The prevalence of smoking in Indonesia is worrying. In fact, smoking increases the risk of cancer, cardiovascular and respiratory disorders. The content of cigarette smoke that are toxic carcinogenic is irritating to the respiratory mucosal epithelium and affect the smooth muscle of the airway wall. The purpose of this study was to determine the relationship of active and passive smoking behavior with the incidence of lung function abnormality (FEV 1 <80%). Observational analytic cross-sectional study is conducted in Bantul Yogyakarta with 84 volunteers who arc willing to sign the sheet capability. The function of lung is observed with the FEV1 parameters set by the spirometer. Structured interviews are guided by a questionnaire carried out by trained personnel to explore the active and/or passive smoking habits of respondents, presence or absence of obstructive pulmonary lisease, type of work and education history. Respondents who are willing to participate in the study but have shown a history of obstructive lung disease are excluded as volunteers. The data are presented descriptively followed by bi variant analysis. Clii squar test is used to determine the relationship of passive or active smoking habits and pulmonary physiological functions (normal FEV1 (80% or more) or normal (<80%)) with a confidence level of 95%. The results show that 44% of respondents are male and 56% female with 70% aged 50 years or more. Most respondents (58%) are high school educated or academic. The occupations of the respondents are mostly in private Sector, laborers, farmers or unemployed (87%), only 13% is in public service or military service. As many as 33% respondents are passive smokers as well as active smokers. The majority (64%) of respondents has normal lung function (FEVI> 80%), 36% has abnormal lung function. From the chi square test between passive or active smoking habits with lung function, it is known that passive smoking and active smoking habits has an association with the incidence of lung function abnormality (FEV 1 <80%). Incidence of lung function abnormalities lOx in active smokers is than non-smokers active (OR = 10; CI: 1.9 - 17; p <0.05). Incidence of lung function abnormalities 7x in smokers than non-passive passive smoking (0R 7.8 CI: 1.5- 13; p <0.05).
