State-level economic uncertainty and cardiovascular disease deaths: evidence from the United States

This study examines the association between economic uncertainty and mortality from diseases of the circulatory system in the United States. We obtained monthly state-level mortality data from 2008 to 2017 and used indices capturing economic uncertainty from national/international sources and local sources. Panel data modelling was used to account for unobserved time-invariant differences between the states. Our findings suggest that economic uncertainty is independently linked to cardiovascular mortality. Uncertainty arising from national/international sources is associated with cardiovascular deaths, whereas the respective index capturing uncertainty from state/local sources is not. Deaths respond asymmetrically with respect to uncertainty fluctuations – with high levels of uncertainty driving the association. One- and two-month lagged uncertainty levels are also associated with mortality. Several robustness checks further validate the baseline findings. Overall, economic uncertainty is an independent predictor of cardiovascular mortality which appears to act as a psychosocial stressor and a short-term trigger. Public health strategies for cardiovascular disease need to consider factors driving economic uncertainty. Preventive measures and raising awareness can intensify in periods of economic uncertainty.
