RESUMO

The present study aimed to evaluate the association of sociodemographic factors and lifestyle with the consumption of in natura or minimally processed (INMP) foods, ultra-processed foods (UPFs), and fruits and vegetables. This was a cross-sectional study conducted with 403 children, aged 4 to 7 years, from a retrospective cohort. Sociodemographic and lifestyle variables were investigated using a sociodemographic questionnaire. Food consumption was assessed by three food records. Bivariate and multivariate linear regression analyses were used to analyze associations. Children with lower income had a higher consumption of INMP foods and a lower consumption of UPFs. A shorter time spent at school was associated with a lower consumption of INMP foods and a higher consumption of UPFs. Children with more screen time and less educated parents consumed less fruits and vegetables. Unfavorable sociodemographic factors were associated with a better profile of food consumption according to the level of processing, except for fruits and vegetables. The longer time spent at school and a shorter screen time contributed to a healthier diet.


Este estudo objetivou avaliar a associação de fatores sociodemográficos e estilo de vida com consumo de alimentos in natura ou minimamente processados (INMP), ultraprocessados (AUP) e frutas e hortaliças. Trata-se de estudo transversal com 403 crianças de 4 a 7 anos de uma coorte retrospectiva. Variáveis sociodemográficas e estilo de vida foram investigadas através do questionário sociodemográfico. O consumo alimentar foi avaliado por três registros alimentares. Empregaram-se análises de regressão linear bivariadas e multivariadas para analisar as associações. Crianças com menor renda apresentaram maior consumo de alimentos INMP e menor consumo de AUP. Menor tempo de permanência na escola associou-se ao menor consumo de alimentos INMP e maior consumo de AUP. Crianças com maior tempo de tela e com pais de menor escolaridade, consumiram menos frutas e hortaliças. Fatores sociodemográficos desfavoráveis se associaram ao melhor perfil de consumo de alimentos segundo o nível de processamento, exceto para frutas e hortaliças. O maior tempo de permanência na escola e menor tempo de tela contribuíram para uma alimentação mais saudável.

RESUMO

INTRODUCTION/OBJECTIVE: The lack of international consensus on the definition of Metabolic Syndrome (MS) in the pediatric population makes it difficult to estimate its prevalence. In this study, we intend to identify MS prevalence and a cutoff point based on a continuous score in children aged four to seven years. METHODS: A cross-sectional study of 402 children (4-7 years) monitored by the Lactation Support Program (PROLAC). A continuous MS risk score was assessed using Principal Component Analysis (PCA). In order to calculate the score, the following MS risk factors were considered: Waist circumference (WC), High Density Lipoprotein (HDL), Triglycerides (TG), Blood Pressure (BP) and Blood sugar. Using a Receiver Operating Characteristics (ROC) curve, the cutoff point for predicting MS risk based on continuous score was evaluated. RESULTS: A progressive increase in MS scores was observed according to increase in the number of risk factors. This increase was also observed when comparing boys and girls (p < 0.001). In the absence of MS, the median score among the children was -0.0486 (-0.2929-0.2151). For children with MS, the median score was 0.5237 (0.2286-0.7104) (p < 0.001). The best cutoff score for predicting MS in children aged four to five years was >0.09 (100% sensitivity and specificity 72.67%). For children aged six to seven years, this value was >0.14 (100% sensitivity and 64.65% specificity). CONCLUSION: The calculated continuous risk score can predict MS with good accuracy and high sensitivity and reasonable specificity.

RESUMO

The dietary exposure to low-calorie sweeteners (LCS) was estimated in a sample of pregnant Brazilian women. Consumption data were obtained with a 24-h Dietary Recall interview. Because of the uncertainty in assessing foods with LCS, they were classified into three scenarios to ensure inclusion of the 15 LCS allowed for use in Brazil: ranging from a less to a more conservative scenario. The concentration of LCS was estimated using the amount declared on the label or the maximum permitted levels and analytical determination data for table-top sweeteners. The frequency of consumption was higher for acesulfame-K, aspartame, and cyclamate. The food groups contributing the most to the consumption of LCS were non-alcoholic beverages, table-top sweeteners, confectionary and desserts. The level of dietary exposure to LCS was within the safety limit. However, continued efforts to monitor their dietary exposure are necessary given the limitations highlighted in this study.

RESUMO

The majority of studies on anemia are focused on children and women of reproductive age. Although the disease is a widespread public health problem, studies that include the rural population are scarce. This study determined the prevalence of anemia and associated factors in adults and the elderly living in the rural area of a municipality in Minas Gerais. Twelve rural communities were included. During home visits, hemoglobin levels were measured using a hemoglobinometer to check for the presence or absence of anemia. Additionally, anthropometric data and food insecurity data based on the Brazilian Food Insecurity Scale (EBIA) were collected. A questionnaire about socioeconomic, demographic, and housing conditions was applied. Analyses were performed using the Stata software version 13.0. Spearman correlation and regression analysis logistics were performed (p < 0.05) on 124 families (n = 297 farmers). The prevalence of anemia was 41.1%, being higher among women (55.7%). Additionally, 40.1% of the farmers were food insecure; 52.7% and 80.5% presented excess weight and cardiovascular risk, respectively. Poverty was a reality for 39.7% of individuals. A positive correlation between hemoglobin levels and per capita income was found as well as a negative correlation with EBIA scores and cardiovascular risk. Multivariate analysis showed that individuals experiencing food insecurity, the elderly, and those who do not own a property, were more likely to be anemic. Farmers with per capita income above 1/2 minimum wage were less likely to have anemia. The prevalence of anemia in the group studied was higher than previous studies. The disease is associated with factors that also predispose to food insecurity. The improvement of the determinants of insecurity can contribute to the fight against anemia.

RESUMO

Iodine is a micronutrient essential for maintaining normal body functioning, and the consumption depends on the distribution in the environment, and insufficient or excessive intake results in thyroid dysfunction. The purpose of this review was to evaluate the correlation between iodine concentration in drinking water and the iodine status of the population. The systematic review was conducted following the PRISMA guidelines and was registered at the International Prospective Register of Ongoing Systematic Reviews (CRD42019128308). A literature search was conducted using MEDLINE/PUBMED (National Library of Medicine), LILACS (Latin-American and Caribbean Literature on Health Sciences), and Cochrane Library, June 2021. The quality of the studies was assessed by a checklist for cross-sectional studies developed by Joanna Briggs Institute. The initial search identified 121 articles, out of which ten were included in this systematic review, and five were included in the meta-analysis. Among the articles listed, six adopted cutoff points to classify the iodine content in the drinking water. The study identified median iodine concentration in drinking water from 2.2 to 617.8 µg/L and the correlation between iodine concentration in drinking water and urinary iodine concentration was 0.92, according to meta-analysis. Furthermore, the iodine status was correlated to the iodine content in water. The determination of a cutoff point can contribute to the implementation of iodine consumption control measures.

RESUMO

Objective: The objective is to analyze the concentration of iodine in Brazilian drinking water and its possible contribution to iodine intake for different groups. Methods: Water samples collected from primary healthcare units in eight locations distributed across all five macroregions of Brazil were analyzed. The quantification of iodine in the water samples was done by spectrophotometry (leuco crystal violet method). To classify the degree of iodine concentration, the recommendation of the Ministry of Health (China) was followed since Brazil lacks a classification standard. To verify the possible contribution of drinking water to iodine intake for different groups, the recommended water intake for each group according to the United States Institute of Medicine (2004) was considered. The percentage of iodine in drinking water and its contribution to iodine intake for different physiological groups were calculated based on the estimated average requirement (EAR) of iodine. A descriptive statistical analysis was performed using SPSS version 21.0 and Statistical Analysis Systems (SAS) version 9.2. Results: Significant differences were found between the maximum and minimum concentrations of iodine in water samples from the same location. In Pinhais (south region), the difference was 44.32 µg· L-1; in Viçosa (southeast region), it was 27.86 µg·L-1; in Rondonópolis (midwest region), it was 12.66 µg·L-1; in São Luís (northeast region), it was 11.82 µg·L-1; in Brasilian Federal District (midwest region), it was 10.98 µg·L-1; in Macaé (southeast region), it was 10.14 µg· L-1; in Palmas (north region), it was 4.22 µg·L-1; and in Vitória (southeast region), it was 1.69 µg·L-1. The maximum concentrations of iodine found in the drinking water of Pinhais and Viçosa can contribute more than 70.0% and 50.0%, respectively, to daily iodine intake for all groups. Conclusion: Monitoring the concentration of iodine in drinking water from different locations in each city or Federal District is a preventive measure against inadequate iodine intake and possible adverse changes in population health.

RESUMO

Introduction: Iodine deficiency during pregnancy can cause hypothyroidism and goiter; in schoolchildren, it can cause reduced intelligence quotient. In excess, iodine can cause thyroiditis, goiter, and Hashimoto's hypothyroidism. Currently, schoolchildren and pregnant women are classified as risk groups for excessive iodine intake and iodine deficiency, respectively. Thus, determining iodine from all sources of consumption is important for intervention planning. Objective: To construct a theoretical model for the iodine intake of schoolchildren and pregnant women of a city in the Zona da Mata Mineira region, considering a healthy diet, salt consumption and water intake. Methodology: The dietary iodine intake of pregnant women was analyzed based on a dietary iodine table compiled from an international database. A dietary plan was prepared following the Brazilian Food Guide. Iodine concentration of different salt brands sold in local establishments was checked, and drinking water samples from healthcare facilities were analyzed. A descriptive and exploratory statistical analysis was performed and the results were presented in absolute and relative frequencies, and measures of central tendency and dispersion. Results: According to the proposed diet, pregnant women and schoolchildren would have a daily intake of 71.6 µg and 71 µg, respectively. Thirteen salt brands were evaluated, 69.2% complied with the legislation and the mean iodine content was 29.88 mg. The mean concentration of iodine in water was 25 µg iodine/liter and 14 µg iodine/liter, respectively, in summer and autumn. Considering the intake of food, salt, and drinking water according to the proposed dietary plan, the daily intake for pregnant women would be 279.5 and 253.5 µg for schoolchildren. Conclusion: The daily iodine intake of schoolchildren and pregnant women according to this theoretical model was excessive, considering a healthy dietary pattern. This theoretical model can guide actions and public policies aimed at targeting all forms of iodine intake.

RESUMO

The scope of this article is to evaluate the potentialities of indicators of the nutritional status of iodine in individuals or populations. The review was based on PRISMA. The search for articles occurred in January 2019, in the Pubmed, Scopus and LILACS databases, using the key words: indicators AND nutritional status AND iodine. The selection followed the stages of excluding the duplicates, reading the titles, abstracts and analyses in full. The methodological quality of the studies was evaluated by the Downs and Black instrument. A total of 178 studies were identified and 20 were included. Urinary Iodine Concentration (UIC) was analyzed in 65% of the studies and was considered the best indicator to evaluate the nutritional status of iodine in the population. Thyroglobulin was determined in 20% of the studies and reflected the pre-existing state of iodine. Thyroid stimulating hormone was verified in 45% of the articles and was important for the surveillance of iodine deficiency among newborns. Only one study evaluated capillary iodine, useful for analyzing long-term dietary intake. In the evaluation of methodological quality, the lowest score was 12 and the highest 16, in 17 possible points. The use of UIC is recommended for the diagnosis of deficiency and excess of iodine in the population.

RESUMO

OBJECTIVES: to analyze the factors associated with the use of alcohol, tobacco and illicit drugs among Brazilian undergraduate students. METHODS: observational, cross-sectional study, with convenience sampling, conducted in 2014/2015, involving institutional data and a self-completed online questionnaire, analyzed using measures of frequency, central tendency/dispersion and logistic regression. RESULTS: among 126,326 students, 62.8% reported alcohol use; 11%, tobacco; and 7.5%, illicit drugs. Several academic factors-such as not residing with family (sororities [alcohol: aOR:2.38;95%CI:2.28-2.48; tobacco: AOR:2.20;95%CI:2.09-2.33; illicit drugs: AOR:2.53;95%CI:2.38-2.70]), acting in university movements (student [alcohol: AOR:1.74;95%CI:1.65-1.83; tobacco: AOR:1.97;95%CI:1.86-2.08; illicit drugs: AOR:2.43;95%CI:2.28-2.59] and religious [alcohol: AOR:0.28;95%CI:0.26-0.29; tobacco: AOR:0.23;95%CI:0.21-0.26; illicit drugs: AOR:0.18;95%CI:0.16-0.21]) and lack of discipline/study habit (alcohol: AOR:1.41;95%CI:1.37-1.45; tobacco: AOR:1.53;95%CI:1.46-1.59; illicit drugs: AOR:1.85;95%CI:1.76-1.94) - were associated with the use of the three categories of substances. CONCLUSIONS: we identified that a number of academic factors are associated with licit and illicit drug use. These findings may help in designing preventive strategies among college students.

RESUMO

INTRODUCTION: Two main strategies are currently recommended for the prevention and control of iodine deficiency in the world: implementation of universal salt iodisation programmes and permanent monitoring of iodine consumption by the population. Although iodine intake and coverage iodised salt have increased in the world population, iodine deficiency disorders (IDDs) may still be a public health problem in a few countries or communities. OBJECTIVE: To assess the impact of salt iodisation programmes on urinary iodine concentrations and goitre rates in the world population. Methodology. A systematic review based on the PRISMA method. We obtained articles from Scopus, Science Direct, MEDLINE databases, and other sources between March and April 2020, without limitation of dates. "Iodisation" AND "urinary iodine concentrations" AND "goitre" in English, Portuguese, and Spanish without filters and clinical trial, case-control, and cross-sectional studies were included in this review. RESULTS: Of 479 abstracts, twenty-three were eligible. Coverage on iodised salt was in the range of 16 to 98%, and 11 studies had been sufficient, whilst eight studies had adequate iodine concentration in salt and three excess. 81.8% of studies that had an adequate median of UIC had a good impact in their respective salt iodisation programmes. CONCLUSION: After 18 years of salt iodisation programme implementation in the 13 countries, the majority achieved sustaining elimination of IDD whilst all had adequate median UIC; however, more detailed studies are still needed to confirm that all communities are equally protected of IDD.

RESUMO

This article sets out to identify the socio-demographic and nutritional factors associated with the nutritional status of iodine in the maternal-infant group. The review was based on the Prisma method and the Medline (PubMed), Scopus and Lilacs databases were consulted. The search was conducted in December 2018, using the key words nutritional status, iodine, infant, pregnant and lactating. The selection followed the stages of excluding duplicated articles, reading the titles, abstracts and texts in full. A total of 1,500 studies were identified and 26 met the inclusion criteria. The methodological quality of the studies was evaluated using the questionnaire proposed by Downs and Black. There was an association between the sociodemographic factors of income, education, maternal and gestational age, uniformity and place of residence in rural or urban areas with the nutritional state of iodine. In relation to dietary factors, the consumption of supplements, iodized salt and dietary sources of iodine, especially dairy products, play a protective role to avoid the deficiency. It is necessary to create more specific and effective strategies that address all the factors that affect the nutritional state of iodine to avoid the disorders resulting from the deficiency.

A qualidade metodológica dos estudos foi avaliada pelo questionário proposto por Downs e Black. Houve associação entre os fatores sociodemográficos renda, escolaridade, idade materna e gestacional, paridade e local de residência rural ou urbano com o estado nutricional de iodo. Já em relação aos fatores alimentares, o consumo de suplementos, sal iodado e alimentos fontes de iodo, em especial os produtos lácteos, exercem papel protetor contra a deficiência. É preciso criar estratégias mais específicas, efetivas e que contemplem todos esses fatores que afetam o estado nutricional de iodo para evitar as desordens provocadas pela deficiência.

RESUMO

The aim of this study is to identify maternal consumption of processed and ultra-processed foods and to verify the factors associated with the supply of these foods to Brazilian children. This is a cross-sectional study with 231 mothers and children aged from 6 to 24 months. The mother's and children's food consumption was measured using three 24-hour recalls. The foods consumed were categorised according to the NOVA classification. The data were analysed by multinomial logistic regression. The supply of processed and ultra-processed foods to children was associated with the child's age (T2: OR = 1.17, p<.001; T3: OR = 1.23, p<.001), the absence of breast milk consumption (T3: OR = 3.82, p=.006) and the greater consumption of these foods by mothers (T2: OR = 3.15, p=.018; T3: OR = 4.59, p=.004). We conclude that mothers who consume processed and ultra-processed foods also include them in complementary feeding, and the consumption of these foods by the child increases with age, absence of breastfeeding, and with increased maternal consumption.

RESUMO

Aimed at strengthening breastfeeding policies, human milk banks (HMBs) play an important role in promoting, protecting and supporting this practice. The objective of this study was to undertake a systematic review to identify activities developed by HMBs that demonstrate their role in promoting maternal and infant health. Searches for relevant articles were performed in the following databases: PubMed, Virtual Health Library (BVS), and BVS Breastfeeding linked to the portal of the Brazilian Human Milk Bank Network. Eleven articles were included in the final sample. The main topics covered by the articles were: the characteristics of breast milk donors; the importance of information provided by HMB professionals on maintaining breastfeeding for hospitalized premature infants; weight gain in premature babies fed on donated milk; HMB breastfeeding support actions; and factors influencing human milk donation. The actions developed by HMBs have a positive impact on the promotion of maternal and infant health, representing an important strategy for promoting breastfeeding and supporting the feeding of babies who are not able to feed directly at the breast.


Com o intuito de fortalecer as políticas públicas de saúde voltadas para a temática do aleitamento materno, os Bancos de Leite Humano (BLH) têm cumprido importante papel assistencial junto às puérperas e nutrizes, no sentido de promover, proteger e apoiar esta prática. O objetivo deste estudo foi realizar uma revisão sistemática para identificar as atividades dos BLH que demonstrem seu papel na promoção da saúde materno infantil. A pesquisa foi realizada nos portais de pesquisa PubMed e na Biblioteca Virtual de Saúde, sendo as buscas realizadas também pelo portal da Rede Brasileira de Bancos de Leite Humano. Após as buscas com os descritores foram incluídos 11 artigos. Os temas abordados foram sobre o perfil das doadoras de leite humano; a importância das informações recebidas dos profissionais do BLH para manutenção do aleitamento materno durante a internação de prematuros e; o ganho de peso em bebês prematuros que receberam leite humano; o apoio ao aleitamento materno por meio das ações do BLH e fatores que levaram à doação de leite humano. As ações desenvolvidas pelos BLH repercutem positivamente na promoção da saúde materno infantil, representando uma estratégia importante de promoção ao aleitamento e de apoio a amamentação dos bebês que não podem mamar diretamente no peito.

RESUMO

AIM: To propose an equation to estimate height and evaluate it's performance in the composition of adiposity indicators in community-dwelling older adults in Brazil. METHODS: It is a cross-sectional study with 675 community-dwelling older adults (≥60 anos). Interviews and anthropometric measurements were taken at subjects' homes. Body mass index (BMI), body adiposity index (BAI), waist height ratio (WHR), and conicity index (CI) were calculated. The height estimation equation was obtained by multiple linear regression. Concordance between height and the indicators measured and estimated was evaluated by the intraclass correlation coefficient (ICC) and Cohen's Kappa and Weighted Kappa indexes. Concordance was also evaluated by the Bland and Altman graphical approach. RESULTS: Equations of height estimation composed of knee height, sex, and schooling were proposed and stratified by age group (60-74 years and ≥75 years). In both age groups, almost perfect agreement (ICC ≥ 0.915 and Kappa ≥0.81) was found between height and adiposity indicators estimated and measured. CONCLUSION: The equation proposed is suitable to estimate height of the older adults, and can be a valuable tool for the evaluation of the nutritional status of Brazilian older adults in the community.

RESUMO

Overweight is increasing in the adolescent population and became a public health problem in the world. This study aimed to identify the body adiposity indices (BAI) with the best capacity to predict excess fat tissue and propose cut-off points for them, according to sex and adolescence period. This is a cross-sectional study. We calculated BMI, conicity index (CI), BAI, body roundness index (BRI), waist:height ratio (WtHR) and waist:hip ratio. Predictive capacity and cut-off points of adiposity indices were established by ROC (receiver operating characteristic) curves. We determined AUC-ROC and CI, stratified by sex and adolescence period. The best index to identify excess body fat in 10-13-year-old female adolescents was the WtHR (AUC = 0·92), like the BAI in girls aged from 14 to 16 years old (AUC = 0·87) and 17 to 19 years old (AUC = 0·80). In male adolescents aged from 10 to 13 years old and 14 to 16 years old, the best index was the WtHR (AUC = 0·93 and AUC = 0·8, respectively), like the BAI in boys aged from 17 to 19 years old (AUC = 0·95). The use of indices with specific cut-off points for each period of adolescence and according to sex is important for the reliable diagnosis of excess body fat. It is advisable to use indices together to obtain a more accurate assessment. Thus, the WtHR and BAI are reproducible and reliable, with high sensitivity and specificity values, and can be used together with the BMI.

RESUMO

Resumo Com o intuito de fortalecer as políticas públicas de saúde voltadas para a temática do aleitamento materno, os Bancos de Leite Humano (BLH) têm cumprido importante papel assistencial junto às puérperas e nutrizes, no sentido de promover, proteger e apoiar esta prática. O objetivo deste estudo foi realizar uma revisão sistemática para identificar as atividades dos BLH que demonstrem seu papel na promoção da saúde materno infantil. A pesquisa foi realizada nos portais de pesquisa PubMed e na Biblioteca Virtual de Saúde, sendo as buscas realizadas também pelo portal da Rede Brasileira de Bancos de Leite Humano. Após as buscas com os descritores foram incluídos 11 artigos. Os temas abordados foram sobre o perfil das doadoras de leite humano; a importância das informações recebidas dos profissionais do BLH para manutenção do aleitamento materno durante a internação de prematuros e; o ganho de peso em bebês prematuros que receberam leite humano; o apoio ao aleitamento materno por meio das ações do BLH e fatores que levaram à doação de leite humano. As ações desenvolvidas pelos BLH repercutem positivamente na promoção da saúde materno infantil, representando uma estratégia importante de promoção ao aleitamento e de apoio a amamentação dos bebês que não podem mamar diretamente no peito.


Abstract Aimed at strengthening breastfeeding policies, human milk banks (HMBs) play an important role in promoting, protecting and supporting this practice. The objective of this study was to undertake a systematic review to identify activities developed by HMBs that demonstrate their role in promoting maternal and infant health. Searches for relevant articles were performed in the following databases: PubMed, Virtual Health Library (BVS), and BVS Breastfeeding linked to the portal of the Brazilian Human Milk Bank Network. Eleven articles were included in the final sample. The main topics covered by the articles were: the characteristics of breast milk donors; the importance of information provided by HMB professionals on maintaining breastfeeding for hospitalized premature infants; weight gain in premature babies fed on donated milk; HMB breastfeeding support actions; and factors influencing human milk donation. The actions developed by HMBs have a positive impact on the promotion of maternal and infant health, representing an important strategy for promoting breastfeeding and supporting the feeding of babies who are not able to feed directly at the breast.

RESUMO

OBJECTIVE: To propose cut-off points for the TAG-glucose (TyG) index in Brazilian children and evaluate the link to cardiometabolic risk. DESIGN: A cross-sectional study with children from a municipality in Minas Gerais, Brazil. Anthropometric (weight, height, waist circumference and waist:height ratio), biochemical (lipid and glucose profile) and blood pressure (BP) tests were performed. Using the receiver operating characteristic curve, cut-off points for the TyG index were proposed according to sex using homoeostasis model of assessment - insulin resistance (IR) as the reference method. SETTING: Viçosa, MG, Brazil. PARTICIPANTS: Children aged 4-9 years (n 515). RESULTS: The TyG index cut-off points to identify the risk of IR were 7·9 and 8·1 for boys and girls, respectively. We observed that 48·7 % of the children had an increased TyG index. The increased TyG index was associated with overweight, total body and central fat, increased BP and altered lipid profile. Children with an increased TyG index had a higher accumulation of cardiometabolic risk factors. CONCLUSIONS: According to the cut-off points proposed by the current study, children at risk of IR estimated by the TyG index presented a higher cardiometabolic risk, including isolated risk factors, as to the higher accumulation of these.

RESUMO

Insulin resistance (IR) in childhood plays a key role in the development of metabolic changes in adulthood, therefore, it is important to diagnose it early. We aimed to investigate studies that evaluated the TyG index for prediction of IR risk and other cardiometabolic risk factors, as well as, the proposed cutoff points in childhood and adolescence. This is a systematic review elaborated according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA). The search was performed in Lilacs, PubMed and CAPES Journal Portal, using the terms "TyG index OR triglyceride-glucose index OR triglyceride and glucose index AND children OR adolescent*". Eight articles were included in this review. All were cross-sectional studies with individuals aged ≥2 and ≤20 years old, from the United States, Korea, Mexico, Brazil, and Iran. We concluded that the TyG index was positively associated with other IR prediction methods and appears to be advantageous for predicting IR risk and other cardiometabolic risk factors in children and adolescents (review registration: PROSPERO CRD42018100726).
