    Article - En anglais

    Background

    Rates of oesophageal/gastric cardia cancer in Linxian, a rural county in north central China, are among the world's highest, but the risk factors are not well understood.

    Methods

    A nested case-control study of oesophageal and stomach cancers was conducted within a cohort of 29 584 adults who participated in a randomized nutrition intervention trial.

    Information on participant characteristics collected during interviews before the trial began was compared between individuals who subsequently developed cancers of the oesophagus (N=640) or stomach (N=539), mainly cardia, and individually matched controls (control/case ratio=5).

    Analyses were performed separately for oesophageal and stomach cancers using conditional logistic regression.
