Study characteristics by BMI trajectory in boys: the birth to twenty cohort
| Normal weight (n = 813) | Trajectory 2 (n = 53) | Trajectory 3 (n = 11) | P value | |
|---|---|---|---|---|
| Study characteristics | ||||
| Birth weight (kg) | 3.1 (0.5) | 3.2 (0.6) | 3.2 (0 .7) | 0.46 |
| Height at 18 years (cm) | 170.6 (6.7) | 172.4 (5.5) | 170.4 (7.6) | 0.21 |
| SBP at 18 years (mm Hg) | 121.0 (10.8) | 124.2 (8.2) | 134.5 (16.9) | 0.00*** |
| DBP at 18 years (mm Hg) | 71.0 (8.6) | 71.9 (8.3) | 76.8 (8.7) | 0.09 |
| MAP at 18 years (mm Hg) | 87.7 (8.1) | 89.4 (7.3) | 96.0 (10.3) | 0.00** |
| Elevated BP n (%) | 276 (38.7) | 20 (46.5) | 6 (60.0) | 0.24 |
For boys: Trajectory 2 = Early Onset Overweight to Normal Weight, Trajectory 3 = Early Onset Overweight to Obese
Summary statistics presented as mean (±standard deviation) otherwise stated
*P < 0.05; **P < 0.01; ***P < 0.001
ANOVA and chi square test were conducted to describe the study characteristics differences in BMI trajectories
Percentages may not add up to 100 % due to rounding
