VISCERAL FAT IS INCREASED IN INDIVIDUALS WITH CROHN'S DISEASE: A COMPARATIVE ANALYSIS WITH HEALTHY CONTROLS.

BACKGROUND
It is known that obesity is associated with a chronic inflammatory state, but few studies have evaluated visceral fat (VF) content and its role in individuals with Crohn's disease (CD).


OBJETIVE
To compare the nutritional status, body composition and proportion of VF between CD individuals and healthy volunteers.


METHODS
Cross-sectional study that enrolled individuals with Crohn's disease and healthy controls. The stratification according to nutritional status was carried out by means of BMI. The percentage of body fat percentage (%BF) and VF were estimated by means of DEXA. VF proportion was evaluated by means of the VF/BMI and VF/%BF ratios.


RESULTS
A total of 78 individuals were included. The control group was comprised of 28 healthy subjects aged 35.39±10 years old (60.7% women); mean BMI=23.94±3.34 kg/m2; mean VF=511.82±448.68 g; mean CRP=0.81±1.78 ng/mL. The CD group was comprised of 50 patients; 11 (22%) were underweight (BMI=18.20±1.97 kg/ m2; %BF=24.46±10.01; VF=217.18±218.95 g; CRP=4.12±4.84 ng/mL); 18 (36%) presented normal weight (BMI=22.43±1.48 kg/m2; %BF=30.92±6.63; VF=542.00±425.47 g and CRP=4.40±1.78 ng/mL); 21 (42%) were overweight or obese (BMI=29.48±3.78 kg/m2; %BF=39.91±7.33; VF=1525.23±672.7 g and CRP=1.33±2.06 ng/mL). The VF/BMI ratio was higher in the CD group when compared to controls (32.41±24.63 vs 20.01±16.23 g per BMI point; P=0.02). Likewise, the VF/%BF was also higher in the CD group (35.21±23.33 vs 15.60±12.55 g per percentage point; P<0.001).


CONCLUSION
Among individuals with Crohn's disease, BMI presents a direct correlation with visceral fat content. These results indicate the presence of an adiposopathy in Crohn's disease subjects, which is evidenced by a higher visceral fat.
