  1. Case-control study of childhood leukaemia and cancer in Scotland : findings for neonatal intramuscular vitamin K.

    Article - En anglais

    Objective 

    To test the hypothesis of an association between neonatal intramuscular vitamin K and childhood leukaemia and other cancers.

    Design 

    Population based case-control study with data ed from hospital records.

    Setting 

    Scotland.

    Subjects 

    Children aged 0-14 years resident in Scotland from 1991-4 and diagnosed with leukaemia (150), lymphomas (46), central nervous system tumours (79), a range of other solid tumours (142), and a subset of acute lymphoblastic leukaemia (129).

    Controls were 777 children matched for age and sex, providing 417 matched sets (360 triplets and 57 pairs) for analysis.

    Main outcome measure 

    Odds ratios for the risk of childhood leukaemia and cancer and intramuscular vitamin K versus a combined group of oral doses, none, and no record.

    Results are given for information recorded in medical notes and data supplemented by hospital policy.

    Results 

    Odds ratios based on medical record ions showed no significant positive association for leukaemias (odds ratio 1.30 ; 95% confidence interval 0.83 to 2.03), acute lymphoblastic leukaemia (1.21 ; 0.74 to 1.97), lymphomas (1.06 ; 0.46 to 2.42), central nervous system tumours (0.74 ; 0.40 to 1.34), and other solid tumours (0.59 ; 0.37 to 0.96).

    There was no association with acute lymphoblastic leukaemia in children aged 1 to 6 years.

    Imputation of exposure from hospital policy gave similar results. (...)
