Health conditions and health-policy innovations in Brazil: the way forward.

Brazil is a large complex country that is undergoing rapid economic, social, and environmental change. In this Series of six articles, we have reported important improvements in health status and life expectancy, which can be ascribed largely to progress in social determinants of health and to implementation of a comprehensive national health system with strong social participation. Many challenges remain, however. Socioeconomic and regional disparities are still unacceptably large, reflecting the fact that much progress is still needed to improve basic living conditions for a large proportion of the population. New health problems arise as a result of urbanisation and social and environmental change, and some old health issues remain unabated. Administration of a complex, decentralised public-health system, in which a large share of services is contracted out to the private sector, together with many private insurance providers, inevitably causes conflict and contradiction. The challenge is ultimately political, and we conclude with a call for action that requires continuous engagement by Brazilian society as a whole in securing the right to health for all Brazilian people.

Violence and injuries in Brazil: the effect, progress made, and challenges ahead

Although there are signs of decline, homicides and traffic-related injuries and deaths in Brazil account for almost two-thirds of all deaths from external causes. In 2007, the homicide rate was 26·8 per 100,000 people and traffic-related mortality was 23·5 per 100,000. Domestic violence might not lead to as many deaths, but its share of violence-related morbidity is large. These are important public health problems that lead to enormous individual and collective costs. Young, black, and poor men are the main victims and perpetrators of community violence, whereas poor black women and children are the main victims of domestic violence. Regional differentials are also substantial. Besides the sociocultural determinants, much of the violence in Brazil has been associated with the misuse of alcohol and illicit drugs, and the wide availability of firearms. The high traffic-related morbidity and mortality in Brazil have been linked to the chosen model for the transport system that has given priority to roads and private-car use without offering adequate infrastructure. The system is often poorly equipped to deal with violations of traffic rules. In response to the major problems of violence and injuries, Brazil has greatly advanced in terms of legislation and action plans. The main challenge is to assess these advances to identify, extend, integrate, and continue the successful ones.

Semantic equivalence of the Portuguese version of the Abuse Assessment Screen tool used for the screening of violence against pregnant women

INTRODUCTION Research programs and actions regarding family violence have been growing steadily. Therefore, theres a need to develop data collection tools. In Brazil, further problems come up since tools that have been developed elsewhere need to be adapted and translated. This study focuses on the Abuse Assessment Screening (AAS) used to detect violence against pregnant women. The objective is to evaluate the semantic equivalence between the original tool in English and two Portuguese versions, and propose a synthetic version to be used in the field. METHODS The evaluation of semantic equivalence was carried out in 4 steps: (1) translation, (2) back translation, (3) formal appreciation of equivalence and (4) a final critical assessment by family violence experts. RESULTS Translation, back translation and the steps 3 and 4 assessment are presented for each item of the tool, along with the original in English. The text covers each discussion that led to the final version. Both versions were quite similar in 14 out of 15 items. Nevertheless, the second version showed to be slightly more adequate although for some items the decision was to combine both versions or, in one case, use an item from version 1. CONCLUSION The procedure undertaken in this study is discussed in the light of Herdman et al.s proposal (1998) regarding transcultural equivalence. The study also stresses the importance of using more than one version in the process and the appropriateness of including an additional step about the assessment of the target populations understanding of the tool.

Portuguese-language cross-cultural adaptation of the Revised Conflict Tactics Scales (CTS2), an instrument used to identify violence in couples

This article concerns the evaluation of cross-cultural equivalence between the Revised Conflict Tactics Scales (CTS2) originally developed in English and used to identify violence in couples and a Portuguese-language version for use in Brazil. Besides a broad literature review, evaluation of conceptual and item equivalences involved expert discussion groups focusing on the existence and pertinence of the underlying theoretical concepts and corresponding component items in the Brazilian context. Semantic equivalence involved the following steps: two translations and respective back-translations; an evaluation regarding referential and general (connotative) equivalence between the original instrument and each version; further discussions with experts in order to define the final version; and pre-testing the latter on 774 women. It was possible to establish high-quality conceptual, item, and semantic equivalence between the Portuguese-language version and the original CTS2. Acceptability of the version was excellent. Although the results were encouraging, they should be reevaluated in the light of forthcoming psychometric analysis (measurement equivalence).

Uma revisão sobre instrumentos de avaliação do estado funcional do idoso

The Comprehensive Geriatric Assessment is characterized as a functional and interdisciplinary evaluation. The first step is the assessment of functional status, which lies at the core of the procedure and can be defined by the level at which an individual performs roles and activities of daily living. Such assessment can be carried out by instruments (questionnaires) whose conceptual framework and psychometric properties must be well-defined. The present study systematically reviewed published data on the properties of the functional status measurement instruments and their adaptation and use in Brazil, through a search of the medical literature in reference textbooks and the LILACS and MEDLINE databases. After selection of the instruments, the next step consisted of a systematic scrutiny of validation, replication, and cultural adaptation studies. Thirty instruments were included according to explicit criteria. Only two, the Medical Outcomes Study SF-36 and the Health Assessment Questionnaire, were found to have equivalence studies in Brazil. However, some of these were apparently used in this country without any formal adaptation. The cultural adaptation of functional status measurement instruments is incomplete and inconsistent in Brazil.

Domestic violence during pregnancy in Rio de Janeiro, Brazil

Objectives: To estimate the prevalence and risk groups of domestic violence during pregnancy among public health care users in Rio de Janeiro, Brazil. The study focuses on violence perpetrated by both women and partners. Method: 526 women giving birth at term in public maternities from March to October 2000 were randomly selected and interviewers used the Revised Conflict Tactics Scales (CTS2). Results: 33.8% [95% confidence interval (CI): 28.8–37.0%] of the respondents reported some form of physical violence and 16.5% (95% CI: 13.3–19.8%) referred to severe forms. A total of 78.3% (95% CI: 74.8–81.8%), 9.9% (95% CI: 7.5–12.7%) and 15.6% (95% CI: 12.6–18.9%) reported psychological aggression, sexual coercion and injuries, respectively. Physical violence mainly occurred among adolescent women with less schooling, who did not work outside the home, with fewer prenatal appointments, and with little social support. Families with more under‐five children, alcohol and drug abuse, and low socio‐economic status were also involved more frequently. Conclusion: High prevalence rates for various forms of domestic violence in Brazil suggest that the issue should be viewed as a major public health problem.

Cross-cultural adaptation of the Portuguese version of the Conflict Tactics Scales Form R (CTS-1) used to assess marital violence: semantic and measurement equivalence

This paper focuses on the cross-cultural adaptation of the Portuguese version of the Conflict Tactics Scales (CTS-1). Semantic equivalence was evaluated with regard to the referential meaning of words and the general connotative meaning of each item. Measurement equivalence between the Portuguese version and the original instrument was assessed by means of the versions psychometric properties, namely, intra-observer reliability, construct validity, internal consistency, and factor structure. For the different relationships, measurement agreement for physical aggression was moderate to substantial. Cronbachs as were high for the physical and verbal aggression scales and low for the negotiation scale. As in the original instrument, factor analysis identified three dimensions, representing the negotiation, verbal aggression, and physical aggression scales, plus a severe physical aggression sub-scale. Although some problems still remain, the overall results suggest an adequate process of cross-cultural adaptation of the CTS-1, thus endorsing its use in the Brazilian setting.

Cross-cultural measurement equivalence of the Revised Conflict Tactics Scales (CTS2) Portuguese version used to identify violence within couples

Following a previous evaluation of concept, item and semantic equivalences, this paper assesses the measurement equivalence between a Portuguese version of Revised Conflict Tactics Scales (CTS2) and the original instrument conceived in English. The CTS2 has been widely used to tap violence between couples. An intra-observer reliability evaluation involved 165 replications carried out within a 24-48 hour period. Kappa point-estimates were above 0.75 for all scales except sexual coercion. The analysis of internal consistency concerned 768 subjects with complete sets of items. Kuder-Richardson-20 estimates ranged from 0.65 to 0.86. Results were similar to those found in the original instrument in English for the negotiation, psychological aggression and physical violence scales, yet not so for the sexual coercion and injury scales. Factor analysis identified factors with a recognizable correspondence to the underlying dimensions, although a few inconsistencies were detected. For the assessment of construct validity (n = 528) associations between the instruments scales were evaluated, as well as the relationships between violence and putative underlying dimensions. Overall, the findings suggest that the version can be used in the Brazilian context, although further investigation should be carried out to unveil some important remaining issues.This study was conducted to establish the frequency of hemoglobinopathies among newborns undergoing screening tests for metabolic diseases at the University Hospital (Hospital de Clínicas) in Porto Alegre, Rio Grande do Sul, Brazil. Testing for abnormal hemoglobins was performed by isoelectric focusing electrophoresis on agarose gel with blood obtained by heel stick and applied to filter paper. For confirmatory testing of abnormal neonatal screening, a venopuncture blood sample was obtained from the infant and parents and then submitted to hemoglobin electrophoresis on cellulose acetate at pH 8.6 and citrate agar at pH 6.2. A total of 1,615 subjects were studied: 20 samples showed the Hb S pattern and six samples showed Hb C. Thus, frequency of the sickle cell gene was 1.2% and that of the Hb C gene was 0.4%, regardless of race or origin. These data suggest that the inclusion of universal neonatal screening for hemoglobinopathies in the ongoing projects for the detection of phenylketonuria and congenital hypothyroidism has many advantages and should be considered in health programs.

Physical activity during pregnancy and maternal-child health outcomes: a systematic literature review

A systematic literature review was conducted to investigate the effects of physical activity during pregnancy on selected maternal-child health outcomes. The search included articles published from 1980 to 2005 in the MEDLINE and LILACS databases using key words such as physical activity, physical exercise, pregnancy, and gestation. The methodological quality of 37 selected articles was evaluated. It appears to be a consensus that some light-to-moderate physical activity is not a risk factor and may even be considered a protective factor for some outcomes. However, some studies found an association between specific activities (e.g., climbing stairs or standing for long periods) and inadequate birth weight, prematurity, and miscarriage. Few studies found an association between physical activity and maternal weight gain, mode of delivery, or fetal development. Further research is needed to fill these gaps and provide guidelines on the intensity, duration, and frequency of physical activity during pregnancy.

Comparison between the abuse assessment screen and the revised conflict tactics scales for measuring physical violence during pregnancy

Study objective: Because of the promise of its ability to quickly identify cases of violence against women during pregnancy, the abuse assessment screen (AAS) should be the focus of numerous psychometric evaluations. This paper assesses its measurement accuracy compared with the revised conflict tactics scales (CTS2) used as standard. Design: Cross sectional study. Besides several ancillary questions, the AAS consists of three anchor questions about violence against pregnant women. These are inclusive, respectively covering lifetime, preceding 12 months, and pregnancy periods. These questions are the main focus of this article. The CTS2 physical aggression scale consists of 12 items divided into minor and severe subscales. A positive event is defined as having at least one positive item in the respective subscale. The 12 item score is also used. Setting and participants: The instruments were applied to 748 women, 24 to 72 hours after delivery in three major public sector maternity wards of Rio de Janeiro from March to September 2000. Main results: According to the CTS2, prevalences of minor and severe physical violence perpetrated against a pregnant woman are 18.4% (95% CI 15.7 to 21.4) and 7.6% (95% CI 5.8 to 9.8), respectively. Taking these subscales as standards, sensitivities are 31.9% (95% CI 24.9 to 40.3) and 61.4% (95% CI 47.6 to 74.0), respectively. Specificities are above 97%. Conclusion: These findings are somewhat worrying because the number of victims who are not identified and offered assistance is considerable. On a practical note, it would be sensible not to use the AAS as a stand alone screening tool until more evidence is gathered.
