Abstract
Objective

We conducted a cluster-randomized controlled trial to assess the efficacy of a cereal made from caterpillars, a micronutrient-rich, locally available alternative animal-source food, on reducing stunting and anaemia in infants in the Democratic Republic of Congo.

Design

Six-month-old infants were cluster randomized to receive either caterpillar cereal daily until 18 months of age or the usual diet. At 18 months of age, anthropometric measurements and biological samples were collected.

Setting

The rural Equateur Province in the Democratic Republic of Congo.

Subjects

One hundred and seventy-five infants followed from 6 to 18 months of age.

Results

Stunting was common at 6 months (35 %) and the prevalence increased until 18 months (69 %). There was no difference in stunting prevalence at 18 months between the intervention and control groups (67 % v. 71 %, P=0·69). Infants in the cereal group had higher Hb concentration than infants in the control group (10·7 v. 10·1 g/dl, P=0·03) and fewer were anaemic (26 v. 50 %, P=0·006), although there was no difference in estimates of body Fe stores (6·7 v. 7·2 mg/kg body weight, P=0·44).

Conclusions

Supplementation of complementary foods with caterpillar cereal did not reduce the prevalence of stunting at 18 months of age. However, infants who consumed caterpillar cereal had higher Hb concentration and fewer were anaemic, suggesting that caterpillar cereal might have some beneficial effect. The high prevalence of stunting at 6 months and the lack of response to this micronutrient-rich supplement suggest that factors other than dietary deficiencies also contribute to stunting.
