The effect of lifestyle treatment on physical capacity, maximal strength, eating behavior and quality of life in patients with morbid obesity (LIFETIME)
In this study, the investigators will investigate whether more intensive day-based lifestyle treatment process have a better effect on weight loss and health-related quality of life than a previous treatment. Investigators also want to investigate whether patients with good physical capacity (maximal oxygen uptake) and bone strength (maximum bone strength) before initiating treatment and / or after 3 and 6 months intensive training may have greater weight loss 1 and 2 years after treatment than patients with lower physical capacity and bone strength.
985 studies on the registry are indexed under Feeding Behavior; 178 are open to participants now.
This study's planned enrollment of 600 is above the median of 77 across 700 interventional studies indexed under Feeding Behavior.

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.

Lifestyle treatment
Weight change at 2-year follow up
Effect of intensive treatment on weight loss changes at 2- year follow up. Body weight was measured with patients wearing light clothing and no shoes on Scanvaegt DS-530 (Århus, Denmark) at baseline and at 2-year follow up.
Time frame: Changes from baseline body weight at 2-year follow up.
Maximal leg strength change at 2-year follow up
Maximum leg strength will be measure with a bone press device (OPS161 Interchangeable Leg Press) at baseline, after 3-6 month and 1-2 years. The test will be conduct as an individual adapted protocol with gradual loading until voluntary maximum bone strength is achieve.
Time frame: Changes from baseline maximal leg strenght at 2-year follow up.
Physical capacity change at 2-year follow up
Physical capacity will be measure as maximum oxygen uptake (VO2max) by indirect calorimetry (Jaeger Oxycone Pro) at baseline, after 3-6 month and 1-2 years. Indirect calorimetry is to be regard as a gold standard for measurement of maximum oxygen uptake.
Time frame: Changes from baseline physical capacity at 2-year follow up.
Health-related quality of life (HRQoL) - Short Form Health Survey (RAND-36), change at 2-year follow up
The patient reported outcome measurements (PROMS) comprise three elements; generic and obesity specific health related quality of life (HRQoL) and obesity specific symptoms measured at baseline, 3 months, 6 months, 1 year and 2 years. The RAND-36 is a 36-item measure of generic HRQOL consisting of eight additive subscales (Physical Functioning, Role Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role Emotional, and Mental Health) and two summary scores each based on four subscales (Physical Component Summary and Mental Component Summary). Scores on all subscales range from 0 to 100. Summary-scores will be norm-based, with mean (SD) 50 (10). Higher scores on all scales represent better HRQOL.
Time frame: Changes from baseline RAND-36 at 2-year follow up.
Health-related quality of life (HRQoL) - Impact on Weight Questionnaire (IWQOL-Lite), change at 2-year follow up
The patient reported outcome measurements (PROMS) comprise three elements; generic and obesity specific health related quality of life (HRQoL) and obesity specific symptoms measured at baseline, 3 months, 6 months, 1 year and 2 years. The IWQOL-Lite is a 31-item measure of weight-related quality of life. There are five domain scores (Physical Function, Self-Esteem, Sexual Life, Public Distress and Work) and a total score. Scores for all domains and total score range from 0-100, with lower scores indicating greater impairment.
Time frame: Changes from baseline IWQOL-Lite at 2-year follow up.
Health-related quality of life (HRQoL) - Weight-Related Symptom Measure (WRSM), change at 2-year follow up
The patient reported outcome measurements (PROMS) comprise three elements; generic and obesity specific health related quality of life (HRQoL) and obesity specific symptoms measured at baseline, 3 months, 6 months, 1 year and 2 years. The WRSM is a 20-item measure for the presence and distress of 20 weight-related symptoms. The distress scores of the symptoms are reported on a six-point likert scale. Two summary scores are calculated; an additive score of presence of symptoms ranging from 1 to 20 and a symptom distress score for all symptoms. Symptom distress scores range from 0 to 100, with higher scores indicating a higher or worse total symptom distress.
Time frame: Changes from baseline WRSM at 2-year follow up.
Binge Eating Scale (BES), change at 2-year follow up
The patient reported outcome measurements (PROMS) eating behavior at baseline, 3 months, 6 months, 1 year and 2 years. The Binge Eating Scale comprise 16 items assessing binge eating problems. Additive scores range between 0-46, with higher scores indicating greater problems. Cut-off scores have been established to determine binge severity, with "severe" represented by scores \> 27, "moderate" by scores 18-26, and "mild-none" by scores \< 17.
Time frame: Changes from baseline BES at 2-year follow up.
The Power of Food scale (PFS) change at 2-year follow up
The patient reported outcome measurements (PROMS) eating behavior at baseline, 3 months, 6 months, 1 year and 2 years. The Power of Food scale assess both the psychological impact and respondent's responsiveness to a food-abundant environment. This is a 15-item scale whose items pertain to three situations: food being readily available in the environment but not physically present, food is physically present, but not tasted, and food is first tasted but not already consumed. The three subscales is scored 0-100 with higher scores indicating greater eating problems.
Time frame: Changes from baseline PES at 2-year follow up.
Weight change at 1-year follow up
Effect of intensive treatment on weight loss changes after 1- year follow up Body weight was measured with patients wearing light clothing and no shoes on Scanvaegt DS-530 (Århus, Denmark) at baseline and at 1-year follow up.
Time frame: Changes from baseline body weight at 1-year follow up.
Three Factor Eating Questionnaire (TFEQ - R21)
The patient reported outcome measurements (PROMS) eating behavior at baseline, 3 months, 6 months, 1 year and 2 years. TFEQ-R21 consists of 21 questions that measure cognitive and emotional conditions related to food intake, as well as degree of control over food intake. Each item scores either 0 or 1 point.
Time frame: Changes from baseline TFEQ-R21 at 2-year follow up.
