Prevalence Of Obesity In Adolescents Research Articles

Relationship Between Central Obesity and The Risk of Hypertension in Obesity Adolescents

The increasing prevalence of central obesity in adolescents is accompanied by an increase in risk factors for cardiovascular disease. The study aims to analyze the relationship between central obesity and the risk of hypertension in obese adolescents, including both male and female subjects. This study was undertaken to provide opportunities for further exploration of the relationship between central obesity and hypertension in adolescents. The study was a retrospective observational study that utilized medical record data from a previous research project entitled "Polimorfisme Gen Adiponectin ADIPOQ +45 T>G, ADIPOQ – 11377 C>G dengan Kadar Adiponektin Pada Remaja Obesitas dan Resiko Sindrom Metabolik." This data was obtained from research conducted on obese adolescents aged 13-18 years in junior and senior high schools in Surabaya and Sidoarjo who met the criteria. The sample comprised 140 obese adolescents, who were then categorized into two groups: those without central obesity and those with central obesity. Statistical data were analyzed using SPSS with the Chi Square test. There is a very strong and significant relationship between central obesity and the risk of hypertension in obese adolescents (p = 0.000; r = 0.373); central obesity and the risk of hypertension in obese male adolescents (p = 0.001; r = 0.587); and central obesity and the risk of hypertension in obese female adolescents (p = 0.003; r = 0.300). The study found a significant relationship between central obesity and hypertension risk in obese adolescents. Adolescents with central obesity were 3.6 times more likely to develop hypertension than those without. Male adolescents with central obesity were 6.5 times more likely to develop hypertension than those without. Female adolescents with central obesity were 2.9 times more likely to develop hypertension

Effects of accelerometer-based sedentary time and physical activity on DEXA-measured fat mass in 6059 children

Globally, childhood obesity is on the rise and the effect of objectively measured movement behaviour on body composition remains unclear. Longitudinal and causal mediation relationships of accelerometer-based sedentary time (ST), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) with dual-energy X-ray absorptiometry-measured fat mass were examined in 6059 children aged 11 years followed-up until age 24 years from the Avon Longitudinal Study of Parents and Children (ALSPAC), UK birth cohort. Over 13-year follow-up, each minute/day of ST was associated with 1.3 g increase in fat mass. However, each minute/day of LPA was associated with 3.6 g decrease in fat mass and each minute/day of MVPA was associated with 1.3 g decrease in fat mass. Persistently accruing ≥60 min/day of MVPA was associated with 2.8 g decrease in fat mass per each minute/day of MVPA, partly mediated by decrease insulin and low-density lipoprotein cholesterol. LPA elicited similar and potentially stronger fat mass-lowering effect than MVPA and thus may be targeted in obesity and ST prevention in children and adolescents, who are unable or unwilling to exercise.

Status and challenges of obesity prevention and management in Chinese children and adolescents

Status and challenges of obesity prevention and management in Chinese children and adolescents

The return on investment for the prevention and treatment of childhood and adolescent overweight and obesity in China: a modelling study

The rapid increase in child and adolescent overweight and obesity (OAO) in China has a significant health and economic impact. This study undertook an investment case analysis to evaluate the health and economic impacts of child and adolescent OAO in China and the potential health and economic returns from implementing specific policies and interventions. The analysis estimates the reduction in mortality and morbidity from implementing a set of evidence-based interventions across China between 2025 and 2092 using a deterministic Markov cohort model. Modelled interventions were identified by literature review and expert recommendation and include fiscal and regulatory policies, eHealth breastfeeding promotion, school-based interventions, and nutritional counselling by physicians. The study applies a societal costing perspective to model the economic impact on healthcare cost savings, wages, and productivity during adulthood. By projecting and comparing the costs between a status quo scenario and an intervention scenario, the study estimates the return on investment (ROI) for interventions separately and in combination. Without intervention China will experience 3.3 billion disability-adjusted life years (DALYs) due its current levels of child and adolescent OAO and a lifetime economic impact of CNY 218 trillion (USD 31.6 trillion), or a lifetime CNY 2.5 million loss per affected child or adolescent (USD 350 thousand). National implementation of all five interventions would avert 179.4 million DALYs and result in CNY 13.1 trillion of benefits over the model cohort's lifetime. Implementing fiscal and regulatory policies had the strongest ROI, with benefits accruing at least 10 years after implementation. Scaling up China's current school-based interventions offers China significant health and economic gains, however, the ROI is lower than other modelled interventions. Effective prevention and treatment of child and adolescent OAO is critical to China's health and economic development. Multiple interventions offer a comprehensive approach to address the various factors that increase risk of child and adolescent OAO. Nonetheless, fiscal and regulatory policies offer the strongest health and economic gains. Funding was provided by UNICEF China.

A literature review of evidence for primary prevention of overweight and obesity in healthy weight children and adolescents: A report produced by a working group of the Danish Council on Health and Disease Prevention.

Primary prevention targets development of overweight in individuals with healthy weight and is a great challenge. This paper summarizes the main findings of a working group of the Danish Council on Health and Disease Prevention that reviewed the literature on primary prevention of overweight and obesity among children and adolescents. The results were presented in a Danish report, in which a 2019 Cochrane review on childhood obesity prevention was complemented by searches in PubMed to include all relevant subsequent studies published from January 2018 until March 2020. In this paper, the review was updated until June 2023. Numerous childhood overweight prevention interventions have been developed during the past decades, primarily targeting diet and/or physical activity. Several of these interventions showed positive effects on diet and physical activity level but did not show effects on risk of developing overweight. The evidence foundation is inconsistent as four out of five interventions did not show positive effects. Previously observed intervention effects may not reflect excessive weight gain prevention among children with healthy weight but rather bodyweight reduction among those with overweight or obesity. We do not have sufficient knowledge about how to prevent children with healthy weight from developing overweight, and creative solutions are urgently needed.

Nutrition Education “SAGARI” (Check Your Waist Circumference) as an Attempt to Prevent Adolescents’ Obesity

The incidence of obesity at all ages in Indonesia, including adolescents, has increased. Obesity has a negative impact on physical and social health in adolescents. Excessive food consumption and lack of physical activity are risk factors for obesity in adolescents. Based on this urgency, it is necessary to prevent obesity in adolescents. The purpose of this Community Service activity was to increase adolescents’ understanding of the importance of the 4 pillars of balanced nutrition in efforts and to change attitudes by measuring waist circumference regularly to prevent obesity. Increasing knowledge and attitudes to prevent obesity was obtained by providing a Nutrition Education Program named "SAGARI" (Check Your Own Waist Circumference). The program activities included counseling on the 4 pillars of balanced nutrition with lecture method, demonstration for measuring waist and hip circumferences, measuring nutritional status for SMK students consisting of measuring waist circumference (WC) and body mass index (BMI), and providing measuring tape "SAGARI". The results of this activity were an increase in the median knowledge score from 70.00 to 80.00 and an average attitude score from 3.00 to 3.91 related to obesity prevention in adolescents. These results showed that the "SAGARI" nutrition education program can increase students' knowledge and attitudes regarding obesity prevention which is expected to be implemented through daily behavior. Keywords: Balance nutritional, waist circumference, obesity, adolescent, nutritional status.

The Effectiveness of a Telenutrition Intervention to Improve Dietary Behavior and Physical Activity Among Adolescents With Obesity: Protocol for a Systematic Review.

The global obesity pandemic among adolescents is becoming a public health issue throughout the world. Telehealth use has significantly increased during and after the COVID-19 pandemic, including its application in adolescent obesity prevention and treatment. This review aims to synthesize the evidence on the effectiveness of telenutrition in improving dietary behavior and physical activity in adolescents with obesity. The PRISMA-P (Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols) guideline will be used to structure this protocol. The focus of the systematic review is guided by the population, intervention, comparator, and outcome (PICO) framework. A systematic search of Science Direct, PubMed, Cochrane, Embase, JMIR, ProQuest, and Google scholar databases will be conducted. Two authors will screen the titles and abstracts of identified studies independently and select studies according to the eligibility criteria. The full-text reading will be done independently by 2 reviewers to assess final eligibility. Any discrepancies will then be discussed and resolved. The Cochrane Collaboration Risk of Bias tool was used to assess the risk of bias; a descriptive analysis will summarize the effectiveness of the telenutrition or any type of telehealth intervention used. The systematic review is expected to be completed by the end of March 2024. The ongoing screening and review of the articles are currently being conducted. This systematic review aims to summarize the effectiveness, features, design process, usability, and coherence of a telenutrition intervention using behavior change theory to improve dietary patterns and physical activity among adolescents with obesity. It will identify areas for improvement and best practices, informing the development of more useful and engaging telenutrition interventions for adolescents.

Socioecologic Factors Associated With Obesity in Adolescents With Epilepsy in the United States.

Obesity among youth with epilepsy has multifactorial etiology, yet socioecologic obesity risk factors (eg, neighborhood factors) have not been examined in this population. This study examined (1) the prevalence of obesity adjusting for relevant covariates and (2) socioecologic correlates of obesity in adolescents with epilepsy aged 10-17 years. This cross-sectional study used 2017-2018 National Survey of Children's Health data (total n = 27,094; epilepsy n = 184). Chi-square tests compared weighted prevalence of obesity with relevant covariates among all adolescents and adolescents with epilepsy. Weighted multiple logistic regression models were conducted to adjust for covariates. The prevalence of obesity in adolescents with epilepsy was 27.8% (95% confidence interval [CI] 15.4%-40.3%) vs 15.1% (95% CI 14.1%-16.2%) for the non-epilepsy group. Adolescents with epilepsy also had higher odds of obesity after adjusting for age, gender, race/ethnicity, household income, physical activity, and medical home (odds ratio [OR] 2.1, 95% CI 1.2-3.8). Adjusting for sociodemographics, anxiety (OR 4.5, 95% CI 1.3-15.6), 2 or more adverse childhood experiences (OR 7.3, 95% CI 1.6-33.4), neighborhood detracting elements (eg, OR 5.2, 95% CI 1.5-18.5 for 1 detracting element), and forgone care (ie, unmet health care needs) (OR 22.4, 95% CI 3.8-132.8) were associated with obesity in adolescents with epilepsy. Adjusting for multiple comparisons, neighborhood detracting elements (P < .0001) and forgone care (P < .0007) remained significant. Variables related to mental health, family functioning, built environment, and forgone care were associated with obesity in adolescents with epilepsy, but the association was not fully explained by these factors. Obesity interventions for this population should consider multiple levels of influence including the community and special health care needs of this population.

Analysis of public perception of national obesity management policy.

This study aimed to provide essential data necessary for shaping future obesity policy directions and strengthening the effectiveness of such measures. A literature review and expert meetings were conducted to identify policy objectives that should be included in the comprehensive national obesity management plan. Based on these objectives, a questionnaire was developed, and a survey was conducted nationwide through an online panel targeting citizens aged 15-69. When analyzing the appropriateness of promoting national obesity policies, 38.6% of respondents answered "not appropriate," while only 8.4% answered "appropriate." We also assessed the importance of the four key areas of the national obesity management policy, with 36.9% considering "improvement of lifestyle to prevent obesity" as the most important. Additionally, we analyzed the significance of specific tasks. "Strengthening child and adolescent obesity prevention and management," "enhancing group meal nutrition and hygiene," "strengthening the operation of community-based obesity and exercise clinics," and "advancing an integrated information platform for nutrition, dietary patterns, and physical activity" emerged as pivotal tasks within their respective areas. The primary tasks identified as top priorities by the public in this study regarding national obesity policy initiatives can be incorporated into future obesity management strategies. Our approach has the potential to enhance the efficacy of these policies by aligning future obesity policy trajectories with public demands and expectations.

Prevalence and Associated Factors of Adolescent Obesity among Rural School Adolescents in Nepal: A Cross-Sectional Study.

Overweight and obesity are major risk factors for chronic diseases and are the leading cause of mortality worldwide. Obesity during adolescence is strongly associated with adulthood obesity leading to increased morbidities and mortality. As a developing country undergoing rapid urbanization, Nepal is in a transitional phase where undernutrition coexists with obesity; however, there is a dearth of literature on the status of adolescent obesity in the rural section of Nepal. The aim of this study was to determine the prevalence of adolescent obesity in a rural district of Nepal and find out its associated factors. An institution-based cross-sectional study was conducted among the adolescent students studying in classes 8, 9, and 10 in four secondary schools of Gosaikunda rural municipality of Rasuwa district, Nepal. Total enumerative sampling was used, and Global School-based Health Survey (GSHS) standard questionnaires were used in collecting the information. Height and weight measurements were taken, and the body mass index was classified according to Asia-Pacific criteria. The collected data were analyzed using "SPSS" version 22. Logistic regression analysis was used to evaluate the associated factors, and a p value of ≤0.05 was considered statistically significant. Out of 267 adolescents, 14.6% were obese and 14.6% were overweight. Of the female participants, 39.6% were either obese or overweight, while 12.6% of the male adolescents were overweight/obese. Among the total participants, 16.5% were underweight, including 14.0% females and 20.4% males. Female adolescents were about five times (AOR: 5.2, 95% CI (2.5-10.9), p < 0.01) more likely of being overweight/obese than male adolescents. More than one-quarter of the adolescents were found to be obese/overweight, and the prevalence was significantly more among female adolescents. It emphasizes the necessity of school-based programs promoting a healthy lifestyle among students to maintain healthy weight status.

Understanding the dynamics emerging from the interplay among poor mental wellbeing, energy balance-related behaviors, and obesity prevalence in adolescents: A simulation-based study.

Both obesity and poor mental wellbeing have a high prevalence in European youth. Adolescents in six countries identified mental wellbeing factors as main drivers of youth obesity through systems mapping. This study sought to (1) explore the dynamics of the interplay between poor mental wellbeing, energy balance-related behaviors, and adolescent overweight and obesity prevalence and (2) test the effect of intervention point scenarios to reduce adolescent obesity. Drawing on the youth-generated systems maps and a literature synthesis, we built a simulation model that represents the links from major feedback pathways for poor mental wellbeing to changes in dietary, physical activity, and sleep behaviors. The model was calibrated using survey data from Norway, expert input, and literature and shows a good fit between simulated behavior and available statistical data. The simulations indicate that adolescent mental wellbeing is harmed by socio-cultural pressures and stressors, which trigger reinforcing feedback mechanisms related to emotional/binge eating, lack of motivation to engage in physical activity, and sleep difficulty. Targeting a combination of intervention points that support a 25% reduction of pressure on body image and psychosocial stress showed potentially favorable effects on mental wellbeing-doubling on average for boys and girls and decreasing obesity prevalence by over 4%.

Assessing the Impact of COVID-19 Prevention Measures on Adolescent Growth in Italy.

COVID-19 infection has caused increased morbidity and mortality worldwide. Several strategies have been adopted around the world to prevent its spread. Italy underwent a long lockdown for face-to-face educational activities, which were replaced with online classes. This longitudinal study aimed to analyze the effects of COVID-19 prevention measures on physical growth and body image perception in a sample of Italian adolescents who experienced the pandemic-induced lockdown in 2020. In particular, we wished to ascertain how lifestyle changes had affected their growth rates and health. Special attention was paid to increases in adiposity indicators (BMI, waist circumference, waist-to-height ratio) and weight caused by reduced physical activity, and consequent possible dissatisfaction with body image. We assessed the impact of school closures by comparing the annual growth rate and body image perception changes of adolescents (n = 60; age = 11.3 ± 0.4 years) who experienced this isolation with those in the following years who did not experience these restrictions (n = 68; age = 11.4 ± 0.3 years). As a consequence of the lockdown, our results indicate a greater annual growth rate in weight and other indices of adiposity (p < 0.05). As the virus is continuing to evolve and propagate, larger population studies can verify and confirm our findings. In promoting health policy to prevent the ongoing prevalence of obesity in adolescents, an accurate assessment of whether the increase in obesity rates during the pandemic is to be considered a temporary trend is highly recommended.

Assessment of Diet Quality in Children and Adolescents with Overweight or Obesity in Greece.

The adoption of healthy nutritional habits constitutes one of the most important determinants of healthy growth and development in childhood. Few studies in Greece have examined children's diet quality using diet indices. The present study aimed to assess the diet quality of a large cohort of children and adolescents with overweight or obesity. Study participants (n = 1335), aged 2-18, were recruited through the Out-patient Clinic for the Prevention and Management of Overweight and Obesity in Childhood and Adolescence, Aghia Sophia Children's Hospital, Athens, Greece. Anthropometric, socio-demographic, and behavioral data were collected using standard methods and equipment. The Diet Quality Index (DQI), which includes four subcomponents (i.e., dietary diversity, dietary quality, dietary equilibrium, and meal index), was calculated to assess each subject's diet quality. According to the results of this study, children's total DQI score was 63.1%. It was observed that 66.7% of the children had at least moderate diet quality (total DQI ≥ 59.34%). Boys had higher values of the total DQI and certain components of the DQI (i.e., dietary equilibrium score and meal index) compared to girls. Three out of ten children with overweight/obesity had poor diet quality (i.e., DQI ≤ 59.33). Younger children (2-5 years old) were found to have the lowest values of dietary equilibrium compared to older children (6-9 and 12-18 years old). Moreover, boys had higher values of the total DQI score and of specific components of this index (i.e., dietary equilibrium and meal index) compared to girls. Children living in urban areas had higher values in the dietary quality score compared to those living in rural areas. Children with overweight had higher values of the dietary quality score and the total DQI score compared to children with obesity. The present study highlighted that children and adolescents with overweight or obesity have poor diet quality. Multilevel and higher intensity interventions should be designed specifically for this group to achieve tangible outcomes.

Investment case for the prevention and reduction of childhood and adolescent overweight and obesity in Mexico.

Despite efforts to curb the rise in Mexico's child and adolescent overweight and obesity rates, prevalence in Mexico has grown by 120% since 1990 to 43.3% in 2022. This investment case identifies policies that will produce the largest returns for Mexico. The investment case model builds beyond a cost-of-illness analysis by predicting the health and societal economic impact of implementing child and adolescent overweight and obesity interventions in a cohort aged 0-19 from 2025 to 2090. The Markov model's impacts include healthcare expenditures, years of life lost, and reduced wages and productivity. We projected and compared costs in a status quo scenario to an intervention scenario to estimate cost savings and calculate return-on-investment (ROI). Total lifetime health and economic costs amount to USD 1.8 trillion-USD 30 billion on average per year. Implementing five interventions can reduce lifetime costs by approximately 7%. Each intervention has a low cost per disability-adjusted life year averted over 30-year, 50-year, and lifetime horizons. The findings demonstrate that a package of interventions mitigating child and adolescent overweight and obesity offers a strong ROI. The novel investment case methods should be applied to other countries, particularly low- and middle-income countries.

Overweight children in rural Norway - public health nurses' possibilities and limitations within national guidelines.

Globally, overweight and obesity are more prevalent in rural areas than in urban areas. The purpose of this study was to determine to what extent public health nurses in rural areas in Norway feel equipped to tackle the overweight and obesity epidemic within two sets of national guidelines: The National Guidelines for the Standardized Measurement of Height and Weight and The National Guidelines for the Prevention, Identification, and Treatment of Overweight and Obesity in Children and Adolescents. These guidelines are inspired by New Public Management (NPM) logic, which emphasises more market orientation within the public sector to obtain a more cost-effective supply of public goods. The focus is on the weighing of schoolchildren, available resources, inter-agency cooperation and the rural context. The data were collected using a structured questionnaire among 40 public health nurses working with children in rural areas, as well as qualitative interviews with 25 informants involved in the prevention and treatment of overweight and obesity among rural children. The study shows that rural public health nurses worry about the lack of resources for follow-up with children with a body mass index greater than what is characterised as 'normal'. The public health nurses suggested better cooperation between different stakeholders to work around the lack of resources and at the same time be able to see the whole picture, considering that overweight and obesity are complex problems connected to different challenges. They believed that it is an advantage to see the individuals in their local surroundings, to know their family history, their leisure activities and so on. This might be easier in rural areas than in urban areas, as these areas are often more transparent. There was consensus among the public health nurses involved in this study that national guidelines for treating overweight and obesity in children with the principles of NPM, and simplifying and standardising services, adds challenges instead of solutions. Such practices also hinder the use of experience-based knowledge about both the individual and the local context. There is a need for more flexible guidelines that can easily be adapted to the local (rural) context.

1832-PUB: SECRET—Screening and Educating Adolescents for Obesity

Background: India is predicted to have over 27 million children with obesity, representing over half of the children with obesity in the region and 1 in 10 of all children globally. Aim: To study Obesity prevalence in Adolescents and making timely interventions for healthier lifestyle adoption in urban and rural Ahmedabad. Methodology: A team of physician, nurse, pediatrician, educator took up the task of collecting data from schools in the rural and urban areas of Ahmedabad and periphery of 50kms during months of March-May 2022 with prior consent from guardians at 4 schools. Data including height, weight, abdominal girth, neck circumference was collected along with survey on food intake, type, exercise and habits. Adolescents of age category 14-18 yrs were included. Menstrual history was taken. Obesity was defined using the National Center for Disease Control definitions. We used the NHANES proposed cutoff of ≥90th percentile of Waist Circumference for identifying central obesity and Neck Circumference ≥ 50th percentile for identifying obesity. BP measurement and acanthosis assessment was also done. We conducted seminars on healthy eating and physical activity for all kids irrespective of their health status. Results: Total Cohort: 800, 14-18 years with a 1:1 ratio of girls:boys and same in rural and urban areas. There was higher prevalence of overweight in girls compared with boys (16%vs 12%), but the prevalence of obesity is higher in boys than girls (8%vs6%), the prevalence of underweight is slightly higher in boys than girls (21%vs9.5%). Underweight is more prevalent in rural areas vs obesity in urban areas. Conclusion: Screening adolescents for obesity, and making timely interventions for the prevention of disorders through education and appropriate lifestyle interventions can be one step towards a healthy future of the country. There lies necessity for expanding these screening and education programs through ROOTS ie Recognition, Obesity monitoring, Obesity prevention, Treatment and System based approach.

Mixed-Methods Evaluation of Father Participation in an Adolescent Obesity Prevention Program With Multiple Delivery Methods.

Padres Preparados, Jóvenes Saludables was a Latino family-based obesity prevention intervention implemented from 2017 to 2020 across eight programs in-person only, in a blended format (online/in-person), and online only. The intervention aimed to enhance father parenting skills to improve adolescent diet and activity behaviors. Mothers were encouraged to attend. Factors associated with participation were explored using a mixed-methods, qualitative (focus group/individual interviews by Zoom) and quantitative (process evaluation) design. Eleven focus group and 24 individual interviews were completed after participation with 24 fathers, 27 mothers, and 40 adolescents with responses not sorted by delivery method before analysis. Binomial logistic regression models examined associations between fathers' program completion and predictor variables of delivery characteristics, father demographic characteristics, and family attendance patterns. Parents were married (96% fathers, 76% mothers), had low income, a high school education or less (68% fathers, 81% mothers), and had lived in the United States a mean of 19 years. Parents were motivated to participate to improve health, and to be involved with and improve communication with their child. Common barriers to participation were work and life priorities and programmatic factors including scheduling conflicts and technological issues. Participation was greater for fathers attending sessions in-person compared with online only (OR = 11.6). Fathers were more likely to participate if they attended sessions with family members vs. not attending with family members (OR = 7.2). To maximize participation, findings suggest involving multiple parents/caregivers and adolescents, addressing contextual and programmatic barriers, and promoting benefits of better health and relations with family members.

Hubungan Konsumsi Sayur dan Buah dengan Kegemukan Remaja di Kota Padang

Less consumption of vegetables and fruit in adolescents causes obesity. Vegetables and fruit are sources of fiber, vitamins and minerals. The aim of the study was to determine the relationship between vegetable and fruit consumption and obesity in adolescents in Padang City. This research is a quantitative research with an analytic type using an observational cross sectional study design. Data collection in June-August 2022 at four high schools in the city of Padang with a total sample of 240 respondents. The sampling technique is multi-stage random sampling. Analysis using the chi square test. The results showed that there was no significant relationship between vegetable consumption habits and obesity in adolescents with a value of p=0.273, there was a relationship between the portion of vegetable consumption and obesity in adolescents with a value of p=0.000, there was no relationship between fruit consumption habits and obesity in adolescents with p = 0.121, there is a relationship between fruit consumption and obesity in adolescents with p = 0.049. Conclusion: The prevalence of obesity in adolescents in Padang City is 19.6%, more than 50% of adolescents have a habit and portion of consuming vegetables and fruit that is still lacking. It is recommended that adolescents have the habit of consuming vegetables and fruit as recommended, namely ≥3 servings/day (≥250 gr/day) of vegetables and ≥3 servings/day (≥150 gr/day) of fruit.

RELATIONSHIP BETWEEN SKELETAL MASS INDEX AND DIFFERENT OBESITY METABOLIC PHENOTYPES AMONG ADOLESCENTS IN CHINA

Objective: To explore the relationship between skeletal mass index (SMI) and different obesity metabolic phenotypes among adolescents,and to provide a theoretical basis for the prevention and control of obesity and related metabolic diseases in adolescents. Design and method: A total of 1352 adolescents aged 12-18 were randomly selected for questionnaire survey,physical measurements,body composition determination and laboratory testing. Multiple logistic regression analysis was used to analyze the correlation intensity between SMI and different metabolic phenotypes of obesity. Results: The metabolically unhealthy normal weight (MUNW) phenotype, metabolically healthy obesity(MHO) phenotype and metabolically unhealthy obesity(MUO) phenotype had lower levels of SMI compared to the metabolically healthy normal weight(MHNW) phenotype among adolescents,with all differences being statistically significant(P-values were all less than 0.001). Similar results were found after stratification by sex. Multiple logistic regression analysis showed that after adjusting for sex, SMI were protective factors for MUNW phenotype, MHO phenotype and MUO phenotype in adolescents(P-values were all less than 0.001),with the 0.86(95%CI:0.85,0.92),0.78(0.75,0.82) and 0.73(0.70,0.76) increased risks of MUNW phenotype, MHO phenotype and MUO phenotype associated with each unit rise in SMI, similar results were found after stratification by sex. Conclusions: SMI were protective factors for MUNW phenotype, MHO phenotype and MUO phenotype among adolescents. Attention should be paid to the assessment and supervision of adolescent skeletal muscle quality when prevented obesity and related metabolic risks,reducing the risk of abnormal cardiovascular metabolism in adolescents.

Relationship between skeletal muscle mass index and metabolic phenotypes of obesity in adolescents

To study the relationship between skeletal muscle mass index (SMI) and metabolic phenotypes of obesity in adolescents, and to provide a basis for the prevention and control of adolescent obesity and related metabolic diseases. A total of 1 352 adolescents aged 12 to 18 years were randomly selected by stratified cluster sampling in Yinchuan City from October 2017 to September 2020, and they were surveyed using questionnaires, physical measurements, body composition measurements, and laboratory tests. According to the diagnostic criteria for metabolic abnormalities and the definition of obesity based on the body mass index, the subjects were divided into four metabolic phenotypes: metabolically healthy normal weight, metabolically healthy obesity, metabolically unhealthy normal weight, and metabolically unhealthy obesity. The association between SMI and the metabolic phenotypes was analyzed using multivariate logistic regression. The SMI level in the metabolically unhealthy normal weight, metabolically healthy obesity, and metabolically unhealthy obesity groups was lower than that in the metabolically healthy normal weight group (P<0.001). Multivariate logistic regression analysis showed that after adjusting for gender and age, a higher SMI level was a protective factors for adolescents to develop metabolic unhealthy normal weight, metabolically healthy obesity, and metabolically unhealthy obesity phenotypes (OR=0.74, 0.60, and 0.54, respectively; P<0.001). Increasing SMI can reduce the risk of the development of metabolic unhealthy/obesity.
