Purpose: The aim of the present study was to evaluate the average sleeping energy expenditure (EE) levels using the SenseWear Armband (SWA) in patients with overt and subclinical hypothyroidism.
Methods: Sixty patients with hypothyroidism and 30 healthy individuals were recruited for the study. Hypothyroid patients were divided into two groups: group 1 (n = 30) consisted of patients with overt hypothyroidism and group 2 (n = 30) consisted of patients with subclinical hypothyroidism. Lastly, group 3 (n = 30) consisted of healthy subjects. The average EE and metabolic equivalent of task (MET) values during sleep of all the hypothyroid participants were analyzed at baseline and at the end of the study. Data were also obtained from the healthy subjects at baseline.
Results: The average sleeping EE and METs values were not significantly different at baseline. Similarly, these values did not change significantly after achieving a euthyroid state via thyroid hormone replacement (both p > 0.05).
Conclusions: Contrary to what has been previously reported , the average sleeping EE and METs values in all hypothyroid patients and healthy individuals were similar at baseline and did not change in the patients with overt and subclinical hypothyroidism after achievement of a euthyroid state.
