“…The results of our study oppose several studies in Brazil, Europe, Asia and North America, which found a higher risk of adverse perinatal outcomes among families of low socioeconomic class, education, and whose parents had manual jobs 13,[15][16][17][18][19]32,34,[40][41][42][43] . The main strength of this study is the use of a random population-based sample (a 1/3 of the births of São Luís' residents), which allows for generalization of the results for the general population of live births.…”

Several studies have identified social inequalities in low birth weight (LBW), preterm birth (PTB), and intrauterine growth restriction (IUGR), which, in recent years, have diminished or disappeared in certain locations. Objectives: Estimate the LBW, PTB, and IUGR rates in São Luís, Maranhão, Brazil, in 2010, and check for associations between socioeconomic factors and these indicators. Methods: This study is based on a birth cohort performed in São Luís. It included 5,051 singleton hospital births in 2010. The chi-square test was used for proportion comparisons, while simple and multiple Poisson regression models with robust error variance were used to estimate relative risks. Results: LBW, PTB and IUGR rates were 7.5, 12.2, and 10.3% respectively. LBW was higher in low-income families, while PTB and IUGR were not associated with socioeconomic factors. Conclusion: The absence or weak association of these indicators with social inequality point to improvements in health care and/or in social conditions in São Luís.

“…Previous research has documented that educated women are less likely to have an LBW baby and maternal education has a 33% protective effect against LBW (14). This has been observed in similar low-resource settings such as Nepal (15) and Bangladesh (16), and in a previous study from Pakistan (17).…”

Facteurs associés à une insuffisance pondérale à la naissance dans les cas de grossesses à terme : étude castémoins appariés au Pakistan rural RÉSUMÉ L'insuffisance pondérale à la naissance demeure un problème de santé publique significatif au Pakistan, et une compréhension approfondie des facteurs associés à ce problème est requise. Nous avons conduit une étude cas-témoins appariés en hôpital afin d'identifier les facteurs de risque associés à l'insuffisance pondérale à la naissance dans un district rural du Pakistan. Il est apparu que l'analphabétisme (OR ajusté : 2,68 ; IC de 95 % : 1,59-4,38), la nulliparité (OR ajusté : 1,82 ; IC de 95 % : 1,26-2,44), les antécédents de fausse couche ou d'avortement (OR ajusté : 1,22; IC de 95 % : 1,06-2,35), le fait d'avoir eu moins de deux visites de soins prénatals au cours de la dernière grossesse, (OR ajusté : 2,43 ; IC de 95 % : 1,34-2,88), de n'avoir recherché des soins prénatals qu'au troisième trimestre (OR ajusté : 3,62

El estudio tuvo como objetivo identificar los factores maternos asociados con el peso al nacer, en Colombia, entre 2002-2011. Fue un estudio descriptivo, basado en información del Registro de Nacido Vivo de Colombia del Departamento Administrativo de Estadísticas Vitales, se clasificó el peso al nacer como: bajo peso al nacer < 2.500g, peso insuficiente 2.500-2.999g, peso adecuado 3.000-3.999g y macrosomía ≥ 4.000g. Para el análisis se utilizó la U Mann-Whitney, Kruskall Wallis y un modelo de regresión logística multinomial. Las mujeres con mayor probabilidad de recién nacidos con bajo peso fueron las de 35 años o más (OR = 1,4; IC95%: 1,39-1,4), con bajo nivel educativo (OR = 1,1; IC95%: 1,1-1,1), solteras (OR = 1,1; IC95%: 1,1-1,2), sin asistencia a controles prenatales (OR = 1,9; IC95%: 1,9-2,0) y de la zona rural (OR = 1,2; IC95%: 1,1-1,2). Las mujeres con mayor prevalencia de recién nacidos macrosómicos fueron de 35 años o más (OR = 1,1; IC95%: 1,1-1,1) y de 4 hijos o más (OR = 2,1; IC95%: 2,0-2,1). El peso insuficiente tuvo un comportamiento similar al bajo peso al nacer. En conclusión, los factores sociodemográficos y maternos influencian el peso al nacer de recién nacidos de mujeres colombianas.

Abstract: The hypothesis of similarity between the extreme degrees of social distribution, translated by maternal education level in relation to the proportion of low birth weight, was not confirmed.
