---|---|
Active Comparator: Crohn's Disease (CD) Control Group
Participants will receive only the one time standard of care in-clinic diet counseling at visit 1.
|
Standard of care diet counseling provided at clinic visit 1.
|
Experimental: Experimental CD Low Fat Diet (LFD) Group
Participants will be provided catered LFD meals for 8 consecutive weeks consisting of daily breakfast, lunch, dinner and snacks.
|
Daily breakfast, lunch, dinner and snacks LFD catered meals.
Meals will have approximately 20% calories from fat, a goal ratio close to 1:1 omega-6/omega-3 fatty acids, and approximately 25-35 grams of fiber per day.
|
Experimental: Experimental CD LFD + DPS Group
Participants and one family member that lives with them will be provided catered LFD meals for 8 consecutive weeks consisting of daily breakfast, lunch, dinner and snacks.
In addition, the participant and their family member will receive 12 consecutive weeks of Dyadic Psychological Support (DPS).
|
Daily breakfast, lunch, dinner and snacks LFD catered meals.
Meals will have approximately 20% calories from fat, a goal ratio close to 1:1 omega-6/omega-3 fatty acids, and approximately 25-35 grams of fiber per day.
The dyadic psychosocial support (DPS) intervention will be provided for a total of 12 weeks.
The 12-week DPS intervention consists of eight sessions (main sessions) and two booster sessions.
The intervention will incorporate psychoeducational components that combine didactic and behavioral regulatory procedures to promote healthy diet behavior for self-determined reasons.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in fat intake
Time Frame: Baseline, 8 weeks
|
Change in daily fat intake calculated through patient reported diet diary app Nutrihand.
|
Baseline, 8 weeks
|
Rate of adherence to fat intake
Time Frame: Week 36
|
Adherence to fat intake is measured by the web-based Automated Self-Administered 24-hour diet recall (ASA24).
|
Week 36
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in clinical symptoms as assessed by Patient Reported Outcomes (PRO2).
Time Frame: Baseline, Week 8
|
PRO2 is the sum of the average daily stool frequency and abdominal pain.
A weighted total PRO2 score of less than 75 is an indication of remission.
|
Baseline, Week 8
|
Change in clinical symptoms as assessed by the Harvey Bradshaw Index (HBI)
Time Frame: Baseline, Week 8
|
HBI is a 5-item questionnaire.
An HBI score of <5 indicates remission, 5-7 indicates mild disease, 8-16 indicates moderate disease and >16 indicates severe disease.
|
Baseline, Week 8
|
Change in clinical symptoms as assessed by the Short Crohn's Disease Activity Index (sCDAI).
Time Frame: Baseline, Week 8
|
sCDAI is the sum of the average daily stool frequency, general well-being and abdominal pain.
A weighted total sCDAI score of less than 150 indicates remission, 150-219 indicates mild activity, 220-450 indicates moderate activity and > 450 indicates severe activity.
|
Baseline, Week 8
|
Change in quality of life (QoL) as assessed by the Short Inflammation Bowel Disease Questionnaire (sIBDQ).
Time Frame: Baseline, Week 8
|
sIBDQ is a 10-item shortened version of the original IBDQ assessing QOL with total scores ranging from 1 to 7 with a higher score indicating a better QOL.
|
Baseline, Week 8
|
Change in quality of life (QoL) as assessed by the Patient-Reported Outcomes Measurement Information System (PROMIS-29).
Time Frame: Baseline, Week 8
|
The PROMIS-29, a generic health-related quality of life survey, assesses each of the 7 PROMIS domains with 4 questions.
The questions are ranked on a 5-point Likert Scale.
There is also one 11-point rating scale for pain intensity.
A score of 50 represents the mean or average of the reference population.
A score of 60 means that the person is one standard deviation above the reference population (standard deviation = 10).
|
Baseline, Week 8
|
Change in the expression of cytokine high-sensitivity C-reactive protein (hsCRP).
Time Frame: Baseline, Week 8
|
Change in the expression of cytokine high-sensitivity C-reactive protein (hsCRP) evaluated in mg/L.
|
Baseline, Week 8
|
Change in the expression of Serum Amyloid A (SAA).
Time Frame: Baseline, Week 8
|
Change in the expression of SAA evaluated in pg/mL.
|
Baseline, Week 8
