| Weight-for-length z score | ||||

| Overweight/obese (>2 z score) | 6.2 (10) | 25.9 (42) | ||
| Change in weight-for-length z score1 | Overall | By weight status at initial visit | ||
| Underweight | Adequate | Overweight | ||
| Slow weight change (<−0.67 SD) | 13.0 (21) | 0 | 10.7 (15) | 60.0 (6) |
| Adequate weight gain (−0.67 to 0.67 SD) | 27.8 (45) | 0 | 30.7 (43) | 20.0 (2) |
| Rapid weight change (>0.67 SD) | 59.3 (96) | 100 (12) | 58.6 (82) | 20.0 (2) |
1 Only two infants were categorized as underweight at the follow-up visit, therefore, they were excluded from the analysis.
