raking method presented higher accuracy of the estimates when compared to cell-by-cell weighting method, proving to be most convenient, although it presents register coverage bias.

This study aimed to evaluate access to and utilization of various types of dental services by individuals 18 years or older in Brazil's State capitals. We gathered data from the Telephone Survey Surveillance System for Risk and Protective Factors for Chronic Diseases (VIGITEL) in 2009 (n = 54,367). More than half of the target population reported the need for dental treatment in the previous year; of these, 15.2% lacked access to dental services when needed. The private sector provided 61.1% of all dental appointments. The share of services provided by the Unified National Health System (SUS) ranged from 6.2% in the Federal District to 35.2% in Boa Vista, in the North. Multivariate Poisson regression models showed higher prevalence of dental treatment needs among women, middle-aged adults, and individuals with more schooling. Lack of access to dental care was more frequent among women, young adults, less educated individuals, and among lightener-skinned blacks. Our findings highlight sharp inequalities in the use of and access to dental services in the Brazilian State capitals.

Objective: to describe the most frequent signs and symptoms of infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods: this is a narrative literature review carried out in April 2020; the search was performed on electronic databases and complemented with a manual review of the references of the selected papers and Brazilian Ministry of Health publications. Results: the spectrum of clinical disease was wide; fever, coughing and dyspnea were the most frequent signs/ symptoms, however, they may not be present, thus hindering case definition; gastrointestinal symptoms and loss of taste or smell have been reported among mild cases; dyspnea was frequent among severe and fatal cases. Conclusion: considering the scarcity of diagnostic tests and the diversity of symptoms, health services should use a sensitive case definition, in order to adopt appropriate surveillance, prevention and treatment actions.

OBJECTIVES To analyze the factors associated with self-reported diabetes among adult participants of the National Health Survey (PNS).METHODS Cross-sectional study using data of the PNS carried out in 2013, from interviews with adults (≥ 18 years) of 64,348 Brazilian households. The prevalence of self-reported diabetes, assessed by the question “Has a doctor ever told you that you have diabetes?,” was related to sociodemographic characteristics, lifestyle, self-reported chronic disease, and self-evaluation of the health condition. Prevalence ratios were adjusted according to age, sex, and schooling by Poisson regression with robust variance.RESULTS The diagnosis of diabetes was reported by 6.2% of respondents. Its crude prevalence was higher in women (7.0% vs. 5.4%), and among older adults, reaching 19.8% in the elderly. Black adults who received less schooling showed higher prevalence. Among those classified as obese, 11.8% reported having diabetes. Ex-smokers, those insufficiently active and those who consume alcohol abusively reported diabetes more often. Differences were not verified in eating habits among adults who reported, or did not, diabetes. A relation between diabetes and hypertension was found.CONCLUSIONS After adjustment according to age, schooling and sex, diabetes was shown to be associated with higher age, lower schooling, past smoking, overweight and obesity, and hypertension, as well as with a self-declared poor state of health, indicating a pattern of risk factors common to many chronic non-communicable diseases and the association of the disease with morbidity.
