    ABSTRACT: The Quilombola population is subject to numerous sources of social vulnerability, but few studies investigate their physical or mental health conditions. To investigate the factors associated with depression in men and women, separately. Cross-sectional population-based study with 764 randomly selected participants from five quilombo communities in Vitória da Conquista, Bahia, Brazil. The cutoff point for depression was ≥ 10 points, assessed by the Patient Health Questionnaire score (PHQ-9), and the presence of five or more symptoms. We estimated the prevalence ratio with 95% confidence intervals using Poisson regression models with robust estimators stratified by gender. Among men, factors associated with depression were previous diagnosis of chronic illnesses, poor/very poor health self-assessment, and poor access to health services. Among women, the associated factors were previous diagnosis of psychiatric disorders, poor/very poor health self-perception, history of tobacco smoking, and self-declaration of race as not black. Factors associated with depression differ between men and women and must be considered in interventions to fight depression within this population.

    ABSTRACT: To identify the association between non-adherence to tuberculosis treatment and access to treatment. A cross-sectional study was carried out in the Metropolitan Area of Buenos Aires, Argentina. One hundred twenty three patients notified in 2007 (38 non adherent and 85 adherents) were interviewed regarding the health care process and socio-demographic characteristics. Factors associated to non-adherence were assessed through logistic regression analysis. An increased risk of non-adherence with to treatment was found in male patients (OR = 2.8; 95%CI 1.2 - 6.7), patients who had medical check-ups at hospitals (OR = 3.4; 95%CI 1.1 - 10.0) and those who had difficulties with transportation costs (OR = 2.5; 95%CI 1.1 - 5.9). Risk of non-adherence increases as a result of economic barriers in accessing health care facilities. Decentralization of treatment to primary health care centers and social protection measures for patients should be considered as priorities for disease control strategies in order to lessen the impact of those barriers on adherence to treatment.

    ABSTRACT: To perform a systematic review regarding studies that investigated the association between contextual socioeconomic factors and tooth loss. MEDLINE, Embase, and LILACS databases were searched and no language or date restrictions were applied for this research. The search was also carried out at the Brazilian Library of Theses and Dissertations (BDTD), with the objective of seeking unpublished studies. We evaluated the bibliographical and methodological characteristics of the studies, as well as the findings. We found 348 articles, out of which only 6 were included in this study after revision by 2 independent researchers. We also identified an unpublished thesis. In general, these results show that the socioeconomic context interferes in tooth loss. We found an association between the highest number of missing teeth with less favorable contextual variables, despite the weak evidence, due to the fact that all selected studies had a cross-sectional design. We suggest the standardization of outcome formats and exposures in order to favor the comparison between studies and their quantitative analysis.

    ABSTRACT: This study aimed to assess the nutritional status of vitamin A and associated factors in children assisted in Primary Care Health in Goiânia, Goiás, Brazil. This is a cross-sectional study with a sample of 228 children 12 to 16 months of age. The nutritional status of vitamin A was assessed by serum retinol concentration, determined by high performance liquid chromatography. Multiple linear regression models with hierarchical selection of independent variables were used to evaluate the correlation with serum retinol as the dependent variable. The vitamin A deficiency (retinol < 0,7 μmol/L) was observed in 14,0% of the children. Maternal schooling and hemoglobin concentration were positively correlated with serum retinol concentration, while C-reactive protein showed a negative correlation (R2 = 0,1648). The vitamin A deficiency in one-year-old children attended in Basic Health Units in Goiânia configures itself as a moderate public health problem. Actions to promote maternal education, morbidity control and prevention of other micronutrient deficiencies are important for prevention and control of the vitamin A deficiency in this population.

    ABSTRACT: In epidemiological studies, misclassification error, especially differential misclassification, has serious implications. To illustrate how differential misclassification error (DME) and non-differential misclassification error (NDME) occur in a case-control design and to describe the trends in DME and NDME. Different sensitivity levels, specificity levels, prevalence rates and odds ratios were simulated. Interaction graphics were constructed to study bias in the different settings, and the effect of the different factors on bias was described using linear models. One hundred per cent of the biases caused by NDME were negative. DME biased the association positively more often than it did negatively (70 versus 30%), increasing or decreasing the OR estimate towards the null hypothesis. The effect of the sensitivity and specificity in classifying exposure, the prevalence of exposure in controls and true OR differed between positive and negative biases. The use of valid exposure classification instruments with high sensitivity and high specificity is recommended to mitigate this type of bias.

    ABSTRACT: To estimate the prevalence of underweight, overweight, and obesity among children who were beneficiaries of the Brazil's conditional cash transfer program Bolsa Família during 2010, according to gender and health in the state of Mato Grosso do Sul, Brazil. Descriptive epidemiological study was conducted with a secondary database of Datasus/Sisvan. The data from 19,289 children (9,451 girls and 9,838 boys), aged 5 to 10 years, who benefited from the program Bolsa Família in the state of Mato Grosso do Sul in 2010 were collected. The variables were body weight and height. Body mass index was analyzed with Z-scores of normative tables from the World Health Organization. The prevalence of underweight was 4.8% among female and 5.6% among male participants. The prevalence of overweight and obesity was, respectively, 14.8 and 9.1% for female participants and 16.1 and 11.9% for male participants. The prevalence of underweight and obesity was lower in cities/towns with a lower Human Development Index, for female and male individuals. The prevalence of overweight in cities/towns with a lower Human Development Index was lower among female participants and higher among male participants. The higher prevalence of overweight among individuals of lower socioeconomic status indicates the need for understanding macro-factors that can influence the children's nutritional status.

    ABSTRACT: To estimate the risk of death and readmission of a cohort of elderly patients discharged after hip fracture treatment from hospitals of the public health system; to describe the causes of these events; and to compare the rates of readmission and death observed with those of the elderly population hospitalized in public hospitals of Rio de Janeiro city. Data on deaths and readmissions were obtained through the linkage of these two data sources: the Hospital Information System of the Sistema Único de Saúde and the Mortality Information System from the city of Rio de Janeiro. The time frame for the study was 2008 to 2011. The population consisted of 2,612 individuals aged 60 years or older with nonelective hospitalization for hip fracture who were followed for a year after discharge. The readmission rate in one year, excluding the deaths in this period, was 17.8%, and the death rate was 18.6%. The most common causes of death were circulatory system diseases (29.5%). Approximately 15% of the causes of readmissions were surgical complications. The state hospitals showed lower readmission risks and higher death risks compared with the federal and municipal hospitals. It was observed that there is an excess risk of readmission and hospitalization of the study population compared with the elderly population hospitalized in the public hospitals of the city. Hospitalization of elderly individuals for hip fracture causes adverse outcomes such as readmissions and deaths. Many of these outcomes can be prevented from actions recommended in the National Policy for the Elderly Health.

    ABSTRACT: To investigate the knowledge regarding tuberculosis among relatives of patients with tuberculosis and the possible factors associated with this event and also to conduct comparative analyses between groups of relatives with or with few knowledge regarding tuberculosis, considering their attitudes in both groups. Cross-sectional study in which the sample was obtained through simple and randomized method. The data were collected by trained interviewers and validated tool. Logistic regression analyses were done using statistical software SPSS, version 22.0. Among the 110 subjects recruited for the study, 85 (87.5%) were women, and the mean age was 49 years. Regarding common symptoms of tuberculosis, 102 relatives (90.9%) pointed the chronic cough; regarding the knowledge about tuberculosis transmission modes, 100 (90.9%) of them pointed symptomatic respiratory as the probable infection source. The relatives also reported other tuberculosis transmission models: sharing of clothes (n = 87; 79.1%) and household utensils (n = 66; 60%); sexual relations (n = 50; 50%). Illiterate relatives (adjusted OR = 4.39; 95%CI 1.11 - 17.36), those who do not watch or watch little television (adjusted OR = 3.99; 95%CI 1.2 - 13.26), and also those who do not have the Internet access (adjusted OR = 5.01; 95%CI 1.29 - 19.38) were more likely to have low knowledge regarding tuberculosis. Regardless the group, with or without tuberculosis knowledge, the attitudes of both were satisfactory. There are evidences that social inequity is associated to the tuberculosis knowledge of patient relatives.

    ABSTRACT: To identify factors related to smoking among health workers of the National Health System in Belo Horizonte, Minas Gerais, Brazil. A cross-sectional study based on a survey conducted between September 2008 and January 2009 with a stratified sample. Data on sociodemographic, health, employment, and work characteristics were analyzed. Poisson regression models with robust variance and estimation of unadjusted and adjusted prevalence ratios were used to establish associations at a 5% significance level for inclusion in the final model. In 1,759 questionnaires analyzed, in which the question related to smoking was answered, the overall prevalence of smoking was 15.7%. Reasonable relationship between requirements and available resources remained negatively correlated to smoking in the final model (PR = 0.75; 95%CI 0.58 - 0.96). The variables that remained positively associated with smoking were being male (PR = 1.75; 95%CI 1.36 - 2.25) and the following positions: community health workers (PR = 2.98; 95%CI 1.76 - 5.05), professionals involved in monitoring (PR = 3.86; 95%CI 1.63 - 5.01), administrative and other general services workers (PR = 2.47; 95%CI 1.51 - 4.05); technical mid-level workers (PR = 2.23; 95%CI 1.31 - 3.78), including nurses and practical nurses (PR = 2.07; 95%CI 1.18 - 3.64). Specific occupational subgroups were identified and should be prioritized in smoking cessation and prevention programs.

    ABSTRACT: Cardiovascular diseases are the leading cause of death and hospital expenses in the state of Mato Grosso, Brazil. To describe the temporal variation on risk and protective factors for cardiovascular diseases in adults (≥18 years old). Data were obtained from population-based telephone surveys carried out between 2006 and 2009 in Cuiabá, the capital of Mato Grosso, Brazil. The prevalence of smoking, alcohol abuse, markers of diet quality consumption, physical activities, leisure, domestic work, and commute was estimated. Statistical significance of temporal variations in these estimators was estimated by logistic regression models, whose dependent variables were the analyzed risk factors (absent = 0; present = 1) and independent variable was the year of the survey. There was an increase in the proportion of men who reported to never have smoked (from 53 to 61%, p = 0.04). The frequency of regular soft drink consumption was reduced by 23% (p < 0.01). Overall, the reference to the consumption of fruits and vegetables increased by 19% (p = 0.02), and among men this increase was clearer (49%; p < 0.01). There was a reduction in domestic work (p < 0.01) and in leisure physical activity among women (from 14 to 10%; p = 0.02). Conversely, there was an increase in the proportion of women and individuals older than 40 years of age who make active commuting every day. Favorable changes in cardiovascular risk and protective factors were mostly observed among men, young adults, and those with more than eight schooling years.

    ABSTRACT: Early childhood caries is a persistent worldwide problem. The etiologic contribution of feeding practices has been less frequently investigated in prospective studies of young children. The Porto Alegre Early Life Nutrition and Health Study has followed a birth cohort of 715 mother-child pairs, recruited from municipal health centers, originally involved in a cluster-randomized controlled trial of healthcare worker training. The birth cohort links prospectively collected socio-demographic, infant feeding, and general and oral health information. To date, oral health data, including caries status and oral health-related quality of life, have been collected for 458 children at the age of 2-3 years. Studies are underway to investigate possible determinants and consequences of oral health among these children.

    ABSTRACT: This study aimed to characterize the profile of morbidity among users of family health teams in the northeastern macroregion of Minas Gerais, Brazil. This is a cross-sectional population-based study, developed with the teams of the Family Health Strategy (FHS). It was conducted by data collection, using semi-structured questionnaires with specific instruments adjusted for three categories of professional teams of the FHS: physicians, nurses and community health agents (CHA). We used the International Classification of Primary Care, second edition (ICPC-2) to encode morbidity. Information was collected from 17,988 people, and 10,855 (60.3%) were females; 1,662 (9.2%) questionnaires were related to care by the physician; 2,530 (14.1%) were related to care by nurses and 13,796 (76.7%) corresponded to visits by and meetings with the CHA. The main health problems were: circulatory diseases (especially hypertension), musculoskeletal problems (especially back pain) and diseases of the digestive tract (especially intestinal parasites), which accounted for more than 40% of the medical consultations. Nonspecific complaints and visits related to women's health were the most prevalent in the care by nurses. In meetings with CHA, complaints about respiratory, musculoskeletal and cardiovascular diseases were the most pointed. The morbidity profile observed does not differ substantially from the results of other studies. Small differences can be attributed to regional particularities.
