cancer,1 but the explanation for this association is
unclear. Whereas adult height is a marker of nutrition and health
throughout childhood, most growth before puberty is due to increases in
leg length. Leg length can therefore be used as a marker for exposures
that generate the association between adult height and

As childhood height is affected by the timing of puberty we
restricted our analysis to study members who were aged 2-8 years when
their height and leg length were measured. In all, 1167 of these 1392 subjects (84%) were traced and had information on childhood and adult
socioeconomic status, and they form the basis of this analysis. Using
Cox's proportional hazards models we examined mortality from cancer
between 1948 and 1997 in relation to internally derived z scores for
