About this study

Official title: The Impact of Self-quarantining on Glycemic Control, Diabetes Self-management and Distress During the Coronavirus Outbreak

Diabetes mellitus is a chronic disease characterized by the inability of the body to maintain normoglycemia. Treatment of diabetes relies mostly on diabetes self-management, requiring a large investment of time and energy on a daily basis. Psychological wellbeing, behavioral patterns and social context play a major role in diabetes self-management and glycemic control. Social isolation behavior (self-quarantining) may impact glycemic control by influencing daily routines, therapy adherence, physical activity, and self-measurement and eating behaviors. Therefore, a period of nationwide self-quarantine, such as during the lockdown issued during the COVID-19 outbreak in the Netherlands, may have a large effect on glycemic control in patients with diabetes.

In this observational cross sectional study, we aim to assess the impact of long-term self-quarantine on glycemic control, diabetes self-management and distress in patients with type 1 and type 2 diabetes mellitus.

A specific subgroup of patients with T1D are those with complicated diabetes who have received a pancreas or islet transplantation and use immunosuppression, having multiple risk factors for severe COVID-19. The impact of lockdown strategies on mental and physical health is expectedly even greater in patients at even higher risk for severe COVID-19. We therefore additionally investigated differences in behavioral, mental and physical implications of a nationwide lockdown on patients with type 1 diabetes with and without islet or pancreas transplantation.

Measurements will be performed during the lockdown period. Patients will be asked to perform a fingerprick HbA1c measurement once, sent back to the LUMC by mail. Data from continuous or flash glucose monitoring devices will be collected according to standard clinical practice. Furthermore, patients will be asked to fill out an online questionnaire once on diabetes self-management behavior, well-being and distress, along with questions about health status, level of education, medication use, employment, social situation and the impact of self-quarantine on daily routines. In this questionnaire, we ask patients to compare certain aspects of their life (e.g. anxiety, stress, weight, physical activity, glycemic control) at the time of the lockdown to before the lockdown. Data on demographics, type of diabetes, weight, BMI and HbA1c prior to the COVID-19 outbreak will be derived from the patient's electronic health file.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Glycemic control

    HbA1c (mmol/mol Hb)

    Measured: HbA1c measurement during lockdown (8 - 11 weeks after the start of the lockdown (March 15th 2020)) compared to last measurement before lockdown (last known measurement before March 15th 2020)

Secondary outcomes (8)
  1. Glycemic control

    Continuous Glucose Measurement parameters (time in range, time above range, time below range)

    Measured: 2 week period during lockdown compared to 2 week period before lockdown

  2. Stress

    Perceived Stress Scale (PSS) + self-reported change in stress during lockdown compared to before lockdown

    Measured: PSS During lockdown + self-comparison change to before lockdown (questionnaire filled in between 8 - 11 weeks after the start of the lockdown (March 15th 2020))

  3. Anxiety

    Self-reported change in anxiety during lockdown compared to before lockdown

    Measured: Questionnaire filled in between 8 - 11 weeks after the start of the lockdown (March 15th 2020))

  4. Weight

    Self-reported weight change during lockdown compared to before lockdown

    Measured: Questionnaire filled in between 8 - 11 weeks after the start of the lockdown (March 15th 2020))

  5. Physical activity

    Self-reported change in physical activity during lockdown compared to before lockdown

    Measured: Questionnaire filled in between 8 - 11 weeks after the start of the lockdown (March 15th 2020))

  6. Glycemic control and insulin requirements

    Self-reported change in difficulty with glycemic control and insulin requirements during lockdown compared to before lockdown

    Measured: Questionnaire filled in between 8 - 11 weeks after the start of the lockdown (March 15th 2020))

  7. Social isolation behaviour

    Self-reported social isolation behaviour during lockdown

    Measured: Questionnaire filled in between 8 - 11 weeks after the start of the lockdown (March 15th 2020))

  8. Fear of COVID-19 infection

    Fear of contracting COVID-19, scored using a Visual Analogue Scale (1-10), during lockdown

    Measured: Questionnaire filled in between 8 - 11 weeks after the start of the lockdown (March 15th 2020))

Questions about this trial

What is this clinical trial studying?

An observational study of Type 1 Diabetes and Type 2 Diabetes, run by Leiden University Medical Center at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Glycemic control (time frame: HbA1c measurement during lockdown (8 - 11 weeks after the start of the lockdown (March 15th 2020)) compared to last measurement before lockdown (last known measurement before March 15th 2020)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05977205, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Aug 2023.
