avje otrok in mladostnikov | health of children and adolescents 20 The interpretation of the results was based on the number and propor-
tions of people in the selected categories, according to demographic variables
(gender, age, education of parents/guardians, living environment) or other var-
iables that were determined according to the research needs or for planning
further measures.
Methods of analysis
The data obtained from the study were weighted by gender and age, consider-
ing one-year age groups. The analysis of sample and population weighted da-
ta was performed in the computer programs IBM SPSS Statistics for Windows,
version 21.0 (2020) and R program, version 3.6.0 (n. d.).
The distributions of proportions between different groups (by gender or
age) and comparisons were tested using the chi-square test and the CCP test
(Column Comparison Proportion test) to compare proportions between dif-
ferent groups. In both cases, we used a 95% confidence interval in order to be
able to assess the studied situation (Benjamini and Hochberg, 1995; IBM, 2017).
Results
Among the 3,200 selected persons, 3,164 were suitable (these persons could
be reached at the addresses that were accessible to us). The questionnaire was
completed by 1,406 parents or adolescents, which represented a response rate
of 44%, namely in the age group 0–5 years 43% (469 children), in the age group
6–10 years 46% (465 children) and in the age group 11–17 years 45% (472 ado-
lescents).
Frequency of teeth cleaning
We found out that only 62% of children aged 0–5 brushed their teeth regularly
(or their parents helped them). The proportion of children who brushed their
teeth regularly is the smallest among children under the age of 1; parents regu-
larly brushed the teeth of only 30% of children up to the age of 1. Among chil-
dren aged 1–4 years, the proportion increased to 65% (Figure 1).
The proportion of children who brushed their teeth regularly increased
slightly after the age of 5, namely 80% of children brushed their teeth regular-
ly. On average, 20% of children/adolescents did not brush their teeth regularly
between the ages of 6–10 and 11–17.
For children aged 0–10 years who brushed their teeth regularly, we noted
that the differences in the proportion between boys and girls were not statis-
tically significant. Among adolescents aged 11–17, 86% of girls and 74% of boys
brushed their teeth regularly; differences in the proportion between genders
were statistically significant (chi-square test = 9.517, p = 0.002; CCP test, p =
0.02). The biggest (statistically significant) differences were seen among adoles-
tions of people in the selected categories, according to demographic variables
(gender, age, education of parents/guardians, living environment) or other var-
iables that were determined according to the research needs or for planning
further measures.
