Tri-Ponderal Mass Index (TMI)- A Reliable Anthropometric Indices for Early Screening of Adolescent Obesity in a School-Based Setting: A Cross-Sectional Study

ObjectiveThis study aimed to examine the reliability of Tri-Ponderal Mass Index (TMI) for early screening of adolescent obesity in comparison to anthropometric measures such as hip-circumference, neck-circumference, waist-circumference, waist-height-ratio, waist-hip-ratio, and body mass index. MethodsA school-based, cross-sectional study was conducted between July-December 2019 among 1101 school-going adolescents (both genders), aged 12 to 17 years in Rudrapur city of Uttarakhand. Data on anthropometric measurements was collected by using well calibrated equipment's, and age- and gender-specific BMI percentile cut-off values recommended by the Indian Academy of Pediatrics (IAP) were used to define the overweight and obesity. Statistical analysis was done using SPSS software version 16.0. Receiver operating characteristic (ROC) curve analysis was conducted, and optimal cut-off values for anthropometric measurements were determined using the Youden Index (sensitivity + specificity -1). ResultsOut of 1101 study participants 71.5% (n=787) and 28.5% (n=314) were boys and girls, respectively. The prevalence of overweight and obesity amongst adolescents was 10.4% and 4.1%, respectively. ROC curve analysis was conducted and TMI exhibited the highest Youden index both in terms of overweight (0.835) and obesity (0.869) among adolescents. The optimal TMI cut-off values for overweight and obese boys and girls were determined to be >12 kg/m³ and >14 kg/m³; >13 kg/m³ and >16 kg/m³, respectively. TMI demonstrated superior predictive capacity for early screening of adolescent obesity, as indicated by high discriminative power, sensitivity, and specificity. ConclusionsTMI can be used as the simple reliable screening tool for early screening of overweight and obesity among adolescents.

THE EFFECTS OF 12 WEEKS BASIC GYMNASTICS EXERCISES ON BODY COMPOSITION AND LIPID PROFILES IN OBESE CHILDREN

Obesity is a major health concern in the world because it is associated with many diseases. It has been shown that basic gymnastics exercises effectively prevent and treat this problem. Therefore, the present study investigated the effect of 12 weeks of basic gymnastics exercises on body composition and lipid profile in obese girls. In this quasi-experimental study, with a design pre-test-post-test and a control group, 30 obese girls with Body Mass Index (BMI) at or above the 95th percentile and the average age of 9.4 years, were selected purposefully and were divided into 2 groups (Basic gymnastics training, and control) randomly. The training protocol was implemented for 12 weeks, three times a week, and 45 minutes for each session incrementally. Body composition and lipid profile indices were measured in two stages: pre-test and post-test. In order to analyze the data, multivariate covariance tests were used. The results of the study showed that the exercise intervention significantly reduced the fat percentage and BMI index in obese children (p≤0.001). In addition, a significant decrease in total cholesterol, triglyceride, and Low Density Lipoprotein Cholesterol (LDL-C) and a significant increase in High Density Lipoprotein Cholesterol (HDL-C) were observed (p≤0.002). These findings indicate the beneficial effects of basic gymnastics training on body composition and lipid profile in obese children. Therefore, the use of basic gymnastics training is recommended to improve these factors.

Sport participation, weight status, and physical fitness in French adolescents.

The primary objective of this study was to investigate the associations between sport participation and weight status with physical fitness among French adolescents. The secondary aim was to establish sex- and age-specific physical fitness percentiles for French adolescents. The sample comprised 8084 adolescents (4126 boys, 3958 girls), aged 10-14years. Participants were tested on cardiorespiratory fitness and muscular strength using the following tests: 20-m shuttle run test and handgrip strength test. A questionnaire on organized sport participation was completed. Physical fitness levels were better in boys (P < 0.005). Handgrip strength increased with age whereas 20-m shuttle run performance decreased with age. Overweight and obese adolescents had significantly lower cardiorespiratory fitness levels than their normal-weight peers (P < 0.005), whereas normal-weight adolescents had lower cardiorespiratory fitness than thin adolescents (P < 0.005). Sport participation was higher for boys (57.2% boys vs. 52.8% girls) (P < 0.001). Adolescents who participated in at least one organized sport (either through a club or at school) were fitter than those who did not participate in organized sports (P < 0.005). Adolescents who engaged in organized sports were more active and physically fit than those who did not participate. The fitness benefits of club sports are greater than those provided by school-based sports, highlighting the potential of sports clubs as a key setting for promoting health. What is Known: • Physical fitness is a strong marker of health in children and adolescents. • The last French Report Card highlighted the lack of fitness data and the need for nationwide programs, while showing a significant decline in cardiorespiratory fitness among youth in recent decades.. What is New: • This study reveals that adolescents participating in organized sports have better physical fitness compared to their peers who do not, emphasizing the potential advantages of club sports over school-based activities. • We highlight the need for targeted strategies, particularly for overweight or obese adolescents and girls, to increase participation in organized sports and enhance health outcomes. • The study emphasizes the need to develop policies that improve access to organized sports clubs and expand physical education in schools, aiming to improve CRF in adolescents.

Correlation of tri-ponderal mass index with insulin-like growth factor-I and insulin-like growth factor binding protein-3 in children and adolescents.

We aimed to investigate the relationship between the tri-ponderal mass index (TMI), a new indirect measure of fat mass, and insulin-like growth factor (IGF)-I/IGF binding protein (IGFBP)-3. The study included 1,630 children and adolescents who visited Jeonbuk National University Children's Hospital. Each patient's medical record was retrospectively reviewed for age, sex, height, weight, body mass index (BMI), TMI, and IGF-1 and IGFBP-3 levels. Study participants were divided by sex and then categorized by age, BMI, and TMI. Finally, the correlations of TMI with IGF-1 level, IGF-1 standard deviation score (SDS), IGFBP-3 level, IGFBP-3 SDS, and IGF-1/IGFBP-3 ratio were investigated. All participants were <19 years of age. BMI correlated with IGF-1 and IGFBP-3 levels in both sexes; however, the relationship with TMI differed by sex. TMI correlated with IGF-1 and IGFBP-3 SDS in boys and with IGF-1, IGFBP-3, and IGFBP-3 SDS in girls across all ages. In boys, BMI and TMI significantly correlated with IGF-1, IGF-1 SDS, IGFBP-3, IGFBP-3 SDS, and the IGF-1/IGFBP-3 ratio in the normal-weight group. TMI also correlated with IGF-1, IGFBP-3, and IGFBP-3 SDS in the overweight group. In girls, BMI significantly correlated with IGF-1, IGF-1 SDS, IGFBP-3, IGFBP-3 SDS, and the IGF-1/IGFBP-3 ratio in the normal-weight group and with IGFBP-3 and IGFBP-3 SDS in the overweight group, while TMI correlated with IGF-1, IGF-1 SDS, and the IGF-1/IGFBP-3 ratio in the normal-weight group; with IGF-1, IGFBP-3, and IGFBP-3 SDS in the overweight group; and with IGFBP-3 SDS in the obese group. TMI may more strongly correlate with IGFBP-3 level than BMI in overweight boys and with IGFBP-3 SDS in overweight and obese girls. The correlation of IGFBP-3 SDS with TMI may be helpful for evaluating weight status in adolescent girls.

Value of single-phase gonadotropin-releasing hormone stimulation test in diagnosis of central precocious puberty in girls with different levels of body mass index

To investigate the value of single-phase gonadotropin releasing hormone (GnRH) stimulation test in the diagnosis of central precocious puberty (CPP) in girls with different levels of body mass index (BMI). A retrospective analysis was performed for the data of 760 girls with breast development before 7.5 years of age who attended the Third Affiliated Hospital of Zhengzhou University from January 2017 to August 2023. According to the results of GnRH stimulation test and clinical manifestations, they were divided into a CPP group (297 girls) and a non-CPP group (463 girls). According to the values of BMI, the girls were divided into a normal weight group (540 girls), an overweight group (116 girls), and an obese group (104 girls). The receiver operating characteristic (ROC) curve was used to investigate the value of single-phase GnRH stimulation test in the diagnosis of CPP in girls with different levels of BMI. Luteinizing hormone (LH)/follicle-stimulating hormone at 30 minutes after GnRH stimulation had an area under the curve (AUC) of 0.985 in the diagnosis of CPP, which was higher than the AUC at 0, 60, and 90 minutes (P<0.05). LH at 30 minutes had a similar diagnostic value to LH at 60 minutes (P>0.05). LH at 30 minutes was negatively correlated with BMI and BMI-Z value (P<0.05).The AUC for diagnosing CPP in normal weight, overweight, and obese girls at 30 minutes LH was 0.952, 0.965, and 0.954, respectively (P<0.05). The 30-minute GnRH stimulation test has a good value in the diagnosis of CPP in girls with different levels of BMI and is expected to replace the traditional GnRH stimulation test, but the influence of BMI on LH level should be taken seriously.

The impact of interval training on adiponectin to leptin ratios and on blood pressures in severely obese adolescent girls: A randomized controlled trial

ABSTRACT Interval-training is widely implemented among populations with obesity to decrease metabolic-disorders; however, high-intensity-interval-training (HIIT) has rarely been studied in severely obese adolescent girls. Therefore, the aim of this study was to compare the effects of 8 weeks of (HIIT) or moderate-intensity interval-training (MIIT), on cardiometabolic risk factors and hormonal-ratios in severely-obese-girls. For this aim, 35 female-adolescents (14.4 ± 1.4 years) were assigned randomly into HIIT (n = 12) and MIIT (n = 12), groups and a control group (CG, n = 11). Both training groups significantly improved (p < 0.05): the body-mass, body-mass-index (BMIp95), body-fat (BF%), waist-circumference (WC), mean-arterial-pressure (MAP), with a slight increase in the HIIT group. However, HIIT induced greater improvements on the maximal oxygen uptake (VO2MAX) and the speed related (24.7 and 11.8%) compared to MIIT. Higher improvements occurred in HIIT group related to leptin and adiponectin concentrations and the A/L ratio at (p < 0.001). In conclusion, the findings indicate that both HIIT and MIIT can positively influence body composition and cardio-respiratory fitness. Given the significant correlation noted between the A/L ratio, BMIp95, BF%, and MAP post-HIIT, this training modality may be considered a more advantageous approach over MIIT for mitigating cardio-metabolic issues in severely obese adolescent girls.

Association between BMI and age at menarche or spermarche among both sexes: Findings from six successive national surveys in China.

To explore trends of the association between body mass index (BMI) and age at menarche or spermarche and its urban-rural disparities from 1995 to 2019. A total of 912 753 children and adolescents - including 519 940 9-18 years old girls and 392 813 11-18 years old boys - were involved in six successive cross-sectional surveys conducted across 30 provinces in China from 1995 to 2019. Data on menarche and spermarche was collected using the status quo method, where same-gender physicians conducted face-to-face interviews to determine if children and adolescents had experienced their first menstrual cycle or ejaculation (yes/no). The median age at menarche or spermarche was estimated by probit analysis. Anthropometric measurements measured the height and weight of the study subjects. Children and adolescents were classified into thinness, normal range of weight, overweight, and obesity. t test was used to compare the differences in BMI between premenarchal and postmenarchal girls or prespermarcheal and postspermarcheal boys. Logistic regression was used to explore the associations between BMI/nutritional status and menarche or spermarche stratified by urban or rural residency status. From 1995 to 2019, BMI in all age groups growth over time, and the values of BMI among children and adolescents under 15 who had menarche or spermarche were more significant than those without menarche or spermarche. In 2019, for girls, thinness was associated with delayed menarche (odds ratio (OR) = 0.26; 95% confidence interval (CI) = 0.24-0.28), while overweight (OR = 1.99; 95% CI = 1.85-2.14) and obesity (OR = 2.20; 95% CI = 1.92-2.53) was associated with advanced menarche. For boys, thinness was associated with delayed spermarche (OR = 0.71; 95% CI = 0.65-0.78), overweight was associated with advanced spermarche (OR = 1.08; 95% CI = 1.01-1.15) while obesity had no association with spermarche. The OR between BMI and menarche in 1995 was 1.35 (95% CI = 1.33-1.37), which decreased to 1.19 (95% CI = 1.18-1.20) by 2019. The OR between BMI and spermarche in 1995 was 1.10 (95% CI = 1.09-1.11), which decreased to 1.02 (95% CI = 1.02-1.03) by 2019. The trends by urban-rural stratification were consistent with the total sample. We have established a dose-response relationship between BMI and menarche in girls, whereas the association appears to be nonlinear in boys, and the associations were diminishing. Similar findings were observed in both urban and rural areas. Considering the dual adverse effects of obesity and early puberty on health, the results of this study suggest that sexual health education should be strengthened, especially among obese girls. Further research on the influencing factors and biological mechanisms of early puberty will be beneficial.

Genetic determinants of obesity in adolescent girls

Significant progress in understanding the genetic contribution in obesity and its prevalence at all ages has been achieved since existing methods of treatment and preventive measures aimed at combating obesity are not effective enough.Purpose. To study the prevalence of pathologic single nucleotide polymorphisms rs6265 of the brain neutrophic factor gene BDNF; rs1137101 of the leptin receptor gene LEPR; rs9939609 of the gene, associated with fat mass, FTO; rs4762 and rs699 of angiotensinogen AGT gene; rs1799883 of fatty acid transporter gene FABP2; rs1801282 of PPARG2 gene in obese adolescent girls.Material and methods. 72 teenage girls aged 12–17 years were examined. Group 1 consisted of 36 obese children (standard deviation coefficient SDS BMI ≥ 2.0), group 2 — 36 non-obese children (SDS BMI &lt;1.0). Anthropometric, molecular genetic, and statistical methods were used.Results. In obese adolescent girls, an association was detected with only one gene — PPARG2, a polymorphic locus (Pro/Pro). The prevalence rate of the C allele in group 1 was 80%, in group 2 — 3% (p&lt;0.05). No statistically significant differences in the frequencies of genotypes and alleles of other genes in children with obesity and normal body weight were established.Conclusion. Further large-scale studies, including biochemical and hormonal parameters, are needed to establish the influence of specific polymorphic loci of various genes contributing in obesity and metabolic processes.

Association between Thyroid Function and Insulin Resistance Indices in Korean Adolescents: Findings from the 2014-2015 Korea National Health and Nutrition Examination Survey.

This study investigated the sex-specific association between thyroid function and various insulin resistance (IR) indices, including noninsulin-based IR indices, in euthyroid adolescents. A total of 465 adolescents (aged 12-18 years; 255 boys and 210 girls) based on data from the 2014-2015 Korea National Health and Nutrition Examination Survey were included. Serum thyrotropin (thyroid-stimulating hormone [TSH]) and free thyroxine (fT4) were used to assess thyroid function, whereas the homeostasis model assessment of insulin resistance (HOMA-IR), quantitative insulin-sensitivity check index (QUICKI), glucose/insulin ratio (GIR), triglyceride-glucose (TyG) index, and triglyceride/high-density lipoprotein cholesterol (TG/HDL-C) ratio were used to assess IR. The relationship between thyroid function and IR was analyzed using multiple linear regressions stratified by sex, considering obesity status. The relationship between thyroid function and IR varied depending on sex and was more pronounced in the overweight/obesity subgroup for both boys and girls. In overweight and obese boys and girls, fT4 was significantly associated with HOMA-IR and QUICKI with conflicting association directions. TSH was also positively associated with the TyG index in both sexes. The findings suggest that the relationship between thyroid function and IR in adolescents might vary depending on sex, and the degree of association was significant in obese adolescents.

Small gut intestine microbiota in adolescent girls with obesity

Aim. To characterize the small intestine microbiome in adolescent girls with obesity according to gas chromatography-mass spectrometry of microbial markers (CMSMM). Material and Methods. The research involved 72 adolescents (girls) 12-17 years old, half of the children (group 1) were obese, the other half (group 2) were not obese, as well as did not have any chronic diseases. Microbial markers in blood samples were examined by the CMSMM method. In order to examine correlation between the small intestine microbiota and obesity, a logistic model was formed. ROC analysis was used to determine possible effects of microorganisms on obesity. Results. There were found significant differences in the small intestine microbiome of obese girls, and alike microbiocenosis of children with normal body weight. Obese adolescent girls had higher levels of Nocardia asteroides 504.14[296; 1015] cells/g×10⁵ and Candida spp 241.85[198.09;629.97] cells/g×10⁵. Microorganisms of the opportunistic flora such as Actinobacteria, Firmicutes, Proteobacteria and microscopic fungi, as well as herpesviruses were significantly deficient. Conclusions. Nocardia asteroides and Candida spp. are associated with obesity. The risk of obesity in adolescent girls increases with a growing number of above-mentioned microorganisms.

Not Only Metabolic Complications of Childhood Obesity.

The increasing incidence of obesity in the pediatric population requires attention to its serious complications. It turns out that in addition to typical, well-known metabolic complications, obesity as a systemic disease carries the risk of equally serious, although less obvious, non-metabolic complications, such as cardiovascular diseases, polycystic ovary syndrome, chronic kidney disease, asthma, thyroid dysfunction, immunologic and dermatologic conditions, and mental health problems. They can affect almost all systems of the young body and also leave their mark in adulthood. In addition, obesity also contributes to the exacerbation of existing childhood diseases. As a result, children suffering from obesity may have a reduced quality of life, both physically and mentally, and their life expectancy may be shortened. It also turns out that, in the case of obese pregnant girls, the complications of obesity may also affect their unborn children. Therefore, it is extremely important to take all necessary actions to prevent the growing epidemic of obesity in the pediatric population, as well as to treat existing complications of obesity and detect them at an early stage. In summary, physicians treating a child with a systemic disease such as obesity must adopt a holistic approach to treatment.

DIFFERENCES IN OBJECTIVELY AND SUBJECTIVELY MEASURED WEIGHT AND HEIGHT IN SLOVAK ADOLESCENTS

The goal of our contribution is the issue of differences in objectively and subjectively measured weight (and consequently Body Mass Index /BMI/) and height in Slovak adolescents. The data obtained are a part of international study Health Behaviour in School Aged Children (HBSC) performed in Slovakia in 2017/2018. Our representative sample consisted of 782 adolescents of the fifth to ninth grades of elementary schools in Slovakia in the target group of 11 to 15 years old. We also obtained objective somatic indicators by measuring and subjective indicators were obtained using 2 item questions of the HBSC questionnaire. The results obtained point to the fact, that adolescents tend to add height and decrease weight (boys on average 0.9 kg and girls 0.6 kg) by self-reported question. However, statistically significant difference was observed in weight difference among boys girls and in total. Overweight boys tend to take almost 3 kilograms of their weight. Moreover, obese boys tend to take 5.14 kilograms and obese girls 2.40 kilograms of their weight. The results of survey show that adolescents self- assessing their height and weight tend to increase their height and decrease their weight, which is more pronounced in boys than in girls. Acknowledgments: The document is also based on the support of the grant task of MS VVS SR: VEGA 1/0460/23: „Postural health in children and adolescents and the possibilities of influencing it “

Obesity and menstrual disorders in adolescent girls -is there a relationship?

The development of menstrual cycle disorders (MCD) in adolescent girls is often combined with obesity, therefore, it seems relevant to study the effect of pathological body weight gain on pubertal development. The purpose of the study. To study the association of obesity and menstrual disorders in adolescent girls. Materials and methods. Group 1 (40 people): obese and MCD, group 2 (40 people): with obesity without MCD. Laboratory tests: assessment of carbohydrate and lipid metabolism, calculation of the HOMA index; blood plasma levels of kisspeptin, thyroid-stimulating hormone (TSH), free thyroxine, total testosterone, prolactin, free androgen index (ISA), anti-muller hormone (AMH), 17-0H Progesterone(17-OHP), lutenizing hormone (LH), follicle stimulating hormone (FSH), estradiol (Е2). The obtained data were analyzed by constructing a mathematical model of the pathogenetic mechanisms associated with MCD in obese adolescent girls. Results. There were no differences in the degree of obesity in the groups: SDS BMI (Me1=2.9; Me2=2.94, p=0.459). In group 1, significantly more often: impaired glucose tolerance (1 g.=15%; 2 g.=2.5%, p=0.048) (NTU), hypertriglyceridemia (1 g.=37.5%; 2 g.=15%, p=0.048). Significantly higher in the group with MCD: levels of LH (Me1=8.85 mIU/ml; Me2=6.70 mIU/ml, p=0.022), kisspeptin (Me1=55.4 pg/ml; Me2=38.3 pg/ml, p=0.001), total testosterone (Me1=1.90 nmol/l; Me2=1.25 nmol/l, p=0.026), ISA (Me1=14.5; Me2=8.65, p=0.027), AMG (Me1=6.61 ng/ml; Me2=24.26 ng /ml, p=0.014), with a significantly lower level of Е2 (Me1=33.5 pg/ml; Me2=5.0 pg/ml, p=0.012). Conclusions. 1. Adolescent girls with obesity and MCD are significantly more likely to have NTU and hypertriglyceridemia compared with girls with similar severity of obesity without MCD; 2. When obesity and MCD are combined, significantly higher levels of kisspeptin, LH, AMH, total testosterone, ISA are noted; 3. Among the pathogenetic mechanisms associated with MCD, hormonal and matabolic independent associations have been established, the effect of which is independent; hormonal: kisspeptin - LH - testosterone, and metabolic: BMI - insulin and BMI - leptin.

Development and application of a nomogram model for predicting the risk of central precocious puberty in obese girls.

The purpose of this study is to develop and assess a nomogram risk prediction model for central precocious puberty (CPP) in obese girls. We selected 154 cases of obese girls and 765 cases of non-obese girls with precocious puberty (PP) who underwent the gonadotropin-releasing hormone stimulation test at the Jiangxi Provincial Children's Hospital. Univariate analysis and multivariate analysis were conducted to identify predictors of progression to CPP in girls with PP. A predictive model was developed and its predictive ability was preliminarily evaluated. The nomogram was used to represent the risk prediction model for CPP in girls with obesity. The model was validated internally using the Bootstrap method, and its efficacy was assessed using calibration curves and clinical decision analysis curves. In obese girls with PP, basal luteinizing hormone (LH) and follicular stimulating hormone (FSH) levels, as well as uterine volume, were identified as independent risk factors for progression to CPP. In non-obese girls, the basal LH level, bone age, and uterine volume were identified as independent risk factors for progression to CPP. With an AUC of 0.896, the risk prediction model for obese girls, was found to be superior to that for non-obese girls, which had an AUC of 0.810. The model displayed strong predictive accuracy. Additionally, a nomogram was used to illustrate the CPP risk prediction model for obese girls. This model performs well in internal validation and is well calibrated, providing a substantial net benefit for clinical use. A medical nomogram model of CPP risk in obese girls comprised of basal LH value, basal FSH value, and uterine volume, which can be used to identify those at high risk for progression of CPP in obese girls and develop individualized prevention programs.

Association between Body Mass Index and Depressive Symptoms among Adolescent Females in Baghdad, AlKarkh during 2022

Background: Due to their high prevalence rates, adolescent obesity and depression are among the most renowned public health concerns globally. Obesity is considered the leading cause of morbidity and death in Iraq in 2019. There is scarce research and surveys regarding the relationship between BMI and depression, especially in young Iraqi females. Objectives: To explore the level of depression among adolescent girls, and to determine its association with Body Mass Index in the studies group. Methods: Beck’s depression inventory questionnaire was used in 11 high schools for girls that were selected randomly from the schools in Baghdad/ AlKarkh from 1st of January 2023 till end of May 2023. A sample of 350 adolescent girls was included in the study. The height and weight of each participant was measured and BMI was calculated. Tables and graphs were constructed to describe the data. The Chi-square test was used to test the association between categorical data. A P value of less than 0.05 was considered statistically significant. Results: Of the studied group, 14% were underweight, 59% were normal weight, 21% overweight and 6% obese. As for mood status, 16% had mild mood disturbance, 24.3% had borderline clinical depression, 13.4% had moderate depression and 3.1% had severe depression. Severe depressive symptoms were found in 15% of obese girls, significantly higher than that among overweight (1.4%), normal weight (2.4%), and underweight (3.4%), P = 0.003. Conclusions: There was a significant association between obesity and severe depression and a positive significant correlation between BMI and depression.

Effects of Online Nutrition Training Program About Mediterranean Diet on Anthropometric Measurements and Diet Quality in Overweight and Obese Adolescent Girls

Objective: This study was conducted to evaluate the effect of an online nutrition training program about the Mediterranean diet for 8 weeks in overweight and obese female high school students on anthropometric measurements and diet quality.&#x0D; Methods: A total of 86 students between the ages of 14-18 years were included in the study, and they were divided into two groups as nutrition training (n=44) and control groups (n=42). The Mediterranean Diet Quality Index (KIDMED) scores were calculated and anthropometric measurements of groups were taken by the dietician at the beginning and at the end of the study.&#x0D; Results: The KIDMED score of the nutrition training group was 4.59±2.40 at the beginning, later on it increased to 7.43±2.57 after the program (p= .001). After the program, it was determined that the difference between the KIDMED scores of the nutrition training and control groups were statistically significant (p= .034), however the decrease in body weight (p= .09), BMI (p= .64), and waist circumference (p= .06) were similar between groups.&#x0D; Conclusion: As a result of the study, it can be said that online nutrition training program about the Mediterranean diet for 8 weeks may affect the diet quality positively of overweight and obese female adolescents, but long-term programs should be planned to determine the effects on anthropometric measurements.

Relationship between inflammatory biomarkers and insulin resistance in excess-weight Latin children.

Excess weight, inflammation, and insulin resistance (IR) are associated, but the prevalence of and biomarkers for IR in Latin children are unknown. This study aimed to determine the prevalence of IR in prepubertal and pubertal Latin children with excess weight and explore the usefulness of different biomarkers of low-grade inflammation for identifying IR status. Sixty-eight children (31 boys, 37 girls; approximately 11 years of age) with excess weight (overweight and obese) and 20 healthy normal-weight children (12 boys, 8 girls; approximately 12 years of age) were included. Anthropometric parameters, insulin, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, tumor necrosis factor- α (TNF-α), interleukin (IL)-6, monocyte chemoattractant protein-1 (MCP-1), soluble CD40 ligand (sCD40L), high-sensitivity C-reactive protein (hs-CRP), and myeloperoxidase were assessed and IR was determined by homeostasis model assessment index (cutoff points: 2.67 and 2.22 in prepubertal boys and girls and 5.55 and 3.82 in pubertal boys and girls, respectively). Intergroup differences were compared, correlations were investigated using Pearson correlation coefficient, and stepwise multiple linear regression analyses were performed to estimate the relationship between inflammatory biomarkers and IR. The prevalence of IR among overweight children was 62%. IL-6 levels differed between overweight and obese boys, while erythrocyte sedimentation rate, MCP-1, TNF-α, IL-6, hs-CRP, and sCD40L differed between obese and normal-weight boys. In contrast, sCD40L levels were increased in overweight versus normal-weight girls, while MCP-1, TNF-α, IL-6, and sCD40L differed between obese and normal-weight girls. Furthermore, MCP-1 and sCD40L levels and erythrocyte sedimentation rate were positively correlated with IR; however, a stepwise regression analysis that adjusted for the body mass index (BMI) z score, sex, and age showed that none were good predictors of IR status. The prevalence of IR is high among Latin children with excess weight. Although some inflammatory biomarkers differed among groups, none robustly predicted IR.
