@entity13414 @entity146
INTRODUCTION: Many studies have clearly linked exposure to @entity13414 ( @entity13414 ) to various somatic diseases, however, few studies have examined the relationship between @entity13414 and @entity146 and those that have were only conducted with specific groups. The purpose of this study was to examine the association between @entity13414 exposure and @entity146 among Chinese residents in both worksites and public places. METHODS: A cross-sectional multistage sampling design was used to interview subjects from 21 selected cities in China. Using a standardized questionnaire including demographic characteristics, @entity13414 exposure, and mental health information was collected. Multiple logistic regression analysis was used to assess the association between @entity13414 exposure and @entity146 . RESULTS: Sixteen-thousand-eight-hundred-sixty-six valid questionnaires were collected and utilized in this study. Of 11,206 non-smokers, @entity13414 exposure prevalence in workplaces and public places were respectively 78.4  % (95  % C.I.:74.3-82.5  %) and 80.7  % (95  % C.I.:74.6-86.5  %). Multiple logistic regressions showed @entity13414 exposures in these venues were positively related to @entity146 . CONCLUSIONS: These findings further support the health hazards of @entity13414 exposure. Findings underscore the importance of controlling @entity13414 exposure, and can be used to inform future @entity13414 control policies and reinforce the need for public education in China.
