This study aimed to identify dietary patterns of adolescents, assess indicators of subclinical inflammation, and discover protective factors associated with the inflammatory process.
This study aimed to identify the dietary patterns (DPs) of adolescents and assess indicators of subclinical inflammation. It was a cross-sectional study aligned with the RPS cohort with data from Sao Luis, Maranhao, Brazil. We evaluated 511 adolescents between 18-19 years old. DPs were identified with a factor analysis of the principal components. Nutritional status was assessed with body mass index and body fat percentages. Hierarchical modeling was performed using a linear regression to estimate the beta coefficient (beta) of the independent variables with the dependent variables interleukin-6 and high-sensitivity C-reactive protein (hs-CRP). Five DPs were identified: energy-dense, sugar-sweetened beverages and breakfast cereals, prudent, traditional Brazilian and alcoholic and energy beverages. Greater adherence to the prudent DP was associated with a lower concentration of interleukin-6 (beta = -0.11; p value = 0.040). Greater adherence to the DP traditional Brazilian and alcoholic and energy beverages were associated with increased IL-6, mediated by the nutritional status. A higher BMI (beta = 0.36; p value = <0.001) and %BF (beta = 0.02; p value = 0.014) were associated with higher hs-CRP concentrations. The nutritional status and prudent pattern were associated with inflammatory biomarkers. These findings show that a higher consumption of fresh and minimally processed foods and the adequacy of the nutritional status are protective factors for the inflammatory process.
