ABSTRACT

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)

ABSTRACT

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)

ABSTRACT

Introduction: Early childhood caries is still very prevalent, mainly in developing countries, and it is related to the quality of life of children due to early tooth loss. Objective: The study objective was to determine the association between dental caries and its clinical consequences on nutritional status in children of the "Vaso de Leche (Glass of Milk)'' social program, in Puno City, Peru, during the year 2020. Materials and Methods: An observational, descriptive-correlational, cross-sectional study; the sample consisted of 740 children between 1 and 5 years old who met the selection criteria; the clinical consequences of untreated dental caries were evaluated using the PUFA index and the prevalence of caries with def-t; the nutritional status was determined by the weight and height of the child according to protocols (NTS No. 357 - MINSA /2017/ DGIESP); the data were analyzed with the SPSS-v25 program, the association between variables was evaluated with the chi-square test, Mann-Whitney U test and Spearman's Rho test, considering significance at a p-value <0.05. Results: No significant relationship was found when dental caries was evaluated with the nutritional condition (p<0.05). However, when the def-t index values were related to the nutritional condition of the children, a significant difference was found (p<0.05). There was no significant difference with the PUFA index (p>0.05). Conclusions: There is no association between early childhood caries and nutritional status in children aged between 3 and 5 years; however, a significant relationship was found between the values of the def-t index and the nutritional status of the children.

ABSTRACT

RESUMEN Introducción: Los cambios realizados por la pandemia de COVID-19 en las actividades de los adolescentes han afectado los aspectos recreativos debido a la limitación de contacto para evitar la propagación del virus. Esto ha contribuido a aumentar los indicadores de sobrepeso y obesidad y podría tener un impacto en las cifras de presión arterial. Objetivo: Determinar el grado de asociación entre el Índice de Masa Corporal (IMC) y la presión arterial sistémica en adolescentes. Métodos: La medición de la presión arterial sistémica se realizó utilizando el monitoreo de presión ambulatoria continua durante 24 horas (MAPA). La muestra consistió en 42 estudiantes de secundaria con características geográficas urbanas similares en México. Todos los participantes fueron evaluados antropométricamente para identificar características notables del grupo. Se evaluó la correlación a través de la prueba Rho de Spearman. Resultados: De los 42 participantes incluidos, el 28,5% mostró obesidad, el 21,45% presentó sobrepeso y ningún paciente tenía hipertensión. Sin embargo, el 23,8% mostró prehipertensión. Se evidenció una correlación significativa del IMC con los valores la presión arterial sistólica y diastólica de 0,390 y 0,382, respectivamente (valor de p: 0,013 y 0,015; respectivamente). 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.

ABSTRACT

Objetivo. Determinar la presencia y dirección de la relación entre alfa-amilasa salival (AAs), edad, sexo e índice de masa corporal (IMC) en adultos jóvenes. Métodos. Este estudio transversal se desarrolló con una muestra de 50 estudiantes de odontología de 19 a 34 años de edad, 58% mujeres y 42% hombres. Se recogieron muestras de saliva entera sin estimular en la mañana (6:30-7:30 a.m.) y en la tarde (4:00-6:00 p.m.). Los valores de AAs se determinaron mediante método cinético y se expresaron como media ± desviación estándar. Se realizaron análisis descriptivo de datos, prueba de chi-cuadrado, prueba de correlación de Pearson y prueba t de muestras pareadas. Resultados. El IMC promedio fue de 23,85 ± 3,30 kg/m2, 66% de los participantes presentó peso normal (IMC ≤ 25 kg/m2). Los niveles de AAs por la tarde (282,74 ± 59,60 U/ml) fueron mayores a los de la mañana (190,84 ± 61,80 U/ml), (t = 16,51, p < 0,0001). Los hombres mostraron niveles de AAs más altos que las mujeres (p < 0,0001). La edad no mostró asociación con los niveles de AAs. Los valores de IMC y AAs presentaron una correlación positiva (AM: r = 0,35, p = 0,0121; PM: r = 0,40, p = 0,0036). Conclusión. El nivel de actividad de AAs se puede utilizar como posible biomarcador para evaluar el IMC en relación con el sexo, especialmente en los adultos jóvenes.


Objective. To determine the presence and direction of the relationship between salivary alpha-amylase (sAA), age, sex, and body mass index (BMI) in young adults. Methods. This cross-sectional study was developed with a sample of 50 dental students from 19 to 34 years of age, 58% women and 42% men. Unstimulated whole saliva samples were collected in the morning (6:30-7:30 a.m.) and in the afternoon (4:00-6:00 p.m.). sAA values were determined by the kinetic method and expressed as mean ± standard deviation. Descriptive data analysis, chi-square test, Pearson correlation test, and paired samples t-test were made. Results. Mean BMI was 23.85 ± 3.30 kg/m2, 66% of the participants presented normal weight (BMI ≤ 25 kg/m2). Levels of sAA in the afternoon (282.74 ± 59.60 U/ml) were higher than those in the morning (190.84 ± 61.80 U/ml), (t = 16.51, p < 0, 0001). Men showed higher levels of sAA than women (p < 0.0001). Age did not show an association with sAA levels. BMI and AAs values presented a positive correlation (AM: r = 0,35, p = 0,0121; PM: r = 0,40, p = 0,0036). Conclusions. AAs activity level can be used as a potential biomarker to assess BMI in relation to sex, especially in young adults.

ABSTRACT

Objetivo: Determinar las características demográficas y clínicas, de embarazadas con ganancia excesiva de peso gestacional y su relación con las complicaciones maternas. 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)

ABSTRACT

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.

ABSTRACT

OBJECTIVES@#To explore the relationship of triglyceride-glucose index (TyG), triglyceride-glucose-body mass index (TyG-BMI), and triglyceride-glucose-waist circumference index (TyG-WC) with blood pressure abnormalities in adolescents, providing theoretical basis for the prevention and control of hypertension in adolescents.@*METHODS@#A stratified cluster sampling method was used to select 1 572 adolescents aged 12 to 18 years in Yinchuan City for questionnaire surveys, physical measurements, and laboratory tests. Logistic regression analysis and restricted cubic spline analysis were employed to examine the relationship of TyG, TyG-BMI, and TyG-WC with blood pressure abnormalities in adolescents.@*RESULTS@#Multivariable logistic regression analysis revealed that after adjusting for confounding factors, the groups with the highest quartile of TyG, TyG-BMI, and TyG-WC had 1.48 times (95%CI: 1.07-2.04), 3.71 times (95%CI: 2.67-5.15), and 4.07 times (95%CI: 2.89-5.73) higher risks of blood pressure abnormalities compared to the groups with the lowest quartile, respectively. Moreover, as the levels of TyG, TyG-BMI, and TyG-WC increased, the risk of blood pressure abnormalities gradually increased (P<0.05). A non-linear dose-response relationship was observed between TyG-BMI and the risk of blood pressure abnormalities (P overall trend<0.001, P non-linearity=0.002). Linear dose-response relationships were found between TyG and the risk of blood pressure abnormalities (P overall trend<0.001, P non-linearit =0.232), and between TyG-WC and the risk of blood pressure abnormalities (P overall trend<0.001, P non-linearity=0.224).@*CONCLUSIONS@#Higher levels of TyG and its derivatives are associated with an increased risk of blood pressure abnormalities in adolescents, with linear or non-linear dose-response relationships.

ABSTRACT

Objective:To investigate the current situation and related factors of children's growth and development in drinking-water-borne endemic fluorosis areas after water improvement, and provide a basis for improving the control strategies.Methods:The stratified random sampling method was used to select children aged 7 to 13 in villages with different years of water improvement in Xi'an from November 2019 to June 2020. The height and weight of children were measured, and body mass index (BMI) was calculated. The height development level of children was graded according to the "Standard for Height Level Classification among Children and Adolescents Aged 7 - 18 Years" (WS/T 612-2018), and the physical development (BMI) level of children was determined according to the "Comprehensive Evaluation of Development Level for Children and Adolescents" (GB/T 31178-2014). At the same time, according to the standard of "Diagnosis of Dental Fluorosis" (WS/T 208-2011), the diagnosis of dental fluorosis in children was performed. The serum fluoride level was determined by ion selective electrode method, and the levels of other chemical elements (calcium, iron, magnesium, copper, zinc, iodine, selenium, lead, arsenic, cadmium, chromium, mercury, nickel) in blood were determined by inductively coupled plasma mass spectrometry.Results:A total of 469 children were included in the investigation. After water improvement, 67.38% (316/469) of the children in the disease area were at the moderate level of height development, 7.89% (37/469) were at the medium to upper and upper levels, and 24.73% (116/469) were at the medium to lower and lower levels. The BMI of the children in the emaciation group was 8.53% (40/469), while it was 10.87% (51/469) in the overweight group and 8.74% (41/469) in the obesity group. There was statistically significant difference in the distribution of height development level of children in areas with different water improvement years ( P = 0.005), but no statistically significant difference in BMI distribution ( P = 0.154). There was no significant difference in height development level and BMI distribution of children with or without dental fluorosis ( P > 0.05). There were significant differences in serum levels of iron and zinc among children with different height development levels ( P < 0.05). There were significant differences in serum levels of magnesium, copper, iodine and chromium among children with different BMI ( P < 0.05). Conclusion:The growth and development of children in drinking-water-borne endemic fluorosis area after water improvement are not correlated with the prevalence of dental fluorosis, but may be related to the levels of chemical elements such as iron, magnesium, copper, and iodine in the body.

ABSTRACT

Objective:To investigate the onset time distribution and influential factors in patients with acute myocardial infarction (ACI) with different body mass index (BMI) levels.Methods:A cross-sectional study was conducted to collect clinical data from 1 000 patients with AMI who received treatment at Heilongjiang Provincial Hospital from January 2016 to November 2022. The patients were divided into groups based on different BMI levels: < 18.5 kg/m 2 group ( n = 49), 18.5-24 kg/m 2 group ( n = 369), > 24-28 kg/m 2 group ( n = 338), and > 28 kg/m 2 group ( n = 244). The incidence of AMI was analyzed among patients with different BMI levels as per diurnal variation, seasonality, and weekday. Results:A total of 1 000 patients were included in this study, including 648 men and 352 women. The mean age of these patients was 65 years (range 56-74 years). The median body mass was 70 kg (range 60-76 kg), the median height was 1.69 m (range 1.60-1.72 m), and the median BMI was 24.49 kg/m 2 (range 22.22-26.79 kg/m 2). The onset time of AMI differed significantly among patients with different BMI levels in terms of the period from 0:00 to 5:59, winter, and Wednesday ( P = 0.047, 0.029, 0.005). Among all samples, the number of patients with a BMI of 18.5-24 kg/m 2 was the highest, reaching 369 cases. Conclusion:The incidence of AMI in patients with different BMI levels exhibits a regular distribution as per diurnal variation, seasonality, and weekday.

ABSTRACT

Objective:To analyze the independent risk factors for pneumothorax in older adult patients with chronic obstructive pulmonary disease (COPD), construct and validate a prediction model of pneumothorax risk in patients with COPD.Methods:A total of 500 patients with COPD who received treatment at the Department of Emergency, Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from January 2018 to December 2021 were selected using the convenience sampling method and included in this study. Chest CT scan or chest X-ray film findings were used as diagnostic criteria. These patients were divided into a pneumothorax group and a control group according to whether they developed pneumothorax. Taking whether patients develop pneumothorax as a dependent variable and predictive risk factors as independent variables, univariate and multivariate logistic regression analyses of the included risk factors were performed to identify the independent influential factors for developing pneumothorax in patients with COPD. Subsequently, a prediction model for predicting the risk of pneumothorax was constructed and evaluated. A decision curve analysis was conducted to evaluate its clinical practicality.Results:Among 500 patients with COPD, 104 developed pneumothorax, with an incidence of 20.80%. Binary logistic regression analysis showed that long duration of COPD, C-reactive protein, and mechanical ventilation were independent risk factors for the development of pneumothorax in these patients. The percentage of forced expiratory volume in one second (FEV 1%), the FEV 1/forced vital capacity ratio (FEV 1/FVC), and serum albumin are protective factors for the development of pneumothorax in patients with COPD. A prediction model for the risk of developing pneumothorax was constructed. Finally, we obtained the formula: Logit( P) = 12.427 + 2.241 × COPD duration + 0.899 × smoking + 7.715 × CRP + 0.208 × mechanical ventilation history -0.514 × albumin -0.243 × FEV 1%-0.286 FEV 1/FVC. Receiver operating characteristic curve analysis results showed that the area under the curve was 0.815 and the C-Index was 0.781 (95% CI: 0.856-0.891), indicating that the constructed prediction model can better distinguish between patients with and without pneumothorax among those with COPD. Conclusion:C-reactive protein, albumin, FEV 1%, FEV 1/FVC, smoking history, and mechanical ventilation history are all risk factors for the development of pneumothorax. A prediction model has been successfully constructed based on these risk factors, which can effectively predict the risk of pneumothorax. This constructed risk prediction model provides good guidance in taking preventive treatment and nursing measures by medical staff.

ABSTRACT

Objective:To correlate blood lipids and body mass index (BMI) with Helicobacter pylori (Hp) infection. Methods:A total of 303 participants who underwent physical examinations at The 903 Hospital of PLA Joint Logistics Support Force from May 2022 to May 2023 were included in this case-control study. These patients were divided into an Hp-infected group ( n = 97) and a non-Hp-infected group ( n = 206) based on whether they had Hp infection or not. Participants' body height and weight were recorded, and BMI was calculated. The levels of four blood lipid indicators were determined using an automatic biochemical analyzer. The distribution of different BMIs and abnormal statuses of these four blood lipid indicators were compared between the two groups. Spearman correlation analysis was used to analyze the correlation between Hp infection and these four blood lipid indicators. A multivariate logistic regression model was applied to analyze the influential factors for Hp infection. Results:The number of participants who had 24 kg/m 2 ≤ BMI < 28 kg/m 2 [39.17% (38/97)] and the number of participants who had BMI ≥ 28 kg/m 2 [10.31% (10/97)] in the Hp-infected group was significantly higher than those in the non-Hp-infected group [19.90% (41/206) and 2.43% (5/206), χ2 = 12.71, 7.11, P < 0.001, 0.008]. The decrease rate of high-density lipoprotein cholesterol (HDL-C), increase rate of low-density lipoprotein cholesterol (LDL-C), increase rate of triglyceride (TG), and increase rate of total cholesterol (TC) in the Hp-infected group were 23.71% (23/97), 31.96% (31/97), 17.53% (17/97), and 22.68% (22/97), respectively, which were significantly higher than 9.22% (19/206), 11.17% (23/206), 7.28% (15/206), and 8.74% (18/206) in the non-Hp-infected group ( χ2 = 11.59, 19.47, 7.33, 11.19, P = 0.001, < 0.001, 0.007, 0.001). The Spearman analysis showed that Hp infection was linearly positively correlated with BMI, LDL-C, TG, and TC ( r = 0.571, 0.519, 0.473, 0.535, all P < 0.001), while it was linearly negatively correlated with HDL-C ( r = -0.628, P < 0.001). Multivariate logistic regression analysis showed that BMI ≥ 24 kg/m 2, decreased HDL-C, increased LDL-C, elevated TG, and elevated TC are independent risk factors for Hp infection. Conclusion:Blood lipids and BMI are closely associated with Hp infection, and abnormal blood lipids and elevated BMI are independent risk factors for Hp infection.

ABSTRACT

Objective To analyze the disease burden of type 2 diabetes mellitus(T2DM)attributable to high body mass index(BMI)in China from 1990 to 2019 in the context of rapid growth in high BMI rates.Methods Data was extracted from GBD 2019,and the disease burden of T2DM attributable to high BMI in China from 1990 to 2019 was analyzed for overall and subgroups defined by age and sex separately and jointly.The joinpoint regression models were used to analyze the trends of standardized death rate and standardized disability-adjusted life year(DALY)rate.Results From 1990 to 2019,the prevalence of T2DM increased from 2928.78 per 100000 to 6328.79 per 100000 in China.The number of T2DM deaths attributed to high BMI increased from 10500 to 47500 and the standardized death rate increased from 1.25 per 100000 to 2.39 per 100000.The attributed DALY increased from 771800 person-years to 3737600 person-years,and the standardized DALY rate increased from 80.21 per 100000 to 181.54 per 100000.Years of life lost(YLL)and years lived with disability(YLD)and their standardized rates also increased.From 1990 to 2019,the annual average percentage change of the standardized death rate and the standardized DALY rate of T2DM attributable to high BMI were 2.28%and 2.81%,respectively,which were statistically significant(P<0.05)and males were both higher than females.The standardized DALY rate and the standardized death rate of males exceeded that of females in 2010 and 2014,respectively.Age-stratified results showed that the burden of T2DM,which is attributed to a high BMI,is even greater in people over 50 years old.The YLD rate attributable to high BMI increased the most among the 15~49 age group,reaching 323.99%.Conclusion From 1990 to 2019,the disease burden of T2DM that can be attributed to high BMI increased significantly in China.It is necessary to strengthen prevention and control efforts,effectively manage population BMI,and adopt key interventions for high-risk groups to reduce the disease burden of T2DM.

ABSTRACT

Objective:To analyze the association between visceral fat area (VFA) and fatty liver based on quantitative CT (QCT) in people receiving health examination with normal body mass index (BMI).Methods:A cross-sectional study. A total of 1 305 physical examiners who underwent chest CT and QCT examination in the Department of Health Management of Henan Provincial People′s Hospital from January to December 2021 were retrospectively selected as subjects. The physical components at the central level of the lumbar two cone were measured with QCT, including subcutaneous fat area (SFA), VFA and liver fat content (LFC). And the metabolic indexes, such as blood lipids and blood glucose, were collected. The t-test and χ2 test were used to analyze the correlation between the detection rate of fatty live and LFCr and age and gender. According to level of VFA (<100 cm 2, 100-150 cm 2 and≥150 cm 2), the subjects were divided into three groups, and one-way ANOVA and χ2 test were used in comparison between groups. Multiple linear regression was used to analyze the correlation between VFA and metabolic indexes and LFC. Results:Of the 1 305 subjects, there were 634 males and 671 females. The detection rate of fatty liver in normal BMI population was 65.67%, and it was 72.71% and 59.02% respectively in men and women ( χ2=27.12, P<0.001), and the detection rate of fatty liver and LFC increased with age (both P<0.05). With the increase of VFA, the age, BMI, SFA, LFC, total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), fasting blood glucose (FBG), alanine aminotransferase (ALT), blood uric acid and prevalence of fatty liver increased (all P<0.05), and the low-density lipoprotein cholesterol (HDL-C) decreased ( P<0.001). Multiple linear regression analysis showed that after adjustment for age factors, regardless of male or female, LFC was independently positively related with VFA, BMI, and ALT (male β=0.206, 0.145, 0.174, female β=0.194, 0.150, 0.184; all P<0.05). FBG was positively correlated with male independently ( β=0.134; P<0.001). The indicators related to female independently were TC, TG, and blood uric acid ( β=-0.121, 0.145, 0.141, all P<0.05) Conclusion:In the population receiving health examination with normal BMI, the VFA measured by QCT technique is closely related to fatty liver.

ABSTRACT

Objective:To analyze the changes of fasting plasma glucose(FPG)level before and after menopause.Methods:Kailuan health checkup cohort was used to extract data of women aged≥18 years who participated in the first physical examination of Kailuan physical examination cohort and had menopausal age at the end of the seventh physical examination. A total of 3 749 women with 22 057 physical examination records were included in the analysis. Natural logarithmic transformation was applied to FPG, and a segmented linear mixed-effects model was used to analyze the changes in ln-transformed FPG before and after menopause. Additionally, an interaction analysis was performed to assess the multiplicative effect of baseline age and baseline body mass index(BMI)on ln-transformed FPG concerning pre- and post-menopausal periods.Results:The average age of the first physical examination for women in this study was (45.63±4.52)years, the median menopausal age was 51(50~53)years, and the median number of physical examinations was 6(5~7)times. The results of the piecewise linear mixed effect model showed that lnFPG increased from 1 year before menopause, with an average annual increase of 0.021 mmol/L, and continued to increase from menopause to 5 years after menopause, with an average annual increase of 0.007 mmol/L. LnFPG tended to be stable after 5 years of menopause. Baseline age could affect the changes of lnFPG before and after menopause, and there was a negative multiplicative interaction between baseline age ≥45 years and the time period from 6 years to 1 year before menopause( P=0.032). Women with baseline age ≥45 years had a higher average annual increase in lnFPG from 1 year before menopause to 5 years after menopause than women with baseline age <45 years( P<0.05). On lnFPG, there was a positive multiplicative interaction between baseline BMI and time segments around menopause. Compared to women with BMI <24.0 kg/m 2, obese women displayed more annual increase in lnFPG from 6 years to 1 year before menopause as well as from menopause to 5 years after menopause( P<0.05). Conclusions:Menopause has an adverse impact on FPG, with the most significant changes occurring within the period of one year before menopause and up to five years after menopause. Age and BMI significantly influence the changes in FPG before and after menopause.

ABSTRACT

Objective:To investigate the relationship between body mass index(BMI) and osteoporosis using Mendelian randomization analysis.Methods:The genetic variation strongly related to BMI was selected as the instrumental variables in the collection data set of the genome-wide association study(GWAS). The MR-Egger regression, weighted median estimator(WME), inverse variance weighted(IVW), simple mode and weighted mode were used for Mendelian randomization(MR) analysis. The causal association between BMI and osteoporosis was evaluated by odds ratio and 95% confidence interval. The MR-APSS method was applied to make the causal inference results based on MR more reliable. The Linkage disequilibrium score regression was applied to evaluate the genetic correlation, and the horizontal pleiotropy test, heterogeneity test, and leave-one-out method were used to evaluate whether the results were reliable, The influence of heterogeneity and horizontal pleiotropy were reduced by the MR-PRESSO outlier test.Results:A total of 421 SNPs were included, with inverse variance-weighted method as the main analysis approach. The calculated OR value and 95% CI were 0.994(95% CI 0.992-0.997), indicating a protective effect of BMI on osteoporosis. The MR-APSS method showed that the effect of BMI on osteoporosis was statistically significant. Linkage disequilibrium score regression demonstrated a genetic correlation between BMI and osteoporosis. MR-Egger regression intercept showed no horizontal pleiotropy of instrumental variables, and the funnel plot showed no bias in instrumental variables. Leave-one-out analysis confirmed robust results. Conclusion:There may be a negative causal relationship between BMI and osteoporosis and BMI is a protective factor for osteoporosis.
