Development of overweight/obesity (A) and impaired glucose tolerance/type 2 diabetes (IGT/T2D) (B) according to categories of standing time over the 6-year follow-up period in adults. Data are presented as percentage. Overweight/obesity was defined as a body mass index ≥25 kg/m2. Impaired glucose tolerance/type 2 diabetes was defined according to the American Diabetes Association and the World Health Organization criteria [26,27]. Statistical significance was assessed by a chi-squared test (P < 0.05 for all analyses). Standing categories: rarely/never (n = 97), half of the time (n = 66), most of the time (n = 57) and all the time (n = 73).
