Overweight status, abdominal circumference, physical activity, and functional constipation in children

SUMMARY OBJECTIVE: The aim of this study was to assess the prevalence of functional constipation and its relationship with the food intake, overweight status, and physical activity of children. METHODS: This cross-sectional study included students from two public schools in the municipality of Osasco, which is located in the metropolitan area of São Paulo. Functional constipation was diagnosed if the clinical manifestations of the Rome IV criteria were present for more than 2 months. A 24-h recall survey was used to determine the daily food intake. Weight, height, abdominal circumference, and bioelectrical impedance were used to evaluate the weight status. Active commuting to school and physical activity scores were assessed using a questionnaire that has been validated in Brazil. RESULTS: A total of 452 children, aged 6-12 years, were evaluated. Functional constipation was observed in 22.3% of participants. A greater abdominal circumference was associated with functional constipation in girls (p=0.036) in the bivariate analysis but not in the logistic regression model. Boys with functional constipation consumed higher quantities of fats (p=0.041). There was no statistically significant relationship between functional constipation and overweight status (44.6 and 34.5% of children with and without constipation, respectively; p=0.083) and active commuting to school (48.5 and 56.7% of children with and without constipation, respectively; p=0.179). CONCLUSION: Functional constipation was associated with a greater abdominal circumference in girls in the bivariate analysis, however, without association in the logistic regression model. Boys with functional constipation consumed higher quantities of fat. No association was found between functional constipation, overweight status, and physical activity.

A study on correlation of sagittal abdominal diameter and blood pressure

Background: Obesity has reached epidemic proportions in our country due to modernization. The distribution of body fat plays an important role in complications due to obesity. Sagittal abdominal diameter (SAD) is considered as an index of abdominal obesity and cardiovascular risk, but its correlation with blood pressure (BP) is poorly understood in our population. Hence, this study is designed. Aims and Objectives: This study aims to measure SAD and to correlate it with neck circumference (NC), systolic BP, and diastolic BP. Materials and Methods: An analytical cross-sectional study was done on 155 participants both males and females attending non-communicable disease outpatient department. Written informed consent was obtained. SAD, NC, and systolic and diastolic BPs were measured. Results: Results were analyzed statistically using Pearson’s correlation coefficient. Positive correlation was obtained for SAD with systolic BP, diastolic BP, and NC. Conclusion: As SAD increases, systolic BP and diastolic BP increase. This shows that SAD is a simple and inexpensive anthropometric parameter to identify early cardiovascular risk. NC is also a valuable tool for the estimation of upper body distribution of fat and helps to identify complications of obesity.

A comparative study of sagittal abdominal diameter and other anthropometric indices of obesity in adults with family history of cardiovascular risk factors

Background:Obesity is evolving into a modern day epidemic in India. Visceral Adipose Tissue is the main culprit, being the metabolically active component that is responsible for the cardiovascular risk factors. The day-to-day anthropometric indices fail to take bodycomposition and distribution into account and hence miss a chance at early detection. Family history plays an important role by serving as a genetic link in the transmission of risk factors. There is a need for vigorous screening techniques which are clinically plausible for an early diagnosis of visceral adiposity in individuals predisposed to the numerous risks caused by its accumulation. Sagittal abdominal diameter is a useful tool in measuring the visceral adipose tissue clinically and in the current study; a comparison was done between SAD and already existing anthropometric indices.Methods:The study was done on 223 subjects in Bangalore during the period of November 2015 to May 2017.Among the subjects studied, 54.7% were Male and 45.3% were female. When compared to BMI, WC andWHR, SAD correlated better with total cholesterol, fasting blood sugar, post prandial blood sugar and HbA1c.Results:The mean SAD was more in people with a combined history of DM and HTN than in individuals with history of either DM or HTN alone. Conclusions:We could conclude that Sagittal Abdominal Diameter is comparable to Body Mass Index, but it correlates better with metabolic risk profile of an individual than BMI, WC andWHR.

Abdominal fat distribution and its relationship to sagittal abdominal diameter (SAD) and SAD-height ratio – An analytical cross-sectional study in the South Indian population

Background: The prevalence of obesity is increasing in developing countries like India. This will place a great burden on the health infrastructure of the country. Early identification and intervention are the keys to managing this important problem. Since Asians tend to have more visceral body fat for any given body mass index (BMI), lower cut-off values have been suggested for different anthropometric parameters. Studies determining the correlation of Sagittal abdominal diameter (SAD) and SAD-height ratio (SADHtR) with total visceral fat volumes measured by computed tomography (CT) scan abdomen quantification are limited in the South Indian population. Aims and Objectives: This study was conducted with the objectives of measuring BMI, SAD, SADHtR, and comparing the correlation of the measured anthropometric parameters with visceral and subcutaneous abdominal fat volumes measured using CT scan abdomen in both the genders in South Indian population. Materials and Methods: This analytical cross-sectional study was done in a hospital setting with a sample size of 566 (276 men and 290 women-aged 30–70 years). Weight, height, and BMI were measured. SAD was measured electronically from a CT image at the L4–L5 level. SADHtR was derived. Total abdominal fat volumes, subcutaneous abdominal fat volumes, and visceral abdominal fat volumes were measured in cm3 from the dome of the liver to the pubic symphysis using software for CT-based quantification of fat volumes between ?190 and ?30 Hounsfield units threshold limits. The data were tabulated and analyzed to compare mean values between men and women and to find the correlation between the anthropometric parameters and visceral fat volume using Pearson’s correlation test. Results: The difference in mean values of BMI, SAD, and SADHtR between the sexes was statistically significant. SAD showed the highest correlation with visceral fat volume in both genders. BMI showed a higher correlation with subcutaneous adipose tissue volume than with visceral adipose tissue volume. Conclusion: Both SAD and SADHtR can be used as simple and reproducible anthropometric tools to identify the presence of increased visceral fat volume in both genders in our population.

Biometría fetal del segundo trimestre: predicción de nacimientos pequeños y grandes para la edad gestacional

Introducción: La biometría médica ha permitido identificar variables predictoras del peso al nacimiento. Objetivo: Determinar el poder discriminatorio local y desempeño de variables biométricas fetales a las 22 semanas sobre la condición trófica del recién nacido. Métodos: Se realizó estudio observacional, analítico y retrospectivo en tres áreas de salud del municipio Santa Clara, en el período comprendido entre enero de 2013 a diciembre de 2019. De una población de 6 035 nacidos se seleccionaron 2 454 por muestreo simple aleatorio. Se obtuvieron datos de registros de las consultas de genética. En el análisis se construyeron áreas bajo la curva Receiver Operating Characteristic y se calcularon indicadores de desempeño para pruebas diagnósticas. Resultados: Las áreas bajo la curva de las variables biométricas discriminan a los nacidos pequeños y grandes para la edad gestacional. En los pequeños sobrepasan a los 0,840 a excepción de la longitud del fémur; en los grandes el peso fetal estimado alcanza una curva de 0,715 el resto son inferiores. Se estiman puntos de corte locales. Los indicadores de desempeño de la biometría mantienen un comportamiento regular; los que se estiman al transformar los valores a partir de las tablas de referencia son más específicos con valores por encima del 80 %; mientras que los calculados después de transformar las variables por los puntos de corte estimados elevan la sensibilidad por encima del 60 %. Conclusiones: Todas las variables biométricas tienen capacidad discriminatoria para las desviaciones de la condición trófica al nacer, de preferencia para los nacimientos pequeños para la edad gestacional. Los puntos de corte óptimo identificados difieren de los establecidos en las tablas de referencias. Los indicadores de desempeño de las variables biométricas fetales demostraron superioridad según los puntos de corte estimados respecto a los de las tablas de referencia.

Introduction: Medical biometrics has made it possible to identify predictive variables of birth weight. Objective: To determine the local discriminatory power and performance of fetal biometric variables at 22 weeks on the trophic condition of the newborn. Methods: An observational, analytical and retrospective study was carried out in three health areas of the Santa Clara municipality, in the period between January 2013 and December 2019. From a population of 6,035 births, 2,454 were selected by simple random sampling. Data were obtained from records of genetic consultations. In the analysis, areas under the Receiver Operating Characteristic curve were constructed and performance indicators for diagnostic tests were calculated. Results: The areas under the curve of the biometric variables discriminate those born small and large for gestational age. In the small ones they exceed 0.840 except for the length of the femur; in the large ones, the estimated fetal weight reaches a curve of 0.715, the rest are lower. Local cut-off points are estimated. The performance indicators of the biometrics maintain a regular behavior; those that are estimated by transforming the values ​​from the reference tables are more specific with values ​​above 80%; while those calculated after transforming the variables by the estimated cut-off points raise the sensitivity above 60%. Conclusions: All biometric variables have discriminatory capacity for deviations of the trophic condition at birth, preferably for small births for gestational age. The optimal cut-off points identified differ from those established in the reference tables. The performance indicators of the fetal biometric variables showed superiority according to the estimated cut-off points with respect to those of the reference tables.

Methods of predicting visceral fat in Brazilian adults and older adults: a comparison between anthropometry and computerized tomography

Visceral adipose tissue (VAT) is linked with the metabolic consequences of obesity, being necessary the use alternative methods of predicting this type of fat, like anthropometry. The objective of this study was assess the performance of anthropometry in predicting visceral fat measured with computerized tomography in adults and older adults. Study transversal with 197 individuals underwent computerized tomography (CT) and anthropometry. The variables analized were: visceral adipose tissue area by CT, Sagittal Abdominal Diameter (SAD), Waist Circumference (WC) and Waist-Hip Ratio (WHR). A descriptive analysis, Pearson correlation and ROC curve were carried out. We observed Correlations higher than 0.7 (p=0.000) between the SAD, WC and the VAT area were found in adult men and older men and in adult women. WHR displayed the least correlations. The most sensitive and specific SAD cut-off points were equal for all the men (Adults: 20.2 cm /Older adults: 20.2 cm) but different for the women (Adults: 21.0 cm; sens.: 83.3; spec.: 79.1 /Older adults: 19.9 cm; sens.: 81.0; spec.:79.3). The WC cut-off points that identified a VAT area =130cm² were 90.2 cm and 92.2 cm for men (adult men - sens.: 86.7; spec.: 86.1 - and older men- sens.: 79.3; spec.: 77.8 -respectively), while for women the recorded values were 92.3 cm (adult women- sens.: 83.3; spec: 81.4) and 88.2 cm (older women - sens.:76.2; spec.: 69.0).This study showed that WC and SAD achieved the best performance in the identification of visceral fat considered at risk for the development of cardiometabolic diseases in adults and older adults.

Usefulness of Sagittal Abdominal Diameter for Evaluation of Metabolic Syndrome and Insulin Resistance / 가정의학회지

BACKGROUND: We studied the association of sagittal abdominal diameter (SAD) and metabolic syndrome and insulin resistance in Korean adults. METHODS: This is a cross-sectional study by 190 patients who visited a Health Promotion Center of National University of Pusan from 11 November to 14 November, 2008. We analyzed the association of anthropometry (waist circumference, BMI, SAD), insulin resistance (homeostatic model assessment-insulin resistance, HOMA-IR), insulin sensitivity (quantitative insulin sensitivity check index, QUICKI), and plasma concentrations of glucose, insulin, total cholesterol, LDL, HDL, triglyceride. SAD was categorized into quartiles and assessed odds ratio of metabolic syndrome adjusted for age, sex, lifestyle factors. RESULTS: SAD showed significance correlation to HOMA-IR than BMI. Quartiles of SAD showed a positive trend with metabolic risk factors including abdominal obesity, high blood pressure, HOMA-IR and obesity but hypertriglyceridemia, low HDL-cholesterolemia did not show significant association. In men QUICKI was significantly high. A multivariate model, adjusted for age, sex, smoking status, physical activity, heavy drinking, HOMA-IR and QUICKI, revealed a progressively increased odds ratio of metabolic syndrome, 3rd quartile (odds ratio [OR]; 9.467; 95% confidence interval [CI], 3.225 to 27.789; P < 0.001) and 4th quartile (OR, 7.253; 95% CI, 2.437 to 21.586; P < 0.001), with increasing SAD. CONCLUSION: As shown above, SAD was a strong anthropometric marker of insulin resistance, risk of metabolic syndrome and decreased insulin sensitivity in Korean adults.

OBJETIVOS: Avaliar a habilidade de indicadores antropométricos e de composição corporal em identificar a resistência à insulina (RI), determinando-se os pontos de corte para os que apresentarem melhor eficácia. MÉTODOS: Foram avaliados 138 homens. Determinou-se: perímetro da cintura (PC), diâmetro abdominal sagital (DAS), índice de conicidade (IC), índice de massa corporal (IMC), percentual de gordura corporal ( por centoGC), índice sagital (IS) e relações cintura-estatura (RCE), cintura-quadril (RCQ) e cintura-coxa (RCCoxa). A RI foi avaliada pelo HOMA-IR. Utilizou-se análise de correlação e análise ROC, com determinação das áreas abaixo da curva (AUC). RESULTADOS: O DAS (r = 0,482; AUC = 0,746) e o PC (r = 0,464; AUC = 0,739) apresentaram correlações mais fortes com o HOMA-IR e maior poder discriminante para RI (p < 0,001), sendo seus melhores pontos de corte 89,3 cm e 20,0 cm, respectivamente. CONCLUSÃO: Os indicadores de obesidade central, o PC e o DAS demonstraram maior habilidade em identificar RI em homens. Encoraja-se a realização de estudos com mulheres e idosos na busca dos melhores pontos de corte para toda a população.

OBJECTIVE: To assess the ability of anthropometric and body composition indicators in identifying insulin resistance (IR), determining cut-off points for those showing the best efficacy. METHOD: 138 men were evaluated. Waist perimeter (WP), sagittal abdominal diameter (SAD), conicity index, body mass index (BMI), body fat percent, sagittal index, and the waist-to-height, waist-to-hip and waist-to-thigh ratios were determined. IR was assessed by the HOMA-IR index. Statistical analysis consisted of Spearman correlation coefficient and ROC (receiver operating characteristic) curves, calculating the area under the curve (AUC). RESULTS: SAD (r=0.482, AUC=0.746) and WP (r=0.464, AUC=0.739) showed stronger correlations with the HOMA-IR and greater ability to identify IR (p<0.001), being 89.3 cm and 20.0 cm the best cut-offs, respectively. CONCLUSION: The anthropometric indicators of central obesity, WP and SAD, have shown greater ability to identify IR in men. We encourage studies in women and elderly people in search of the best cut-off points for the entire population.
