Oral health behavior at age of 11-12 years predicting educational plans at age of 15-16 years

Objective. The aim was to determine if oral health-related behavior at the age of 11-12 years predicts adolescents' educational plans at the age of 15-16 years when adjusting for gender and parents' occupational level. Materials and methods. The study population consisted of all fifth and sixth graders starting in the 2001-2002 school year in Pori, Finland (n = 1691); of these, 1467 returned properly filled questionnaires on behavior (toothbrushing and consumptions of xylitol products, candies, soft drinks and sports drinks) in 2001 and on educational plans in 2005. Parents' occupational levels were reported in 2001 by one of the parents of 1352 of these children. Associations between adolescents' educational plans and their behavior, gender and parents' occupation were evaluated using logistic regression model. Results. Children's oral health-related behavior at age 1112, gender and parent's occupational level predicted their educational plans at age 15-16. Association between educational plans and behavior, especially cumulative health behavior, remained statistically significant when controlling for gender and parent's occupation: OR = 1.4 for difference of one good habit, and OR = 5.3 for difference of five good habits. Conclusions. Since difference in oral health-related behavior can be seen already in primary school, even when controlling for parents' occupational level, polarization of adolescents may begin already in primary school stage or even earlier.
