ABSTRACT:To estimate the prevalence and related aspects of periodontitis in a rural area of the State of Bahia, Brazil, this cross-sectional study was carried out in the village of Matinha dos Pretos, Feira de Santana County, Bahia, among 172 subjects ranging from 20 to 60 years of age. During household visits, a full-mouth periodontal exam was performed on each subject, who also answered a questionnaire about socio-demographic, economic and health-related issues. The factors assessed were plaque index, bleeding on probing index, probing depth, gingival recession or hyperplasia measurements. Clinical attachment loss was also calculated. The multivariate logistic regression method was used to evaluate the relative contribution of these factors to the periodontitis condition. The prevalence of periodontitis was 24.4%. The following factors were all positively associated with the presence of periodontitis: being male (OR = 1.58; 1.00 -2.53), being 30 years of age or older (OR = 2.80; 1.00 -7.39), living in a house where there was more than one person per room (OR = 1.53; 0.96 -2.45), being a cigarette or pipe smoker or ex-smoker (OR = 1.49; 0.92 -2.39), having a plaque index of over 65% (OR = 2.97; 2.72 -7.39) and more than four missing teeth (OR = 1.51; 0.82 -2.78). The authors concluded that socioeconomic and biological factors, especially poor oral hygiene and older age, are positively associated with periodontitis in the rural population of a small village in the county of Feira de Santana, State of Bahia, Brazil. DESCRIPTORS: Periodontitis; Prevalence; Risk factors.RESUMO: Para estimar a prevalência e os fatores associados à periodontite em uma área rural do Estado da Bahia foi realizado um estudo transversal com 172 indivíduos, de 20 a 60 anos de idade residentes no povoado de Matinha dos Pretos, Feira de Santana (BA). Durante visitas domiciliares, um exame clínico periodontal completo foi realizado para cada indivíduo, que também respondeu a um questionário a respeito de fatores sociodemográfi cos, econômicos e relacionados à saúde. Foram avaliados índice de placa, índice de sangramento à sondagem, profundidade de sondagem, medidas de recessão ou hiperplasia e calculada a perda de inserção clínica. Utilizou-se análise de regressão logística multivariada para avaliar a contribuição relativa desses fatores para a periodontite. A prevalência da doença periodontal foi de 24,42%. Ser homem (OR = 1,58; 1,00 -2,53), ter 30 anos ou mais de idade (OR = 2,80;1,(0)(1)(2)(3)(4)(5)(6)(7)39), residir em casas com mais de uma pessoa por cômodo (OR = 1,53; 0,96 -2,45), fumar ou ser ex-fumante de cigarro ou cachimbo (OR = 1,49; 0,92 -2,39), ter índice de placa maior do que 65% (OR = 2,97; 2,72 -7,39) e mais de quatro dentes ausentes (OR = 1,51; 0,82 -2,78) estiveram associados positivamente com a presença de doença. Concluiu-se que fatores socioeconômicos e biológicos, especialmente a higiene bucal inadequada e idade elevada, estão associados positivamente com a presença de periodontite na população rural de um povoado no Es...
Objective The objective of this study was to investigate an association between obesity (exposure) and periodontitis (outcome) in pregnant women. Background This association was investigated and only five studies were identified as showing a positive association. However, some of these studies had limitations such as reduced sample sizes, inadequate exposure criteria and outcome measures, which question the internal validity of these investigations. Methods A cross‐sectional study was carried out with a sample of 644 pregnant women of the public health service of the municipality of Santo Antônio de Jesus, Bahia, Brazil. Data were obtained by collecting of socioeconomic‐demographic information, health behavior, health conditions, and reproductive history through an interview. Obesity was evaluated using body mass index adjusted for gestational age and expected weight gain. The diagnosis of periodontitis followed two criteria: (a) Center for Disease Prevention and Control and American Academy of Periodontology (CDC/AAP); (b) Gomes‐Filho et al (2018) using criterion that also evaluated bleeding upon probing; Prevalence ratios and respective 95% confidence intervals were obtained by Poisson regression analysis. Results In accordance with the outcome diagnostic criterion, the frequency of periodontitis was 17.24% (Gomes‐Filho et al) and 66.92% (CDC/AAP). The participants were classified as low weight (19.72%), adequate weight (42.39%), overweight (24.84%), and obesity (13.04%), based on the exposure diagnostic criterion. The low weight and overweight groups were excluded from the data analysis, giving a final sample of 357 pregnant women. The association between obesity in pregnant women and periodontitis was not statistically significant, after adjusting for confounders such as age, schooling level, alcoholic beverage consumption, alimentary and nutritional orientation, urinary infection, and dental flossing. Conclusions The findings showed a high frequency of periodontitis, obesity, and overweight in the studied population but no association between obesity and periodontitis in pregnant women was found.
Background Periodontitis, an inflammatory disease of multibacterial etiology that affects the protective and supporting tissues surrounding teeth, can influence the course of respiratory diseases, such as asthma, due to epithelial alterations arising from inflammatory and immunological processes, bronchial remodeling, or by the aspiration of pathogenic colonizers found in periodontal pockets. This study evaluated the levels of periodontal pathogens Prevotella intermedia, Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, and Aggregatibacter actinomycetemcomitans in the subgingival biofilm of individuals with and without severe asthma. Methods A case‐control study enrolling 457 individuals (220 with asthma and 237 without asthma) was conducted at the Program for Control of Asthma in Bahia (ProAR) Clinic located in Salvador, Bahia, Brazil. A structured questionnaire was used to obtain data on sociodemographic, health status, and lifestyle habits. A clinical periodontal assessment was performed, including bleeding on probing, probing depth, and clinical attachment level. Subgingival biofilm was collected at the deepest site of each sextant, and bacterial DNA was extracted. Quantitative real‐time PCR analysis was performed to detect and relatively quantify periodontopathogens in the biofilm. Results Statistically significant positive associations were found between periodontitis and severe asthma, (odds ratio [OR]adjusted]: 4.00; 95% confidence interval [CI]: 2.26 to 7.10). High levels of P. intermedia were found in association with the presence of severe asthma (ORadjusted: 2.64; 95% CI: 1.62 to 4.39; P < 0.01). Conclusions The present results suggest that periodontitis and P. intermedia are associated with severe asthma. However, the functional consequences of this dysbiosis upon asthma susceptibility and its phenotypes remain unclear.
Background: An association between periodontitis and cardiovascular disease is now well documented; however, the effect of periodontitis severity levels on this outcome, specifically on acute myocardial infarction (AMI), remains unexplored. This study investigated the association between levels of periodontitis severity (exposure) and AMI (outcome). Methods: This case-control study, matched by sex and age, was conducted with 621 participants, with 207 individuals treated in the emergency department of Santa Izabel and Ana Nery Hospitals in Salvador, Bahia, Brazil, diagnosed with a first AMI event, and compared to 414 individuals without a diagnosis of AMI. Levels of periodontitis severity followed two criteria: (1) Center for Disease Prevention and Control and American Academy of Periodontology; (2) Gomes-Filho et al. (2018) using criteria that also evaluated bleeding upon probing. Conditional logistic regression analysis was performed and odds ratios (ORs) and their 95% confidence intervals (CIs) were obtained. Results: The adjusted association measurements showed a positive association between both severe (OR adjusted ranged from 2.21 to 3.92; 95% CI ranged from 1.03 to 10.05) and moderate periodontitis (OR adjusted ranged from 1.96 to 2.51; 95% CI ranged from 1.02 to 6.19), and AMI, for both periodontitis diagnostic criteria. It demonstrated that among those with moderate and severe periodontitis, the chance of 1444
Pooled data analysis in the field of maternal and child nutrition rarely incorporates data from low- and middle-income countries and existing studies lack a description of the methods used to harmonize the data and to assess heterogeneity. We describe the creation of the Brazilian Maternal and Child Nutrition Consortium dataset, from multiple pooled longitudinal studies, having gestational weight gain (GWG) as an example. Investigators of the eligible studies published from 1990 to 2018 were invited to participate. We conducted consistency analysis, identified outliers, and assessed heterogeneity for GWG. Outliers identification considered the longitudinal nature of the data. Heterogeneity was performed adjusting multilevel models. We identified 68 studies and invited 59 for this initiative. Data from 29 studies were received, 21 were retained for analysis, resulting in a final sample of 17,344 women with 72,616 weight measurements. Fewer than 1% of all weight measurements were flagged as outliers. Women with pre-pregnancy obesity had lower values for GWG throughout pregnancy. GWG, birth length and weight were similar across the studies and remarkably similar to a Brazilian nationwide study. Pooled data analyses can increase the potential of addressing important questions regarding maternal and child health, especially in countries where research investment is limited.
