Violência física entre parceiros íntimos na gestação como fator de risco para a má qualidade do pré-natal

OBJETIVO: Avaliar a violência física entre parceiros íntimos durante a gestação como fator de risco independente para a má qualidade da assistência pré-natal. MÉTODOS: Estudo transversal realizado em três maternidades públicas do município do Rio de Janeiro, RJ. As 528 puérperas incluídas no estudo foram selecionadas em processo de amostragem aleatória simples dentre o conjunto de nascidos vivos a termo em 2000. As informações sobre a assistência pré-natal foram obtidas a partir do cartão da gestante e por meio de entrevistas face a face. Para a avaliação da qualidade da assistência pré-natal utilizou-se o índice de Kotelchuck. Para a identificação das situações de violência, foi utilizada a versão brasileira do instrumento Revised Conflict Tactics Scales. Utilizou-se a regressão logística não condicional para avaliar o efeito da exposição, após controle de variáveis de confusão. RESULTADOS: Mesmo após o ajuste por variáveis socioeconômicas, demográficas, reprodutivas e relativas aos hábitos de vida do casal, a violência física entre parceiros íntimos durante a gestação permaneceu associada à má qualidade da assistência pré-natal. Mulheres que relataram ter sido vítimas de abuso físico durante a gestação possuíam 2,2 vezes mais chance de apresentar uma assistência pré-natal inadequada do que as sem história de violência física. CONCLUSÕES: Os resultados indicam a necessidade do rastreamento de situações de conflito familiar desde o início do pré-natal visando o seu enfrentamento e uma maior adesão das gestantes vitimizadas ao acompanhamento.

Violência contra a mulher ou mulheres em situação de violência? Uma análise sobre a prevalência do fenômeno

Objetivo Refletir sobre as possíveis diferenças entre os termos “violência contra mulher” e “mulheres em situação de violência” com base na análise da ocorrência de violência íntima. Métodos Trata-se de um estudo transversal com uma amostra de 640 mulheres com idade entre 20 e 64 anos, em quatro unidades de Saúde da Família do município de Nova Iguaçu (RJ). Para aferição do evento, foi utilizada a versão em português do instrumento Revised Conflict Tactics Scales, que avaliou as formas – e suas interseções – de violência física, psicológica e sexual sofridas e perpetradas pelas mulheres ao menos uma vez na vida. Resultados Estimou-se a prevalência das três formas de violência íntima praticadas contra a mulher (9,8%; IC95%: 7,5/12,1), pela mulher (4,5%; IC95%: 2,9/6.1) e nos casos que a mulher foi vítima ou perpetradora dos atos (13,1%; IC95%: 10,5/15,7), assumindo-se neste trabalho como violência no casal. Conclusão Na tentativa de melhor entender a dinâmica da violência íntima, seria oportuno considerar a mobilidade de papéis na relação do casal para além da demarcação de gênero – histórica e por vezes imobilizadora – entre vítima e agressor.

Prevalência da violência praticada por parceiro masculino entre mulheres usuárias da rede primária de saúde do Estado de São Paulo

OBJETIVOS: Avaliar a prevalência e fatores associados à violência praticada por parceiro íntimo (VPI), entre mulheres usuárias das Unidades Básicas de Saúde (UBS) do Estado de São Paulo. MÉTODOS: Foi realizado um estudo descritivo de corte transversal, a partir da análise secundária de dados de entrevista a mulheres usuárias de 75 UBS de 15 Departamentos Regionais do Estado de São Paulo, no período de Agosto/2008 a Maio/2009. Foi utilizado questionário baseado no Abuse Assessment Screen e o Conflict Tactics Scales modificado pelo Violence Against Women Study (VAW), estruturado e pré-testado. As variáveis estudadas foram os tipos de VPI (psicológica, física e sexual) e variáveis sociodemográficas (idade, escolaridade, cor da pele, trabalho remunerado, religião, estado marital e classe econômica). Foram entrevistadas 2.379 mulheres de 18 a 60 anos. RESULTADOS: A prevalência de VPI durante a vida foi de 55,7%, sendo a psicológica, física e sexual de 53,8, 32,2 e 12,4%, respectivamente. As mulheres sem companheiro, mas com casamento anterior, com escolaridade <8 anos e da classe econômica mais baixa tiveram maior risco para todos os tipos de VPI, outros fatores ainda foram associados à VIP psicológica e sexual. CONCLUSÕES: A prevalência de VPI nas UBS do Estado de São Paulo é alta. Os profissionais de saúde da atenção primária devem atentar para a detecção da VPI.

Confiabilidade das aferições de estudo sobre violência familiar e desnutrição severa na infância

INTRODUÇÃO: Como parte do programa de investigação sobre violência familiar e desnutrição severa na infância, especificamente um estudo do tipo caso-controle foi avaliada a confiabilidade dos instrumentos utilizados no processo de obtenção de dados. Estudou-se a confiabilidade de quatro componentes do instrumento principal: (a) as Escalas sobre Táticas de Conflitos (Conflicts Tactics Scales - CTS) que medem o grau de conflito/violência familiar; (b) o instrumento CAGE (Cut-down; Annoyed; Guilty & Eye-opener) usado para indicar suspeição de alcoolismo; (c) o NSDUQ (Non-student Drugs Use Questionnaire) que visa aferir o uso de drogas ilícitas; e (d) a medida antropométrica de comprimento. MÉTODO: Para os três primeiros componentes citados foram avaliadas a estabilidade (confiabilidade intra-observador ou teste-reteste) e a equivalência (confiabilidade inter-observador), usando-se os 50 primeiros sujeitos captados no estudo caso-controle de fundo. Para a análise, usou-se o índice Kappa (k) com ajustamento (pseudo-Bayes) para lidar com problemas de estimabilidade. Em relação ao componente "d", foi estudada somente a equivalência (n=73), usando-se o Coeficiente de Correlação Intraclasse (Intra-class Correlation Coefficient - ICC) como estimador. RESULTADOS: Todos os componentes mostraram estabilidade e equivalência aceitáveis. Quanto à estabilidade das CTS, CAGE e NSDUQ, as estimações de k foram em torno de 0,70, 0,78 e 0,85, respectivamente. Em relação à equivalência, encontrou-se os valores de 1,0 para as CTS e NSDUQ e 0,75 para CAGE. A equivalência estimada através do ICC para comprimento foi de 0,99. Algumas situações desviantes foram observadas. Os resultados apontam para uma adequada padronização dos observadores e refletem a boa qualidade do processo de aferição referente ao estudo de fundo, encorajando a equipe de pesquisa a prosseguir com maior segurança.

The coexistence of peace and conflict in South America: toward a new conceptualization of types of peace

South America's predominant democratic regimes and its increasing interdependence on regional trade have not precluded the emergence of militarized crises between Colombia and Venezuela or the revival of boundary claims between Chile and Peru. This way, how can we characterize a zone that, in spite of its flourishing democracy and dense economic ties, remain involved in territorial disputes for whose resolution the use of force has not yet been discarded? This article contends that existing classifications of zones of peace are not adequate to explain this unusual coexistence. Thus, its main purpose is to develop a new analytical category of regional peace for assessing this phenomenon: the hybrid peace. It aims to research the evolution of security systems in South America during the previous century and build a new, threefold classification of peace zones: negative peace zones, hybrid peace zones, and positive peace zones.

ABOUT PSYCHOLOGICAL VARIABLES IN APPLICATION SCORING MODELS

The purpose of this study is to investigate the contribution of psychological variables and scales suggested by Economic Psychology in predicting individuals’ default. Therefore, a sample of 555 individuals completed a self-completion questionnaire, which was composed of psychological variables and scales. By adopting the methodology of the logistic regression, the following psychological and behavioral characteristics were found associated with the group of individuals in default: a) negative dimensions related to money (suffering, inequality and conflict); b) high scores on the self-efficacy scale, probably indicating a greater degree of optimism and over-confidence; c) buyers classified as compulsive; d) individuals who consider it necessary to give gifts to children and friends on special dates, even though many people consider this a luxury; e) problems of self-control identified by individuals who drink an average of more than four glasses of alcoholic beverage a day.

Working hours, work-life conflict and health in precarious and "permanent" employment

OBJECTIVE: The expansion of precarious employment in OECD countries has been widely associated with negative health and safety effects. Although many shiftworkers are precariously employed, shiftwork research has concentrated on full-time workers in continuing employment. This paper examines the impact of precarious employment on working hours, work-life conflict and health by comparing casual employees to full-time, "permanent" employees working in the same occupations and workplaces. METHODS: Thirty-nine convergent interviews were conducted in two five-star hotels. The participants included 26 full-time and 13 casual (temporary) employees. They ranged in age from 19 to 61 years and included 17 females and 22 males. Working hours ranged from zero to 73 hours per week. RESULTS: Marked differences emerged between the reports of casual and full-time employees about working hours, work-life conflict and health. Casuals were more likely to work highly irregular hours over which they had little control. Their daily and weekly working hours ranged from very long to very short according to organisational requirements. Long working hours, combined with low predictability and control, produced greater disruption to family and social lives and poorer work-life balance for casuals. Uncoordinated hours across multiple jobs exacerbated these problems in some cases. Health-related issues reported to arise from work-life conflict included sleep disturbance, fatigue and disrupted exercise and dietary regimes. CONCLUSIONS:This study identified significant disadvantages of casual employment. In the same hotels, and doing largely the same jobs, casual employees had less desirable and predictable work schedules, greater work-life conflict and more associated health complaints than "permanent" workers.

Mid-point for open-ended income category and the effect of equivalence scales on the income-health relationship

To estimate the mid-point of an open-ended income category and to assess the impact of two equivalence scales on income-health associations. Data were obtained from the 2010 Brazilian Oral Health Survey ( Pesquisa Nacional de Saúde Bucal – SBBrasil 2010). Income was converted from categorical to two continuous variables ( per capita and equivalized) for each mid-point. The median mid-point was R$ 14,523.50 and the mean, R$ 24,507.10. When per capita income was applied, 53% of the population were below the poverty line, compared with 15% with equivalized income. The magnitude of income-health associations was similar for continuous income, but categorized equivalized income tended to decrease the strength of association.

Validation of psychosocial scales for physical activity in university students

OBJECTIVE Translate the Patient-centered Assessment and Counseling for Exercise questionnaire, adapt it cross-culturally and identify the psychometric properties of the psychosocial scales for physical activity in young university students.METHODS The Patient-centered Assessment and Counseling for Exercise questionnaire is made up of 39 items divided into constructs based on the social cognitive theory and the transtheoretical model. The analyzed constructs were, as follows: behavior change strategy (15 items), decision-making process (10), self-efficacy (6), support from family (4), and support from friends (4). The validation procedures were conceptual, semantic, operational, and functional equivalences, in addition to the equivalence of the items and of measurements. The conceptual, of items and semantic equivalences were performed by a specialized committee. During measurement equivalence, the instrument was applied to 717 university students. Exploratory factor analysis was used to verify the loading of each item, explained variance and internal consistency of the constructs. Reproducibility was measured by means of intraclass correlation coefficient.RESULTS The two translations were equivalent and back-translation was similar to the original version, with few adaptations. The layout, presentation order of the constructs and items from the original version were kept in the same form as the original instrument. The sample size was adequate and was evaluated by the Kaiser-Meyer-Olkin test, with values between 0.72 and 0.91. The correlation matrix of the items presented r < 0.8 (p < 0.05). The factor loadings of the items from all the constructs were satisfactory (> 0.40), varying between 0.43 and 0.80, which explained between 45.4% and 59.0% of the variance. Internal consistency was satisfactory (α ≥ 0.70), with support from friends being 0.70 and 0.92 for self-efficacy. Most items (74.3%) presented values above 0.70 for the reproducibility test.CONCLUSIONS The validation process steps were considered satisfactory and adequate for applying to the population.

A single method to stain Malassezia furfur and Corynebacterium minutissimum in scales

A single and practical method to slain Malassezia furfur and Corynebacterium minutissimum in lesions' scales is described. The scales are collected by pressing small pieces of scotch tape (about 4 cm lenght and 2 cm width) onto the lesions and following withdrawl the furfuraceous scales will remain on the glue side. These pieces are then immersed for some minutes in lactophenol-cotton blue stain. Following absorption of the stain the scales are washed in current water to remove the excess of blue stain, dried with filter paper, dehydrated via passage in two bottles containing absolute alcohol and then placed in xylene in a centrifugation tube. The xylene dissolves the scotch tape glue and the scales fall free in the tube. After centrifugation and decantation the scales concentrated on the bottom of the tube are collected with a platinum-loop, placed in Canada balsam on a microscopy slide and closed with a cover slip. The preparations are then ready to be submitted to microscopic examination. Other stains may also be used instead of lactophenol-cotton blue. This method is simple, easily performed, and offers good conditions to study these fungi as well as being useful for the diagnosis of the diseases that they cause.

Lutzomyia longipalpis abundance in the city of Posadas, northeastern Argentina: variations at different spatial scales

The distribution of Lutzomyia longipalpis is heterogeneous with a pattern of high abundance areas (HAAs) embedded in a matrix of low abundance areas (LAAs). The objective of this study was to describe the variability in the abundance of Lu. longipalpis at two different spatial levels and to analyse the relationship between the abundance and multiple environmental variables. Of the environmental variables analysed in each household, the condition that best explained the differences in vector abundance between HAA-LAA was the variable "land_grass", with greater average values in the peridomestic environments within the LAA, and the variables "#sp tree", "#pots" and "dist_water" that were higher in the HAA. Of the environmental variables analysed in the patches, the variable "unpaved_streets" was higher in the LAAs and the variable "prop_inf_dogs" was higher in the HAAs. An understanding of the main environmental variables that influence the vector distribution could contribute to the development of strategies for the prevention and control of visceral leishmaniasis (VL). This is the first work in which environmental variables are analysed at the micro-scale in urban areas at the southern edge of the current range of Lu. longipalpis. Our results represent a significant contribution to the understanding of the abundance of the vector in the peridomestic habitats of the region.
