Replication Data for: Making Us Sick? Effects of Partisan Polarization on Health

Partisan polarization is a significant driver of stress and anxiety for the American public, and recent aggregate-level studies suggest polarization may be shaping Americans’ health. This individual-level study uses a new representative dataset of 2752 US residents surveyed between December 2019 and January 2020, testing why some Americans report more days of poor physical and mental health per month than others. Using negative binomial models, zero inflated models, and descriptive visualizations, we find evidence that polarization is detrimental to an individual's physical and mental health; the more distant they feel politically from the average voter in their state, the worse health outcomes they report. By uncovering the individual-level political drivers of health, this study aims to encourage further study and attention to the broader consequences of political polarization on American communities.党派极化（Partisan polarization）是美国民众压力与焦虑的重要诱因，近期的总体层面研究显示，政治极化或正影响着美国人的健康水平。本项个体层面研究采用了2019年12月至2020年1月间调研所得的、涵盖2752名美国居民的全新代表性数据集，旨在探究为何部分美国人每月自述的躯体与心理健康不佳天数多于其他人群。本研究运用负二项模型（negative binomial models）、零膨胀模型（zero inflated models）以及描述性可视化方法，结果证实政治极化对个体的躯体与心理健康均存在损害：个体与所在州平均选民的政治立场差距越大，其自述的健康结局越差。本研究通过揭示健康状况的个体层面政治驱动因素，旨在推动学界进一步关注政治极化对美国社群的广泛影响，并激发相关后续研究。
