Development in mean BMI SDS from childhood to adolescence according to weight class* at 2–4 years. Mean BMI SDS and 99 % CI at 2–4, 5–7 and 15–17 years of age in thin/normal weight and overweight/obese children at 2–4 years of age. BMI SDS is calculated using LMS values based on an international reference population of children [28]. A sub study of The Tromsø Study: Fit Futures N = 532. * Weight classes are based on BMI according to the International Obesity Taskforce’s age- and sex-specific cut-off values in children 2–18 years: thinness: adult BMI <18.5 kg/m2, normal weight: adult BMI ≥18.5- < 25 kg/m2, overweight: adult BMI ≥25- < 30 kg/m2, obesity: adult BMI ≥30 kg/m2 [28]. BMI: body mass index, SDS: standard deviation score, CI: confidence interval, IOTF: International Obesity Taskforce, LMS: LMS curves/ LMS method: median (M), coefficient of variation (S) and skewness (L)
