To determine trends in mortality from respiratory disease in several areas of Latin America between 1998 and 2009.
The numbers of deaths attributed to respiratory disease between 1998 and 2009 were ...extracted from mortality data from Argentina, southern Brazil, Chile, Costa Rica, Ecuador, Mexico and Paraguay. Robust linear models were then fitted to the rates of mortality from respiratory disease recorded between 2003 and 2009.
Between 1998 and 2008, rates of mortality from respiratory disease gradually decreased in all age groups in most of the study areas. Among children younger than 5 years, for example, the annual rates of such mortality - across all seven study areas - fell from 56.9 deaths per 100,000 in 1998 to 26.6 deaths per 100,000 in 2008. Over this period, rates of mortality from respiratory disease were generally highest among adults older than 65 years and lowest among individuals aged 5 to 49 years. In 2009, mortality from respiratory disease was either similar to that recorded in 2008 or showed an increase - significant increases were seen among children younger than 5 years in Paraguay, among those aged 5 to 49 years in southern Brazil, Mexico and Paraguay and among adults aged 50 to 64 years in Mexico and Paraguay.
In much of Latin America, mortality from respiratory disease gradually fell between 1998 and 2008. However, this downward trend came to a halt in 2009, probably as a result of the (H1N1) 2009 pandemic.
The relation between income and mortality due to violence has been studied in recent years. The Synthesis of Social Indicators of 2002 Sintese de Indicadores Sociais, 2002, published by The Brazilian ...Institute of Geography and Statistics (IBGE), states that one of the most outstanding characteristic of Brazilian society is inequality. The proposal of this ecological study was to test the association between homicide rates, and some health and socioeconomic indicators.
This is an ecological cross-sectional study. Data regarding Sao Paulo City, Brazil in the year 2000 was analyzed. The association between homicide coefficients and the following five indicators were tested: infant mortality rates, monthly average income of household heads, percentage of adolescents aged 15 to 17 years not attending school, proportion of pregnant adolescent women aged 14 to 17 years and demographic density. Pearson's correlation coefficient and a multiple linear regression model were utilized to test these associations.
The municipal homicide rate was 57.3/100,000. The correlation between homicide rates and average monthly income was strong and negative (r=-0.65). Higher homicide rates were found in the districts whose inhabitants had lower incomes and lower rates were found in those districts whose inhabitants had higher incomes. The correlation between homicide rates and proportion of adolescents not attending school was positive and strong (r=0.68). The correlation between homicide rates and the proportion of pregnant adolescent women was positive and strong (r=0.67). The correlation between homicides and the rate of infant mortality was r=0.24 (for all: p<0.05). The correlation between demographic density and homicides was not significant. Although the univariate regression was positive for four indicators, the multivariate regression test was only significant for average monthly income (negative) and proportion of adolescents not attending school (positive) (for both indicators: p<0.01).
The findings highlight the problem of homicides and socioeconomic disparities in S. Paulo City. Economic development and reducing socioeconomic inequality may have an impact on the rates of mortality due to violence.

Metodos El numero de muertes atribuidas a enfermedades respiratorias entre los aros 1998 y 2009 se obtuvo de los datos sobre la mortalidad en Argentina, sur de Brasil, Chile, Costa Rica, Ecuador, ...Mexico y Paraguay y se adaptaron modelos lineales solidos a las tasas de mortalidad por enfermedades respiratorias registradas entre 2003 y 2009.
To analyze the characteristics of visits resulting from land transport injuries.
A total of 5,934 visits in four hospital emergency departments (ED) were analyzed, in the state of São Paulo, in 2005. ...A questionnaire based on the following three models was used to collect data: World Health Organization (WHO), Center for Disease Control and Prevention (CDC), and Pan American Health Organization (PAHO). Variables analyzed were as follows: type of road user (vehicle occupant, pedestrian, motorcyclist, and cyclist), sex, age group, and type of injury suffered. Logistic regression analysis was employed to test associations between variables. Odds ratios with their respective 95% confidence intervals were calculated.
The majority of victims were males (74.2%) in the 20-to-29-year age group (35.0%). Vulnerable road users totaled 72.4% of all cases (29.8% were motorcyclists, 24.1% pedestrians, and 18.5% cyclists). Victims aged between zero and 14 years who had suffered injuries were mostly pedestrians and cyclists; motorcyclists predominated among those aged between 15 and 39 years; and pedestrians among those aged over 50 years. About half of the cases suffered minor injuries (strains, dislocations, contusions and cuts), while the other half was comprised by fractures, traumatic brain injuries and internal injuries. Extremities were the most affected body parts, particularly among motorcyclists. The majority of victims were discharged at triage (87.6%). Compared to women, men were 1.5 times more likely to be admitted or transferred, or to die. Pedestrians, vehicle occupants and motorcyclists were, respectively, 2.7, 2.4 and 1.9 times more likely to be admitted or transferred, or to die than cyclists.
Measures aimed to protect vulnerable road users should be among the priorities to reduce land transport-related injuries.
Increased homicide rates in the city of Sao Paulo, Brazil, in the last two decades points out to the need for better understanding this subject. The purpose of the present study was to link ...information about homicide from different sources of data.
Homicide data from death certificates, medical examiners and police records of residents in the city of Sao Paulo was linked for the second semester of 2001. Variables about victims, risk factors and homicide circumstances were analyzed using absolute numbers, proportions and coefficients. Statistical differences were tested using Pearson's Chi-square test.
Homicide crude rate was 57.2/100,000. Higher rates were observed among men aged 15 to 29 years (56.0% of all cases). The proportion of firearm-related homicides was 88.6%, higher among men than women. Most injuries were to the head (68.9%). Among the victims who underwent to drug screening, 42.5% had high blood alcohol concentrations (44.0% for men and 24.0% for women). Most events occurred at night during weekends and it was found a high correlation (74.6%) between the victim's place of residence and event location.
The study findings highlight that linking information provides better quality of data and allows for better understanding of homicides.
