ABSTRACTBackground: pediculosis capitis is common among children worldwide. Concerns about toxicity of treatment with pesticides and resistance have led to alternative treatments.
Objective: to evaluate the effectiveness of natural coconut oil for treatment of pediculosis capitis.
Material and method: a cluster randomized controlled trial was carried out in eight public pre-schools in Acapulco, Guerrero, Mexico. After randomization, we selected four pre-schools for studying and four as controls. 30 ml of coconut oil were applied to the scalp of the children twice a day with a 10-day interval. This analysis aimed to estimate the impact of the coconut oil treatment.
Results: the study group was much less likely to have infestation in the follow-up examination than children in control group (odds ratio 0.27, cluster adjusted 95% confidence interval 0.11-0.69). The treatment significantly reduced levels of infestation (risk difference 9.3%; number needed to treat 11, 95% ci 7-21). Affected children in the study showed significantly lower loads of Pediculus humanus capitis compared with those in control schools (p ‹0.0001).
Conclusions: school-based application of natural coconut oil was effective in the treatment of pediculosis capitis.
