Early Life Weight Linked to Higher Bowel Cancer Risk in Adults
Research suggests that being overweight at a young age significantly increases the risk of developing bowel cancer in adulthood. Experts in the Netherlands analyzed 37 studies on body weight in early life and found a strong correlation between a higher body mass index (BMI) in children, teenagers, and young adults, and an increased risk of colorectal cancer. The study also revealed that higher birth weights in babies are associated with a higher risk of getting bowel cancer later in life.
Key Takeaways:
- A higher body mass index (BMI) in children, teenagers, and young adults is associated with a 5-18% increased risk of developing bowel cancer in adulthood.
- A 1kg increase in birth weight is linked to a 9% heightened risk of bowel cancer later in life.
- An increase in BMI of 5kg/m2 in people aged 18-25 heightened the risk of developing bowel cancer in adulthood by 12%.
- The study found that a higher BMI in children aged 2-9 is linked to a higher risk of cancer in the colon.
- Bowel cancer is the UK's fourth most common cancer, with almost 44,000 diagnoses a year.
- Dr. Dieuwertje Kok and her team at Wageningen University & Research highlighted the importance of understanding the relationship between early life factors and colorectal cancer risk in adults.
Statistics:
- 44,000 - the number of bowel cancer diagnoses in the UK each year.
- 18.5-24.9 - the healthy range for body mass index (BMI) in adults, according to the NHS.
- 5-18% - the increased risk of developing bowel cancer in adulthood associated with a higher BMI in youngsters aged 10-19.
- 9% - the heightened risk of bowel cancer later in life associated with a 1kg increase in birth weight.
- 12% - the increased risk of developing bowel cancer in adulthood associated with an increase in BMI of 5kg/m2 in people aged 18-25.
