Welding fumes exposure, body mass index and duration of smoking decrease physical fi tness among welders

AbstrakLatar belakang: Pajanan asap pengelasan dapat mengganggu kesehatan, antara lain penurunan kebugaran jasmani. Penelitian ini bertujuan menganalisis efek pajanan asap pengelasan terhadap kebugaran jasmani pengelas.Metode: Penelitian menggunakan desain potong lintang dan subjek penelitian dipilih secara purposif di antara pengelas di suatu pabrik knalpot di sekitar Jakarta tahun 2012. Beberapa karakteristik demografi , riwayat pekerjaan, dan kebiasaan subjek diperloleh dengan wawancara. Kebugaran jasmani diperiksa dengan metode Queen’s College Step Test. Total pajanan asap dinilai menggunakan metode semi kuantitatif yaitu perkalian pajanan asap dengan masa kerja sebagai pengelas.Hasil: Subjek penelitian berjumlah 110 orang, yang berusia antara 19-55 tahun, dengan masa kerja 1-16 tahun. Pajanan asap diperusahaan sebesar 15 mg/m3 menurut data pemeriksaan rutin perusahaan tahun 2012. Umur dan aktivitas fi sik tidak berkorelasi terhadap tingkat kebugaran jasmani pengelas. Akan tetapi didapatkan korelasi negatif antara total pajanan asap, index massa tubuh (IMT), dan kebiasaan lama merokok terhadap tingkat kebugaran jasmani pengelas. Korelasi terhadap tingkat kebugaran jasmani pengelas tersebut adalah: total pajanan asap [koefi sien regresi (r) = -0,07; 95% koefi sien interval (CI) = -0,10; -0,04]; IMT (r =-0,38; 95% CI = -0,64;-0,09); dan kebiasaan lama merokok (r = -0,16; 95% CI = -0,28;-0,04)Kesimpulan: Peningkatan pajanan asap pengelasan, index massa tubuh, dan lama merokok menurunkan tingkat kebugaran jasmani pengelas.

This study aimed to analyze the effect of welding fumes exposure with the level of welder’sphysical fi tness.Methods: This cross-sectional using purposive selected by sampling selection method among welders in the muffl er factory at outskirt of Jakarta in 2012. Several characteristic demography, occupational history,and habits were obtained through interview. Welding fumes exposure obtained by semi quantitative method. Physical fi tness was obtained by physical examination using Queen’s College Step Test.Results: The total of subjects in this study were 110 people, 19-55 years of age, total duration of work between 1-16 years. We found that there were no signifi cant association between the age and physical activity of respondents with the level of welder physical fi tness. We noted negative correlation between the total fume exposure, body mass index, duration of smoking habits and the level of welder physical fi tness. The correlation were: the total fume exposure [regression coeffi cient (r)= -0,07; 95% confi dence interval (CI)= -0,10;-0,04]; body mass index (r= -0,38; 95% CI= -0,64;-0,09); and duration of smoking habits (r= -0,16; 95% CI= -0,28;-0,04).Conclusion: Increase in total welding fumes exposure, body mass index, and duration of smoking habit will be decrease welder physical fi tness.
