The Claim

Obesity is associated with a 36% increased risk of colorectal cancer in adults, as indicated by a pooled hazard ratio of 1.36 (95% CI: 1.24–1.48) from a meta-analysis of 66 observational studies involving over 83 million participants.

In plain English

Adults with obesity have a higher likelihood of developing colorectal cancer compared to those without obesity, based on data from millions of people across multiple studies.

See the scientific wording

Obesity is associated with a 36% increased risk of colorectal cancer in adults, based on a meta-analysis of 66 observational studies involving over 83 million participants, with a pooled hazard ratio of 1.36 (95% CI: 1.24–1.48), indicating that higher body mass index correlates with greater incidence of colorectal cancer across diverse populations.

What the research says

1 study
  1. Study: Overweight and obesity significantly increase colorectal cancer risk: a meta-analysis of 66 studies revealing a 25–57% elevation in risk

    This study found that people who are overweight or obese have a 36% higher chance of getting colon or rectal cancer compared to people at a healthy weight, based on data from millions of people. So yes, being overweight is linked to a higher risk of this type of cancer.
