Study summary

The aim of this study is to evaluate if an internet-based CBT (Cognitive Behavioral Therapy) programme for weight stability after LCD (Low Calorie diet) treatment for obesity, can reduce weight gain and improve weight stability, self reported health, pain, eating behavior, fatigue and mood.

Adults with obesity and health problems in primary health care are invited to be part of the study. The geographical area is Orebro county which has in all 29 primary health care centers. Population is 276 000, and according to population studies around 15% of the adult population has a BodyMassIndex (BMI) over 30, which is characterized as obesity according to WHO.

Specific objectives are;

  • To evaluate if internet-based CBT treatment after LCD improves weight stability after 1 and 2 years.
  • To evaluate if weight loss improves metabolic parameters such as HbA1c, blood glucose, Cholesterol, Low density lipoproteins (LDL),High density lipoproteins (HDL) , triglycerides (TG) and Bloodpressure (BP)
  • To evaluate weight loss influence on quality of life, body pain, eating behavior, obesity related problems, fatigue and mood, and to see if CBT program for weight stability also improves these factors
  • To evaluate if LCD treatment is a possible treatment for obesity in ordinary primary health care

Patients taking part in the study, undergo a 12 week period of Low Calorie Diet (LCD) treatment, followed by a 12 week reintroduction to ordinary food. During this period the patient has contact with the primary health care nurse and doctor. After 24 weeks of treatment, the patient who follows the study is supposed to have lost around 10% of initial weight.All patients losing more than 7% weight during the first 24 weeks, are randomized to either ordinary follow up (group 1) or an internet-based CBT programme for weight stability (group 2). All patients in the study are followed at 1 year by doctor, and at 2 year by nurse visit.

Read the detailed description

Patients are recruited in an ordinary primary care setting in Primary care centers in Orebro County. All Primary care centers in the area (26) are invited to take part in the study.

Patients are given brief information at ordinary visits at doctor, nurse or physiotherapists, or by written information announced at the health care center. Before going into the study they need a doctors visit to pass the inclusion and exclusion criteria. The study starts at a nurse visit where the patient gets written information about the LCD treatment and the protocol.

After 24 weeks in the study, all patients with weight loss of 7% or more are randomized into two groups.

Group 1, keep their contact with the nurse at the primary health care centre, and gets a written prescription of physical activity, which is followed by a visit at 36 weeks.

Group 2, gets a code for the internet-based CBT programme. They go into the programme at home, and follow the programme which has the goal of weight stability and contains strategies of meal plans, portion controls, physical activity planning, and cognitive strategies of thinking and goal setting. During this programme there is an opportunity to "chat" with CBT therapists via the internet, concerning the programme and its challenges. No personal meeting with therapist is included.

At 1 year in the study both groups meed with doctor at primary health care center and at 2 year there is a nurse follow up at the same center.

At baseline, 12 weeks, 24 weeks, 1 year and 2 years several validated instruments are used to follow patients wellbeing due to:

  • Quality of life (Short Form -36, SF-36)
  • Obesity related problems (Obesity related Problems Scale version 3 OPv3)
  • Mood (Mood Adjective Chek List MACL)
  • Self reported pain (Brief Pain Inventory Short form BPI-SF)
  • Eating behavior (Three Factor Eating Questionnaire- Revised 21 Items TFEQ-R21)
  • Fatigue (Multidimensional Fatigue Inventory MFI)

We also investigate the patients experiences of the treatment, how they manage to hold on to the diet, and how it effects their motivation for ongoing lifestyle changes. For this we use a study specific instrument.

Inclusion criteria

  • > 30 with health problems and willingness and motivation to make lifestyle changes.
  • Access to the internet and the ability to read and understand written information in swedish.

Exclusion criteria

Exclusion Criteria:

  • \< 30
  • Excessive eating disorder problems (screening forms are used)
  • Severe heart failure ( (NYHA) class III-IV)
  • Moderate or severe (Chronic Obstructive Pulmonary Disease) (FEV% \<50)
  • Uncontrolled asthma (hospitalization or more than twice requiring inhalation treatment on health care site last year)
  • Pregnancy and lactation
  • Type 1 Diabetes
  • Serious liver dysfunction ( value more than doubled, women> 1.5 μkat / L, men> 2.2 μkat / L)
  • Former Gastric bypass surgery or other weight reducing surgery
Terms in these criteria, in plain language(4)

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.

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.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

What researchers measure

Primary outcomes

  1. • Weight reduction in kg and % from baseline to 1 and 2 years

    Patients in the intervention group (Group 2) have an average of 5 kg greater weight loss at 1 year follow-up compared with patients in the control group (Group 1) Out of patients completing 1 year of treatment, 75% reached the weight loss -5%, and 50% have achieved weight loss - 10%

    Time frame: Change from baseline to follow up at 1 and 2 years

Secondary outcomes

  1. • LCD treatment is an effective and suitable treatment for primary health care

    We use a questionnaire that states the patients view about the treatment, and also measurement of how many patients are lost to follow up, or do not go through the full treatment.

    Time frame: Change from baseline to follow up at 1 and 2 years

  2. Improved metabolic control (lower weight and waist circumference, lower TGA) Higher HDL, lower Hba1c

    • Patients , regardless of treatment group, has improved metabolic control (higher HDL, lower TGA, lower weight and waist circumference) compared to baseline measurements at 1 year. Lower fasting plasma glucose (fP-glucose) and HbA1C in subgroup type 2 diabetics at 1 year compared to baseline.

    Time frame: From baseline to 1 year

  3. Quality of life improvements in both groups compared with baseline at one year

    • Quality of life and Obesity problems measured by SF36 and OPv3 improves with weight loss. Self reported pain (BPI-SF), eating behavior (TFEQ-R21), mood (MACL)and fatigue (MFI) also improves with weightloss in both groups. We also want to compare the two groups in order to see if the CBT programme has additional effects on these parameters.

    Time frame: baseline to 1 year

Ran from Mar 2012 to primary completion in Jun 2017, 63 months.

Of 3,683 non-industry interventional studies with no phase under Obesity, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 43. This study's 63 months is above that.

Counting every sponsor, half of 3,846 studies reached it within 22 months; a quarter within 9 and three quarters within 42.

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 Sep 17, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
