| Methods |
Design: controlled trial.
Quality assessment
Randomization: C.
Follow‐up: C.
Blinding: A for weight and maternal postpartum weight loss, B for length, developmental milestones, and lactational amenorrhea.
Jadad scale
Randomization: 0/2.
Double‐blinding: 0/2.
Withdrawals: 1/1.
Total Jadad scale score: 1/5. |
| Participants |
141 Honduran infants of low‐income families with poor sanitation. |
| Interventions |
EBF = BF with no other liquids or solids until 6 months (n = 50).
MBF = introduction of complementary solid food at 4 months with either ad libitum nursing (SF) or maintenance of baseline nursing frequency (SF‐M) (n = 91). |
| Outcomes |
Weight and length gain 4‐6 and 6‐12 months; WAZ, LAZ, and WLZ at 6 months; receipt of Fe supplements 6‐9 months; hemoglobin and ferritin at 6 months; % of days with fever, cough, nasal congestion, nasal discharge, hoarseness, and diarrhea; age first crawled, age first sat from lying position, walking by 12 months; maternal postpartum weight loss 4‐6 months; resumption of menses by 6 months. |
| Notes |
1. Nonrandom allocation.
2. Cluster allocation by week of birth, while analyses done at individual level.
3. Analysis not based on intention to treat.
4. SF‐M and SF groups combined as MBF group. |
