A study has been made of the relationship between socio-economic factors and the incidence of acute lymphoblastic leukaemia (ALL) of childhood. It was found that the incidence of childhood ALL in 12 areas of Queensland. Australia, correlated well with some indicators of above-average socio-economic status for these areas. A similar result was found when Brisbane City was studied separately. Social class was determined from the fathers' occupations at the time of diagnosis. There was found to be a higher than expected number of ALL cases in each of the upper 5 social classes and a lower than expected number in the remaining 2 lower classes. Factors associated with differences in lifestyle amongst the various social classes may increase or decrease the risk of development of ALL.
一项关于社会经济因素与儿童急性淋巴细胞白血病(ALL)发病率之间关系的研究已经展开。研究发现,澳大利亚昆士兰州12个地区的儿童ALL发病率与这些地区高于平均水平的社会经济状况的一些指标密切相关。单独研究布里斯班市时也发现了类似的结果。社会阶层是根据诊断时父亲的职业来确定的。结果发现,在社会阶层排名前5的每一类中,ALL病例数都高于预期,而在其余2个较低阶层中则低于预期。不同社会阶层之间生活方式差异相关的因素可能会增加或降低患ALL的风险。
