Medium-density fibreboard (MDF) is a wood composite material, composed primarily of softwood, bonded with a synthetic formaldehyde-based resin. It is increasingly used, as it has various advantages over natural woods.
Enquiry of the national reporting scheme data and three case reports were used to further the evidence base linking this exposure to occupational asthma (OA).
From 1991 to 2007, 21 cases of occupational sensitization to MDF were reported to the UK voluntary reporting scheme, Surveillance of Work Related Occupational Respiratory Disease (SWORD): 18 reported as occupational asthma (OA) and 3 as occupational rhinitis. All workers were male, with a mean age of 48 years, working in education, furniture manufacturing or joinery among other employments.
Whilst reporting scheme data identified relatively small numbers of cases of OA likely to be due to MDF, the evidence base supporting this link is generally lacking. The three cases presented, where OA was attributed to MDF exposure, add to this evidence.
中密度纤维板（MDF）是一种木质复合材料，主要由软木制成，用合成的基于甲醛的树脂粘合而成。它的使用越来越广泛，因为它具有许多优于天然木材的优点。
查询国家报告计划数据和三例病例报告，以进一步为将这种接触与职业性哮喘（OA）联系起来提供证据基础。
1991 年至 2007 年期间，有 21 例对 MDF 职业致敏的病例向英国自愿报告计划，职业相关呼吸道疾病监测（SWORD）报告：18 例报告为职业性哮喘（OA），3 例报告为职业性鼻炎。所有工人均为男性，平均年龄为 48 岁，从事教育、家具制造或细木工等工作。
虽然报告计划数据确定了由于 MDF 而导致的相对较少的职业性哮喘病例，可能是由于 MDF 引起的，但支持这种联系的证据基础通常是缺乏的。提出的三个病例中，OA 归因于 MDF 暴露，增加了这方面的证据。
