Abstract
Aim: Because metabolic syndrome (MS) is pro-inflammatory and periodontitis is
inflammatory, we issued the hypothesis that MS (the explanatory variable) is
associated with periodontitis (the outcome variable). This study aimed to examine the
link between MS and periodontitis among Koreans.
Materials and Methods: From the Shiwha–Banwol Environmental Health Study,
1046 subjects aged 18 years or older were cross-sectionally surveyed. All participants
underwent comprehensive dental and medical health examinations. The community
periodontal index was used to assess periodontitis. Age, gender, monthly family
income, smoking, drinking, frequency of daily teeth brushing, and physical activity
were evaluated as confounders.
Results: MS was strongly associated with periodontitis [odds ratio (OR): 1.7, 95%
confidence interval (CI): 1.22–2.37], and MS with more components had a higher
association. The association was higher for elders aged 65 years or more, males, and
smokers. MS including both high glucose and hypertension had a higher association
with the OR of 2.19 (95% CI: 1.23–3.90) comparing with other types of MS.
Conclusions: Our results suggested that MS might be associated with periodontitis
and the association was confounded by age, gender, and smoking. MS with high
glucose and hypertension showed the higher impact on this link.
