Qualidade de vida e saúde vocal de professores

OBJETIVO: Avaliar aspectos associados à qualidade de vida de professores e buscar relações com questões de saúde vocal. MÉTODOS: Foi estudada uma amostra de 128 professores de ensino médio de quatro escolas estaduais de Rio Claro, SP, em 2002. Foram aplicados os questionários World Health Organization Quality of Life/bref e Qualidade de Vida e Voz e calculados média e desvio-padrão para os escores do primeiro questionário e da questão de auto-avaliação vocal do questionário Qualidade de Vida e Voz. Utilizou-se o teste de Wilcoxon para comparar os gêneros; o de Kruskal-Wallis para as escolas; e o coeficiente de correlação de Spearman e teste t para verificar associação entre os domínios da qualidade de vida, a auto-avaliação vocal e idade, e número de períodos que o professor leciona. RESULTADOS: A maioria avaliou a voz como boa (42,2%) e o escore médio do questionário de avaliação de qualidade de vida foi 66, com maiores valores do domínio relações sociais e menores do meio ambiente. Os aspectos associados foram oportunidades de lazer, condições financeiras, ambiente de trabalho e acesso à informação. O número de períodos lecionados apresentou correlação positiva e significativa com a auto-avaliação vocal. Não houve diferença significativa entre os gêneros. Houve diferenças significativas no domínio físico, quando comparados os resultados das diferentes escolas. CONCLUSÕES: Apesar de razoavelmente satisfeitos com a voz e a qualidade de vida, os professores mostraram dificuldades na percepção do processo saúde-doença. Evidenciaram-se aspectos desfavorecidos da qualidade de vida e necessidades de saúde que podem ter implicações na voz e saúde vocal docente.

Validity of the Brazilian version of WHOQOL-BREF in depressed patients using Rasch modelling

OBJECTIVE: To assess the validity of the Brazilian version of the World Health Organization Quality of Life Instrument - Abbreviated version (WHOQOL-BREF) in adults with major depression, using Rasch modelling. METHODS: Study analyzing data from the baseline sample of the Longitudinal Investigation of Depression Outcomes in Brazil, including a total of 208 patients with major depression recruited in a primary care service in Porto Alegre (Southern Brazil), in 1999. The Center for Epidemiological Studies Depression Scale was used to assess intensity of depression; the WHOQOL-BREF to assess generic quality of life; and the Composite International Diagnostic Interview version 2.1 for the diagnosis of depression. RESULTS: In the Rasch analysis, the four domains of WHOQOL-BREF showed appropriate fit to this model. Some items needed adjustments: four items were rescored (pain, finances, services, and transport); two items (work and activity) were identified as having dependency of responses, and one item was deleted (sleep) due to multidimensionality. CONCLUSIONS: The validation of the WHOQOL-BREF Brazilian version using Rasch analysis complements previous validation studies, evidencing the robustness of this instrument as a generic cross-cultural quality of life measure.

Qualidade de vida de vítimas de trauma seis meses após a alta hospitalar

OBJETIVO: O trauma ocupa o terceiro lugar dentre as causas de morte no Brasil. Contudo, seu impacto na qualidade de vida dos sobreviventes tem sido pouco estudado no País. O objetivo do estudo foi avaliar a qualidade de vida de vítimas de trauma atendidas em unidade hospitalar de emergências, seis meses após a alta hospitalar. MÉTODOS: Foram incluídos 35 pacientes de unidade de emergência de hospital universitário de Ribeirão Preto (SP), entre 2005 e 2006. Os pacientes foram entrevistados em seus domicílios, seis meses após terem tido alta hospitalar. Foi aplicado o instrumento World Health Organization Quality of Life, versão breve, para avaliação dos domínios físico, psicológico, relações sociais e meio ambiente. As associações entre os escores dos domínios e as variáveis permanência hospitalar, idade, sexo e Injury Severity Score foram exploradas por modelos de regressão linear. RESULTADOS: Observou-se diminuição significativa na qualidade de vida do grupo estudado, quando comparado a amostras de pessoas normais em estudos nacionais e internacionais, em particular nos domínios físico, psicológico e de meio ambiente. O domínio relações sociais apresentou a maior média de escores, com 69,7 pontos, enquanto o domínio meio ambiente recebeu a menor pontuação (52,4), ambos na escala percentual. As variáveis associadas a domínio físico foram permanência hospitalar (p=0,02), idade (p<0,01) e sexo (p=0,03). Para os demais domínios, a análise não mostrou associação com as variáveis estudadas. CONCLUSÕES: As vítimas de trauma apresentaram diminuição nos escores de qualidade de vida. Embora o aspecto físico tenha sido o mais atingido, há evidências de que os domínios psicológico e de meio ambiente permaneceram distantes das condições ideais esperadas para a população em geral.

Factors associated to quality of life in active elderly

OBJECTIVE: To analyze whether quality of life in active, healthy elderly individuals is influenced by functional status and sociodemographic characteristics, as well as psychological parameters. METHODS: Study conducted in a sample of 120 active elderly subjects recruited from two open universities of the third age in the cities of São Paulo and São José dos Campos (Southeastern Brazil) between May 2005 and April 2006. Quality of life was measured using the abbreviated Brazilian version of the World Health Organization Quality of Live (WHOQOL-bref) questionnaire. Sociodemographic, clinical and functional variables were measured through crossculturally validated assessments by the Mini Mental State Examination, Geriatric Depression Scale, Functional Reach, One-Leg Balance Test, Timed Up and Go Test, Six-Minute Walk Test, Human Activity Profile and a complementary questionnaire. Simple descriptive analyses, Pearson's correlation coefficient, Student's t-test for non-related samples, analyses of variance, linear regression analyses and variance inflation factor were performed. The significance level for all statistical tests was set at 0.05. RESULTS: Linear regression analysis showed an independent correlation without colinearity between depressive symptoms measured by the Geriatric Depression Scale and four domains of the WHOQOL-bref. Not having a conjugal life implied greater perception in the social domain; developing leisure activities and having an income over five minimum wages implied greater perception in the environment domain. CONCLUSIONS: Functional status had no influence on the Quality of Life variable in the analysis models in active elderly. In contrast, psychological factors, as assessed by the Geriatric Depression Scale, and sociodemographic characteristics, such as marital status, income and leisure activities, had an impact on quality of life.

Trans fatty acid intake among the population of the city of São Paulo, Brazil

OBJECTIVE: To analyze the monounsaturated and polyunsaturated trans fatty acid intake among the general population. METHODS: A cross-sectional study was conducted in São Paulo, Southeastern Brazil, in 2003, on a representative sample of 2,298 male and female subjects, including 803 adolescents (12 to 19 years), 713 adults (20 to 59 years) and 782 elderly people (60 years or over). Food intake was measured using 24-hour recall. Mean trans fatty acid intake was described according to gender and age group. RESULTS: The mean trans fatty acid intake was 5.0 g/day (SE = 0.1), accounting for 2.4% (SE = 0.1) of total energy and 6.8% (SE = 0.1) of total lipids. The adolescents had the highest mean intake levels (7.4 g/day; 2.9% of energy) while the adults and the elderly had similar intake (2.2% of energy for both; 6.4% of lipids and 6.5% of lipids, respectively). The mean trans fatty acid intake among adult and elderly women (approximately 2.5% of energy and 7.0% of lipids) was higher than among men in the same age group. The food item with the highest contribution towards trans fatty acids was margarine, accounting for more than 30% of total intake, followed by filled cookies among adolescents and meat among adults and the elderly. CONCLUSIONS: The trans fatty acid intake is above the level recommended by the World Health Organization. Replacement of the trans fatty acids in manufactured food items may be an effective measure for reducing trans fatty acid intake in Brazil.

Validade do instrumento WHO VAW STUDY para estimar violência de gênero contra a mulher

OBJETIVO: Validar o instrumento do estudo World Health Organization Violence Against Women (WHO VAW) sobre violência psicológica, física e sexual por parceiros íntimos contra mulheres. MÉTODOS: Estudo transversal realizado em vários países entre 2000 e 2003, inclusive Brasil. Selecionaram-se amostras aleatórias e representativas de mulheres de 15-49 anos com parceiros íntimos, residentes na cidade de São Paulo, SP, (n = 940) e na Zona da Mata de Pernambuco (n = 1.188). Realizou-se análise fatorial exploratória das perguntas sobre violências (quatro psicológicas, seis físicas e três sexuais), com rotação varimax e criação de três fatores. Calculou-se alfa de Cronbach para análise da consistência interna. Para a validação por grupos extremos, médias de escores (zero a 13 pontos) de violência foram testadas em relação aos desfechos: auto-avaliação de saúde, atividades diárias, presença de dor ou desconforto, ideação e tentativa de suicídio, grande consumo de álcool e presença de transtorno mental comum. RESULTADOS: Foram definidos três fatores com variância acumulada semelhante (0,6092 em São Paulo e 0,6350 na Zona da Mata). Para São Paulo, o primeiro fator foi determinado pela violência física, o segundo pela sexual e o terceiro pela psicológica. Para a Zona da Mata, o primeiro fator foi composto pela violência psicológica, o segundo pela física e o terceiro pela sexual. Coeficientes de alfa de Cronbach foram 0,88 em São Paulo e 0,89 na Zona da Mata. As médias dos escores de violência foram significativamente maiores para desfechos menos favoráveis, exceto tentativa de suicídio em São Paulo. CONCLUSÕES: O instrumento mostrou-se adequado para estimar a violência de gênero contra a mulher perpetrada por seu parceiro íntimo e pode ser utilizado em estudos sobre o tema. Ele tem alta consistência interna e capacidade de discriminar as formas de violência psicológica, física e sexual, perpetrada em contextos sociais diversos. O instrumento também caracteriza a mulher agredida e sua relação com o agressor, facilitando análises de gênero.

Edentulism and shortened dental arch in Brazilian elderly from the National Survey of Oral Health 2003

OBJECTIVE: To describe the distribution of edentulism and estimate the prevalence of functional dentition and shortened dental arch among elderly population. METHODS: A population-based epidemiological study was carried out with a sample of 5,349 respondents aged 65 to 74 years obtained from the 2002 and 2003 Brazilian Ministry of Health/Division of Oral Health survey database. The following variables were studied: gender; macroregion of residence; missing teeth; percentage that met the World Health Organization goal for oral health in the age group 65 to 74 years (50% having at least 20 natural teeth); presence of shortened dental arch; number of posterior occluding pairs of teeth. The Chi-square test assessed the association between categorical variables. The Kruskal-Wallis and Mann-Whitney tests were used to assess differences of mean between number of posterior occluding pairs teeth, macro-region and gender. RESULTS: The elderly population had an average of 5.49 teeth (SD: 7.93) with a median of 0. The proportion of completely edentulous respondents was 54.7%. Complete edentulism was 18.2% in the upper arch and 1.9% in the lower arch. The World Health Organization goal was achieved in 10% of all respondents studied. However, only 2.7% had acceptable masticatory function and aesthetics (having at least shortened dental arch) and a mean number of posterior occluding pairs of 6.94 (SD=2.97). There were significant differences of the percentage of respondents that met the World Health Organization goal and presence of shortened dental arch between men and women. There were differences in shortened dental arch between macroregions. CONCLUSIONS: The Brazilian epidemiological oral health survey showed high rate of edentulism and low rate of shortened dental arch in the elderly population studied, thus suggesting significant functional and aesthetic impairment in all Brazilian macroregions especially among women.

Associação entre atividade física e qualidade de vida em adultos

OBJETIVO: Sintetizar e analisar as evidências da literatura sobre a associação entre atividade física e qualidade de vida. MÉTODOS: Revisão sistemática nas bases PubMed, Lilacs e SciELO com utilização dos descritores "physical activity", "motor activity", "exercise", "walking", "running", "physical fitness", "sport", "life style", "quality of life", "WHOQOL" e "SF". Foram selecionados 38 estudos publicados entre 1980 e 2010 que utilizaram algum instrumento de medida da atividade física e com alguma versão dos questionários Medical Outcomes Study 36-Item Short-Form Health Survey ou World Health Organization Quality of Life para avaliar a qualidade de vida. RESULTADOS: A maioria dos estudos apresentou delineamento transversal (68%), 18% foram experimentais, 8% de acompanhamento prospectivo (coorte) e 5% com delineamento misto (transversal e longitudinal). O questionário mais utilizado para avaliar a qualidade de vida foi o SF-36 (71%) e a atividade física foi auto-reportada em 82% dos estudos. Maior nível de atividade física associou-se à melhor percepção de qualidade de vida em idosos, adultos aparentemente saudáveis ou em diferentes condições de saúde. CONCLUSÕES: A associação entre atividade física e qualidade de vida é positiva e varia de acordo com o domínio analisado.

Survey of hearing disorders in an urban population in Rondonia, Northern Brazil

OBJECTIVE: To identify the prevalence of hearing loss for the population in the urban area. METHODS: A cross-sectional household survey based on the World Health Organization Ear and Hearing Disorders Survey Protocol was conducted in 298 households in the urban area of Monte Negro, Rondonia, Northern Brazil, from 2005 to 2007. Ear examinations, behavioral audiometry and pure tone audiometry were conducted on 577 individuals. RESULTS: The results showed that 3.8% (95%CI 2.17;5.45) of population were classified in the disabling hearing impairment category. The prevalence of moderate hearing impairment was 3.4%; severe impairment was 0.4%; and profound hearing impairment was not found. CONCLUSIONS: The impairing hearing loss prevalence found in this study is within of the international prevalence for this level of hearing loss and smaller than observed in a previous study in the South region of Brazil.

Adaptacao e validacao do WHODAS 2.0 em utentes com dor musculoesqueletica

OBJETIVO Validar a versão em português do World Health Organization Disability Assessment Schedule (WHODAS 2.0). MÉTODOS A versão original de 36 itens do WHODAS 2.0, administrada por entrevista, foi traduzida para o português de acordo com orientações internacionais e testada em nove participantes da população em geral. A versão em português foi administrada em 204 pacientes com patologia musculoesquelética. Foram coletados os dados sociodemográficos e de saúde dos pacientes, assim como o número de locais onde apresentavam dor e sua intensidade. O WHODAS 2.0 foi novamente administrado por um segundo entrevistador, um a três dias após a primeira entrevista, para avaliar a confiabilidade interavaliadores. A validade de constructo foi avaliada quanto a: capacidade do WHODAS 2.0 para diferenciar participantes com diferentes locais com dor e associação entre o WHODAS 2.0 e a intensidade da dor. A consistência interna também foi avaliada. RESULTADOS A versão portuguesa do WHODAS 2.0 teve fácil compreensão, apresentou boa consistência interna (α = 0,84) e confiabilidade interavaliadores (CCI = 0,95). Mostrou ser capaz de detectar diferenças estatisticamente significativas entre indivíduos com diferente número de locais com dor (p < 0,01) e indicar que maior incapacidade está associada à maior intensidade da dor (r = 0,44, p < 0,01), indicando validade de constructo. CONCLUSÕES A versão portuguesa do WHODAS 2.0 mostrou-se confiável e válida quando utilizada em pacientes com dor associada à patologia musculoesquelética.

Cut-off point for WHOQOL-bref as a measure of quality of life of older adults

OBJECTIVE To propose a cut-off for the World Health Organization Quality of Life-Bref (WHOQOL-bref) as a predictor of quality of life in older adults. METHODS Cross-sectional study with 391 older adults registered in the Northwest Health District in Belo Horizonte, MG, Southeastern Brazil, between October 8, 2010 and May 23, 2011. The older adults’ quality of life was measured using the WHOQOL-bref. The analysis was rationalized by outlining two extreme and simultaneous groups according to perceived quality of life and satisfaction with health (quality of life good/satisfactory – good or very good self-reported quality of life and being satisfied or very satisfied with health – G5; and poor/very poor quality of life – poor or very poor self-reported quality of life and feeling dissatisfied or very dissatisfied with health – G6). A Receiver-Operating Characteristic curve (ROC) was created to assess the diagnostic ability of different cut-off points of the WHOQOL-bref. RESULTS ROC curve analysis indicated a critical value 60 as the optimal cut-off point for assessing perceived quality of life and satisfaction with health. The area under the curve was 0.758, with a sensitivity of 76.8% and specificity of 63.8% for a cut-off of ≥ 60 for overall quality of life (G5) and sensitivity 95.0% and specificity of 54.4% for a cut-off of < 60 for overall quality of life (G6). CONCLUSIONS Diagnostic interpretation of the ROC curve revealed that cut-off < 60 for overall quality of life obtained excellent sensitivity and negative predictive value for tracking older adults with probable worse quality of life and dissatisfied with health.

Women with HIV: gender violence and suicidal ideation

OBJECTIVE To analyze the relationship between gender violence and suicidal ideation in women with HIV. METHODS A cross-sectional study with 161 users of specialized HIV/AIDS care services. The study investigated the presence of gender violence through the Brazilian version of the World Health Organization Violence against Women instrument, and suicidal ideation through the Suicidal Ideation Questionnaire. Statistical analyses were performed with the SPSS software, using the Chi-square test and Poisson multiple regression model. RESULTS Eighty-two women with HIV reported suicidal ideation (50.0%), 78 (95.0%) of who had suffered gender violence. Age at first sexual intercourse < 15 years old, high number of children, poverty, living with HIV for long, and presence of violence were statistically associated with suicidal ideation. Women who suffered gender violence showed 5.7 times more risk of manifesting suicidal ideation. CONCLUSIONS Women with HIV showed a high prevalence to gender violence and suicidal ideation. Understanding the relationship between these two grievances may contribute to the comprehensive care of these women and implementation of actions to prevent violence and suicide.

Prevalence of syphilis in pregnancy and prenatal syphilis testing in Brazil: Birth in Brazil study

OBJECTIVE Determine the coverage rate of syphilis testing during prenatal care and the prevalence of syphilis in pregnant women in Brazil. METHODS This is a national hospital-based cohort study conducted in Brazil with 23,894 postpartum women between 2011 and 2012. Data were obtained using interviews with postpartum women, hospital records, and prenatal care cards. All postpartum women with a reactive serological test result recorded in the prenatal care card or syphilis diagnosis during hospitalization for childbirth were considered cases of syphilis in pregnancy. The Chi-square test was used for determining the disease prevalence and testing coverage rate by region of residence, self-reported skin color, maternal age, and type of prenatal and child delivery care units. RESULTS Prenatal care covered 98.7% postpartum women. Syphilis testing coverage rate was 89.1% (one test) and 41.2% (two tests), and syphilis prevalence in pregnancy was 1.02% (95%CI 0.84;1.25). A lower prenatal coverage rate was observed among women in the North region, indigenous women, those with less education, and those who received prenatal care in public health care units. A lower testing coverage rate was observed among residents in the North, Northeast, and Midwest regions, among younger and non-white skin-color women, among those with lower education, and those who received prenatal care in public health care units. An increased prevalence of syphilis was observed among women with < 8 years of education (1.74%), who self-reported as black (1.8%) or mixed (1.2%), those who did not receive prenatal care (2.5%), and those attending public (1.37%) or mixed (0.93%) health care units. CONCLUSIONS The estimated prevalence of syphilis in pregnancy was similar to that reported in the last sentinel surveillance study conducted in 2006. There was an improvement in prenatal care and testing coverage rate, and the goals suggested by the World Health Organization were achieved in two regions. Regional and social inequalities in access to health care units, coupled with other gaps in health assistance, have led to the persistence of congenital syphilis as a major public health problem in Brazil.

Trends in alcohol and tobacco use among Brazilian students: 1989 to 2010

OBJECTIVE To analyze temporal trends of the prevalence of alcohol and tobacco use among Brazilian students. METHODS We analyzed data published between 1989 and 2010 from five epidemiological surveys on students from the 6th to the 12th grade of public schools from the ten largest state capitals of Brazil. The total sample consisted of 104,104 students and data were collected in classrooms. The same collection tool – a World Health Organization self-reporting questionnaire – and sampling and weighting procedures were used in the five surveys. The Chi-square test for trend was used to compare the prevalence from different years. RESULTS The prevalence of alcohol and tobacco use varied among the years and cities studied. Alcohol consumption decreased in the 10 state capitals (p < 0.001) throughout 21 years. Tobacco use also decreased significantly in eight cities (p < 0.001). The highest prevalence of alcohol use was found in the Southeast region in 1993 (72.8%, in Belo Horizonte) and the lowest one in Belem (30.6%) in 2010. The highest past-year prevalence of tobacco use was found in the South region in 1997 (28.0%, in Curitiba) and the lowest one in the Southeast in 2010 (7.8%, in Sao Paulo). CONCLUSIONS The decreasing trend in the prevalence of tobacco and alcohol use among students detected all over the Country can be related to the successful and comprehensive Brazilian antitobacco and antialcohol policies. Despite these results, the past-year prevalence of alcohol consumption in the past year remained high in all Brazilian regions.

Validation of an instrument to evaluate health promotion at schools

ABSTRACT OBJECTIVE To validate an instrument designed to assess health promotion in the school environment. METHODS A questionnaire, based on guidelines from the World Health Organization and in line with the Brazilian school health context, was developed to validate the research instrument. There were 60 items in the instrument that included 40 questions for the school manager and 20 items with direct observations made by the interviewer. The items’ content validation was performed using the Delphi technique, with the instrument being applied in 53 schools from two medium-sized cities in the South region of Brazil. Reliability (Cronbach’s alpha and split-half) and validity (principal component analysis) analyses were performed. RESULTS The final instrument remained composed of 28 items, distributed into three dimensions: pedagogical, structural and relational. The resulting components showed good factorial loads (> 0.4) and acceptable reliability (> 0.6) for most items. The pedagogical dimension identifies educational activities regarding drugs and sexuality, violence and prejudice, auto care and peace and quality of life. The structural dimension is comprised of access, sanitary structure, and conservation and equipment. The relational dimension includes relationships within the school and with the community. CONCLUSIONS The proposed instrument presents satisfactory validity and reliability values, which include aspects relevant to promote health in schools. Its use allows the description of the health promotion conditions to which students from each educational institution are exposed. Because this instrument includes items directly observed by the investigator, it should only be used during periods when there are full and regular activities at the school in question.
