Obesity and dental caries in Saudi Arabia: a correlated study

BackgroundObesity and dental caries are two major global public health concerns. There have been conflicting reports about the relationship between obesity and dental caries. This study intends to examine the link between obesity and dental caries across the five regions of Saudi Arabia. MethodsThe study involved 380 participants, which was a cross-sectional survey, with an age range of 6 to 14. We distributed a self-reported questionnaire to assess the participants body mass index (BMI) and caries (dmft/DMFT). In this study, descriptive analysis, student t-test, one-way analysis of variance (ANOVA), and multiple linear regression analysis were used. ResultsThe study comprised 380 respondents, consisting of females (60.8%) and males (39.2%), with a mean age of 9.1 years and mean BMI of 26.3. The prevalence of caries among the study respondents was 66.6% (Table 2), and this prevalence was higher among females (67.5%), those who consumed sugar more than six times (77.5%), those who brushed their teeth once per day (80.3%), those who used no dental floss (68.4%), those who did not use mouthwash or rinse (68.4%), and those in the east and center regions (100%). The obese possess a statistically significant (P < 0.05) higher mean dmft/DMFT (dmft = 8.00 and DMFT = 6.00). Furthermore, BMI had a negative influence on the DMFT score (b = -0.01, P = 0.776), which was not statistically significant. ConclusionParticipants categorized as obese demonstrated a notably higher mean dmft/DMFT in comparison to their non-obese counterparts. Although BMI showed a negative impact on the DMFT score, this association did not reach statistical significance.
