INTRODUCTION
informal sector carpenters in Douala, Cameroon, face potential risks to their respiratory health due to daily exposure to fine particles and wood dust. The study aims to demonstrate the importance of preventing respiratory problems in this population through regular use of filtering face pieces (FFP3) respiratory masks.
METHODS
the before-after study involved 37 carpenters who wore FFP3 masks during their professional activities for five months. Spirometry measurements were taken before and after the intervention to assess changes in respiratory function.
RESULTS
significant improvements were observed in forced vital capacity (FVC) 89.6 % to 95.0 % (p<0.000), forced expiratory volume in one second (FEV1) 88.1 % to 95.0 % (p<0.000), Tiffeneau index 82.4 to 84.9 (p<0.000), and peak expiratory flow (PEF) 6.7 l/s to 7.9 l/s (p<0.000) after mask usage, indicating enhanced lung function.
CONCLUSION
the regular use of FFP3 masks had a positive impact on the respiratory health of informal sector carpenters in Douala, enhancing lung function and reducing airway obstruction. The study highlights the importance of preventive measures to safeguard the respiratory well-being of workers exposed to occupational hazards. Spell out Greek characters (i.e: alpha, beta).
简介
喀麦隆杜阿拉的非正规部门木匠由于日常接触细颗粒物和木屑，其呼吸健康可能面临潜在风险。本研究旨在通过定期使用过滤式面罩（FFP3）证明预防该人群呼吸问题的重要性。
方法
这是一项前后对照研究，涉及 37 名木匠，他们在专业活动中佩戴 FFP3 口罩五个月。在干预前后进行肺量测定以评估呼吸功能的变化。
结果
使用口罩后，用力肺活量（FVC）从 89.6%增加到 95.0%（p<0.000），一秒用力呼气容积（FEV1）从 88.1%增加到 95.0%（p<0.000），Tiffeneau 指数从 82.4 增加到 84.9（p<0.000），呼气峰值流量（PEF）从 6.7 l/s 增加到 7.9 l/s（p<0.000），表明肺功能增强。
结论
定期使用 FFP3 口罩对杜阿拉非正规部门木匠的呼吸健康产生了积极影响，改善了肺功能并减少了气道阻塞。该研究强调了采取预防措施保护接触职业危害工人呼吸健康的重要性。请拼写出希腊字母（如：alpha、beta）。
