abstract = {The association between excess weight and colorectal cancer
(CRC) risk may have been underestimated due to potential
weight loss during pre-clinical sojourn time of CRC. We
aimed to investigate this association and the corresponding
population attributable fraction (PAF), accounting for
prediagnostic weight loss.Data from the UK Biobank
prospective cohort were used. Multivariable adjusted hazard
ratios (HR) and their $95\%$ confidence intervals (CI) for
various periods of follow-up and the corresponding PAF of
excess weight were calculated.During a median of 10.0 years
of follow-up, of 453,049 participants, 4794 developed CRC.
The excess weight-CRC association became substantially
stronger with including increasing lengths of follow-up in
the analyses and further excluding the initial years of
follow-up. HRs $(95\%$ CIs) for overweight and obesity were
1.06 (0.97-1.16) and 1.14 (1.03-1.26) after 7 years of
follow-up, 1.13 (1.05-1.21) and 1.23 (1.14-1.33) when
including complete follow-up length, and 1.26 (1.12-1.43)
and 1.42 (1.24-1.63) when excluding the initial 7 years of
follow-up. The corresponding PAFs of excess weight were
estimated as $6.8\%,$ $11.3\%,$ and $19.0\%,$
respectively.Comprehensive consideration of the potential
effect of prediagnostic weight loss discloses a much
stronger impact of excess body weight on CRC risk than
previously assumed.},
