RESUMO
Traffic-related air pollution is being associated with hematologic cancer in young individuals. This study performed a spatial analysis of the hematologic cancer incidence and mortality among younger people, using a Bayesian approach, to associate with traffic density in the city of São Paulo, Brazil. Two databases were employed: incidence (2002-2011) and mortality (2002-2013). The relationships between the cases of hematologic cancer and the covariates - traffic density, the Municipal Human Development Index (MHDI), and population density - were evaluated using a Besag-York-Mollié ecological model with relative risks (RRs) estimates. Per 1-unit standard-deviation increase in traffic density, in the MHDI, and in population density, the RR for the incidence was 1.06 (95% CI: 0.97-1.14), 1.28 (95% CI: 1.16-1.42), and 1.01 (95% CI: 0.94-1.08), respectively. For mortality, no covariates were considered risk factors. Our findings suggest significant association between living in regions with better socioeconomic conditions, where traffic density is usually higher, and risk of hematologic cancer in younger people.

BACKGROUND: Multiple lines of evidence have associated exposure to ambient air pollution with an increased risk of respiratory malignancies. However, there is a dearth of evidence from low-middle income countries, including those within South America, where the social inequalities are more marked. OBJECTIVES: To quantify the association between exposures to traffic related air pollution and respiratory cancer incidence and mortality within São Paulo, Brazil. Further, we aim to investigate the role of socioeconomic status (SES) upon these outcomes. METHODS: Cancer incidence between 2002 and 2011 was derived from the population-based cancer registry. Mortality data (between 2002 and 2013) was derived from the Municipal Health Department. A traffic density database and an annual nitrogen dioxide (NO2) land use regression model were used as markers of exposure. Age-adjusted Binomial Negative Regression models were developed, stratifying by SES and gender. RESULTS: We observed an increased rate of respiratory cancer incidence and mortality in association with increased traffic density and NO2 concentrations, which was higher among those regions with the lowest SES. For cancer mortality and traffic exposure, those in the most deprived region, had an incidence rate ratio (IRR) of 2.19 (95% CI: 1.70, 2.82) when comparing the highest exposure centile (top 90%) to the lowest (lowest 25%). By contrast, in the least deprived area, the IRR for the same exposure contrast was.1.07 (95% CI: 0.95, 1.20). For NO2 in the most deprived regions, the IRR for cancer mortality in the highest exposed group was 1.44 (95% CI: 1.10, 1.88) while in the least deprived area, the IRR for the highest exposed group was 1.11 (95% CI: 1.01, 1.23). CONCLUSIONS: Traffic density and NO2 were associated with an increased rate of respiratory cancer incidence and mortality in São Paulo. Residents from poor regions may suffer more from the impact of traffic air pollution.

OBJECTIVE: To compare cancer mortality among workers exposed to gamma and X radiation and the general population of the city of São Paulo, as well as that of the subgroup monitored with those not monitored for gamma and X radiation in a work unit with ionizing radiation based in the city of São Paulo. METHODS: Between 2016 and 2021, a retrospective open cohort study was carried out with workers who were employed from 08/31/1956 to 12/31/2016 based on data collected at the company and in official institutions. Standardized mortality ratios (SMR) were calculated by sex, age and calendar period of cancers grouped according to type, risk factor and organ system in two analyses: in the external analysis, the mortality of the study population was compared with that of the general population of the city of São Paulo; In the internal analysis, the mortality of the monitored subgroup was compared with that of the subgroup not monitored for gamma and X radiation. RESULTS: The external mortality analysis showed SMR=0.224 (95%CI 0.208-0.240) and the healthy worker effect, while the internal mortality analysis showed SMR=0.685 (95%CI 0.618-0.758). CONCLUSION: This study showed lower cancer mortality among exposed workers when compared to mortality in the general population and the healthy worker effect. Among workers monitored for gamma and X radiation, cancer mortality was lower when compared to those not monitored.

This report describes a survey of microbiology laboratories (n = 467) serving Brazilian hospitals with ≥10 intensive care beds and/or involved in the government health care adverse event reporting system. Coordinators were interviewed and laboratories classified as follows: Level 0 (no minimal functioning conditions-85.4% of laboratories); Level 1 (minimal functioning conditions but inadequate execution of basic routine-6.7%); Level 2 (minimal functioning conditions and adequate execution of basic routine but no adequate procedures for quality control-5.8%); Level 3 (minimal functioning conditions, adequate execution of basic routine, and adequate procedures for quality control, but no direct communication with the infection control department-0.9%); Level 4 (minimal functioning conditions, adequate execution of basic routine, adequate procedures for quality control, and direct communication with infection control, but no available advanced resources-none); and Level 5 (minimal functioning conditions, adequate execution of basic routine, adequate procedures for quality control, direct communication with infection control, and available advanced resources-0.9%). Twelve laboratories did not perform Ziehl-Neelsen staining; 271 did not have safety cabinets; and >30% without safety cabinets had automated systems. Low quality was associated with serving hospitals not participating in government adverse-event program; private hospitals; nonteaching hospitals; and those outside state capitals. Results may reflect what occurs in many other countries where defining priorities is important due to limited resources.

OBJECTIVE: To estimate the prevalence of exposure to the SARS-CoV-2 virus among individuals living in restricted freedom. METHODS: A seroprevalence survey was carried out with the population of the female penitentiary of the Centro de Progressão Penitenciária (CPP) in Butantan (municipality of São Paulo), between June 24 and August 20, 2020. During this period, according to the Secretariat of Penitentiary Administration (SAP), the positivity of rapid tests among inmates ranged from 65% to 78%. The evaluation method used in the study was the "One Step COVID-19" rapid test (chromatography), from the company Wondfo, also using the RT-PCR method in symptomatic participants to confirm the viral condition. The study population consisted of 879 female inmates and 170 employees of the institution. RESULTS: The prevalence of total antibodies (IgG/IgM) against the SARS-CoV-2 virus in the total population of 1049 study participants was 6.1%; among the population of 879 inmates,a prevalence of 5.8% was observed, and among the institution's employees, 7.5%. CONCLUSIONS: The prevalence of covid-19 at the Butantan CPP was low, which is due to the implementation of simple prevention measures at the institution, such as the use of masks (with appropriate changes), emphasis on hygiene, hand washing and social distancing, in addition to other strategies, such as suspending inmates' visits from relatives and friends and cutting back on elective medical appointments and outside work.

School expansion, changes in the educational model and funding problems have profoundly changed teaching in Brazil, intensifying demands on teachers. Health problems such as burnout are common in the profession. We investigated teacher burnout and its association with occupational factors, including violence. Data were collected using in-depth interviews and two specific instruments (the Maslach Burnout Inventory and Spanish Burnout Inventory). Statistical analysis was performed using Stata, version 13.0. Ninety-three teachers referred to psychotherapy from public schools in different regions of the city of São Paulo participated in the study. Burnout was associated with 11 school setting variables, including having suffered violence in the school (p <0.001), discomfort with interpersonal contact at work (p <0.001) and noise (p <0.001). Sixty percent of the teachers with severe burnout had suffered violence at school in the last year. Both collective and occupational issues were associated with teacher burnout. Among these, interpersonal conflict and violence, which appears as a new and common problem, adversely affect the health of these professionals.
A expansão da rede escolar, as mudanças no modelo educacional e os problemas de financiamento mudaram profundamente o trabalho docente no Brasil, intensificando as exigências dirigidas aos profissionais. Problemas de saúde, como o esgotamento profissional, são comuns na categoria. Levantamos a exposição dos professores ao esgotamento profissional e analisamos sua potencial associação aos elementos do contexto ocupacional, inclusive a violência. Os dados foram coletados por meio de entrevistas em profundidade, com uso de dois instrumentos específicos (MBI e CESQT) e analisados estatisticamente com o Programa Stata, v.13.0. Participaram 93 professores da rede pública municipal de São Paulo com indicação de psicoterapia, das diversas regiões da cidade. O esgotamento foi associado ao sofrimento de agressão na escola (p<0,001), ao incômodo nos contatos interpessoais no trabalho (p<0,001) e ao ruído (p<0,001), entre outras 11 variáveis do contexto escolar. Entre os que apresentaram esgotamento grave, 60% haviam sofrido agressão na escola no último ano. Questões coletivas e ocupacionais se associaram ao esgotamento profissional entre os participantes. Entre elas, os conflitos interpessoais e o fenômeno da violência, que surge como elemento novo e frequente, impactam a saúde dos profissionais.

The objective of this paper was to assess bacteriological quality of drinking water in a peri-urban area located in the Metropolitan Region of São Paulo, Brazil. A total of 89 water samples were collected from community plastic tanks and 177 water samples from wells were collected bimonthly, from September 2007 to November 2008, for evaluating bacteriological parameters including: Escherichia coli, Enterococcus and heterotrophic plate count (HPC). Clostridium perfringens was investigated in a subsample (40 samples from community plastic tank and 40 from wells). E. coli was present in 5 (5.6%) samples from community plastic tanks (2.0 - 5.1x10(4) MPN/100mL) and in 70 (39.5%) well samples (2.0 - 8.6x10(4) MPN/100mL). Thus, these samples were not in accordance with the Brazilian Regulation. Enterococcus was detected in 20 (22.5%) samples of the community plastic tanks (1 to 79 NC/100mL) and in 142 (80.2%) well samples (1 to >200 NC/100mL). C. perfringens was detected in 5 (12.5%) community plastic tanks samples and in 35 (87.5%) wells samples (2.2 to >16 MPN/100mL). HPC were above 500 CFU/mL in 5 (5.6%) waters from community plastic tanks. In wells samples, the HPC ranged from <1 to 1.6x10(4) CFU/mL. The residual chlorine did not attend the standard established in the drinking water legislation (0.2 mg/L), except in 20 (22.5%) samples. These results confirm the vulnerability of the water supply systems in this peri-urban area what is clearly a public health concern.
RESUMO
Hepatitis A virus (HAV) infection has been considered one of the leading causes of acute hepatitis. The aim of the present study was to estimate the prevalence of HAV among children and adolescents in a population-based study in the capitals of the States of the North, Southeast and South of Brazil and identify predictive factors for the infection. A multi-stage sampling was used to select subjects aged between 5-9 and 10-19 years. Individual and household levels aside from the level of variables in the areas were collected. The outcome was the total IgG antibodies to HAV levels detected using a commercial Enzyme Immuno Assay (EIA). The associations between HAV and the independent variables were assessed using the odds ratio. A multilevel analysis was performed by GLLAMM using the Stata software. The prevalence of HAV infection in the 5-9 and 10-19 age groups was 28.7% and 67.5%, respectively for the North, 20.6% and 37.7%, for the Southeast and 18.9% and 34.5% for the South Region. The prevalence of HAV increased according to age in all sites. Variables related to education at the individual level (North and South), family and area level (South and Southeast) and family income level (Southeast and South) were independently associated with HAV infection. This emphasizes the need for individualized strategies to prevent the infection.

BACKGROUND: Despite widespread evidence that air pollution is carcinogenic, there is little evidence from low-middle income countries, especially related to childhood malignancies. We examined the role of traffic related pollution on lymphohematopoietic malignancies among under-14 s in Sao Paulo. METHODS: All incident cases between 2002 and 2011 were collected from a population-based registry. Exposures were assigned on residential address at diagnosis via traffic density database (for the year 2008) and a satellite derived NO2 land use regression model (averaged between 1997 and 2011). Incidence rate ratios (IRRs) were calculated via Poisson Regression adjusted by age, gender and socioeconomic status (SES), with additional stratification by SES. RESULTS: A positive association between traffic and NO2 with some lymphohematopoietic malignancies was observed with the degree of effect differing by SES. For example, lymphoid leukemia IRRs in the lower SES group were 1.21 (95 % CI: 1.06, 1.39) for traffic density and 1.38 (95 % CI: 1.13, 1.68) for NO2. In the higher group they were 1.06 (95 % CI: 1.00, 1.14) and 1.37 (95 % CI: 1.16, 1.62). CONCLUSION: NO2 and traffic density were associated with Hodgkin lymphoma and lymphoid leukemia among children in São Paulo. Differing IRRs by gender and SES group indicate differences in underlying risk and/or exposure profiles.

OBJECTIVE: To describe the methodological aspects of the Piauí home healthcare survey (ISAD-PI) and assess the relation between sampling plan, precision, and design effects, assuming that population health surveys are relevant instruments for health monitoring. METHODS: ISAD-PI was a population-based cross-sectional study that analyzed the living conditions and health status of the population residing in urban areas in the municipalities of Teresina and Picos, in Piauí. Sampling was carried out by conglomerates in two stages: Primary Sampling Units and households. To calculate the sample size, we considered the stratification of the population in both cities, according to the age of the individuals. We evaluated the "non-response" rate (NRR) and estimated the proportions according to sex and age, as well as the prevalence of social determinants of health in order to assess the compliance of the sampling plan. Analyses related to the precision according to the coefficient of proportion variation of the standard error (Cv-pË) and the design effect (deff). Cv-pË less than 20% and deff less than 1.5 were considered adequate. The total NRR of households was 38.2% in Teresina and 38.3% in Picos. We carried out twenty-four proportion estimates in relation to age and sex and 48 prevalence of social and health determinants estimates, totaling 72 estimates. Among them, 71 had Cv-pË less than 20% and 61 had deff less than or equal to 1.5. CONCLUSION: Data generated from the ISAD-PI may contribute to the assessment of health and morbidity conditions in the population. Furthermore, methodological aspects employed in this research may serve as a basis for studies carried out in other cities in Brazil.

The aim of this study was to estimate the indoor and outdoor concentrations of fungal spores in the Metropolitan Area of Sao Paulo (MASP), collected at different sites in winter/spring and summer seasons. The techniques adopted included cultivation (samples collected with impactors) and microscopic enumeration (samples collected with impingers). The overall results showed total concentrations of fungal spores as high as 36,000 per cubic meter, with a large proportion of non culturable spores (around 91% of the total). Penicillium sp. and Aspergillus sp. were the dominant species both indoors and outdoors, in all seasons tested, occurring in more than 30% of homes at very high concentrations of culturable airborne fungi [colony forming units(CFU) m(-3)]. There was no significant difference between indoor and outdoor concentrations. The total fungal spore concentration found in winter was 19% higher than that in summer. Heat and humidity were the main factors affecting fungal growth; however, a non-linear response to these factors was found. Thus, temperatures below 16 degrees C and above 25 degrees C caused a reduction in the concentration (CFU m(-3)) of airborne fungi, which fits with MASP climatalogy. The same pattern was observed for humidity, although not as clearly as with temperature given the usual high relative humidity (above 70%) in the study area. These results are relevant for public health interventions that aim to reduce respiratory morbidity among susceptible populations.

BACKGROUND: Most of the available data on invasive pneumococcal disease in Latin America are derived from laboratory-based surveillance systems. There is a lack of epidemiological data on the disease severity and mortality from hospitalized patients with pneumococcal infection. METHODS: In this hospital-based retrospective historical series of hospitalized children with laboratory-confirmed IPD, we evaluated changes in disease episodes, in-hospital fatality rates, and need for intensive care unit admission after the inclusion of PCV10 in the Brazilian vaccination schedule. Invasive pneumococcal strains isolated by culture were serotyped. Changes over time were assessed, and pre-vaccination (2005-2009) to post-vaccination (2011-2015) disease rates and serotypes were compared. RESULTS: 260 patients with IPD and positive pneumococcal isolates were identified (198 during the pre-PCV10 period). When comparing both periods, hospitalizations were reduced from 20 cases to 5 cases per 10,000 pediatric admissions (p < 0.0001). Likewise, fatalities reduced from 6.6 to 2.0 cases per 10,000 pediatric admissions (p < 0.0001). Pneumonia was the most frequent clinical diagnosis (58%) - of which 49.6% had pleural effusion - followed by meningitis (22%) and bacteremia (15.9%). Overall 30% of cases were sent to ICU, with no percentual changes after PCV10. Additional PCV13 serotypes increased from 7% before vaccine introduction to 21% after PCV10 use. Similarly, serotypes not included in PCV13 increased from 11% to 29%. CONCLUSIONS: There was a significant reduction in the hospitalizations rates, ICU admissions, and fatalities due to IPD after PCV10 introduction in Brazil. Cases due to PCV10 serotypes were reduced, while infections rates caused by non-PCV10 serotypes increased.

OBJECTIVE: Hot flashes have a negative impact on the quality of life of women during the menopausal transition and thereafter. The progressive reduction in gonadal estrogen levels associated with aging promotes an accumulation of abdominal fat, dyslipidemia, and arterial hypertension, all of which are components of metabolic syndrome (MetS). The objective of the present study was to estimate the prevalence of hot flashes and evaluate their relationship with MetS in women ≥ 40 years of age. METHODS: This was a cross-sectional study involving women aged between 40 and 65 years. We used the Kupperman index to quantify the climacteric symptoms and the National Cholesterol Education Program Adult Treatment Panel III criteria for the diagnosis of MetS. RESULTS: 1,435 women were initially selected, and we obtained information from 647. The mean age at menopause was 45.99 years (SD 6.61 years) and the prevalence of hot flashes and MetS were 55.83% (95% CI: 52.35-59.25%) and 46.29% (95% CI: 44.75-52.53%), respectively. We identified a positive association between MetS and hot flashes (OR 1.16; 95% CI: 1.01-1.33). CONCLUSIONS: In women ≥ 40 years of age, hot flashes are highly prevalent and appear to be associated with MetS.

OBJECTIVE To estimate the trends of fall-related hospitalization, mortality, and lethality among older adults in Brazil and regions. METHODS This is a descriptive study based on data from the Hospital Information System of the Brazilian Unified Health System. We included records of every older adult, aged 60 years or older, hospitalized for accidental fall from January, 1998 to November, 2015 in all Brazilian regions. We selected the codes E885, E886, E880, E884, E884 from the International Classification of Diseases, 9th revision, and W01, W03, W10, W17, W18 from the 10th revision, and calculated fall-related hospitalization and mortality rates per 100,000 inhabitants, as well as lethality. To estimate trends, we applied the Prais-Winsten regression for time series analysis. RESULTS During the period, 1,192,829 fall-related hospitalizations occurred, among which 54,673 had a fatal outcome; lethality was 4.5%. Hospitalization rates showed upward trends, with seasonality, in Brazil (11%), and in the Northeast (44%), Midwest (13%), and South regions (14%). The North showed a decreasing hospitalization rate (48%), and the Southeast a stationary one (3%). CONCLUSIONS In Brazil, fall-related hospitalizations, mortality, and lethality among older adults showed an upward trend from 1998 to 2015, with seasonal peaks in the second and third quarters. Considering we are in plain demographic transition, to improve hospital healthcare and encourage falls prevention programs among older adults is essential.

OBJECTIVE: To describe mortality due to hepatitis B and C as underlying cause in the municipality of São Paulo, verifying the trend of these rates, and to assess the association of these diseases with others, from 2002 to 2016. METHODS: This is a time series study on mortality due to hepatitis B and C according to sex, with data from the Sistema de Informação de Mortalidade (SIM - Mortality Information Sistem). Prais Winsten regression was used in rate trend analysis. RESULTS: The findings of this study showed a trend of decline of mortality from hepatitis B and C in recent years, particularly among males. These infections were important associated causes of liver cell carcinoma and HIV. The proportion of deaths under 70 years of age stands out. CONCLUSIONS: The study provides a baseline for research on mortality trend and the impact of interventions, given the history of expanded detection and supply of treatments, including the most recent antivirals in Brazil, since 2015.

In the context of megacities in an urban environment, air quality is an important issue, due to the direct correlation to population's health. The biomonitoring of pollutants can indicate subtle environmental alterations, for that, anemophilous fungi can be monitored for changes in atmospheric conditions related to pollution. In the present study, the concentration of fungi and bacteria in the atmosphere was measured during a specific vehicle fleet reduction in the city of São Paulo, Brazil, from May 24 to 30, 2018, using impactor air samplers. The number of isolated developed colonies was related to atmospheric conditions and the concentration of other air pollutants constantly monitored. Aspergillus, Curvularia, Penicillium, Neurospora, Rhizopus and Trichoderma were identified. The number of colony-forming units increased by approximately 80% during the sampling period in response to environmental changes favored by the fleet reduction. This result implies the relation between fuel emissions, concentration of atmospheric pollutants, and the presence of viable fungal spores in the urban environment, which highlights the importance of combined public policies for air quality in large cities.
RESUMO
OBJECTIVE: To estimate the prevalence of accidental falls in women and to identify possible associations of sociodemographic, clinical and lifestyle variables with falls, in 2007 and 2014. METHODS: Two cross-sectional studies were performed, in 2007 and 2014, within the Projeto de Saúde de Pindamonhangaba (PROSAPIN - Pindamonhangaba Health Project), with women aged between 35 to 75 years. Probabilistic samples were selected among women living in the municipality and participating in the Health Family Strategy. Data collection included: face-to-face interview, anthropometric examination and blood test. The outcome variable "have you fallen in the last six months?" was raised during the interview. The prevalence of falls in 2007 and 2014 were estimated by score with a 95% confidence interval (95%CI). Multiple logistic regression models were constructed to identify the association of independent variables with the occurrence of falls for each year based on the odds ratio (OR). We used the Stata 14.0 software for statistical analysis. RESULTS: The prevalence of accidental falls were: 17.6% (95%CI 14.9-20.5) in 2007 and 17.2% (95%CI 14.8-19.8) in 2014. In 2007, factors associated with falls were: aged 50-64 years (OR = 1.81; 95%CI 1.17-2.80), high school (OR = 1.76; 95%CI 1.06-2.93), hyperuricemia (OR = 3.74; 95%CI 2.17-6.44), depression (OR = 2.07; 95%CI 1.31-3.27), poor sleep (OR = 1.78; 95%CI 1.12-2.82) and daytime sleepiness (OR = 1.86; 95%CI 1.16-2.99). In 2014, they were: aged 50-64 years (OR = 1.64; 95%CI 1.04-2.58), hyperuricemia (OR = 1.91; 95%CI 1.07-3.43) and depression (OR = 1.56; 95%CI 1.02-2.38), plus metabolic syndrome (OR = 1.60; 95%CI 1.03-2.47) and musculoskeletal pain (OR = 1.81; 95%CI 1.03-3.18). CONCLUSIONS: Falls occur significantly in women aged 50 years or over, indicating that they are not restricted to older adults and that there is a need to initiate preventive measures earlier. Both studies showed similar magnitudes of occurrence of accidental falls and reinforced their multifactorial nature. In addition, hyperuricemia may be a potential new factor associated with falls.

ABSTRACT Objective: To compare cancer mortality among workers exposed to gamma and X radiation and the general population of the city of São Paulo, as well as that of the subgroup monitored with those not monitored for gamma and X radiation in a work unit with ionizing radiation based in the city of São Paulo. Methods: Between 2016 and 2021, a retrospective open cohort study was carried out with workers who were employed from 08/31/1956 to 12/31/2016 based on data collected at the company and in official institutions. Standardized mortality ratios (SMR) were calculated by sex, age and calendar period of cancers grouped according to type, risk factor and organ system in two analyses: in the external analysis, the mortality of the study population was compared with that of the general population of the city of São Paulo; In the internal analysis, the mortality of the monitored subgroup was compared with that of the subgroup not monitored for gamma and X radiation. Results: The external mortality analysis showed SMR=0.224 (95%CI 0.208-0.240) and the healthy worker effect, while the internal mortality analysis showed SMR=0.685 (95%CI 0.618-0.758). Conclusion: This study showed lower cancer mortality among exposed workers when compared to mortality in the general population and the healthy worker effect. Among workers monitored for gamma and X radiation, cancer mortality was lower when compared to those not monitored.
RESUMO Objetivo: Comparar a mortalidade por câncer entre trabalhadores expostos à radiação gama e X e a população geral do município de São Paulo, bem como a do subgrupo monitorado com o não monitorado para radiação gama e X em uma unidade de trabalho sediada no município de São Paulo. Métodos: Entre 2016 e 2021 foi realizado estudo de coorte aberta retrospectiva com trabalhadores que tiveram vínculo empregatício desde 31/08/1956 até 31/12/2016 a partir de dados coletados na empresa e em instituições oficiais. Foram calculadas as razões de mortalidade padronizadas (RMP) por sexo, idade e período calendário de cânceres agrupados segundo o tipo, o fator de risco e o sistema orgânico em duas análises: na análise externa, comparou-se a mortalidade da população de estudo com a da população geral do município de São Paulo; já na análise interna, comparou-se a mortalidade do subgrupo monitorado com a do subgrupo não monitorado para radiação gama e X. Resultados: A análise externa de mortalidade mostrou RMP=0,224 (IC95% 0,208-0,240) e o efeito do trabalhador sadio, enquanto a análise interna de mortalidade mostrou RMP = 0,685 (IC95% 0,618-0,758). Conclusão: Este estudo mostrou menor mortalidade por câncer entre os trabalhadores expostos quando comparada com a mortalidade da população geral e o efeito do trabalhador sadio. Entre os trabalhadores monitorados para radiação gama e X, a mortalidade por câncer foi menor quando comparada com a dos não monitorados.
RESUMO
BACKGROUND: One of the major environmental problems of the modern world is noise. A health-related marker of environmental noise exposure that can be considered a predictor of annoyance is noise sensitivity. The aim of this study was to ascertain the correlation between levels of exposure to road traffic noise in residential areas and the resulting annoyance based on the perception and sensitivity reported. METHODS: The study involved noise assessment, with the creation of noise maps of the neighborhood in the city of São Paulo, Brazil, and application of a questionnaire to ascertain the perception of the residents of the neighborhood, regarding the effects of this exposure. RESULTS: The noise levels at all the measured points were found to exceed the critical level for the area, 55â¯dB(A). A total of 225 interviews were conducted. Noise-related annoyance was reported by 48.4% of the respondents. Associations were observed between living in areas exposed to traffic noise and feeling annoyed with this noise (pâ¯<â¯0.001). CONCLUSIONS: These findings suggest the importance of reviewing and updating Brazilian public policies regarding environmental noise. We found a high prevalence of annoyance reports, as well as aspects indicative of sensitivity to noise exposure.

Pollution related to traffic is a major problem in urban centers and a large portion of the population is vulnerable to its health effects. This study sought to identify a potential association between hospital admissions due to respiratory tract cancer and vehicular traffic density in the city of São Paulo, Brazil. It is an ecological study of the public (Hospital Inpatient Authorization - AIH, in Portuguese) and private (Hospital Inpatient Communication - CIH, in Portuguese) health care systems, from 2004 to 2006, geocoded by individuals' residential addresses. Using a Besag-York-Mollié ecological model, we initially evaluated the relationship between number of cases of hospital admission due to respiratory tract cancer in each weighting area and the standardized co-variables: traffic density and Municipal Human Development Index (MHDI) as indicator of socioeconomic status. Using a classic Poisson model, we then evaluated the risk associated with growing traffic density categories. The Besag-York-Mollié model estimated a RR = 1.09 (95%CI: 1.02-1.15) and RR = 1.19 (95%CI: 1.10-1.29) of admission due to respiratory tract cancer for each increase of one standard deviation of traffic and MHDI, respectively. The Poisson model also showed a clear exposure-response gradient for admission due to respiratory tract cancer (IRR = 1.11; 95%CI: 1.07-1.15, for each 10 units of added traffic density). This study suggests that there is an association between residing in areas with high traffic density and hospital admissions due to respiratory tract cancer in the city of São Paulo.
A poluição relacionada ao tráfego é um grande problema nos centros urbanos, e uma grande parcela da população fica vulnerável aos seus efeitos à saúde. Este trabalho teve como objetivo identificar potencial associação entre as internações hospitalares por câncer do aparelho respiratório com a densidade de tráfego veicular no Município de São Paulo, Brasil. É um estudo ecológico com dados de internações hospitalares por câncer dos sistemas público (Autorização de Internação Hospitalar - AIH) e particular (Comunicação de Internação Hospitalar - CIH), de 2004 a 2006, geocodificados por endereço de residência do indivíduo. Mediante um modelo ecológico de Besag-York-Mollié foi avaliada inicialmente a relação entre o número de casos de internação por câncer do aparelho respiratório em cada área de ponderação e as covariáveis padronizadas: densidade de tráfego e Índice de Desenvolvimento Humano Municipal (IDHM) como indicador de status socioeconômico. Sequencialmente, com um modelo clássico de Poisson, procedeu-se uma avaliação do risco associado às categorias crescentes de densidade de tráfego. O modelo de Besag-York-Mollié estimou um RR = 1,09 (IC95%: 1,02-1,15) e RR = 1,19 (IC95%: 1,10-1,29) de internação por câncer do aparelho respiratório, para cada aumento de um desvio padrão da densidade de tráfego e IDHM, respectivamente. Foi também evidenciado pelo modelo de Poisson um claro gradiente de exposição-resposta para internação por câncer respiratório (IRR = 1,11; IC95%: 1,07-1,15, para cada dez unidades de acréscimo da densidade de tráfego). Este trabalho sugere que há associação entre residir em áreas com alta densidade de tráfego e internação por câncer do aparelho respiratório no Município de São Paulo.

Mediante el modelo ecológico de Besag-York-Mollié se evaluó inicialmente la relación entre el número de casos de internamiento por cáncer del aparato respiratorio en cada área de ponderación y covariables estandarizadas: densidad de tráfico e Índice de Desarrollo Humano Municipal (IDHM), como indicador de estatus socioeconómico. Secuencialmente, con un modelo clásico de Poisson, se procedió a una evaluación del riesgo asociado a las categorías crecientes de densidad de tráfico. El modelo de Besag-York-Mollié estimó un RR = 1,09 (IC95%: 1,02-1,15) y RR = 1,19 (IC95%: 1,10-1,29) de internamiento por cáncer del aparato respiratorio, para cada aumento de un desvío estándar de la densidad de tráfico e IDHM, respectivamente. Se evidenció también, a través del modelo de Poisson, un claro gradiente de exposición-respuesta para el internamiento por cáncer respiratorio (IRR = 1,11; IC95%: 1,07-1,15, para cada 10 unidades de incremento de la densidad de tráfico). Este trabajo sugiere que existe una asociación entre residir en áreas con alta densidad de tráfico y el internamiento por cáncer del aparato respiratorio en el Municipio de São Paulo.
