Objective: Determine the association between key dental outcomes and added sugar intake using a survey instrument to assess added sugars, which was specifically tailored to immigrant and US-born adults of Mexican origin.
Methods: Hispanic adults of Mexican origin (n = 326; 36.2 ± 12.1 years) completed a self-administered survey to gather acculturation, self-reported dental experiences and self-care practices (eg brushing, flossing, pain, bleeding gums), and socio-demographic information. The survey included a culturally tailored 22-item Added Sugar Intake Estimate (ASIE) that assessed added sugar intake from processed foods and sugar-sweetened beverages in a semiquantitative food frequency questionnaire format. Linear regression, 2-sample t test, and ANOVA were used to evaluate associations of demographic and dental outcomes with daily added sugar intake.
Results: Of the mean total daily added sugar intake (99.6 ± 94.6 g), 36.5 ± 44.4 g was derived from sugar-containing foods and snacks, and 63.1 ± 68.2 g from beverages. Participants who reported greater added sugar intake were more likely to have reported the presence of a toothache in the preceding 12 months, having been prescribed antibiotics for dental reasons, being less likely to floss daily, have reported eating or drinking within 1 hour before bed and have lower psychological acculturation (P < .05 for all). Results were comparable when assessing intake from sugar-containing foods/snacks and sugar-sweetened beverages.
Conclusions: This study confirmed the association between added sugar intake and self-reported dental outcomes among adults of Mexican origin and points to an urgent need to improve dietary behaviours in this population.
