Purpose: 1 - To study the visceral fat (VF) and parameters of obesity in the diverticular disease of the colon (DDC). 2 - To analyze the consumption of fat in DDC.
Methods: Study of unselected medium-risk subjects who underwent colonoscopy for screening of colorectal cancer during 1 year. Subjects were inquired by a nutritionist about nutritional habits. We evaluated anthropometric variables and fat mass by impedance. Visceral fat (VF) and subcutaneous fat (SF) were assessed by ultrasound by the same gastroenterologist. Statistics: Chi-square, t test, odds ratio (OR).
Results: Included 305 individuals, 46.9% female, mean age 60±6.6 years. Sixty-four (21%) individual had DDC. There was a significant difference for age (p<0.01), visceral fat (p<0.01), waist circumference (p<0.01), hip circumference (p=0.03), total fat (p=0.01) and monounsaturated fat consumption (p<0.01). The probability of occurrence of DDC was higher in the 3rd tertile of age (OR 3.1, 95% CI 1.5-6.5), visceral fat (2.3 OR, 95% CI 1.02-5.2) and total fat intake (OR 4.1, 95% CI 1.1-14.6) than in 1st tertile. There was no significant difference for sex, BMI, GS, fat mass (total and %), fiber intake, consumption of alcohol and caffeine.
Conclusion: 1. Visceral fat was a risk factor for the occurrence of DDC. 2. The intake of dietary fat correlated positively with the DDC.
