Abstract
Obesity and its associated comorbidities place a substantial burden on public health. Given the considerable potential of brown adipose tissue in addressing metabolic disorders that contribute to dysregulation of the body's energy balance, this area is an intriguing avenue for research. This study aimed to assess the impact of various polymers, including collagen type I, fibronectin, laminin, gelatin, gellan gum, and poly-l-lysine (PLL), on the in vitro brown adipogenic differentiation of dedifferentiated fat cells within a fibrin gel matrix. The findings, obtained through RT-qPCR, immunofluorescent imaging, ELISA assay, and mitochondria assessment, revealed that PLL exhibited a significant browning-inducing effect. Compared to fibrin-only brown-like drops after two weeks of incubation in brown adipogenic medium, PLL showed 6 (±3) times higher UCP1 gene expression, 5 (±2) times higher UCP1 concentration by ELISA assay, and 2 (±1) times higher mitochondrial content. This effect can be attributed to PLL's electrostatic properties, which potentially facilitate the cellular uptake of crucial brown adipogenic inducers such as the thyroid hormone, triiodothyronine (T3), and insulin from the induction medium.

Abstract
PURPOSE Dinner-bedtime interval was reported to be associated with general obesity. However, the association between dinner-bedtime interval and abdominal obesity is still unclear. This study was conducted to investigate the association of dinner-bedtime interval and abdominal obesity. METHODS A total of 7600 participants from Henan rural cohort study were included in this study. A standard questionnaire was used to obtain the time of dinner and sleep by the way of face-to-face interview. Sleep quality of each participant was evaluated by Pittsburgh Sleep Quality Index. Logistic regression and restricted cubic spline were used to assess the association between dinner-bedtime interval and abdominal obesity. Line regression was used to estimate the association between dinner-bedtime interval and lipid metabolism indexes. The mediation effect of sleep quality on the relationship between dinner-bedtime interval and abdominal obesity was evaluated. RESULTS In male, increased dinner-bedtime interval was associated with abdominal obesity risk (Adjusted OR: 1.084, 95% CI 1.009-1.164). Compared with participants with dinner-bedtime interval ≤ 2 h, those dinner-bedtime interval > 2 h had an elevated risk of abdominal obesity (Adjusted OR: 1.199, 95% CI 1.009-1.425). In addition, a positive linear dose-response relationship was detected between dinner-bedtime interval and abdominal obesity. Moreover, total cholesterol concentration increased by 0.047 mmol/L for each 1-h increase in dinner-bedtime interval (P = 0.019). In addition, sleep quality mediated 11.45% of the relationship between dinner-bedtime interval and abdominal obesity (adjusted mediation effect: - 0.010, 95% CI - 0.019 to - 0.003). But in female, these associations were not significant. CONCLUSION It is suggested that increased dinner-bedtime interval was related to a higher risk of abdominal obesity in rural China and this association was differed by sex. LEVEL OF EVIDENCE Level V: cross-sectional descriptive study.

Abstract
Fundamento: Evidências apontam variáveis antropométricas e de condicionamento físico como fatores associados à pressão arterial infantil. Analisá-los em apenas um contexto é um meio relevante de identificar o peso que cada um deles pode apresentar no desenvolvimento da hipertensão arterial. Objetivo: Identificar as possíveis associações de medidas antropométricas, da composição corporal, da atividade física moderada-vigorosa (AFMV) e da aptidão cardiorrespiratória (ApC) com a pressão arterial em crianças. Métodos: Estudo correlacional com abordagem quantitativa. Duzentos e quinze (215) estudantes com idades de 6 a 12 anos de uma escola pública de Porto Alegre, selecionados por critério de conveniência. A pressão arterial foi aferida através de um esfigmomanômetro digital. Para o tratamento dos dados, os valores de pressão arterial sistólica e diastólica foram padronizados (escore Z) e somados. As variáveis testadas como preditoras foram: AFMV; Percentual de gordura (%G); Índice de massa corporal (IMC); Razão cintura/estatura (RCE); Maturação somática; ApC. Após a verificação dos parâmetros de normalidade, as associações brutas e ajustadas (para sexo, idade e maturação somática) foram testadas através de equações de regressão linear. Para as análises, foi considerado p < 0,05. Resultados: Três diferentes modelos indicaram os melhores conjuntos de fatores associados à pressão arterial padronizada: O Modelo 1 (R2 = 0,21) se constituiu das variáveis RCE (β = 9,702) e AFMV (β = – 0,021); O Modelo 2 (R2 = 0,19) foi composto pelas variáveis IMC (β = 0,156) e AFMV (β = – 0,021); O Modelo 3 (R2 = 0,18) incluiu as variáveis %G (β = 0,063) e ApC (β = – 0,004). Conclusões: A pressão arterial de crianças é predita pelas variáveis corporais %G, IMC e RCE. Além disso, está associada negativamente à AFMV e a ApC.

Abstract
This study aims to analyze the behaviour of cardiac autonomic modulation in adolescents with a family history of hypertension along with polymorphism of the ACE gene (rs1799752). The study involved 141 adolescents, with a mean age of 14.89, divided into the following six groups: offspring of normotensive parents (ONP): DD, DI and II; and offspring of hypertensive parents (OHP): DD, DI and II. Blood pressure, body composition, family history of hypertension, sleep disorder, and sexual maturation were assessed for the groups' characterization. Afterwards, an electrocardiogram was performed, and oral mucosal cells were collected to analyze heart rate variability and genotypic research of angiotensin-converting enzyme. The main finding of this study was the decrease of vagal action in group OHP (genotype DD) relative to group ONP (genotype II): LF (%), 54.25 ± 3.14 vs 39.33 ± 3.80; HF (%), 45.74 ± 3.14 vs 60.66 ± 3.80; LF/HF, 1.48 ± 0.23 vs 0.68 ± 0.19. The results also showed changes in the variable diastolic blood pressure (DBP) in OHP (genotype DI) to ONP (genotype II) groups: 72.99 ± 2.33 vs 63.27 ± 1.72; and OHP (genotype DI) to ONP (genotype DD) groups. Adolescents with genotype DD and a family history of arterial hypertension present chances in cardiac autonomic modulation, the cardiac parasympathetic modulation is lower in these adolescents in comparison to participants of ONP + II group.

Abstract
The purpose of the present study was to examine the associations between body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), and high blood pressure (HBP), and to determine which anthropometric parameters can best predict HBP among Lithuanian adolescents aged 12–15 years. Data from the survey of “Prevalence and Risk Factors of HBP in 12–15-Year-Old Lithuanian Children and Adolescents (Study 1, 2010–2012)” were used; a total of 7,457 respondents (3,494 boys and 3,963 girls) were included in this analysis. Adolescents with BP above the 90th percentile were measured on two different occasions. Logistic regression analysis was used to assess the associations and to calculate odds ratios. Receiver operating characteristic (ROC) curve analysis was used to evaluate the predictive ability of the three anthropometric parameters to predict HBP. The adjusted odds ratios (aOR) in the highest quartiles of BMI, WC, and WHtR were statistically significant for both sexes separately (reference group – the first quartile): in boys, prehypertension – 4.91, 4.09, and 1.59; hypertension – 7.96, 6.44, and 2.81; and prehypertension/hypertension – 6.85, 5.65, and 2.37, respectively; and in girls, prehypertension – 3.42, 2.70, and 1.66; hypertension – 5.71, 3.54, and 2.90; and prehypertension/hypertension – 4.62, 3.17, and 2.31, respectively). According to the analyses of the ROC curve, BMI z-score provided the largest area under the curve (AUC) value, followed by WC z-score, while WHtR z-score showed the lowest AUC value in predicting elevated BP in both sexes separately. Among Lithuanian adolescents aged 12–15 years, both anthropometric indices – BMI and WC (but particularly BMI) – showed stronger associations with HBP and were better for the prediction of HBP, compared to WHtR.

Abstract
PURPOSE To compare the impact of adhering to a Mediterranean diet plus mixed physical exercise program (Move-It) implemented by means of printed instructions or via a web-platform (with or without e-mail support) on body composition, physical fitness, and blood pressure. DESIGN AND METHODS Randomized clinical trial. Fifty-two overweight or obese Spanish children and adolescents were randomly assigned to the print-based (n = 18), Move-It (n = 18), or Move-It plus support (n = 16) intervention groups. Two-way mixed ANOVA tests were used to compare any changes between the groups in terms of percentage body fat, physical fitness (VO2peak), handgrip strength, and systolic and diastolic blood pressure. The measurements were taken before and after a three-month mixed-exercise (aerobic and resistance) and Mediterranean-diet program which was either implemented by means of printed instructions or via a web-platform (with or without e-mail support). RESULTS No statistical differences were found between groups. However, the results highlighted significant improvements in body fat percentage metrics over time for all three groups (print-based: -1.8%, 95%CI -3.3% to -0.3%; Move-It: -1.8%, 95%CI -3.3% to -0.3%; Move-It plus support: -2.0%, 95%CI -3.7% to -0.4%, P < 0.05). We also observed a tendency towards improvement in the VO2peak, handgrip strength, and blood pressure variable values 10 min after the exercise-stress test in these three groups. CONCLUSIONS The program improved the body composition, regardless of the way it is implemented. PRACTICE IMPLICATIONS A mixed physical exercise program lasting for three months, combined with a Mediterranean diet, improves the body composition of children and adolescents with overweight/obesity.

Abstract
OBJECTIVE To investigate whether breastfeeding in early life affects blood pressure of preschoolers. METHODS Cross-sectional study nested in a cohort from a municipality in the state of Minas Gerais, Brazil. All children in the cohort were invited for this study. Thus, between 2009 and 2010, blood pressure of 230 preschool children and their mothers, in addition to anthropometric variables, previous history, and socioeconomic status were evaluated. Blood pressure measurement was assessed in the morning, using automatic Omron® HEM-714INT and HEM-781INT devices to measure the blood pressure of preschool children and their mothers, respectively. Logistic regression was used to study the association between breastfeeding and blood pressure. The significance level was set at 5%. RESULTS This study identified 19 (8.26%) preschool children with high blood pressure (values above the 90th percentile). High systolic blood pressure was associated with low birth weight (OR=5.41; 95% CI=1.45-20.23) and total breastfeeding duration of less than six months (OR=4.14; 95% CI=1.40-11.95). High diastolic blood pressure was not associated with any variable, whereas high systolic blood pressure/diastolic blood pressure ratio was associated with breastfeeding duration of less than six months (OR=3.48; 95% CI=1.34-9.1). CONCLUSION The results of this study indicate that preschoolers breastfed for a period of less than six months were more likely to have high blood pressure when compared to those breastfed for a longer period, suggesting a protective effect of breastfeeding against high blood pressure in this population.
