Impact of a high-sugar diet and socioeconomic conditions on caries experience in children and young adults

Abstract

Objective: to evaluate the association between the prevalence of dental caries, sugary food intake and socioeconomic conditions of children and young adults. Material and methods: socioeconomic questionnaires were applied to parents and/or guardians of 36 children and adolescents attending a soccer club in the city of Alegre – ES, Brazil, aged between 7 and 20 years. To assess food intake, a Food Frequency Questionnaire (FFQ) was applied. Tooth decay was assessed using the Decayed, Missing, Filled Teeth Index (DMFT) and plaque through the Simplified Oral Hygiene Index (OHI-S). Subsequently, lectures and oral hygiene and nutritional education activities were held. The plaque index was then reevaluated two weeks after the intervention. The presence of caries was expressed using relative frequency. In order to evaluate the factors associated with dental caries, a logistic regression model was used (p <0.05), and to evaluate the effect of the intervention, the paired t-test was used to compare the plaque index. Results: 67% out of the assessed children had past and current history of decay, with a median DMFT of 2. Among the variables assessed ‘family income’, ‘parents’ educational level’ and ‘consumption of high-sugar foods’ no statistically significant association (p <0.05) with the presence of dental caries was observed. To valuate the bacterial plaque index, it was observed that the intervention was effective (p <0.05) with an initial OHI-S of 1.98 and final of 1.43. Conclusion: a high prevalence of polarized DMFT was found in the sample. The health education actions were effective in reducing plaque. Almost all of the sample was found to have the habit of consuming sugary food four or more times a week. No significant associations were found between dental caries and the variables analyzed
