Cardiovascular Risk Factors and Knowledge of Symptoms Among Vietnamese Americans

Abstract

BACKGROUNDThere are few population-based studies of cardiovascular risk factors, knowledge, and related behaviors among Vietnamese Americans.OBJECTIVETo describe cardiovascular risk factors, knowledge, and related behaviors among Vietnamese Americans and compare the results to non-Hispanic whites.DESIGNComparison of data from two population-based, cross-sectional telephone surveys.PARTICIPANTSVietnamese Americans in Santa Clara County, California, and non-Hispanic whites in California, aged 18 and older.MEASUREMENTSSurvey measures included sociodemographics, diagnoses, body mass index, fruit and vegetable intake, exercise, and tobacco use. Knowledge of symptoms of heart attack and stroke was collected for Vietnamese Americans.MAIN RESULTSCompared to non-Hispanic whites (n = 19,324), Vietnamese Americans (n = 4,254) reported lower prevalences of obesity, diabetes mellitus, coronary heart disease, and hypertension, and similar prevalences of stroke and hypercholesterolemia. Fewer Vietnamese Americans consumed fruits and vegetables five or more times daily (27.8% vs 16.3%, p < 0.05), and more reported no moderate or vigorous physical activity (12.1% vs 40.1%, p < 0.05). More Vietnamese men than non-Hispanic White men were current smokers (29.8% vs 19.0%, p < 0.05). Vietnamese Americans who spoke Vietnamese were more likely than those who spoke English to eat fruits and vegetables less frequently, engage in no moderate or vigorous physical activity, and, among men, be current smokers. Only 59% of Vietnamese Americans knew that chest pain was a symptom of heart attack.CONCLUSIONSThere are significant disparities in risk factors and knowledge of symptoms of cardiovascular diseases among Vietnamese Americans. Culturally appropriate studies and interventions are needed to understand and to reduce these disparities.
