Study Details

Study Description

Brief Summary

This study is a single center observational study to investigate the association between biosignals from wearables and thyroid dysfunction.

Condition or Disease Intervention/Treatment Phase
  • Device: Fitbit and Glandy

Detailed Description

An algorithm to predict thyroid dysfunction using heart rate and activity data from wearables was generated based on our previous clinical studies. This study was conducted to collect more data to advance the algorithm.

Patients with thyroid dysfunction including hypothyroidism and thyrotoxicosis were eligible for this study. During the study period, each subject wears a smart band (Fitbit Inspire 2 TM) and gets 3 times of thyroid function tests with 1-month interval. Study participants will use a mobile app (Glandy TM) to collect the symptom scores.

Arms and Interventions

Arm Intervention/Treatment
Thyroid dysfunction group

Subjects with thyroid dysfunction including thyrotoxicosis and hypothyroidism Subjects who were newly diagnosed or undergoing treatment for thyroid dysfunction can be included in the study. Subjects should use a wearable device (Fitbit Inspire 2 TM) and a mobile app (Glandy TM) during the study period.

Device: Fitbit and Glandy
Data collection from wearable devices (Fitbit Inspire 2 TM) and a mobile app (Glandy TM) Fitbit collects user's heart rate, activity, and sleep data. Glandy collects user's subjective symptom scores.

Control group

Subjects without thyroid dysfunction including thyrotoxicosis and hypothyroidism. Subjects should use a wearable device (Fitbit Inspire 2 TM) and a mobile app (Glandy TM) during the study period.

Device: Fitbit and Glandy
Data collection from wearable devices (Fitbit Inspire 2 TM) and a mobile app (Glandy TM) Fitbit collects user's heart rate, activity, and sleep data. Glandy collects user's subjective symptom scores.

Outcome Measures

    serum concentration of free T4

  2. free T4 [visit 3 : 4 weeks after visit 2]

    serum concentration of free T4

  3. free T4 [visit 4 : 4 weeks after visit 3]

    serum concentration of free T4

  4. TSH [visit 2: 1-2 weeks after enrollement (visit 1)]

    serum concentration of TSH

  5. TSH [visit 3 : 4 weeks after visit 2]

    serum concentration of TSH

  6. TSH [visit 4 : 4 weeks after visit 3]

    serum concentration of TSH

  7. heart rate [throughout the study period (average 3 months)]

    continuously monitored heart rate by wearable device

  8. Activity_steps (count/min) [throughout the study period (average 3 months)]

    continuously monitored steps per minute by wearable device

  9. Sleep_sleep start time (yyyy:mm:dd:hh:mm:ss) [throughout the study period (average 3 months)]

    sleep start time extracted from continuously monitored sleep data by wearable device (e.q. 2021:03:15:23:00:00)

  10. Sleep_sleep end time (yyyy:mm:dd:hh:mm:ss) [throughout the study period (average 3 months)]

    sleep end time extracted from continuously monitored sleep data by wearable device (e.q. 2021:03:16:06:00:00)

  11. Hyperthyroid symptom scale [visit 2: 1-2 weeks after enrollement (visit 1)]

    HSS gives scores from 0 to 40, where higher scores indicate more severe disease. It consists of a 10-item scale that rates nervousness, diaphoresis, heat intolerance, motor activity, tremor, weakness, hyperdynamic precordium, diarrhea, weight loss/appetite, and overall function.

  12. Zulewski's clinical score [visit 2: 1-2 weeks after enrollement (visit 1)]

    Clinical scoring system for assessing hypothyroid symptoms and signs (0-12, higher scores indicate more severe)

  13. Hyperthyroid symptom scale [visit 3 : 4 weeks after visit 2]

    HSS gives scores from 0 to 40, where higher scores indicate more severe disease. It consists of a 10-item scale that rates nervousness, diaphoresis, heat intolerance, motor activity, tremor, weakness, hyperdynamic precordium, diarrhea, weight loss/appetite, and overall function.

  14. Zulewski's clinical score [visit 3 : 4 weeks after visit 2]

    Clinical scoring system for assessing hypothyroid symptoms and signs (0-12, higher scores indicate more severe)

  15. Hyperthyroid symptom scale [visit 4 : 4 weeks after visit 3]

    HSS gives scores from 0 to 40, where higher scores indicate more severe disease. It consists of a 10-item scale that rates nervousness, diaphoresis, heat intolerance, motor activity, tremor, weakness, hyperdynamic precordium, diarrhea, weight loss/appetite, and overall function.

  16. Zulewski's clinical score [visit 4 : 4 weeks after visit 3]

    Clinical scoring system for assessing hypothyroid symptoms and signs (0-12, higher scores indicate more severe)
