Translation and adaptation of the indoor environmental quality questionnaire to Brazilian portuguese

Introduction: Indoor environmental quality (IEQ) impacts well-being, performance, and mental and physical health. A questionnaire for assessing occupants' perception of IEQ was developed in English. This study aimed to translate this instrument into Brazilian Portuguese and adapt it to the Brazilian population.Methods: The translation and adaptation process consisted of forward translation, reconciliation, back translation, back translation review, harmonization, two cognitive debriefings, and finalization.Results: The final translated version included new questions and changed the scale to a visual-analog format. The clarity assessment showed that, after cognitive debriefings, all questions displayed satisfactory scores, with the majority rated higher than 9 on a 0-10 scale.Conclusions: The Brazilian Portuguese version of the IEQ questionnaire is a simple tool that can be employed in biomedical and building research to investigate the association of perceived IEQ with health-related parameters, as well as in architecture, engineering, and management projects. As a next step, a psychometric validation of the instrument will be performed.

Effect of professional certification on employees' return-to-work rate after occupational injuries in Korea: focusing on vulnerable groups

BACKGROUND@#One effective way to improve return-to-work (RTW) performance may be to convince the employer that the worker has the necessary skills. The aim of this paper is to investigate the effect of having a professional certification among workers injured in occupational injuries on their return to work.@*METHODS@#The Panel Study of Workers' Compensation Insurance (PSWCI) targets workers who completed medical care in 2012 after an occupational injury. The study population (n = 2000) was stratified by gender, age, region, disability grade, and rehabilitation service use. A total of 1458 workers were finally selected for this study. The effect of having a certification on RTW status was calculated with an odds ratio and 95% confidence intervals using binomial and multinomial logistic regression analyses. In the binomial logistic regression analysis, the RTW group was made up as a combination of the return to original work and the reemployment groups.@*RESULTS@#The ORs of RTW among those with a certification compared to those without certification were 1.38 (1.16-1.65) in Model 1, 1.25 (1.05-1.50) in Model 2, and 1.22 (1.01-1.47) in Model 3. Among female workers with a certification, the OR of RTW was 4.60 (2.68-7.91), that of return to original work was 3.21 (1.74-5.91), and that of reemployment was 5.85 (3.34-10.27). Among daily workers with a certification, the OR of RTW was 1.32 (1.03-1.69) and that of reemployment was 1.37 (1.07-1.76).@*CONCLUSION@#In conclusion, injured workers with a certification generally had a higher RTW rate. In particular, the RTW rate was higher among female workers and daily workers with a certification than among those without.

Industry and workplace characteristics associated with the downloading of a COVID-19 contact tracing app in Japan: a nation-wide cross-sectional study

BACKGROUND@#To combat coronavirus disease 2019 (COVID-19), many countries have used contact tracing apps, including Japan's voluntary-use contact-confirming application (COCOA). The current study aimed to identify industry and workplace characteristics associated with the downloading of this COVID-19 contact tracing app.@*METHODS@#This cross-sectional study of full-time workers used an online survey. Multiple logistic regression analysis was used to evaluate the associations of industry and workplace characteristics with contact tracing app use.@*RESULTS@#Of the 27,036 participants, 25.1% had downloaded the COCOA. Workers in the public service (adjusted odds ratio [aOR] = 1.29, 95% confidence interval [CI] 1.14-1.45) and information technology (aOR = 1.38, 95% CI 1.20-1.58) industries were more likely to use the app than were those in the manufacturing industry. In contrast, app usage was less common among workers in the retail and wholesale (aOR = 0.87, 95% CI 0.76-0.99) and food/beverage (aOR = 0.81, 95% CI 0.70-0.94) industries, but further adjustment for company size attenuated these associations. Workers at larger companies were more likely to use the app. Compared with permanent employees, the odds of using the app were higher for managers and civil servants but lower for those who were self-employed.@*CONCLUSIONS@#Downloading of COCOA among Japanese workers was insufficient; thus, the mitigating effect of COCOA on the COVID-19 pandemic is considered to be limited. One possible reason for the under-implementation of the contact tracing app in the retail and wholesale and food/beverage industries is small company size, as suggested by the fully adjusted model results. An awareness campaign should be conducted to promote the widespread use of the contact tracing app in these industries.

Profile of activities developed by community pharmacists: do they corroborate the precepts of the pharmaceutical profession?

Studies that addressed the profile of pharmaceutical activities and behaviors in community pharmacies in the last decades pointed to a gap between community pharmacy practice and the precepts of the profession. Facing the need to analyze whether the new legislation has impacted this scenario, the objective of this study was to describe the general profile and academic profile of community pharmacists, and the profile of the activities they develop, as well as to know their place of work. This is a descriptive study, to which all pharmacists in charge of community pharmacies in the metropolitan area of ​​Belo Horizonte-MG (n = 1624) were invited. Data collection was performed through a questionnaire validated online, from October to December 2017, via Google Docs®. Responses were obtained from 109 pharmacists, most of them female, aged 31-40 years, being general graduates, and in private institutions. Pharmacotherapeutic follow-up, an activity linked to clinical management, is performed by only 37.60% of pharmacists, evidencing that there is still a lag in relation to the provision of clinical services by community pharmacists. Thus, we emphasize the importance of implementing the precepts established by Brazilian curricular guidelines for undergraduate pharmacy courses which focus on the development of clinical skills, since the insertion of the pharmacist into the health team and the provision of clinical services to the community can add new value to the use of medications, and contribute effectively to their rational use in Brazil.

Low tetanus-diphtheria-acellular pertussis (Tdap) vaccine coverage among healthcare workers in a quaternary university hospital in São Paulo, Brazil: need for continuous surveillance and implementation of active strategies

Abstract Introduction: Vaccination with tetanus-diphtheria-acellular pertussis (Tdap) has been recommended for healthcare workers (HCWs) by Brazilian Ministry of Health since November 2014. Objective: To describe the strategies implemented to improve Tdap uptake, cumulative vaccine coverage after each intervention, variables associated to Tdap vaccination, and reasons for non-vaccination among HCWs of the main building of a quaternary hospital attached to the Sao Paulo University Medical School. Methods: A list of HCWs eligible for pertussis vaccination was generated. From April to December 2015, the following interventions were implemented: note on intern journal reminding the importance of pertussis vaccination; email to the head nurses strengthening vaccine recommendations; lectures on pertussis and Tdap for physicians of Obstetrics and Neonatology Clinics; on-site vaccination by mobile teams at the Obstetrics, Neonatology, and Anesthesiology Clinics. Vaccine coverage was accessed at the end of each month. Multivariate Poisson regression model with a robust error variance was used to evaluate variables associated with Tdap vaccination. Reasons for non-vaccination were evaluated from January to May 2017 through phone calls for HCWs who had not received Tdap. Results: The study included 456 HCWs. After the interventions, Tdap coverage raised from 2.8% to 41.2%. In the multivariate analysis, occupation (physician), working place (obstetrics or anesthesiology) and influenza vaccination in 2015 were independently associated to Tdap vaccination. The main reason for non-vaccination was unawareness of Tdap recommendations. Conclusions: Tdap uptake among HCWs was low in our hospital. Providing vaccination at convenient places/times for HCW seems to be the most efficient strategy to increase vaccine uptake.

Workers' perception of hazards on recycling sorting facilities in São Paulo, Brazil / Percepção dos trabalhadores quanto aos perigos em centrais de triagem de recicláveis em São Paulo, Brasil

Abstract The paper discusses views, perceptions, experiences, knowledge and behaviors related to occupational risks among recycling workers. Data collection involved field observation and two focus groups in each site. Narratives were recorded, transcribed, and analyzed for themes. Findings are presented according to the following topics: economic and environmental value of recycling; aspects of employment in the cooperative system; occupational hazards; and suggestions of improvements. Municipal programs of selective collection, as implemented in most Brazilian municipalities, still need improvements to achieve their goals and objectives. We learned that organizing recycling workers in cooperatives, despite its broad acceptance as a replacement to informal garbage collection in streets and landfills, only brought small progress regarding the safety and quality of life of cooperative workers. Recycling workers noticed the existence of workplace hazards, but seemed resigned to the situation, considered them as part of the job and did not communicate their needs to supervisors. They ignored the existence of some measures to prevent hazards and sometimes even created work practices and alternatives that endangered their own health.

Resumo O artigo discute pontos de vista, percepções, experiências, conhecimentos e comportamentos relacionados aos riscos ocupacionais entre os trabalhadores de reciclagem. Coleta de dados envolveu observação de campo e dois grupos focais em cada unidade. Narrativas foram gravadas, transcritas e analisadas por temas. Resultados são apresentados de acordo com os seguintes tópicos: valor econômico e ambiental da reciclagem; aspectos do sistema cooperativista; riscos ocupacionais e sugestões de melhorias. Programas municipais de coleta seletiva, tal como implantados na maioria dos municípios brasileiros, ainda precisam de melhorias para atingir suas metas e objetivos. Aprendemos que a organização de trabalhadores da reciclagem em cooperativas, apesar de sua ampla aceitação como um substituto para a coleta de lixo informal nas ruas e aterros, trouxe pouco progresso em relação à segurança e qualidade de vida dos cooperados. Os trabalhadores notaram a existência de riscos no local de trabalho, mas parecem resignados com a situação, consideram como parte do trabalho e não comunicam as suas necessidades aos supervisores. Eles ignoraram a existência de algumas medidas para evitar riscos e, por vezes, até criam práticas de trabalho e alternativas que colocam em perigo a própria saúde.

Nurse work environment: comparison between private and public hospitals / Ambiente de trabalho do enfermeiro: comparação entre hospitais privados e público

ABSTRACT Objective To compare the characteristics of the work environment that enable the professional practice of nurses in private and public organizations. Methods A quantitative, exploratory, cross-section study, carried out in four health organizations - one public and three private, with 188 registered nurses. Participants answered the Brazilian version of the Nursing Work Index − Revised, which aims to evaluate the presence of characteristics that favor the development of nursing activities through 15 items distributed into three subscales: autonomy, control over the practice setting and relationships with physicians. The measurement scale used is Likert, and lower scores represent better evaluation of the environment, i.e. , more favorable characteristics are present to assist the development of nursing activities. Results The means of the responses of participants of private hospitals were smaller in all subscales of the instrument, as compared to those from public hospitals. Conclusion The environment of private hospitals showed more favorable characteristics to the professional practice of registered nurses than the public hospital environment.

RESUMO Objetivo Comparar as características do ambiente de trabalho que favorecem a prática profissional do enfermeiro em instituições privadas e pública. Métodos Estudo quantitativo, exploratório, transversal, realizado em quatro instituições de saúde, sendo uma pública e três privadas, com 188 enfermeiros. Os participantes responderam a versão brasileira do Nursing Work Index − Revised , que tem por objetivo avaliar a presença de características que favorecem o desenvolvimento das atividades do enfermeiro por meio de 15 itens distribuídos em três subescalas: autonomia, controle sobre o ambiente de trabalho e relações entre médicos. A escala de medida utilizada é do tipo Likert e menores pontuações representam melhor avaliação do ambiente, ou seja, mais características favoráveis estão presentes para auxiliar o desenvolvimento das atividades da enfermagem. Resultados As médias das respostas dos participantes dos hospitais privados foram menores em todas as subescalas do instrumento, quando comparadas às do hospital público. Conclusão Os ambientes dos hospitais privados demonstraram possuir mais características favoráveis à prática profissional do enfermeiro do que o ambiente do hospital público.

Quality of the record of data on fatal workplace injuries in Brazil / Qualidade do registro de dados sobre acidentes de trabalho fatais no Brasil

ABSTRACT OBJECTIVE To evaluate the quality of the data on fatal workplace injuries in Brazil, in the Mortality Information System (SIM) and the Information System of Notifiable Diseases (SINAN-AT), analyzing the spatial and temporal distribution between 2007 and 2012. METHODS We identified fields related to fatal workplace injuries, which were examined for completeness and the use of the "ignored" option. From the SIM, we extracted the records of deaths from external causes, which require the completing of the <acidtrab> field about their relation with work. From the SINAN, we analyzed the <evolution> field, which allows us to identify fatal cases among s severe workplace injuries. RESULTS In the SIM, from 469,121 records, the <acidtrab> field was left unfilled or filled as ignored in 84.2% of them; the Brazilian region with the highest proportion was the Northeast (79.1%), from which the state of Alagoas (94.4%) had the highest amount. There was a 5.5% decreasing trend between 2007 (86.6%) and 2012 (81.8%). Among the 251,681 records found in the SINAN-AT, 28.3% had unfilled or ignored responses for <evolution>, varying from 39.7% in 2007 to 23.2% in 2012, a 41.6% decrease. CONCLUSIONS The quality of the records on the fields of interest needed to identify fatal workplace injuries is poor in the SIM, but gradually improving. Recording quality was better for SINAN-AT, which has also been strongly getting better lately.

RESUMO OBJETIVO Avaliar a qualidade do registro de dados sobre acidentes de trabalho fatais no Brasil nos Sistema de Informação sobre Mortalidade (SIM) e Sistema de Informação de Agravos de Notificação para acidentes de trabalho grave (Sinan-AT), analisando a distribuição espacial e temporal entre 2007 e 2012. MÉTODOS Identificaram -se os campos relacionados ao acidente de trabalho fatal, que foram examinados para a completude e uso da opção "ignorado". Do SIM, foram extraídos os registros de óbitos por causas externas, para os quais é requerido o preenchimento do campo <acidtrab>, sobre a relação com o trabalho. Do Sinan, analisou-se o campo <evolucao>, que permite a identificação dos casos fatais dentre os acidentes de trabalho graves. RESULTADOS No SIM, dos 469.121 registros, o campo <acidtrab> foi deixado sem preenchimento ou foi preenchido como ignorado em 84,2%, maior na região Nordeste (79,1%) e, em especial, no estado do Alagoas (94,4%). A tendência foi de queda de 5,5% entre 2007 (86,6%) e 2012 (81,8%). Para os 251.681 registros no Sinan-AT, a falta de preenchimento ou o uso de resposta ignorada no campo <evolucao> representaram, juntos, 28,3%, passando de 39,7% em 2007 para 23,2% em 2012, um declínio de 41,6%. CONCLUSÕES A qualidade do preenchimento de campos de interesse para o reconhecimento de casos de acidentes de trabalho fatais é ruim no SIM, mas vem gradualmente melhorando. No Sinan-AT, a qualidade dos registros foi melhor do que no SIM e vem melhorando acentuadamente.

Role of Emotional Intelligence in Conflict Management Strategies of Nurses

PURPOSE: This study analyzes the emotional intelligence levels and conflict management strategies of nurses and the association between them. METHODS: This cross-sectional, descriptive study was conducted with 277 nurses in a stratified random sample from a university hospital in Turkey. The data were collected from nurses who gave their informed consent to participate using a personal information form, the Rahim Organizational Conflict Inventory-II and Bar-On's Emotional Quotient Inventory (EQ-I). Data were assessed by descriptive statistics, t tests, and Pearson correlation analyses, using SPSS software. RESULTS: The levels of the nurses' strategies were as follows: avoiding (M = 2.98), dominating (M = 2.76), and obliging (M = 2.71) were medium; compromising (M = 1.99) and integration (M = 1.96) were low. The levels of the emotional intelligence of nurses (mean = 2.75) were medium on a 5-point scale. Integration (r = .168), obliging (r = .25), dominating (r = .18), and compromising (r = .33), which are conflict management strategies, were positively correlated with scores of emotional intelligence, and avoiding (r = −.25) was negatively correlated with scores of emotional intelligence (p < .05). CONCLUSIONS: The study determined that nurses' emotional intelligence affects conflict management strategies. To use effective strategies in conflict management, nurses must develop emotional intelligence. Training programs on conflict management and emotional intelligence are needed to improve effective conflict management in healthcare facilities.

The influence of the area of the Serra da Mesa Hydroelectric Plant, State of Goiás, on the frequency and diversity of anophelines (Diptera: Culicidae): a study on the effect of a reservoir

INTRODUCTION: Bioecological aspects of anophelines (Diptera: Culicidae) near areas under the direct influence of the hydroelectric plant reservoir of Serra da Mesa in Goiás, Brazil, were analyzed. METHODS: Samples were collected at the surrounding dam area during the phases before and after reservoir impoundment. The influence of climatic and environmental factors on the occurrence of Anopheles darlingi, Anopheles albitarsis, Anopheles triannulatus, Anopheles oswaldoi and Anopheles evansae was assessed using Pearson's correlations with indicators for richness and diversity as well as the index of species abundance (ISA) and the standardized index of species abundance (SISA). RESULTS: The highest anopheline density occurred during the phase after filling the tank; however, no direct correlation with the climatic factors was observed during this stage. The reservoir formation determined the incidence of the anopheline species. An. darlingi was the predominant species (SISA = 1.00). CONCLUSIONS: The significant difference (p < 0.05) observed between the species incidence during the different reservoir phases demonstrates the environmental effect of the reservoir on anophelines. .

Clase social, factores de riesgo psicosocial en el trabajo y su asociación con la salud autopercibida y mental en Chile / Social class, psychosocial occupational risk factors, and the association with self-rated health and mental health in Chile / Classe social, fatores psicossociais de risco ocupacional e sua associação com saúde autopercebida e mental no Chile

El objetivo fue examinar la relación entre clase social, riesgo psicosocial laboral y la salud autopercibida y mental en Chile. Se trata de un estudio transversal con los datos de la Primera Encuesta Nacional de Condiciones de Empleo, Trabajo, Calidad de Vida y Salud de los Trabajadores y Trabajadoras en Chile (N = 9.503). Las variables dependientes son: salud mental y salud autopercibida. Las variables explicativas son: clase social neo-marxista, factores de riesgo psicosocial y privación material. Se realizaron análisis descriptivos y de regresión logística. Existen desigualdades en la distribución de los factores exposición laboral a riesgos psicosociales, según clase social y sexo. Además, la clase social y los factores de riesgo psicosocial en el trabajo están asociados a una distribución desigual de la salud autopercibida y salud mental entre la población trabajadora en Chile. Las intervenciones en el área de la salud de los trabajadores deben considerar la clase social y los factores de riesgo psicosocial a que están expuestos los trabajadores.

The objective of this study was to analyze the association between social class and psychosocial occupational risk factors and self-rated health and mental health in a Chilean population. A cross-sectional study analyzed data from the First National Survey on Employment, Work, Quality of Life, and Male and Female Workers in Chile (N = 9,503). The dependent variables were self-rated health status and mental health. The independent variables were social class (neo-Marxist), psychosocial occupational risk factors, and material deprivation. Descriptive and logistic regression analyses were performed. There were inequalities in the distribution of psychosocial occupational risk factors by social class and sex. Furthermore, social class and psychosocial occupational risk factors were associated with unequal distribution of self-rated health and mental health among the working population in Chile. Occupational health interventions should consider workers’ exposure to socioeconomic and psychosocial risk factors.

O objetivo foi analisar a associação entre classe social, fatores psicossociais de risco laboral e saúde autopercebida e saúde mental entre a população trabalhadora chilena. Estudo transversal com os dados da Primera Encuesta Nacional de Condiciones de Empleo, Trabajo, Calidad de Vida y Salud de los trabajadores y trabajadoras en Chile (N = 9.503). As variáveis dependentes são: saúde autopercebida e saúde mental. As variáveis explicativas são a classe social (neo-marxista), os fatores psicossociais de risco laboral e privação material. Foram realizadas análises descritivas e de regressão logística. Existem desigualdades na distribuição dos fatores psicossociais de risco laboral segundo classe social e sexo. Além disso, a classe social e os fatores de risco psicossociais no trabalho estão associados a uma distribuição desigual da saúde autopercebida e saúde mental. As intervenções na área da saúde dos trabalhadores devem considerar a classe social e fatores de risco psicossociais a que os trabalhadores estão expostos.

Cross-cultural validity of the demand-control questionnaire: Swedish and Brazilian workers / Validade transcultural da escala demanda-controle: trabalhadores suecos e brasileiros

OBJECTIVE To evaluate the cross-cultural validity of the Demand-Control Questionnaire, comparing the original Swedish questionnaire with the Brazilian version. METHODS We compared data from 362 Swedish and 399 Brazilian health workers. Confirmatory and exploratory factor analyses were performed to test structural validity, using the robust weighted least squares mean and variance-adjusted (WLSMV) estimator. Construct validity, using hypotheses testing, was evaluated through the inspection of the mean score distribution of the scale dimensions according to sociodemographic and social support at work variables. RESULTS The confirmatory and exploratory factor analyses supported the instrument in three dimensions (for Swedish and Brazilians): psychological demands, skill discretion and decision authority. The best-fit model was achieved by including an error correlation between work fast and work intensely (psychological demands) and removing the item repetitive work (skill discretion). Hypotheses testing showed that workers with university degree had higher scores on skill discretion and decision authority and those with high levels of Social Support at Work had lower scores on psychological demands and higher scores on decision authority. CONCLUSIONS The results supported the equivalent dimensional structures across the two culturally different work contexts. Skill discretion and decision authority formed two distinct dimensions and the item repetitive work should be removed. .

OBJETIVO Avaliar a validade transcultural da escala demanda-controle, comparando o questionário original sueco com a versão brasileira. MÉTODOS Foram comparados os dados de trabalhadores de saúde, 362 suecos e 399 brasileiros. Foram utilizadas análise fatorial confirmatória e exploratória para avaliar a validade estrutural, usando o estimador robusto de mínimos quadrados ponderados ajustados para média e variância (WLSMV). A validade de construto via teste de hipóteses foi avaliada pela inspeção da distribuição dos escores médios das dimensões da escala segundo as características sociodemográficas e níveis de apoio social no trabalho. RESULTADOS A análise fatorial confirmatória e exploratória corroborou o instrumento em três dimensões (suecos e brasileiros): demandas psicológicas, uso de habilidades e autonomia para decisão. O modelo de melhor ajuste foi obtido após incluir uma correlação de resíduos entre os itens trabalho rápido e trabalho intenso (demandas psicológicas) e remover o item trabalho repetitivo (uso de habilidades). O teste de hipóteses mostrou que trabalhadores com nível universitário apresentaram maiores escores em uso de habilidades e autonomia para decisão e aqueles com grau elevado de apoio social no trabalho obtiveram escores menores em demandas psicológicas e maiores em autonomia para decisão. CONCLUSÕES Os resultados confirmaram a equivalência da estrutura dimensional em dois contextos laborais culturalmente diferentes. Uso de habilidades e autonomia para decisão formaram duas dimensões distintas e o item trabalho repetitivo deveria ser removido da escala. .

HIV risk practices by female sex workers according to workplace / Práticas de risco ao HIV de mulheres profissionais do sexo

OBJECTIVE To investigate differences in HIV infection- related risk practices by Female Sex Workers according to workplace and the effects of homophily on estimating HIV prevalence. METHODS Data from 2,523 women, recruited using Respondent-Driven Sampling, were used for the study carried out in 10 Brazilian cities in 2008-2009. The study included female sex workers aged 18 and over. The questionnaire was completed by the subjects and included questions on characteristics of professional activity, sexual practices, use of drugs, HIV testing, and access to health services. HIV quick tests were conducted. The participants were classified in two groups according to place of work: on the street or indoor venues, like nightclubs and saunas. To compare variable distributions by place of work, we used Chi-square homogeneity tests, taking into consideration unequal selection probabilities as well as the structure of dependence between observations. We tested the effect of homophily by workplace on estimated HIV prevalence. RESULTS The highest HIV risk practices were associated with: working on the streets, lower socioeconomic status, low regular smear test coverage, higher levels of crack use and higher levels of syphilis serological scars as well as higher prevalence of HIV infection. The effect of homophily was higher among sex workers in indoor venues. However, it did not affect the estimated prevalence of HIV, even after using a post-stratification by workplace procedure. CONCLUSIONS The findings suggest that strategies should focus on extending access to, and utilization of, health services. Prevention policies should be specifically aimed at street workers. Regarding the application of Respondent-Driven Sampling, the sample should be sufficient to estimate transition probabilities, as the network develops more quickly among sex workers in indoor venues. .

OBJETIVO Investigar diferenças nas práticas de risco à infecção pelo HIV segundo local de trabalho das mulheres profissionais do sexo e efeitos de homofilia na estimação da prevalência do HIV. MÉTODOS Foram utilizadas informações de 2.523 mulheres recrutadas por Respondent-Driven Sampling em estudo realizado em 10 cidades brasileiras, 2008-2009. Foram incluídas profissionais com 18 anos ou mais de idade. O questionário foi autopreenchido e incluiu perguntas sobre características da profissão, práticas sexuais, uso de drogas, testes periódicos de HIV e acesso aos serviços de saúde. Utilizaram-se testes rápidos para detecção de HIV. As participantes foram agregadas em dois grupos por local de trabalho: pontos de rua ou locais fechados, e.g., boates, saunas e termas. Foram utilizados testes Qui-quadrado de homogeneidade, levando-se em consideração as probabilidades desiguais de seleção, bem como a dependência entre as observações. Os efeitos de homofilia por local de trabalho foram pesquisados na estimação da prevalência do HIV. RESULTADOS As práticas de maior risco ao HIV associaram-se a: trabalhar em pontos de rua, menor nível socioeconômico, baixa cobertura de exame preventivo de câncer de colo de útero, elevado consumo de crack, maior prevalência de cicatriz sorológica de sífilis e maior prevalência de infecção pelo HIV. O efeito de homofilia foi maior entre as profissionais de locais fechados. Contudo, não afetou a estimativa da prevalência de HIV, mesmo utilizando o procedimento de pós-estratificação por local de trabalho. CONCLUSÕES Os resultados indicaram que as estratégias devem ser dirigidas à ampliação do acesso e à utilização dos serviços ...

El ambiente laboral como fuente de exposición a humo de tabaco ambiental: Estudio en trabajadores de bares y restaurantes de Santiago, Chile / The work environment as a source of exposure to secondhand smoke: a study in workers of bars and restaurants of Santiago, Chile

Background: Secondhand smoke (SHS) is an established cause of morbidity and mortality among non-smokers. The workplace is an important source of exposure, especially among workers of restaurants, bars and nightclubs. Aim: To estimate the daily occupational exposure to SHS among non-smoking workers of bars and restaurants of Santiago, Chile. Material and Methods: Environmental vapor-phase nico-tine was measured for 95 non-smoking workers of bars and restaurants of Santiago, using passive personal samplers during a daily work shift and outside the workplace. Results: The median occupational exposure to air nicotine was 9.18 µg/m³ (P25-P75 3.15-25.67 µg/m³). Higher concentrations were found among workers of places with no smoking restrictions (22.72 µg/m³; P25-P75 5.73-34.85 µg/m³), bar workers (20.75 µg/m³, P25-P75 5.03-44.67 µg/m³), waiters (20.57 µg/m³, PP25-P75 5.66-42.73 µg/m3) and bartenders (10.37 µg/m³, P25-P75 9.75-25.67 µg/m³). The median concentration of nicotine outside the workplace was 1.79 µg/m³ (P25-P75 1.02-3.00 µg/m³). Occupational exposure was 4.77 times higher compared to the non-work exposure. Conclusions: Workers of bars and restaurants are exposed to high levels of SHS at the workplace. Moreover, occupational exposure among these non-smoking workers is, in most cases, the main source of daily exposure to this pollutant.

Trabajo infantil y salud en un mercado público de Valencia, Venezuela / Child labor and health in a public market, Valencia, Venezuela

Objetivo Determinar condiciones de vida, prácticas de trabajo, efectos a la salud y factores de riesgo asociados en un grupo de menores trabajadores de un mercado público en Valencia, Venezuela. Metodología Se aplicó una encuesta con variables demográficas y de exposición y se realizó análisis descriptivo de los datos, seleccionándose 44 menores. Resultados La jornada de trabajo promedio fue de 9,2 ± 3,2 horas/día. La actividad más desempeñada fue la venta de víveres/frutos (43,2 por ciento). El 22,7 por ciento de los menores presentaba retraso escolar evidente. Los síntomas más reportados fueron cefalea (84 por ciento), estrés (59,1 por ciento) y fatiga (58,2 por ciento). El 11,4 por ciento reportaron haber sufrido accidentes y 2,3 por ciento enfermedad relacionados con la actividad presente. Los factores de riesgo más reportados fueron calor (93,2 por ciento), ruido (88,6 por ciento) y repetitividad en la labor (84,1 por ciento). Se encontró una correlación significativa, inversamente proporcional, entre la edad y el estrés (p=0,04) lo cual es consistente con estudios que indican que el impacto negativo del estrés es más profundo en niños que tienen menos de 10 años de edad. Se determinó significativamente que a menor edad hay una mayor exposición a desechos tóxicos orgánicos (p=0,017) y al trabajo bajo presión (p=0,04). Conclusiones No existen procesos de recolección sistemáticos para evaluar el trabajo infantil en nuestro país aún cuando se identificaron una amplia variedad de factores de riesgo percibidas por los niños trabajadores. Para una evaluación más profunda del problema, se requieren indicadores más sensibles que permitan detectar daños tempranos y la forma de controlar la exposición a los mencionados riesgos.

Objectives This study was aimed at determining the living conditions, work practices, health effects and associated occupational risk factors in children working in a public market in Valencia, Venezuela. MethodologyA questionnaire was administered which included demographic and exposure variables; a descriptive analysis was then made of the data. Forty-four children were selected. Results The average workday lasted 9.2 ± 3.2 hours/day. Children were most frequently employed in selling provisions and fruit (43.2 percent); 22.7 percent of them were evidently backward at school. The symptoms most reported were headache (84 percent), stress (59.1 percent) and fatigue (58.2 percent). Occupational accidents were reported by 11.4 percent of the children and 2.3 percent had suffered an occupational disease related to their present activity. The most frequently occurring occupational risks were discomfort caused by heat (93.2 percent), noise (88.6 percent) and repetitive work (84.1 percent). A significant, indirect correlation was found between age and stress (p=0.04), as in publications showing that the negative impact of stress is more severe in children aged less than 10. It was determined that being a minor had greater significant association with the occupational risk of having greater exposure to organic toxic waste (p=0.017) and working under pressure (p=0.04). Conclusions There is no systematic data collection programme for assessing child labour in Venezuela even though a variety of risk factors have been identified and perceived for children. More sensitive indicators are required for the early identification of effects and how to control exposure to the risks mentioned above so that the problem can be studied in greater depth.

Clima laboral en una escuela de medicina. Estudio de seguimiento / Work environment assessment at a medical school

Background: The work environment of an organization has to do with a set of permanent qualities that are experienced by its members. Aim: To assess the work environment perception of faculty members of a Medical School in two different periods (2005 and 2007). Material and methods: A standardized survey was applied to faculty members and Department chairs of the academic units of our Medical School. The survey used the Likert scale from 1 to 5 and included 59 items, distributed in 8 factors. Additionally, there were two groups of statements, indicating the priorities for the School and for the academic departments.

[Assessment of noise level and frequency analysis of equipments used in dental clinics at Mashhad School of Dentistry]

Instruments and equipments used in dentistry field produce sounds with wide spectrum, so dentists and other personnel are exposed to these sounds continuously. The purpose of this study was measuring the received noise level of personnel working in clinics of Mashhad dental school and frequency analysis of sounds at 20-20000 Hz frequency range. In this study, the noise level in operational dentistry, endodontics, prosthodontics, oral surgery, periodontics, pediatric dentistry and orthodontics of Mashhad dental school were assessed in 2004. Sound level measuring device and their establishment and set up were selected in which according to acquired data, the received noise level of dentist and average received noise level of personnel could be calculated. Equivalent noise level [L[Aeq]] measured surrounding central unit of each clinic, was less than 73.2 dB and noise level inside each clinic was less than 69.9dB. The dentists received noise level during work and presence at the studied clinics was measured to be 67.2-83.7 dB. The equivalent maximum noise level in all clinics was related to frequency band of 630 Hz and sounds of operational dentistry, endodontics and periodontics clinics had strong components in high frequency. According to permitted exposure noise level, the received noise level of dentists and personnel in studied clinics were not hazardous, but because of high frequency sounds, it is suggested to repeat the study with systems which can assess analysis of higher frequencies
