HRs and 95% CI according to change in BMI z-score between the ages of 7 and 13 years, adjusted for BMI z-score at 7 years of age, in relation to routinely diagnosed NAFLD in adulthood for (A) boys and (B) girls. (A) Boys: HR of adult NAFLD per 1-unit increase in BMI z-score between 7 and 13 years of age among boys: 1.15 (95% CI 1.05 to 1.26). (B) Girls: HR of adult NAFLD per 1-unit increase in BMI z-score between 7 and 13 years of age among girls: 1.12 (95% CI 1.02 to 1.23). The associations are adjusted for BMI z-score at 7 years of age and stratified by birth cohort. The HRs in figure 2 are estimated by Cox regression including change in body mass index (BMI) z-score between the ages of 7 and 13 years, as a restricted cubic spline, with a reference point in change in BMI z-score equal to 0, and truncated to depict the inner 99% part of the distribution. NAFLD, non-alcoholic fatty liver disease.
