Effects of infant feeding with goat milk formula or cow milk formula on atopic dermatitis: protocol of the randomised controlled Goat Infant Formula Feeding and Eczema (GIraFFE) trial.

INTRODUCTION: Atopic dermatitis (AD) is a chronic, inflammatory skin condition significantly affecting quality of life. A small randomised trial showed an approximately one-third lower incidence of AD in goat milk formula-fed compared with cow milk formula-fed infants. However, due to limited statistical power, AD incidence difference was not found to be significant. This study aims to explore a potential risk reduction of AD by feeding a formula based on whole goat milk (as a source of protein and fat) compared with a formula based on cow milk proteins and vegetable oils. METHODS AND ANALYSIS: This two-arm (1:1 allocation), parallel, randomised, double-blind, controlled nutritional trial shall enrol up to 2296 healthy term-born infants until 3 months of age, if parents choose to start formula feeding. Ten study centres in Spain and Poland are participating. Randomised infants receive investigational infant and follow-on formulas either based on whole goat milk or on cow milk until the age of 12 months. The goat milk formula has a whey:casein ratio of 20:80 and about 50% of the lipids are milk fat from whole goat milk, whereas the cow milk formula, used as control, has a whey:casein ratio of 60:40 and 100% of the lipids are from vegetable oils. The energy and nutrient levels in both goat and cow milk formulas are the same. The primary endpoint is the cumulative incidence of AD until the age of 12 months diagnosed by study personnel based on the UK Working Party Diagnostic Criteria. The secondary endpoints include reported AD diagnosis, measures of AD, blood and stool markers, child growth, sleep, nutrition and quality of life. Participating children are followed until the age of 5 years. ETHICS AND DISSEMINATION: Ethical approval was obtained from the ethical committees of all participating institutions. TRIAL REGISTRATION NUMBER: NCT04599946.

Publicidad de alimentos no saludables. Posicionamiento del Comité de Nutrición y Lactancia Materna de la Asociación Española de Pediatría / Unhealthy food advertising. A position paper by the AEP Committee on nutrition and breastfeeding

Introducción: Entre los factores más importantes que influyen en la aparición y el mantenimiento de malos hábitos de alimentación están la accesibilidad y publicidad de los productos alimentarios menos saludables. Con el objetivo de elaborar y fundamentar recomendaciones, se ha realizado un análisis de la evidencia disponible sobre el impacto de la publicidad de alimentos en la salud de niños y adolescentes. Métodos: Se ha realizado una revisión bibliográfica de revisiones sistemáticas y metaanálisis publicados hasta enero del 2022 con el término «food advertising», incluyendo aquellas que analizaban el impacto de la publicidad de alimentos sobre el peso, el índice de masa corporal, la adiposidad, la ingesta dietética, la conducta ante el producto anunciado, su compra o su consumo en niños y adolescentes. Resultados: Fueron incluidas 21 revisiones sistemáticas que incluyen un total de 490 artículos, 5 de las cuales contienen además un metaanálisis. La gran mayoría de los estudios primarios evalúan efectos intermedios, relacionados con el comportamiento de niños y adolescentes ante los productos anunciados y su consumo. Existe gran variedad en cuanto al tipo de publicidad y efectos estudiados. La mayoría de los trabajos muestra una asociación entre el tipo de publicidad y el efecto concreto analizado, siendo más evidente en menores de 12 años y en niños obesos. Las revisiones más recientes se centran en la publicidad on-line indicando sus efectos nocivos especialmente en adolescentes. (AU)

Introduction: Some important factors influencing and maintaining unhealthy habits are food advertising and products accessibility. In order to develop and support recommendations, an analysis of the available evidence on the impact of food advertising on the health of children and adolescents has been carried out. Methods: Literature review of systematic reviews and meta-analyses published up to January 2022 for the term «food advertising» that analyzed the impact of food advertising on weight, body mass index, adiposity, dietary intake, behavior toward the advertised product, its purchase or consumption in children and adolescents. Results: Twenty-one systematic reviews fulfilled the inclusion criteria, including a total of 490 primary studies, 5 of which also contained a meta-analysis. The vast majority of the primary studies evaluate intermediate effects, related to the behavior of children and adolescents in relation to advertised products and their consumption. There is great variety in terms of the type of advertising and effects studied. Most of studies agree that there is an association between food advertising and effect analyzed, being more evident in children under 12 years of age and in obese children. Most recent systematic reviews are focused on on-line advertising, noticing the negative effects especially in adolescents. (AU)

Adaptación transcultural al español y validez de contenido de 3 escalas de riesgo nutricional / Cross-cultural adaptation to Spanish and content validity of three nutritional risk scales

Introducción: Existen diversas escalas diseñadas para determinar el riesgo de desnutrición al ingreso hospitalario en población infantil, sin embargo, la mayor parte de estos instrumentos se desarrollan y publican en lengua inglesa, siendo preceptiva su adaptación transcultural y validación para poder ser utilizados en nuestro país.Objetivos: Adaptar transculturalmente 3 escalas diseñadas para determinar el riesgo de desnutrición ligada a la enfermedad y determinar la validez de su contenido.Material y métodos: Adaptación transcultural mediante el método de traducción-retrotraducción de acuerdo con las recomendaciones de la International Test Commission Guidelines for Translating and Adapting Tests. Se midió la validez de contenido a través de un panel de expertos (bajo 7 criterios básicos de selección adaptados del modelo Fehring) que evaluaron cada ítem de las escalas midiendo 4 criterios: ambigüedad, sencillez, claridad y relevancia. Con la puntuación extraída se obtuvo el estadístico V de Aiken para cada ítem y para las escalas completas.Resultados: Partiendo de 3 traducciones independientes por escala se obtuvieron 3 versiones definitivas en castellano de las escalas PNRS, STRONGkids y STAMP semánticamente equivalentes a sus versiones originales. Las escalas PNRS y STRONGkids presentaron una V de Aiken superior a 0,75 en todos sus ítems, mientras que escala STAMP presentó un valor inferior a 0,75 para el ítem «peso y altura».Conclusión: Este estudio aporta las versiones en castellano adaptadas transculturalmente de las escalas PNRS, STRONGkids y STAMP. Las escalas PNRS y STRONGkids presentan un contenido válido para ser aplicadas en el contexto hospitalario estatal. STAMP requiere la adaptación de su ítem «peso y altura» para considerar adecuado su uso en población infantil española. (AU)

Introduction: There are various scales designed to determine the risk of malnutrition at hospital admission in children. However, most of these instruments are developed and published in English. Their cross-cultural adaptation and validation being mandatory in order to be used in our country.Objectives: Cross-culturally adapt three scales designed to determine the risk of malnutrition linked to the disease and determine the validity of their content.Material and methods: Cross-cultural adaptation using the translation-back-translation method in accordance with the recommendations of the International Test Commission Guidelines for Translating and Adapting Tests. Content validity was measured by a panel of experts (under seven basic selection criteria adapted from the Fehring model) who evaluated each item of the scales by measuring 4 criteria: ambiguity, simplicity, clarity and relevance. With the extracted score, Aiken's V statistic was obtained for each item and for the complete scales.Results: Starting from three independent translations per scale, 3 definitive versions in Spanish of the PNRS, STRONGkids and STAMP scales were obtained semantically equivalent to their original versions. The PNRS and STRONGkids scales presented an Aiken's V greater than 0.75 in all their items, while the STAMP scale presented a value less than 0.75 for the item “weight and height”.Conclusion: This study provides the transculturally adapted Spanish versions of the PNRS, STRONGkids and STAMP scales. The PNRS and STRONGkids scales present valid content to be applied in the state hospital context. STAMP requires the adaptation of its item “weight and height” to consider its use in a Spanish child population adequate. (AU)

Cross-cultural adaptation to Spanish and content validity of three nutritional risk scales.

INTRODUCTION: There are various scales designed to determine the risk of malnutrition at hospital admission in children. However, most of these instruments are developed and published in English.

Effects of Kangaroo Mother Care in the NICU on the Physiological Stress Parameters of Premature Infants: A Meta-Analysis of RCTs.

OBJECTIVE: The aim of this study was to analyze the randomised controlled trials that explored the effect of kangaroo mother care on physiological stress parameters of premature infants. METHODS: Two independent researchers performed a systematic review of indexed studies in PubMed, Embase, CINAHL, Cochrane and Scopus. We included data from randomized controlled trials measuring the effects of kangaroo care compared to standard incubator care on physiological stress outcomes, defined as oxygen saturation, body temperature, heart rate and respiratory rate. The PRISMA model was used to conduct data extraction. We performed a narrative synthesis of all studies and a meta-analysis when data were available from multiple studies that compared the same physiological parameters with the kangaroo method as an intervention and controls and used the same outcome measures. RESULTS: Twelve studies were eligible for inclusion in this meta-analysis. According to statistical analysis, the mean respiratory rate of preterm infants receiving KMC was lower than that of infants receiving standard incubator care (MD, -3.50; 95% CI, -5.17 to -1.83; p < 0.00001). Infants who received kangaroo mother care had a higher mean heart rate, oxygen saturation and temperature, although these results were not statistically significant. CONCLUSIONS: Current evidence suggests that kangaroo care in the neonatal intensive care unit setting is a safe method that may have a significant effect on some of the physiological parameters of stress in preterm infants. However, due to clinical heterogeneity, further studies are needed to assess the effects of physiological stress in the neonatal intensive care unit on the development of preterm infants.

Mapping the Field in Stress, Anxiety, and Postpartum Depression in Mothers of Preterm Infants in Neonatal Intensive Care.

OBJECTIVE: The main aim of this study was to describe and conduct a bibliometric analysis of the state of research on stress, anxiety, and postpartum depression in mothers of preterm infants in the Neonatal Intensive Care Unit. BACKGROUND: Women affected by premature births are particularly exposed to mental health difficulties in the postpartum period. The desire to comprehend and the growing interest in research on stress, anxiety, and postpartum depression in mothers of preterm infants in neonatal intensive care have led to a substantial rise in the number of documents in this field over the last years. Thus, it makes it vital to regularly review the state of knowledge on this phenomenon in order to identify progress and constraints, to stimulate reflection, and to encourage progress in future research. METHOD: This study examined 366 articles published in the Scopus database (1976-2020). Keyword analysis was also used to identify hot research trends to be developed in future studies. This study complies with the PRISMA-Scr guidelines for quality improvement research in the EQUATOR network. RESULTS: Our results reveal that research in this field is in a period of high production and allows this flourishing body of work to be organized into different periods, highlighting the most important themes. In such a way, our research enriches the lively field by presenting a comprehensive understanding of the field. DISCUSSION: The key contribution of this study is the development of a conceptual map of research on stress, anxiety, and postpartum depression in mothers of preterm infants in neonatal intensive care units.

Prevalence and associated factors of iron deficiency in Spanish children aged 1 to 11 years.

Iron deficiency (ID) is the most common nutritional deficiency affecting children worldwide. Most traditional laboratory parameters to assess ID can be altered by infections or other inflammatory states, including obesity. The aims of this study were to determine the prevalence of ID in healthy children and to analyse associated factors, avoiding potential confounding factors through the use of serum transferrin receptor (sTfR), reticulocyte haemoglobin content and sTfR/log ferritin index. A cross-sectional population-based study was conducted on 951 children aged 1 to 11 years in Almería (Spain). ID was detected in 7.7% of children and iron deficiency anaemia in 0.9%. Multivariate analysis identified the following as independent risk factors: age under 5 years (OR: 2.2, 95% CI: 1.35-3.6); excessive consumption of cow's milk and dairy products (OR: 1.87, 95% CI: 1.13-3.1); and insufficient consumption of vegetables (OR: 2.7, 95% CI: 1.2-6.1).Conclusions: Using a combination of iron status parameters with greater discriminatory power than classical measures, this study detected a considerable iron deficiency prevalence in Spanish children. Younger children and specific dietary habits exhibit a particular risk for ID, so special attention should be paid to this population. What is Known: • Iron deficiency remains the most prevalent nutritional deficit worldwide, and children aged under 3 years are the most vulnerable to this condition. • Accurate assessment of iron status, based on a combination of biochemical indicators, can often be complicated. What is New: • Iron deficiency continues to present a health problem in Spanish children aged 1 to 11 years, considering the serum transferrin receptor and reticulocyte haemoglobin content for diagnosis. • Excessive consumption of dairy products and low consumption of vegetables are independent risk factors for iron deficiency.

Relationship between Obesity and Iron Deficiency in Healthy Adolescents.

The relationship between overweight/obesity (excess of weight [EW]) and iron deficiency (ID) is not well defined. Objective: To analyze the relationship between EW and ID in healthy adolescents, assessing the contribution of new diagnostic measures of iron status and erythropoietic activity. Method: A cross-sectional study was made of 405 healthy adolescents, 12-16 years of age. A total of 289 were normal weight (NW) and 116 were otherwise healthy EW. Epidemiological, socioeconomic, diet, BMI Z-score, CRP (C-reactive protein), hematological, iron status, and erythropoietic activity parameters were measured. Statistical tests were Student's, analysis of variance (ANOVA), Chi-square, Pearson's correlation, and odds ratio. Results: ID prevalence in the EW group was 22.6% vs. 29.5% in the NW group (p: 0.3). Greater body weight was associated with lower reticulocyte hemoglobin content (CHr) (NW: 31.3 ± 1.7 pg vs. OW: 30.2 ± 1.7 pg, p: 0.007) and greater CRP (NW: 0.1 ± 0.2 mg/dL vs. OW: 0.2 ± 0.18 mg/dL, p < 0.001), leukocytes (NW: 6.69 ± 1.57 × 103/L vs. OW: 7.43 ± 1.63 × 103/L, p < 0.02), platelets (NW: 265.6 ± 58.9 × 103/L vs. OW: 291.8 ± 54.4 × 103/L, p < 0.002), ferritin (NW: 32.1 ± 17.9 ng/mL vs. OW: 42.8 ± 20.3 ng/mL, p: 0.01), serum transferrin receptor (sTfR) (NW: 1.39 ± 0.4 mg/L vs. OW: 1.73 ± 0.45 mg/L, p: 0.008), sTfR-F index (sTfR/log Ferritin) (NW: 1.06 ± 0.7 vs. OW: 1.33 ± 0.85, p: 0.036) and reticulocyte count (NW: 54.2 ± 18 × 103/L vs. OW: 65.4 ± 24.2 × 103/L, p: 0.003). A positive correlation was observed between the BMI Z-score and CRP, ferritin, sTfR, leukocytes, platelets, and reticulocyte count, and a negative one between the BMI Z-score and CHr and medium corpuscular volume. Conclusions: The prevalence of ID in otherwise healthy EW adolescents was no higher than in NW. The effect of obesity on iron status was low. The findings reveal the concomitant low-grade inflammation, and probably the effect of adiposity on erythropoietic activity. Specific cutoff values for ID in adolescents with OW need to be defined.

Predictors of Response to Exclusive Enteral Nutrition in Newly Diagnosed Crohn´s Disease in Children: PRESENCE Study from SEGHNP.

Exclusive enteral nutrition (EEN) has been shown to be more effective than corticosteroids in achieving mucosal healing in children with Crohn´s disease (CD) without the adverse effects of these drugs. The aims of this study were to determine the efficacy of EEN in terms of inducing clinical remission in children newly diagnosed with CD, to describe the predictive factors of response to EEN and the need for treatment with biological agents during the first 12 months of the disease. We conducted an observational retrospective multicentre study that included paediatric patients newly diagnosed with CD between 2014-2016 who underwent EEN. Two hundred and twenty-two patients (140 males) from 35 paediatric centres were included, with a mean age at diagnosis of 11.6 ± 2.5 years. The median EEN duration was 8 weeks (IQR 6.6-8.5), and 184 of the patients (83%) achieved clinical remission (weighted paediatric Crohn's Disease activity index [wPCDAI] < 12.5). Faecal calprotectin (FC) levels (µg/g) decreased significantly after EEN (830 [IQR 500-1800] to 256 [IQR 120-585] p < 0.0001). Patients with wPCDAI ≤ 57.5, FC < 500 µg/g, CRP >15 mg/L and ileal involvement tended to respond better to EEN. EEN administered for 6-8 weeks is effective for inducing clinical remission. Due to the high response rate in our series, EEN should be used as the first-line therapy in luminal paediatric Crohn's disease regardless of the location of disease and disease activity.

Reference Values of Reticulocyte Hemoglobin Content in Healthy Adolescents.

Assessing iron status in a pediatric population is not easy, as it is based on parameters that undergo physiological variations in childhood and adolescence. Analysis of the reticulocyte hemoglobin content (CHr) to screen for iron deficiency may increase the accuracy of diagnosis, but, to date, reference values in healthy adolescents have not been adequately determined. A cross-sectional study was conducted on a population-based representative sample in the city of Almería (Spain), with 253 healthy non-iron-deficient (ID) subjects, aged 12 to 16 years. The mean CHr value was 31.6±1.3 pg. The CHr 2.5 percentile was 28.7 pg. There were no significant differences as regards age or sex. In the multivariate linear regression analysis, sex did not influence the variability of CHr, but it was related to age. CHr was influenced by hemoglobin and the Mentzer index, as well as by functional iron indicators such as erythrocyte protoporphyrin and serum transferrin receptor. These independent variables predicted two thirds of the variability in healthy adolescents (R=0.55). This study provides CHr reference ranges in healthy adolescents for use in clinical practice for the early detection of ID states. In populations with similar sociodemographic characteristics, values above the 2.5 percentile rule out ID, as values under the 2.5 percentile could be suggestive of functional ID.

Insulinaemia and insulin resistance in Caucasian general paediatric population aged 2 to 10 years: Associated risk factors.

BACKGROUND: The aim of this study is to determine values of insulinaemia, homeostasis model assessment (HOMA) index and quantitative insulin sensitivity check index (QUICKI) among a population of prepubertal Caucasian children, to analyse factors associated with insulin resistance (IR), and to study its association with cardiovascular risk factors. MATERIALS AND METHODS: Population-based study conducted on a randomly selected sample of prepubescent Caucasian subjects aged 2.00 to 9.99 years old. Anthropometric measurements, blood pressure, and fasting blood samples were obtained, including fasting glucose, triglycerides, High Density Lipoprotein (HDL)-cholesterol, and insulin. In addition, QUICKI and HOMA indices were calculated. Generalised additive models for location, scale and shape (GAMLSS) was used to calculate centiles curves and multivariate logistic regression analysis to assess factors associated with IR. RESULTS: A total of 654 subjects were included. Mean values obtained for insulinaemia, HOMA index, and QUICKI were 3.74 µIU/mL, 0.73, and 0.44, respectively, in the overall population and 3.32 µIU/mL, 0.64 and 0.46, respectively, in normal weight subjects. The main factor associated with IR was abdominal obesity (odds ratio [OR] 3.38 [95% CI 1.44-7.94] in the subgroup aged 2.00-5.99 years and OR 9.14 [3.42-24.41] for those aged 6.00-9.99 years). An increased risk of hyperglycaemia (P = 0.043), hypertriglyceridaemia (P < .001), and HDL < p10 (P = 0.021) was described among children aged 2.00 to 5.99 years with IR, and among those aged 6.00 to 9.99 years, IR was associated with an increased risk of hypertriglyceridaemia (P < .001). CONCLUSION: Abdominal obesity was the main factor associated with IR. Metabolic changes associated with IR seem to be present from early stages of life, which highlights the importance of the prevention, early diagnosis and treatment of obesity.

Reproducibility and Inter-rater Reliability of 2 Paediatric Nutritional Screening Tools.

OBJECTIVES: The aim of the present study was to assess reproducibility and inter-rater reliability of 2 nutritional screening tools (NST): Screening Tool for Risk on Nutritional Status and Growth (STRONGkids) and Screening Tool for the Assessment of Malnutrition in Paediatrics (STAMP). METHODS: Prospective observational multicentre study. Patients ages 1 month or older admitted to paediatric or surgical wards were tested within 24 hours of admission by 2 independent observers: experts specialized in paediatric nutrition (physicians or dieticians) and clinical staff nonexpert in nutrition. Diagnosis on admission, underlying diseases, and length of stay were registered. STATISTICAL ANALYSIS: Kappa index (κ) to evaluate agreement between observers. RESULTS: A total of 223 patients were included (53.4% boys), with mean age of 5.59 (95% confidence interval 4.94-6.22) years. Experts classified 9.9% of patients at high risk with STRONGkids and 19.7% using STAMP, whereas nonexpert staff assigned 6.7% of patients to the high-risk category with STRONGkids and 21.9% with STAMP. Agreement between expert and nonexpert staff was good: 94.78% for STRONGkids (κ 0.72 [P < 0.001]); 92.55% for STAMP (κ 0.74 [P < 0.001]). The rate of malnutrition was significantly higher among high-risk patients with both NST, independent of examiner experience. After adjusting for age, both STRONGkids and STAMP high-risk scores predicted longer length of stay, whether assessed by experts or nonexperts, although differences were higher with STRONGkids. CONCLUSIONS: Agreement between experts and nonexpert staff in nutrition was good, producing a similar high-risk patient profile. Our results demonstrate that these NSTs are appropriate for nutritional screening in settings in which users have no previous experience in the field.

Nutrición parenteral en situaciones clínicas especiales / No disponible

La nutrición parenteral (NP) constituye un pilar fundamental en la nutrición del recién nacido (RN) prematuro, especialmente en el RN muy prematuro (< 32 semanas de gestación) y RN prematuro extremo (< 28 semanas de gestación). En estos pacientes, la administración de una NP balanceada y precoz se considera de elección. Dos metaanálisis han demostrado que la NP precoz en el RN prematuro < 1.500 g es segura, sin aumentar el riesgo de efectos adversos (3,4), y ha mostrado beneficios en relación con un balance nitrogenado positivo (ver aporte proteico) y mayor ganancia ponderal respecto a controles, aunque no se ha observado mayor longitud o perímetro craneal al alta en el grupo de intervención. Cabe destacar que los ensayos clínicos analizados cuentan con pequeño tamaño muestral y son heterogéneos (AU)

Reference Values of Reticulocyte Hemoglobin Content and Their Relation With Other Indicators of Iron Status in Healthy Children.

Reticulocyte hemoglobin content (CHr) is considered an indicator of functional iron deficiency, but is understudied in children. The goals of this study are to determine the reference intervals for CHr in healthy children, and their relation with iron parameters, erythropoiesis, and individual conditions. A total of 902 children without iron deficiency, aged 1 to 11 years were analyzed in a cross-sectional study. Besides a physical examination of the subjects and a questionnaire completed by their parents, the complete blood count, serum transferrin receptor, ferritin, transferrin saturation, erythrocyte protoporphyrin, serum erythropoietin, C-reactive protein, and CHr levels were measured. Changes in CHr, iron status, and erythropoiesis at different age intervals were analyzed and linear multiple regression was used to identify the factors that determine CHr variability. Mean value obtained for CHr was 30.9±1.8 pg (P2.5-P97.5: 26.9 to 34.3 pg), but the influence of age on CHr (the values increased with age) and on the iron parameters justified the establishment of different reference ranges. In addition to age, nutritional status, hematologic measurements, reticulocytes, transferrin saturation, and erythrocyte protoporphyrin accounted for 39% of CHr variability.

Thyroid Function and Thyroid Autoimmunity in Relation to Weight Status and Cardiovascular Risk Factors in Children and Adolescents: A Population-Based Study.

OBJECTIVE: In obese subjects, slight increases have been observed in thyrotropin [thyroid-stimulating hormone (TSH)] levels, but data in children are scarce. The aim of this study was to evaluate whether thyroid function and autoimmunity vary with weight status in a healthy population of children and adolescents and to determine whether hyperthyrotropinemia is associated with any cardiovascular risk factor. METHODS: This cross-sectional epidemiological study was conducted in Almería (Spain) on a representative sample of 1317 healthy subjects aged 2-16 years. Thyroid function, thyroid autoimmunity and cardiovascular risk factors were measured. Chi-square test, analysis of variance and multiple linear regression were used in the statistical analyses. RESULTS: The obese children and adolescents had thyrotropin levels (mean ± standard deviation) of 3.12±2.44 mU/L. These levels were higher than those of overweight subjects (2.79±1.51 mU/L) and of normal weight subjects (2.73±1.30 mU/L) (p=0.02). Levels of free thyroxine and urinary iodine did not differ significantly between the groups. The prevalence (95% confidence interval) of thyroid autoimmunity was lower in the individuals with normal weight (2.9%; 2.0-4.2) than in the overweight (6.3%; 3.9-9.9) and obese subjects (5.6%, 2.5-11.3) (p=0.02). TSH levels were associated with obesity (ß=0.36; p<0.001) and thyroid autoimmunity (ß=1.10; p<0.001). They were not associated with any cardiovascular risk factor. CONCLUSION: Obese children and adolescents had higher levels of thyrotropin than those who were overweight and of normal weight. The differences among the groups were of very little clinical significance and could possibly be linked to the higher prevalence of thyroid autoimmunity in obese subjects. The hyperthyrotropinemia in these subjects was not associated with any cardiovascular risk factor.
