Sleep disparities among US Latinos may be shaped by acculturation, but the complexities remain unexplored. With regression and latent class methods, we examined cross-sectional associations between multidimensional acculturation and self-reported sleep among an intergenerational Latino cohort in Sacramento, California: N=1716 older generation 1 (GEN1; Sacramento Area Latino Study of Aging) and N=670 middle-age generation 2 (GEN2; Niños Lifestyle and Diabetes Study) participants. GEN1 of high US acculturation reported better sleep: less restless (prevalence ratio[95% confidence interval] (PR[95%CI]): 0.67[0.54, 0.84]) and better overall (odds ratio[95%CI]: 1.62[1.09, 2.40]), but higher socioeconomic position (SEP) GEN1 reported more fatigue (PR[95%CI]: 1.86[1.11, 3.10]). GEN2 of stable-high intergenerational US acculturation reported shorter sleep (PR[95%CI]: 2.86[1.02, 7.99]). US acculturation shaped sleep differentially by generation and SEP: better among older lower SEP Latinos, but worse among higher SEPs of middle- and older age. Prospective intergenerational study designs should seek to elucidate underlying sociobehavioral pathways to inform intervention efforts.
