Quality-of-life scores range from 0 to 1, with 0 representing the worst health imaginable and 1 the best. Scores were predicted on the basis of a regression of scores on the European Quality of Life–5 Dimensions (EQ-5D) visual-analogue scale available in the Medical Expenditure Panel Survey, 2003.

BMI denotes body-mass index.

The quality of life for obese and morbidly obese smokers was estimated jointly for all respondents who were 65 years of age or older, since the number of respondents in these groups was small.
