Body mass index z‐scores (zBMI), waist circumference, waist‐to‐height ratio percent body fat based on clinical measurements. Multiple linear regressions estimated associations. Results In childhood, early adolescence adolescence, 14%, 6%, 0% of participants met guidelines, respectively. Meeting fewer guideline components was cross‐sectionally associated higher each visit. in longitudinally later visits. For example, those meeting none (vs all) had a 1.66 SD (95% CI: 0.42, 2.89) zBMI Conclusion Few guidelines. Not is 2 7 later. Interventions needed increase across
