Isolated by language and cultural beliefs, Chinese immigrants face formidable barriers to receiving appropriate health care services. In the absence of preventive care, common treatable disease such as high blood pressure (BP) becomes much more dangerous and severe. OBJECTIVES: Assess trends in the prevalence, awareness, treatment, and control of hypertension among Chinese immigrants in New York City (NYC). METHODS: Using a standardized survey, BP measurements and health information of participants aged 18 years or older were collected during a series of community health fairs in various Chinese communities. The 2001-2002 survey (N=668) was compared to 2003-2004 survey (N=791). Hypertension is defined as a measured BP of >140/90 mm Hg or reported use of antihypertensive medications. Hypertension awareness and treatment were assessed with standardized questions. Hypertension control was defined as reported hypertension with or without antihypertensive treatment and a measured BP of <140/90 mm Hg or <130/85 mm Hg for diabetics. RESULTS: In 2003-2004, 44% of participants had hypertension, a decrease of 5% (p=0.058) from 2001-2002. Hypertension prevalence was higher in women (25%) and increased with age (31% among those aged >60 years). In a Pearson correlation analysis, increasing age and decreasing exercise were independently associated with increased rates of systolic blood pressure (SBP) but not diastolic blood pressure (DBP); increasing body mass index was independently associated with increased in both SBP and DBP. Overall, in 2003-2004, 71% were aware of their hypertension (a decline of 1%; p<0.737), 26% were treated (decrease of 8%; p=0.017), and hypertension was controlled in 40% (increase of 2%; p=0.645). Men and those aged 40-59 had lower rates of hypertension treatment and control compared with women and the older individuals. CONCLUSIONS: Although prevalence and control rates of hypertension are improving, hypertension control rates continue to be low. Expanded effort is needed to improve BP outcomes.
