Early-weaned BAN girls had significantly reduced weight velocity (0.02 vs 0.05 g/kg/day) and length velocity (0.73 vs 1.55 cm/month) compared to matched breastfeeding community girls between 15 and 18 months of age.
| Effect size | Weight velocity: 0.02 g/kg/day (BAN girls) vs 0.05 g/kg/day (community girls), p<0.05; Length velocity: 0.73 cm/month (BAN girls) vs 1.55 cm/month (community girls), p<0.05 |
| CI | Weight velocity BAN girls: 95%CI 0.01, 0.03; community girls: 95%CI 0.03, 0.07. Length velocity BAN girls: 95%CI 0.40, 1.06; community girls: 95%CI 0.98, 2.12 |
| Follow-up | 12 months |
| Comparator | Age-, gender-, and clinic-matched breastfeeding community girls (self-reported HIV-negative mothers) |
| Effect summary | decline; Weight velocity: 0.02 g/kg/day (BAN girls) vs 0.05 g/kg/day (community girls), p<0.05; Length velocity: 0.73 cm/month (BAN girls) vs 1.55 cm/month (community girls), p<0.05; CI: Weight velocity BAN girls: 95%CI 0.01, 0.03; community girls: 95%CI 0.03, 0.07. Length velocity BAN girls: 95%CI 0.40, 1.06; community girls: 95%CI 0.98, 2.12 |

Girls consumed less fat in their diet and families were 4 times more likely to buy milk products for boys.", "annotation_notes": "Authors hypothesize the sex difference may be due to differential feeding practices: families were 4x more likely to purchase milk for boys. Girls consumed 20% of calories from fat vs boys 24%."}] |
