The present study was undertaken to examine the effects of the enforcement of a smoke-free school policy on HRQOL among healthy non-smoking schoolteachers with respect to their exposure to passive smoke. Methods Two self-reported questionnaire surveys were conducted the first before and the second after the enforcement of a total smoke-free public school policy in Nara City. A total of 1534 teachers were invited from 62 schools and their HRQOL was assessed using six domains extracted from the Medical Outcomes Survey Short Form-8 questionnaire SF-8 general health perception GH role functioning-physical RP vitality VT social functioning SF mental health MH and role functioning-emotional RE . The participants were divided into two groups according to their exposure to environmental tobacco smoke ETS at baseline participants not exposed to ETS at school nonsmokers and participants exposed to ETS at school passive smokers . Changes in each SF-8 score were evaluated using paired t-tests for each group and their inter-group differences were evaluated using multiple linear regression analyses adjusted for sex age school type managerial position and attitude towards a smoke-free policy. Results After ineligible subjects were excluded 689 teachers were included in the analyses. The number of nonsmokers and passive smokers was 447 and 242 respectively.
