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.
