Executive Summary
This study is the first to investigate the relationship between coffee consumption and telomere length in individuals with severe mental disorders such as schizophrenia and affective disorders. Previous research suggests accelerated telomere shortening and increased coffee consumption in this patient group. The authors expect that moderate coffee consumption is associated with longer telomeres.
Core Topic & Context
- Severe mental disorders are associated with a 15-year reduction in life expectancy, possibly due to accelerated cellular aging (telomere shortening).
- Coffee is one of the most widely consumed beverages worldwide and can have both positive and negative effects on health.
Key Facts & Figures
- An estimated 10.56 billion kilograms of coffee were consumed worldwide in 2021/22.
- In a sample of 468,629 participants from the UK Biobank, 77.9% drank coffee, with 19.5% consuming more than 3 cups per day.
- Health authorities recommend a maximum of 400 mg of caffeine per day, which is equivalent to about 4 cups of coffee.
- Studies show that people with mental disorders consume significantly more caffeine than healthy control subjects.
Stakeholders & Affected Parties
- Affected individuals are people with severe mental disorders such as schizophrenia and affective disorders.
- The coffee and tobacco industries as well as the healthcare sector are involved.
Opportunities & Risks
- Excessive coffee consumption can lead to sleep disorders, irritability, cardiovascular problems, and other side effects.
- Moderate coffee consumption may potentially protect against telomere shortening due to its antioxidant properties.
Current State of Research
- There are conflicting results regarding the relationship between coffee consumption and telomere length in the general population.
- This is the first study to investigate this relationship in individuals with severe mental disorders.
