OBJECTIVE
To determine whether there was an increased incidence of leukaemias and lymphomas in young people aged less than 25 years in the locality of a petrochemical plant at Baglan Bay, South Wales.
METHODS
Geographical population based study to compare the observed and expected incidence of leukaemia and lymphoma with onset before the age of 25, in the years 1974 to 1991. The population was aged 0-24 years and lived within 1.5 and 3 km of the plant. The observed number of cases in various categories were compared with the expected numbers of cases calculated from the Welsh cancer registration rates.
RESULTS
Although the observed numbers were generally greater than would be expected, none of the comparisons showed significant excess of leukaemias or lymphomas for any period of years.
CONCLUSIONS
The study shows that the incidence of leukaemias and lymphomas in children and young people in the area around the BP Chemical site at Baglan Bay, South Wales, between the years 1974 and 1991 was not significantly greater than normal.
目的
确定在南威尔士巴格兰湾一家石化厂所在地，年龄小于25岁的年轻人中白血病和淋巴瘤的发病率是否有所增加。
方法
基于地理人群的研究，比较1974年至1991年间25岁之前发病的白血病和淋巴瘤的观察发病率与预期发病率。研究人群年龄在0至24岁之间，居住在距工厂1.5公里和3公里范围内。将各类别的观察病例数与根据威尔士癌症登记率计算出的预期病例数进行比较。
结果
尽管观察到的病例数总体上高于预期，但在任何年份的比较中，白血病或淋巴瘤均未显示出显著的超额发病情况。
结论
该研究表明，1974年至1991年间，南威尔士巴格兰湾英国石油化工厂区周边儿童和年轻人中白血病和淋巴瘤的发病率并未显著高于正常水平。
