Using data from the Swedish Cancer-Environment Register, time trends in the standardized incidence ratio (SIR) for lung cancer 1961-1979 were studied in different occupations. After adjustments for differences in the SIR with respect to year of birth, only the decreasing trends for blacksmiths and members of the armed forces as well as increasing trends for foundry workers and construction machine operators were significant (p less than 0.05). For bakers and pastry cooks, there was a significant interaction between year of birth and observation period in relation to SIR. Data on smoking habits, obtained from a sample of the population, did not seem to explain the trends.
利用瑞典癌症-环境登记处的数据，研究了1961年至1979年不同职业肺癌标准化发病比（SIR）的时间趋势。在对SIR因出生年份不同而产生的差异进行调整后，只有铁匠和武装部队人员的下降趋势以及铸造工人和建筑机械操作员的上升趋势具有显著性（p<0.05）。对于面包师和糕点厨师，出生年份与观察期之间在SIR方面存在显著的交互作用。从一部分人口样本中获得的吸烟习惯数据似乎无法解释这些趋势。
