Genome-wide interaction study of physical activity and genetic susceptibility on colorectal cancer using UK biobank data.

ABSTRACT: Colorectal cancer (CRC) risk is influenced by a complex interplay between genetic predisposition and lifestyle factors, such as physical activity (PA). We aimed to conduct a genome-wide interaction study (GWIS) to explore single nucleotide polymorphisms (SNPs), and genes modulated by PA on CRC risk using data from the UK Biobank. Among 272,270 eligible participants, 2,979 CRC cases were matched with 11,435 controls using a incidence density matching approach to avoid potential biases that may arise when using excessively large unmatched control groups, and to preserve comparability in the timing and distribution of exposure. PA was defined as whether individuals met the international criteria. We used conditional logistic regression models to assess the significance for the SNP x PA intera
