Emerging political and demographic divides: State politics, welfare generosity, and adult mortality in U.S. states 1977-2017.

Geographic disparities in adult mortality within the US have grown over the past several decades, but the reasons for these trends remain unclear. In this article, we examine trends in adult mortality (ages 55+) across US states from 1977 to 2017, paying close attention to the shifting geographic pattern of high- and low-mortality states. We find that states in the South tended to fall behind the rest of the country in the 1970s and 1980s, while states in the Great Plains and Mountain West tended to fall behind in the 1990s, 2000s, and 2010s.

Breastfeeding and trajectories of children's cognitive development.

The aim of this study was to examine the association of breastfeeding practices with the growth trajectories of children's cognitive development. We used data from the Child Development Supplement (CDS) of the Panel Study of Income Dynamics (PSID) with variables on presence and duration of breastfeeding and standardized test scores obtained during three different panel waves (N = 2681). After adjusting for covariates we found that breastfed children had higher test scores but that breastfed and non-breastfed children had similar growth trajectories in test scores over time.

Does breastfeeding contribute to the racial gap in reading and math test scores?

Purpose: The aim of this study was to examine the impact of divergent breastfeeding practices between Caucasian and African American mothers on the lingering achievement test gap between Caucasian and African American children.

Methods: The Child Development Supplement of the Panel Study of Income Dynamics, beginning in 1997, followed a cohort of 3563 children aged 0-12 years. Reading and math test scores from 2002 for 1928 children were linked with breastfeeding history.

Does the amount of school choice matter for student engagement?

School choice may increase student engagement by enabling students to attend schools that more closely match their needs and preferences. But this effect on engagement may depend on the characteristics of the choices available. Therefore, we consider how the amount of educational choice of different types in a local educational marketplace affects student engagement using a large, national population of 8th grade students.
