Item Acesso aberto (Open Access) Association between perceived racial discrimination and hypertension: findings from the ELSA-Brasil study(Escola Nacional de Saúde Pública Sergio Arouca, Fundação Oswaldo Cruz, 2018-03) NOBRE, Aline Araújo; GRIEP, Rosane Härter; GUIMARÃES, Joanna Miguez Nery; PEREIRA, Alexandre; CHOR, Dóra; MENDES, Patrícia Miranda; BARRETO, Sandhi Maria; JUVANHOL, Leidjaira Lopes“Pardos” and blacks in Brazil and blacks in the USA are at greater risk of developing arterial hypertension than whites, and the causes of this inequality are still little understood. Psychosocial and contextual factors, including racial discrimination, are indicated as conditions associated with this inequality. The aim of this study was to identify the association between perceived racial discrimination and hypertension. The study evaluated 14,012 workers from the ELSA-Brazil baseline population. Perceived discrimination was measured by the Lifetime Major Events Scale, adapted to Portuguese. Classification by race/color followed the categories proposed by Brazilian Institute of Geography and Statistics (IBGE). Hypertension was defined by standard criteria. The association between the compound variable - race/racial discrimination - and hypertension was estimated by Poisson regression with robust variance and stratified by the categories of body mass index (BMI) and sex. Choosing white women as the reference group, in the BMI < 25kg/m2 stratum, “pardo” women showed adjusted OR for arterial hypertension of 1.98 (95%CI: 1.17-3.36) and 1.3 (95%CI: 1.13-1.65), respectively, whether or not they experienced racial discrimination. For black women, ORs were 1.9 (95%CI: 1.42-2.62) and 1.72 (95%CI: 1.36-2.18), respectively, for the same categories. Among women with BMI > 25kg/m2 and men in any BMI category, no effect of racial discrimination was identified. Despite the differences in point estimates of prevalence of hypertension between “pardo” women who reported and those who did not report discrimination, our results are insufficient to assert that an association exists between racial discrimination and hypertension.Item Acesso aberto (Open Access) Fluoretação da água no Brasil: distribuição regional e acurácia das informações sobre vigilância em municípios com mais de 50 mil habitantes(Fundação Oswaldo Cruz, 2019-07) COSTA, Angelo Giuseppe Roncalli da; NORO, Luiz Roberto Augusto; CURY, Jaime Aparecido; ZILBOVICIUS, Celso; PINHEIRO, Helder Henrique Costa; ELY, Helenita Corrêa; FRAZÃO, PauloSanitation data for 2008 indicated that 74.4% of Brazilian municipalities (counties) with more than 50,000 inhabitants were receiving fluoridated water, but no criteria were adopted to validate the information. The study aimed to verify the accuracy of information on water fluoridation, using as the reference water surveillance data from municipalities with more than 50,000 inhabitants in 2008 and during 2010-2015. Data from different sources were used, comparing the information pertaining to the period. Water samples were collected, and fluoride concentration was obtained by the electrometric method. Verification was performed by comparing the data obtained from different sources. Data were compared for 601 (97.9%) municipalities. The proportion of municipalities that performed surveillance based on external control increased from 39.4% to 48.5%. There was a high rate of false positives and false negatives (15.1%) in the data for 2008. Municipal coverage was 70.2%, or 4.2 percentage points below the published estimate (74.4%) for 2008. Surveillance records were observed in 54.3% of the fluoridated municipalities whose population coverage reached at least 50% of the population receiving treated water. There was an important improvement in fluoridation surveillance data, despite a high percentage of false positives and negatives. There are still wide interregional differences in the surveillance of water fluoridation in this sample of Brazilian municipalities, raising important public health challenges.
