Abstract: objective. to study the association between maternal working conditions and low birth-weight in mexico city. material and methods. interviews of 2 623 workers who gave birth in mexico city hospitals during 1992 were analyzed. information on the main biologic and social factors associated to low birth-weight was registered. occupational stress was determined with the instrument designed by karasek. logistic regression models to evaluate the relationship between working conditions and low birth-weight were used, controlling by confounding variables. results. low birth-weight was more frequent in workers with working periods of more than 50 h/week (or= 1.6; 95% ci= 1.17, 2.28) and with problems at work (or= 1.5; 95% ci= 1.0, 2.25). lack of tangible social support was identified as a risk factor for low birth-weight (or= 1.7; 95% ci= 1.20, 2.33). preventive working measures such as changes in tasks, shortening of working hours and leaves of absence due to illness did not show a beneficial effects on birth-weight, except for the maternity leave of absence. mothers with no right to this had a 2.2 higher probability of giving birth to low weight children (95% ci= 1.66, 2.93). conclusions. these results emphasize the importance of identifying the occupational risk factors during pregnancy.

Abstract: Objetivo. Estudiar la asociación entre condiciones de trabajo materno y bajo peso al nacer en la Ciudad de México. Material y métodos. Se encuestaron 2 623 trabajadoras que atendieron sus partos en tres grandes hospitales de la Ciudad de México en 1992. Se obtuvo información sobre los principales factores biológicos y sociales que se asocian al bajo peso al nacer; asimismo, se determinó el estrés ocupacional utilizando el instrumento desarrollado por Karasek. Se utilizaron modelos de regresión logística para evaluar la relación de las condiciones de trabajo con el bajo peso al nacer, controlando por variables confusoras. Resultados. El bajo peso al nacer fue más alto en trabajadoras con jornadas mayores a 50 horas semanales (RM= 1.6; IC= 1.17, 2.28) y con conflictos laborales (RM= 1.5; IC= 1.0, 2.25). La falta de apoyo social tangible fue identificado como un factor de riesgo de bajo peso al nacer (RM= 1.7; IC= 1.20, 2.33). Las medidas preventivas laborales como el cambio de tareas, disminución de la jornada y las salidas por enfermedad no mostraron un efecto benéfico en el peso al nacer, a excepción de la licencia de maternidad; las madres que no la tuvieron mostraron una probabilidad 2.2 veces mayor para bajo peso al nacer (IC= 1.66, 2.93). Conclusiones. Estos hallazgos resaltan la importancia de identificar los factores de riesgo ocupacional en el embarazo..

Abstract: OBJETIVO: Describir la proporción de embarazo no deseado en adolescentes, su asociación con características sociodemográficas y la utilización de anticonceptivos posparto. MATERIAL Y MéTODOS: Se trata de un estudio transversal con una muestra de 220 mujeres adolescentes entre 13 y 19 a os de edad, de dos municipios semiurbanos del estado de Morelos, México, entrevistadas entre 1992 y 1994. Las mujeres fueron entrevistadas en su casa entre seis y 12 semanas después del parto. Se les preguntó si antes de embarazarse desearon el último embarazo. Además, se indagó sobre conocimientos y uso de métodos anticonceptivos posparto. RESULTADOS: Un 17% de todos los nacimientos registrados en la población total en ese periodo fueron producto de madres adolescentes. De éstas, 22.73% declararon que su embarazo no fue deseado. Se encontró una asociación positiva entre no tener derecho de acceso a los servicios de salud de las instituciones del sistema de seguridad social -Instituto Mexicano del Seguro Social (IMSS), Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado (ISSSTE)- y embarazo no deseado (RM ajustada=3.03, IC 95% 1.31, 7). Asimismo, las adolescentes de comunidades urbanas manifestaron no deseo del embarazo con mayor frecuencia que las mujeres de comunidades rurales (RM ajustada=2.16, IC 95% 1.08, 4.33). Un 91.3% de las madres adolescentes enunció la píldora anticonceptiva entre los métodos que conocía. Un 84.72% conocía el DIU y 63.68% el condón. Sin embargo, sólo 35% estaba utilizando algún método anticonceptivo efectivo después de las seis semanas posparto. No se encontró diferencia en la frecuencia de uso de anticonceptivos según deseo del último embarazo. Entre quienes se atendieron el parto en centros de salud u hospital sólo 43.39% estaba utilizando algún método efectivo de planificación familiar. CONCLUSIONES: Estos hallazgos sugieren que los programas de planificación familiar tienen un potencial de cobertura aún no alcanzado entre el grupo de adolescentes, especialmente entre las que viven en áreas suburbanas y entre las no derechohabientes de la seguridad social. Asimismo, sugiere la necesidad de insistir en la promoción de la utilización de métodos anticonceptivos posparto en este grupo considerado de alto riesgo reproductivo. Además, se evidencia la necesidad de investigar sobre métodos de educación sexual y reproductiva que puedan introducirse en el sistema escolar desde el nivel primario.

Abstract: objective: to identify areas with high risk of infant mortality and any possible correlation with the population’s socioeconomic status through the use of a geographicinformation system and spacial analysis techniques. methods: an exploratory ecologic study was conducted in hermosillo, the capital of sonora, mexico, in 2000-2003. the urban marginalization index (umi) and the infantmortality rate (imr) were determined for each of the city’s basic geostatistical areas(bga). the umi and imr were statistically calculated to identify geographic areas inwhich they were concentrated and to determine the degree of spatial correlation between these indicators. to determine the general spatial autocorrelation and spatialclustering of umis and imrs within the city and the bgas, morans i index, ipop statistics, and besag and newell’s method were employed. results: the mean imr was 14.3 per 1000 live births, higher in the bgas withgreater social marginalization (16.2 per 1000) and lower in those with less (11.7 per 1000). the umi range was -3.1-6.6 (maximum: 4.3; minimum: -2.7). autocorrelation was found among the umi (moran i = 0.62), with significant clustering in the city’s northwest, northeast, and southeast parts. local clustering of high imrs was found in hermosillo’s central and western areas, albeit without autocorrelation (moran i = -0.007). high risk areas (high imr and high umi) were found in the city’s north-western section. conclusions: spatial clusters with high imr were found in socially marginalizedareas in the northwestern part of hermosillo, a city of medium size located in north-western mexico. these results, reached through a combination of spatial analysistechniques and geographic information tools can help guide interventions specifically designed for these high risk residential areas.

Abstract: to explore the association between low caloric intake during pregnancy and intrauterine growth retardation (iugr), a case-control study with 264 cases and 892 controls was conducted in three maternity hospitals in mexico city from january to august 1995. nutritional information on pregnancy was recorded using a previously validated food frequency questionnaire. after adjusting for other known maternal risk factors in the non-conditional logistic regression analysis, for the total sample, caloric intake did not present a direct effect on iugr (or: 0.99; ci 95%: 0.99-1.00). however the odds ratios were as follows for women: with low pre-gestational weight (or: 2.31; ci 95%: 1.59-3.36), in first gestation (or: 1.72; ci 95%: 1.18-2.51), with low birth weight infants (or: 3.54; ci 95%: 1.93-6.46), and presenting hypertension during pregnancy (or: 1.61; ci 95%: 1.00-2.59).

Abstract: Para conocer la asociación entre el consumo de energía en el embarazo y el retraso del crecimiento intrauterino (RCIU), se llevó a cabo un estudio de caso-cohorte en tres hospitales de maternidad de la ciudad de México, entre enero y agosto de 1995. De un total de 4.000 partos que ocurrieron en este período, nos referimos en este estudio a los resultados de un análisis de 264 casos de RCIU y 892 controles. Se procedió a un análisis de regresión logística no condicionada, en el que también se ajustaron los factores maternos potencialmente proclives a la confusión. Para el total de los casos no se observó un efecto directo del consumo de energía en el RCIU (RM: 0,99; IC 95%: 0,99-1,00). Sin embargo, entre las mujeres que comenzaron el embarazo con un peso de 50 kilos o menos, el consumo de energía en relación a RCIU mostró una razón de momios de 2,31 (RM: 2,31; IC 95%: 1,59-3,36); para las mujeres primigestas de 1,72 (RM: 1,72; IC 95%: 1,18-2,51; en aquellas con antecedente de bajo peso al nacer de 3,54 (RM: 3,54; IC 95%: 1,93-6,46) y para aquellas que presentaron tensión arterial alta en el embarazo de 1,61 (RM: 1,61; IC 95%: 1,00-2,59).

Abstract: Objective A growing body of evidence suggests that environmental pollutants, such as heavy metals, persistent organic pollutants and plasticizers play an important role in the development of chronic diseases. Most epidemiologic studies have examined environmental pollutants individually, but in real life, we are exposed to multi-pollutants and pollution mixtures, not single pollutants. Although multi-pollutant approaches have been recognized recently, challenges exist such as how to estimate the risk of adverse health responses from multi-pollutants. We propose an “Environmental Risk Score (ERS)” as a new simple tool to examine the risk of exposure to multi-pollutants in epidemiologic research. Methods and Results We examined 134 environmental pollutants in relation to serum lipids (total cholesterol, high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL) and triglycerides) using data from the National Health and Nutrition Examination Survey between 1999 and 2006. Using a two-stage approach, stage-1 for discovery (n = 10818) and stage-2 for validation (n = 4615), we identified 13 associated pollutants for total cholesterol, 9 for HDL, 5 for LDL and 27 for triglycerides with adjustment for sociodemographic factors, body mass index and serum nutrient levels. Using the regression coefficients (weights) from joint analyses of the combined data and exposure concentrations, ERS were computed as a weighted sum of the pollutant levels. We computed ERS for multiple lipid outcomes examined individually (single-phenotype approach) or together (multi-phenotype approach). Although the contributions of ERS to overall risk predictions for lipid outcomes were modest, we found relatively stronger associations between ERS and lipid outcomes than with individual pollutants. The magnitudes of the observed associations for ERS were comparable to or stronger than those for socio-demographic factors or BMI. Conclusions This study suggests ERS is a promising tool for characterizing disease risk from multi-pollutant exposures. This new approach supports the need for moving from a single-pollutant to a multi-pollutant framework.
