Aproximaciones metodológicas al estudio de la mortalidad infantil en Chile

Abstract

Methodological approaches to the study of infant mortality study in ChileIntroduction: Infant Mortality Rate (IMR) is still considered a relevant population health indicator. Knowing related factors and implementation of specifi c policies positively impacts its reduction. Objective: To evaluate the evolution of the studies on infant mortality in Chile in the last three decades. Patients and Methods: A systematic search using Medline, Lilacs and Scielo databases was carried out. Global and component IMR was reviewed. Results: IMR has been reduced considerably since 1980. Sixty-eight papers were found, mostly in national journals and bulletins. Most of them (73.5%) were descriptive studies, although association studies have increased since 2000. The main data source was National Institute of Statistics (47%). The most frequently studied variables were: cause of death (42.6%), maternal age (30.9%) and site (17.6%). Analysis strategies are mostly descriptive, although studies of association most often utilize correlation indices. Conclusion: Infant Mortality continues to be a topic of interest to researchers, who use different strategies. Continued study is encouraged.

Tendencia de la tasa global de fecundidad y el aumento de la fuerza laboral femenina en Chile. 1960-2011

“…Las nuevas políticas deben apuntar a posicionar aun mejor a las mujeres en el mundo laboral y a aspirar que ellas reciban altos niveles de educación; es más, gracias a estos logros se ha impactado favorablemente la reducción de la mortalidad infantil [21][22][23] . Alargar el posnatal, que éste tenga una remuneración adecuada, generación de un incentivo a la maternidad, prolongándolo hasta la incorporación de los hijos a la educación básica, adaptar horarios de trabajo y que existan guarderías que ofrezcan un servicio de calidad, entre varias otras.…”

Evolution of infant mortality in Chile and how it has been reflected in scientific publications between 1980 and 2019

“…The review was conducted by an investigator based on the search and selection developed in advance by researchers that belonged to the same team. 14 The 1980-2016 time series of the IMR was analyzed using the multivariate adaptive regression spline (MARS) method, a technique recommended for this type of data. 15 This is a non-linear regression model based on spline basis function, a generalization of recursive partitioning regression, which divides the space of the predictor variable into different sub-regions and attempts a local approximation in each of them.…”

“…13 Years back, the behavior of the IMR in Chile and the publications related to this indicator were analyzed, and, at that time, the use of time series analysis strategies through non-linear models was discussed. 14 Based on this, the objective of this study was to describe the behavior of the IMR and related published studies in the 1980-2019 period.…”

Evolución de la mortalidad infantil en Chile y su reflejo en las publicaciones científicas entre 1980 y 2019

“…13 Años atrás se estudió el comportamiento d e l a T M I e n C h i l e y l a s p u b l i c a c i o n e s relacionadas con este indicador, y en tal momento se discutió el uso de estrategias de análisis de series de tiempo a través de modelos no lineales. 14 Sobre esa base, el objetivo de este trabajo fue describir el comportamiento de la TMI y los estudios publicados al respecto durante el período 1980-2019.…”
