Anthropometric indices and its association with hypertension among young medical students

Abstract

Introduction: Obesity, defined on the basis of anthropometric measures is a global epidemic and threatening to healthy population worldwide. A research from China among young adults (20--44 years) recorded six and two times the risk of hypertension (HTN) in individuals who were obese and overweight, respectively, relative to normal weight individuals. This study highlights about anthropometric indices and its association with HTN among young medical students at rural medical college. Methods: In this cross-sectional study, 1,000 medical students had been enrolled. Anthropometric indices like body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), neck circumference (NC) as per South East Asian guidelines were measured in all students. Results: Among young medical students, the prevalence of obesity defined by BMI, WC, WHR, and NC was 46.5%, 32.4%, 57.3%, and 8.4%. Among males, there was significant positive correlation of BMI with SBP ( P < 0.0001) and DBP ( P < 0.0001), whereas WC ( P < 0.0001) and WHR ( P = 0.012) had positive and significant correlation with SBP but not with DBP. Correlation of NC with SBP and DBP was negative but did not reach statistical significance ( P = 0.266 and P = 0.670, respectively). Among females, there was significant positive correlation of BMI with SBP ( P < 0.0001) and DBP ( P < 0.0001), WC had significant positive correlation with SBP ( P < 0.0001,) and DBP ( P < 0.0001). Correlation of WHR was significant with DBP ( P = 0.002) but not with SBP ( P = 0.055). Conclusion: The prevalence of HTN in this study was 9.8% in young medical students overall and varies according to anthropometric indices. The prevalence rate varies in males and females depending on the anthropometric measures.

Association of Asthma With Patients Diagnosed With Metabolic Syndrome: A Cohort Study in a Tertiary Care Hospital

“…The study participants' average type II diabetes prevalence was about 61%, and their average blood pressure was about 83%, demonstrating the relationship between metabolic syndrome and asthma. This was discovered to be comparable to other research that established the relationship between asthma and metabolic problems [11,18]. As previously mentioned, insulin resistance impairs the energy production in the mitochondria, which reduces oxygen supply and causes asthma by increasing bronchial reactivity through inhibition of the presynaptic M2 muscarinic receptor and being linked to skeletal muscle weakness, including the respiratory system.…”

“…Numerous cell types, including vascular endothelial cells, renal epithelial cells, and glandular epithelium, have altered activities in the metabolic syndrome. It is unknown but extremely possible that people with metabolic syndrome have altered airway epithelium or sub-epithelial function [18,19].…”

The Pattern of Blood Pressure Distribution and Analysis of Influencing Factors of Pre (Hypertension) Among Young Adults: A Cross-Sectional Survey in Western India

“…It has been concluded from numerous studies that higher BMI is positively associated with prehypertension and hypertension. 8,21 A meta-analysis by Guo et al reported higher body mass indices among individuals with prehypertension. 22 Similar findings were also observed by Parthaje et al in urban adults of South India.…”
