Socio-demographic factors, overweight/obesity and nutrients associated with hypertension among rural adults (≥18 years): Findings from National Nutrition Monitoring Bureau survey

Background: Hypertension is the leading cause of death throughout the world. The study was conducted to assess the prevalence, determinants and knowledge & practices about hypertension among rural adults in India. Methods: A community-based cross-sectional study was carried out in 10 major states of India. Information on socio-economic & demographic particulars was collected and anthropometric measurements like height, weight, waist & hip circumference and blood pressure were measured. Foods and nutrient intakes were assessed by 24-h recall method. Analysis was done using SPSS window 22. Results: The prevalence of pre-hypertension was 45.3% (95% CI: 44.6e46.0) and hypertension was 22% (95% CI: 21.5e22.3) (age standardized prevalence; 20.2%) while, overweight/obesity was 22.6% (95% CI: 22.2e23.0) as per Asian cut offs (BMI_x0001_23). The prevalence of hypertension was higher in West Bengal (29.5%) and Kerala (28.9%) and low in Madhya Pradesh and Uttar Pradesh (16e19%). The odds of hypertension was 1.2 times higher among forward communities, businessmen, tobacco users and those consuming alcohol, 2e3 times higher among overweight (CI: 1.87e2.25) and obese (2.65e3.27). The odds of hypertension was 1.2 times higher among those consuming lower tertile of carbohydrates (CI ¼ 1.02e1.41) and zinc (CI ¼ 1.11e1.42). About 76% were aware of hypertension, 21% were old hypertensive & 19% were on treatment. Conclusions: Age standardized prevalence of hypertension was 20% among adults and was associated with age, occupation, overweight/obesity, tobacco and alcohol use, low intake of carbohydrates and zinc. Therefore, increasing awareness and consumption of healthy diet through behavior change communication will help to control hypertension among adults.

Modulação Autonômica Cardíaca é Fator Chave para Pressão Alta em Adolescentes / Cardiac Autonomic Modulation is a Key Factor for High Blood Pressure in Adolescentes

Resumo Fundamento O interesse pela hipertensão em crianças e adolescentes aumentou desde a atualização do sistema de classificação da pressão arterial para comparar com o sistema de classificação dos adultos, alterando a terminologia de "normal alta" para "pré-hipertensão". Objetivo O objetivo deste estudo foi analisar a associação da modulação autonômica cardíaca com os níveis pressóricos dos adolescentes. Métodos 203 adolescentes foram agrupados de acordo com a pressão arterial sistólica (PAS) e a pressão arterial diastólica (PAD). Um grupo foi caracterizado como pré-hipertensão, e o outro como normotenso. Foram coletadas características antropométricas, cardiovasculares e de qualidade do sono. Inicialmente, os dados foram submetidos ao teste de normalidade Kolmogorov-Smirnov . As variáveis quantitativas contínuas foram analisadas por meio do teste T de Student não pareado. Para análise das variáveis categóricas, foi utilizado o teste qui-quadrado. Um modelo de regressão logística foi realizado. O nível de significância estabelecido foi p<0,05. Os dados foram expressos como média ± desvio padrão e intervalo de confiança. O software R foi utilizado para análise dos dados. O tamanho do efeito foi calculado com a fórmula de Cohen. Resultados O grupo pré-hipertensão apresentou aumento da entropia de Shannon e diminuição da variância total. Além disso, no modelo de regressão logística, os adolescentes deste grupo tiveram 1,03 mais chances de ter a entropia de Shannon afetada quando a PAS foi ajustada ao gênero, maturação sexual, tempo escolar, idade, circunferência da cintura e qualidade do sono. Conclusão Nossos dados mostram que a modulação autonômica pode desempenhar um papel importante no desenvolvimento da pressão arterial elevada em adolescentes ao controlar fatores como tempo escolar e qualidade do sono.

Abstract Background The interest regarding hypertension among children and adolescents has increased since the blood pressure rating system was updated to be compared with the adult rating system, changing the terminology from "normal high" to "prehypertension". Objective This study aimed to analyze the association between cardiac autonomic modulation and pressure levels of adolescents. Methods 203 adolescents were grouped according to systolic blood pressure (SBP) and diastolic blood pressure (DBP). One group was characterized as prehypertension, and the other as normotensive. Anthropometric, cardiovascular and sleep quality characteristics were collected. Initially, the data were submitted to the Kolmogorov-Smirnov normality test. Continuous quantitative variables were analyzed using the unpaired Student t-test. For the analysis of categorical variables, a chi-square test was used. A logistic regression model was performed. The level of significance was set at p<0.05. The data were expressed as mean ± standard deviation and confidence interval. The R software was used for data analysis. The effect size was calculated using the Cohen's formula. Results The prehypertension group showed an increase in Shannon entropy and a decrease in total variance. Also, in the logistic regression model, adolescents in this group were 1.03 times more likely to have Shannon entropy's affected when SBP was adjusted for gender, sexual maturation, school time, age, waist circumference, and sleep quality. Conclusion Our data show that autonomic modulation may play an important role in the development of elevated blood pressure in adolescents, when controlling for other factors, such as school time and sleep quality.

Prevalence of hypertension and its risk factors among high school children in Bangalore, India

Background: Hypertension is a prominent health disorder that leads to 12.8% of deaths worldwide. Although predominantly considered a disorder of the adults, the roots of hypertension start from childhood. In the past children usually suffered from secondary hypertension. However, now with increased incidence of obesity, reduced physical activity, unhealthy dietary habits, use of tobacco and alcohol among adolescents there is now an increased prevalence of primary hypertension in this age group. The present study was conducted with the objective of assessing the prevalence of hypertension and its modifiable risk factors in high school children.Methods: The study was conducted among high school students aged 13 to 16 years in urban Bangalore. A self-administered questionnaire was used to assess the lifestyle. Age, sex, height, weight and resting blood pressure were recorded. Odds ratio, Chi square test and logistic regression were used in the analysis.Results: There were 550 students who participated in the study, 300 (54.54%) were males and 250 (45.45%) were females. The prevalence of prehypertension was 21.6% and hypertension was 8.9%. Logistic regression revealed that overweight, obesity, high salt intake, tobacco use, and stress were significantly associated with elevated blood pressure.Conclusions: There is a rise in the prevalence of hypertension among high school students. Changes in lifestyle seem to influence the development of hypertension in this age group. Behaviour change communication should be used to reduce the modifiable risk factors and promote healthy lifestyle among adolescents.

Effect of cheese containing Lactobacillus delbrueckii subsp. Lactis CRL 581 on blood pressure in prehypertensive and stage 1 hypertensive subjects / Efecto de un queso con LactobacillusdelbrueckiisubspLactis CRL 581 sobre la hipertensión arterial en individuos con prehipertensión o estadio 1 de hipertensión arterial

Hypertension is one of the main risk factors for cardiovascular disease. Functional foods containing bioactive peptides have been proposed as a strategy to decrease blood pressure (BP) in subjects under no pharmacological treatment. The aim of this study was to compare the effect of low-sodium, low-fat (LSLF) cheese and LSLF cheese containing Lactobacillus delbrueckii subsp. lactis CRL 581 (LSLF581) on BP in pre-hypertensive and stage 1 hypertensive subjects. Sixty-one pre-hypertensive and stage 1 hypertensive subjects assigned to one of twos (LSLF, n= 29 and LSLF581, n= 32) participated in this 12-month prospective, randomized, double-blind, crossover trial. Twenty-four h ambulatory BP monitoring was performed at the beginning and at the end of each four-week study period. Systolic and diastolic BP decreased in both study groups, but differences between groups were not significant (systolic, -1.78 and -0.2 mmHg; diastolic, -1.54 and -0.42 mmHg in LSLF581 and LSLF, respectively). Although our results could not support a BP lowering effect of LSLF581, small BP reductions could favorably prevent cardiovascular disease development.

La hipertensión arterial es uno de los principales factores de riesgo de enfermedad cardiovascular. Los alimentos funcionales que contienen biopéptidos constituyen una estrategia útil para disminuir la presión arterial (PA) en personas que no están bajo tratamiento farmacológico. El objetivo del estudio fue comparar el efecto de un queso bajo en sodio y bajo en grasas (BSBG) y el mismo queso con Lactobacillus delbrueckii subsp. lactis CRL 581 (BSBG581) sobre la PA en personas con prehipertensión y estadio 1 de hipertensión arterial. Realizamos un estudio prospectivo, randomizado, cruzado y doble ciego durante 12 meses en 61 personas con prehipertensión y estadio 1 de hipertensión arterial, asignadas a dos grupos: BSBG (n= 29) y BSBG581 (n= 32). Se realizó monitoreo ambulatorio de la PA (MAPA) durante 24 h al comienzo y al final de cada etapa del estudio (cuatro semanas). La PA sistólica y diastólica disminuyó en ambos grupos, aunque las diferencias entre grupos no fueron significativas (sistólica, -1.78 y -0.2 mmHg; diastólica -1.54 y -0.42 mmHg en BSBG581 y BSBG respectivamente). Aunque nuestros resultados no pueden confirmar el efecto hipotensor del queso BSBG581, las reducciones moderadas de la PA podrían prevenir el desarrollo de enfermedad cardiovascular.

Pre-operative hypertension and its risk factors: A cross-sectional study among patients admitted for surgery at a tertiary health care facility of Eastern India

Background: Hypertension (HTN) is one of the most common diagnoses in a primary health care setting and it is one of the important and preventable contributors to disease and death. HTN is considered as an additional risk factor in anesthesia and HTN is of special importance to the anesthetist for various reasons. Tracheal intubation, surgical incision, recovery from anesthesia, and post-operative pain can increase blood pressure (BP). Objectives: This study aims to find out the burden of pre-operative HTN and its risk factors among patients who were admitted for surgical procedures at a tertiary health care facility of Durgapur, West Bengal, India. Materials and Methods: After obtaining permission from the Institutional Ethics Committee, an institution based, observational, and cross-sectional study was conducted from January 2019 to February 2019. A pre-tested, semi-structured schedule was used to collect Clinic Social data. Anthropometric measurements and BP were taken as per the world health organization STEP-wise approach to surveillance guidelines. BP was classified as per “The eighth joint national committee (JNC-8) guidelines. Results: Data were collected from 150 study subjects and were analyzed using SPSS, version 20.0 for windows. The frequency of pre-operative HTN and pre-HTN was found to be 38.0% and 32.0% respectively. As per JNC-8, 34.7% had Stage-1 HTN followed by 32.0% and 3.3% who had pre-HTN and Stage-2 HTN, respectively. Increasing age, male gender, smoking, increasing body mass index, dyslipidemia, and Type 2 diabetes mellitus (T2DM) were significantly associated with a higher frequency of HTN. Conclusion: There is a very high prevalence of pre-operative HTN and pre-HTN. Increasing age, male gender, smoking, overweight, obesity, dyslipidemia, and T2DM were significant risk factors for HTN. Routine screening of HTN should be done in surgical ward to see if there are cases of “white coat” HTN.

Prevalence of overweight, obesity and hypertension among school going children in District Kanpur, Uttar Pradesh, India: a longitudinal study

Background: India is undergoing a rapid epidemiological transition with increased urbanization and socio-economic development which has resulted in a dramatic change in lifestyle, consisting of physical inactivity, diet rich in fat, sugar and salt coupled with a high level of mental stress. Obesity is one of the most common diseases worldwide and the prevalence in school aged children appears to be increasing. Thus, the present study was planned to establish an association between body mass index (BMI) with hypertension among 10-16 years children.Methods: Present longitudinal study was conducted on 350 children in private schools of District Kanpur and children 12-16yrs of age have included in the study. BMI for age charts was used to assess the obesity and blood pressure was measured by sphygmomanometer and Blood pressure values were compared to the values given by the update of 1987 task force report of the National high blood pressure Education Programme Co-ordinating Committee and children who were found prehypertensive or hypertensive were followed up after 4 weeks duration.Results: In present study the prevalence of overweight and obesity was found 4%,2% respectively. Prevalence of Pre-hypertension and hypertension was found 1.14%, 2.57% respectively and pre-hypertension and hypertension were found more in overweight and obese participants.Conclusions: Prevalence of pre-hypertension and hypertension is more among overweight and obese children. Overweight and obesity are not only risk factor for hypertension but also other diseases, so health education should regularly give about the obesity and its deleterious effects in later part of life.

Leucocytic DNA Methylation of Interleukin-6 Promoter Reduction in Pre-Hypertensive Young Adults

@#Background: Pre-hypertension is associated with increased risk of cardiovascular disease. Chronic inflammation plays an important role in the pathophysiology of essential hypertension, with epigenetic dysregulation involvement. Nevertheless, the role of DNA methylation in prehypertensive state is unknown. The aim of this study was to investigate the association between DNA methylation level of interleukin-6 (IL-6) promoter in pre-hypertensive (PreHT) and normotensive (NT) young adults. Methods: A total of 80 NT and 80 PreHT healthy subjects aged between 18–45 years were recruited in Kuantan, Pahang, Malaysia using an observational cross-sectional study approach. DNA methylation level of IL-6 promoter in peripheral leukocytes were measured using bisulphite conversion and MethyLight assay. Results: There was no significant difference in age between NT and PreHT (P = 0.655). The mean blood pressure was 110(8)/73(5) mmHg in NT and 125(7)/82(5) mmHg in PreHT subjects. The IL-6 promoter methylation level was significantly lower in PreHT compared to NT subjects (P < 0.001). Conclusion: The current study demonstrates that hypomethylation of IL-6 promoter was associated with pre-hypertension in young adults. Thus, IL-6 methylation could be used as an early indicator for predicting hypertension and related risk of cardiovascular diseases in prehypertensive subjects. Gene expression and longitudinal studies are warranted to examine the methylation effect on IL-6 expression over time

Prevalence and Determinants of Pre-Hypertension among Undergraduate Preclinical Medical Students in Central Malaysia

@#Introduction: Pre-hypertension, a classification of blood pressure ranging from 120–139 mm Hg systolic and/ or 80–89 mm Hg diastolic, has been introduced to identify those high-risk group of developing hypertension to implement early intervention to halt disease progression. This study determines the prevalence of pre-hypertension and its determinants among undergraduate preclinical medical students in Malaysia. Materials & Methods: This was a cross-sectional study conducted among 158 registered second year medical students at one research university in central Malaysia from January to April 2018. Results: The prevalence of pre-hypertension was 20.6% among undergraduate preclinical medical students. The most respondent was female (69.9%), Malay ethnic (50.6%) who had normal body mass index (67.3%), no depression (79.5%), no anxiety (60.3%), no stress (68.6%), low physical activity level (44.9%), never smoked (95.5%), and never consumed alcohol (87.8%). Some respondents had positive family history of hypertension (43.6%) and diabetis mellitus (31.4%). After adjusted for all variables, gender (AOR=14.45, 95% CI 5.58-37.43) and depression status (AOR=6.37, 95% CI 1.29-31.49) were significantly associated with pre-hypertension. Conclusion: The prevalence of pre-hypertension among preclinical medical students was lower compared to other country, predicted by gender and depression status. However, further comprehensive multicentered studies in Malaysia with larger sample size is recommended to get more precise results in identifying determinants for pre-hypertension so that early intervention could be implemented nationwide.

Endothelial dysfunction in young pre-hypertension and its influencing factors / 西安交通大学学报(医学版)

Objective To investigate the endothelial dysfunction in pre-hypertension and its influencing factors.Methods A total of 373 youth were divided as the subjects into hypertension group (HBP group),prehypertension group (PHT group) and normal blood pressure group (NBP group).Endothelial function was assessed based on carotid intima-media thickness (IMT),brachial artery flow-mediated dilation (FMD) and brachial-ankle pulse wave velocity (baPWV).Results IMT and baPWV in PHT group were higher than those in NBP group (P＜0.05),but did not reach the significant difference when compared with HBP group (P＞0.05).Compared with HBP,the levels of FMD in PHT group significantly increased (P＜ 0.05);however,no difference was observed in comparison with NBP group (P＞0.05).In the early stage of hypertension,diastolic BP (β=-0.120,P＜0.05) and body mass index (β=-0.115,P＜0.05) were negatively correlated with FMD;diastolic BP (β=0.146,P＜0.05),2-hour glucose (β=0.147,P＜0.05),high-density lipoprotein cholestrol (β=0.150,P＜0.05),and waist-hip ratio (β=0.126,P＜0.05) showed a positive correlation with IMT.baPWV was correlated with systolicBP (β=0.358,P＜0.01),waist circumference (β=0.254,P＜0.05),fasting glucose (β=0.155,P＜0.05),postprandial 2 h blood glucose (β =0.152,P ＜0.05),uric acid (β =0.206,P ＜ 0.05),and C-reactive protein (β=0.099,P＜0.05).Corclusion Our study shows that endothelial dysfunction may exist in the prehypertensive young,and several cardiovascular risks contribute to its development in the early stage of hypertension.

Prevalence of pre-hypertension and its relationship with body mass index among the medical students of Agartala government medical college.

Background: Body Mass Index (BMI) is found to be positively co-related with the increased prevalence of elevated blood pressure among younger individuals. The present study was designed to find out the prevalence of pre-hypertension and its relationship with BMI among the medical students. Methods: A cross-sectional study was conducted during June - July 2013 among 306 medical students of Agartala government medical college, chosen by stratified random sampling. Results: Prevalence of pre-hypertension, hypertension and optimum BP were found to be 45%, 4% and 51% respectively. Mean BMI was found to be 21.68 ± 3.55, 80% of the students had ideal waist hip ratio, 19% were underweight, 61 % had normal weight, 18 % were overweight, and 2% were found to be obese. Pre-hypertension was significantly more prevalent among the senior medical students (χ2 = 4.933, P = 0.026), males (χ2 = 10.826, P = 0.001) and those who had family history of hypertension (χ2 = 4.228, P = 0.039). Pre-hypertension was significantly higher among the obese medical students (χ2 = 6.941, P = 0.008). Logistic regression analysis revealed that medical students had 12.8% more chance of having pre-hypertension with one unit increase in their BMI. Conclusion: Prevalence of pre-hypertension among medical students is high and BMI is found to be significantly associated with pre-hypertension. Hence it can be used as an effective tool for predicting pre-hypertension and development of hypertension among medicos later on.

The prevalence rate in urban area was 12.4% and in rural was 13.2%, P=0.47, the prevalence in male gender was 12.7% and in female was 12.4%,P=0.81. With the increased age, the prevalence trend was elevated accordingly. Multi-regression analysis indicated that the elder age, overweight or obesity (female with abdominal obesity), sibling history of hypertension, hyper-triglyceridemia, multiple childbirth and menopause had the higher risk of coexisting pre-hypertension and pre-diabetes condition, allP Conclusion: There is a high prevalence rate of coexisting pre-hypertension and pre-diabetes condition in middle to elder population in Chengdu area and the prevalence is closely related to age. It is important to prevent such condition by elevating educational level nationwide, controlling waist and body weight, adjusting diet structure with proper exercise.

hsCRP in pre-hypertension and hypertension: a prospective study in Southern Asian region.

Background: Hypertension is turned into a leading cause of non-communicable disease associated mortality and morbidity in both developing as well as developed world. Hypertension is reported to be the fourth contributor to premature death in developed countries and the seventh in developing countries. In the regard of early diagnosis and better prognosis, the concept of pre-hypertension, defined as a systolic blood pressure of 120-139 mmHg and/or a diastolic blood pressure of 80-89 mmHg was introduced as the new guideline for the management of blood pressure by the seventh report of the Joint National Committee on prevention, detection, evaluation, and treatment of high blood pressure (JNC-7). Among various other factors inflammation may be a causative factor for development of Hypertension But the association is not very clear. Accordingly, we have designed our study to find any association of hsCRP with pre-hypertension and hypertension so that early prevention and control can help to avoid or delay the grave outcome and complications of hypertension. Methods: A total of 37 hypertensives, 30 pre-hypertensives and 31 age and sex matched healthy control subjects were selected for the study, with consent. Two BP readings were taken five minutes apart, on both arms, with a mercury sphygmomanometer. The estimation of serum hsCRP was done on XL-600 automatic analyzer with the kit (Erba Mannheim) based on the measurement of antigen-antibody reaction by the end-point method. Results: There is significant difference in systemic and diastolic blood pressure and hsCRP in between group study. In pre-hypertensive group hsCRP is correlated with diastolic blood pressure. Conclusion: Our results suggest a correlation exists between hsCRP and hypertension more significantly with pre-hypertension. So estimation of serum hsCRP can be a good diagnostic as well as prognostic marker in diagnosing pre-hypertensives and prevent the occurance of hypertension and cardio vascular disorders thereby.

First report on simplified diagnostic criteria for pre-hypertension and hypertension in a national sample of adolescents from the Middle East and North Africa: the CASPIAN-III study / Primeiro relatório sobre critérios de diagnóstico simplificado para pré-hipertensão e hipertensão em uma amostra nacional de adolescentes do Oriente Médio e da África do Norte: o estudo CASPIAN-III

OBJECTIVE: This study aimed to simplify the diagnostic criteria of pre-hypertension (pre-HTN) and hypertension (HTN) in the pediatric age group, and to determine the accuracy of these simple indexes in a nationally-representative sample of Iranian children and adolescents. METHOD: The diagnostic accuracy of the indexes of systolic blood pressure-to-height ratio (SBPHR) and diastolic BPHR (DBPHR) to define pre-HTN and HTN was determined by the area under the curve of the receiver operator characteristic curves. RESULTS: The study population consisted of 5,738 Iranian students (2,875 females) with mean (SD) age of 14.7 (2.4) years. The prevalences of pre-HTN and HTN were 6.9% and 5.6%. The optimal thresholds for defining pre-HTN were 0.73 in males and 0.71 in females for SBPHR, and 0.47 in males and 0.45 in females for DBPHR, respectively. The corresponding figures for HTNwere 0.73, 0.71, 0.48, and 0.46, respectively. In both genders, the accuracies of SBPHR and DBPHR in diagnosing pre-HTN and HTN were approximately 80%. CONCLUSIONS: BPHR is a valid, simple, inexpensive, and accurate tool to diagnose pre-HTN and HTN in adolescents. The optimal thresholds of SBPHR and DBPHR were consistent with the corresponding figures in other populations of children and adolescents with different racial and ethnic backgrounds. Thus, it is suggested that the use of these indexes can be generalized in programs aiming to screen elevated blood pressure in the pediatric age group. .

OBJETIVO: Este estudo visa simplificar os critérios de diagnóstico da pré-hipertensão (pré-HTA) e hipertensão (HTA) na faixa etária pediátrica e determinar a precisão desses índices simple sem uma amostra nacionalmente representativa de crianças e adolescentes iranianos. MÉTODO: A precisão diagnóstica dos índices de relação pressão arterial sistólica/altura (RPASA) e RPAA diastólica (RPADA) para definir a pré-HTA e HTA foi determinada pela área sob as curvas de características de operação do receptor. RESULTADOS: A população estudada contou com 5738 alunos iranianos (2875 meninas) com idade média (DP) de 14,7 (2,4) anos. A prevalência de pré-HTA e HTA foi 6,9% e 5,6%. Os limites ideais para a definição de pré-HTA foram 0,73 em meninos e 0,71 em meninas com relação à RPASA e 0,47 em meninos e 0,45 em meninas com relação à RPADA, respectivamente. Os valores correspondentes com relação à HTA foram 0,73, 0,71, 0,48 e 0,46, respectivamente. Em ambos os gêneros, a precisão de RPASA e RPADA no diagnóstico de pré-HTA e HTA foi de aproximadamente 80%. CONCLUSÕES: A RPAA é uma ferramenta válida, simples, barata e precisa no diagnóstico da pré-HTA e HTA em adolescentes. Os limites ideais de RPASA e RPADA foram compatíveis comos números correspondentes em outra população de crianças e adolescentes com diferentes históricos raciais e étnicos, assim, sugerimos que a utilização desses índices possa ser generalizada em programas de triagem com relação à PA elevada na faixa etária pediátrica. .

Relationship between urinary albumin-to-creatinine ratio and prehypertension among young migrant builders in Shanghai / 第二军医大学学报

Objective To explorethe relationship between urinary albumin-to-creatinine ratio (UACR) and blood pressure of young migrant builders in Shanghai. Methods A total of 3 195 builders (age ranged from 18 to 50) were selected from migrant builders of Shanghai Construction Group Co., Ltd. by using random clustersampling method. They were subjected to questionnaire interview, physical examination, and biochemical tests, including UACR, renal function, serum uric acid, serum lipid, and serum glucose. The participants were divided into 4 groups (I, II, III, and IV) according to the levels of UACR, and the ordinal multinomial logistic regression model was employed todetermine the relationship between UACR levels and blood pressure grouping (normal, pre-hypertension, and hypertension). Results Among the 3 195 builders, 3 112 (97. 4%) finished interview. The UACR (median [Q1-Q3]) levels and high-UACR ratio for the normal, pre-hypertension and hypertension groups were 0. 8 (0. 6-1. 2) mg/mmol, 0. 9 (0.7-1. 4) mg/mmol, and 1. 0 (0.8-1. 7) mg/mmol, and 6. 8%, 8. 0%, and 15. 6 %, respectively, with significant differences for both UACR levels and high-UARC ratios (P<0. 05) among the 3 blood pressure groups. According to the 25%, 50%, and 75% quartiles of UACR values, builders were classified into 4 groups. After adjustment of the other factors such as age, the average systolic pressures of the I, II, III, and IV UACR groups were (126. 8± 13. 3), (127. 9 ± 14. 2), (129.9 ± 14. 4), and(134. 2 ± 19. 0) mmHg (1 mmHg= 0. 133 kPa), and the average diastolic pressures of the 4 groups were (77. 6±9. 7), (78. 8±9. 2), (79. 2 ± 10. 4), and (81. 8 ± 12. 5) mmHg, respectively. UACR was positively correlated with both the average systolic pressures and diastolic pressures (P<0. 05). Logistic regression analysis showed that, after adjusting the factors such as age, body mass index, total cholesterol, and low density lipoprotein cholesterol, the odds ratio (OR) and 95% confidence interval (95% Cl) of pre-hypertension and/or hypertension, compared with I group, were 0. 98 (0. 80-1. 20), 1. 29 (1. 05-1. 58), and 1. 86 (1. 52-2. 28) for II, III, and IV groups, respectively. Conclusion The UACR is positively correlated with pre-hypertension and hypertension among young migrant builders in Shanghai.

Psychological Determinants Of Pre-Hypertension Among First Year Undergraduate Students In A Public University In Malaysia

Pre-hypertension increased the risk of morbidity and mortality from non-communicable diseases. Whereas, psychological factors such as depression, anxiety and stress have been associated with increased in blood pressure. However, previous studies more focuses on psychological determinants of hypertension than prehypertension. Thus, this study aims to determine the association between these psychological factors with pre-hypertension. A cross-sectional study was conducted in 2012 among first year students of a public Malaysian university. A random cluster sampling was used to select 5 out of 15 faculties and a total of 495 students participated in this study. The Malay version of DASS-21 was used to elicit their levels of depression, anxiety and stress. Blood pressures were measured twice using sphygmomanometer and the averages were taken. Data analyses used chi-square test and binary multiple logistic regression. The prevalence of pre-hypertension was 30.1%. The percentage of severe and extremely severe depression was 3.8% and 1.2%; both severe and extremely severe anxiety was 16.4%; and severe and extremely severe stress was 4.2% and 0.2% respectively. Severe/extremely severe depression had more than 3 times higher in getting pre-hypertension than no depression. In conclusions, almost one third of respondents had pre-hypertension and only severe/extremely depression was associated with pre-hypertension.

La pre hipertensión en el vórtice de las enfermedades cardiovasculares / Pre-hypertension in the vortex of the cardiovascular diseases

Introducción: la prehipertensión es la categoría de la tensión arterial definida como una tensión arterial sistólica entre 120 y 139 mm Hg y diastólica entre 85 y 89 mm Hg. La prehipertensión es parte de la evolución natural de la hipertensión, que está surgiendo en los momentos actuales como un factor de riesgo importante para la enfermedad cardiovascular y cerebrovascular. Método: se realizó una búsqueda en las principales web internacionales acerca de prehipertensión y síndrome metabólico hasta comienzos del 2014. Desarrollo: la definición del síndrome cardio-metabólico es un grupo de factores de riesgo vasculares como son: la obesidad abdominal, prehipertensión o hipertensión, dislipidemia y prediabetes o diabetes. En los momentos actuales se recomienda la prevención basada en la intervención en el estilo de vida y también el tratamiento farmacológico de los componentes individuales que así lo ameriten, dado que la mayoría de los pacientes categorizados como síndrome metabólico están en la categoría de alto riesgo. Hay varios estudios basados en cambios dietéticos que mostraron que cambios ayudaron detener la progresión de hipertensión y también mejoraron las condiciones metabólicas. Varios ensayos clínicos están en marcha para estudiar varias drogas antihipertensivas para retardar el desarrollo de hipertensión. Conclusiones: la enfermedad cardiovascular y cerebro vascular precoz ha sido identificada en individuos asintomáticos, lo que sugiere crear guías de terapia preventiva individualizada acorde a la valoración de los factores de riesgo tradicionales.

Background: pre-hypertension is the arterial tension category defined as a systolic arterial tension between 120 and 139 mm Hg and a diastolic one between 85 and 89 mm Hg. Pre-hypertension is part of the hypertension natural evolution, currently emerging as an important risk factor for cardiovascular and cerebrovascular disease. Method: we carried out a search in the main international webs on pre-hypertension and metabolic syndrome up to the beginning of 2014. Development: by definition, the cardio-metabolic syndrome is a group of cardiovascular risk factors such as: abdominal obesity, pre-hypertension or hypertension, dyslipemia and pre-diabetes or diabetes. At the current times, it is recommended prevention based in life style intervention and also the pharmacologic treatment of the individual components deserving it, because most of the patients categorized as metabolic syndrome are in the high risk category. There are several studies based in dietetic changes that showed what changes helped stopping hypertension progression and also improved metabolic conditions. Several clinical trials are in progress for studying some antihypertensive drugs to delay hypertension development. Conclusions: the precocious cardiovascular and cerebrovascular disease has been identified in asymptomatic individuals, suggesting the elaboration of preventive therapy guidelines, individualized according to the traditional risk factors evaluation.

Cardiovascular risk factors in an eastern Caribbean Island: prevalence of non-communicable chronic diseases and associated lifestyle risk factors for cardiovascular morbidity and mortality in the British Virgin Islands / Factores de riesgo cardiovascular en una Isla Del Caribe Oriental: prevalencia de las enfermedades crónicas no comunicables y factores de riesgo asociados con el estilo de vida en relación con la morbilidad y la mortalidad cardiovasculares en las Islas Vírgenes Británicas

BACKGROUND: The epidemiological transition has seen a trend from communicable to non-communicable diseases in developing countries. At the pinnacle of these chronic diseases is hypertension, pre-hypertension, diabetes and obesity. This leads to increased cardiovascular morbidity and mortality worldwide. In addition, environmental and behavioural changes such as lifestyle habits represent modifiable risk factors for the development of cardiovascular diseases. The Caribbean is not immune to this trend. METHODS: This was a cross-sectional survey conducted between June and September 2009 and involved individuals 15 - 74 years of age. Age-gender was weighted to get as close a representative sample of the general population living in the British Virgin Islands (BVI) for more than two years to a total of 301 (n = 301, M: 144, F: 157; CI 95% ± error 5%). The study was carried out using a handout questionnaire that included variables on age, gender, socio-economic status (SES), income level, cigarette smoking, physical activity, weight, height, body mass index (BMI), blood pressure, fasting blood glucose and cholesterol. RESULTS: This study shows a prevalence of hypertension of 16.6%, pre-hypertension - 29.9%, diabetes mellitus - 10.0% [M: 5.6%, F: 14%, p < 0.01], impaired fasting glucose (IFG) - 16.9% [M: 13.9%, F: 19.7%, p < 0.01], overweight - 25.6% (M: 19.4%, F: 31.2%, p < 0.001), obesity (body mass index > 30) - 23.6% (M: 17.4%, F: 29.3%, p < 0.001) [all significantly higher in women], smoking habits - 16.6% and alcohol - 51.2% [significantly higher in men: 22.5% and 56.7%, respectively]. Of the respondents, 43.2% had a low/inactive physical activity level. Clustering of greater than one risk factor was more pronounced for women than for men 29.6% (M: 27.1%, F: 31.8%, p < 0.05). Sedentary lifestyle (low/inactive physical activity) and obesity were the only risk factors that had a positive correlation with all four chronic diseases (p < 0.05). CONCLUSION: The above results indicate that a national strategy needs to be implemented to control cardiovascular diseases, educate the population and promote healthy lifestyle habits with particular attention to low physical inactivity and obesity.

ANTECEDENTES: La transición epidemiológica ha visto una tendencia a pasar de enfermedades comunicables a enfermedades no comunicables en los países en vías de desarrollo. En la cima de estas enfermedades crónicas se hallan la hipertensión, la pre-hipertensión, la diabetes y la obesidad. Esto conduce al aumento de la morbilidad y la mortalidad cardiovasculares a nivel mundial. Además, los cambios medioambientales y conductuales tales como los hábitos de estilo de vida, representan factores de riesgo modificables para el desarrollo de las enfermedades cardiovasculares. El Caribe no es ajeno a esta tendencia. MÉTODOS: Se trata de un estudio transversal llevado a cabo entre junio y septiembre de 2009, el cual incluyó individuos de 15 - 74 años de edad. Se ponderó la edad-género con el propósito de obtener una muestra tan representativa como fuera posible de la población general que vive en las Islas Vírgenes Británicas (IVB) por más de dos años para un total de 301 (n = 301, M: 144, F: 157; CI 95% error ± 5%). El estudio fue llevado a cabo usando hojas informativas con un cuestionario que incluían las variables: edad, género, estatus socioeconómico (ESE), nivel de ingresos, hábito de fumar, actividad física, peso, altura, índice de masa corporal (IMC), presión sanguínea, y prueba de colesterol y de glucosa en sangre en ayunas. RESULTADOS: Este estudio muestra una prevalencia de hipertensión de 16.6%, pre-hipertensión 29.9%, diabetes mellitus 10.0% [M: 5.6%, F: 14%, p < 0.01], glucosa en ayunas alterada (GAA) 16.9% [M: 13.9%, F: 19.7%, p < 0.01], sobrepeso 25.6% (M: 19.4%, F: 31.2%, p < 0.001), obesidad (índice de masa corporal > 30) 23.6% (M: 17.4%, F: 29.3%, p < 0.001) [todos significativamente más altos en las mujeres], hábito de fumar 16.6% y consumo de alcohol 51.2% [significativamente más altos en los hombres 22.5% y 56.7%, respectivamente]. De los encuestados, el 43.2% tenían un nivel de actividad física inactivo/bajo. La existencia de más de un factor de riesgo fue más pronunciada en las mujeres que en los hombres 29.6% (M: 27.1%, F: 31.8%, p < 0.05). El estilo de vida sedentario (actividad física inactiva/baja) y la obesidad fueron los únicos factores de riesgo que tuvieron una correlación positiva con las cuatro enfermedades crónicas (p < 0.05). CONCLUSIÓN: Los resultados enumerados indican que es necesario implementar una estrategia nacional a fin de controlar las enfermedades cardiovasculares, educar, y promover hábitos de estilo de vida saludables con atención particular a la actividad física baja y la obesidad.

Del adolescente prehipertenso al adulto hipertenso. ¿Es posible pronosticar la conversión? / From the prehypertensive adolescent to the hypertensive adult. Is possible to predict the conversion?

Introducción: Existen gran cantidad de factores de riesgo para el desarrollo de hipertensión arterial. En pleno siglo XXI se imponen formas más inteligentes de investigar, teniendo en cuenta lo que debe constituir un objetivo prioritario, es decir, evitar la conversión de un adolescente en riesgo cardiovascular a un adulto hipertenso. Objetivo: Diseñar un modelo de predicción, para pronosticar la conversión de un adolescente prehipertenso en un adulto hipertenso. Métodos: Se estudió una muestra representativa de 125 adolescentes pertenecientes al proyecto "Pesquisaje Escolar en la Adolescencia de Hipertensión Arterial" (PESESCAD-HTA), con diagnóstico de prehipertensión en el año 2001, que fueron seguidos por ocho años (96 meses), hasta enero de 2009. Resultados: Se obtuvo un modelo predictivo, basado en la regresión logística con un índice de exactitud de 70.4%. Conclusiones: La conversión de un adolescente prehipertenso en un adulto hipertenso, se puede vaticinar con una exactitud adecuada.

Introduction: There are many risk factors for developing hypertension. In the XXI century, smarter ways to investigate are needed, so preventing the turning of an adolescent into a hypertensive adult must be a priority. Objective: The aim of this paper is to predict the risk of hypertension onset in adulthood, from cardiovascular tension and risk stratification since adolescence. Methods: A representative sample of 125 adolescents from the project "Pesquisaje Escolar en la Adolescencia de Hipertensión Arterial" (PESESCAD-HTA) was studied. They were diagnosed with prehypertension in 2001, and were followed for eight years (96 months) until January 2009. Results: Two predictive indexes were obtained. The first, based on the total cardiovascular risk and the second from the multiplication of these risks with an accuracy index for each of 61.6% and 70.4%, respectively. Conclusions: The index based on the multiplication of cardiovascular risk can predict, with adequate accuracy, the turning of a prehypertensive adolescent into hypertensive once he/ she reaches adulthood.

Prevalência de pressão arterial elevada em crianças e adolescentes do ensino fundamental / Prevalence of elevated blood pressure in children and adolescents attending highschool / Prevalencia de presión arterial elevada en niños y adolescentes de la enseñanza fundamental

Verificar a prevalência de pressão arterial elevada em crianças e adolescentes e sua associação com indicadores antropométricos. MÉTODOS: Estudo transversal de estudantes de três instituições de ensino em Botucatu (SP). As variáveis avaliadas foram: pressão arterial (PA) (obtida em três ocasiões diferentes), peso, estatura, índice de massa corporal (IMC), circunferência braquial, circunferência abdominal (CA), dobras cutâneas tricipital e subescapular. A PA foi aferida por método auscultatório e classificada em pré-hipertensão (PH) e hipertensão arterial (HAS), para os valores entre os percentis 90 e 95 e maior que o percentil 95, respectivamente. Os dados antropométricos foram comparados, segundo o sexo, pelo teste t de Student. A correlação de Pearson foi utilizada para verificar a variação das PA sistólica (PAS) e diastólica (PAD) segundo dados antropométricos. A variação do escore Z da PA segundo percentil de IMC foi avaliada pela análise de variância seguida do teste de Tukey. RESULTADOS: Foram avaliadas 903 crianças (51,7 por cento meninos), com idade de 9,3±2,5 anos para ambos os sexos. A prevalência de PH foi de 9,1 por cento e de HAS foi de 2,9 por cento. Houve correlação positiva significativa entre os níveis de PAS e PAD elevados e as variáveis antropométricas, com valores maiores para peso (r=0,53 e r=0,45, p<0,05, respectivamente) e CA (r=0,50 e r=0,38, p<0,05, respectivamente). CONCLUSÕES: A prevalência de níveis pressóricos elevados nesta casuística foi compatível com outros estudos brasileiros e internacionais, correlacionando-se positivamente com indicadores antropométricos elevados, o que sinaliza a influência do excesso de peso na PA já na infância.

To assess the prevalence of elevated blood pressure in schoolchildren and adolescents and the association of blood pressure with anthropometric measures. METHODS: This cross-sectional study, conducted in three schools in Botucatu, Brazil, collected blood pressure (BP) measurements taken at three different time points and anthropometric data: weight, height, body mass index (BMI), arm circumference, waist circumference, triceps and subscapular skinfolds. Blood pressure was measured using the auscultation method, and children were classified into two groups: pre-hypertension or hypertension for values between the 90th and 95th percentiles or above the 95th percentile. Data were compared according to sex using the Student's t test. The Pearson correlation coefficient was used to evaluate the association between blood pressure and anthropometric data. To evaluate blood pressure, the Z score according to BMI percentile categories, one-factor analysis of variance (ANOVA) and the Tukey post hoc test were used. RESULTS: This study evaluated 903 children and adolescents (51.7 percent boys) whose mean age was 9.3±2.5 years. The prevalence of pre-hypertension and hypertension was 9.1 percent and 2.9 percent. There was a positive correlation between both systolic and diastolic blood pressure and anthropometric variables, especially for weight (r=0.53 and r=0.45, p<0.05) and waist circumference (r=0.50 and r=0.38, p<0.05). CONCLUSIONS: The prevalence of elevated blood pressure in this study was similar to what has been reported in international and national studies. A positive correlation with abnormal anthropometric measures was found. These results suggest that overweight affects blood pressure already in childhood.
