Predictors of adherence to follow-up and treatment success in childhood obesity.

INTRODUCTION: Management of childhood obesity, based upon behavioural, physical activity and dietary guidance, usually achieves limited success and is hindered by a high attrition rate. The identification of potential predictors of either weight loss or early weight management attrition could help develop personalised management plans in order to improve patient outcomes. PATIENTS AND METHODS: We conducted a retrospective study in a cohort of 1300 patients with obesity managed in speciality clinics for up to 5 years with outpatient conservative treatment. We studied the family background and personal characteristics (demographic, behavioural, psychosocial, anthropometric and metabolic) of patients who dropped out before completing the first year of the programme and patients who achieved significant weight loss, with a separate analysis of patients who achieved substantial reductions in weight compared to the rest of the cohort. RESULTS: The mean age of the patients in the cohort was 10.46 years (SD, 3.48) the mean BMI z-score 4.01 (SD, 1.49); 52.8% of the patients were male, 53.3% were prepubertal, 75.8% were Caucasian and 19% Latin. We found a higher proportion of Latinla ethnicity and compulsive eating in the group of patients with early attrition from the weight management follow-up. In the group of patients with substantial weight loss, a greater proportion were male, there was a higher frequency of dietary intake control at home and obesity was more severe, and the latter factor was consistently observed in patients who achieved substantial weight loss at any point of the follow-up. CONCLUSIONS: Some family and personal characteristics in childhood obesity are associated with an increased risk of early withdrawal from follow-up or a greater probability of successful outcomes; however, the predictive value of these variables is limited.

Prevalence of childhood obesity in Spain and its relation with socioeconomic status and health behaviors: Population-based cross-sectional study.

OBJECTIVES: This study aims to assess the current state of childhood overweight and obesity in Spain, and its relationship with socioeconomic status and health-related behaviors. METHODS: Population-based cross-sectional observational study, based on the 2017 National Health Survey in minors in Spain. This study included all children surveyed who were aged 1-14 years. Childhood obesity was estimated from the z-score of the body mass index. RESULTS: The study included 4882 children aged 1-14 years (mean 7.5). The prevalence of obesity was 18.6% (95% confidence interval [CI] 18.5-18.7), while 13.5% (95% CI 13.4-13.6) were overweight. These figures represent over a million children in Spain who are obese and nearly 750,000 who are overweight. A north-south geographic gradient was apparent, with higher prevalence of unhealthy body weight in southern Spain. Factors associated with childhood obesity were low socioeconomic status, poor diet and sedentarism, among others. CONCLUSIONS: Childhood overweight in Spain is strongly associated with socioeconomic status and other factors such as diet and sedentarism. Multidisciplinary public health interventions are needed to reduce this serious health problem in children.

[Cardiometabolic effects of weight loss]. / Efectos cardiometabólicos de la pérdida de peso.

The prevalence of overweight and obesity, and, consequently, associated comorbidities, is increasing significantly worldwide. The guidelines recommend a percentage of weight loss> 5% to achieve beneficial effects on metabolic comorbidities associated with obesity. Furthermore, greater weight losses (> 10%) produce more significant improvements, and may even produce remission of some of these comorbidities. In this chapter, we review the evidence of the effect of weight loss through different strategies (lifestyle intervention, pharmacological treatment, or bariatric surgery) on the main cardiometabolic pathologies associated with excess adipose tissue (type 2 diabetes, high blood pressure, dyslipidemia, metabolic dysfunction-associated steatotic liver disease, inflammation, cardiovascular diseases, and mortality).

Risk factors associated with COVID-19 mortality in Mexico.

BACKGROUND: On December 31, 2019, one of the most serious pandemics in recent times made its appearance. Certain health conditions, such as obesity and diabetes mellitus, have been described to be related to COVID-19 unfavorable outcomes. OBJECTIVE: To identify factors associated with mortality in patients with COVID-19. MATERIAL AND METHODS: Retrospective cohort of 998,639 patients. Patient sociodemographic and clinical characteristics were analyzed, with survivors being compared with the deceased individuals. Cox proportional hazards model was used to identify variables predictive of COVID-19-associated mortality. RESULTS: Among the deceased patients, men accounted for 64.3%, and women, for 35.7%, with the difference being statistically significant. Subjects older than 80 years had a 13-fold higher risk of dying from COVID-19 (95% CI = 12,469, 13,586), while chronic kidney disease entailed a risk 1.5 times higher (95% CI = 1,341, 1,798), and diabetes mellitus involved a risk 1.25 times higher (95% CI = 1.238,1.276). CONCLUSIONS: Age, sex, diabetes mellitus and obesity were found to be predictors of COVID-19 mortality. Further research related to chronic obstructive pulmonary disease, cardiovascular diseases, smoking and pregnancy is suggested.

ANTECEDENTES: El 31 de diciembre de 2019, se inició una de las pandemias más graves de los últimos tiempos. Se ha descrito que ciertas condiciones de salud, como la obesidad y la diabetes mellitus, están relacionadas con desenlaces desfavorables por COVID-19. OBJETIVO: Identificar factores asociados a mortalidad en pacientes con COVID-19. MATERIAL Y MÉTODOS: Cohorte retrospectiva de 998 639 pacientes. Se analizaron las características sociodemográficas y clínicas de los pacientes, y se compararon supervivientes con fallecidos. Se utilizó el modelo de riesgos proporcionales de Cox para la identificación de variables predictivas de defunción por COVID-19. RESULTADOS: Entre los fallecidos, los hombres representaron 64.3 % y las mujeres 35.7 %, diferencia que resultó estadísticamente significativa. Las personas con más de 80 años presentaron un riesgo 13 veces mayor de morir por COVID-19 (IC 95 % = 12.469,13.586) y la enfermedad renal crónica, un riesgo de 1.5 (IC 95 % = 1.341, 1.798); la diabetes mellitus tuvo un riesgo de 1.25 (IC 95 % = 1.238,1.276). CONCLUSIONES: La edad, el sexo, la diabetes mellitus y la obesidad resultaron ser entidades predictivas de muerte por COVID-19. Se sugiere más investigación relacionada con enfermedad pulmonar obstructiva crónica, enfermedades cardiovasculares, tabaquismo y embarazo.

Diagnosis of nutritional status, dyslipidemia and associated risk factors in indigenous Yaqui schoolchildren.

BACKGROUND: Malnutrition is a global problem that affects schoolchildren and can increase the risk of diseases in adulthood. Adult members of the Yaqui Indigenous group have been shown to have serious health problems, and Yaqui schoolchildren could therefore find themselves in a similar situation. OBJECTIVE: To evaluate the nutritional status, lipid profile and associated factors in a sample of Yaqui schoolchildren. MATERIAL AND METHODS: A total of 109 Yaqui schoolchildren who lived in their localities of origin were recruited. Anthropometric measurements were carried out, a venous blood sample was extracted in fasting conditions, and several questionnaires were applied. RESULTS: The prevalence of overweight/obesity was 38.5%, with no cases of chronic malnutrition being recorded; 38.6% of the children had dyslipidemia. Fiber consumption was a protective factor against overweight/obesity, while fat intake was a risk factor. The physical activity score was found to be a protective factor against dyslipidemia, and the risk factors were BMI-for-age Z-scores, waist circumference, family history of dyslipidemia, educational level, and permanent employment. CONCLUSIONS: Yaqui schoolchildren equally suffer from a high proportion of overweight/obesity and dyslipidemia. The associated factors may be useful for the design of contextualized interventions for this population.

ANTECEDENTES: La malnutrición es un problema mundial que afecta a niños escolares, capaz de incrementar el riesgo de enfermedades en la edad adulta. Adultos yaquis han presentado graves problemas de salud, por lo que los escolares podrían encontrarse en una situación similar. OBJETIVO: Evaluar el estado nutricional, el perfil lipídico y los factores asociados en una muestra de escolares yaquis. MATERIAL Y MÉTODOS: Se estudiaron 109 escolares habitantes de los pueblos originarios, en quienes se realizaron mediciones antropométricas, se extrajo una muestra de sangre venosa en condición de ayuno y se aplicaron cuestionarios. RESULTADOS: La prevalencia de sobrepeso/obesidad fue de 38.5 %, sin que se registraran casos de desnutrición crónica; 38.6 % de los escolares presentó dislipidemia. El consumo de fibra resultó ser un factor protector contra sobrepeso/obesidad y el consumo de grasa constituyó un factor de riesgo. La puntuación de actividad física resultó ser un factor protector contra dislipidemia y los factores de riesgo fueron puntuaciones Z del índice de masa corporal/edad, circunferencia de cintura, historia familiar de dislipidemias, nivel educativo y empleo permanente. CONCLUSIONES: Los escolares yaquis padecen por igual alta proporción de sobrepeso/obesidad y dislipidemia. Los factores asociados pueden resultar útiles para el diseño de intervenciones contextualizadas para esta población.

[Strategies for the prevention and non-pharmacological treatment of obesity. Models of care]. / Estrategias para la prevención y el tratamiento no farmacológico de la obesidad. Modelos de atención.

The prevalence of obesity has increased in recent years worldwide. In this context, strategies for management obesity in primary care are essential. The first step in the treatment of obesity are lifestyle intervention programs. The three pillars of these programs, ideally of high intensity (high frequency of visits), are dietary intervention, exercise and behavioral therapy. There is no universal model of care for patients with obesity, but it must take into account key aspects, such as facilitating the access and adherence of the patient and a multidisciplinary and coordinated care among professionals at different levels of healthcare. The components of the model of care and its format should be defined according to the resources available and the characteristics of the population to be treated.

[When should a patient with obesity be referred to endocrinology? Current indications for bariatric surgery]. / ¿Cuándo derivar a endocrinología el paciente con obesidad? Indicaciones actuales de la cirugía bariátrica.

Bariatric surgery (BS) has been shown to be effective and efficient, but only 1% of selected patients will ever receive it. Compared to medical treatment of obesity, BS has demonstrated greater long-term sustained weight loss, a reduction in both total and cardiovascular (CV) mortality, improvement or remission of CV risk factors and other comorbidities associated with obesity, as well as improved mobility and quality of life. BS presents similar risks to other abdominal surgeries, with obesity as an added risk factor. However, mortality after this type of surgery is less than 1%, being in specialised centres even lower than 0.3%, with a morbidity of less than 7%. The most commonly performed surgical procedures at present are vertical gastrectomy and Roux---Y gastric bypass, preferably by laparoscopic approach.

Frailty, Sarcopenia and Osteoporosis. / Fragilidad, sarcopenia y osteoporosis.

Frailty, sarcopenia and osteoporosis are entities specific to the elderly, who share some risk factors. For this reason, their relationship has been studied in different works, which have provided disparate results, probably because these studies have not always focused on the same aspects. This article reviews the relationship of frailty and sarcopenia with osteoporosis.

Impacto de la pandemia por SARS-CoV-2 en el índice de masa corporal de niños asistidos en la Ciudad Autónoma de Buenos Aires / Impact of the SARS-CoV-2 pandemic on the body mass index of children seen in the City of Buenos Aires

Introducción. El sobrepeso y la obesidad infantil constituyen un problema de salud pública. El inicio de la pandemia por COVID-19 pudo haber favorecido esta patología. El puntaje Z del índice de masa corporal (Z-IMC) es un indicador aceptado para su diagnóstico y seguimiento. Objetivo. Evaluar si la prevalencia de sobrepeso y obesidad, y el Z-IMC en niños de 2 a 5 años aumentó durante la pandemia. Población y métodos. Estudio de cohorte retrospectiva. Se incluyeron pacientes asistidos en efectores públicos de salud del Gobierno de la Ciudad Autónoma de Buenos Aires (GCABA), de 2 a 5 años de edad, con registro de peso y talla en dos consultas, antes y después de haber comenzado el aislamiento social preventivo y obligatorio (ASPO). Se registró estado nutricional (Z-IMC) y variación del Z-IMC entre ambas consultas. Resultados. Se evaluaron 3866 sujetos, edad promedio 3,4 ± 0,8 años; el 48,1 % fueron mujeres. El intervalo promedio entre consultas fue 14,3 ± 2,5 meses. La prevalencia de sobrepeso/obesidad aumentó del 12,6 % (IC95% 11,6-13,6) al 20,9 % (IC95% 19,6-22-2); p <0,001, al igual que el Z-IMC (0,4 ± 1,1 vs. 0,8 ± 1,3; p <0,001). Conclusión. La prevalencia de sobrepeso y obesidad, y el Z-IMC en niños de 2 a 5 años aumentó significativamente durante la pandemia.

Introduction. Childhood overweight and obesity are a public health problem. The onset of the COVID-19 pandemic may have contributed to this condition. The body mass index (BMI) Z-score has been accepted as an indicator for overweight and obesity diagnosis and follow-up. Objective. To assess whether the prevalence of overweight and obesity and the BMI Z-score in children aged 2 to 5 years increased during the pandemic. Population and methods. Retrospective, cohort study. Patients included were those seen at public health care facilities in the City of Buenos Aires (CABA), who were aged 2 to 5 years, had weight and height values recorded at 2 different visits, before and after the establishment of the preventive and mandatory social isolation policy. Patients' nutritional status (BMI Z-score) and the variation in this indicator between both visits were recorded. Results. A total of 3866 subjects were assessed; their average age was 3.4 ± 0.8 years; 48.1% were girls. The average interval between both visits was 14.3 ± 2.5 months. The prevalence of overweight/ obesity increased from 12.6% (95% CI: 11.6­13.6) to 20.9% (95% CI: 19.6­22.2), p < 0.001, and so did the BMI Z-score (0.4 ± 1.1 versus 0.8 ± 1.3, p < 0.001). Conclusion. The prevalence of overweight and obesity and the BMI Z-score in children aged 2 to 5 years increased significantly during the pandemic.

Resultados cardiometabólicos de largo plazo tras cirugía bariátrica: control de comorbilidades, pérdida y reganancia de peso a los 5 años de seguimiento / Long-term cardiometabolic results after bariatric surgery: Control of comorbidities, weight loss and regain at 5 years of follow-up

Introducción. La cirugía bariátrica y metabólica (CBM) es efectiva en lograr pérdida de peso a corto plazo. Sin embargo, existe evidencia limitada en desenlaces clínicos y metabólicos a largo plazo. Métodos. Estudio longitudinal retrospectivo con pacientes llevados a baipás gástrico en Y de Roux (BGYR) o gastrectomía en manga (MG) por laparoscopia en Bogotá, D.C., Colombia, entre 2013 y 2021. El cambio de peso, control de comorbilidades y resultados metabólicos se recopilaron al inicio del estudio, 3, 6 y 12 meses después de cirugía, y anualmente hasta el quinto año. Las tasas de control de comorbilidades se evaluaron mediante la prueba Kaplan-Meier. Se utilizó un modelo de riesgos proporcionales de Cox para evaluar el efecto de covariables en la reganancia de peso. Resultados. De 1092 pacientes con CBM (71,4 % MG y 28,6 % BGYR), 67 % eran mujeres, con mediana de edad 48 años e índice de masa corporal de 35,5 Kg/m2. Después de cinco años de seguimiento, la tasa de control en diabetes mellitus fue 65,5 %, en hipertensión 56,6 % y en dislipidemia 43,6 %. La tasa de reganancia de peso fue 28 %, sin diferencias entre MG vs BGYR (p=0,482). El tiempo promedio hasta peso nadir fue 14 meses. La edad al momento de CBM fue el mejor predictor independiente de reganancia (HR=1,02, IC95% 1,01-1,04), pero con efecto clínico modesto. Conclusión. La CBM es segura y muestra beneficios a largo plazo en la pérdida de peso y control de comorbilidades en población colombiana.

Introduction. Bariatric and metabolic surgery (BMS) has shown its efficacy in achieving short-term weight loss. However, there is limited evidence regarding long-term clinical and metabolic outcomes. Methods. Retrospective longitudinal study with patients who underwent laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) interventions in Bogotá, Colombia, between 2013 and 2021. Weight change, comorbidity control, and metabolic outcomes were collected at the onset, 3-, 6-, and 12-month post-surgery, and annually up to the fifth year. Comorbidity control rates were assessed using the Kaplan-Meier test. A Cox proportional hazards model was used to evaluate the effect of covariates on weight regain. Results. Of 1092 patients with BMS (71.4% SG and 28.6% RYGB), 67% were women, with a median age of 48 years, BMI 35.5 kg/m2. After five years of follow-up, the control rate in diabetes mellitus was 65.5%, in hypertension 56.6%, and dyslipidemia 43.6%. The weight regain rate was 28% with no differences between SG vs RYGB (p=0.482). The mean time to nadir weight was 14 months. Age at the time of BMS was the best independent predictor of weight regain (HR=1.02, 95%CI: 1.01-1.04), but with a modest clinical effect. Conclusion. BMS is safe and shows long-term benefits in weight loss and control of comorbidities in Colombian population.

O papel da escola e da Educação Física no controle do sobrepeso e obesidade juvenil na perspectiva de professores atuantes no ensino superior / The role of schools and Physical Education in the control of overweight and juvenile obesity from the perspective of teachers working in higher education / El papel de las escuelas y la Educación Física en el control del sobrepeso y la obesidad juvenil desde la perspectiva de docentes que trabajan en la educación superior

O presente artigo apresenta os resultados de uma pesquisa quantitativa com viés exploratório descritivo, cujo objetivo foi analisar a percepção de 22 professores de Educação Física (18 homens e 04 mulheres), atuantes no magistério superior, sobre o papel da escola e da Educação Física no controle do sobrepeso e obesidade juvenil. Foi utilizada versão adaptada do Perceptions of Youth Obesity and Physical Education Questionnaire. A análise dos dados deu-se a partir das seguintes categorias: percepção da obesidade juvenil, papel da escola e papel da Educação Física permitiu inferir que os professores percebem a escola como um espaço potencial para a promoção de ações, como a oferta de disciplinas curriculares voltadas ao controle do peso corporal. Contudo, tanto a escola, quanto o professor e sua práxis nas aulas de Educação Física não devem restringir as intervenções de forma circunscrita ao tratamento e controle da obesidade juvenil (AU).

This article presents the results of a quantitative research with a descriptive exploratory bias, whose objective was to analyze the perception of 22 Physical Education teachers (18 men and 04 women), working in higher education, about the role of school and Physical Education in controlling overweight and juveni-le obesity. An adapted version of the Perceptions of Youth Obesity and Physical Education Questionnaire was used. The analysis of the data from the categories called perception of youth obesity, role of the school and role of Physical Education allowed inferring that teachers perceive the school as a potential space for the promotion of actions, such as the offer of curricular disciplines aimed at controlling the body weight. However, both the school and the teacher and their practice in Physical Education classes should not limit interventions to the treatment and control of juvenile obesity (AU).

Este artículo presenta los resultados de una investigación cuantitativa con sesgo exploratorio descriptivo, cuyo objetivo fue analizar la percepción de 22 profesores de Educación Física (18 hombres y 04 mujeres), que actúan en la enseñanza superior, sobre el papel de la escuela y la Educación Física en el control so-brepeso y obesidad juvenil. Se utilizó una versión adaptada del Cuestionario de Percepciones de Obesidad Juvenil y Educación Física. El análisis de los datos de las categorías denominadas per-cepción de la obesidad juvenil, rol de la escuela y rol de la Educación Física permitió inferir que los docentes perciben la escuela como un espacio potencial para la promoción de acciones, como la ofer-ta de disciplinas curriculares dirigidas al control el peso corporal. Sin embargo, tanto la escuela como el docente y su práctica en las clases de Educación Física no deben limitar las intervenciones al tratamiento y control de la obesidad juvenil (AU).

Effect of semaglutide on weight loss and glycaemic control in patients with Prader-Willi Syndrome and type 2 diabetes.

Prader-Willi Syndrome (PWS) is the most common genetic cause of obesity, occurring in approximately 1 in 15,000 newborns. It results from the lack of expression of genes on the paternal allele of the chromosomal region 15q-11q13 (65-75% due to type 1 or type 2 deletion). Individuals with PWS experience associated symptoms such as hypotonia, hyperphagia, and early-onset obesity (before 5 years of age). Around 20% of adults with PWS also develop type 2 diabetes. Previous studies have shown the beneficial effects of GLP1-RA medications, such as exenatide and liraglutide, in treating type 2 diabetes in PWS. However, there is limited information available on the use of semaglutide in PWS. This study aimed to evaluate the effects of semaglutide on weight loss and glycaemic control in four patients with PWS and type 2 diabetes associated with obesity. The patients were started on weekly subcutaneous progressive doses of semaglutide.

Risk factors associated with glomerular filtration rate in Mexican adults with type 2 diabetes mellitus.

INTRODUCTION: Type 2 diabetes mellitus (T2DM) is related to glomerular filtration rate (GFR) impairment, which is one of the main causes of chronic kidney disease. The objective of this study was to identify the risk factors related to GFR in Mexican adults with T2DM, using a validated multiple linear regression model (MLRM), with emphasis in body adiposity, glycemic control, duration of the diabetes and other relevant risk factors. MATERIALS AND METHODS: A cross-sectional, analytical, and observational study was carried out in 252 adults with a previous diagnosis of T2DM. Body mass index (BMI) and waist circumference (WC) were determined and a fasting blood sample was collected for glucose, creatinine and HbA1c determinations. GFR was calculated with the Cockcroft-Gault equation adjusted for body surface area. Four MLRM were performed to determine the factors related to the GFR; it was evaluated whether these models complied with the statistical assumptions of the linear regression model. RESULTS: The average age of the participants was 60 ±â€¯12 years, 62.3% of them were women. GFR correlated with BMI and WC; age and duration of the diabetes were associated inversely. Model 4 of the MLRM reported a coefficient of determination of 53.5% where the variables BMI (ß = 1.31), male sex (ß = -6.01), duration of T2DM (ß = -0.57), arterial hypertension (ß = -6.53) and age (ß = -1.45) were simultaneously and significantly related to the GFR. CONCLUSIONS: Older age, male sex, longer duration of T2DM and the presence of arterial hypertension were associated with a decrease in the GFR; BMI and WC were directly associated. No effect of glucose and HbA1c on GFR was observed.

Differences in the temporal trends of childhood overweight and obesity in Spain in the 2011-2019 period by sex, age and socioeconomic level: results of the ALADINO study.

INTRODUCTION: Childhood excess weight is a growing public health problem. The aim of this study was to assess temporal trends in the prevalence of overweight, obesity and central obesity in schoolchildren aged 6-9 years in Spain between 2011 and 2019 based on demographic and socioeconomic characteristics. METHODOLOGY: The analysis included data from the 2011, 2015 and 2019 rounds of the cross-sectional observational and descriptive ALADINO study in schoolchildren of both sexes aged 6-9 years. We conducted a descriptive analysis of the trends in the prevalence of overweight and obesity (defined according to the criteria of the World Health Organization and the International Obesity Task Force) and of central obesity, in addition to associated demographic and socioeconomic variables. RESULTS: Between 2011 and 2019, the prevalence of overweight (WHO criteria) decreased in boys aged 6, 7 and 8 years (by -5.4%, -5.7% and -5.3%, respectively) and boys whose parents had a higher educational attainment (by -5.3%). In relation to the socioeconomic level, overweight in boys declined at all income levels. However, between 2011 and 2019, both the prevalence of overweight in girls and the prevalence of obesity (applying the WHO and IOTF criteria) and the prevalence of central obesity in both sexes remained stable. CONCLUSIONS: The prevalence of overweight and the prevalence of obesity in schoolchildren aged 6-9 years in Spain remain high. Between 2011 and 2019, the prevalence of overweight in children aged 6-8 years and in children whose parents had university degrees decreased, whereas obesity in boys, overweight and obesity in girls and central obesity in both sexes remained stable.

Ingesta de calcio y vitamina D: relación con exceso de peso en población costarricense / Calcium and vitamin D intake, its relationship with weight excess in Costa Rican population

Introducción: La presencia de sobrepeso y obesidad aumentan la morbimortalidad de la población latinoamericana. La deficiencia de micronutrientes como el calcio y la vitamina D se han relacionado con un aumento del riesgo de obesidad. Objetivo: Determinar la relación entre la ingesta de vitamina D y de calcio con los factores de riesgo para obesidad en la población urbana costarricense incluidas en el Estudio ELANS. Materiales y métodos: Se incluyeron 798 participantes costarricenses del Estudio ELANS. Se determinó la distribución del consumo de calcio y vitamina D según las características socioeconómicas, la actividad física y los datos antropométricos. Se compararon los grupos con las pruebas U de Mann ­ Whitney y Kruskal-Wallis. Se realizaron modelos de regresión lineal y logística. Resultados: El consumo de calcio y vitamina D fue inadecuado en más del 98% de los participantes. Las mujeres, las personas con menor nivel socioeconómico, baja actividad física, de menor edad, con exceso de peso y obesidad abdominal presentaron un consumo menor de calcio y de vitamina D. El consumo de calcio y vitamina D es mayor en los grupos que tienen un menor IMC (p= 0,023 para calcio y p= 0,252 para vitamina D). Las personas con menor circunferencia de la cintura tuvieron más consumo de calcio y vitamina D (p= 0,002 para calcio y p= 0,008 para vitamina D). No hubo asociación del consumo en los modelos de regresión. Conclusiones: El consumo de calcio y vitamina D es deficiente en la población urbana costarricense y, presentó una relación inversa con el IMC(AU)

ntroduction: The presence of overweight and obesity increase the morbimortality of people in Latin America. Micronutrient deficiencies, such as calcium and vitamin D, are associated with an increased risk of obesity. Objective: To determine the relationship between vitamin D and calcium intake with risk factors for obesity in the Costa Rican urban population included in the ELANS Study. Materials and methods: For this analysis we used the 798 Costa Rican participants of the study (ELANS). The distribution of calcium and vitamin D intake was determined according to socioeconomic status, physical activity, and anthropometric measures. The Mann ­ Whitney and Kruskal-Wallis U tests were used, as well as linear and logistic regression models were performed. Results: Calcium and vitamin D intake was inadequate in more than 98% of the participants. Women, individuals with a lower socioeconomic level, low physical activity, younger age and those with excess weight and abdominal obesity presented lower consumptionofcalciumandvitamin D. Theconsumption of calcium and vitamin D was greater in the groups that have a lower BMI (p= 0.023 for calcium and p= 0.252 for vitamin D). The smaller the waist circumference, the greater the consumption of calcium and vitamin D (p= 0.002 for calcium and p= 0.008 for vitamin D). No association of the consumption of calcium and vitamin D was found in the regression models. Conclusions: Consumption of calcium and vitamin D is deficient in the Costa Rican urban population, and more prevalent among those with higher BMI. Arch Latinoam Nutr 2024(AU)

Comparison of abdominal adipose tissue versus body mass index (BMI) as a predictor of complications and survival in liver transplantation.

INTRODUCTION: Because of the obesity epidemic, more obese patients are on liver transplant (LT) waiting lists. The diseases associated with obesity may increase complications and limit survival after LT. However, there is no established measure or cut-off point to determine this impact and aid decision making. The aim of the present study is to evaluate obesity in patients undergoing LT via BMI and CT-based measurement of adipose tissue (AAT). These parameters will be used to predict the risk of postoperative complications and 5-year survival. METHODS: A retrospective, single-center study was carried out at a tertiary Spanish hospital, including all patients who received LT between January 2012 and July 2019 (n = 164). The patients were adults who underwent LT using the 'piggyback' technique, preserving the recipient vena cava. Visceral adipose tissue (VAT) and BMI were calculated to examine correlations with postoperative complications and 5-year survival. RESULTS: No significant association was found between postoperative complications by Comprehensive Complication Index, BMI, AAT/height, subcutaneous fat/height and VAT/height. Kaplan-Meier curves for 5-year survival compared LT recipients with BMI < 30.45 versus ≥30.45, with an estimated survival of 58.97 months versus 43.11 months, respectively (P < .001) (Fig. 3) and for LT recipients with an AAT/height <27.35 mm versus ≥27.35 mm, with an estimated survival of 57.69 months versus 46.34 months (P = .001). CONCLUSIONS: This study does not show a higher rate of postoperative complications in obese patients. There is a significantly lower long-term survival in patients with AAT/height ≥27.35 mm and BMI ≥ 30.45. BMI is a valid estimate of obesity and is predictive of survival.

Comparison of perioperative outcomes in obese and non-obese patients subjected to open lumbar spine surgery.

OBJECTIVE: Obesity is a global epidemic affecting developing countries. The relationship between obesity and perioperative outcomes during elective lumbar spine surgery remains controversial, especially in those without morbid disease. MATERIALS AND METHODS: We retrospectively revised the medical records of patients with lumbar spine degeneration subjected to elective surgery. The data retrieved included demographic and clinical characteristics, body mass index (BMI), obesity status (BMI ≥ 30), surgical interventions, estimated blood loss (EBL), operative time, length of stay (LOS), and post-operative complications. Perioperative outcomes were compared between Grade I-II obese and non-obese individuals. RESULTS: We enrolled 53 patients, 18 with Grade I-II obesity. Their median age was 51, with no differences in gender, comorbidities, laboratory parameters, and surgical procedures received between groups. No clinically relevant differences were found between grade I-II obese and non-obese participants in EBL (300 mL vs. 250 mL, p = 0.069), operative time (3.2 h vs. 3.0 h, p = 0.037), and LOS (6 days vs. 5 days, p = 0.3). Furthermore, BMI was not associated with the incidence of significant bleeding and long stay but showed a modest correlation with operative time. CONCLUSION: Grade I-II obesity does not increase surgical complexity nor perioperative complications during open lumbar spine surgery.

OBJETIVO: La obesidad es una epidemia mundial que afecta a países subdesarrollados. Su relación con los resultados de la cirugía de columna lumbar electiva sigue siendo controvertida, especialmente en obesos sin enfermedad mórbida. MÉTODOS: Se revisaron los expedientes de pacientes con degeneración de la columna lumbar sometidos a cirugía. Los datos recuperados incluyeron características demográficas y clínicas, índice de masa corporal (IMC), estado de obesidad (IMC > 30), intervenciones quirúrgicas, sangrado estimado, tiempo operatorio, tiempo de estancia y complicaciones. Los resultados se compararon entre individuos obesos grado I-II y controles. RESULTADOS: Se incluyeron 53 pacientes, 18 con obesidad de grado I-II. La edad media fue de 51 años, sin diferencias en el sexo, las comorbilidades, los parámetros de laboratorio y los procedimientos quirúrgicos recibidos entre grupos. No se encontraron diferencias relevantes entre los participantes obesos y los no obesos en sangrado (300 vs. 250 mL, p = 0.069), tiempo operatorio (3.2 vs. 3.0 horas, p = 0.037) y estancia (6 vs. 5 días, p = 0.3). El IMC no se asoció con hemorragia y larga estancia, pero mostró una correlación modesta con el tiempo operatorio. CONCLUSIONES: La obesidad grado I-II no predispone a complicaciones durante la cirugía de columna lumbar.

Prevalence of obesity in Spain and its autonomous communities, 1987-2020.

INTRODUCTION AND OBJECTIVES: Obesity is a public health concern with a strong impact on the health of the population. The aim of this study was to analyze the trend in the prevalence of obesity and to identify changes in this trend in Spain and its 17 autonomous communities (AC) among the population aged ≥ 15 years from 1987 to 2020. METHODS: A trend analysis of the prevalence of obesity was conducted with data extracted from the complete historical series of the Spanish National Health Survey and the European Health Survey in Spain using joinpoint regression models. For each period identified in the trend analysis, we estimated the annual percentage change (APC) and its 95% confidence interval (95%CI). The results are presented for crude and standardized prevalences by the direct method accompanied by 95%CI, sex ratios, and relative changes in prevalences between periods. RESULTS: The prevalence of obesity increased from 7.3% (95%CI, 7.0-7.7) in 1987 to 15.7% (95%CI, 15.1-16.3) in 2020. In men, the prevalence increased until 2009 (APC,4.3; [95%CI, 3.8-5.0]) and then stabilized. In women, the prevalence increased until 2001 (APC,4.2; [95%CI, 2.7-8.8]) and subsequently also stabilized. The prevalence of obesity and its trend varied between AC, with three different patterns being observed with standardized prevalences: AC with a continuous increase, AC with an increase and subsequent stabilization, and AC with an increase and subsequent decrease. CONCLUSIONS: The prevalence of obesity has increased in Spain since 1987, although in the last decade it has remained stable at values above 15%. However, in the group aged 15 to 24 years, the prevalence of obesity showed an increasing trend throughout the study period.
