[ABSTRAK
Mengetahui proporsi gangguan fungsi paru pada remaja jalanan perokokdan hubungan antara perilaku merokok dengan gangguan fungsi paru.Metode: Studi potong lintang pada 317 anak jalanan, usia 10-18 tahun, terdiridari perokok dan bukan perokok. Uji fungsi paru dilakukan pada subjek denganmenilai FEV1/ FVC, FEV1, FVC, V50 dan V25.Hasil: Subjek perokok sebanyak 182 remaja jalanan (57,4%), sebagian besarmerupakan perokok kadang-kadang (53%), lama merokok 1-2 tahun (54%), jenisrokok yang digunakan adalah rokok filter (58%), dan jumlah rokok yangdikonsumsi 1-10 batang per hari (93%). Rerata parameter fungsi paru subjekperokok lebih rendah dibandingkan bukan perokok, dengan perbedaan bermaknapada nilai FEV1 dan FVC (p<0,05). Rerata nilai FEV1 dan FVC subjek perempuanperokok berbeda bermakna dengan bukan perokok, begitupun dengan rerata nilaiFVC subjek lelaki (p<0,05). Proporsi gangguan fungsi paru subjek perokokberbeda bermakna dengan bukan perokok (p=0,016). Terdapat hubungan antarajenis rokok dengan gangguan fungsi paru (p<0,001), dimana pengguna rokokkretek paling banyak mengalami gangguan. Terdapat hubungan antara derajatperilaku merokok dengan gangguan fungsi paru (p=0,046).Simpulan: Rerata parameter uji fungsi paru (FEV1 dan FVC) pada remaja jalananperokok lebih rendah dibandingkan bukan perokok. Proporsi gangguan fungsiparu pada remaja jalanan perokok 26,5%, terdiri dari campuran (16,1%), restriktif(8,2%) dan obstruktif (2,2%). Jenis rokok dan derajat perilaku merokok memilikihubungan dengan kejadian gangguan fungsi paru.

ABSTRACT
Street children and smoking prevalence are highly increasing.Studies on pulmonary function among adolescent street children smokers are stilllimited with controversial result.Objective: To determine proportion of pulmonary dysfunction among adolescentstreet children smokers and to evaluate relation between smoking behaviour withpulmonary dysfunction.Methods: A cross sectional study among 317 street children, aged 10-18 yearsold, including smokers and non-smokers which were recruited consecutively.Subjects undergone pulmonary function test which measured FEV1/ FVC, FEV1,FVC, V50 and V25.Results: Subject smokers were 182 children, most of them were occasionalsmokers (53%), smoking period around 1-2 years (54%), using filtered cigarettes(58%), and consuming 1-10 cigarettes per day (93%). Mean pulmonary functionparameter values of smokers were lower than non-smokers, significant differencefor FEV1 and FVC (p<0.05). Mean FEV1 and FVC between smoking and nonsmokinggirls were significant difference, and also mean FVC of boys (p<0.05).There was significant difference in proportion of pulmonary functionabnormalities between smokers and non-smokers (p=0.016). There was relationbetween types of cigarettes with pulmonary dysfunction (p<0.001), theabnormalities mostly impact to kretek smokers. There was relation betweensmoking behaviour with pulmonary function abnormalities (p=0.046).Conclusion: Mean pulmonary function parameter values (FEV1 and FVC) ofsmokers were lower than non-smokers. Pulmonary dysfunction proportion amongadolescent street children smokers was 26.5%, consist of combined disorder(16.1%), restrictive (8.2%) and obstructive (2.2%). There was relation betweentypes of cigarettes and smoking behavior with pulmonary function abnormalities.;Street children and smoking prevalence are highly increasing.Studies on pulmonary function among adolescent street children smokers are stilllimited with controversial result.Objective: To determine proportion of pulmonary dysfunction among adolescentstreet children smokers and to evaluate relation between smoking behaviour withpulmonary dysfunction.Methods: A cross sectional study among 317 street children, aged 10-18 yearsold, including smokers and non-smokers which were recruited consecutively.Subjects undergone pulmonary function test which measured FEV1/ FVC, FEV1,FVC, V50 and V25.Results: Subject smokers were 182 children, most of them were occasionalsmokers (53%), smoking period around 1-2 years (54%), using filtered cigarettes(58%), and consuming 1-10 cigarettes per day (93%).
