Monitoring the impact, trends, and impact levels of factors affecting Pediculus capitis infestation in primary school students: An illustrative scale of evidence review.

Purpose: This study examined the impact, trends, and impact levels of factors affecting Pediculus capitis infestation in primary school students. Subject and methods: Among the papers reviewed, 226 were selected, as they contained information that suited the study objectives. Results: The factors whose trends have higher gradients have a higher impact on the infestation level. In order of impact, the gradients of hair washing frequency, health instructor involvement, bathing frequency, mother's and father's education, existence of bathing facility, family size, hairstyle, and family income trends are higher than hair length, and age and education trends. As a result, the factor impacts are diminished from the beginning to the end. The importance of the family size, father's and mother's education, bathing facility existence, health instructor involvement, and bathing and hair washing frequency factors, whose trends increased over time, is higher than family income, hairstyle and length, and age and education, whose trends remained constant or decreased. Based on the gradient of the factor level impact trends, it seems that hair washing frequency, father's and mother's education, and health instructor involvement are the factors with the greatest effects on infestation level, in that order. These are followed by the influence of family income and size, and hairstyle factors. The existence of bathing facilities, bathing frequency, hair length, and education factors have weaker effects. Conclusion: This work provides the importance and impact levels of factors affecting Pediculus capitis infestation levels in primary school students, which will help meet the needs of policymakers.
