Glasgow Study Links Prolonged Sitting to Increased Cancer Risk and Mortality

Insights from the University of Glasgow Research

According to НВ — Техно: On September 8, researchers at the University of Glasgow published findings revealing a strong connection between extended periods of uninterrupted sitting and a higher likelihood of developing cancer, as well as increased cancer-related death rates. This investigation, part of the UK Biobank project, analyzed data from more than 91,000 individuals who were cancer-free at the study's start. Participants had an average age of 56, and their health was tracked for nearly 12 years.

Physical activity levels were monitored using wrist-worn accelerometers. The study distinguished two patterns of inactivity: prolonged sitting (defined as 30 minutes or more with at least 90% inactivity) and interrupted sitting. Key findings include:

• Each extra hour of continuous sitting raises the risk of dying from cancer by 9%.
• The overall incidence of cancer increases by 3% for every additional hour spent sitting without breaks.
• The risk of cancers associated with obesity and type 2 diabetes climbs by 5% per hour of uninterrupted sitting.

The Protective Role of Taking Breaks

The research also highlighted that incorporating regular breaks during sitting periods offers significant health benefits. Taking breaks was found to lower the risk of cancer mortality by 18% and reduce overall cancer incidence by 6%. Moreover, replacing one hour of continuous sitting with light physical movement could decrease cancer death risk by 12%.

“Each additional hour of sitting without interruption considerably heightens the chance of developing and dying from cancer,” emphasized Frederick Ho, one of the study’s lead authors.

These findings underscore the critical importance of breaking up long periods of sitting with physical activity to mitigate cancer risks. Given that modern lifestyles-especially office environments-often involve extended sedentary behavior, adopting regular movement breaks can play a vital role in enhancing public health and preventing serious diseases.

In addition to the findings on prolonged sitting, maintaining a consistent daily routine has been linked to improved mental well-being. Research suggests that such routines can reduce pain and alleviate symptoms of depression, further highlighting the importance of an active lifestyle.
