Dental caries and adolescent cardiometabolic health from the National Health and Nutrition Examination Survey (NHANES).

Background and aims: To assess the association between dental caries and cardiometabolic risk in adolescents.

Methods and results: The analysis included adolescents aged 13-17 years enrolled in the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2018 who completed an Oral Health Examination. Untreated caries was defined as having one or more decayed teeth. Caries experience was assessed by Decayed, Missing, Filled Teeth (DMFT) score. Primary cardiometabolic outcomes included elevated BP (defined as BP 120-129/<80 mmHg) and hypertensive BP (defined as BP ≥ 130/80 mmHg). Secondary cardiometabolic outcomes included obesity, dyslipidemia (defined as any abnormal lipid level), glucose intolerance (measured by HOMA-IR), and microalbuminuria (defined as urine albumin: creatinine ≥30 mg/mg). Adjusted linear and logistic models examined associations using complex survey design procedures. In the sample of 2861 adolescents, 25.6 % (1.3 %) had untreated caries. 55.4 % (1.3 %) had DMFT ≥1. In adjusted regression analyses, untreated caries status was not significantly associated with primary outcomes of elevated BP (OR = 1.04, 95 % CI 0.71, 1.52 p > 0.05), hypertensive BP (OR = 1.72, 95 % CI 0.71, 3.89 p > 0.05), nor secondary cardiometabolic outcomes. No statistically significant associations were found between DMFT score and primary outcomes of elevated BP (OR = 0.01, 95 % CI 0.34, 1.07 p > 0.05), hypertensive BP (OR = 0.91, 95 % CI 0.81, 1.08 p > 0.05), or secondary cardiometabolic outcomes.

Conclusion: Although studies in other countries and in adults show associations between caries and cardiometabolic outcomes, this study did not find an association between caries and cardiometabolic markers.
