Heart failure (HF), a long term outcome of chronic methamphetamine use (MU), occurs more frequently in racial and ethnic minority populations at high risk for cardiovascular disparities. This study examined the association of socio-demographic and clinical risk factors with MU among heart failure patients who are Native Hawaiians (NH) or other Pacifi c Island peoples (PIP). Design/Setting/Patient population: Cross-sectional study of NHs and PIPs with advanced heart failure enrolled in the Malama Pu’uwai Study, a randomized control trial to test an educational intervention to reduce re-hospitalization and/or death. A total of 82 participants were enrolled between 6/1/06 to 12/31/07 and met the following eligibility criteria: 1) self-identifi ed NH or PIP, 2) Left ventricular systolic ejection fraction 45%, 3) Age of 21 years or older. Data were analyzed by odds ratios (OR), 95% confi dence intervals (CI), and multiple logistic regression analysis. Main outcome measure: Methamphetamine use. Results: Twenty-two percent of HF participants were identifi ed as being current or prior methamphetamine users. Younger age and non-married status (combined never married or divorced/separated) were independently associated with MU after adjustment for sex, education, and other co-morbidities associated with HF (ie, age 50 years, OR = 0.16, 95% CI, 0.03–0.84; non-married status combined as never married OR = 8.5, CI, 1.5–47; divorced/separated OR = 11, CI 1.8–75). Conclusions: Risk factors associated with MU in NH and PIPs with heart failure include: younger age and being divorced/separated or never married. Health care providers should be aware of MU as a contributing factor in the approach and treatment of HF in NHs and PIPs.
