Περίληψη:
The associations of body mass index (BMI) and other anthropometric
measurements with lung cancer were examined in 348,108 participants in
the European Investigation Into Cancer and Nutrition (EPIC) between 1992
and 2010. The study population included 2,400 case patients with
incident lung cancer, and the average length of follow-up was 11 years.
Hazard ratios were calculated using Cox proportional hazard models in
which we modeled smoking variables with cubic splines. Overall, there
was a significant inverse association between BMI (weight (kg)/height
(m)(2)) and the risk of lung cancer after adjustment for smoking and
other confounders (for BMI of 30.0-34.9 versus 18.5-25.0, hazard ratio =
0.72, 95% confidence interval: 0.62, 0.84). The strength of the
association declined with increasing follow-up time. Conversely, after
adjustment for BMI, waist circumference and waist-to-height ratio were
significantly positively associated with lung cancer risk (for the
highest category of waist circumference vs. the lowest, hazard ratio =
1.25, 95% confidence interval: 1.05, 1.50). Given the decline of the
inverse association between BMI and lung cancer over time, the
association is likely at least partly due to weight loss resulting from
preclinical lung cancer that was present at baseline. Residual
confounding by smoking could also have influenced our findings.
