Sweden: Study on Tea Intake and Abdominal Aortic Aneurysm

A group of scientists led by Joanna Kaluza conducted a new study in which they showed that tea intake was linked to a lower risk of abdominal aortic aneurysm (AAA). Because of its high antioxidant content, tea has the ability to reduce the incidence of AAA. The risk factors like hypertension, smoking, and hypercholesterolemia may alter this relationship.

The purpose of this study was to investigate the relationship between tea intake and the risk of total, ruptured, and non-ruptured AAA in men and women. This study's findings were reported in the British Journal of Surgery.

Study Details

At the start of the trial, 45,047 men in the Cohort of Swedish Men (COSM) and 36,611 women in the Swedish Mammography Cohort (SMC) were aged 45–83 years. The COSM was founded in 1997 with all males from two central Swedish counties (Västmanland and Örebro), and the SMC was founded in 1987–1990 with women from Västmanland. In 1997 and 2009, food frequency surveys were used to examine tea intake.

Results

• During the 17.5-year follow-up period, 1,781 AAA cases were identified using Swedish registries.
• Tea drinking was shown to be inversely related to total AAA incidence in both men and women.
• Women had a 23% reduced risk of AAA with each cup per day increase, but males had a 9% (0 to 17) lower risk.
• Tea drinking was linked to a decreased incidence of AAA, both non-ruptured and ruptured.
• The connection was moderated by smoking status, with tea drinking linked with a decreased risk of AAA among ex-smokers and never smokers but not in current smokers.
• Tea intake was linked to a decreased risk in both participants with and without hypertension, as well as those with and without hypercholesterolemia.

Conclusion

In conclusion, the points highlighted in this study regarding the consumption of tea open a lot of potential in many cases and their documented beneficial effects.
