Study summary

In this study, investigators measured the number of steps, blood pressure, blood glucose, and weight in daily life through the smartphone personal health record application for patients with type 2 diabetes. The efficacy of text message intervention, which encourages an increase in the number of steps per week for 12 weeks, on an increase in the number of daily steps and changes in glucose levels, weight, and blood pressure will be investigated. Also, the durability of intervention will be checked after 12 weeks of intervention ending.

Read the detailed description

This clinical study is a single institution, randomized, prospective study and monitors the average daily number of steps per week using a smartphone personal health record application developed by Samsung Medical Center for patients with type 2 diabetes. The study subjects were divided into five groups such as 1) basal activity (\<2500 steps/day), 2) limited activity (2500-4999 steps/day), 3) low activity (5000-7499 steps/day), 4) somewhat active (7500-9999 steps/day), 5) active (10000-12499 steps/day), 6) highly active (≥12500 steps/day)according to the average number of steps per day. During the 12-week period, the intervention group receives the text messages that encourage step-by-step increments every week, and the control group does not receive text messages. The effect of 12-week step monitoring and education on the change in daily step count will be analyzed. Also, the effect of change in daily step count on glucose level, body weight, and blood pressure will be studied.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients with Type 2 diabetes aged 20-69 years
  • Patients with a of less than 8.5% measured during screening (may be replaced by a test value within 3 months of screening visit )
  • Patients who have not been prescribed diabetic medication for the past 4 weeks or who have taken more than one oral hypoglycemic agent for more than 12 weeks at a certain dose
  • ≥ 23 kg/m2
  • Available for use Samsung Galaxy S4 or later Android smartphone and wireless internet
  • Patients who voluntarily agreed to participate in this clinical study

Exclusion criteria

Exclusion Criteria:

  • Diabetes other than type 2 diabetes, including type 1 diabetes, gestational diabetes
  • Patients who are taking insulin or GLP-1 agonist other than oral hypoglycemic agent
  • Patients with uncontrolled chronic liver disease
  • Patients with acute kidney injury
  • Patients with psychological disorder

  • Patients with alcohol or drug addiction within the last 3
  • Patients who are taking systemic
  • Patients who are breastfeeding or pregnant
  • Patients who did not voluntarily agree to the study
  • Patients who are unsuitable for participation in clinical research
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Apr 2018 (actual). Primary completion is estimated for Sep 2019, 17 months after the start.

Of 2,066 non-industry interventional studies with no phase under Diabetes Mellitus, Type 2, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 40. This study's planned 17 months is below that.

Counting every sponsor, half of 2,243 studies reached it within 21 months; a quarter within 10 and three quarters within 39.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 25, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
