The overlap of smoking and obesity among adults in the United States is low, but nine million are people affected, and this subgroup is concentrated among lower socioeconomic groups. Healton and colleagues (p 25) analysed data of > 29 000 adults from the 2002 national health interview survey. They found that 23.5% of adults were obese, 22.7% smoked, and 4.7% smoked and were obese. Statistics on the overlap of these two conditions could help inform clinical intervention, say the authors.
