Background: Previous studies that investigated association of height with prevalence and control of hypertension found mixed results. This cross-sectional study explored these associations among US adults (≥20 years). Methods: The National Health and Nutrition Examination Survey (NHANES) 2007–18 data was analyzed. Height was measured in meters and was converted into centimeters (cm) and was further divided into quartiles: Q1 (135.3–159.2 cm), Q2 (159.3–166.2 cm), Q3 (166.3–173.6 cm), Q4 (173.7–204.5 cm). Hypertension definition of the ‘2017 American College of Cardiology/American Heart Association Guideline’ was used. Logistic regression analyses were conducted to find out the association between the dependent variable and the covariates. Linear regression analyses were conducted to find out the association of height with systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), and the covariates among the individuals who were not taking any antihypertensive drugs. Crude odds ratio, adjusted odds ratio (AOR), and adjusted beta-coefficient (for linear regression) with 95% confidence interval (CI) were reported. The following covariates were included: age, gender, race/ethnicity, family income, education level, cholesterol level, high-density lipoprotein level, chronic kidney disease status, diabetes status, smoker, aerobic leisure-time physical activity, and survey period. Sample weight of NHANES was adjusted. Results: Among the 21,935 participants (47.1% males), the prevalence of hypertension was 46.1%. Among 6154 participants taking medication (43.0% males), 57.2% had uncontrolled hypertension. In the final logistic regression analyses, participants in Q2 height quartile had 20% lower odds of being hypertensive compared to those in Q4 height quartile (AOR: 0.8; 95% CI: 0.7,1.0). Other height categories did not reveal any significant association. Compared to Q4 height category, Q1 (AOR: 1.7; 95% CI: 1.2,2.3), Q2 (AOR: 1.4; 95% CI: 1.1,1.8), and Q3 (AOR: 1.3; 95% CI: 1.1,1.6) height categories had higher odds of uncontrolled hypertension. PP was inversely associated and DBP was positively associated with height Conclusions: Although height was not associated with prevalence of hypertension, it had inverse association with uncontrolled hypertension. It was also significantly associated with DBP and PP among the individuals with untreated hypertension.

Rajat Das Gupta,Shams Shabab Haider,Animesh Talukdar,Mohammad Rifat Haider 질병관리본부 2019 Osong Public Health and Research Persptectives Vol.10 No.6

Objectives: This study aims to determine the prevalence, and associated factors of undiagnosed hypertension [Systolic Diastolic Hypertension (SDH), Isolated Systolic Hypertension (ISH) and Isolated Diastolic Hypertension (IDH)] in the Nepalese adult population. Methods: Nepal Demographic and Health Survey 2016 data from adults (≥ 18 years) was used in this study. The final weighted sample size was 13,393. Blood pressure (BP) was measured 3 times and the average of the second and third measurement was reported. SDH (systolic BP (SBP) ≥ 140 mmHg and diastolic BP (DBP) ≥ 90 mmHg), ISH (SBP ≥ 140 mmHg and DBP < 90 mmHg), and IDH (SBP < 140 mmHg and DBP ≥ 90 mmHg) were measured. Multilevel logistic regression analyses were conducted to find the association between the independent variables and the covariates. Results: The prevalence of SDH, IDH and ISH were 8.1%, 7.5%, and 3.3% respectively. The odds of having SDH and ISH increased with old age. However, the odds of having IDH decreased with increasing age. Females has lower odds of having SDH and IDH compared with male participants. Individuals that had been married, resided in Province 4 (p < 0.05) or 5 (p < 0.01) were statistically significantly associated with having IDH. Being overweight or obese was statistically significantly associated with all 3 HTN subtypes (p < 0.001). Conclusion: The necessary steps should be taken so that public health promotion programs in Nepal may prevent and control undiagnosed hypertension.

RAJAT GUPTA,RIDHAM BAKSHI,Suram Singh,ARUN BHARTI 장전수학회 2021 Proceedings of the Jangjeon mathematical society Vol.24 No.4

A systematic study of nuclear structure properties of proton rich even-even positive parity 80,82,84Se isotopes have been studied within twobody self-consistent quantum mechanical framework known as Projected Shell Model (PSM)which incorporates quadrupole-quadrupole, monopole and quadrupole pairing interactions. The description of band structures of even-even 80,82,84Se nuclei based on the band diagrams indicates the presence of multiquasi-particle structure which provides us a unified understanding of ever accumulating high spin structure of these nuclei. The back-bending in moment of inertia, yrast spectra and g-factor have also been obtained and are also compared with the available experimental data.

Objective This study aimed to determine the association between body mass index (BMI) and abdominal obesity with hypertension among the South Asian adults (18–69 years). Methods This study utilized the nationally representative WHO STEPwise approach to surveillance data (n=24,413) from Afghanistan, Bangladesh, Bhutan, Nepal, and Sri Lanka. Hypertension was defned as having a systolic blood pressure of 140 mmHg or higher, a diastolic blood pressure of 90 mmHg or higher, and/or taking antihypertensive medications. A waist circumference≥90 cm in men and≥80 cm in women was considered as abdominal obesity. BMI was categorized according to Asia-specifc cutof and overweight was defned as BMI of 23.0–27.5 kg/m2 and obesity was defned as BMI≥27.5 kg/m2 . Multivariable logistic regression analyses were conducted to identify the association between BMI and abdominal obesity with hypertension. The odds ratio (OR) with a 95% confdence interval (CI) was reported. Results Abdominal obesity increased the odds of hypertension 31%-105% compared to those who did not have abdominal obesity (OR: Afghanistan: 2.05; 95% CI: 1.27–3.31; Bangladesh: 1.55; 95% CI: 1.18–2.04; Bhutan: 1.31; 95% CI: 1.03–1.66; Nepal: 1.69; 95% CI: 1.31–2.18; Sri Lanka:1.55; 95% CI: 1.23–1.95). The odds increased among participants with both overweight/obesity and abdominal obesity. In all fve countries under study, participants with both overweight and abdominal obesity (OR: Afghanistan: 2.75; 95% CI: 1.75–4.34; Bangladesh: 2.53; 95% CI: 1.90–3.37; Bhutan: 2.22; 95% CI: 1.64–3.00; Nepal: 2.08; 95% CI: 1.54–2.81; Sri Lanka: 2.29; 95% CI: 1.77–2.98), as well as those with obesity and abdominal obesity (OR: Afghanistan: 6.94; 95% CI: 4.68–10.30; Bangladesh: 2.95; 95% CI: 2.19–3.97; Bhutan: 3.02; 95% CI: 2.23–4.09; Nepal: 4.40; 95% CI: 3.05–6.34; Sri Lanka: 3.96; 95% CI: 2.94–5.32), exhibited higher odds of having hypertension as compared to participants with a normal BMI and no abdominal obesity. Conclusion Having both abdominal obesity and overweight/obesity increased the odds of hypertension among South Asian adults. Preventing overweight/obesity and abdominal obesity is necessary for preventing the burden of hypertension in South Asia.

Critical Review of Flexible Pavement Performance Models

Ankit Gupta,Praveen Kumar,Rajat Rastogi 대한토목학회 2014 KSCE JOURNAL OF CIVIL ENGINEERING Vol.18 No.1

Maintenance and repair of the highway network system are major expenses in the state budget. For this reason various concerned organizations are pointing out the need for developing an intelligent and efficient pavement performance model that can prioritize pavement maintenance and rehabilitation works. Such models can forecast the remaining pavement service life and pavement rehabilitation needs, and can help in the formulation of pavement maintenance and strengthening programmes which will reduce the road agency and road user costs. The flexible pavement performance or deterioration models involve the complex interaction between vehicles and the environment, and the structure and surface of the pavement. Performance models relating to the pavement distress conditions like, cracking, raveling, potholing, and roughness are analyzed and developed by various researchers. But most of these models are found applicable to a particular set of traffic or environment conditions, thus highlighting the need of model(s) that can work in varied conditions satisfactorily. The paper presents a detailed review of various pavement performance models to examine the role of factors related to pavement materials, environmental conditions, type of traffic and volume of traffic, and to identify the limitations and gaps in the present knowledge on such models.

Al Kibria Gulam Muhammed,Gupta Rajat Das,Jannatun Nayeem 대한고혈압학회 2021 Clinical Hypertension Vol.27 No.4

Background: The prevalence of hypertension is increasing in Bangladesh, however, few recent studies investigated the proportion of people and factors associated with prevalence, awareness, and control of this condition in this country. This study investigated these among Bangladeshi adults. Methods: Using Bangladesh Demographic and Health Survey 2017–18 data, a cross-sectional study was conducted. Multilevel logistic regression analysis was employed after descriptive analysis and prevalence estimation. Results: Among 12,926 persons (mean age: 40 years, 57% women), the prevalence of hypertension was 27.4% (n = 3551), it was 28.4 and 26.2% among females and males, respectively. Among hypertensive people, about 42.4% (n = 1508) people were aware of having it, 48.7% among females and 33.5% among males. Of the 1313 people who were taking antihypertensive medication, only 33.8% (n = 443) had controlled hypertension, 34.7 and 31.7% among females and males, respectively. Among the studied factors associated with hypertension, people with older age, female gender, overweight/ obesity, diabetes, richer wealth quintiles, and residence in some administrative divisions had higher odds of hypertension (p < 0.05). However, the odds of awareness was lower among younger people, males, and people without overweight/obesity, diabetes, or richer wealth quintiles. Odds of controlled hypertension was also lower among people with older age and higher among college-educated people. Conclusion: This study identified several important factors associated with prevalence, awareness, and control of hypertension. It is important to address these factors with nationwide prevention and control programs.

Investigations of H-Darrieus rotors for different blade parameters at low wind speeds

Anal R. Sengupta,Agnimitra Biswas,Rajat Gupta 한국풍공학회 2017 Wind and Structures, An International Journal (WAS Vol.25 No.6

Studies of unsymmetrical blade H-Darrieus rotors at low wind speeds in terms of starting time, static torque, and power performances for different blade parameters: thickness-to-chord (t/c), camber position, and solidity are scarce. However these are required for knowing insights of rotor performances to obtain some design guidelines for the selection of these rotors. Here, an attempt is made to quantify the effects of these blade parameters on the performances of three different H-Darrieus rotors at various low wind streams. Different blade profiles, namely S815, EN0005 (both unsymmetrical), and NACA 0018 (symmetrical blade for comparison) are considered. The rotors are investigated rigorously in a centrifugal blower apparatus. Firstly the dynamic and static performances of the rotors are evaluated to determine the best performing rotor and their optimum solidity. Generalised performance equations are developed based on selected blade parameters which are validated for the unsymmetrical rotors. Further, the starting time is quantified with respect to the rotor inertia to determine the suitable range of inertia that helps the unsymmetrical blade rotor to self-start earlier than the symmetrical one. This study can work as a benchmark for the selection of optimum blade parameters while designing an unsymmetrical blade rotor at low wind speeds.
