Migration is a very stress-inducing phenomenon. During the migration process, an overreaction of the autonomic nervous system due to a chronic, unexpected, or non-modifiable stressor can precipitate cardiovascular dysregulation. However, the effect of migratory stress on cardiovascular disease remains unclear. The study population consisted of migrant subjects who were seen at Ansan Vincent’s Free Clinic between July 2004 and January 2008. Among subjects who were interviewed by a social worker, 510 (282 males, mean age 42±12 years) were enrolled in this study. Men were more frequently employed than women (p<0.0001). The most common reasons for presenting to the clinic were orthopedic problems (24.8%), followed by respiratory problems (14%), including the common cold. The patients were divided into two migration groups based on a period of three years. The incidence of HBP between the two groups was similar. After adjusting for cardiovascular risk factors, the migration period correlated with SBP [β =1.066, 95% confidence interval (CI) 1.013-1.122, p=0.014] and PP (β=1.057, 95% CI 1.010-1.107, p=0.016). In conclusion, migrants with cardiovascular disease have a risk factor of developing vascular change resulting from disturbances caused by differences in repetitive, social and cultural stimuli. Further studies are required to confirm this.
Abstract
Migration is a very stress-inducing phenomenon. During the migration process, an overreaction of the autonomic nervous system due to a chronic, unexpected, or non-modifiable stressor can precipitate cardiovascular dysregulation. However, the effect of migratory stress on cardiovascular disease remains unclear. The study population consisted of migrant subjects who were seen at Ansan Vincent’s Free Clinic between July 2004 and January 2008. Among subjects who were interviewed by a social worker, 510 (282 males, mean age 42±12 years) were enrolled in this study. Men were more frequently employed than women (p<0.0001). The most common reasons for presenting to the clinic were orthopedic problems (24.8%), followed by respiratory problems (14%), including the common cold. The patients were divided into two migration groups based on a period of three years. The incidence of HBP between the two groups was similar. After adjusting for cardiovascular risk factors, the migration period correlated with SBP [β =1.066, 95% confidence interval (CI) 1.013-1.122, p=0.014] and PP (β=1.057, 95% CI 1.010-1.107, p=0.016). In conclusion, migrants with cardiovascular disease have a risk factor of developing vascular change resulting from disturbances caused by differences in repetitive, social and cultural stimuli. Further studies are required to confirm this.
