  1. BMI: body mass index; IBS = irritable bowel syndrome; n = number. Sensitivity analysis, with participants using drugs associated with IBS excluded [30]. The prevalence in each group is presented as numbers and percentages. Logistic regression. Values are given as odds ratio (OR) and 95% confidence interval (CI). Bold values are statistically significant, with a p-value < 0.05
  2. *Divided into light (sitting or standing), intermediate (walking and lifting < 5 kg) and hard (increased breading). **Divided into sedentary (< 120 min/week, without sweating), moderate (move around ≥ 120 min/week, without sweating), moderate but regularly (≥ 30 min/week, sweating) and regularly (≥ 90 min/week, sweating)
