Are very thin patients at a higher risk of complications when submitted to percutaneous nephrolithotomy?

ABSTRACT Purpose: To assess the impact of thinness on the outcome of the percutaneous nephrolithotomy (PCNL). Materials and Methods: A matched case-control study was performed using a prospectively collected database of all patients who underwent PCNL between June 2011 and October 2021. The patients were stratified into two groups according to their phenotypic characteristics, arbitrarily defined according to their body mass index (BMI): <20 kg/m2 (Group 1, very thin patients, G<20) and ≥25 kg/m2 (Group 2, non-thin patients, G≥25). Patients were randomly matched based on Guy's Stone Score (GSS) according to case complexity at a ratio of 1:3. Results: A total of 204 patients were enrolled in this study: 51 patients (G<20) and 153 controls (G≥25). Complications occurred in 15.2% of the patients, with 5.4% of these complications classified as major complications (Clavien grade ≥ 3). According to complications there were no significant differences between the groups. The overall complication rates were 17.6% in the G<20 and 14.4% in the G≥25 (p = 0.653). The major complication rates were 3.9% in the G<20 and 5.8% in the G≥25 (p=0.429). No differences in transfusion or urinary fistula rates were found. Conclusions: In this study, very thin patients were not at a higher risk of complications when submitted to PCNL than in those with a BMI of ≥25 kg/m2. Apparently, this technique can be used in these patients, just as it is used in any other type of patient, independently of their BMI.

Correlación y concordancia entre índice de masa corporal y perímetro abdominal para la detección de sobrepeso u obesidad en la población peruana, 2022 / Correlation and agreement between body mass index and abdominal perimeter for the detection of overweight or obesity in the Peruvian population, 2022

RESUMEN Introducción: el índice de masa corporal y el perímetro abdominal son medidas antropométricas que podrían ser concordantes en la población peruana para el cribado de sobrepeso u obesidad. Objetivo: analizar la correlación y concordancia entre las pruebas de índice de masa corporal y perímetro abdominal para la detección de sobrepeso u obesidad en adultos peruanos. Metodología: estudio observacional, analítico y transversal basado en datos de la encuesta nacional demográfica de salud familiar. La población fue de 28960 adultos. Las variables fueron: índice de masa corporal y perímetro abdominal. Se utilizó la prueba V de Cramer, t de student, correlación de Spearman y kappa de Cohen. Resultados: hubo una asociación fuerte entre índice de masa corporal y perímetro abdominal en mujeres (V=0,701), moderada en hombres (V=0,632). En la prueba kappa de Cohen, ambas variables concordaron sustancialmente en mujeres (kappa=0,677) y moderadamente en hombres (kappa=0,580). Mediante el Odds Ratio, las mujeres con índice de masa corporal elevado tuvieron una probabilidad 97,22 veces mayor de perímetro abdominal elevado, mientras que en hombres con índice de masa corporal elevado fue 110,76 veces mayor. La correlación de Spearman fue muy alta y positiva en ambos sexos Conclusiones: el perímetro abdominal y el índice de masa corporal están asociados y correlacionados significativamente en adultos peruanos, presentaron una concordancia sustancial en mujeres y moderada en hombres. Se sugiere priorizar el uso del perímetro abdominal, debido a que distingue sobrepeso u obesidad según sexo, optimizándolo mediante la determinación de un punto de corte ajustado a la población peruana.

ABSTRACT Introduction: body mass index and abdominal perimeter are anthropometric measurements that could be concordant in the Peruvian population for screening for overweight or obesity. Objective: to analyze the correlation and agreement between body mass index and abdominal circumference tests for the detection of overweight or obesity in Peruvian adults. Methodology: observational, analytical and cross-sectional study based on data from the national demographic family health survey. The population was 28,960 adults. The variables were: body mass index and abdominal perimeter. Cramer's V test, student's t, Spearman's correlation and Cohen's kappa were used. Results: there was a strong association between body mass index and abdominal perimeter in women (V=0.701), moderate in men (V=0.632). In Cohen's kappa test, both variables agreed substantially in women (kappa=0.677) and moderately in men (kappa=0.580). Using the Odds Ratio, women with a high body mass index had a 97.22 times greater probability of having a high abdominal circumference, while in men with a high body mass index it was 110.76 times greater. The Spearman correlation was very high and positive in both sexes. Conclusions: abdominal circumference and body mass index are significantly associated and correlated in Peruvian adults; they presented substantial agreement in women and moderate agreement in men. It is suggested to prioritize the use of the abdominal perimeter, because it distinguishes overweight or obesity according to sex, optimizing it by determining a cut-off point adjusted to the Peruvian population.

Correlación del índice de masa corporal y grosor de tejido adiposo en glúteos / Correlation of body mass index and adipose tissue thickness in glutes

Introducción: Con el aumento de la prevalencia de obesidad, se esperaría un mayor espesor glúteo, lo que sería un factor importante en futuras intervenciones en región glútea con fines de optimizar mejores resultados estéticos. Objetivo: Correlacionar el índice de masa corporal y el grosor de tejido adiposo en glúteos en voluntarias que acudieron al Servicio de Cirugía Plástica y Reconstructiva del Hospital Dr. Miguel Pérez Carreño entre enero a marzo, 2023. Métodos: El estudio fue prospectivo, descriptivo y de corte transversal. Se utilizó un sonógrafo Sono Eye 1 para realizar las medidas del glúteo. Mediante una báscula, se midió peso y talla, para posteriormente calcular el IMC, fueron 29 voluntarias de sexo femenino entre 18 a 60 años, sin antecedentes quirúrgicos estéticos previos. Las correlaciones fueron evaluadas con el coeficiente de correlación de Pearson. Se consideró un valor significativo si p < 0,05. Los datos fueron tabulados con STATA 17. Resultados: La edad promedio fue 39 ± 12 años. La mayoría con preobesidad (55,2 %). No hubo diferencias estadísticas en grosor de tejido adiposo, de musculo y espesor de glúteo de acuerdo a la lateralidad; de acuerdo al coeficiente de correlación de Pearson, el IMC no hubo asociación con las medidas combinadas del glúteo izquierdo y derecho del grosor de tejido graso (r = 0,137), grosor muscular (r = 0,115) y espesor glúteo (r = 0,193). Conclusión: Los cambios de las medidas antropométricas de acuerdo al índice de masa corporal, no presentaron correlación estadística con el espesor glúteo. (AU)

Introduction: With the increasing prevalence of obesity, a greater gluteal thickness would be expected, which would be an important factor in future interventions in the gluteal region aimed at optimizing better aesthetic outcomes. Objective: To correlate the body mass index (BMI) and the thickness of adipose tissue in the buttocks of volunteers who attended the Plastic and Reconstructive Surgery Service at Dr. Miguel Pérez Carreño Hospital from January to March, 2023. Methods: The study was prospective, descriptive, and cross-sectional. A Sono Eye 1 sonograph was used to measure the gluteal thickness. Using a scale, weight and height were measured to subsequently calculate the BMI; there were 29 female volunteers aged between 18 and 60 years, without previous aesthetic surgical history. Correlations were assessed using Pearson's correlation coefficient. A significant value was considered if p < 0.05. Data were tabulated using STATA 17. Results: The average age was 39 ± 12 years. The majority had pre-obesity (55,2%). There were no statistical differences in adipose tissue thickness, muscle thickness, and gluteal thickness according to laterality; according to Pearson's correlation coefficient, BMI was not associated with combined measurements of left and right buttock adipose tissue thickness (r = 0,137), muscle thickness (r = 0,115), and gluteal thickness (r = 0,193). Conclusion: Changes in anthropometric measurements according to body mass index did not show a statistical correlation with gluteal thickness. (AU)

Prevalence of Hamstring Tightness in Nursing Students Using 90-90 SLR Test: A Cross-Sectional Study

Background: Flexibility is a range of movement available at a joint. Tightness of muscle is caused by a decline in the ability of muscle to disfigure. Hamstring tightness can lead to low back pain, bad posture, imbalances of muscles and knee pain. According to previously performed studies, prolonged sitting can be a factor that leads to hamstring tightness; therefore, we selected nursing students as a participant in the study who have a daily sitting time of 6-8 hours. Hence objective of the study is to find out the prevalence of hamstring tightness among nursing students. Aim: The study’s aim was to find out if Nursing Students have hamstring tightness due to Prolonged Sitting using a 90-90 SLR test. Study design: Observational study. Methodology: In this cross-sectional study, 145 participants were included by verifying inclusion and exclusion criteria. Consent was taken before evaluation. Hamstring tightness was measured by a 90-90 SLR test. After that, height and weight were measured, and BMI was calculated. After evaluating all participants, prevalence was calculated. Then, it was compared with BMI. Result: 20.68 percent of participants had hamstring tightness. Conclusion: The result indicates that the prevalence of hamstring tightness is low in nursing students.

The quality of the settings was checked by worm plots. Results: The first Brazilian growth charts for weight-for-age, height-for-age, and BMI-for-age stratified by gender were constructed for WBS patients aged 2 to 18 years. Conclusion: The growth charts developed in this study can help to guide family members and to improve the health care offered by health professionals.

Predicción de la valoración del recién nacido según el estado nutricional materno: modelo basado en árboles de decisión / Prediction of newborn assessment according to maternal nutritional status: a model based on decision trees

Objetivo: Determinar si es posible predecir la valoración del recién nacido según el estado nutricional materno a través de un modelo de árbol de decisión. Métodos: Estudio analítico transversal. Se revisaron 326 historias clínicas de gestantes de un hospital público peruano, 2021. Se valoró el recién nacido mediante el puntaje APGAR, edad gestacional al nacer, peso al nacer, peso y talla para la edad gestacional. El estado nutricional materno incluyó el índice de masa corporal pregestacional y la ganancia de peso gestacional. La predicción se realizó mediante un modelo de aprendizaje automático supervisado denominado "árbol de decisión". Resultados: No fue posible predecir mediante el estado nutricional materno, el puntaje APGAR al minuto y la talla para la edad gestacional. La probabilidad de tener edad gestacional a término al nacer es de 97,2 % cuando la ganancia de peso gestacional es > 5,4 Kg (p = 0,007). Las probabilidades más altas de peso adecuado al nacer fueron con ganancia de peso gestacional entre 4,5 Kg (p < 0,001) y 17 Kg (p < 0,001) y con índice de masa corporal pregestacional ≤ 36,523 Kg/m2 (p = 0,004). Finalmente, la mayor probabilidad de peso adecuado para la edad gestacional es cuando la ganancia de peso gestacional es ≤ 11,8 Kg (p < 0,001) y con un índice de masa corporal pregestacional ≤ 36,523 Kg/m2 (p = 0,005). Conclusiones: Es posible predecir la valoración del recién nacido a partir del estado nutricional materno mediante un aprendizaje automático(AU)

Objective: To determine whether it is possible to predict the assessment of the newborn according to maternal nutritional status through a decision tree model. Methods: Cross-sectional analytical study. A total of 326 medical records of pregnant women from a Peruvian public hospital were reviewed, in 2021. The newborn was assessed using the APGAR score, gestational age at birth, birth weight, weight and height for gestational age. Maternal nutritional status included pregestational body mass index and gestational weight gain. The prediction was made using a supervised machine learning model called a "decision tree." Results: The APGAR score at one minute and height for gestational age were not possible to predict by maternal nutritional status. The probability of having full-term gestational age at birth is 97.2% when gestational weight gain is > 5.4 kg (p = 0.007). The highest probabilities of adequate birth weight were with gestational weight gain between 4.5 kg (p < 0.001) and 17 kg (p < 0.001) and with pregestational body mass index ≤ 36.523 kg/m2 (p = 0.004). Finally, the highest probability of adequate weight for gestational age is when gestational weight gain is < 11.8 Kg (p < 0.001) and with a pregestational body mass index ≤ 36.523 Kg/m2 (p = 0.005). Conclusions: It is possible to predict the assessment of the newborn based on the mother's nutritional status using machine learning(AU)

Resumen Objetivo: Determinar la relación de la Imagen Corporal Positiva con la insatisfacción corporal, la actividad física, la interiorización de los ideales de belleza que presentan los medios de comunicación y el índice de masa corporal en adolescentes de la Costa Caribe Colombiana. Método: Se realizó un estudio cuantitativo de corte transversal, donde la muestra estuvo conformada por 300 estudiantes de la ciudad de Barranquilla jóvenes entre los 13 y los 19 años, 151 eran mujeres y 149 eran hombres. Resultados: Una mayor imagen corporal positiva se asoció con mayor cantidad de horas de actividad física, menor índice de masa muscular, menor insatisfacción corporal y menor interiorización de los ideales de belleza que presentan los medios. Las mujeres mostraron menor imagen corporal positiva que los hombres. La asociación de estas variables ha permitido conformar perfiles de riesgo de trastorno de la conducta alimentaria en mujeres. La imagen corporal positiva resultó un factor de protección significativo de la insatisfacción corporal tanto en hombres como en mujeres. Conclusión: Este estudio ha permitido ahondar el conocimiento de la imagen corporal positiva en una población de escasa representación en las investigaciones internacionales como son los adolescentes en Latinoamérica.

Abstract Objective: To determinate the relationship between positive body image and body dissatisfaction, physical activity, internalization of beauty ideals presented by media and the body mass index in adolescents from the Colombian Caribbean Coast. Method: A quantitative cross-sectional study was carried out. The sample consisted of 300 students from the city of Barranquilla between 13 and 19 years of age, 151 were female and 149 were male. Results: Higher positive body image was associated with more hours of physical activity, lower body mass index, lower body dissatisfaction and lower internalization of beauty ideals. Females showed lower positive body image than males, The association of these variables allowed risk profiles for eating disorders in women. Positive body image was a significant protective factor for body dissatisfaction in both men and women Conclusion: This study has allowed us to deepen our knowledge of positive body image in a population that is underrepresented in international research, such as adolescents in Latin America.

Conclusión: El IMC se asoció significativamente con las cifras de presión arterial sistólica y diastólica en adolescentes de un área urbana de México.

ABSTRACT Introduction: The changes brought about by the COVID-19 pandemic in adolescent activities have affected recreational aspects due to limited contact to prevent virus spread. This has contributed to increased indicators of overweight and obesity and could impact blood pressure levels. Objective: To determine the degree of association between Body Mass Index (BMI) and systemic blood pressure in adolescents. Methods: Systemic blood pressure was measured using continuous ambulatory blood pressure monitoring over 24 hours (ABPM). The sample consisted of 42 high school students with similar urban geographic characteristics in Mexico. All participants underwent anthropometric evaluation to identify notable group characteristics. The correlation was assessed using Spearman's Rho test. Results: Of the 42 participants included, 28.5% showed obesity, 21.45% were overweight, and no patient had hypertension. However, 23.8% showed prehypertension. A significant correlation was evidenced between BMI and both systolic and diastolic blood pressure values, at 0.390 and 0.382, respectively (p-value: 0.013 and 0.015, respectively). Conclusion: BMI was significantly associated with systolic and diastolic blood pressure levels in adolescents from an urban area in Mexico.

Understanding motivators and barriers for yoga practice in obese and non-obese individuals

Background: Yoga is a comprehensive lifestyle intervention which has been used for weight management by overweight and obese. Yoga is also used as therapy for various other ailments by both obese and non-obese individuals. However, the motivators and barriers of yoga in obese persons compared to non-obese has not been reported. Methods: The present cross-sectional comparative control trial included 200 participants of both sexes aged between 13 and 80 years. Of these, 102 were obese and 98 were non-obese. Data were analyzed using Chi-square test. Results: The most common motivators for yoga were: reducing symptoms of illness (35% for obese versus 21.73% for non-obese), pain relief, (21% for obese versus 10.86% for non-obese) and lifestyle changes (9% for obese versus 10.86% for non-obese). The most common barriers for yoga were: no time (29.54% for obese versus 42.25% for non-obese), physical incapability of practicing yoga (18.18% for obese versus 16.9% for non-obese) and tiredness (15.9%) for obese and no interest/motivation (15.49%) for non-obese. Conclusions: The motivators to yoga for obese are comparable to non-obese with obese use yoga more frequently for 搑educing symptoms of illness�. Also, the barriers to yoga are comparable to obese with normal weight for 搉o time�.

Study of the response of PCOS patients to clomiphene citrate based on hormonal Parameters and body mass index

Background: Our study aimed to evaluate the response of polycystic ovarian syndrome patients to clomiphene citrate based on hormonal parameters and body mass index.Methods: It is a prospective observational study that was carried out on 48 women with PCOS-related infertility. They were treated with an incremental dose of clomiphene citrate starting with 50 mg/day to a maximum of 100 mg. The response was recorded as either the presence or absence of ovulation. Hormonal parameters such as serum FSH, LH, testosterone, fasting insulin, DHEA, prolactin, and body mass index (BMI) were evaluated. The correlation of each of these parameters in predicting non-responsiveness (failure to ovulate with 100 mg clomiphene) was calculated.Results: Among 48 PCOS patients who were enrolled in the study, 14 patients responded to CC 50 mg, 26 patients responded to CC 100 mg and 8 patients were CC non-responders. We concluded that serum LH, fasting insulin, and BMI were significant predictors of response to ovulation with CC in PCOS patients.Conclusions: In our study, we concluded that among the hormonal and biochemical parameters we studied serum LH, fasting insulin, and BMI are significant predictors of response of ovulation with CC in women with PCOS-related infertility. This may help physicians to counsel and select the proper infertility treatment for women with PCOS experiencing infertility so that it should be less time-consuming and cost-effective.

Métodos: Estudio analítico, retrospectivo. Se incluyeron gestantes a término, mayores de 18 años, con fetos únicos vivos, historia clínica legible y tarjeta de atención prenatal con primer y último control, atendidas en un hospital público del Perú, entre enero ­ junio 2022. Se excluyeron pacientes con problemas mentales, y/o con fetos con malformaciones. Las variables medidas fueron: características sociodemográficas, obstétricas, ganancia de peso gestacional y complicaciones maternas. El excedente de peso gestacional se definió con el índice de masa corporal pregestacional, diferencia de peso entre primer y último control prenatal, y las pautas del Instituto de Medicina. Se hizo un análisis descriptivo y para reconocer la relación entre la ganancia de peso gestacional y los resultados maternos, se utilizó X2. El Comité Institucional de Ética en Investigación de la Universidad Nacional de San Agustín otorgó la aprobación del estudio. Resultados: Se incluyeron 1021 gestantes en el estudio. De estas, el 49,0 % tuvo excesivo peso gestacional. 43,0 % de pacientes con peso excesivo tuvo complicaciones maternas. Se observó anemia en 7,9 % con ganancia de peso adecuada y en 4 % con excesiva ganancia de peso (p = 0,009), 0,2 % y 1,8 % de diabetes, respectivamente, (p = 0,009). Las otras complicaciones evaluadas no mostraron diferencias significativas entre los grupos. Conclusión: Las pacientes con excesiva ganancia de peso en la gestación tuvieron mayor probabilidad de padecer diabetes gestacional(AU)

Objective: TTo determine the demographic and clinical characteristics, of pregnant women with excessive gestational weight gain. And determine their relationship with maternal complications. Methods: Analytical, retrospective study. Full-term pregnant women, older than 18 years and with single live fetuses, with legible clinical history and prenatal care card with first and last check-up, treated at a public hospital in Peru between January - June 2022, were included. Patients with mental problems and those with fetuses with malformations, were excluded. The variables measured were: sociodemographic characteristics, obstetric, gestational weight gain, and maternal complications. Excess gestational weight was defined using pre-pregnancy body mass index, difference in weight between the first and last prenatal check-up, and Institute of Medicine guidelines.

The National University of San Agustín Institutional Research Ethics Committee granted approval of the study. Results: We included 1021 pregnant women in the study. Of these, 49.0% had excessive gestational weight. 43.0% of overweight patients had maternal complications. A relationship was found between excessive weight gain in pregnancy and gestational diabetes. Conclusions: Patients with excessive weight gain in pregnancy were more likely to have gestational diabetes(AU)

The Relationship of Anatomical Localizations of Hiatal Clamp and Oesophagogastric Junction with Body Mass Index / Relación entre las Localizaciones Anatómicas de la Pinza Hiatal y la Unión Esofagogástrica con el Índice de Masa Corporal

SUMMARY: In our study, we aimed to reveal the relationship between the anatomical localizations measured and the Body Mass Index (BMI) in patients scheduled for upper gastrointestinal endoscopy. In this study, anatomical localizations of the hiatal clamp and oesophagogastric junction in 189 female and 137 male patients who applied to the hospital with different gastrointestinal system complaints and underwent esophagogastroduodenoscopy (EGD) were investigated depending on BMI. In addition, the data were compared with the patients' complaints before EGD and the diagnoses they received after EGD. SPSS Statistics 22 (IBM Corp. Turkey) program was used for statistical analysis and p0.05). On the other hand, it was determined that the hiatal clamp distance and the distance of the oesophagogastric junction increased as the height and weight increased (p38. As a result of the study, it can be said that BMI values, hiatal clamp distance and oesophagogastric junction localizations may change in relation to height and weight.

En este estudio, buscamos revelar la relación entre las localizaciones anatómicas y el Índice de Masa Corporal (IMC) en pacientes programados para endoscopía digestiva alta. Se investigaron las localizaciones anatómicas de la pinza hiatal y la unión esofagogástrica en 189 mujeres y 137 hombres que acudieron al hospital con diferentes problemas del sistema gastrointestinal los cuales fueron sometetidos a una esofagogastro- duodenoscopia (EGD) dependiendo del IMC. Además, los datos se compararon con las quejas de los pacientes antes de la EGD y los diagnósticos que recibieron después de la EGD. Se utilizó el programa SPSS Statistics 22 (IBM Corp. Turquía) para el análisis estadístico y el valor de p0,05). Por otro lado, se determinó que la distancia de la pinza hiatal y la unión esofagogástrica aumentaba con la altura y el peso corporal (p38. Como resultado del estudio, se puede decir que los valores de IMC, la distancia de pinzamiento hiatal y las localizaciones de la unión esofagogástrica pueden cambiar en relación con la altura y el peso.

Follow up study of the association between bedroom light at night exposure and body mass index in children / 中国学校卫生

Objective@#To explore the association between bedroom light at night (LAN) exposure and body mass index (BMI) in children at 1 year follow up, so as to provide new strategies for obesity prevention.@*Methods@#From December 2021 to May 2022, cluster random sampling was conducted, involving 648 children from two primary schools in Tianchang, Chuzhou City, Anhui Province, China, to assess bedroom LAN exposure of children during sleep. A questionnaire survey and physical examination were carried out in May 2022. Multivariate linear regression was performed to analyze the correlation between bedroom LAN exposure and BMI variable quantity at 1 year follow up (May, 2023).@*Results@#The median intensity of bedroom LAN exposure during the sleep episode was [1.11(0.35,3.24)lx] in children. The proportion of the sample exposed to an average light intensity of ≥3 lx was 27.5%, while 19.0% was exposed to a LAN intensity of ≥5 lx during the sleep episode. In the multivariable linear regression, after adjusting for covariates, including sex, baseline age, sleep duration, family monthly income, and maternal education level, exposure to a 1 h-average post bedtime LAN intensity of ≥3 lx ( β=0.25, 95%CI =0.05-0.44) and LAN≥5 lx ( β=0.34, 95% CI = 0.12-0.55) was associated with a gain of 0.25 and 0.34 kg/m 2, respectively, in the children s BMI at the 1 year follow up ( P < 0.05).@*Conclusions@#A positive correlation was found between bedroom LAN exposure and BMI variable quantity at 1 year follow up in children. Thus, reduced bedroom LAN exposure might be useful for interventions aimed at obesity prevention.

Disease Burden of Esophageal Cancer Attributable to High BMI and Death Prediction in China and the United States, 1990-2019 / 肿瘤防治研究

Objective To analyze trends in the disease burden of esophageal cancer attributable to high body mass index (BMI) in the Chinese and United States populations from 1990 to 2019 and predict deaths over the next 10 years. Methods This study used Global Burden of Disease 2019 data to obtain mortality and disability-adjusted life-year (DALY) data by year, gender, and age for the disease burden of esophageal cancer attributable to high BMI in China and the United States from 1990 to 2019. Joinpoint regression analysis was conducted to analyze long-term trends. Bayesian age–period–cohort analysis was used to predict age-standardized mortality attributable to esophageal cancer in 2020–2030. Results From 1990 to 2019, the age-standardized mortality rate for esophageal cancer attributable to high BMI in China increased from 1.44/105 to 1.80/105 and the age-standardized DALY rate increased from 34.17/105 to 40.79/105. From the perspective of gender, the number of deaths, DALYs, and the corresponding age-standardized rate of males in China and the United States increased from 1990 to 2019. The age-standardized mortality and DALY rates of Chinese women showed a downward trend, decreasing by 21.36/105 and 29.71/105, respectively. Joinpoint analysis results revealed that the average annual percentage changes (AAPCs) in mortality attributable to esophageal cancer in the total population and men in China from 1990 to 2019 increased by 0.78% (95%CI: 0.71-0.84) and 1.52% (95%CI: 1.44-1.60), respectively, and that in females decreased by 0.88% (95%CI: −0.96-−0.80). AAPC in women in the United States rose at a slow rate of 0.07% (95%CI: 0.02-0.09). The burden of esophageal cancer deaths attributable to high BMI is predicted to continue to rise in China and the United States in 2020–2030. Conclusion The disease burden of esophageal cancer attributable to high BMI significantly increased in China from 1990 to 2019. The disease burden of esophageal cancer caused by high BMI in China is expected to increase from 2020 to 2030.

Prevalence of central obesity among the elderly with different body mass indexes in Xuhui District， Shanghai / 上海预防医学

ObjectiveTo investigate the prevalence and influencing factors of overweight， obesity and central obesity among elderly residents in Xuhui District， and to analyze the epidemiological status of central obesity in elderly people with different body mass indexes. MethodsThe third round of health status and health service utilization monitoring data in Xuhui District was used. The information collected from questionnaire survey and physical examination were analyzed. SPSS 20.0 software was used for χ2 test， trend χ2 test and multinominal logistic regression analysis. Results5 096 survey subjects were included. The prevalence of overweight， general obesity， and central obesity in the residents aged 60 and above in Xuhui District were 34.3%， 6.5%， and 29.2%， respectively. There was gender difference in the rates of overweight， obesity， and central obesity among the residents. The overweight and central obesity rates in males were higher than those in females， while the obesity rate was lower than that in females （P<0.05）. Multinominal logistic regression analysis showed that in comparison with the normal weight non-central obesity group drinking only at party （OR=1.729， 95%CI： 1.184‒2.525）， and hypertension （OR=1.637， 95%CI： 1.305‒2.053）， were highly associated with normal weight with central obesity. Aged 60‒ years （OR=1.589， 95%CI： 1.190‒2.120）， aged 70‒ years （OR=1.763， 95%CI： 1.327‒2.342）， male （OR=1.379， 95%CI： 1.134‒1.676）， hypertension （OR=2.231， 95%CI： 1.878‒2.649）， former smokers （OR=1.437， 95%CI： 1.027‒2.011）， drinking at party only （OR=1.491， 95%CI： 1.107‒2.006）， and drinking ≥3 times per week （OR=1.611， 95%CI： 1.116‒2.325）， were highly associated with overweight combined with central obesity. Aged 60‒ years （OR=3.817， 95%CI： 2.251‒6.474）， aged 70‒ years （OR=3.084， 95%CI： 1.838‒5.175）， hypertension （OR=3.683， 95%CI： 2.753‒4.929）， diabetes （OR=2.085， 95%CI： 1.511‒2.878）， former smokers （OR=1.835， 95%CI： 1.043‒3.226）， were highly associated with compound obesity. Central obesity was found in the elderly residents with different BMI categories， and the rate of central obesity increased with the increase of BMI grade. ConclusionThe prevalence of overweight， obesity and central obesity among the elderly aged 60 years and above in Xuhui District is not optimistic. Attention should be paid to the elderly under 80 years old who are with hypertension and/or diabetes， alcohol consumption， low educational level and not doing physical exercise. Especially for the central obesity population with normal BMI， measures should be taken to prevent and intervene the occurrence of obesity and related diseases.

Disease burden of dementia attributed to high BMI in 1990–2019 / 公共卫生与预防医学

Objective To understand the changing trend of dementia disease burden attributed to high BMI in China from 1990-2019, and to provide a basis for the development of dementia prevention and control strategies. Methods Using data from the Global Burden of Disease Study 2019(GBD2019)，the changes in disease burden were analyzed using indicators such as deaths, disability adjusted life years (DALYs), years lived with disability (YLDs), years of life lost (YLLs) and their standardized rates. The differences between sexes and age groups were compared. Joinpoint regression model was used to analyze the trend of changes in the disease burden of dementia attributable to high BMI in China. Results From 1990 to 2019, the burden of dementia disease attributed to high BMI continued to increase, with 20,300 more deaths, 404,200 more DALYs, and more than a four-fold increase in both mortality and DALYs rates. The overall burden of disease was greater for women than for men, but the rate of increase in the burden of disease was higher for men than for women. The disease burden in the age group of 80 and over was significantly higher than in other age groups. Conclusion Attention should be paid to people with high BMI, especially for the prevention and control of dementia risk in older age groups with high BMI. Active countermeasures should be taken to control the occurrence of dementia.

Characteristics of resting energy expenditure and evaluation of prediction formulas in young men with different body mass indexes / 北京大学学报(医学版)

Objective:To compare the resting energy expenditure(REE)characteristics among young men with different body mass indexes(BMI).Methods:Thirty young men[average age was(26.93± 4.16)years]were enrolled in this study.They underwent resting metabolism tests in the Department of Sports Medicine of Peking University Third Hospital from December 2017 to June 2021.The resting meta-bolic rate(RMR)was measured by indirect calorimetry,the body composition was measured by bioresis-tance antibody component analyzer.The REE characteristics were analyzed,and 11 predictive equations were used to estimate RMR and compared with the measured value.The differences were analyzed by paired t-test and intra-class correlation coefficient(ICC).Results:The RMR of the overall 30 young men was(1 960.17±463.11)kcal/d(1 kcal=4.186 8 kJ).Including(1 744.33±249.62)kcal/d in those with normal BMI,which was significantly lower than that in those who were overweight or obese[(2 104.06±520.32)kcal/d,P＜0.01],but the weight-corrected RMR in those with normal BMI was significantly higher than that in those who were overweight or obese[(24.02±2.61)kcal/(kg·d)vs.(19.98±4.38)kcal/(kg·d),P＜0.01].The RMR was significantly and positively correlated with body weight,adiposity,lean body mass,body surface area,and extracellular fluid in the subjects with diffe-rent BMI(all P＜0.05).The predicted values of the 11 prediction equations were not in good agreement with the measured values(all ICC＜0.75),with relatively high agreement between the pre-dicted and measured values of the World Health Organization(WHO)equation in overweight obese young men(ICC=0.547,P＜0.01).Conclusion:There were significant differences in RMR among young men with different BMI,and the RMR after weight correction should be considered for those who were overweight or obese.The consistency between the predicted values of different prediction equations and the actual measured values of RMR was relatively poor,and it is recommended to accurately measure RMR by indirect calorimetry.For overweight or obese young men,the WHO prediction equation can be considered to calculate RMR,but it is necessary to establish an RMR prediction equation applicable to different BMI populations.
