Introduction: Evidence of an association between periodontitis and MetS (metabolic syndrome) remains controversial. The objective of this study is to evaluate the association between periodontitis and MetS in a cross‐sectional population survey. Material and Methods: WORALTH (Workers' ORAL healTH) Study is a cross‐sectional survey, conducted on a representative sample of the Spanish employed population, including 5154 participants. An oral examination following the World Health Organization (WHO) criteria evaluated the periodontal status using the Community Periodontal Index (CPI) and Clinical Attachment Levels (CAL). Logistic regression analysis with adjustment for potential confounders was used to evaluate the association between periodontitis and MetS, and its individual components. Results: Participants presenting a CPI = 4 were more likely to have MetS than subjects with CPI < 4 [odds ratio, OR = 1.41; 95% confidence interval (CI) 1.10–1.81; p < 0.001]. High blood pressure was the component with stronger association with periodontal status (OR = 1.94 for CAL ≥6 mm; 95% CI 1.49–2.53; p < 0.001). After stratifying for sex, the association was higher in women (OR = 2.20 for CPI = 4; 95% CI 1.31–3.62; p < 0.001). Non‐metabolically healthy subjects, obese or not, presented a worse periodontal condition. Conclusion: Severe periodontitis (CPI = 4) was associated with MetS in a representative sample of the Spanish employed population. This association seems to be independent of body mass index and other potential confounders. [ABSTRACT FROM AUTHOR]

This study analyzes associated factors to self-perceived oral health and use of oral health services in native and immigrant adults from the PELFI cohort in Spain. A cross-sectional analysis was conducted (401 adults ≥ 18 years, from Spain, Ecuador, Colombia and Morocco). Frequencies for sociodemographic, self-perceived general and oral health variables were calculated. The association between oral health/oral health services use and origin country was estimated by logistic regression (adjusted odds ratio-aOR-; 95% confidence intervals -95%CI-). Ecuadorian men were more likely to report dental caries (aPR 2.75; 95%CI 1.30–5.80) and Moroccan women were more likely to report gingival bleeding (aPR 3.61; 95%CI 1.83–7.15) and the use of oral health services ≥ 1 year/never (aPR 1.69; 95%CI 1.06–2.69). Colombian women were less likely to report missing teeth (aPR 0.73; 95%CI 0.56–0.95). Poor self-perceived oral health indicators were observed in immigrants and were modified for sociodemographic and general health variables. [ABSTRACT FROM AUTHOR]
