Item Adductor pollicis muscle thickness in Brazilian adolescents and associations with nutritional status, sexual maturation and physical activity (EVA-JF Study).(2022) Pereira, Priscila Moreira de Lima; Neves, Felipe Silva; Fontes, Vanessa Sequeira; Campos, Angélica Atala Lombelo; Coelho, George Luiz Lins Machado; Faria, Eliane Rodrigues de; Netto, Michele Pereira; Oliveira, Renata Maria Souza; Cândido, Ana Paula CarlosObjective: The present study aims to assess the associations of adductor pollicis muscle thickness (APMT) with age, skin color, sexual maturation, anthropometric indicators and physical activity in Brazilian adolescents. Materials and methods: Cross-sectional study of adolescents aged 14-19 years. Weight, height, body mass index (BMI), arm circumference (AC), APMT, body fat, fat-free mass (FFM), fat-free mass index (FFMI), sexual maturation, time of physical activity and skin color were evaluated. APMT was associated with categorical variables using Mann-Whitney or Kruskal-Wallis tests and correlated with anthropometric variables using Spearman’s correlation. Linear regression was used with APMT as a dependent and the other variables as predictors. Data analysis was carried out in SPSS® software (version 17.0) with a 5% significance level. Results: 828 adolescents were evaluated, 57.6% female, with a mean age of 16.13 ± 1.20 years. APMT had an average value of 18.0 mm in females and 21.0 mm in males. The measure was greater in males, in more advanced stages of sexual maturation, overweight and physical activity. It presented a moderate correlation with FFM, FFMI, body fat and AC. In the final model of multiple linear regression for females, the variables AC and body fat explain 20.1% of the APMT variability. For men, the variables AC and FFMI explain 30.5% of the APMT variability. Conclusion: It is recommended that APMT be used in a complementary manner in the nutritional assessment of adolescents.Item Analysis of the chemerin and resistin adipokines in children and adolescents.(2020) Fontes, Vanessa Sequeira; Mateus, Kácia; Netto, Michele Pereira; Oliveira, Renata Maria Souza; Coelho, George Luiz Lins Machado; Cândido, Ana Paula CarlosOBJECTIVES: To compare the serum concentrations of adipokines resistin and chemerin in children and adolescents with eutrophic and overweight and to evaluate their relationship with anthropometric, biochemical, and blood pressure variables. METHODS: a cross-sectional epidemiological study was conducted with 234 students enrolled in public elementary schools in the city of Juiz de Fora / MG. Anthropometric evaluation, biochemistry, and blood pressure measurement were performed. Statistical analyzes included the Student-t or Mann-Whitney tests, Pearson or Spearman correlation, used according to the distribution of the variables, and linear regression analysis, by means of the evaluation of the effect of the independent variables on the serum levels of chemerin and resistin, adjusted for age and sex. For the data analysis, SPSS® software version 21.0 and STATA® version 10.1 were used, assuming a significance level of 5%. RESULTS: the concentrations of chemerin were higher in eutrophic individuals than in those with excess weight (p> 0.05). In contrast, levels of resistin were higher in the young with excess weight than in the eutrophic ones (p <0.05). . In the multiple linear regression analysis, the levels of chemerin were associated with the values of resistin, systolic, and diastolic blood pressure. Resistance levels maintained association only with BMI and chemerin values. CONCLUSION: the adipokines analyzed presented a distinct profile in the groups of children and adolescents with eutrophic and overweight.Item Percentage of energy contribution according to the degree of industrial food processing and associated factors in adolescents (EVA-JF study, Brazil).(2021) Melo, Adriana Soares Torres; Neves, Felipe Silva; Batista, Aline Priscila; Coelho, George Luiz Lins Machado; Sartorelli, Daniela Sales; Faria, Eliane Rodrigues de; Netto, Michele Pereira; Oliveira, Renata Maria Souza; Fontes, Vanessa Sequeira; Cândido, Ana Paula CarlosObjective: To evaluate energetic contribution according to the degree of industrial food processing and its association with sociodemographic, anthropometric, biochemical, clinical and behavioural characteristics in adolescents. Design: Cross-sectional study (Adolescent Lifestyle Study). Food consumption was assessed using 24-h dietary recalls, with foods classified by degree of industrial progressing. The usual diet was estimated using the Multiple Source Method. In a linear regression model, the energy percentage (E %) was associated with sociodemographic, anthropometric, biochemical, clinical and behavioural characteristics, after adjustment for sex and age. Setting: Juiz de Fora, Brazil. Participants: Eight hundred and four adolescents, of both sexes, 14–19 years of age, enrolled in public schools. Results: The E % of unprocessed or minimally processed foods corresponded to 43·1 %, processed foods to 11·0 % and the ultraprocessed foods to 45·9 %. E % of unprocessed foods was associated with socio-economic stratum (adjusted β = −0·093; P = 0·032), neck circumference (adjusted β = 0·017; P = 0·049), screen time (adjusted β = −0·247; P = 0·036) and HDL-cholesterol (adjusted β = −0·156; P = 0·003). E % of ultraprocessed foods was associated with socio-economic stratum (adjusted β = 0·118; P = 0·011), screen time (adjusted β = 0·375; P = 0·003), BMI (adjusted β = −0·029; P = 0·025), neck circumference (adjusted β = −0·017; P = 0·028) and HDL-cholesterol (adjusted β = 0·150; P = 0·002). Conclusions: There was a high E % of ultraprocessed foods in the diet of the adolescents. Actions are needed to raise the awareness of adopting healthy eating habits.
