Cardiovascular risk and access to primary care: Comparisons among Chinese documented and undocumented immigrants

Aims The aim of this study was to examine main risk factors of undocumented Chinese migrants living in Italy when compared with Chinese migrants registered with National Health Service (NHS). Methods A cohort of 3435 Chinese first-generation immigrants living in Prato underwent blood pressure (BP) measurement and blood tests. Hypertension was diagnosed for BP ≥ 140/90 mmHg at 2 visits, and/or antihypertensive drug use; type 2 diabetes (T2DM) for fasting glucose ≥ 126 mg/dL at 2 visits, and/or use of hypoglycemic drugs; hypercholesterolemia (HC) for cholesterol ≥ 240 mg/dL and/or statins use. Subjects diagnosed with hypertension, T2DM, or HC unaware of their condition were considered newly diagnosed. Comparisons were performed using multivariable adjusted logistic regression analysis. Results A large proportion of Chinese migrants were undocumented (1766, 51 %); newly diagnoses of risk factors were performed especially among undocumented migrants; registration with NHS was associated with higher level of awareness for hypertension and T2DM and with 6 times higher rate of treatment for T2DM. Only a small minority of subjects with high cholesterol were treated with statins. Conclusions Undocumented immigrants had high prevalence of risk factors with lower levels of awareness than migrants registered with the NHS. Health policies targeting this hard-to-reach population needs to be improved.
