Solitary Participation in the "Choking Game" in Oregon.

Objective: The purpose of this study was to compare characteristics of youth who participate in the choking game alone versus those who participate in a group.

Methods: Lifetime prevalence estimates were obtained from the 2011 (n = 5682) and 2013 (n = 15 150) Oregon Healthy Teens survey. The 2011 and 2013 data sets were merged (N = 20 832) to compare youth who participate alone versus those who participate in a group in the choking game.

African-American:White Disparity in Infant Mortality due to Congenital Heart Disease.

Objective: To determine the importance of infant factors, maternal prenatal care use, and demographic characteristics in explaining the racial disparity in infant (age <365 days) mortality due to congenital heart defects (CHD).

Study Design: In this cross-sectional population-based study, stratified and multivariable logistic regression analyses were performed on the 2003-2004 National Center for Health Statistics linked live birth-infant death cohort files of term infants with non-Hispanic white (n = 3 684 569) and African-American (n = 782 452) US-born mothers. Infant mortality rate, including its neonatal (<28 day) and postneonatal (28-364 day) components, due to CHD was the outcome measured.
