Association between Childhood Leukaemia and Exposure to Power-frequency Magnetic Fields in Middle Europe

摘要: Abstract Objective Higher levels of exposure to extremely low-frequency magnetic fields (ELF-MF) are associated with a slightly increased risk childhood leukaemia. Compared more-developed Western countries, higher evident in the Czech Republic, probably because different types housing. In light this, we aimed examine association between ELF-MF and leukaemia Republic. Methods We conducted paired case-control study. The cases (children leukaemia) were age- sex- permanent residence-matched controls without leukaemia). Although this limited potential bias confounding, it also our number participants. Results matched analyses included 79 pairs. No significant was observed for exposures over 0.2 μT (odds ratio [OR]=0.93, confidence interval [CI]=0.45-1.93), 0.3 (OR=0.77, CI=0.34–1.75), or 0.4 (OR=0.9, CI=0.37–2.22). Conclusion Despite Middle Eastern Europe, no indication an determined. This contrast findings previous studies countries.
