Exploring the association between thyroid- stimulating hormone and metabolic syndrome: A large population-based study

Area of Science:

• Endocrinology
• Cardiology
• Metabolic Health

Background:

• Thyroid-stimulating hormone (TSH) is increasingly recognized for its association with cardiometabolic risk factors.
• Longitudinal data investigating the causal relationship between TSH and metabolic syndrome (MetS) are limited.

Purpose of the Study:

• To explore the causal relationship between TSH levels and the incidence of MetS.
• To analyze the association between TSH and cardiometabolic risk in a large population-based cohort.

Main Methods:

• A longitudinal study involving 25,121 patients from 2010-2016.
• Cox proportional hazard models were used to assess associations between TSH levels and outcomes including MetS, hypertension, prediabetes, and diabetes in 12,463 participants.
• Average follow-up duration was 7.2 years.

Main Results:

• Cross-sectional analysis showed a significant odds ratio (OR) for MetS with higher TSH levels (OR=1.06).
• Longitudinal analysis revealed a significant hazard ratio (HR) for incident MetS associated with the highest TSH quartile compared to the lowest (HR=1.33).
• Elevated TSH levels demonstrated a strong association with the development of MetS.

Conclusions:

• TSH levels are significantly associated with an increased risk of developing metabolic syndrome.
• The findings highlight the importance of monitoring TSH in the context of cardiometabolic health.
• Further research may elucidate the mechanisms underlying the TSH-MetS relationship.
