a BMI trajectories before self-reported diabetes diagnosis in adults with and without developing diabetes. Note: For the diabetes-free group, BMI = 23.073 + 0.080 * time - 0.002 * time². For the developing diabetes group, BMI = (23.073 + 1.294) + (0.080 + 0.150) * time-(0.002 + 0.008) * time²). b BMI trajectories before self-reported diabetes diagnosis in males and females with and without developing diabetes. Note: For female + diabetes-free group, BMI = 23.045 + 0.078 * time. For male + diabetes-free group, BMI = 23.075 + 0.084 * time - 0.002 * time². For female + developing diabetes group, BMI = (23.045 + 1.894) + 0.078 * time. For male + developing diabetes group, BMI = 23.075 + (0.084 + 0.163) * time -(0.002 + 0.008) * time². c BMI trajectories before self-reported diabetes diagnosis in individuals with and without developing diabetes by initial body size. Note: For BMI < 24 + diabetes-free group, BMI = 21.085 + 0.063 * time. For BMI ≥ 24 + diabetes-free group, BMI = 26.302 - 0.002 * time². For BMI < 24 + developing diabetes group, BMI = 21.085 + 0.063 * time. For BMI ≥ 24 + developing diabetes group, BMI = 26.302 + 0.209 * time - (0.002 + 0.009) * time²
