job performance and overall well-being. This study aimed to assess the impact of a healthy lifestyle program on job performance. This quasi-experimental study was conducted on 170 primary healthcare physicians in the Tabuk region, who were selected by a multi-stage sampling technique, between January 1, 2025, and May 31, 2025. Data was collected using face-to-face interviews. Physicians were assessed using a structured questionnaire and job performance questionnaire, anthropometric measurements were obtained, and body mass index (BMI) was calculated. This study showed statistically significant improvement in dietary habits, physical activity, average sleeping hours, and job performance at the end of the intervention than before (p<0.001). BMI was significantly reduced after the intervention (p<0.001). The implementation of a multi-component healthy lifestyle program resulted in statistically significant improvements in dietary habits, physical activity, sleep duration, and job performance. Additionally, a significant reduction in BMI was observed. So, these findings highlight the effectiveness of integrated lifestyle interventions in enhancing both the professional performance and overall well-being of healthcare providers.
