OBJECTIVES

To estimate associations between gestational age (GA) and teacher-reported academic outcomes at age 9 years among children born at term (37–41 weeks).

METHODS

A secondary data analysis of 1405 children participating in a national US birth cohort study was conducted. At age 9 years, students were evaluated by their teachers in the areas of mathematics, science and social studies, and language and literacy. Unadjusted and adjusted logistic regression models of associations between GA and teacher-reported academic outcomes were estimated and neonatal morbidities were explored as potential pathways.

RESULTS

A continuous measure of GA in weeks was significantly associated with above-average rankings in all areas. The associations were similar across outcomes (eg, mathematics [odds ratio (OR): 1.13; confidence interval (CI): 1.02–1.25], science and social studies [OR: 1.13; CI: 1.01–1.26], and language and literacy [OR: 1.16; CI: 1.05–1.28]) in a model that adjusted for child sex, maternal characteristics, and obstetric risk factors and delivery complications. Other specifications indicate a positive association between late term (41 weeks) and mathematics and a negative association between early term (37–38 weeks) and language and literacy, compared with term (39–40). The associations did not appear to operate through neonatal morbidity.

CONCLUSIONS

The findings highlight the importance of GA, even at term. Whereas current guidelines suggest waiting until at least 39 weeks to deliver when possible, our findings add to a small group of studies suggesting that GA through 41 weeks is associated with improvements in some educational outcomes.
Análisis de gobernabilidad en un sistema socio-ecológico complejo: cuenca del río Caroní, Venezuela
Authors: Sánchez Becker
Published: July 2021

El presente artículo analiza las transformaciones sociopolíticas experimentadas por el Estado venezolano entre 1999 y 2019, las cuales han impactado en la gestión de la cuenca del río Caroní (ubicada al sur del país, de importancia nacional por sus vinculaciones con Colombia y Brasil). El estudio describe los escenarios complejos y los atributos socio-ecológicos que inciden en la gobernabilidad ambiental y que impactan en la gestión de dicha cuenca. Se empleó un enfoque adaptativo de investigación con un protocolo para escalas temporales y espaciales con casos múltiples de estudio. Los resultados muestran relaciones diferenciadas que responden a las culturas socio-institucionales y a los significados de las funcionalidades ecosistémicas construidas por los grupos humanos en medio de acciones colectivas. Se concluye con una definición de gobernabilidad compleja con variables dependientes de límites y vínculos territoriales no específicos, escalas temporales, niveles y/o jurisdicciones administrativas y actores dinámicos que reestructuran y redefinen las prácticas institucionales y comunitarias, ahora con índices incrementados de empoderamiento.
