A cross-sectional approach including dog owner characteristics as predictors of visceral leishmaniasis infection in dogs.

BACKGROUND: Visceral leishmaniasis (VL) is relevant for human and animal public health. Several factors have been associated with the risk of Leishmania infantum infection in dogs. However, dog owner characteristics have been rarely explored. OBJECTIVES: To estimate the prevalence and to identify the associated factors for VL infection including dog owners characteristics. METHODS: A cross-sectional study was conducted including dogs from an endemic canine visceral leishmaniasis (CVL) region in the Federal District, Brazil. The infection was detected using parasitological, serological, and molecular methods. The associated factors were identified through Poisson regression modelling. FINDINGS: The prevalence of infection was 26.25% [95% confidence interval (CI): 20.05 to 33.57]. The associated factors were: short coat prevalence ratio (PR) = 2.33 (95% CI: 1.02 to 5.22); presence of backyard with predominance of soil and/or vegetation PR = 4.15 (95% CI: 1.35 to 12.77); and highest gross family income score PR = 2.03 (95% CI: 1.16 to 3.54). MAIN CONCLUSION: This is the first study that relates higher socioeconomic status of dog owners as an independent factor associated with higher prevalence of VL infection, along with other strongly associated factors related to receptive environment for phlebotomines. Our findings strengthen the need for exploration of the biological and behavioural bases linking dog owner characteristics to the risk of canine infection in prospective cohort studies.

[Corrected estimates of femicides in Brazil, 2009 to 2011]. / Estimativas corrigidas de feminicídios no Brasil, 2009 a 2011.

OBJECTIVE: To estimate the corrected femicide rates and to describe the characteristics of these deaths in Brazil during the 2009-2011 triennium. METHODS: A descriptive study was performed with data from the Brazilian Mortality Information System. Femicides were defined as all female deaths classified in the Assault chapter of ICD-10 (X85-Y09). These data underwent two correction procedures: proportional redistribution of events of undetermined intent (Y10-Y34) and application of correction factors for mortality rates previously described in the literature. RESULTS: During the period analyzed, 13 071 femicides were recorded in the Mortality Information System. After the first correction procedure, 17 167 femicides were estimated, corresponding to a death rate of 5.86 per 100 000 women. Higher femicide rates were recorded in the Northeast, Midwest and North regions of Brazil (6.93, 6.88 and 6.43 deaths per 100 000 women respectively) vs. 5.07 and 5.09 per 100 000 women in the South and Southeast respectively. Of the victims, 29.7% were between 20 and 29 years of age and 60.9% were black. Among women aged 15 years or older, 48% had schooling of not more than 8 years. Fire guns were used in 50.2% of deaths; 27.6% of deaths took place in the household; and 35.1% took place on weekends. CONCLUSIONS: Femicide death rates were high and support the need for correction to reduce underestimation. The victims were women of all age groups, ethnicities, and schooling levels. However, most victims were young, black, with low schooling, living in the Northeast, Midwest, and North of Brazil.

[Spending on private health insurance plans of Brazilian families: a descriptive study with data from the Family Budget Surveys 2002-2003 and 2008-2009]. / Gastos com planos de saúde das famílias brasileiras: estudo descritivo com dados das Pesquisas de Orçamentos Familiares 2002-2003 e 2008-2009.

Spending on health insurance represents an important share of private expenditure on health in Brazil. The study aimed to describe the evolution of spending on private health insurance plans of Brazilian families, according to their income. Data from the Family Budget Surveys (POF) 2002-2003 and 2008-2009 were used. To compare the spending figures among the surveys, the Consumer Price Index (IPCA) was applied. The proportion of families with private health insurance expenses remained stable in both surveys (2002-2003 and 2008-2009), around 24%. However, the household spending on health insurance plans increased. Among those families who spent money oh health insurance plans, the average spending increased from R$154.35 to R$183.97. The average spending on health insurance plans was greater with increasing household income, as well as portions of the family income and total expenditure committed to these expenses. Spending on health insurance is concentrated among higher-income families, for which it was the main component of total health expenditure.

Self-rated health in Brazilian adults and elderly: Data from the National Household Sample Survey 2008 / Percepción de la salud en adultos y ancianos brasileños: datos de la Encuesta Nacional de Hogares 2008

Objective. To investigate prevalence of poor self-rated health and its association with individual and household-level characteristics among adults and elderly in Brazil. Materials and methods. Cross-sectional study with Brazilian National Household Sample Survey 2008 (n=257 816). Crude and multilevel-adjusted Poisson regression models were fitted. Results. After adjusted analysis, poor self-rated health was significantly associated with higher household income, living alone, not having piped water nor garbage collection, lower education, not having health insurance, female sex, higher age, being a current or previous smoker, physical inactivity, having chronic diseases, having physical impairment. Subjects living in rural areas also had higher prevalence of poor self-rated health. The factors most strongly associated with the outcome were physical impairment and reporting three or more chronic diseases. Conclusions. Socioeconomic, health related behaviors, and physical health were associated with poor self-rated health.

Objetivo. Investigar la prevalencia de la percepción negativa de salud y su asociación con características individuales a nivel de los hogares en adultos y adultos mayores de Brasil. Material y métodos. Estudio transversal con datos de la Encuesta Nacional de Hogares de 2008 (n=257 816). Se estimaron modelos de regresión de Poisson multinivel crudos y ajustados. Resultados. Después del análisis ajustado, la autopercepción negativa de salud se asoció significativamente con mayor ingreso, vivir solo, no tener agua corriente ni recolección de basura, baja educación, carecer de seguro de salud, sexo femenino, mayor edad, tabaquismo, inactividad física, enfermedades crónicas y deterioro físico. Los habitantes de zonas rurales también tuvieron mayor prevalencia de percepción negativa. Los factores más fuertemente asociados fueron impedimento físico y presentación de tres o más enfermedades crónicas. Conclusiones. Factores socioeconómicos, comportamientos relacionados con la salud y salud física se asociaron con la percepción negativa.

[Ecological association between characteristics of the municipalities and the risk of homicide in adult males aged 20 to 39 in Brazil: 1999-2010]. / Associação ecológica entre características dos municípios e o risco de homicídios em homens adultos de 20-39 anos de idade no Brasil, 1999-2010.

Homicide mortality remains a major public health problem in Brazil, especially among young adult males. The aim of this study was to assess the homicide mortality risk (HMR) among males aged 20 to 39, and its association with selected socio-demographic characteristics of the Brazilian municipalities. This is an ecologic study in which all the municipalities in Brazil were the unit of analysis. Time trends (from 1999-2002) and adjusted associations between HMR and socio-demographic characteristics of municipalities were estimated in a cross-sectional analysis for 2007-2010 in this study. Between 1999-2002 and 2007-2010, an increasing trend of mean HMR rates from 22.7 to 35.5 per 100,000 inhabitants was observed in Brazil. In 2007-2010, HMR rates were significantly higher (p<0.001) in the largest cities, with higher fertility rates, lower literacy rates, higher social inequality (as estimated by the 20/40 income ratio) and more-urbanized municipalities. Considering the proportion of low income population and the average per capita income, associations with HMR identified greater risks in the intermediary categories of these independent variables. Findings from this study may support the implementation of focal policies directed to more vulnerable municipalities.
