“…In that large registry-based case–control study of 744 cases and 30 947 registry-based controls and 70 800 Cumbrian births database controls, occupation was taken from the child's birth certificate and likely exposure to ELF was identified from the job title. Similarly, Smulevich et al (1999) reported an excess risk for ALL in the offspring of mothers (OR=5.2; 95% CI=1.6–16.8) and fathers (OR=4.6; 95% CI=1.8–11.9) occupationally exposed to ELF at any time before the conception of the child. Exposure was determined by job title and information provided by the parents was related to a job exposure matrix by an occupational hygienist.…”

Background:Earlier studies have reported moderate increases in the risk of acute lymphoblastic leukaemia (ALL) among children whose mothers have been occupationally exposed to extremely low frequency (ELF) electromagnetic fields. Other studies examining parental occupational exposure to ELF and ALL have reported mixed results.Methods:In an Australian case–control study of ALL in children aged <15 years, parents were asked about tasks they undertook in each job. Exposure variables were created for any occupational exposure before the birth of the child, in jobs 2 years before birth, in jobs 1 year before birth and up to 1 year after birth.Results:In all, 379 case and 854 control mothers and 328 case and 748 control fathers completed an occupational history. Exposure to ELF in all time periods was similar in case and control mothers. There was no difference in exposure between case and control fathers. There was no association between maternal (odds ratio (OR)=0.96; 95% CI=0.74–1.25) or paternal (OR=0.78; 95% CI=0.56–1.09) exposure to ELF any time before the birth and risk of childhood ALL.Conclusion:We did not find an increased risk of ALL in offspring of parents with occupational exposure to ELF.

“…These early studies assessed exposure using job title as a proxy and the broad category that included petrol station attendants was associated with an increased risk of leukaemia in the offspring in two studies, 32,33 while five others found no association 31,34–37 . Later studies reported an increased risk of childhood leukaemia or ALL with paternal occupational exposure to related exposures: benzene, 38 hydrocarbons 39 or oil products 40,41 . The most recent report from the large United Kingdom Childhood Cancer Study found an increased risk of ALL with driving, and exposure to exhaust fumes and inhaled particulate hydrocarbons 42 …”

It is plausible that exposure of the parents before birth or of the child to sources of benzene increases the risk of childhood acute lymphoblastic leukaemia (ALL). The aim of this analysis was to investigate whether refuelling a vehicle with petrol before birth or burning wood to heat the home before or after the child's birth increased the risk of childhood ALL. Data from 389 cases and 876 frequency-matched controls were analysed using unconditional logistic regression, adjusting for study matching factors and potential confounders. The odds ratio (OR) for the mother ever refuelling a vehicle with petrol for non-occupational purposes before or during the pregnancy was 0.97 [95% confidence interval (CI) 0.69, 1.38]. The OR for the father for this exposure in the year before conception was 0.88 [95% CI 0.52, 1.48]. The OR for use of a closed wood burner to heat the home in the year before or during pregnancy was 1.41 [95% CI 1.02, 1.94] and 1.25 [95% CI 0.92, 1.70] after birth. We found no evidence that non-occupational refuelling a vehicle with petrol in the year before or during pregnancy increased the risk of ALL in the offspring. There was weak evidence that burning wood in a closed burner to heat the home increased the risk, but there was no dose-response relationship and chance could explain the finding.
