Unravelling behavioural contributions to IBS risk: evidence from univariate and multivariate Mendelian randomisation

This study identified BMI, insomnia, duration of mobile phone use, and weekly mobile phone usage time in the past three months as risk factors for IBS. In contrast, weekly alcohol consumption, usual walking pace, and non-smoking status were observed as protective factors. Additionally, in multivariable analysis, weekly mobile phone use, insomnia, and weekly alcohol consumption showed a direct influence on IBS risk when considered simultaneously.
