Thyroidstimulating (TSH) higher than controls (3.7±1.8 μIU/mL 2.5±1.7, respectively; p=0.01). prevalence subclinical hypothyroidism (SCH) (p=0.003). There positive TSH (r=0.44, p=0.001). In subgroup analysis, level Group 1 2 (p=0.07). (p=0.03) (p=0.01) group. frequency SCH (p=0.06). (p=0.006) (p=0.002) Conclusion: healthy controls. TSH. We recommend screening
