[Bullying in the metropolitan area of Guadalajara, Mexico: prevalence and associated factors]. / Acoso escolar en la zona metropolitana de Guadalajara, México: prevalencia y factores asociados.

This paper seeks to determine the prevalence of victims of school bullying among youth enrolled in public secondary schools in the metropolitan area of Guadalajara, Mexico and to identify the factors associated with being a victim of bullying in the period 2009-2011. An analytic cross-sectional study was carried out. A multistage probability sampling was designed for the public secondary schools, in which 1,706 students between 11 and 16 years old were studied. A questionnare with four sections was applied in order to identify victims of bullying. A logistic regression model was then used to measure the association between the factors analyzed and being a victim of bullying. The prevalence of school bullying was 17.6% (95% CI 15.8; 19.5). Personal factors, such as the feeling of not being accepted by peers or not spending much time with friends, were the factors with the strongest statistically significant association with being a victim of bullying.

Acoso escolar en la zona metropolitana de Guadalajara, México: prevalencia y factores asociados / Bullying in the metropolitan area of Guadalajara, Mexico: prevalence and associated factors

Este estudio tiene como objetivos determinar la prevalencia de víctimas de acoso escolar en alumnos de escuelas secundarias públicas de la zona metropolitana de Guadalajara, México, e identificar factores asociados al hecho de ser víctima en el período 2009-2011. Se realizó un estudio de tipo transversal analítico. Se diseñó una muestra probabilística polietápica de escuelas secundarias públicas y se estudiaron 1.706 alumnos entre 11 y 16 años. Se aplicó un instrumento con cuatro apartados que permitió identificar a las víctimas de acoso y se utilizó un modelo de regresión logística para medir la asociación entre los factores analizados y el ser víctima de acoso. La prevalencia de acoso escolar fue del 17,6% (IC95% 15,8; 19,5). Factores de carácter personal, como sentir que no es aceptado por el grupo o no pasar mucho tiempo con amigos, fueron los que tuvieron una asociación más fuerte y estadísticamente significativa con el hecho de ser víctima de acoso en la escuela.(AU)

Mortalidad por homicidios en México: tendencias, variaciones socio-geográficas y factores asociados / Deaths by homicide in Mexico: trends, socio-geographical variations and associated factors

Este estudio analiza la tendencia de las tasas de homicidio (total y por arma de fuego) en México entre 1990 y 2009 e identifica las variables que mejor explican las variaciones geográficas de las tasas en el bienio 2008-2009. Se calcularon tasas de homicidios, ajustadas por edad, para ambos sexos entre 1990 y 2009, y para cada estado en 2008-2009. El análisis de regresión lineal múltiple fue usado para identificar factores asociados a las variaciones interestatales de las tasas de homicidio. Los resultados muestran que la tasa de homicidio disminuyó entre 1992 y 2007, pero se ha duplicado en los últimos dos años (de 7.6 a 16.6 por 100,000). En 2009, la tasa de homicidio masculina fue cerca de 9 veces mayor que la tasa femenina y casi dos tercios de los homicidios fueron por arma de fuego. El análisis multivariado revela que la impunidad, el narcotráfico, el consumo de alcohol y drogas y la deserción escolar -por ese orden- son factores claves para entender las variaciones geográficas de las tasas de homicidio en México en 2008-2009. Así, para reducir los homicidios y las variaciones espaciales de la tasa, se necesita no solo combatir a los cárteles de la droga sino sobre todo implementar reformas estructurales en el sistema de procuración de justicia y disminuir las disparidades socioeconómicas entre los estados.

This study seeks to analyze the trend of homicide rates (total and by firearm) in Mexico between 1990 and 2009 and identify the variables that best explain the geographical variations of these rates in the 2008-2009 two-year period. Homicide rates, adjusted for age, were calculated for both sexes between 1990 and 2009 and for each state in 2008-2009. Factors associated with the interstate variations in the homicide rates were identified using multiple linear regression analysis. Results show that the homicide rate in Mexico decreased between 1990 and 2007, but doubled over the last two years (from 7.6 to 16.6 per 100,000). In 2009, the male homicide rate was almost 9 times higher than the female rate and about two-thirds of homicides involved firearms. Multivariate analysis reveals that impunity, drug trafficking, alcohol and drug consumption and school dropout in basic education - in that order - are key factors for understanding the geographical variations in homicide rates in Mexico in 2008-2009. Findings suggest that to reduce the number of homicide victims and spatial variations in the rate, it is necessary not only to fight the drug cartels, but above all to implement structural reforms in the criminal justice system and reduce the socioeconomic disparities among states.

[Demographic characteristics, social inequality and inequity in Mexican childhood health]. / Contexto demográfico, desigualdad social e inequidad en salud de la niñez en México.

OBJECTIVES: Demographically describing the present and future for Mexican children to correlate aspects regarding demographic and social equity during childhood and describing the challenges these variables represent for Mexican children during the next few years. METHODS: The present and future scenario for Mexican childhood was evaluated using existing population projections. Mortality rates were estimated from avoidable causes during childhood per Mexican state, per state grouped by quartile depending on their marginalisation level and by municipality grouped according to their degree of marginalisation. The Gini coefficient was used for measuring inequality. RESULTS: Even though the absolute numbers of children in Mexico will tend to decrease in the future, the number will remain high until 2025. A greatest numbers of children were living in states having the highest degree of social marginalisation. Avoidable mortality was higher in these states compared to states having lower marginalisation. The Gini coefficient was highest concerning mortality rate caused by acute respiratory infection (0.34). Excess of avoidable mortality was evident in municipalities having high and extremely high marginalisation. CONCLUSIONS: Conditions related to demographic ageing and childhood diseases coexist in Mexico. Inequity in children's health is evident; it is related to high levels of social marginalisation. In-depth structural changes are needed to change this situation which will lead to reducing some Mexican populations' unjust social disadvantages.

Contexto demográfico, desigualdad social e inequidad en salud de la niñez en México / Demographic characteristics, social inequality and inequity in Mexican childhood health

Objetivos Caracterizar demográficamente el presente y futuro de la población infantil en México; relacionar condiciones demográficas y equidad social en la niñez y delinear los desafíos que éstas representan para la población infantil mexicana en los próximos años. Métodos A partir de las proyecciones de población existentes se analizó el escenario presente y futuro de la población infantil en México. Se calcularon tasas de mortalidad por causas evitables en la infancia, por estados, por estados agrupados en cuartiles según nivel de marginación y por municipios agrupados según grado de marginación. Para medir la inequidad, se utilizó el coeficiente de Gini Resultados Aunque disminuirá a futuro, el número absoluto de niños en México seguirá siendo elevado hacia 2025; el mayor número de niños reside en los estados con mayor marginación social. Existe un claro exceso de mortalidad evitable en dichos estados en relación con los de menor marginación. El Coeficiente de Gini alcanza su valor más alto en la tasa de mortalidad por infecciones respiratorias agudas (0,34). El exceso de mortalidad evitable es evidente en los municipios de alta y muy alta marginación. Conclusiones Coexisten en México demandas relacionadas con el envejecimiento demográfico, pero también con el notable peso que mantendrá en los próximos años la población infantil; es notoria la inequidad en salud en la niñez, asociada a los altos niveles de marginación social; para modificar esta situación se necesitan profundos cambios estructurales que permitan reducir las desventajas injustas a las que están expuestos importantes núcleos poblacionales del país.

Exclusión social e inequidad en salud en México: un análisis socio-espacial / A socio-spatial analysis of social exclusion and inequity in health in Mexico

Objetivo Determinar la relación existente entre exclusión social e inequidad en salud a nivel estatal y municipal en México en años recientes. Métodos Se calcularon tasas estandarizadas de mortalidad relacionadas con enfermedades trasmisibles en la infancia, el embarazo y el parto así como producto de causas que podrían considerarse potencialmente evitables; estas tasas se calcularon por estados, por estados agrupados en cuartiles según nivel de marginación y por municipios agrupados según grado de marginación. Para medir la inequidad, se utilizaron indicadores como la razón de tasa, el coeficiente de Gini y el índice de inequidades en salud (INIQUIS) Resultados Se observa un claro exceso de mortalidad en los Estados agrupados en el Cuartil IV (mayor marginación) en relación con el Cuartil I (menor marginación) y a la inversa, los recursos y servicios disponibles en el Cuartil I son mayores que los existentes en el Cuartil IV. El Coeficiente de Gini alcanza su valor más alto en la tasa de mortalidad por anemias nutricionales (0,44). El exceso de mortalidad es evidente en los municipios considerados como de muy alta marginación; el INIQUIS más elevado se observa en los Estados ubicados en el Cuartil IV, sobre todo Chiapas, Oaxaca y Guerrero. Conclusiones Existe en México una notoria inequidad en salud, asociada a los altos niveles de exclusión social; para modificar esta situación se necesitan profundos cambios estructurales que impulsen el desarrollo social, y permitan reducir las desventajas injustas a las que están expuestos importantes núcleos poblacionales del país.

Objective Determining the relationship between social exclusion and health inequity at state and municipal level in Mexico during recent years. Methods Adjusted mortality rates were calculated for 2005 (related to transmissible illnesses in childhood, pregnancy, childbirth and being produced by causes considered potentially avoidable); rates were calculated by states, for states grouped in quartiles according to marginalisation level and for municipalities grouped according to degree of marginalisation. Indicators such as rate ratio, Gini coefficient and the inequities in health index (IHI) were used for measuring such inequity, Results A clear excess of mortality was observed in the states grouped in the 4th quartile (highest marginalisation) in relationship to the 1st quartile (lowest marginalisation); conversely, resources and health services in the 1st quartile were evidently higher than those in the 4th quartile. The Gini coefficient reached its highest value in the mortality rate for nutritional anaemia (0.44). Excess mortality was evident in those municipalities considered as having very high marginalisation; the highest IHI was observed in the states located in the 4th quartile (Chiapas, Oaxaca and Guerrero) when analysing mortality related to childhood, pregnancy, childbirth and potentially avoidable mortality. Conclusions Notorious health inequality exists in Mexico, associated with high prevalent levels of social exclusion in different areas of the country. Deep structural changes are needed to modify this situation, promote social development and lead to reducing the unfair disadvantages to which important population groups are exposed.
