Smoking Among Chinese Livery Drivers.

We aimed to assess a key risk factor for lung cancer, smoking, in a vulnerable group, Chinese livery drivers in New York City (NYC). This is a nested cohort study conducted in the summer/fall of 2014 within a larger NIMHD-funded R24 program, the Taxi Network. The Taxi Network Needs Assessment (TNNA) survey was administered to a broad demographic of drivers.
