Purpose: This study aims to assess the racial health disparities in the healthrelated quality of life (HRQoL) among the U.S. Hispanic hyperlipidemia population with comorbidities Patients and Methods: This cross-sectional study used the 2014-2015 Medical Expenditure Panel Survey (MEPS) data. HRQoL measurement was done using the SF- 12 PCS and SF-12 MCS surveys. Inferential statistics comprising of chi square tests of differences and multivariate regression analyses were conducted to determine HRQoL in the U.S. residing Hispanic population with hyperlipidemia. The regression statistics were performed for both SF-12 PCS and SF-12 MCS surveys. Results: The study sample included 13,933 Hispanics residing in the U.S. out of which 14.2% (n=1,985) had hyperlipidemia. Controlling for covariates, U.S. Hispanics with hyperlipidemia had significantly lower SF-12 PCS (-3.85, SE=0.49; p<0.001) and SF-12 MCS (-2.77, SE=0.49; p<0.001) scores compared to U.S. Hispanics without hyperlipidemia respectively. The lone predictor for SF-12 PCS scores was age whereas marital status, high school education and poverty level were predictors for SF-12 MCS scores. Compared to U.S. Hispanics with no comorbidities, U.S. Hispanics with three or more comorbidities had significantly lower SF-12 PCS (-2.36, SE=0.28; p<0.001) and SF- 12 MCS (-2.59, SE=0.27; p<0.001) scores respectively. Conclusion: Further research is needed to understand the impact of chronic diseases including hyperlipidemia, type 2 diabetes, hypertension (HTN) and chronic heart failure (CHF) on HRQoL in other minorities such as African Americans and Native Americans.
