Background: A healthy lifestyle has become related to health status to a great extent, and it's the mainstay of preventive medicine. Unhealthy lifestyle habits can be modified, usually starting in youth and continuing throughout adulthood. Health professionals are presumed to have healthier lifestyle options and therefore their health outcomes are better due to higher health education and awareness, but what is actually known about their health outcomes in comparison to the overall population is little. Also, studies are limited regarding the healthy lifestyle among non-health professionals such as administrators and social workers in primary health care centers. Therefore, to address these health issues, this research aims to determine the prevalence of a healthy lifestyle as well as to identify the determinants affecting the adherence of a healthy lifestyle among governmental primary health care center workers in Jeddah, 2018. Methods: This research was a cross-sectional study conducted from October 2018 to June 2019 in Jeddah, Kingdom of Saudi Arabia. All workers except sanitary, security and pregnant workers from different governmental primary health care centers were chosen by stratified simple random sampling technique, participated by the use of a validated self-administered questionnaire. The dependent variables of the study included the four healthy lifestyle elements (smoking, diet, BMI and physical activity), while the independent variables included the socio-demographic data and the presence of any lifestyle-related chronic medical problem. Results: This research has included 200 participants from different governmental primary health care centers. The prevalence of smoking was 26.6%. The majority of the participants (75%) scored toward a healthy diet. Only 32% of the study population had a normal body mass index, and the mean physical activity score was 9.2 Conclusion: Governmental primary health care workers do not practice healthy lifestyle habits. Health promotion programs need to target workers in governmental primary healthcare centers in order to benefit their own health which ultimately lead to better role modeling and patient counseling, and therefore a better society. Keywords: smoking, diet, physical activity, BMI, workers.
