Transição epidemiológica e o estudo de carga de doença no Brasil

No Brasil, a transicao epidemiologica nao tem ocorrido de acordo com o modelo experimentado pela maioria dos paises desenvolvidos. Velhos e novos problemas em saude coexistem, com predominância das doencas cronico-degenerativas, embora as doencas transmissiveis ainda desempenhem um papel importante. Neste estudo, os diferenciais, em relacao ao padrao epidemiologico, sao descritos para o Brasil e grandes regioes, para o indicador de saude dos estudos da carga de doenca, o DALY. Entre os principais resultados encontrados, para o Brasil, destaca-se que o grupo das doencas nao-transmissiveis, infecciosas/parasitarias/maternas/perinatais/nutricionais, e das causas externas representaram, respectivamente, 66,3%, 23,5% e 10,2% da carga total de doenca estimada. A utilizacao do indicador DALY propicia a identificacao de prioridades em funcao do perfil epidemiologico, facilitando a tomada de decisoes e destinacao adequada de recursos por parte dos gestores.

Autoavaliação do estado de saúde e a associação com fatores sociodemográficos, hábitos de vida e morbidade na população: um inquérito nacional

Self-rated health is an important indicator used to measure health perception. This study aimed to investigate the association between self-rated health and social and demographic factors, health behavior, and morbidity. This was a cross-sectional study based on data from a national health survey. The sample consisted of 12,324 individuals from Brazils five major geographic regions. Regression analyses were conducted to verify the association between the outcome and the following independent variables: gender, age, income, education, race, marital status, smoking, alcohol consumption, physical activity, chronic illnesses, and body mass index. Increasing age, low education and income, smoking, sedentary habits, chronic illness, and obesity were the factors most strongly associated with worse self-rated health. The identification of population attributes associated with worse self-rated health can help trace a profile of individuals more prone to seeking health services.Self-rated health is an important indicator used to measure health perception.

Factors associated with malocclusions in children and adolescents with Down syndrome

INTRODUCTION Our aims in this study were to determine the prevalence of malocclusion stemming from vertical or transversal occlusal alterations in subjects with Down syndrome (DS) and the associations with individual, socioeconomic, and behavioral factors. METHODS A cross-sectional study was carried out with 112 pairs of mothers and their children with DS between 3 and 18 years of age attending a genetics clinic at a public hospital in Rio de Janeiro, Brazil. Data were collected with a questionnaire given to the mothers and a clinical examination of the child or adolescent. Univariate, bivariate, and multiple logistic regression (backward stepwise) analyses were conducted. RESULTS The results showed a prevalence of malocclusion in 74% of the sample. After the adjustment of the logistic regression model, these variables--age, nail or finger biting habit, mouth posture, and cold or sore-throat episodes in the previous 6 months--were associated with the prevalence of malocclusions in these subjects. CONCLUSIONS The data demonstrate a high prevalence of malocclusions stemming from vertical or transversal occlusal alterations in children and adolescents with DS. Age, nail or finger biting, mouth posture, and upper airway infections were related to malocclusions in these patients.

Psychometric evaluation of the SF-36 (v.2) questionnaire in a probability sample of Brazilian households: results of the survey Pesquisa Dimensões Sociais das Desigualdades (PDSD), Brazil, 2008.

BackgroundIn Brazil, despite the growing use of SF-36 in different research environments, most of the psychometric evaluation of the translated questionnaire was from studies with samples of patients. The purpose of this paper is to examine if the Brazilian version of SF-36 satisfies scaling assumptions, reliability and validity required for valid interpretation of the SF-36 summated ratings scales in the general population.Methods12,423 individuals and their spouses living in 8,048 households were selected from a stratified sample of all permanent households along the country to be interviewed using the Brazilian SF-36 (version 2). Psychometric tests were performed to evaluate the scaling assumptions based on IQOLA methodology.ResultsData quality was satisfactory with questionnaire completion rate of 100%. The ordering of the item means within scales clustered as hypothesized. All item-scale correlations exceeded the suggested criteria for reliability with success rate of 100% and low floor and ceiling effects. All scales reached the criteria for group comparison and factor analysis identified two principal components that jointly accounted for 67.5% of the total variance. Role emotional and vitality were strongly correlated with physical and mental components, respectively, while social functioning was moderately correlated with both components. Role physical and mental health scales were, respectively, the most valid measures of the physical and mental health component. In the comparisons between groups that differed by the presence or absence of depression, subjects who reported having the disease had lower mean scores in all scales and mental health scale discriminated best between the two groups. Among those healthy and with one, two or three and more chronic illness, the average scores were inverted related to the number of diseases. Body pain, general health and vitality were the most discriminating scales between healthy and diseased groups. Higher scores were associated with individuals of male sex, age below 40 years old and high schooling.ConclusionsThe Brazilian version of SF-36 performed well and the findings suggested that it is a reliable and valid measure of health related quality of life among the general population as well as a promising measure for research on health inequalities in Brazil.

Brazilian multicentre study of common mental disorders in primary care: rates and related social and demographic factors

Problemas de saude mental sao comuns na atencao primaria e sao geralmente relacionados a ansiedade e a depressao. Este estudo tem o objetivo de avaliar a taxa de transtornos mentais comuns e suas associacoes com caracteristicas sociodemograficas em unidades de saude da familia. E um estudo multicentrico, transversal, com os usuarios da atencao primaria do Rio de Janeiro, Sao Paulo, Fortaleza (Ceara) e Porto Alegre (Rio Grande do Sul), Brasil. Utilizou-se o General Health Questionnaire (GHQ-12) e o Hospital Anxiety and Depression Scale (HAD). A taxa de transtornos mentais nos usuarios do Rio de Janeiro, Sao Paulo, Fortaleza e Porto Alegre foram, respectivamente, 51,9%, 53,3%, 64,3% e 57,7%, com diferencas significativas entre Porto Alegre e Fortaleza comparando-se ao Rio de Janeiro. Problemas de saude mental foram especialmente altos em mulheres, desempregados, em pessoas com baixa escolaridade e com baixa renda. Dadas as iniciativas do governo brasileiro para o desenvolvimento os cuidados primarios e para reorganizacao da politica publica de saude mental, e importante considerar os transtornos mentais comuns como uma prioridade tal como outras morbidades cronicas.Mental health problems are common in primary health care, particularly anxiety and depression. This study aims to estimate the prevalence of common mental disorders and their associations with socio-demographic characteristics in primary care in Brazil (Family Health Strategy). It involved a multicenter cross-sectional study with patients from Rio de Janeiro, São Paulo, Fortaleza (Ceará State) and Porto Alegre (Rio Grande do Sul State), assessed using the General Health Questionnaire (GHQ-12) and the Hospital Anxiety and Depression Scale (HAD). The rate of mental disorders in patients from Rio de Janeiro, São Paulo, Fortaleza and Porto Alegre were found to be, respectively, 51.9%, 53.3%, 64.3% and 57.7% with significant differences between Porto Alegre and Fortaleza compared to Rio de Janeiro after adjusting for confounders. Prevalence proportions of mental problems were especially common for females, the unemployed, those with less education and those with lower incomes. In the context of the Brazilian governments moves towards developing primary health care and reorganizing mental health policies it is relevant to consider common mental disorders as a priority alongside other chronic health conditions.

Avaliação da relação entre volume de procedimentos e a qualidade do cuidado: o caso de cirurgia coronariana no Brasil

There is often a negative association between the volume of medical procedures and hospital mortality rates. The objective of this study is to determine whether this association is observed in Brazilian hospitals performing coronary artery bypass grafts (CABG) that were financed by the Ministry of Health. CABG surgeries performed from 1996 to 1998 were analyzed. Data were collected from the Ministry of Health Hospital Information System. The statistical procedure utilized was the Cox survival analysis. Hospitals were grouped in classes of volume of CABG performed. The model was adjusted to the severity of cases (risk of dying). From January 1996 to December 1998 the Ministry of Health reimbursed 41,989 CABG procedures in 131 hospitals. The overall hospital mortality rate was 7.2%. A gradient was observed in the mortality rates. The severity-adjusted risk of dying in the group of hospitals performing more procedures was lower than in the group performing fewer operations. It is recommended that the Ministry of Health strongly consider regionalized concentration of services to perform CABG.

Evaluation of a mental health training intervention for multidisciplinary teams in primary care in Brazil: a pre- and posttest study

OBJECTIVES The aim of this research was to investigate whether a training intervention to enhance collaboration between mental health and primary care professionals improved the detection and management of mental health problems in primary health care in four large cities in Brazil. The training intervention was a multifaceted program over 96 h focused on development of a shared care model. METHOD A quasiexperimental study design was undertaken with assessment of performance by nurse and general practitioners (GPs) pre- and postintervention. Rates of recognition of mental health disorders (compared with the General Health Questionnaire) were the primary outcome, while self-reports of patient-centered care, psychosocial interventions and referral were the secondary outcomes. RESULTS Six to 8 months postintervention, no changes were observed in terms of rate of recognition across the entire sample. Nurses significantly increased their recognition rates (from 23% to 39%, P=.05), while GPs demonstrated a significant decrease (from 42% to 30%, P=.04). There were significant increases in reports of patient-centered care, but no changes in other secondary outcomes. CONCLUSIONS Training professionals in a shared care model was not associated with consistent improvements in the recognition or management of mental health problems. Although instabilities in the local context may have contributed to the lack of effects, wider changes in the system of care may be required to augment training and encourage reliable changes in behavior, and more specific educating models are necessary.

Disponibilidade de medicamentos nas unidades básicas de saúde e fatores relacionados: uma abordagem transversal

RESUMO Este estudo objetivou a caracterizacao da disponibilidade de medicamentos nas unidades basicas de saude (UBS) do Brasil e a identificacao de fatores organizacionais a ela asso ciados, utilizando banco de dados secundarios do Programa Nacional de Melhoria do Acesso e da Qualidade da Atencao Basica. O desfecho relacionado a disponibilidade de medicamentos, expresso de tres diferentes formas, foi explorado em relacao a variaveis explicativas relacionadas a caracteristicas da UBS e a assistencia farmaceutica. Encontrou-se disponibilidade media de 58,5%, que foi tambem baixa em todos os estratos populacionais; houve associacao estatisticamente significativa da variavel desfecho com todas as explicativas. Foi baixa a dis ponibilidade de medicamentos, mostrando-se inversamente associada com a organizacao geral da unidade de saude em geral e da assistencia farmaceutica em particular.

Common mental disorders in Petrópolis-RJ: a challenge to integrate mental health into primary care strategies

OBJECTIVE Common mental disorders are present in more than 50% of patients attending primary care clinics. The main objectives of this study were to detect whether there is any special group of patients within the Family Health Strategy that should be considered to be in greater risk for common mental disorders and to recommend alternative interventions to aid these patients. METHOD In 2002, a cross-sectional study on common mental disorders seen at Family Health Strategy centers was conducted in Petrópolis, State of Rio de Janeiro. RESULTS Common mental disorders were associated with women (OR = 2.90; 95% CI 1.82-4.32), younger than 45 years of age (OR = 1.43; 95% CI 1.02-2.01), with a monthly per capita family income of less than US

Disponibilidade no setor público e preços no setor privado: um perfil de medicamentos genéricos em diferentes regiões do Brasil

40.00 (OR = 1.68; 95% CI 1.20-2.39), and without a partner (OR = 1.71; 95% CI 1.22-2.39). Illiteracy was associated with common mental disorders among patients who were not extremely poor. Social support networks such as going often to church (OR = 0.62; 95% CI 0.43-0.89); participating in artistic and sporting activities (OR = 0.42; 95% CI 0.26-0.70) and having at least four trusted relatives or friends (OR = 0.53; 95% CI 0.31-0.91) was inversely associated with common mental disorders. DISCUSSION Poor women with little social support represent a special group at risk for common mental disorders in the primary care setting. Some countries have developed special interventions to treat patients with common mental disorders in primary care. CONCLUSION Mental health care programs could include evidence-based psychosocial interventions to assist women in overcoming the vicious circle of poverty and dealing with their mental disorders.
