Hubungan Pajanan Pm2.5 Terhadap Penyakit Paru Obstruktif Kronik (Ppok) Pada Pekerja Di Pintu Gerbang Pelabuhan Tanjung Priok Tahun 2018

Background. Workers at the Port of Tanjung Priok gate are at risk of exposure to PM2.5 generated from vehicles and capable of causing chronic obstructive pulmonary disease (COPD). This study aims to identify the relationship between PM2,5 with the incidence of COPD on workers at the Gate. Methods. The design of this study was cross sectional with a sample of 75 workers. PM2.5 measurements are done at 30 points at the gate. As for the identification of COPD events using spirometry and questionnaire tests. The variables in this study were PM2,5 concentration, age, nutritional status, disease history, exercise habit, heavy smoking, APD usage, length of work, length of service, distance and travel time. Results. The results showed no significant relationship between the concentration of PM 2.5 with the incidence of COPD value p = 0.149. As for other variables, only the use of PPE has a significant relationship with the incidence of COPD, p value = 0.001. Meanwhile, age (OR = 1.5) nutritional status (OR = 1.5) history of disease (OR = 1,7), exercise habits (OR = 2,3), duration of work (OR = 1,1), work (OR = 2,2), distance traveled (OR = 2,3) and travel time (OR = 1,9). Conclusions. The result of multivariate analysis shows that there is no confounding variable that can control the PM2,5 variable to the incidence of COPD. Need for further research with longitudinal approach to know big risk of PM2,5 to the incidence of COPD.
