Prevalence and Associated Factors of High BMI and Periodontitis in Thai Adults Aged Under 60 Years

Overweight and obesity, as well as periodontitis, are common public health problems with increasing prevalence. Both conditions may be linked through shared mechanisms involving chronic low-grade systemic inflammation. Numerous studies have reported an association between elevated body mass index (BMI) and periodontitis, particularly among younger and working-age populations. However, data regarding Thai adults under the age of 60 remain limited. Therefore, this study aims to determine the prevalence of high BMI and periodontitis among Thai adults aged 18-59 years and to identify factors associated with these conditions. The findings may provide useful information for improving awareness and supporting the prevention of both periodontal and general health problems in this population.
