Hypothesis

Does peer counselling for exclusive breastfeeding and vitamin A supplementation affect malaria parasitaemia in infants?

Conclusion

Peer counselling for exclusive breastfeeding did not decrease the prevalence of malaria parasitaemia, and children not receiving Vitamin A supplementation had a higher prevalence of malaria.

Supporting Evidence

  • The prevalence of malaria parasitaemia was 11% in the intervention areas and 10% in the control areas.
  • Infants not supplemented with Vitamin A had a higher prevalence of malaria compared to those who had been supplemented.
  • Every unit increase in length-for-age Z scores was associated with a reduced prevalence in malaria among children supplemented with vitamin A.

Takeaway

This study looked at whether breastfeeding help and vitamin A could protect babies from malaria. It found that breastfeeding help didn't work, and babies who didn't get vitamin A were more likely to get malaria.

Methodology

A cluster randomized trial was conducted in Eastern Uganda, where 12 clusters received peer counselling for exclusive breastfeeding and 12 served as controls. Blood samples were collected from 483 infants to test for malaria parasitaemia.

Potential Biases

Potential bias due to the inability to fully blind participants and data collectors in a community trial.

Limitations

The study's generalizability is limited as clusters were close to main roads, and the diagnosis of malaria was based on microscopy, which has low sensitivity.

Participant Demographics

Infants aged 3 to 12 months, with a mean maternal age of 25 years and an average of 6 years of formal education.
