Social health, defined as a form of mental, individual, and social well-being, leads to citizens having high motivation and enthusiasm when it becomes a reality in society. Ultimately, this results in a healthy and vibrant community. The purpose of this research was to investigate the role of social factors affecting the social health of Tabriz citizens. Based on this, the impact of five social variables: social support, social trust, religiosity, social and economic base and the participation in social networks on social health was investigated. Also, determining the relationship of nine contextual variables with social health was another goal of this research. This paper utilizes Kinzer’s theories and employs a survey-based research method, using questionnaires to collect data. The sample size was 400 people, and a combination of stratified and cluster sampling methods was used. The results indicate that the average social health of citizens in Tabriz is slightly higher than the national average. Among the variables, social trust, religiosity, and social support significantly impact citizens’ social health. Only two variables, economic and social status, and participation in social networks, did not have a significant relationship with citizens’ social health. Evaluating the effects of direct and indirect influences, social trust, education, religiosity, and age respectively have the most significant impact on the social health of Tabriz citizens.
