Association Between Metabolic Syndrome and Periodontitis: A Systematic Review and Meta-analysis
ABSTRACT Background:Several epidemiological studies have reported an association between metabolic syndrome (MetS) and periodontal diseases (PDs). The aim of this systematic review was to investigate the existence and magnitude of this association.Materials and Methods:A systematic search of the literature was conducted looking for case-control, cross-sectional, cohort studies and population surveys including patients with measures of MetS and PD. Ovid MEDLINE, EMBASE, LILACS, and Cochrane library databases were used for the search by 2 independent reviewers. A meta-analysis was conducted to investigate the association for coexistence of MetS and PD.Results:A total of 20 studies were included in the review, from an initial search of 3486 titles. Only 1 study reported longitudinal data on the onset of MetS components in association with periodontal measures. However, several studies investigated coexistence. A random effects meta-analysis showed that the presence of MetS is associated with the presence of periodontitis in a total of 36 337 subjects (odds ratio = 1.71; 95% confidence interval = 1.42 to 2.03). When only studies with "secure" diagnoses were included (n = 16 405), the magnitude of association increased (odds ratio = 2.09; 95% confidence interval = 1.28 to 3.44). Moderate heterogeneity was detected (I(2) = 53.6%; P = .004).Conclusions:This review presents clear evidence for an association between MetS and periodontitis. The direction of the association and factors influencing it should be investigated by longitudinal and treatment studies. Periodontal diagnostic procedures should be routinely carried out in MetS patients.

ABSTRACT: Each year, the American Heart Association (AHA), in conjunction with the Centers for Disease Control and Prevention, the National Institutes of Health, and other government agencies, brings together the most up-to-date statistics on heart disease, stroke, other vascular diseases, and their risk factors and presents them in its Heart Disease and Stroke Statistical Update. The Statistical Update is a critical resource for researchers, clinicians, healthcare policy makers, media professionals, the lay public, and many others who seek the best available national data on heart disease, stroke, and other cardiovascular disease-related morbidity and mortality and the risks, quality of care, use of medical procedures and operations, and costs associated with the management of these diseases in a single document. Indeed, since 1999, the Statistical Update has been cited >10 500 times in the literature, based on citations of all annual versions. In 2012 alone, the various Statistical Updates were cited ≈3500 times (data from Google Scholar). In recent years, the Statistical Update has undergone some major changes with the addition of new chapters and major updates across multiple areas, as well as increasing the number of ways to access and use the information assembled. For this year's edition, the Statistics Committee, which produces the document for the AHA, updated all of the current chapters with the most recent nationally representative data and inclusion of relevant articles from the literature over the past year. This year's edition includes a new chapter on peripheral artery disease, as well as new data on the monitoring and benefits of cardiovascular health in the population, with additional new focus on evidence-based approaches to changing behaviors, implementation strategies, and implications of the AHA's 2020 Impact Goals. Below are a few highlights from this year's Update.Circulation 12/2012; 127(1). DOI:10.1161/CIR.0b013e31828124ad · 14.95 Impact Factor

ABSTRACT: A growing body of evidence supports an association between oral health and cardiovascular diseases and diabetes in adults. This study aimed to investigate the relationship between tooth brushing frequency and cardiometabolic risk factors in adolescents. This nationwide population-based study was conducted among 5258 Iranian students, aged 10-18 years, living in urban and rural areas of 27 provinces in Iran. The association of tooth brushing frequency was assessed with anthropometric indexes and cardiometabolic risk factors after adjustment for potential confounders. Higher frequency of tooth brushing was associated with lower mean levels of low-density lipoprotein cholesterol (LDL-C) in both genders (P < 0.0001) and lower frequency of elevated LDL-C in girls (P = 0.03). The frequency of elevated blood pressure decreased with higher tooth brushing frequency in boys (P = 0.03). After adjustment for many potential cofounders such as age, gender, anthropometric indexes, screen time, socioeconomic status, and family history of non-communicable diseases, participants who washed their teeth at least once a day had lower risk of high LDL-C and low high-density lipoprotein cholesterol (HDL-C) levels in comparison to those who reported lower frequency of tooth brushing; some different associations were observed among girls and boys. Our findings suggest an independent and protective role of teeth brushing frequency for some cardiometabolic risk factors in adolescents. Increasing both the general health awareness and improving oral health should be considered in primordial and primary prevention of non-communicable diseases.International journal of preventive medicine 03/2013; 4(3):271-8.
