摘要：To observe whether there is a relationship between smoking habits and socioeconomic factors among Japanese people, we analyzed data from a large population survey with a random sampling method throughout the country. Information of smoking habits (never, current, and former smoking), occupation, length of education, and annual household income was obtained from 1, 454 participants. Prevalence of smokers and socioeconomic status was inversely associated in Japan as well as in other developed countries. However, the association was not so strong as that in other countries.
