To investigate the causal link between the North American Free Trade Agreement (NAFTA) unrestricted sugar trade agreement signed in 2008 between the USA and Mexico and the diabetes prevalence across all fifty US states.
A quasi-experimental research design to investigate the causal effect of the NAFTA unrestricted sugar trade agreement on diabetes prevalence. Our study utilises a comprehensive panel dataset spanning from 2000 to 2016, comprising 1054 observations. To conduct our analysis, we applied both the difference-in-differences and event-study methodologies.
All the states in the USA.
The fifty states in the USA.
After the enactment of the NAFTA sugar trade agreement between the USA and Mexico in 2008, most states witnessed an increase in diabetes prevalence. The annual impacts displayed significant variation among states, with percentage increases spanning from 0·50 to 2·28 %.
States with a higher percentage of their population living below the poverty line, a larger Black resident population and a lower proportion of high school graduates had more significant increases in diabetes prevalence attributed to the NAFTA sugar trade agreement.
研究 2008 年美国与墨西哥签署的《北美自由贸易协定（NAFTA）》中关于无限制食糖贸易的协议与美国全部 50 个州的糖尿病患病率之间是否存在因果关系。
本研究采用准实验研究设计，旨在调查 NAFTA 无限制食糖贸易协定对糖尿病患病率的因果影响。我们的研究利用了一个涵盖 2000 年至 2016 年的综合面板数据集，包含 1054 个观测值。为进行分析，我们采用了双重差分和事件研究两种方法。
美国所有州。
美国的 50 个州。
2008 年美国与墨西哥之间签署了 NAFTA 食糖贸易协定后，大多数州的糖尿病患病率都有所上升。各州的年影响存在显著差异，百分比增幅在 0.50%至 2.28%之间。
由于 NAFTA 食糖贸易协定，那些贫困人口比例较高、黑人群体较大、高中毕业生比例较低的州，其糖尿病患病率的上升幅度更为显著。
