- A cross-sectional study suggests that patients with metabolic syndrome (MetS) are at increased risk of thyroid nodules and enlarged thyroid volume.
Why this matters
- The relationship between MetS and thyroid nodules/volume is controversial, especially when considering age and sex.
- 26.13% of subjects had thyroid nodules and 29.43% had MetS.
- MetS was associated with increased risk of thyroid nodules in analysis adjusted for age, sex, education, income, smoking status, and salt intake (OR, 1.23; P=.0429).
- Increased thyroid nodule risk was significant in men (OR, 1.38; P=.0228), but not in women (OR, 1.02; P=.8886), although the interaction effect of sex and MetS on thyroid nodules was not statistically significant (P=.94).
- Increased thyroid nodules risk was significant in subjects aged
- MetS and thyroid nodules were both correlated with greater thyroid volume (P=.0037 and P<.0001 respectively>
- 2606 subjects were included and analyzed for associations between MetS, thyroid nodules, and thyroid volume.
