The Ministry of Health, Labour and Welfare (MHLW) of Japan conducted a nationwide survey on environmental factors of parenting in 2001-2. A self-administered questionnaire was sent to 53,575 households with a six-month infant. The number of subjects corresponded to 5% of all 1.18 million babies born in 2001. Regarding smoking behavior of parents, response rate was 83.2%. Current smoking status of parents; both mother and father smoke 15.9%, only father smokes 47.6%, only mother smokes 1.2%, neither parent smokes 35.2%. The following valuables were adjusted one another, and reported relationships were statistically significant. For mothers, factors, such as younger age, husband's smoking, low household income, were positively related to smoking behavior. On the other hand, older age, living rural area, current breastfeeding and high household income were negatively associated with current maternal smoking. For fathers, factors associated with their smoking status were almost identical to those for mothers. The relationship, however, was stronger in mothers than in fathers, possibly reflecting the difference of smoking rate between males and females in Japan. Approximately 65% of households with a six-month baby had at least one smoking parent. The results showed low socio-economic status, spouse's smoking and bottle-feeding were positively associated with parents' smoking, that is, infant's passive smoking.
