Abstract
Background Sugar-sweetened beverages are one of the most common sources of added sugar in the diet and have been associated with an increased risk ofdental caries, obesity, major chronic diseases, and possibly cancer. Dental caries is a diet-related, highly prevalent, and preventable oral disease.The objective of this study was to assess the frequency of sugar-sweetened beverage consumption and its association with dental caries in adolescents in Erbil, Iraq. Methods This is a cross-sectional study that invited 11- to 16-year-old intermediate school students (n=380) in Erbil, Iraq. Data collection comprised a validated questionnaire and a clinical examination.In addition, dietary data were collected by using two non-consecutive 24-hour recalls. The mean of the daily consumption of sugar-sweetened beverages over a two-day period was calculated.Dental caries was diagnosed based on World Health Organization (WHO)criteria and was reported as a decayed, missing, and filled permanent tooth (DMFT). A multiple regression model was used to assess the influence of sugar-sweetened beverages on dental caries experience (DMFT). SPSS version 26 (Armonk, NY: IBM Corp) was used to analyze the data at the 5% significance level. Results Of the 380 students interviewed, one participant was excluded because of incomplete data. The participant's mean age and standard deviation (SD) were 13.3±1.2. A total of 54.1%of the students were female. The mean daily intake of sugar-sweetened beverages was 686.71±197.50 mL per day.Male students consumed more beveragesthan femalestudents (p<0.001). The most frequently consumed sugar-sweetened beverages were sweetened tea and coffee, and the least frequently consumed beverages were milk and dairy products. The mean decayed, missing, and filled permanent tooth (DMFT) was 94.58±2.73.Results of multiple regression analysis showed that caries experience (DMFT) was associated with insufficient toothbrushing (p<0.001), plaque-affected sextants (p=0.001), and male sex (p=0.016). The model also showed a significant association between sugar-sweetened beverage consumption and dental caries experience (DMFT) (regression coefficient=0.008, CI: 0.006-0.009, p<0.001). Conclusions Adolescents in Erbil, Iraq, consumed sugar-sweetened beverages on a frequent basis, and male students consumed more sugary beverages than females. The higher frequency of these beverage consumptions was associated with a higher dental caries experience. Consequently, reducing sugar-sweetened beverage consumption could have a significant positive public health impact.
