The role of correlated factors based on Pender health promotion model in brushing behavior in the 13-16 years old students of Guilan, Iran.

BACKGROUND

Tooth decay is one of the diseases that is closely related to people's behaviors and it can have adverse effects on their performance and their success in the future. Brushing twice a day is the simplest and most effective way to reduce tooth decay. The study aim was to determining the roles of correlational factors based on the Pender's health promotion model in brushing behavior of ninth grade students at urban public schools of Guilan province during the academic year 2019.

METHODS

The present study was cross-sectional and had a descriptive-analytical type. We performed the multi-stage random sampling on 761 ninth-grade students (374 girls and 387 boys) at urban public schools of six counties (ten cities) of Guilan province in 2019. The primary tool was a questionnaire on oral health behaviors focusing on brushing behavior. In the present study, which was conducted only on brushing behavior, we revised and changed the initial questionnaire during the sessions of the research team, and then confirmed its validity and reliability. The questionnaire consisted of three parts, demographic characteristics, constructs of health promotion model, and brushing behavior. We analyzed data in SPSS 21 using regression models.

RESULTS

20.1% of students brushed their teeth at least twice a day. Optimal behavior had a statistically significant relationship with parents' education level, and gender. Based on the regression model, the health promotion model constructs described 58% of the variance of the commitment to plan of action. Perceived self-efficacy, situational influences, and perceived barriers of action had significantly stronger relationships with commitment to plan of action respectively. Multiple logistic regression analysis indicated that one-unit increase in scores of commitment to plan of action and self-efficacy increased the chance of desired behavior by 12 and 14% respectively.

CONCLUSION

Due to the low rate of brushing behavior in the students and the predictive power of the health promotion model in brushing behavior, we suggest planning and implementation of educational interventions for this group with an emphasis on influencing the commitment to plan of action, self-efficacy, and also the level of knowledge.
