title: Health insurance coverage and health-related quality of life: analysis of 2000 Medical Expenditure Panel Survey data.
abstract: This study investigated relationships between health insurance status and health-related quality of life (HRQOL) using the 2000 Medical Expenditure Panel Survey data. Health-related quality of life was measured using the SF-12 Physical Component Summary (PCS) and SF-12 Mental Component Summary (MCS). The analysis controlled for sociodemographic and attitudinal variables and medical conditions. The analysis also investigated and controlled for possible reverse causality between HRQOL and health insurance in the models. After adjusting for covariates, individuals without health insurance had significantly lower mean PCS scores (beta=-5.8; SE=0.4) than those with health insurance. The adjusted association between no health insurance and MCS scores (beta=-1.1; SE=0.4) also was significant. The adjusted difference in HRQOL among people with health insurance and those without it exceeds or is comparable to adjusted differences in HRQOL between people with each of various medical conditions and people without them.
