The Claim

Long-term melatonin prescription use in adults with insomnia is associated with a significantly elevated all-cause mortality rate, with a hazard ratio of 2.09 and a five-year absolute mortality rate of 7.8% compared to 4.3% in non-users.

In plain English

Adults with insomnia who take melatonin long-term appear to have a higher risk of dying from any cause over five years compared to those who don't take it. This suggests that chronic melatonin use might carry hidden health risks for people with sleep problems.

See the scientific wording

All-cause mortality rates are significantly elevated among adults with insomnia who utilize long-term melatonin prescriptions, with a hazard ratio of 2.09 and an absolute mortality rate of 7.8% over five years compared to 4.3% in non-users. This association highlights potential systemic health risks associated with chronic melatonin therapy in individuals with sleep disorders.

    The study analyzed all-cause mortality as a secondary endpoint using stratified Cox regression on a large, matched cohort. The statistically significant hazard ratio of 2.09 and the nearly doubled absolute mortality rates (7.8% vs 4.3%) directly support the claim of an association between chronic melatonin use and increased mortality risk.
