AB  - Objectives To examine the association between socioeconomic status (SES) and health-related quality of life (HRQOL) in a sample of elderly Chinese people in Hong Kong. Study Design Cross-sectional study. Setting 18 elderly health centers in Hong Kong. Participants This study was based on a cohort aged 65 years or above who were enrolled in the Elderly Health Services from 1998 to 2005 in Hong Kong. Initially, 3324 individuals were randomly sampled from the baseline database. In the end, 2441 successful cases were obtained for the telephone survey. After excluding cases with missing SES or HRQOL information and the cases whose questionnaires were answered by their family members, 2347 individuals were included in the final analysis. Results Elderly Chinese with less subjective economic hardship reported much better self-rated health (SRH) (OR 1.57–4.70, all p<0.01)< and higher Medical Outcomes Study short form (SF)12 scores (β 2.56–10.26, all p<0.01) than those with economic hardship. Male individuals in the highest education and occupation subgroup reported better HRQOL comparing with the baseline subgroup (OR for SRH 1.91–3.26, p<0.01; β 2.63–4.96, p<0.05). Two economic indicators, income and expenditure, only showed significant positive associations with physical SF12 scores for men (β 2.91–5.42, all p<0.05). Housing tenure was associated with SRH (OR 1.34 for men and 1.27 for women, p<0.05) but not SF12 scores. Conclusions Economic hardship showed the strongest association with HRQOL among all SES indicators. Educational level, occupational level and economic indicators tended to associate with physical HRQOL only among elderly Chinese men. More attention should be placed on subjective SES indicators when investigating influences on HRQOL among elderly Chinese people.
