Background: Despite known racial disparities in advance care planning (ACP), little is known about ACP disparities experienced by US immigrants.
Methods: We used data from the 2016 wave of the Health and Retirement Study. We defined ACP engagement as self-reported end-of-life (EOL) discussions, designation of a power of attorney (DPOA), documented living will, or "any" of the three behaviors.
Importance: Because transmission of ocular strains of Chlamydia trachomatis is greatest among preschool-aged children, limiting azithromycin distributions to this age group may conserve resources and result in less antimicrobial resistance, which is a potential advantage in areas with hypoendemic trachoma and limited resources.
Objective: To determine the efficacy of mass azithromycin distributions to preschool-aged children as a strategy for trachoma elimination in areas with hypoendemic disease.
Design, Setting, And Participants: In this cluster randomized clinical trial performed from November 23, 2014, until July 31, 2017, thirty rural communities in Niger were randomized at a 1:1 ratio to biannual mass distributions of either azithromycin or placebo to children aged 1 to 59 months.
