Effects of social support, imbalance of effort and reward, and sleep quality on self-rated health of male oil drilling crew workers in Southwest China.

Objective To analyze the current situation and potential influence paths of social support, imbalance of effort and reward, and sleep quality on self-rated health of male oil drilling crew workers in southwest China. Methods By using the method of cluster sampling, 1 951 male oil drilling crew workers were investigated, and a structural equation model was established to analyze the effects and pathways of social support, imbalance of effort and reward, and sleep quality on self-rated health. Results The average score of social support of the sample population was 38.13 ± 9.02, 53.0% was with low reward, the average score of sleep quality was 6.39 ± 3.72, and 47.8% of the workers rated their health as average/relatively poor/poor. The results of structural equation model showed that social support β = 0.123, 95%CI: 0.080-0.166) and sleep disorder (β =-0.407, 95%CI: -0.447 to -0.364) respectively had a direct effect on self-rated health. The mediating effect of sleep disorder and its chain intermediary effect on effort and reward imbalance were 0.008 (95%CI: 0.006-0.010) and 0.005 (95%CI: 0.004-0.006), respectively. Conclusion The social support, effort and reward, sleep quality, and self-rated health status of male oil drilling crew workers in southwest China are poor. Social support and sleep disorder have a direct effect on self-rated health, and the imbalance of effort and reward and sleep disorder play an intermediary role in the effect of social support on self-rated health.
