Relationship between Behavioral-Related Variables and Dental Caries Prevalence Among University Students: A Cross-Sectional Study
Abstract
Background: Dental caries is a highly prevalent oral health problem among young adults. University students are particularly at risk due to lifestyle changes, irregular dietary patterns, and inadequate oral hygiene practices. This study assessed the association between behavioral factors and dental caries among university students.
Study Design: A Cross-sectional study.
Place and Duration of the Study: The study was conducted at University of Peshawar, over a period of six months from January 2024 to June 2024.
Materials and Methods: A total of 300 university students were selected through stratified random sampling. Data were collected using a structured self-administered questionnaire covering socio-demographic characteristics and oral health behaviors, including tooth brushing frequency, sugary snack intake, flossing, smoking/vaping, and dental visits. Clinical examinations were conducted to determine the presence of dental caries. Data were analyzed using descriptive statistics, Chi-square tests, and multivariable logistic regression. Adjusted odds ratios (AORs) with 95% confidence intervals (CIs)were calculated, andp < 0.05 was considered statistically significant.
Results: The prevalence of dental caries was 62.0%. Brushing less than once daily significantly increased caries risk (AOR = 4.85; 95% CI: 1.90–12.40). High sugary snack consumption (≥4 times/day) was strongly associated with caries (AOR = 3.60; 95% CI: 1.75–7.42). Lack of dental visits within the past year…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
