ABSTRACT
Objective To investigate the predictive value of body mass index (BMI), waist circumference (WC), waist to height ratio (WHtR) and visceral obesity index (VAI) in the prevalence of hypertension in adult residents of Anlu City. Methods A multi-stage stratified random sampling method was used to investigate adult residents in Anlu. T test, χ2 test, Pearson correlation analysis and logistic regression model were used to analyze relationship between the obesity indicators and the prevalence of hypertension. The receiver operating curve (ROC) was used to analyze the predictive power of different obesity indexes for the prevalence of hypertension. Results A total of 2 518 subjects were included in this study, including 705 patients with hypertension, with a prevalence rate of 28.00%. Occupation, marital status, educational level, abnormal blood glucose, dyslipidemia and obesity were the risk factors of hypertension. The correlation coefficients of BMI, WC, WHtR and VAI with systolic blood pressure were 0.32, 0.30, 0.34 and 0.10, respectively, and with diastolic blood pressure were 0.27, 0.26, 0.29 and 0.08, respectively. Logistic regression analysis showed that overweight OR=1.79 (CI: 1.43 - 2.25), obesity 2.94 (CI: 2.04 - 4.24), waist circumference OR=1.86 (CI: 1.43-2.40), waist height ratio OR=2.52 (CI: 1.97-3.20) and higher VAI OR=1.08 (CI: 1.02-1.15) were associated with a higher risk than those with normal weight. The AUCs of the four obesity indicators for predicting the prevalence of hypertension were WHtR (0.74) >BMI (0.70) >WC (0.69) >VAI (0.56), and the difference was statistically significant (P<0.001). Conclusion BMI, WC, WHtR and VAI are positively correlated with hypertension, and WHtR has a higher predictive value for hypertension.
ABSTRACT
Objective To understand the change of plasma lipopolysaccharide(LPS) in Kazakh children with overweight and obesity and to investigate the correlation between LPS and physical measurement indexes .Methods One hundred and four children were selected from 7648 native school age children in Altay area participating in the Epidemiological Investigation of Overweight and Obesity of School Age Children in Xinjiang as the research subjects .The physical measurement indexes such as body weight , height ,waist circumference(WC) ,hip circumference(HP) and blood pressure were measured ,and the body mass index (BMI) and waist to height ratio(WHtR) were calculated .LPS and biochemical indexes such as blood glucose(FPG) and blood lipid were detec-ted .Results With BMI increase ,the indexes including WC ,HP ,systolic blood pressure(SBP) and WHtR were also increased .The serum LPS and TG levels in the obesity group were significantly higher than those in the overweight group and control group .LPS had positive correlation with BMI grade (normal ,overweight and obesity ) ,r=0 .865 ,P= 0 .000 ,and also had positive correlation with WC (r=0 .556 ,P=0 .000) and WHtR(r=0 .477 ,P=0 .000) respectively ;the Kazakh school age chidren with WHtR abnor-mal increase had higher blood pressure and LPS level .WHtR and SBP had a positive correlation(r=0 .441 ,P=0 .000) .Conclusion LPS is correlated with overweight and obesity in Kazakh school age children .The child with abdominal obesity is easier to appear SBP abnormal elevation and LPS level increase .
ABSTRACT
Background: Overweight and obesity are recognized as recent threat which affecting both developing and developed countries. Obesity and its associated morbidities are leading cause of most non-communicable diseases. Few recent studies have indicated the presence of increase in overweight and obesity among children and adolescent but there is no study among adult groups. Method and material: This cross sectional study was done to assess the prevalence of overweight, obesity and metabolic variables with their relation among medical students. Result: Our result reveals that 8.6% & 1.9% male and 15% & 3.2% female are suffering from overweight and obesity (based on BMI) respectively. More females (31.3% and 65.2%) are centrally obese than males (3.5% and 34.8%) (According to Waist Hip ratio and Waist Height ratio respectively). But according to Waist circumference more males (30.7%) are obese than females (24%). There is also significant difference of male and female BP. DBP and SBP of male (79.22mmHg & 118.9 mmHg) have high normal level than female (72.71mmHg and 108.67mmHg) (P<0.001). There is no significant difference of glycaemic status (p<.286) and lipid profile (p<.347) with central obesity. Conclusion: Although male students have high upper level of blood pressure, female students are more obese than males (both according to BMI and central obesity). High blood pressure and obesity both acts as risk factors for the development of non communicable disease. Student’s awareness therefore should be increased to reduce central obesity and BP within normal range.
