This study investigated whether obesity is linked with dental caries. This study hypothesized that obesity may influence the number or prevalence of dental caries in Korean adults.
Data were derived from Korea National Health and Nutrition Examination Survey performed at 2008-2010. Lifestyle, sociodemographic, and biochemical variables were analyzed. Indices related to obesity, sarcopenia, and metabolic syndrome were investigated. Finally, caries index and oral health behaviors were included for the analysis.
The caries index was inversely associated with increasing body mass index (BMI) and body fat quartile (all p-values <.01). Subjects with high waist circumference who met the inclusion criteria of metabolic syndrome were less likely to have decayed tooth (p-value = .0009). Subjects with a BMI of 25 or more showed about 20% less prevalence of dental caries experience than normal individuals with a BMI of 18.5 to 23 glucose (odds ratio [95% confidence intervals] = 0.808 [0.684-0.956]). Similarly, subjects with total body fat in the highest quartile revealed about 20% less prevalence of caries experiences that those with body fat proportion in the lowest quartile (0.84 [0.672,1.049]).
Obesity was inversely associated with occurrence or severity of dental caries in Korean adults.
本研究旨在探讨肥胖是否与龋齿有关。本研究假设肥胖可能会影响韩国成年人的龋齿数量或患病率。
本研究的数据来源于 2008-2010 年进行的韩国国家健康和营养检查调查。分析了生活方式、社会人口统计学和生化变量。研究了与肥胖、肌肉减少症和代谢综合征相关的指数。最后，纳入了龋齿指数和口腔健康行为进行分析。
龋齿指数与体重指数（BMI）和体脂肪四分位值的增加呈负相关（均 p 值<.01）。符合代谢综合征纳入标准的高腰围人群发生龋齿的可能性较小（p 值 =.0009）。BMI 为 25 或以上的受试者比 BMI 为 18.5 至 23 葡萄糖的正常个体发生龋齿的比例低约 20%（比值比[95%置信区间] = 0.808 [0.684-0.956]）。同样，体脂肪最高四分位数的受试者发生龋齿的比例比体脂肪最低四分位数的受试者低约 20%（0.84 [0.672,1.049]）。
肥胖与韩国成年人龋齿的发生或严重程度呈负相关。
