Wood dusts are known to cause respiratory disorders like rhinitis and asthma. This study was therefore done to determine the magnitude of the problem among woodworkers in south-eastern Nigeria exposed to high level of wood dust. Five hundred and ninety one woodworkers were selected using a stratified random sampling. The prevalence of woodwork-related rhinitis and asthma were then observed in the study population. Also the peak expiratory flow rate (PEFR) of each woodworker was obtained. The prevalence of occupational rhinitis was 78%, while that of asthma was 6.5%. As period of woodwork increased the prevalence of rhinitis and asthma increased (rhinitis: chi2 trend = 53.015, df = 1, P = 0.000). For asthma, chi2 trend = 19.721, df = 1, P = 0.000). Also the PEFR significantly became low with increasing years of exposure to woodwork (chi2 trend = 75.965, df = 1, P = 0.000). In conclusion the prevalence of rhinitis and asthma in woodworkers was high and significantly increased with years of working as a woodworker.
已知木尘会引发鼻炎和哮喘等呼吸道疾病。因此，开展这项研究以确定在尼日利亚东南部接触高浓度木尘的木工中该问题的严重程度。采用分层随机抽样选取了591名木工。随后在研究人群中观察与木工工作相关的鼻炎和哮喘的患病率。还获取了每位木工的呼气峰值流速（PEFR）。职业性鼻炎的患病率为78%，而哮喘的患病率为6.5%。随着木工工作时长增加，鼻炎和哮喘的患病率上升（鼻炎：卡方趋势 = 53.015，自由度 = 1，P = 0.000）。对于哮喘，卡方趋势 = 19.721，自由度 = 1，P = 0.000）。而且，随着接触木工工作年限的增加，PEFR显著降低（卡方趋势 = 75.965，自由度 = 1，P = 0.000）。总之，木工中鼻炎和哮喘的患病率很高，并且随着木工工作年限的增加而显著上升。
