Abstract BackgroundObesity has become a global epidemic and an important risk factor for non-communicable diseases. Earlier thought to be a problem of developed world, it has now become a problem of low- and middle-income countries like Nepal. In absence of a routine surveillance or a registry system, the actual burden and trend of obesity in Nepal is unknown. Obesity and overweight are recognized risk factors for hypertension and associated with cardiovascular disease. The aim of the study was to find out burden of obesity, using three commonly employed metrics in hospital outpatient setting of a low-income country as predictors of hypertension, and compare ability of different anthropometric measurements through a non-inferiority study to predict hypertension.MethodsThis cross-sectional study was conducted among 40-69 years outpatients in a tertiary Eye and ENT hospital in a semi-urban area of Nepal among randomly selected 2,256 participants from 6,769 outpatients who were evaluated in Health Promotion and risk factor screening service. We did correlation analysis to determine the relationship between anthropometric measurement and blood pressure. The area under the Receiver Operating characteristic curve of Body Mass Index (BMI), Waist to Height Ratio (WHtR) and Waist Circumference (WC) was calculated and compared. ResultsThe prevalence of obesity and overweight by BMI was 16.09% and 42.20% respectively; by Waist-to-Height-Ratio was 32.76% which is two times higher than obesity measured by BMI. High waist circumference was observed among 66.76% participants. Female participants had greater prevalence of high WC (77.46%) than male (53.73%) (p<0.001). Prevalence of hypertension and pre-hypertension was 40.67% and 36.77% respectively. The areas under the curve were significantly higher than 0.5 for BMI (0.593), WHtR (0.602) and WC (0.610).ConclusionWaist circumference correlated well with obesity and hypertension. It also had higher predicting ability than WHtR and BMI to predict hypertension. Waist circumference thus proved to be non-inferior to two other commonly used metrics. It proved superior in detecting obesity in female. This simple and inexpensive tape measurement may play an important role in future diagnosis of obesity and prediction of HTN in resource constrained settings of developing countries.

ObjectivesTo demonstrate the accuracy and flexibility of using waist-to-height ratio (WHtR) as a screening tool for identifying children and adolescents with cardiometabolic risk (CMR) across a wide range of prevalence levels among general paediatric populations.DesignA nationwide population-based cross-sectional study with all data collected at school settings in six cities of China.ParticipantsA total of 8130 children and adolescents aged 7–18 years with complete anthropometric and CMR measurements based on blood tests were recruited.Outcome measuresElevated blood pressure, dyslipidaemia, elevated fasting blood glucose and central obesity were measured. The primary outcome, CMRs, was defined as meeting three or more of the above risk factors. The accuracy of WHtR for identifying CMRs was evaluated using areas under the curves (AUCs) with 95% CI of the receiver operating characteristic curve. The predictability of WHtR at given CMRs prevalence levels was estimated by positive predictive value (PPV) and negative predictive value.ResultsOverall, 6.1% of study participants were presented with CMRs. WHtR had high AUCs ranging from 0.84 (95% CI 0.81 to 0.88) to 0.88 (95% CI 0.86 to 0.90) in the total population and age-subgroup and gender-subgroup. The overall optimal WHtR cut-off value was 0.467, with boys having a higher cut-off than girls (0.481 vs 0.456). WHtR achieved an overall sensitivity of 0.89 and PPV of 18.8% at a specificity of 0.75. The screening performance of WHtR remained satisfactory across a wide range of given CMRs prevalence levels (5%, 10% and 20%).ConclusionWHtR as a screening tool could accurately and flexibly identify children affected with the clusters of three or more of CMR factors from the general paediatric population with various CMR prevalence levels. Our findings provide support for policy-making on early CMR identification and management in the high-risk group of children.

This cross-sectional study was conducted to determine the predictive power of anthropometric indicators and recommend cutoff points to discriminate hypertension among adolescents in Sarawak, Malaysia. A total of 2461 respondents aged 12-17 years participated in this study with mean age of 14.5±1.50 years. All anthropometric indicators had significant area under the ROC curve, with body mass index (BMI) and waist circumference (WC) ranging from 0.7 to 0.8. The best anthropometric indicators for predicting hypertension for boys were WC, BMI, and waist-to-height ratio (WHtR). For girls, BMI was the best indicators followed by WHtR and WC. The recommended BMI cutoff point for boys was 20 kg/m2 and 20.7 kg/m2 for girls. For WC, the recommended cutoff point was 67.1 cm for boys and 68.2 cm for girls. BMI and WC indicators were recommended to be used at the school setting where the measurement can easily be conducted.

Abstract Background: Inappropriate sleep duration (shorter/longer than optimal sleep duration) has come to be identified as a potential cardiometabolic risk factor, and thereby, as a risk factor for atherosclerotic cardiovascular disease (ASCVD). Few data exist regarding the gender differences in the relationship between sleep duration and cardiometabolic risk.Methods: This cross-sectional study was conducted in a study population of 9262 apparently healthy (5004 male, 4258 female) subjects at the Health Planning Center of Nihon University Hospital between September, 2015, and October 2016.Results: In the male subjects, as compared to a sleep duration of 6 to 7 hours, a sleep duration of ³8 hours was associated with an odds ratio (OR) for abdominal obesity (defined according to the Japanese criteria for metabolic syndrome as a waist circumference of ³85 cm) of 1.31 (95% confidence interval [CI], 1.004-1.71) and for a non-high-density lipoprotein cholesterol level of ³150 mg/dL (defined as “Borderline hyper” by the Japan Atherosclerosis Society Guidelines for Prevention of ASCVD 2017) of 1.33 (1.05-1.68), and a sleep duration of <5 hours was associated with an OR (95% CI) for a fasting blood glucose of ³100 mg/dL (defined as “high” by a specialized lifestyle checkup program for the detection of symptoms of metabolic syndrome in Japan) of 1.74 (1.25-2.42). On the other hand, in the female subjects, as compared to a sleep duration of 6 to 7 hours, a sleep duration of <5 hours was associated with an OR (95% CI) for abdominal obesity (waist circumference ³90 cm) of 1.98 (1.11-3.55) and for a hemoglobin A1c (HbA1c) level of ³5.6 % of 1.52 (1.10-2.10), whereas a sleep duration of ³8 hours was not associated with worsening of any of the examined cardiometabolic risk factors. Conclusions: There may be gender differences in the relationship between sleep duration and cardiometabolic risk. To further reduce the risk of ASCVD, it may be of particular importance to emphasize adequate sleep duration.Clinical Trial Registration: UMIN (http://www.umin.ac.jp/) Study ID:　 UMIN000037643 retrospectively registered on 9 August 2019

The Relationship

Aim. To investigate the relationship between high blood pressure (HBP) and obesity in Egyptian adolescents.Methods. A cross-sectional study of 1500 adolescents (11–19 years) in Alexandria, Egypt, was conducted. Resting BP was measured and measurements were categorized using the 2004 fourth report on blood pressure screening recommendations. Additional measures included height, weight, and waist and hip circumferences. Obesity was determined based on BMI, waist circumference (WC) and waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR) indicators. Crude and adjusted odds ratios were used as measures of association between BP and obesity.Results. Prevalence rates of prehypertension and hypertension were 5.7% and 4.0%, respectively. Obesity was seen in 34.6%, 16.1%, 4.5%, and 16.7% according to BMI, WHR, WC, and WHtR, respectively. Adjusting for confounders, HBP was significantly associated with overall obesity based on BMI (OR=2.18, 95%,CI=1.38-3.44) and central obesity based on WC(OR=3.14, 95%,CI=1.67-5.94).Conclusion. Both overall obesity and central obesity were significant predictors of HBP in Egyptian adolescents.
