Conditions
Binge-Eating Disorder

Device: High intensity bright light therapy
Registration Number
NCT03094260
Lead Sponsor
Hospices Civils de Lyon
Brief Summary

Binge Eating Disorder (BED) is the most widespread food behavior disorder, with prevalence three times higher than anorexia. Its pathophysiology remains poorly understood and the investigators have few therapeutic options. Following a review of the literature, the investigators hypothesize that luminotherapy could be an innovative treatment of BED by its favorable effect on triggers of hyperphagic access, circadian disturbances, attention and impulsivity. The study is prospective, interventional, randomized, double-blind, monocentric (HCL). 52 patients with BED will be randomized to an active arm with intensive luminotherapy (1 daily 30 min, 10,000 lux in the morning) versus a placebo arm (\<500 lux). Treatment will be delver every day during 30 days. Assessments will take place on D0, D30 and D60. The main objective is to compare the evolution of the number of hyperphagic access before and after treatment between the two groups. Secondary objectives are to compare characteristics of hyperphagic access, bodily concerns, food dependence and impulsivity, mood, anxiety, cognitive and attentional profiles (STROOP, Go / No Go, SST, BART, Prospective Time Estimation Task, Switching Task), liking / wanted for different food categories and carbohydrate metabolism (CRP, glucose, insulinemia, insulin resistance, profile of lipid abnormalities, 25-OH vitamin D3).

Primary Outcome Measures
NameTimeMethod
Comparison of the number of hyperphagic access, over 7 consecutive days, before starting therapy with light therapy and discontinuation of treatmentDay-7 to Day-1 period (before Day 0) compared to Day23 to Day30 period (after Day 0)

The number of hyperphagic access will be determined using a crisis agenda filled out by patients each day

Secondary Outcome Measures
NameTimeMethod
Characteristics of hyperphagic access (duration of crisis)Day 60

Evaluation of the duration,by the crisis agenda.

Characteristics of hyperphagic access (severity of the disorder)Day 60

Evaluation of the severity of bulimic hyperphagia by the Bing Eating Scale.

Characteristics of hyperphagic access (severity of the disorder, duration of crisis, amount of food ingested and evolution of factors triggering)Day 30

Evaluation of the severity of bulimic hyperphagia by the Bing Eating Scale. Evaluation of the duration, the quantity of food ingested during the hyperphagic access and the delays between two accesses by the crisis agenda. Evaluation of the factors triggering by the "START" scale.

Comparison of the number of hyperphagic access, over 7 consecutive days, before starting therapy with light therapy and 30 days after discontinuation of treatmentDay-7 to Day-1 period (before Day 0) compared to Day53 to Day60 period (after Day 0)

The number of hyperphagic access will be determined using a crisis agenda filled out by patients each day

Characteristics of hyperphagic access ( evolution of factors triggering)Day 60

Evaluation of the factors triggering by the "START" scale.

Evolution of attentional cognitive profiles and impulsivityDay 60

The evolution of attentional and impulsive cognitive profiles will be measured from a computerized neurocognitive test battery whose order will be randomly fixed. The tests will be STROOP, The Go / No Go, The Stop Signal Task, The Balloon Analog Risk Task, The Prospective Time Estimation Task, The Set Switching Task

Characteristics of hyperphagic access (amount of food ingested )Day 60

Evaluation of the quantity of food ingested during the hyperphagic access and the delays between two accesses by the crisis agenda.

Symptomatic development of BEDDay 60

The symptomatic development of BED will be measured by evaluating the composite:

* The psychopathology of the BED from the Eating Disorder Inventory 2 questionnaire

* The Body concerns based on the "Body sharpe" questionnaire

* The Addiction to food from the Yale Food Addiction scale

* The Diet-related impulsivity from the Three-Factor Eating Questionnaire

Evolution of other psychological parameters related to BEDDay 60

The evolution of other psychological parameters will be measured by evaluating the composite mood from the Beck Depression Inventory scale, the anxiety from the "State Trait Anxiety Inventory or STAI-Y" scale, the clinical impulsivity from the "UPPS-P shortcut" scale

Evolution of appetite for different categories of foodDay 60

The evolution of appetite for different categories of food will be measured from a computerized task: the Leed Food Preference Questionnaire (LFPQ). A description of the test is available at: https://www.millisecond.com/download/library/

Biological parameters may be impacted or mediated by part of the treatment efficiencyDay 30

Inflammation parameters, glucose, insulinemia, insulin resistance, Profile of lipid abnormalities, 1-25-OH vitamin D3

Weight (kilogramm)Day 60

Weight will be expressed in absolute value

Observance rate to light therapyday1 to day30

The assessment of the adherence rate will be quantified by the average number of lux received over the 30 days of treatment. The exposure (expressed in lux number / session) in lux will be measured and recorded using a luxmeter
