Correlation Between BMI, Caries Prevalence, and Sugar-containing Beverage Intake in 6-10 Year Old Children

The beverages containing sugar are proven risk factors for obesity and dental caries. Therefore, owing to the shared risk factors, an interrelationship is suspected between BMI, sugar beverage consumption, and dental caries in children.

The present trial was carried out to assess the interrelationship between BMI, sugar beverage consumption, and dental caries in children aged 6-10 years.

Eighty-six children within the age range of 6-10 years answered the health questionnaire. The BMI was calculated, intra-oral assessment was done, the frequency of sweetened beverage consumption was recorded, and the collected data were subjected to the statistical evaluation to formulate results.

On evaluation, a non-significant difference was observed in BMI levels in the four groups (P = 0.12). Whole-milk intake also showed an inverse correlation with dental caries and BMI, but this correlation was statistically non-significant with the respective values of P = 0.57 and 0.55. A similar inverse relationship was seen for low-fat milk for caries and BMI with P = 0.65 and 0.45, respectively. Regarding soft drinks, 44.1% (n = 38) took soft drinks, and a non-significant relation between caries and intake as well as BMI and intake with P = 0.86 and 0.55, respectively.

Within its limitations, the present study concludes that no correlation exists between BMI and dental caries as well as between sugar-containing beverage consumption and dental caries. Also, BMI and sugar-containing beverage consumption showed no correlation in children aged 6-10 years.
