BACKGROUND: Chinese American breast cancer survivors’ adherence to recommended physical activity (PA) guidelines has been understudied. This study investigated their PA adherence by acculturation level (vs. non-Hispanic White (NHW) survivors). METHODS: 195 Chinese and 202 NHW breast cancer survivors (stage 0-III) responded to a cross-sectional survey including a self-reported PA questionnaire. PA adherence referred to meeting PA recommendations for cancer survivors. Acculturation among Chinese was defined by proxies of U.S. residency, English proficiency, and interview language. Logistic regression was performed to examine factors associated with PA adherence. RESULTS: More-acculturated Chinese survivors’ PA adherence rate was 76%. Less- acculturated Chinese survivors’ adherence rate (60%) was significantly lower than that of NHWs (80%) (OR = 0.38, 95% CI = 0.19, 0.75). Less-acculturated Chinese survivors were also less likely to engage in vigorous-intensity PA than NHWs. (p

Health literacy (HL) research among Hispanics currently focuses on individuals with limited English proficiency but impacts of HL on healthcare outcomes among other English language proficiency groups is relatively unknown. Regression models assessed associations between HL and healthcare outcomes for Hispanics overall (n = 4013) and for proficiency level sub-populations using the 2007 Pew Hispanic Health Survey. Overall, Hispanics with adequate HL percieved US medical care as “excellent,” were more satisfied with their doctor’s help, and reported “excellent” overall health. In the sub-population analysis, “excellent” perception of US healthcare was associated with HL among the Spanish and English dominant groups. Among bilinguals, adequate HL was associated with decreased use of traditional medicine. The effect of adequate HL varied within English proficiency groups. HL research that focuses only on Spanish dominant speakers can exclude a substantial percentage of English proficient or bilingual populations who have low HL.
