Abstract 16035: Socioeconomic Status and 1-year Mortality Among Patients With Heart Failure in China: Findings From the China-PEACE Prospective Heart Failure Study

Abstract

Introduction: Socioeconomic status (SES) has been shown to affect the survival of patients with heart failure (HF) in the developed countries. However, the association between SES with mortality has been scarcely investigated in China. Methods: We studied a national sample of 4717 patients admitted to 52 hospitals for HF who had SES record and were discharged alive from the China PEACE-Prospective Heart Failure Study. SES were obtained through questionnaires during hospitalization, and were measured by self-reported employment status (employed, retired, never work), education level (low educational attainment defined as primary school or below; intermediate educational attainment defined as junior high school; high educational attainment defined as senior high school or above) and partner status (having a partner, no partner). We assessed the association between SES and 1-year all-cause mortality using Cox models. Results: The median age of study population was 67 (57,76) years, 37.6% were women.17.6% of patients had a job, 72.5% retired and 9.9% never worked. The proportions of patients who had low, intermediate and high educational attainment were 43.0%, 29.0% and 28.0%,respectively. Additionally, 80.8% of patients had a partner. In unadjusted analysis, compared with patients who had a job, who had high educational attainment and who had a partner, respectively, currently no work status (retired group: HR 2.08, 95%CI 1.64 to 2.63; never work group: HR 2.23, 95%CI 1.78 to 3.22), low educational attainment (HR 1.52, 95%CI 1.28 to 1.81) and no partner (HR 1.31, 95%CI 1.12 to 1.54) were all associated to higher mortality. After adjusting for patient characteristics, medication use at discharge and mutually adjusting for socioeconomic status, education level and partner status were not associated with mortality, However, patients without work currently (retired group: adjusted HR 1.52, 95%CI 1.17 to 1.97; never work group: adjusted HR 1.60, 95%CI 1.15 to 2.22) were still more likely to die within 1 year. Conclusions: In a national Chinese cohort of patients hospitalized for HF, currently no work status was associated with higher 1-year mortality risk, while the education level and partner status were not correlated with mortality.
