The Effects of Job Instability and Financial Strain on C-Reactive Protein in a Sample of Mexican Immigrants

Le résumé fourni par la source

OBJECTIVE: Mexican immigrants have lower cardiovascular disease risk than US citizens, but risk increases with level of acculturation. Our study investigated whether job stress and financial strain would be related to inflammation (C-reactive protein), lipids, and blood pressure, and if they would play a role in the acculturation process in Mexican immigrants. METHODS: A sample of 310 Mexican immigrants living in the United States were studied on measures of job stress, financial strain, acculturation, and cardiovascular disease risk factors (C-reactive protein, lipids, and blood pressure). RESULTS: Job instability, financial strain, and acculturation, were related to inflammation, but psychological demands and decision latitude were not related. Lipids and blood pressure were not related to the variables of interest. Body mass index (BMI) was related to both increased acculturation and inflammation, and when controlling for BMI, acculturation was no longer a significant predictor of inflammation. Job instability and financial strain remained significant predictors of inflammation after controlling for BMI, sex, and age. Job instability and financial strain were not related to acculturation, suggesting that these factors are significant stressors for both newly arrived and more established immigrants. CONCLUSIONS: Job instability and financial strain predict increased inflammation in Mexican immigrants but they do not play a role in the relationship between acculturation and C-reactive protein. The effects of acculturation on inflammation in this study were mediated by BMI.
