fa بررسی رابطه‌ی بین سرمایه‌ی اجتماعی و کیفیت زندگی مرتبط با سلامت در معلمان کارآزمایی بالینی Clinical Trials Backgrounds and Objectives: Different studies have shown a relationship between social capital and health. The aim of this paper was to survey about the relation between social capital and health-related quality of life (QOL) among teachers. Materials and Methods: In this cross -sectional study, our target community was 375 people that were selected by Multi-stage cluster sampling method. For assessment of Social Capital Onyx and Bullen (2000) were used, and for assessing health-related QOL SF-36 questionnaires were used respectively. Data were analyzed with independent T, ANOVA, Pearson correlation and Regression tests. Results: The mean age of respondents was 40.7&plusmn;5.26 and based on gender 51.9% of them were male. Mean and SD of total QOL and total social capital scores were 64.52&plusmn;17.02 and 71.21&plusmn;16.74 respectively. Pearson correlation test showed that there was a significant correlation between total social capital with total health-related QOL(r =0/153 p<0.004), cognitive social capital with physical health(r = 0/136 p<0.011) and also communicative social capital with mental health(r = 0/133 p<0.012). There was significant relationship between structural social capital and both dimensions of health-related QOL: physical health(r = 0/146, p=0.006) and mental health(r = 0/156, p=0.003). Also regression analysis showed that variables of &quot;gender&quot;, &quot;marital status&quot; and &quot;age&quot; have not impact on the relationship between social capital and QOL and have been removed from model, but &quot;income&quot; was an effective variable in the main relationship of the research. Conclusion: Our finding showed that there was positive correlation between social capital and health-related QOL among teachers. It appears that focus voluntary groups activities could increases trust and personal network, and its issue could improve mental and physical health of teachers.
