Authors' conclusion

This epidemiological study in US adults indicates that urinary metal levels are associated with increased CVD risk and mortality.

Study context

Population
Racially diverse US adults from MESA with urinary metals at baseline (2000 to 2001), followed through December 2019
Participants
6,599 adults
Exposure
Highest vs lowest quartile of baseline urinary metals
Outcome
Incident CVD and all-cause mortality
