A total of 2528 workers in flax mills in Northern Ireland were followed up for 16 years. Follow-up was 97% complete. Deaths were identified and date and cause ascertained. Expected deaths were calculated on the basis of age and sex specific rates for Northern Ireland. Both male and female workers had fewer deaths than expected, and mortality showed no clear relationship with type of work. There was a small excess in the mortality of the workers who had had byssinosis at the time of the original survey, but there was no evidence that the more severe grades of byssinosis were associated with higher mortality than the less severe grades. Workers who smoke are known to have an increased risk of developing byssinosis, and cigarette smoking may be responsible for most of the excess deaths in the workers with byssinosis.
对北爱尔兰亚麻厂的2528名工人进行了为期16年的随访。随访完成率为97%。确定了死亡情况，并查明了死亡日期和原因。根据北爱尔兰的年龄和性别特异性死亡率计算预期死亡人数。男性和女性工人的死亡人数均低于预期，且死亡率与工作类型无明显关系。在最初调查时有棉尘肺的工人死亡率略有偏高，但没有证据表明较严重等级的棉尘肺比较轻等级的棉尘肺与更高的死亡率相关。已知吸烟的工人患棉尘肺的风险增加，吸烟可能是导致患棉尘肺工人额外死亡的主要原因。
