Study divided in three groups:
- First group: samples of hair cut were collected and then the presence of the parasite was observed.
- Second group: the individuals’ heads were checked manually, and, after that, their hair was cut, taken to the laboratory, and examined.
- Third group (elderly): the individuals’ heads were examined. |

The infestation rate among children up to 15 years old was significantly higher than the rate observed among older groups (p = 0.013).
In the second group, the prevalence rate found using head inspection (20.6%) was seen to be significantly higher than the rate using cut hair (10.6%) (p = 0.022).
There was difference between the rates found among children (24.2%) and among adults (10.6%) in the second group of people (p = 0.045). |

The highest prevalence of infestation occurred in girls (p < 0.005). The influence of hair length on the prevalence of pediculosis showed a higher rate among children with long hair (p < 0.005). Children aged between 4-5 years were more affected than the others (p < 0.05). When comparing the rates verified for each school, regardless of location in the city, differences were observed between the prevalences (p < 0.005). The two highest prevalences observed (preschools V and III) were significantly different from the two lowest rates included in the comparison (preschools VI and II) (p < 0.05). |
