The current study was conducted to answer questions about the health and development of a community based sample of children as they became of school age.
However, this study did examine a broad variety of problem behaviors derived from a population-based sample of school children.
In a population-based sample of school-age children, we investigated factors associated with rhinitis, and differences between allergic and nonallergic rhinitis.
We aimed to investigate the risk factors for rhinitis in a population-based sample of school-age children participating in an unselected birth cohort and whether there are differences in risk factors between allergic and nonallergic rhinitis.
But, as one would expect from a population based sample, most high school students 73-800%), regardless of gender, did not have problems with any form of aggression.
This indicates that the school based sampling was very helpful in achieving a high response rate, compared to the pattern of sending questionnaires directly to parents all over Greece, without their being enforced by school authorities.
Although the present study is not based on representative sample of public school children in Nepal (as it uses convenient sampling) it does give an insight into the caries prevalence, oral health knowledge and preventive practice in rural public schools.
Methodology: The methodology employed a mixed method consisting of desk reviews of all programme documents including reports of both the term and sentinel reports; a qualitative component consisting of key informant interviews and focus group discussions; and a quantitative component based on a survey from a representative sample of schools and students.
Our study was based on a large sample drawn from a representative sample of schools.
First, as the survey sample base consists of school attendees, the surveys are not representative of all Italian youths aged 11, 13, and 15 (HBSC) and 13 15 years (GYTS).
The sample of schools was drawn from a computerized list of 404 schools, in a stratified random sample of schools proportionate to school size.
