Impact of anthro-metabolic indices and gestational weight gain on maternal and neonatal outcomes: a prospective observational study

SUMMARY OBJECTIVE: The aim of this study was to examine the relationship of anthro-metabolic indices on maternal and neonatal outcomes. METHODS: This prospective observational study was conducted on healthy mother-baby pairs between January 1, 2023 and July 1, 2023. Detailed sociodemographic information was collected through an interview with the mother. Clinical, biochemical, obstetric, fetal, and neonatal outcomes were abstracted from hospital medical records. Anthropometric measurements were obtained from the examination of mother-baby pairs. RESULTS: A total of 336 healthy mothers-children pairs were included. Mothers of newborn ≥4000 g had higher gestational age (p=0.003), body mass index (p=0.003), gestational weight gain (p=0.016), waist circumferences (p=0.002), and hip circumferences (p=0.001). gestational weight gain was associated with the mode of delivery (p=0.023). waist-to-hip ratio (p=0.005), gestational weight gain (p=0.013), and a body shape ındex (p<0.001) were associated with longer length of hospital stay. Age (p<0.001) and inter-pregnancy interval (p=0.004) were higher in pre-pregnancy underweight/obese mothers. Receiver operating characteristic analysis revealed that maternal waist circumferences (AUC: 0.708, p=0.005), maternal weight (AUC: 0.690, p=0.010), and hip circumferences (AUC: 0.680, p=0.015) were sufficient to predict macrosomia (p<0.05). CONCLUSION: The study demonstrated a significant association between gestational weight gain and cesarean delivery, prolonged hospital stay, and macrosomia. It was also found that maternal body mass index, waist circumferences, and hip circumferences during pregnancy were associated with macrosomia. On the contrary, no significant relationship was found between maternal anthro-metabolic characteristics and maternal-fetal and birth outcomes.

Correlation of waist-to-hip ratio with smoking and hypertension in coronary artery disease patients: Report from a tertiary care hospital in Bihar

Background: Obesity, especially central obesity has been proved to be a risk factor for overall deterioration of health with emphasis on cardiovascular disease. Aim and Objectives: In this study, we aimed to find if there is any correlation between waist-to-hip ratios with smoking and hypertension in patients from a tertiary care hospital in Bihar. Materials and Methods: After taking permission from the institutional ethics committee, this study was conducted in the department of physiology and medicine in a tertiary care hospital in Bihar. Coronary artery disease patients were recruited from the in-patient department of medicine department. The waist circumference and hip circumference were measured by fiberglass measuring tape to the nearest 1 cm. The smoking history and history of hypertension were obtained. Results: A total of 75 patients (57 male and 18 female) were included in the study. There was 26 (34.67%) smoker and 49 (65.33%) non-smoker. Among the patients 34 (45.33%) were suffering from hypertension and 41 (54.67%) patients did not suffer from hypertension (?2 = 0.15, z = 0.38, P = 0.70). There was no gender difference in waist-to-hip ratio (WHR) (t = 0.4553, P = 0.65). Among the patients, WHR, smoking, and hypertension did not show any significant correlation. Conclusion: Among the coronary patients, there was no correlation of WHR with smoking and hypertension. Even smoking and hypertension did not show any relationship. Hence, obesity, smoking, and hypertension should be considered as individual risk factors for coronary artery disease.

Consumo de bebidas alcoólicas e obesidade abdominal: resultados da linha de base do ELSA-Brasil / Consumption of alcoholic beverages and abdominal obesity: cross-sectional analysis of ELSA-Brasil

Resumo Objetivou-se analisar a associação entre consumo de bebidas alcoólicas e adiposidade abdominal em adultos. Estudo transversal realizado com dados da linha de base do ELSA-Brasil (2008-2010). A amostra foi constituída por 15.065 servidores públicos de seis instituições de ensino e pesquisa (35 a 74 anos, ambos os sexos). Para identificar adiposidade central por meio das medidas de circunferência da cintura (CC) e relação cintura/quadril (RCQ), utilizou-se os pontos de corte preconizados pela Organização Mundial da Saúde. Para as análises estatísticas foi utilizado o teste qui-quadrado e modelos de regressão de Poisson ajustados por variáveis potencialmente confundidoras. Cerca de 40% da amostra apresentava CC e RCQ elevadas. A probabilidade de apresentar CC elevada foi 5% e 3% maior no grupo mais exposto de consumo de cerveja em homens e mulheres quando comparado ao grupo de referência [RP = 1,05 (IC 95% 1,02-1,08) e RP = 1,03 (IC 95% 1,00-1,07)]. Também foi encontrada maior probabilidade de apresentar RCQ elevada entre os maiores consumidores de cerveja [RP = 1,03 (IC 95% 1,00-1,07) em homens e RP=1,10 (IC 95% 1,04-1,15) em mulheres]. Maior número de doses/semana de bebida alcoólica aumentou a probabilidade de ocorrência de CC e RCQ elevadas, sendo mais importante a contribuição da cerveja.

Abstract The objective was to analyze the association between alcohol consumption and abdominal adiposity in adults. Cross-sectional study conducted at baseline data from ELSA-Brasil (2008- 2010). The sample consisted of 15,065 civil servants from six education and research institutions (35 to 74 years old, both sexes). To identify central adiposity by measuring waist circumference (WC) and waist-to-hip ratio (WHR), the cutoff points recommended by the World Health Organization were used. Poisson regression models adjusted for potentially confounding variables were tested. About 40% of the sample had elevated WC and WHR. The probability of having elevated WC was 5% and 3% higher in the most exposed group of beer consumption in men and women when compared to the reference group [PR= 1.05 (95% CI 1.02-1.08) and P R= 1.03 (95% CI 1.00-1.07)]. A higher probability of having a high WHR was also found among the highest beer consumers [PR = 1.03 (95% CI 1.00-1.07) in men and PR = 1.10 (95% CI 1.04-1.15) in women]. A greater number of doses/week of alcoholic drink increased the probability of occurrence of high WC and WHR, with the beer contribution being more important.

ABSTRACT Objectives (i) To assess the anthropometric measurements, along with the clinical characteristics and quality of life profiles of the studied patients; (ii) To determine the occurrence and severity of Obstructive Sleep Apnea (OSA), using polysomnography; and (iii) To identify the best anthropometric and clinical indicators to predict OSA in obese patients who are candidates for bariatric surgery. Methods a prospective observational study conducted in a private clinic, using consecutive sampling of patients eligible for bariatric surgery with a BMI ≥ 40, or with a BMI of ≥ 35 kg/m² accompanied by comorbidities associated with obesity. Results Sixty patients were initially selected, of whom 46 agreed to take part in the preoperative evaluation. OSA was observed in 76% of patients, 59% of whom had moderate-to-severe OSA, with a predominance of men in these groups. Among the variables suggesting statistical difference between groups, waist-to-hip ratio (WHR) was the only clinical factor associated with scores the apnea hypopnea index (AHI) ≥ 15, with a cut-off value of 0.95. The results showed that patients scoring above 0.95 are three times more likely to have moderate-to-severe apnea. Conclusion The best risk factor for the prognostic of moderate-to-severe OSA was presenting a WHR score with a cut-off value of 0.95 or above.

RESUMO Objetivos (i) Avaliar as medições antropométricas e as características clínicas e perfis de qualidade de vida dos pacientes estudados, (ii) determinar a ocorrência e severidade da Apneia Obstrutiva do Sono (AOS) por meio de polissonografia e (iii) identificar os melhores indicadores antropométricos e clínicos para prever a AOS em pacientes obesos que são candidatos à cirurgia bariátrica. Métodos Estudo prospectivo de observação conduzido em uma clínica particular, por meio de amostragem consecutiva de pacientes qualificados para cirurgia bariátrica com IMC ≥ 40 ou IMC de ≥ 35 kg/m² e comorbidades associadas à obesidade. Resultados Inicialmente, 60 pacientes foram selecionados, dos quais 46 concordaram em participar de avaliação pré-operatória. A AOS foi observada em 76% dos pacientes, sendo que 59% deles apresentavam AOS de moderada a grave, com uma predominância de homens nesses grupos. Entre as variáveis que sugerem diferença estatística entre os grupos, a relação cintura/quadril (RCQ) foi o único fator clínico associado à pontuação no índice de apneia-hipopneia (IAH) ≥ 15, com um valor de corte de 0.95. Os resultados mostram que pacientes com uma pontuação acima de 0,95 têm três vezes mais probabilidade de apresentarem apneia de moderada a grave. Conclusão O melhor fator de risco para o prognóstico de AOS de moderada a grave foi apresentado na pontuação de RCQ, com um valor de corte de 0,95 ou acima.

Prevalence of prediabetes in children and its association with risk factors

Background: Type 2 Diabetes is becoming more common at younger age group. It is important to screen children and adolescents for prediabetes to prevent long-term complications of diabetes. This study was conducted to study the prevalence of prediabetes in children and its association with risk factorsMethods: It is a Prospective hospital-based study. Children aged 6 to 18 years admitted in the Pediatric ward of tertiary care hospital were included. Study was done over a period of 2 years November 2015-October 2017. Participants were screened to find out the prevalence of prediabetes. Prediabetes was defined as fasting glucose concentration (FBS)of 100-125 mg/dl or a HbA1c value of between 5.7% and 6.4%, or a two-hour post-glucose tolerance concentration (OGTT) of 140-199mg/dl.Results: 607 children participated in the study.56.3% were males. Prevalence of Prediabetes was 20.4% with a combination of OGTT, FBS and HbA1c tests. Prevalence by OGTT was 5.9%, HbA1c 4.1% and by FBS was 17.1%. Higher prevalence of prediabetes was associated with male gender, frequent consumption of junk foods, decreased physical activities, overweight, obesity and high waist to hip ratio. Combination of FBS with GTT and FBS with' HbA1c had better sensitivity and specificity when compared to combination of OGTT with HbA1c .Conclusion: Screening of children for prediabetes at younger age especially those with risk factors and intervention with lifestyle modification may help in delaying the progression of the disease.

Correlación entre el índice tobillo brazo y la circunferencia abdominal en pacientes de la consulta de medicina interna / Correlation of ankle-brachial-index and waist circumference in ambulatory patients of internal medicine

La enfermedad arterial periférica (EAP) es usualmente subdiagnosticada. El índice tobillobrazo (ITB) es un método diagnostico sencillo y no invasivo que permite hacer detección temprana de EAP y de aquellos pacientes con alto riesgo de desarrollar ECV. Objetivo: determinar la relación entre ITB y obesidad visceral mediante la medición de la circunferencia abdominal (CA) en pacientes que acudieron a la consulta externa de Medicina Interna. Otras mediciones: índice de masa corporal (IMC), relación cintura cadera (RCC). Se registró la presencia de hipertensión arterial (HTA), dislipidemia, sedentarismo y tabaquismo.

El 70% tenían IMC elevado, 64,7% dislipidemia, 52,9% HTA, 38.23% sedentarismo y 17,6% fumaban. 5 pacientes masculinos tuvieron un ITB alterado: ITB bajo: 2; ITB elevado: 3. La correlación entre ITB y CA; ITB y RCC e ITB y glicemia, TGC y el LDL fue negativa débil. La correlación entre ITB e IMC, colesterol total y HDL fue positiva. Conclusiones: Una CA y RCC alteradas como marcadores de obesidad visceral se asocian con un ITB bajo(AU)

Peripheral arterial disease (PAD) is associated to high cardiovascular morbidity and mortality. Risk factors related to this pathology do not differ from other cardiovascular diseases (CVD). This disease manifests clinically in advanced stages of the atherothrombotic process, therefore, it is usually underdiagnosed. The ankle-brachial index (ABI) is a simple, inexpensive and non-invasive diagnostic method that allows an early detection of PAD, and, because it is considered atherosclerotic predictor, it helps us detect those patients who have a high risk of developing CVD. Hence, it should be a routine method in clinical practices. Objectives: This study was performed in order to determine the relationship between ABI and visceral obesity by means of waist circumference (WC) measurement and hip to waist ratio (HWR) in patients who attended the internal medicine outpatient clinic. Methods: Exploratory research. Non-probabilistic, intentional sample of 34 patients who attended the Internal Medicine outpatient clinic in three months. A survey was applied and measurements were made of the anthropometric indexes: CA, RCC, BMI, ITB was calculated and glycemia, total cholesterol, HDL, LDL and triglycerides were determined. Results: The average age was 56.14 years ± 11.46. 52.9% women and 47.1% men. 70% had high BMI, 64.7% dyslipidemia, 52.9% HBP, 38.23% sedentary lifestyle and 17.6% smoked. 5 male patients had an altered ABI: low ABI: 2; High ITB: 3. The correlation between ITB and CA; ITB and RCC and ITB and glycemia, TGC and LDL were weak negative. The correlation between ITB and BMI, total cholesterol and HDL was positive. Conclusions: A CA and RCC altered as markers of visceral obesity are associated with a low ABI(AU)

Lifestyle Predictors Of Overweight Among Malaysians

@#he epidemic of overweight is encroaching in the world today, irrespective of economic and social status and regions. It is now seen as a public health threat and one that must be taken seriously in all aspects of public health interventions. There is a need to deeper understand the relationship of lifestyle behaviors and the epidemic of overweight and obesity. This cross-sectional study investigates the lifestyle predictors (smoking, physical activity, diet, and sleeping) of overweight as measured by body mass index (BMI) and waist-to-hip ratio (WHR). A questionnaire survey was conducted among 459 samples (18 years old and above) from those who attended a health screening drive, conducted in three major regions in Peninsular Malaysia. Data were analyzed using descriptive statistics as well as regression model, with p<0.05 considered significant. The overall Body Mass Index (BMI) of the population was overweight at 24.69 while the Waist-to-Hip ratio (WHR) for female was 0.86, classified as high and for male, 0.94 which was borderline. Predictor model revealed that smoking (P<0.05, R2 - 0.38) and physical activity (P=0.02, R2 - 0.11) were predictors for body mass index while smoking P<0.05, R2 - 0.50) was a predictor of Waist-to-hip ratio. Findings showed that the problem of overweight in Malaysia is real and smoking and physical activity play a strong role and need to be considered in any public health interventions.

Anthropometry and body composition of adolescents in Macedonia / Antropometría y composición corporal de adolescentes en Macedonia

The aim of this research was to determine the level of adiposity and obesity among Macedonian adolescents and to compare the results with previous studies conducted in this population, as well as those conducted in other populations. The sample included 2390 adolescents from four urban different regions of R. Macedonia aged between 11 to 18 years; 1238 males and 1152 females. Weight, height, waist, and hip circumference (WC, HC) as well as triceps, calf, subscapular, and suprailiac skinfold thickness (SFT) were measured. Body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), subscapular/triceps skinfold ratio (STR), and percentage body fat were computed. The prevalence of overweight and obesity defined by the IOTF children growth reference were calculated and age-dependent and gender-specific smoothed percentile curves for BMI and ROC curves were generated. The boys have statistically significantly higher values of WC, WHR and WHtR in all adult categories (except WHtR at 18 years old), greater body weight at the age of 12 to 18, and body weight 13 to 18 years (p<0.001). Weight, height and BMI are increasing with age in both, boys and girls, and decreases in girls. The level of adiposity of Macedonian adolescents has increased over the past 20 years and has reached the level of developed countries that face an obesity epidemic.

El objetivo de esta investigación consistió en determinar el nivel de adiposidad y obesidad entre los adolescentes macedonios y comparar los resultados con estudios previos realizados en esta población, así como aquellos realizados en otras poblaciones. La muestra incluyó a 2390 adolescentes de cuatro regiones urbanas diferentes de R. Macedonia con edades comprendidas entre 11 y 18 años (1238 hombres y 1152 mujeres). Se midieron el peso, la altura, la cintura y la circunferencia de la cadera (WC, HC), así como el grosor del pliegue cutáneo tríceps, pantorrilla, subescapular y suprailíaco (SFT). Se calcularon el índice de masa corporal (IMC), la relación cintura-cadera (WHR), la relación cintura-altura (WHtR), la relación de pliegue subcutáneo / tríceps (STR) y el porcentaje de grasa corporal. Se calcularon las prevalencias de sobrepeso y obesidad definidas por la referencia de crecimiento de niños IOTF y se generaron curvas percentiles suavizadas dependientes de la edad y de sexo para las curvas BMI y ROC. Los niños tuvieron valores estadísticamente significativamente más altos de WC, WHR y WHtR en todas las categorías de adultos (excepto WHtR a los 18 años), mayor peso corporal a la edad de 12 a 18 años y peso corporal de 13 a 18 años (p <0,001). El peso, la estatura y el IMC aumentan con la edad tanto en niños como en niñas y disminuyen en las niñas. El nivel de adiposidad de los adolescentes macedonios ha aumentado en los últimos 20 años y ha alcanzado el nivel de los países desarrollados que enfrentan una epidemia de obesidad.

Adiposity and Cortisol Response to Stress in Indian Adolescents

Objective: We examined associations of different adipositymeasures with cortisol responses during the Trier Social StressTest for children (TSST-C).Design: Descriptive study.Setting: Holdsworth Memorial Hospital, Mysore, India.Participants: Adolescents aged 13.5y from a birth cohort wererecruited (N=269, 133 boys).Methods: The stressor (TSST-C) was 5-minutes each of publicspeaking and mental arithmetic tasks in front of two unfamiliar‘judges’. Salivary cortisol concentrations were measured atbaseline and at regular intervals after TSST-C. Weight, height,sub scapular and triceps skinfold thickness, and waist and hipcircumference were measured, and percentage body fat wasestimated (fat%; bioimpedance). Body mass index (BMI) andWaist-to-hip ratio (WHR) were calculated. All variables wereconverted into within-cohort SD scores before analysis. Stress-induced change in cortisol concentrations from baseline (cortisolresponse) was examined in relation to adiposity.Results: Stress increased cortisol concentrations significantlyfrom baseline (mean (SD): 5.5 (6.4) ng/mL; P<0.001). HigherWHR was associated with lower cortisol response at 20 and 30-minutes after stress (~0.13 SD decrease in cortisol response perSD higher WHR, P<0.05). Higher fat% was also associated withlower cortisol response only in girls 20-minutes post-stress (0.23SD lower response per SD higher fat%, P=0.004). Sum of skinfoldthickness and BMI were not associated with cortisol responses.Conclusions: Abdominal adiposity is associated with reducedhypothalamic-pituitary-adrenal axis reactivity to stress in thisadolescent population.

Anthropometric Characteristics of Korean Patients with Obstructive Sleep Apnea

BACKGROUND AND OBJECTIVES: Obesity is one of the most important risk factors for obstructive sleep apnea (OSA). There is limited evidence regarding the obesity-related anthropometric characteristics of Korean patients. MATERIALS AND METHOD: Medical records of 984 patients referred to 3 tertiary referral hospitals for habitual snoring or sleep apnea were analyzed. We defined OSA as apnea-hypopnea index (AHI) ≥5 and analyzed data to determine the anthropometric characteristics of patients with OSA such as neck circumference (NC), waist circumference (WC), hip circumference (HC), and waist to hip ratio (WHR). RESULTS: A total of 952 patients (719 men) were included in the analysis. The main findings were: 1) BMI, WC, NC, HC, and WHR were greater among patients with OSA than among controls (AHI 50 years; 3) WC and WHR were most strongly correlated with AHI for men and women, respectively. CONCLUSION: OSA is associated with anthropometric characteristics, although different patterns were observed between men and women. OSA was more strongly associated with NC or WC among men and with WHR among women.

Cintura e índice de masa corporal: los mejores predictores antropométricos en la reducción y progresión de la agregación de factores de riesgo cardiometabólicos / Waist and body mass index: The best anthropometric predictors in the reduction and progression of the aggregation of cardiometabolic risk factor

El objetivo de este estudio fue determinar el impacto de la variación de distintas mediciones antropométricas en la evolución del síndrome metabólico (SM). El estudio fue prospectivo en 178 sujetos que asistieron a un programa de salud cardiovascular entre el año 2013 y 2016. Se recolectaron datos demográficos, historia médica, factores de riesgo cardiovascular, y se midió perfil lipídico, glicemia de ayuno, presión arterial y medidas antropométricas (IMC, perímetro de cintura y cadera y % de grasa corporal). Se consideró la agregación de 2 o más componentes de síndrome metabólico (SM), excluyendo cintura y se determinó la probabilidad de reversión del SM, considerándose como la reducción desde 2 o más componentes a 1 o ninguno. El tiempo de seguimiento promedio fue de 2 años. La edad promedio fue de 40 años y 37% eran mujeres. Según los modelos de odds proporcionales, ajustados por edad, sexo y tiempo de seguimiento, aquellos sujetos con 2 o más componentes de SM triplicaron su probabilidad de revertir el SM por cada reducción de 1 Kg/m2 de IMC por año (OR IMC = 3,03; 1,74-5,28; p<0,001). En el caso de cintura, esta probabilidad aumentó en 52% por la reducción de 1 cm por año (ORcintura =1,52; 1,28-1,81; p<0,001). Finalmente una reducción de 0,01 en el índice cintura/cadera aumentó en 26% la probabilidad de revertir el SM (ORcintura/cadera =1,26; 1,06-1,491; p<0,01); sin embargo, el % de grasa corporal no tuvo un efecto significativo Los cambios en IMC y circunferencia de cintura serían los parámetros antropométricos más confiables para monitorear la evolución del SM(AU)

The objective of this study was to determine the impact of variation of different anthropometric parameters at follow-up in the evolution of the metabolic syndrome (MetS). Prospective study in 178 subjects who attended a cardiovascular health program between 2013 and 2016. Demographical data, medical history and cardiovascular (CV) risk factors (RFs) were collected. In addition, fasting lipid profile, blood glucose, blood pressure and anthropometrical parameters (BMI, WC, hip, and fat percentage) were measured. To determine the evolution of MetS, the clustering of 2 or more of the MetS components were considered, excluding WC. Odds proportional models adjusted by age, sex and time of follow-up were built to determine the probability of reverting the MetS. MetS reversion was considered as the reduction to 1 or 0 components in subjects with 2 or more. Mean follow-up time was 2 years. Mean age was 40 years old and 37% were women. According to the odds proportional models, subjects tripled their chance of reverting MetS for each 1 kg/m2 of BMI reduction (ORBMI=3.03; 1.74-5.28; p<0.001). For WC, the chance of reverting MetS increased 52% for each reduction of 1 cm of waist (ORwaist =1.52; 1.28-1.81; p<0.001). A reduction of 0.01 in the waist to hip ratio increased in 26% the chance of reverting MetS (ORwaist/hip=1.26; 1.06-1.491; p<0.01); however, fat percentage did not have a significant effect on the evolution of the MetS. BMI and WC are the most reliable anthropometrical parameters for monitoring the evolution of MetS aggregation in the out-patient clinical setting(AU)

Predictive Value of Obesity Index to the Metabolic Syndrome among Tianjin Adults / 中国医科大学学报

Objective To explore the predictive value of obesity-related index for metabolic syndrome(MS)among Tianjin adults. Methods A total of 522 adults who participated in a physical examination were included in this cross-sectional study. Participants 'gender and age were record-ed,height,weight,waist circumference(WC)and hip circumference were measured,and TC,TG,HDL-C and FPG were tested. The receiver op-erating characteristic(ROC)curves were generated to identify the optimal measurement of obesity for the prediction of metabolic risk in this popu-lation. Results The area under the ROC curve(AUC)value for waist-to-height ratio(WHtR)predicted the maximum value of MS,followed by WC and BMI,and WHR was the lowest. The optimal cut off value of WHtR was 0.509. There was significant difference in the ability of BMI be-tween different age groups and WC to predict MS. In the groups of<40 years old and≥60 years old,BMI had higher predictive value for MS than WC. Conclusion WHtR has the best predictive value for evaluating the MS risk compared to BMI ,WC or WHR alone among Tianjin adults. The predictive value of BMI and WC for evaluating the MS risk can be improved by the method of age stratification.

Cardiorespiratory Fitness, Physical Activity Level, Body Mass Index And Blood Pressure Among University Students In Negeri Sembilan

@#Noncommunicable diseases are the number one killer globally and it could develop due to various risk factors. This cross-sectional study was aimed to identify these risk factors by assessing body mass index, waist circumference, waist to hip ratio and blood pressure and to find out the correlation between these risk factors, and cardiorespiratory fitness and physical activity level. The study samples were 103 students from two universities in Negeri Sembilan state selected by the convenience sampling method. After ethical clearance, International Physical Activity Questionnaire-short form in English was used to assess the physical activity level. The cardiorespiratory fitness was assessed by the Rockport one mile walk test and the other parameters were assessed following the standard protocols. The percentage of overweight (32.04%) and pre-hypertension (25.24%) were higher among students. 35.92% of students reported a low physical activity level and 46.6% having a lower fitness level (fair and poor). The physical activity level correlated with the cardiorespiratory fitness level (P<0.01). The body mass index (P<0.01) and systolic blood pressure (male P 0.05, female P<0.01) negatively correlated with the cardiorespiratory fitness level. Therefore, measures have to be taken to improve the physical activity level and cardiorespiratory fitness to lower the risk of overweight and high blood pressure among university students.

Optimal Cutoffs of Cardiometabolic Risk for Postmenopausal Korean Women

PURPOSE: The purpose of the study was to identify the optimal cutoff values of indices for cardiometabolic risk in postmenopausal Korean women. Specifically, we intended to determine the cutoffs of waist circumference, waist-to-hip ratio (WHR), serum lipid profile, and homeostatic model of assessment-insulin resistance (HOMA-IR) for detecting metabolic syndrome (MetS), and metabolic obesity (MO). METHODS: The study participants were 397 postmenopausal women. We defined MetS and MO with the International Diabetes Federation criteria except for waist circumference. A receive operating characteristic curve analysis was used to assess the accuracy of diagnostic indices for identifying MetS and MO. Cutoff values were obtained both from the point on the receive operating characteristic curve which was closest to (0,1) and from the Youden's index. RESULTS: Among the participants, 34.5% and 73% were classified as having MetS and MO. The optimal cutoff of waist circumference and WHR were 81.9 cm [area under curve (AUC): 0.687, sensitivity: 61.7%, specificity: 68.9%], 0.87 (AUC: 0.660, sensitivity: 64.7%, Specificity: 60.2%) for MetS and 77.4 cm (AUC: 0.655, sensitivity: 65.6%, specificity: 57.8%), 0.86 (AUC: 0.680, sensitivity: 67.0%, specificity: 62.7%) for MO. Triglyceride to high-density lipoprotein ratio for MetS and MO were 2.11 (AUC: 0.838, sensitivity: 71.5%, specificity: 79.6%) and 1.59 (AUC: 0.725, sensitivity: 65.9%, specificity: 68.2%) respectively. The HOMA-IR for MetS was 1.36 (AUC: 0.773, sensitivity: 73%, specificity: 71.9%) and for MO was 1.17 (AUC: 0.713, sensitivity: 64.5%, specificity: 69.2%). CONCLUSIONS: For postmenopausal women, we suggest waist circumference of 81.9 cm and WHR of 0.87 as criteria of MetS. However, women with waist circumference over 77.4 cm and WHR over 0.86 should be monitored for the future development of MetS.

Dietary Diversity Score and Its Related Factors among Employees of Kermanshah University of Medical Sciences

Dietary diversity score (DDS) is known as an indicator of food quality. Dietary diversity can promote health status. The aim of this study was determined DDS and its related factors in Kermanshah University of Medical Sciences (KUMS) employees. This cross-sectional study was conducted on 190 employees of KUMS in 2015. According to the population of KUMS centers which were selected randomly (Paramedical, Public Health faculties, Imam Reza Hospital and province health center), subjects were selected by convenience sampling method. Food frequency questionnaire (FFQ) was used to calculate DDS. Foods were divided into 5 main groups: grains, vegetables, fruits, meat, and dairy products. The main groups had 23 subgroups. Total DDS divided to 4 quartiles: less than 3.0, 3.0–5.5, 5.6–8.5, and more than 8.5. Anthropometric parameters including: weight, height, waist circumference (WC), and hip circumference were measured. Data were analyzed by Kolmogorov-Smirnov test, χ² test, and analysis of variance (ANOVA) test with SPSS 20 software (IBM Corp., Chicago, IL, USA). The mean ± standard deviation of DDS and body mass index (BMI) were 5.68 ± 1.73 and 25.1 ± 3.42 kg/m², respectively. The average of the waist-to-hip ratio (WHR) in men and women was 0.92 ± 0.04 and 0.86 ± 0.06, respectively. There was statistically significant difference between DDS and self-reported economic status (p < 0.022). No significant difference was observed between DDS and BMI or WC. However, significant negative correlation was observed between DDS and WHR in men (p < 0.019). This study showed that DDS had a negative correlation with the WHR. Therefore, dietary diversity may improve health status by effect on fat distribution in body.

Low indices of overweight and obesity are associated with cardiometabolic diseases among adult Filipinos in a rural community / Journal of the ASEAN Federation of Endocrine Societies

@#<p style="text-align: justify;"><strong>OBJECTIVES:</strong> To determine cut-off levels of body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) for overweight/obesity associated with cardiometabolic diseases (CMDs) among adult Filipinos in a rural community.<br /><strong>METHODOLOGY:</strong> This community-based cross-sectional observational study utilized data from our Phase II of Diabetes Self-Management Education Program in San Juan, Batangas, Philippines. It included 332 Filipino adults with no known illnesses and residing for at least 6 months in the rural communities. Optimal cut-offs were determined by the intersection of sensitivity and specificity curves of having at least 1 or 2 CMDs.<br /><strong>RESULTS:</strong> The study population included 332 participants (72.3% females). Mean BMI, WC and WHR were 23.5 kg/m2, 79.5 cm and 0.87 respectively. Twenty eight percent, 11.1%, 78.3% and 85.8% of the participants have hypertension, diabetes, dyslipidemia, and at least 1 CMD respectively. The optimal cut-off for overweight/obesity and central obesity in males and females are BMI of 24 and 23 kg/m2, WC of 84 and 77 cm, and WHR 0.91 and 0.85 respectively.<br /><strong>CONCLUSION:</strong> Similar to other Asian countries, cut-off levels for overweight, obesity, and central obesity associated with CMDs are lower than the currently recommended cut-offs among Filipino adults in rural communities, particularly for WC in both sexes.</p>

Measures of Abdominal Adiposity and Risk of Stroke: A Dose-Response Meta-analysis of Prospective Studies / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>Waist circumference, waist-to-hip ratio and waist-to-height ratio, which are the indicators or measures of abdominal adiposity, have long been hypothesized to increase the risk of stroke; yet evidence accumulated till date is not conclusive. Here, we conducted a dose-response meta-analysis to summarize evidences of the association between these measures of abdominal adiposity and the risk of stroke.</p><p><b>METHODS</b>PubMed and Web of Science databases were searched from inception to May 2015. Two investigators independently conducted the study selection and data extraction. Dose-response relationships were assessed by the generalized least squares trend estimation, while the summary effect estimates were evaluated by the use of fixed- or random-effect models. Subgroup and sensitivity analyses were performed to assess the potential sources of heterogeneity and the robustness of the pooled estimation. Publication bias of the literature was evaluated using Begg's and Egger's test.</p><p><b>RESULTS</b>Altogether 15 prospective cohort studies were identified in this study. The summary of relative risks (95% confidence intervals) of stroke for the highest versus the lowest categories was 1.28 (1.18-1.40) for waist circumference, 1.32 (1.21-1.44) for waist-to-hip ratio, and 1.49 (1.24-1.78) for waist-to-height ratio. For a 10-cm increase in waist circumference, the relative risk of stroke increased by 10%; for a 0.1-unit increase in waist-to-hip ratio, the relative risk increased by 16%; and for a 0.05-unit increase in waist-to-height ratio, the relative risk increased by 13%. There was evidence of a nonlinear association between waist-to-hip ratio and stroke risk, Pnonlinearity=0.028.</p><p><b>CONCLUSION</b>Findings from our meta-analysis indicated that waist circumference, waist-to-hip ratio, and waist-to-height ratio were positively associated with the risk of stroke, particularly ischemic stroke.</p>

The relationship between visceral obesity and hyperuricemia in adults of Heping District of Tianjin / 天津医药

Objective To analyze the relationship between visceral obesity and hyperuricemia (HUA), and to provide the basis for the further study of obesity and HUA. Methods A total of 1 824 participants came from Tianjin Heping District Health Education Guidance Center in 2014 were selected in this study. The investigation was performed with physical examination and laboratory test for all subjects. Body fat analyzer was used to measure the visceral fat area (VFA). The Logistic regression analysis was used to evaluate the relationship between visceral obesity and HUA. Results The prevalence of HUA in men and women increased gradually with VFA increasing (P<0.05). There was a positive correlation between VFA, waist circumference (WC), waist-to-hip ratio (WHR) and serum uric acid (SUA) level (P<0.05). According to the results of Logistic regression analysis, VFA (OR=1.805,95%CI=1.166-2.794) and WHR (OR=2.108,95%CI=1.061-4.189) were the risk factors of HUA in men. And in women, VFA (OR=1.775,95%CI=1.154-2.732), WC (OR=2.015, 95%CI=1.137- 3.570) and WHR (OR=2.489, 95% CI=1.400- 4.426) were the risk factors of HUA. Conclusion The accumulation of visceral fat will increase the risk of HUA. So it is necessary to strengthen the detection of visceral obesity to prevent the development of HUA.
