Pooled analyses of physical activity at 3 years and later risk for inflammatory bowel disease. Adjusted hazard ratio (aHR) accounted for child's sex, parental/maternal origin, parental IBD, maternal immune‐mediated comorbidities (any insulin‐treated diabetes: type 1 or gestational, rheumatoid arthritis or autoimmune thyroid disease), educational level, and smoking during pregnancy. Combination exposure reflects only individuals who had “High PA + Low ST” versus “Low PA + High ST”; the number of participants is lower due to ignoring children who had low PA + low ST level and high PA + high ST level. Numerical exposure of PA/ST examines the level of PA/ST using the original data distribution in hours per day. CI, confidence interval; h, hours; HR, hazard ratio; PA, physical activity; ST, screen time.
