Abstract
BACKGROUND
Survivors of childhood acute lymphoblastic leukemia and lymphoma (ALL/LL) are at risk for cognitive dysfunction, but little is known about its relationship with language proficiency and sociodemographics.
PROCEDURE
In this cross-sectional cohort study of Latino survivors of childhood ALL/LL, English and Spanish language proficiency and cognitive and academic functioning were measured and their associations determined using paired t-tests, Pearson correlations, and linear regressions.
RESULTS
Participants (N = 57; 50.9% female) had mean ages (years ± SD) of 4.3 ± 2.6 at diagnosis and 10.6 ± 2.9 at testing (range 6-16); mean time post treatment was 3.7 ± 2.6 years. The majority (73.7%) had low socioeconomic status (SES). Most (78.8%) were dual-language learners in English and Spanish. English proficiency was graded as limited-to-fluent and was significantly higher than Spanish (p < .001). Higher SES was correlated with higher English proficiency (r = 0.31, p = .020). Males had higher Spanish proficiency (r = -0.32, p = .034). Controlling for SES and sex, English proficiency accounted for 43% of cognitive functioning variance (F = 14.86, p < .001), 55% of reading comprehension variance (F = 22.14, p < .001), and 21% of mathematics variance (F = 5.76, p = .002).
CONCLUSIONS
Low language proficiency correlated with SES but was independently associated with lower cognitive and academic functioning. Research and surveillance for neurocognitive late effects in Latino ALL/LL survivors should incorporate measures of language proficiency and SES to account for their effects on cognitive and academic functioning.
