This paper seeks to quantify the magnitude of caesarean sections in Mexican public health-care institutions in recent years, to characterize the evolution of caesarean section rates (CSR) during the last decade, and to estimate the possible economic cost caused by the excess of caesareans performed in these institutions. The study is based on data obtained from the health sector, both for Mexico in the 5-year period 1993-97 and for the Mexican State of Jalisco between 1983 and 1998. Linear regression analysis was used to evaluate time series, and "excess of caesareans" was considered the number of caesarean deliveries performed above the admissible 15% CSR. The results reflect that on the national level, more than one-quarter of the deliveries handled by public institutions ended in caesarean section for each analyzed year, and if the deliveries performed in private institutions are included, the national rate is around 30%. A marked increase in CSR can be observed in Jalisco between 1983 and 1998 (almost 50%); and the cost for the nation of this CSR excess in financial terms is highly significant: several millions of dollars--obtained from public funds--are spent annually and unnecessarily by health services. The findings suggest that the increase in CSR is a public health problem that has not been satisfactorily faced by the health sector authorities. Many unnecessary caesareans would undoubtedly be avoided if the policies of these public health-care institutions were to consider, as a priority, both the known higher risk implicit in a caesarean for the health of the mother and child, and the economic impact on the country and its health institutions of the excessive number of caesareans performed yearly.
RESUMENObjetivo 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.Palabras Clave: Inequidad en salud, marginación, mortalidad, México (fuente: DeCS, BIREME).

La obesidad eleva el riesgo de morbilidad y mortalidad y se ha relacionado con los hábitos alimentarios y estos con la educación en salud. Esta última tiene como propósito promover la participación de los enfermos en mejorar los comportamientos humanos y estilos de vida saludables y mostrar las ventajas de la educación participativa en la modificación del Índice de Masa Corporal (IMC) en el diabético obeso tipo 2. Se realizó un estudio cuasi experimental con asignación aleatoria de dos grupos de pacientes diabéticos obesos. La intervención educativa-participativa se organizó mediante el proceso de reflexión-acción. Se efectuaron mediciones del IMC basal y mensuales durante los 9 meses de la intervención educativa. Los grupos fueron controlados tomando en cuenta edad y sexo. El análisis estadístico se efectuó con el estadígrafo de t de students con diferencia de media para grupos relacionados. El grupo control logra un valor promedio de IMC basal de 33.89 ± 1.96 y al final de 33.2 ± 2.15 (t: 22.4; p: 0.16), el grupo de experimento con valor inicial de 33.63 ± 2.12 y final de 31.54 ± 1.71 (t: 11.55; p = 0.003). La intervención educativa participativa contribuye a mejorar el nivel de IMC en los diabéticos obesos 2.
The increase in the rate of homicidal violence, especially among young people, is impeding an increase in male life expectancy in Mexico. In several states, such as Chihuahua and Durango, this violence appears to be the main reason for the decline in life expectancy among men aged 15 to 75.
To evaluate impact of working days lost and factors for developing sick leave episodes in Mexicans workers with rheumatoid arthritis (RA). A prospective cohort of 123 patients with RA was followed for 1 year. Factors evaluated for sick leave episodes included: demographics, job characteristics, comorbidity, depressive symptoms, and clinical/therapeutic variables. Rates of sick leave episodes, working days lost, and permanent work disability (PWD) were identified. Statistical analysis included Cox regression models estimating hazard risks (HR) and their 95 % confidence intervals (95% CI). Cumulative time of follow-up for the cohort was 43,380 days, 24 % of workers had at least one episode of sick leave, with a mean of working days lost per patient-year of 18.36; 4.1 % developed PWD. Development of sick leave in the Kaplan-Meier analysis was associated with: age ≥40 years (p = 0.04), having a couple (p = 0.04), performing manual work (p = 0.03), suffering depressive symptoms (p = 0.04), limitations in functioning (p = 0.01), and poor global functional status ≥ III (p = 0.01). Cox regression models identified HAQ-Di ≥ 0.6 as the stronger predictor for sick leave (HR = 4.04, 95 % CI 1.41-11.58, p = 0.009) followed by age (HR = 1.05, 95 % CI 1.01-1.11, p = 0.04), ≥4 risk factors had a HR to 9.4 (95 % CI: 2.1-42.7) for sick leave. In this prospective cohort of Mexican workers with RA, we identified several factors associated with sick leave episodes and working days lost that should be potentially addressed by a multidisciplinary approach, being required to revaluate these strategies with the aim of increasing the work permanence of these patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
