Hypothesis

Does repeated four-monthly albendazole treatments reduce soil-transmitted helminth infections in preschool children?

Conclusion

The study found that repeated four-monthly treatments with albendazole significantly reduced the prevalence and intensity of Ascaris lumbricoides infections in preschool children.

Supporting Evidence

  • 50% of preschool children were infected with one or more helminths at baseline.
  • The most prevalent STH was Ascaris lumbricoides, affecting 47.6% of children.
  • Mean egg count (epg) for A. lumbricoides dropped from 1095 at baseline to 117 at 14 months in the treatment group.
  • 12% of children in the treatment group were infected with A. lumbricoides at the end of the study compared to 43% in the placebo group.

Takeaway

Giving kids medicine every four months can help get rid of worms in their tummies and make them healthier.

Methodology

The study was a double-blind placebo-controlled randomised trial conducted in four semi-urban villages in Nigeria, with children aged 1-4 receiving either albendazole or placebo every four months for 12 months.

Potential Biases

Potential bias due to loss to follow-up, although baseline characteristics were similar between those lost and those analyzed.

Limitations

High attrition rate (68.4%) and non-random selection of subjects may affect the generalizability of the results.

Participant Demographics

Children aged 1-4 years from semi-urban communities in Nigeria, predominantly Yoruba-speaking.
