Welding fumes exposure decreases forced vital capacity but not height among welders

<p><strong><em>Abstrak</em></strong></p><p><em><strong>Latar belakang</strong>: Asap pengelasan antara lain dapat menyebabkan penurunan kapasitas vital paksa (KVP). Tujuan penelitian ini adalah untuk mengidentifi kasi beberapa faktor yang dapat berhubungan dengan KVP</em> <em>pada pengelas.</em></p><p><em><strong>Metode</strong>: Studi ini menggunakan desain potong lintang pada subjek pengelas di pabrik mobil sekitar Jakarta tahun 2012. Responden dipilih secara purposif. Pemeriksaan KVP menggunakan spirometri. Data pajanan</em> <em>asap didapatkan dari data yang dimiliki perusahaan. Data demografi , kebiasaan, dan pekerjaan diperoleh dengan wawancara.</em></p><p><em><strong>Hasil</strong>: Jumlah responden 124 dari 150, rentang umur 19-55 tahun dan telah bekerja antara 1-16 tahun. Data pajanan asap pada area pengelasan adalah 15 mg/m3, Pajanan asap pengelasan cenderung menurunkan kapasitas vital paksa [koefi sient regresi (r) = -0,004, 95% interval kepercayaan (CI) = -0,01;-0,00] dan makin tinggi tinggi badan cenderung KVP meningkat (r= 0,35; 95% CI = 0,02;0,05).</em></p><p><em><strong>Kesimpulan</strong>: Pajanan asap pengelasan cenderung menurunkan KVP, sebaliknya semakin tinggi tinggi badan cenderung meningkatkan KVP.

The study aimed to identify several factors related to FVC.</p><p><strong>Methods</strong>: The subject of this cross-sectional study consisted of welders in an automobile manufacture outskirt of Jakarta in 2012. We used purposive sampling selection. The assessments of FVC were using spirometri. Exposure fumes value of the workplace based on the assessements of the factory. Demographic and employment data was selected from interview.</p><p><strong>Results</strong>: A number 124 out of 150 welders which aged between 19-55 years who’s had 1-16 years worked. Exposure fumes value was 15 mg/m3 in the factory. The welding fume exposure decreased FVC [regression<br />coeffi cient (r) = -0.004; 95% confi dence interval (CI) = -0.01;-0.00]. On the other site, those who had more taller height had higher FVC (r = 0.035; 95% CI = 0.02;0.05).</p><p><strong>Conclusions</strong>: Welding fumes exposure was decreasing the FVC, but those who had more taller height had higher FVC among welders.
