Abstract
Introduction Cardiovascular disease (CVD) prevalence in Kenya is rising. Overweight, pre-hypertension and physical inactivity at younger ages is contributory. These risk factors are inadequately documented among Kenyan children and adolescents, hampering CVD prevention. Methods this cross-sectional study randomly sampled 384 participants from Eldoret, Kenya. After ethical considerations, physical activity was assessed. Body mass index (BMI), Waist-Hip-Ratio (WHR) and Waist-Height-Ratio (WHtR) were determined, and blood pressure (BP) was measured. Results participants were 14.6±2.7 years, and 62.6% were female. Eight percent had BMI ≥25.0 kg/m2. Of these, 87% were in secondary schools. Using SBP, 27.9% had CVD risk (42.5% and 20% for males and females ≥13 years and 26.5% and 27% for those <13 years, respectively). For DBP, 12.8% had elevated-to-hypertensive BP (13.2% and 8.3% for males and females ≥13 years and 11.8% and 25.4% for those <13 years, respectively). Combining SBP and DBP, 8.1%, mostly males, had elevated-to-hypertensive BP. Using respective WHR cutoffs of 0.90 and 0.85, 31% (boys) and 15.6% (girls) were at CVD risk. For WHtR, 39.6% of boys were >0.463 cut-off (0.493±0.02) against 32.4% for girls >0.469 cut-off (0.517±0.05). Of these, 52.6% (boys) and 69.7% (girls) were in secondary schools. Overall, 45% of participants were sports-inactive and 77.2% did minimal physical activities. Conclusion among school-going children and adolescents in Eldoret, Kenya, the prevalence of CVD risk factors was high, especially among boys and in high schools. Large proportions had elevated BP, BMI, WHR and WHtR, and, further, were sedentary, posing a high CVD risk. Lifestyle interventions to mitigate this are urgently needed.

Vo HK, Nguyen DV, Vu TT, Tran HB, Nguyen HTT. Prevalence and risk factors of prehypertension/hypertension among freshman students from the Vietnam National University: a cross-sectional study. BMC Public Health 2023; 23:1166. [PMID: 37328903 PMCID: PMC10276403 DOI: 10.1186/s12889-023-16118-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2023] [Accepted: 06/13/2023] [Indexed: 06/18/2023] Open
Abstract
BACKGROUND Prehypertension (PHT) and hypertension (HTN) in young adults are essential risk factors for other cardiovascular diseases (CVD) in later years of life. However, there is a lack of knowledge about the burden and risk factors of PHT/HTN for Vietnamese youth. The aim of this study was to investigate the prevalence of PHT/HTN and risk factors among university students in Hanoi, Vietnam. METHODS This study was designed as a cross-sectional investigation with 840 students (394 males and 446 females) randomly sampled from freshmen of Vietnam National University, Hanoi (VNU). Socio-demographic, anthropometric, and lifestyle data were collected using questionnaire forms and physical measurements. HTN was defined as blood pressure (BP) ≥ 140/90 mmHg and/or current treatment with antihypertensive medications. PHT was defined as a systolic BP from 120 to 139 mmHg and/or a diastolic BP from 80 to 89 mmHg. Body mass index (BMI) was classified according to the WHO diagnostic criteria for Asian adults: normal weight (BMI 18.5-22.9 kg/m2), underweight (BMI < 18.5 kg/m2), overweight (BMI 23-24.9 kg/m2), and obese (BMI ≥ 25 kg/m2). Bivariable and multivariable log-binomial regression analyses were conducted to explore the association of PHT/HTN with different risk factors. RESULTS The overall prevalence of prehypertension and hypertension was 33.5% [95% CI: 30.3-36.8%] (54.1% in men and 15.3% in women) and 1.4% [95% CI: 0.7-2.5%] (2.5% in men and 0.5% in women), respectively. Regarding CVD major risk factors, 119 (14.2%) were identified as overweight/obese, 461 (54.9%) were physical inactivity, 29.4% of men and 8.1% of women reported consuming alcohol. The multivariable analysis indicated the male sex (adjusted prevalence ratio [aPR] = 3.07; 95% CI: 2.32-4.06), alcohol consumption (aPR = 1.28; 95% CI: 1.03-1.59) and obesity (aPR = 1.35; 95% CI: 1.08-1.68) as the independent risk factors for PHT/HTN. CONCLUSIONS The results revealed the high burden of prehypertension and hypertension among university freshmen in VNU. Male sex, alcohol consumption, and obesity were identified as important risk factors for PHT/HTN. Our study suggests an early screening program for PHT/HTN and campaigns to promote a healthy lifestyle for young adults in Vietnam.

Abstract
BACKGROUND The prevalence of obesity-related co-morbidities is rising parallel to the childhood obesity epidemic. High blood pressure (BP), as one of these co-morbidities, is detected nowadays at increasingly younger ages. The diagnosis of elevated BP and hypertension, especially in the childhood population, presents a challenge to clinicians. The added value of ambulatory blood pressure measurement (ABPM) in relation to office blood pressure (OBP) measurements in obese children is unclear. Furthermore, it is unknown how many overweight and obese children have an abnormal ABPM pattern. In this study we evaluated ABPM patterns in a population of overweight and obese children and adolescents, and compared these patterns with regular OBP measurements. METHODS In this cross-sectional study in overweight or obese children and adolescents aged 4-17 years who were referred to secondary pediatric obesity care in a large general hospital in The Netherlands, OBP was measured during a regular outpatient clinic visit. Additionally, all participants underwent a 24-hour ABPM on a regular week-day. Outcome measures were OBP, mean ambulatory SBP and DBP, BP load (percentage of readings above the ambulatory 95th blood pressure percentiles), ambulatory BP pattern (normal BP, white-coat hypertension, elevated BP, masked hypertension, ambulatory hypertension), and BP dipping. RESULTS We included 82 children aged 4-17 years. They had a mean BMI Z-score of 3.3 (standard deviation 0.6). Using ABPM, 54.9% of the children were normotensive (95% confidence interval 44.1-65.2), 26.8% had elevated BP, 9.8% ambulatory hypertension, 3.7% masked hypertension, and 4.9% white-coat hypertension. An isolated night-time BP load > 25% was detected in almost a quarter of the children. 40% of the participants lacked physiologic nocturnal systolic BP dipping. In the group of children with normal OBP, 22.2% turned out to have either elevated BP or masked hypertension on ABPM. CONCLUSIONS In this study a high prevalence of abnormal ABPM patterns in overweight or obese children and adolescents was detected. Additionally, OBP poorly correlated with the child's actual ABPM pattern. Herewith, we emphasized the usefulness of ABPM as an important diagnostic tool in this population.

Abstract
There is an increasing prevalence of obesity among college/university students in low- and middle-income countries, similar to the trend observed in high-income countries. This study aimed to describe the trend and burden of overweight/obesity and emerging associated chronic disease risks among students at the University of Ibadan (UI), Nigeria. This is a ten-year retrospective review of medical records of students (undergraduate and post-graduate) admitted between 2009 and 2018 at UI. Records of 60,168 participants were analysed. The Body Mass Index (BMI) categories were determined according to WHO standard definitions, and blood pressure was classified according to the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC7). The mean age of the participants was 24.8, SD 8.4 years. The majority were ≤ 40 years (95.1%). There was a slight male preponderance (51.5%) with a male-to-female ratio of 1.1:1; undergraduate students constituted 51.9%. The prevalence of underweight, overweight, and obesity were 10.5%, 18.7% and 7.2%, respectively. We found a significant association between overweight/obesity and older age, being female and undergoing postgraduate study (p = 0.001). Furthermore, females had a higher burden of coexisting abnormal BMI characterised by underweight (11.7%), overweight (20.2%) and obese (10.4%). Hypertension was the most prevalent obesity-associated non-communicable disease in the study population, with a prevalence of 8.1%. Also, a third of the study population (35.1%) had prehypertension. Hypertension was significantly associated with older age, male sex, overweight/obesity and family history of hypertension (p = 0.001). This study identified a higher prevalence of overweight and obesity than underweight among the participants, a double burden of malnutrition and the emergence of non-communicable disease risks with potential lifelong implications on their health and the healthcare system. To address these issues, cost-effective interventions are urgently needed at secondary and tertiary-level educational institutions.

Abstract
In Ghana, the management of hypertension in primary health care is a cost-effective way of addressing premature deaths from vascular disorders that include hypertension. There is little or no evidence of large-scale studies on the prevalence, risk, and knowledge/awareness of hypertension in students aged 12-22 years in Ghana. In a cross-sectional study, blood pressure, anthropometric indices, and knowledge/awareness assessment of students at second-cycle schools were recorded from 2018 to 2020 in three regions of Ghana. Multistage cluster sampling was used in selecting regions and the schools. Prevalence of prehypertension and hypertension was categorized by the Joint National Committee 7, where appropriate, chi-square, scatter plots, and correlations were used in showing associations. A total of 3165 students comprising 1776 (56.1%) females and 1389 (43.9%) males participated in this study within three regions of Ghana. The minimum age was 12 years and the maximum age was 22 years. The mean age was 17.21 with standard deviation (SD: 1.59) years. A 95% confidence interval was set for estimations and a P value < 0.05 was set as significant. The prevalence rate of overall hypertension was 19.91% and elevated (prehypertension) was 26.07%. Risk indicators such as weight, BMI, waist circumference, physical activity, and form of the diet were positively correlated with hypertension. Among Ghanaian students currently in second-cycle educational institutions, 19.91% were hypertensive and 26.07% were prehypertensive. This may indicate a probable high prevalence of hypertension in the future adult population if measures are not taken to curb the associated risks.

Abstract
BACKGROUND Studies examining the association between levels of serum uric acid (SUA) and risk of prehypertension still remained controversial conclusions. Also, a quantitative assessment of the dose-response association between them has not been reported. We aimed to quantitatively evaluate risk of prehypertension with levels of SUA based on observational study. METHODS We searched the PubMed, Embase, and Web of Science databases up to December 3, 2019 for relevant studies. Pooled relative risks (RRs) and 95% confidence intervals (CIs) were calculated using random-effects models. The possible linear or non-linear SUA-prehypertension association was modelled by restricted cubic splines. RESULTS We included 17 articles (17 studies) with a total of 79,358 participants and 34,591 cases of prehypertension. Compared with lowest levels of SUA, risk of prehypertension increased 46% (RR 1.46, 95% CI 1.28-1.66) for highest levels of SUA. For per 1 mg/dL increment in levels of SUA, risk of prehypertension increased by 12% (RR 1.12, 95% CI 1.08-1.17). Also, we found evidence of a linear SUA-prehypertension association (Pnon-linearity=.368). CONCLUSION Elevated levels of SUA may be associated with increased risk of prehypertension. Present findings provide the evidence that lowering levels of SUA should be suggested in order to reduce the risk of prehypertension. More longitudinal and intervention studies are needed to clarify the optimal protective levels and whether reducing levels of SUA could prevent or control prehypertension and the progression of prehypertension to hypertension.

Abstract
Background. Hypertension (HTN) is the second main source of outpatient morbidity in Ghana, and the understanding of a disease is necessary for its prevention and management. Language and communication are contributing factors to HTN in Ghana. No studies have been conducted to assess knowledge/awareness of HTN (in the context of its understanding) among students in Ghana. Following a local name for HTN in Ghana, researchers interviewed students through a focus group to assess their understanding/perception (meaning, cause, and prevention) of the disease. Available literature has concerned itself with clients' knowledge of their condition (diagnosis) rather than their comprehension of the true nature of what HTN is. The objective of this study is to assess the knowledge/awareness of HTN in the context of its understanding of the meaning, perception, causes, and prevention of hypertension among students of Ghana's Senior High School (Second Cycle). Semistructured interviews with the use of the theme lists were employed. Focus group conversations and interviews were held in the local Akan (Twi) language, which was later translated, interpreted, and analyzed. Overall, 25 second-cycle students participated. 60% were between 15 and 17 years, 24% were ≥18 years, and 16% were <15 years of age. Males were 44% and females were 56%. Students gave diverse perceptions of their knowledge of HTN. The local language's translation of HTN has influenced and affected its meaning/understanding among some, thus affecting their perception of causes and prevention.

Abstract
OBJECTIVES To assess factors associated with prehypertension and hypertension among children in North Africa. METHODS An epidemiological observational, school- and college-based study among 3562 healthy children and adolescents to assess factors associated with blood pressure categories (normal, prehypertensive, hypertensive), including perinatal (gestational age, birth weight, breastfeeding) and current lifestyle characteristics (body mass index, time spent watching a screen and time spent exercising). RESULTS Prevalence of hypertension increased with age from 8.7% between 6-10 years to 14.7% between 11-15 years, and 15.6% above 15 years. Prevalence of prehypertension and hypertension increased with body mass index from 9.9% and 11.5% among children not overweight to 15.6% (RR 1.58, 95% CI 1.24-2.02, P<0.001) and 17.2% (RR 1.50, 95% CI 1.22-1.85, P<0.001) among those overweight and to 26.8% (RR 2.72, 95% CI 2.04-3.64, P<0.01) and 32.3% (RR 2.82, 95% CI 2.27-3.50, P<0.01) among obese children. There was a trend of association of prehypertension with the time spent watching Television, internet and electronic games. Children whose mother or father had a history of hypertension had a trend to be prehypertensive or hypertensive. A parental hypertension was found in 33.6% of normotensive, 38.2% of prehypertensive, and 42.6% of hypertensive children (P=0.05). Children with prehypertension or hypertension were more likely to have a diabetic father or mother (22.8% and 22.6% vs 15.8%, respectively, P=0.01). Also, prehypertension and hypertension were associated with shorter gestational age, early birth, reduced birth weight, and shorter breastfeeding. CONCLUSION Prehypertension and hypertension have a high prevalence among children in North Africa. They are associated with overweight, obesity, diabetes, a shorter gestational age, a lower birth weight and a shorter breastfeeding.

Abstract
BACKGROUND Although it is not reflected in the OBP measurement in obese children, ambulatory BP changes are known to occur. MH, non-dipper pattern and nocturnal hypertension have been reported to increase in obese children. On the other hand, the factors that indicate a high risk of hypertension are still unclear. The aim of our study is to especially detect masked hypertension by 24-hour BP measurement in obese adolescents and to evaluate the relationship of masked hypertension with metabolic syndrome parameters, anthropometric measurements and hepatosteatosis in these patients. METHODS A total of 63 adolescents diagnosed with obesity were evaluated between January 2019 and December 2019. Office blood pressure was measured for all children, and all of them underwent ABPM. Patients with and without hypertension in ABPM were compared in terms of clinical and laboratory findings. RESULTS The mean age was 14.0 ± 1.7 years, females composed 49.2% of the study population. Office blood pressure measurement revealed hypertension in 4 (6.3%) patients and prehypertension in 15 (23.8%) patients. Thirteen patients (20.9%) were diagnosed with masked hypertension, white coat hypertension was diagnosed in 3 (4.7%) patients. Abnormal ABPM patterns were found to be significantly more frequent in patients with severely obesity (with obesity: 26.4% vs severe obesity: 55.6%, p = 0.03) and patients with a higher waist circumference and waist circumference/height ratio. CONCLUSION The prevalence of masked hypertension in obese adolescents has been found to be quite high. Therefore, we recommend ABPM in adolescents with high waist circumference/height ratio and severe obesity, even if their office blood pressure measurements are normal.

Abstract
BACKGROUND Childhood obesity is a major health concern worldwide. This study examined prevalence trends in severe obesity and related comorbidities among patients referred to a tertiary pediatric obesity clinic in Israel. METHODS The medical files of patients aged 2-18 years with BMI >95th percentile at initial referral to our obesity clinic in 2008-2017 were reviewed for demographic, anthropometric, and cardiometabolic data. Findings were compared between patients with 2.3 > BMI-SDS ≥1.645 and BMI-SDS ≥2.33 (severe obesity), and yearly rates of severe obesity were calculated. RESULTS The cohort included 1,027 children (median age 10.8 years, 41.8% male) of whom 55% were severely obese. The rate of severe obesity among referrals increased from 54% in 2008 to 69% in 2017, but it seemed to plateau during the last 3 years. In between-group comparison, the severe obesity group had a significantly greater predominance of males (p = 0.002), younger age at obesity onset in males (p <0.001), higher rate of a family history of obesity (overall and in males; p = 0.002 and p = 0.01, respectively), and higher rates of obesity-related comorbidities (systolic hypertension, dyslipidemia, obstructive sleep apnea, and nonalcoholic fatty liver disease; p < 0.001). CONCLUSIONS Our data show an increased prevalence of severe obesity over the last decade among Israeli children and adolescents referred to an obesity clinic. This finding may reflect the trend in the general pediatric population or a change in the policy of referral to obesity clinics of pediatricians. The high rate of obesity-related comorbidities emphasizes the importance of early intervention to prevent their devastating consequences, especially in patients with severe obesity.

Cho H, Kim JH. Secular trends in hypertension and elevated blood pressure among Korean children and adolescents in the Korea National Health and Nutrition Examination Survey 2007-2015. J Clin Hypertens (Greenwich) 2020; 22:590-597. [PMID: 32175671 DOI: 10.1111/jch.13842] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Revised: 02/20/2020] [Accepted: 02/24/2020] [Indexed: 02/02/2023]
Abstract
The prevalence of elevated blood pressure (BP) among US children and adolescents has reportedly declined over the past decade. As no Korean data have been analyzed, we aimed to determine recent trends in BP levels among Korean children and adolescents. This study examines data from the Korea National Health and Nutrition Examination Survey segregated into 3 time periods (2007-2009, 2010-2012, and 2013-2015). A total of 7804 Korean children and adolescents aged 10-18 years were included in the analysis. Hypertension (≥95th percentile) and elevated BP (>90th percentile) were defined using the sex-, age-, and height-specific BP standards from 2017 American Academy of Pediatrics guidelines. Mean systolic BP from 2007-2009 to 2013-2015 increased by 3.9 mm Hg, and there was no significant change in diastolic BP. Body mass index (BMI) z-scores significantly increased in the total population from 2007-2009 to 2013-2015. In 2013-2015, the prevalence rates of elevated BP and hypertension were 8.8% and 9.0%, respectively. The prevalence of hypertension in 2013-2015 increased in the total population compared with those in 2007-2009, especially in the obese subgroup, in which the hypertension prevalence was 27.7% in 2013-2015. The prevalence of elevated BP increased during these time period. Associated factors were sex, age, BMI z-score, and survey period for elevated BP; and sex, age, and BMI z-score for hypertension. During our study, mean systolic BP increased, and the prevalence of hypertension in 2013-2015 increased in the pediatric population. A possible influencing factor is obesity, and further long-term data are necessary.

Antioxidants (Basel) 2020; 9:antiox9020096. [PMID: 31979210 PMCID: PMC7071046 DOI: 10.3390/antiox9020096] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2019] [Revised: 01/08/2020] [Accepted: 01/19/2020] [Indexed: 12/28/2022] Open
Abstract
This study investigated the effects of (–)-epicatechin (Epi) in young male borderline hypertensive rats (BHR) during two weeks of treatment (Epi group, 100 mg/kg/day p.o.) and two weeks post treatment (PE group). Epi reduced blood pressure (BP), which persisted for two weeks post treatment. This was associated with delayed reduction of anxiety-like behaviour. Epi significantly increased nitric oxide synthase (NOS) activities in the aorta and left heart ventricle (LHV) vs. the age-matched controls without affecting the brainstem and frontal neocortex. Furthermore, Epi significantly reduced the superoxide production in the aorta and relative content of iron-containing compounds in blood. Two weeks post treatment, the NOS activities and superoxide productions in the heart and aorta did not differ from the age-matched controls. The gene expressions of the NOSs (nNOS, iNOS, eNOS), nuclear factor erythroid 2-related factor 2 (Nrf2), and peroxisome proliferator-activated receptor-γ (PPAR-γ) remained unaltered in the aorta and LHV of the Epi and PE groups. In conclusion, while Epi-induced a decrease of the rats’ BP persisted for two weeks post treatment, continuous Epi treatments seem to be necessary for maintaining elevated NO production as well as redox balance in the heart and aorta without changes in the NOSs, Nrf2, and PPAR-γ gene expressions.

Prevalence of high blood pressure and associated factors among adolescents and young people in Tanzania and Uganda. J Clin Hypertens (Greenwich) 2019; 21:470-478.

Abstract
We conducted a cross-sectional study among school/college students in Tanzania and Uganda to determine the prevalence of high blood pressure (BP) and associated factors. Participants were classified to have high BP if they had pre-hypertension or hypertension. Interviews were done using the WHO STEPS instrument. Using data from both countries (n = 1596), the overall prevalence of high BP was 40% (95% CI: 37-42). The prevalence of pre-hypertension was 29% (95% CI: 26-31) and that of hypertension was 11% (95% CI: 10-13). High BP was independently associated with obesity (aOR = 6.7, 95% CI: 2.2-20.0), male sex (aOR = 3.2, 95% CI: 2.4-4.4), and among males aged above 20 years (aOR = 5.5, 95% CI: 2.9-10.5). Consumption of fruits/vegetables was associated with decreased odds for high BP (aOR = 0.7, 95% CI: 0.50-0.98). The increasing burden of pre-hypertension across age groups could explain the early onset of hypertension and cardiovascular diseases (CVDs) among young African adults. There is a need for longitudinal studies to explore the drivers of pre-hypertension in East African adolescents.

Association of Blood Pressure with Blood Lead and Cadmium Levels in Korean Adolescents: Analysis of Data from the 2010-2016 Korean National Health and Nutrition Examination Survey. J Korean Med Sci 2018; 33:e278.

Abstract
BACKGROUND We evaluated the association of blood pressure (BP) with blood levels of cadmium, lead, and cadmium and lead together (cadmium + lead) in a representative sample of adolescents from Korea. METHODS We used 2010-2016 data from the Korean National Health and Nutrition Examination Survey. This cross-sectional study enrolled adolescents aged at 10-18 years-old who completed a health examination survey and had blood measurements of lead and cadmium. The association of adjusted mean differences in diastolic and systolic BP with doubling of blood lead and cadmium were estimated by regression of BP against log2-transformed blood metals and their quartiles after covariate adjustment. Adjusted odds ratio for prehypertension were calculated for log2-transformed blood levels of lead and cadmium and their quartiles. RESULTS Our analysis of adolescents in Korea indicated that blood levels of lead and cadmium were not significantly associated with increased BP or risk of prehypertension. However, the cadmium + lead level was associated with prehypertension. Previous studies showed that blood levels of lead and cadmium were associated with increased BP and risk of hypertension in adult populations. We found no such association in Korean adolescents. CONCLUSION We found that the cadmium + lead level was associated with prehypertension. The differences between adults and adolescents are because adolescents generally have lower levels of these blood metals or because adolescents only rarely have hypertension.

Abstract
BACKGROUND Severe obesity is rising among adolescents, but data on the prevalence of metabolic abnormalities among this group are limited. We assessed the secular trend of severe obesity and its association with major cardio-metabolic morbidities. METHODS A total of 2,785,227 Israeli adolescents (aged 17.2 ± 0.5 years) who underwent a pre-recruitment medical examination including routine measurements of weight, height and blood pressure between 1967 and 2015 were included. In all, 230,639 adolescents with abnormally excessive BMI were classified into overweight, classes I, II, and III (severe) obesity. Logistic regression was applied to determine the association between BMI groups and prehypertension, high blood pressure and type 2 diabetes (T2DM). RESULTS There was 45-fold increase in the prevalence of class III obesity during study period. Severe obesity was recorded in 2060 males and 1149 females, in whom nearly 35 and 43% had prehypertension or high blood pressure, respectively. Compared with adolescents with overweight, the odds ratios (ORs) for high blood pressure in classes II and III obesity groups, respectively, were 2.13 (95% CI, 2.04-2.23) and 2.86 (2.60-3.15) in males, and 2.59 (2.43-2.76) and 3.44 (3.04-3.90) in females, whereas the ORs for T2DM were 19.1 (12.3-29.6) and 38.0 (22.6-64.0) in males, and 15.1 (11.4-20.0) and 24.8 (17.2-35.7) in females. Results persisted in extensive sensitivity analyses including a longitudinal follow-up (median: males, 3.4 years; females, 4.9 years). CONCLUSIONS Severe obesity showed a marked secular increase and was associated with significantly higher risk for abnormal blood pressure and T2DM than lower degrees of obesity, in both males and females.

Abstract
INTRODUCTION Elevated blood pressure is becoming increasingly common in the pediatric population. Hypertension costs nearly $51 billion/year, and cardiovascular disease is responsible for 17% of the nation's health care expenditures. Traditionally, time-consuming and complicated interpretation standards result in infrequent pediatric blood pressure screenings. This may lead to the under-diagnosis of pediatric hypertension. Early detection of elevated blood pressure is important in order to prevent hypertension related conditions such as, target organ damage, left ventricular hypertrophy, and cerebrovascular disease. The aim of this study was to observe the prevalence of pediatric hypertension among children and adolescents age 3-18 using the smartphone application Pedia BP®. The purpose of this study was to (1) identify the prevalence of elevated blood pressure in a sample of children and adolescents and (2) evaluate any association between BMI, age, and blood pressure classification. METHOD A quantitative, descriptive study was conducted to evaluate the prevalence of pediatric hypertension in 81 preschool and school age children. App users were trained with the online take2heart course available at take2heart.com. The manual systolic and diastolic blood pressure readings were entered into the application, along with the patient's gender, age, height, and weight. Pedia BP® instantly calculated the blood pressure classification of the patient based on percentiles. Quantitative data from the Pedia BP® data repository were analyzed using descriptive statistics. RESULTS We found that 54.3% of our sample were normotensive, 23.5% had prehypertension, 13.6% had stage 1 hypertension, and 8.6% had stage 2 hypertension. As seen in Figure 3, the majority of subjects with stage 1 (72.7%) and stage 2 hypertension (57.1%) were found in school-age children. We found that 3.7% of children were underweight, 48.1% were at a healthy weight, 21% were overweight, and 27.2% were obese. DISCUSSION Pedia BP® was shown to be an effective screening tool to easily classify blood pressure readings on an individual basis. The prevalence of hypertension in our sample was higher than previously reported in the literature. Annual evaluation of blood pressures in preschool and school age children are warranted to identify and address hypertension. Pedia BP® was shown to be an effective screening tool to easily classify blood pressure readings on an individual basis. Pedia BP® offers benefits not only for patients, but for primary care providers, nurses, economists, insurance companies, hospitals, and clinics. Ultimately, Pedia BP® (1) increases awareness of elevated blood pressures among children and adolescents, (2) engages the health care community to screen for elevated blood pressures, (3) implements innovative technology, and (4) activates the potential for a population-based surveillance tool.

Abstract
BACKGROUND Renovascular hypertension (RVH) accounts for 5-10% of pediatric hypertension, and can be associated with underlying disease involving other organs. The purpose of this study was to evaluate the clinical characteristics and assess the treatment outcomes of Korean pediatric patients with RVH. METHODS The medical records of 25 Korean pediatric patients with RVH were retrospectively reviewed. RESULTS Twenty-four patients had underlying disease, and the most common cause was moyamoya disease (MMD; n = 10; 40%). Of 10 patients with MMD, seven had RVH prior to MMD. All patients required antihypertensive medication as the initial treatment and 22 patients subsequently underwent percutaneous transluminal angioplasty (PTA). The majority of patients with MMD had ostial lesions on angiography. Eight patients had favorable outcomes after the first PTA. One patient received nephrectomy, and two patients received bypass surgery because of restenosis after PTA and technical failure of PTA, respectively. During follow up, blood pressure was well-controlled in nine patients, but only four patients were able to discontinue medication. Eight patients had target-organ damage of the brain, heart, and retina at the time of initial diagnosis, and five patients developed chronic kidney disease during follow up. CONCLUSION The most common cause of RVH in Korean children is MMD, and RVH caused by MMD with an ostial lesion is associated with poor PTA outcomes. Angioplasty alone does not appear to control blood pressure effectively in MMD patients, and combined treatment is necessary to prevent target organ damage.

Abstract
Background Although several studies have identified risk factors for high blood pressure (BP), data from Afro-Caribbean populations are limited. Additionally, less is known about how putative risk factors operate in young adults and how social factors influence the risk of high BP. In this study, we estimated the relative risk for elevated BP or hypertension (EBP/HTN), defined as BP ≥ 120/80 mmHg, among young adults with putative cardiovascular disease (CVD) risk factors in Jamaica and evaluated whether relative risks differed by sex. Methods Data from 898 young adults, 18–20 years old, were analysed. BP was measured with a mercury sphygmomanometer after participants had been seated for 5 min. Anthropometric measurements were obtained, and glucose, lipids and insulin measured from a fasting venous blood sample. Data on socioeconomic status (SES) were obtained via questionnaire. CVD risk factor status was defined using standard cut-points or the upper quintile of the distribution where the numbers meeting standard cut-points were small. Relative risks were estimated using odds ratios (OR) from logistic regression models. Results Prevalence of EBP/HTN was 30% among males and 13% among females (p < 0.001 for sex difference). There was evidence for sex interaction in the relationship between EBP/HTN and some of risk factors (obesity and household possessions), therefore we report sex-specific analyses. In multivariable logistic regression models, factors independently associated with EBP/HTN among men were obesity (OR 8.48, 95% CI [2.64–27.2], p < 0.001), and high glucose (OR 2.01, CI [1.20–3.37], p = 0.008), while high HOMA-IR did not achieve statistical significance (OR 2.08, CI [0.94–4.58], p = 0.069). In similar models for women, high triglycerides (OR 1.98, CI [1.03–3.81], p = 0.040) and high HOMA-IR (OR 2.07, CI [1.03–4.12], p = 0.039) were positively associated with EBP/HTN. Lower SES was also associated with higher odds for EBP/HTN (OR 4.63, CI [1.31–16.4], p = 0.017, for moderate vs. high household possessions; OR 2.61, CI [0.70–9.77], p = 0.154 for low vs. high household possessions). Alcohol consumption was associated with lower odds of EBP/HTN among females only; OR 0.41 (CI [0.18–0.90], p = 0.026) for drinking <1 time per week vs. never drinkers, and OR 0.28 (CI [0.11–0.76], p = 0.012) for drinking ≥3 times per week vs. never drinkers. Physical activity was inversely associated with EBP/HTN in both males and females. Conclusion Factors associated with EBP/HTN among Jamaican young adults include obesity, high glucose, high triglycerides and high HOMA-IR, with some significant differences by sex. Among women lower SES was positively associated with EBP/HTN, while moderate alcohol consumption was associated lower odds of EBP/HTN.

[PMID: 29439488 PMCID: PMC5858384 DOI: 10.3390/ijerph15020315] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/28/2017] [Revised: 02/05/2018] [Accepted: 02/08/2018] [Indexed: 12/25/2022]
Abstract
A cross-sectional study was designed to understand the impacts of "hikikomori" lifestyle on physical health. A total of 104 eligible hikikomori cases were recruited from the social services network of Hong Kong with a mean age of 19.02 ± 3.62 (ranged 13-31) year-old, and had completed the set of questionnaires and a series of anthropometric and physical health measurements. Despite SF36 score of 84.0 indicated good physical functioning in general, participants were lived sedentarily with high incidence of hypertension at 15.4% and prehypertension at 31.7%. Occurrence of hypertension and prehypertension in cases living as hikikomori >6 months were 3 times and 1.5 times higher than those newly onset cases, respectively. The blood pressure levels were correlated with age and all obesity index parameters measured including waist circumference and body mass index. Results also observed a shift of body weight from underweight to overweight and obesity along the hikikomori duration. Half of the hypertensive cases involved the elevation of systolic blood pressure, which suggested higher odds of cardiovascular complications. In conclusion, the hikikomori lifestyle could be a risk behavior that may harm the younger generation physically by promoting obesity and hypertension and probably other chronic illnesses.

Abstract
Background Existing evidence suggests that the cardiovascular morbidities are increasing among pre-hypertensive individuals compared to normal. The aim of this study was to evaluate the prevalence of prehypertension, hypertension and to identify psychosocial risk factors for prehypertension among university students in Association of South East Asian Nation (ASEAN) countries. Methods Based on a cross-sectional survey, the total sample included 4649 undergraduate university students (females = 65.3%; mean age 20.5, SD = 2.9, age range of 18–30 years) from 7 ASEAN countries (Indonesia, Laos, Malaysia, Myanmar, Philippines, Thailand and Vietnam). Blood pressure, anthropometric, health behaviour and psychosocial variables were measured. Results Overall, 19.0% of the undergraduate university students across ASEAN countries had prehypertension, 6.7% hypertension and 74.2% were normotensives. There was country variation in prehypertension prevalence, ranging from 11.3% in Indonesia and 11.5% in Malaysia to above 18% in Laos, Myanmar and Thailand. In multivariate analysis, sociodemographic variables (male gender, living in an upper middle income country, and living on campus or off campus on their own), nutrition and weight variables (not being underweight and obese, having once or more times soft drinks in a day and never or rarely having chocolate or candy), heavy drinking and having depressive symptoms were associated with prehypertension. Conclusion The study found a high prevalence of prehypertension in ASEAN university students. Several psychosocial risk factors including male gender, obesity, soft drinks consumption, heavy drinking and depression symptoms have been identified which can help in intervention programmes.

Abstract
There is evidence to show an association between inflammation, obesity and elevated blood pressure. However, there is limited data for this relationship in adolescent females. We aimed to investigate the association between high sensitivity C-reactive protein (hs-CRP) and elevated blood pressure in young Australian females. Women aged 16-25 years living in Victoria were randomly recruited via targeted Facebook advertising. Socio-demographic information was collected via a web-based questionnaire. Anthropometric and blood pressure measurements were conducted by trained staff. Hs-CRP was assessed using the Abbott Architect assay. The demographic data were collected from 639 females (mean ±s.d. age: 22±3). The blood pressure data were available for 502 participants. Approximately 28% had elevated blood pressure (defined by a blood pressure reading ⩾120-139/80-89 mm Hg for adults and >90th and <95th percentiles for age, sex and height for adolescents). Approximately 24% had hs-CRP >3.0 mg l-1 and 30% were overweight or obese. In multivariable logistic regression analyses, obese females (OR: 5.5, 95% CI: 2.4-12.5, P<0.001) were more likely to have elevated blood pressure compared with those with a body mass index (BMI) in the normal range. Elevated hs-CRP levels were associated with an increased odds of elevated blood pressure (OR: 3.4, 95% CI: 1.8-6.3, P<0.001). However, this association was no longer significant after adjustment for BMI. Findings from this study demonstrate that hs-CRP and obesity are associated with elevated blood pressure in young females. Thus, our findings may promote further research into the underlying mechanisms of these associations and related long-term health risks.

Abstract
Background It is not yet clear if blood pressure and renal function changes evolve differently in children with a congenital or acquired solitary functioning kidney. This study aims to assess if there are any differences between these two types of solitary kidney patients. Methods Current research is a retrospective study assessing the evolution of glomerular filtration rate, proteinuria, and blood pressure in clinical records of 55 children with a solitary functioning kidney (37 congenital and 18 acquired). We used the medical records of children who had been assisted, in our unit of pediatric nephrology, for a period of 14 years (168 months), from the time of diagnosis, between January/1997 and December/2015. Results During the study period, glomerular filtration rate (T0 128.89 ± 32.24 vs T14 118.51 ± 34.45 ml/min/1.73 m2, p NS) and proteinuria (T0 85.14 ± 83.13 vs T14 159.03 ± 234.66 mg/m2/die, p NS) demonstrated no significant change. However, after 14 years of follow-up 76.4% of patients had increased levels of arterial hypertension with values over the 90th percentile for gender, age, and height. Specifically, children with an acquired solitary functioning kidney mainly developed hypertension [T0 2/17 (12%) vs T14 9/17 (52.9%) p < 0.025], whereas children with a congenital solitary functioning kidney mainly developed pre-hypertension [T0 3/38 (7.9%) vs T14 17/38 (44.7%) p < 0.0005]. Conclusions The renal function of children with solitary functioning kidneys remains stable during a follow-up of 14 years. However, these children should be carefully monitored for their tendency to develop arterial blood pressure greater than the 90th percentile for gender, age, and height.

Abstract
Primary hypertension among children and adolescents is increasing in prevalence and has been associated with the sequela of left ventricular hypertrophy (LVH), defined by increased left ventricular mass index (LVMI). The association between high blood pressure (BP) and LVMI in an otherwise healthy pediatric population is not well understood. We evaluated the relationship between measures of BP and LVMI in a group of healthy adolescents. We conducted a retrospective review of 55 high school athletes who participated in a community health screen, which included collecting BP readings and limited echocardiograms. End points included prevalence of BP in the ranges of hypertension and prehypertension, prevalence of LVH, and relationship between BP indices and LVMI. No individuals were found to be in the hypertensive range, and there were 13 (24%) in the prehypertensive range. Only one (2%) adolescent met LVH criteria. In multivariable regression analysis, increasing systolic BP index was the only variable significantly associated with greater LVMI (P=0.028). In a healthy cohort of lean adolescents, BP in the prehypertensive range was common in the community health screen setting. Increasing systolic BP index was significantly associated with LVMI.

Abstract
The purpose of this study was to assess the prevalence of abnormal blood pressure in a population of school children during a 3-year follow-up period and its relationship with obesity. Anthropometric and blood pressure data were collected from a population of Italian school children during three consecutive years. During each year blood pressure measurements were repeated three times, at intervals of 1 week. A total of 564 school-children [311 boys; mean (SD) age 8.8 ± 1.4 years] were recruited. During each year, systolic and diastolic blood pressure decreased from visit 1 to visit 3 (p < 0.001). This was associated with a decline in the percentage of prehypertension/hypertension from visit 1 to visit 3. An abnormal blood pressure value in at least one study visit was found in 8.8-17 % of children, whereas the prevalence of hypertension at all three study visits was between 5.2 and 7.8 %, and that of prehypertension at all three visits was between 2.8 and 3.8 %. High blood pressure was more frequent in obese children. In this population of school children the percentage of prehypertension/hypertension remarkably varied when based on one versus three annual assessments, thus emphasizing the importance of repeated measurement before making a diagnosis of abnormal blood pressure. Adiposity was confirmed to be a determinant of high blood pressure.

Abstract
BACKGROUND Cardiovascular disease (CVD) is a public health concern worldwide. Hypertensive heart disease is predominant in Nigeria. To effectively reduce CVD in Nigeria, the prevalence of, and factors associated with, pre-hypertension in Nigerian youth first need to be established. METHODS A locally-validated CVD risk factor survey was completed by 15-18 year olds in a rural setting in south-west Nigeria. Body Mass Index (BMI), waist-hip ratio and systolic and diastolic blood pressure was measured. Putative risk factors were tested in gender-specific hypothesized causal pathways for overweight/obesity, and for pre-hypertension. RESULTS Of 1079 participants, prevalence of systolic pre-hypertension was 33.2 %, diastolic pre-hypertension prevalence approximated 5 %, and hypertension occurred in less than 10 % sample. There were no gender differences in prevalence of pre- hypertension, and significant predictors of systolic pre-hypertension (high BMI and older age) were identified. Considering high BMI, older age was a risk for both genders, whilst fried food preference was female-only risk, and low breakfast cereal intake was a male-only risk. CONCLUSION Rural Nigerian adolescents are at-risk of future CVD because of lifestyle factors, and high prevalence of systolic pre-hypertension. Relevant interventions can now be proposed to reduce BMI and thus ameliorate future rural adult Nigerian CVD.

Abstract
Aims and Objectives To assess the prevalence of cardiovascular disease risk among urban public school students through a collaborative school district and university partnership. Methods Children and adolescents in grades K-12 from 24 urban public schools participated in measurements of height, weight, and other health metrics during the 2009–2010 school year. Body mass index (BMI) percentiles and z-scores were computed for 4673 students. President’s Challenge 1-mile endurance run was completed by 1075 students ages 9–19 years. Maximal oxygen consumption (⩒O2max) was predicted using an age-, sex-, and BMI-specific formula to determine health-related fitness. Resting blood pressure (BP) was assessed in 1467 students. Regression analyses were used to compare BMI z-scores, fitness, and age- and sex-specific BP percentiles across grade levels. Chi-square tests were used to explore the effect of sex and grade-level on health-related outcomes. Results Based on BMI, 19.8% were categorized as overweight and 24.4% were obese. Included in the obese category were 454 students (9.7% of sample) classified with severe obesity. Using FITNESSGRAM criteria, 50.2% of students did not achieve the Healthy Fitness Zone (HFZ); the proportion of students in the Needs Improvement categories increased from elementary to middle school to high school. Male students demonstrated higher fitness than female students, with 61.4% of boys and only 35.4% of girls meeting HFZ standards. Elevated BP was observed among 24% of 1467 students assessed. Systolic and diastolic BP z-scores revealed low correlation with BMI z-scores. Conclusions A community-university collaboration identified obesity, severe obesity, overweight, and low aerobic fitness to be common risk factors among urban public school students.

Abstract
PURPOSE We aimed to evaluate the long-term outcome and efficacy of percutaneous transluminal renal angioplasty (PTRA) for pediatric renal artery stenosis (RAS), which is an important cause of medication-refractory pediatric hypertension. MATERIALS AND METHODS We retrospectively evaluated 22 hypertensive children (age range, 3-17 years) who underwent PTRA from February 2000 to July 2012. Sixteen patients had Takayasu arteritis and six fibromuscular dysplasia. Five were not included in the statistical analysis due to loss to follow-up. RESULTS Technical success was achieved in 32 of 34 procedures (94.1%). The stenosis rate decreased from 84.5% before PTRA to 20.1% after PTRA. Treatment was effective in 72.7% (16/22) of patients, including complete cure in 27.3% (6/22) and improvement in 45.5% (10/22). Systolic and diastolic blood pressures decreased from 153 ± 19.1 to 131.7 ± 21.4 mmHg and from 97.9 ± 14.2 to 83.6 ± 19.3 mmHg, respectively (P <0.01). Number of antihypertensive agents decreased from 2.7 to 0.5 per patient. Restenosis was detected in 40.9% (9/22) of patients, with a restenotic interval of 11.8 months (range, 3-47 months). Lesion length was strongly correlated with clinical success (cure and improvement) (independent-sample t test, P <0.001; binary logistic regression, P = 0.040). CONCLUSION Lesion length is an important determination of clinical success with PTRA for pediatric RAS. PTRA is an appropriate treatment option for pediatric renovascular hypertension due to Takayasu arteritis and fibromuscular dysplasia.

Abstract
There is growing concern about elevated blood pressure in children and adolescents, because of its association with the obesity epidemic. Moreover, cardiovascular function and blood pressure level are determined in childhood and track into adulthood. Primary hypertension in childhood is defined by persistent blood pressure values ≥ the 95th percentile and without a secondary cause. Preventable risk factors for elevated blood pressure in childhood are overweight, dietary habits, salt intake, sedentary lifestyle, poor sleep quality and passive smoking, whereas non-preventable risk factors include race, gender, genetic background, low birth weight, prematurity, and socioeconomic inequalities. Several different pathways are implicated in the development of primary hypertension, including obesity, insulin resistance, activation of the sympathetic nervous system, alterations in sodium homeostasis, renin-angiotensin system and altered vascular function. Prevention of adult cardiovascular disease should begin in childhood by regularly screening for high blood pressure, counseling for healthy lifestyle and avoiding preventable risk factors.

Abstract
Background The present study was designed to evaluate association of psychosocial distress with cardio metabolic risk factors and liver enzymes in Iranian children and adolescents. Method This nationwide study was conducted as the third survey of the school-based surveillance system that was conducted among 5593 school students, 10–18 years in Iran. High triglyceride (TG), high fasting blood sugar (FBS), high total cholesterol (TC), high low-density lipoprotein cholesterol (LDL-C), low high-density lipoprotein cholesterol (HDL-C), hypertension (HTN), generalized obesity and abdominal obesity were considered as cardio metabolic risk factors and alanine transaminase (ALT) and aspartate aminotransferase (AST) were considered as liver enzymes. Data were analyzed using multiple logistic regression (MLR) analysis. Result Psychosocial distress was detected in2027 (71.2%) of boys and 1759 (63.3%) of girls. Among boys, the mean of LDL, AST and DBP were higher and the mean FBS and HDL were lowering those with psychiatric distress than their other counterparts. Girls with psychosocial distress had significantly higher mean of HDL and FBS than those without psychiatric distress. Psychosocial distress significantly increased the odds of high LDL (OR = 2.36, 95%CI 1.53, 3.64), high FBS (OR = 1.23, 95%CI 1.02, 1.49) and low HDL (OR = 1.65, 95%CI 1.41, 1.95). Conclusion Psychosocial distress in adolescents is associated with increased risk of some cardio metabolic risk factors.

Abstract
Since the report from the national high blood pressure (BP) education program working group on BP in children and adolescents and the introduction of a new description called prehypertension many data have been provided on its rate of progression to hypertension, its prevalence and association with other cardiovascular (CV) risk factors and its therapy. Making a diagnosis of prehypertension in a child or adolescent identifies an individual at increased risk for early-onset CV disease who requires specific treatment. Thus, routine BP measurement is highly recommended at every health-care encounter beginning at 3 years of age. This review will present updated data on prehypertension in children and adolescents to increase awareness of health-care providers to the seriousness of this condition. Optimal BP measurement techniques as well as the evaluation and management of prehypertension will be discussed and preventive strategies to reduce the CV risk will be presented.

Abstract
Over the last two decades, essential hypertension has become common in adolescents, yet remains under-diagnosed in absence of symptoms. Diagnosis is based on normative percentiles that factor in age, sex and height. Evaluation is more similar to adult essential hypertension than childhood secondary hypertension. Modifiable risk factors such as obesity, sodium consumption and low exercise should be addressed first. Many anti-hypertensive medications now have specific regulatory approval for children. Sports participation need not be limited in mild or well-controlled cases. Primary care physicians play an important role in reduction of cardiovascular mortality by early detection and referral when needed.

Abstract
BACKGROUND Prehypertension is a new category of blood pressure, and is considered a cardiovascular risk factor. The aim of this study was to estimate the prevalence of prehypertension and its associated factors in young adults in the Philippines. METHODS Undergraduate university students from all areas of study in the University of the Philippines-Visayas were invited to participate. Prehypertension was defined as systolic blood pressure between 120 and 139 mm Hg and/or diastolic blood pressure between 80 and 89 mm Hg. Blood pressure, anthropometric, health behavior, and psychosocial stress variables were measured. RESULTS A total of 754 university students were included in the analysis (mean age, 18.3 ± 1.4 years, 74.3% women). Prehypertension prevalence was 13.9% (36.1% in men, 6.8% in women), and hypertension prevalence was 2.4% (6.6% in men, 1.1% in women). The condition of prehypertension was associated with body mass index obesity (OR: 5.14, CI: 2.70 to 9.79), male gender (OR: 9.41, CI: 5.41 to 16.36), living off campus on their own (OR: 3.18, CI: 1.35 to 7.48), living with parents or guardians (OR: 2.83, CI: 1.20 to 6.60), and 19 years of age (OR: 2.81, CI: 1.55 to 5.11). CONCLUSION One out of every 7 young adults presented with prehypertension. This condition is associated with established risk factors.

Forty-four-hour interdialytic ambulatory blood pressure monitoring and cardiovascular risk in pediatric hemodialysis patients. Clin Kidney J 2013; 7:33-9. [PMID: 25859347 PMCID: PMC4389162 DOI: 10.1093/ckj/sft149] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2013] [Accepted: 11/22/2013] [Indexed: 12/14/2022] Open
Abstract
Background Children undergoing chronic hemodialysis are at risk of cardiovascular disease and often develop left ventricular hypertrophy (LVH). Twenty-four-hour ambulatory blood pressure monitoring (ABPM) is known to better predict cardiovascular morbidity than casual blood pressure (BP) measurement. Given the BP variability attributed to interdialytic fluid overload, 44-h ABPM should better delineate cardiovascular morbidity in pediatric hemodialysis patients. Methods In this cross-sectional study, 17 children (16.7 ± 2.9 years) on chronic hemodialysis underwent 44-h interdialytic ABPM and routine echocardiogram. Left ventricular mass index (LVMI) was calculated by height-based equation; LVH was defined as an LVMI in the ≥95th percentile for height-age and gender. Hypertension was defined by the recommendations of the Fourth Report of the National High Blood Pressure Education Program for casual measurements, and by those of the American Heart Association for ABPM. Results Twenty-four percentage of patients were hypertensive by casual post-dialytic systolic BP, whereas 59% were hypertensive by ABPM. Eighty-eight percentage of patients had abnormal cardiac geometry: 53% had LVH. Thirty-five percentage (6 of 17) had masked hypertension, including four with abnormal cardiac geometry, of which, three had LVH. LVMI correlated with ABPM, but not with casual measurements. Strongest correlations with an increased LVMI were with 44-h diastolic BP: at night (r = 0.53, P = 0.03) and total load (r = 0.57, P = 0.02). LVH was similarly associated with 44-h nighttime BP: systolic (P = 0.02), diastolic (P = 0.01) and mean arterial (P = 0.01). Conclusions Casual BP measurement underestimates hypertension in pediatric hemodialysis patients and does not correlate well with indicators of cardiovascular morbidity. In contrast, 44-h interdialytic ABPM better characterizes hypertension, with nighttime parameters most strongly predicting increased LVMI and LVH.

Abstract
BACKGROUND The reduced activity of 11β hydroxysteroid dehydrogenase type 2 (11βHSD2) contributes to elevated blood pressure (BP) in clinical syndromes, but its effect on BP in the physiologic range is unclear. OBJECTIVES We examined the association of 11βHSD2 activity with BP in healthy children independent of known BP-related dietary and other factors and determined whether the diet-dependent acid load may constitute a dietary factor related to BP. DESIGN We conducted a cross-sectional analysis in 267 healthy children (age range: 4-14 y) who provided a 24-h urine sample, a parallel 3-d weighed dietary record, and 1-3 BP measurements ±1.5 y around the urine collection. The ratio of urinary free cortisone to cortisol measured by using a radioimmunoassay was used as an index for 11βHSD2. Urinary net acid excretion and the urinary and dietary potential renal acid load (PRAL) were used to predict the diet-dependent acid load. The PRAL was calculated as the sum of major mineral nonbicarbonate anions minus the sum of mineral cations. Sex-, age- and height-independent SD scores (SDSs) of systolic and diastolic BP were used as outcomes in linear regression analyses. RESULTS 11βHSD2 was inversely associated with systolic BP SDSs in basic models and in analyses adjusted for body size, maternal BP, breastfeeding, and dietary intakes of total energy, salt, and fruit and vegetables (P = 0.03). In models that included indexes of dietary acid load instead of fruit and vegetables, all 3 acid-load biomarkers were significantly (P = 0.006-0.02) directly related to systolic BP. CONCLUSION A lower 11βHSD2 activity and higher dietary acid load may independently contribute to higher systolic BP in healthy children.

Abstract
Prehypertension is a warning to individuals with resting blood pressures between 120/80 mmHg and 139/89 mmHg of an insidious progression of blood pressure towards hypertensive levels (≥ 140/90 mmHg). Prehypertension is associated with increased cardiovascular risk and end organ damage compared with individuals who are normotensive. This review primarily focuses on internal and external factors associated with the prevalence of prehypertension. Elucidating all of the factors associated with a rise in resting blood pressure and comparing the effects of medication versus lifestyle changes may aid the clinician in developing a preventive and/or treatment strategy for each individual.
