Introduction: Considering the role of diet in modulating the inflammatory response, the Dietary Inflammatory Factor (DIF) was proposed to classify the inflammatory potential of the individuals’ diet.
Objective: To evaluate the relationship of the DIF with anthropometric indicators of obesity in workers of a metallurgical industry.
Methods: A cross-sectional study was carried out with 296 men, and anthropometric and food consumption data were collected, applying two dietary reminders. The values of Body Mass Index (BMI), Waist Circumference (WC), Waist-Hip Ratio (WHR), Waist-To-Height Ratio (WHtR) and Body Fat Percentage (% G) were used. The DIF was calculated by the IF Rating System software. We used the Shapiro Wilk, Spearman and Mann-Whitney correlation tests, adopting a significance level of 5%.
Results: The DIF was directly related to all anthropometric indicators of obesity: body mass index (p = 0.0001), waist circumference (p = 0.0004), waist hip ratio (p = 0.0003), waist to height ratio (p = <0.001) and percentage of body fat (p = <0.001). The obese participants presented the highest values of FID, characterizing the diet as more anti-inflammatory than that of non-obese individuals.
Discussion: A study conducted with adult men confirms the prevalence of overweight in this group. A pro-inflammatory diet is related to high rates of global and abdominal obesity. Not only the calories, but the inflammatory potential of feeding may be a future approach to weight maintenance
Conclusions: The findings reinforce the importance of developing actions to promote healthier dietary practices in the group, with a view to improving the inflammatory profile of the diet and reducing obesity in the group studied.
