Sumario: Introduction: The term social vulnerability has been widely used in academic literature in recent years, not always with the same meaning, but it is quite polysemic. Thus, adolescents, regardless of social class, have suffered from the changing lifestyle habits of the modern world. The acquisition of sedentary behaviors (SB) and reduced levels of physical fitness in adolescents have a direct impact on the increased prevalence of various morbidities, including obesity, diabetes mellitus and hypertension. However, the literature still has limited information about the relationship between the inflammatory process and low physical fitness in children and adolescents in situations of social vulnerability. Objective: The current study aimed to investigate physical fitness and its relationship with inflammatory biomarkers in socially vulnerable adolescents from the Metropolitan Region of Vitória, Espírito Santo. Methods: The sample consisted of adolescent students of both sexes, aged between 16 and 17, enrolled in the 2023 school year. Body composition was assessed using an In Body 270 bioimpedance device. The diagnosis of Diabetes Mellitus and the lipid profile was carried out using fasting blood samples and biochemical analysis of serum concentrations of glucose (GL), total cholesterol (TC), triglycerides (TG) and high-density lipoprotein (HDL) and low-density lipoprotein (LDL). Blood pressure behavior was also determined. Cardiorespiratory fitness was measured using the 6-minute walk/run test and physical performance using the following tests: 20-meter run test, 4X4 meter square test, horizontal throw with medicine ball and horizontal jump. Inflammatory biomarkers were analyzed using blood samples of tumor necrosis factor (TNF-) and interleukins 6 and 10 (IL-6 and 10). The association between cardiorespiratory fitness parameters, physical performance and interleukins was analyzed using Pearson's correlation test. Results: Considering the anthropometric characteristics, the results show that height, body and muscle mass were higher in male adolescents when compared to females. However, fat mass and fat percentage were reduced in the male students. In addition, results showed that 11% of the schoolchildren were classified as overweight and 9% as obese when analyzing body mass index. The students had desirable levels of glucose, TC, HDL, LDL and TG. The systolic blood pressure values were higher in male adolescents than in female students (4%). As for the findings of the 6-minute walk test, the results show that the average distance was greater in male students than in girls, but both girls and boys had poor cardiorespiratory fitness (36%). The results of the physical fitness tests indicate that the boys performed better than the girls. The levels of IL-6 and IL-10 were similar between the groups. There was no correlation between the distance obtained in the physical fitness test, physical performance and inflammatory variables (IL-6 and IL-10). Conclusion: Physical fitness of schoolchildren in situations of social vulnerability is low, but itis not associated with inflammatory biomarkers.
