Body Mass Index and Hypertension as Mediators of the Association Between Age at Menarche and Subclinical Atherosclerosis: A Sex-Specific Mendelian Randomization Analysis. J Am Heart Assoc 2024; 13:e032192. [PMID: 38979809 PMCID: PMC11292777 DOI: 10.1161/jaha.123.032192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Accepted: 05/22/2024] [Indexed: 07/10/2024]
Abstract
BACKGROUND Early age at menarche (AAM) has been associated with a higher risk of carotid artery intima-media thickness (cIMT), an indicator of subclinical vascular disease, albeit the mechanisms underlying this association remain elusive. A better understanding of the relationship between AAM, modifiable cardiometabolic risk factors, and subclinical atherosclerosis may contribute to improved primary prevention and cardiovascular disease treatment. We aimed to investigate the putative causal role of AAM on cIMT, and to identify and quantify the potentially mediatory effects of cardiometabolic risk factors underlying this relationship. METHODS AND RESULTS We conducted linkage disequilibrium score regression analyses between our exposure of interest, AAM, our outcome of interest, cIMT and potential mediators of the AAM-cIMT association to gauge cross-trait genetic overlap. We considered as mediators the modifiable anthropometric risk factors body mass index (BMI), systolic blood pressure (SBP), lipid traits (total cholesterol, triglycerides, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol), and glycemic traits (fasting glucose). We then leveraged the paradigm of Mendelian randomization to infer causality between AAM and cIMT, and to identify whether cardiometabolic risk factors served as potential mediators of this effect. Our analyses showed that genetically predicted AAM was inversely associated with cIMT, BMI, SBP, and triglycerides, and positively associated with high-density lipoprotein, low-density lipoprotein, and total cholesterol. We showed that the effect of genetically predicted AAM on cIMT may be partially mediated through BMI (20.1% [95% CI, 1.4% to 38.9%]) and SBP (13.5% [95% CI, 0.5%-26.6%]). Our cluster-specific Mendelian randomization revealed heterogeneous causal effect estimates of age at menarche on BMI and SBP. CONCLUSIONS We highlight supporting evidence for a potential causal association between earlier AAM and cIMT, and almost one third of the effect of AAM on cIMT may be mediated by BMI and SBP. Early intervention aimed at lowering BMI and hypertension may be beneficial in reducing the risk of developing subclinical atherosclerosis due to earlier age at menarche.

[PMID: 38962763 PMCID: PMC11220196 DOI: 10.3389/fpubh.2024.1409214] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2024] [Accepted: 05/27/2024] [Indexed: 07/05/2024] Open
Abstract
Background To explore the relationship between body mass index (BMI), age, sex, and blood pressure (systolic blood pressure, SBP; diastolic blood pressure, DBP) in children during COVID-19, providing reference for the prevention and screening of hypertension in children. Methods This study adopted a large-scale cross-sectional design to investigate the association between BMI and blood pressure in 7-17-year-old students in City N, China, during COVID-19. Thirty-six primary and secondary schools in City N were sampled using a stratified cluster sampling method. A total of 11,433 students aged 7-17 years in City N, China, were selected for blood pressure (Diastolic blood pressure, DBP, Systolic blood pressure, SBP), height, and weight, Resting heart rate (RHR), chest circumference, measurements, and the study was written using the STROBE checklist. Data analysis was conducted using SPSS 26.0, calculating the mean and standard deviation of BMI and blood pressure for male and female students in different age groups. Regression analysis was employed to explore the impact of BMI, age, and sex on SBP and DBP, and predictive models were established. The model fit was evaluated using the model R2. Results The study included 11,287 primary and secondary school students, comprising 5,649 boys and 5,638 girls. It was found that with increasing age, BMI and blood pressure of boys and girls generally increased. There were significant differences in blood pressure levels between boys and girls in different age groups. In regression models, LC, Age, BMI, and chest circumference show significant positive linear relationships with SBP and DBP in adolescents, while RHR exhibits a negative linear relationship with SBP. These factors were individually incorporated into a stratified regression model, significantly enhancing the model's explanatory power. After including factors such as Age, Gender, and BMI, the adjusted R2 value showed a significant improvement, with Age and BMI identified as key predictive factors for SBP and DBP. The robustness and predictive accuracy of the model were further examined through K-fold cross-validation and independent sample validation methods. The validation results indicate that the model has a high accuracy and explanatory power in predicting blood pressure in children of different weight levels, especially among obese children, where the prediction accuracy is highest. Conclusion During COVID-19, age, sex, and BMI significantly influence blood pressure in children aged 7-17 years, and predictive models for SBP and DBP were established. This model helps predict blood pressure in children and reduce the risk of cardiovascular diseases. Confirmation of factors such as sex, age, and BMI provide a basis for personalized health plans for children, especially during large-scale infectious diseases, providing guidance for addressing health challenges and promoting the health and well-being of children.

Abstract
The progress in research on the physiology of the cardiovascular system made in the last 100 years allowed for the development of the pathogenesis not only of secondary forms of hypertension but also of primary hypertension. The main determinants of blood pressure are described by the relationship between stroke volume, heart rate, peripheral resistance, and arterial stiffness. The theories developed by Guyton and Folkow describe the importance of the volume factor and total peripheral resistance. However, none of them fully presents the pathogenesis of essential hypertension. The multifactorial model of primary hypertension pathogenesis developed by Irving Page in the 1940s, called Page's mosaic, covers most of the pathophysiological phenomena observed in essential hypertension. The most important pathophysiological phenomena included in Page's mosaic form a network of interconnected "nodes". New discoveries both from experimental and clinical studies made in recent decades have allowed the original Page mosaic to be modified and the addition of new pathophysiological nodes. Most of the clinical studies confirming the validity of the multifactorial pathogenesis of primary hypertension concern adults. However, hypertension develops in childhood and is even perinatally programmed. Therefore, the next nodes in Page's mosaic should be age and perinatal factors. This article presents data from pediatric clinical trials describing the most important pathophysiological processes associated with the development of essential hypertension in children and adolescents.

Abstract
Objective Primary hypertension has been shown to affect cognitive functions in adults but evidence in the pediatric population remain scarce and equivocal. We aimed to compare cognitive functioning between children diagnosed with primary hypertension and normotensive controls, with a focus on the role of different blood pressure (BP) parameters and body mass. Methods We conducted a single-center, prospective, cross-sectional study of children and adolescents (6-17 years old) with primary hypertension and age- and sex-matched normotensive controls. All participants underwent office BP, ambulatory BP monitoring (ABPM), and central BP measurements using an oscillometric device. Neurocognitive assessment consisted of evaluation of (i) intelligence quotient (IQ), (ii) categorical and phonemic fluency, (iii) verbal memory (verbal-logical story recall), and (iv) non-verbal computerized cognitive assessment. Results The study included a total of 59 patients with primary hypertension (14 ± 3 years) and 37 normotensive controls (14 ± 3 years). Participants in the primary hypertension group had a significantly higher body mass index z-score (BMIz: 2.1 ± 1.4 vs. 0.7 ± 0.9, p < 0.001), and 85% received antihypertensive therapy. Participants with primary hypertension showed worse performance in the domains of reaction speed, attention and processing speed, visual memory, new learning, and phonemic fluency. After adjusting for BMIz, only the differences in the reaction speed tasks remained significant. None of the BP parameters was associated with cognitive outcomes after adjustment for age, sex, and BMIz. BMIz associated with tasks of visual memory, new learning, spatial planning, and working memory, independent of age and sex. Conclusion Children and adolescents diagnosed with primary hypertension exhibit worse performance in the cognitive domains of reaction speed, attention, processing speed, visual memory, and new learning. These differences to healthy controls can be partially attributed to accompanying increase of body mass.

Abstract
BACKGROUND Arterial hypertension is the greatest cause of morbidity and mortality worldwide. Our aim was to investigate the prevalence of and factors associated with high blood pressure (HBP) among adolescents. METHODS AND RESULTS The Pelotas 2004 Birth Cohort included 4231 newborns from hospital births in Pelotas, Brazil. A digital automatic OMRON sphygmomanometer (model HEM 742) was used to measure blood pressure on 3 occasions (at 6, 11, and 15 years of age). Those with blood pressure ≥95th percentile for age, height, and sex on each of the 3 occasions were considered as presenting HBP. Independent variables included family (income and history of arterial hypertension), maternal (schooling, age, pregestational body mass index, and smoking during pregnancy), and adolescent characteristics at birth (sex, skin color, gestational age, intrauterine growth, and systolic and diastolic genetic factors), and at 15 years (sleep, physical activity, sodium intake, screen time, work, body mass index, fat mass index, fat-free mass index, growth pattern, and puberty status). The prevalence of HBP (95% CI) was calculated. Crude and adjusted odds ratios (ORs) stratified by sex were obtained by logistic regression. A total of 1417 adolescents with complete information on blood pressure on the 3 occasions were analyzed. The prevalence of HBP was 3.2% (95% CI, 1.9%-4.5%) in female adolescents and 4.3% (95% CI, 2.8%-5.8%) in male adolescents. Female adolescents with a family history of arterial hypertension had a 3 times higher chance of HBP than their counterparts (OR, 3.1 [95% CI, 1.26-7.54]). In male adolescents, excessive maternal pregestational weight was associated with a 2.3-fold increase in the chance of HBP. In both sexes, excessive adolescent weight was associated with HBP (ORs, 3.5 and 5.0, for female and male adolescents, respectively). A higher fat mass index and fat-free mass index in female (ORs, 1.4 and 1.2, respectively) and male adolescents (ORs, 2.5 and 3.0, respectively) increased the chance of HBP. Among male adolescents, the chance of HBP was higher among those with rapid weight gain between 48 months and 6 years and between 6 and 11 years and rapid height gain between 6 and 11 years. CONCLUSIONS Higher fat mass in both sexes and rapid weight gain in male adolescents are risk factors for HBP in adolescents aged 15 years, potentially amenable to prevention.

Abstract
OBJECTIVES The primary objective of this study is to examine the secular trends in blood pressure levels from 2012 to 2022 in eastern China. Additionally, to compare two standards [International Blood Pressure Reference for Children and Adolescents (ICBP) and the National Blood Pressure Reference for Chinese Han Children and Adolescents (CCBP)], we calculate the 95th percentile of blood pressure levels for students in developed regions (ECCBP). Secondly, the study aims to investigate potential contributors to elevated blood pressure, including sex, age, behaviors, and mental health. Lastly, the study seeks to estimate the total population aged 7-18 years with elevated blood pressure in Eastern China based on three references. METHODS The data used in this study were obtained from the Student Health Surveillance program in Jiangsu Province, which has been collecting data since 2012. Trained project members, skilled nurses, and doctors measured anthropometric variables. Additionally, online student questionnaires were administered in 2017, 2019, and 2021 to collect personal information behavior patterns, and mental health. RESULTS The study examined blood pressure changes in 123 013 children and adolescents in Eastern China from 2012 to 2022. Significant increases were observed in systolic blood pressure (SBP) and pulse pressure difference. Prevalence of elevated blood pressure followed a similar trend with ECCBP and CCBP, ranging from 17.2%/16.3% (2012-2015) to 11.6%/14.6% (2020-2022). Notably, BP with ICBP showed a significant increase in both prevalence and population, from 12.6% [6 713 679, 95% confidence interval (CI): 6 708 931 to 6 718 427] to 14.5% (7 004 208, 95% CI: 6 999 411 to 7 009 004). The study further emphasizes the significant impact of various risk factors on elevated blood pressure among children and adolescents, particularly the detrimental effect of depression on blood pressure, with the odds ratios (OR) in 2021 being 1.310 (95% CI, 1.290-1.330) for ECCBP, 1.239 (95% CI, 1.223-1.255) for CCBP, and 1.189 (95% CI, 1.176-1.202) for ICBP. CONCLUSION The study revealed significant changes in the population and prevalence of elevated blood pressure in Eastern China from 2012 to 2022. The findings indicate a decline in the prevalence of elevated blood pressure (referred to as CCBP or ECCBP), while highlighting an increasing trend in elevated blood pressure (referred to as ICBP). Untreated high blood pressure can lead to serious cardiovascular diseases in adulthood, underscoring the importance of early prevention and management, particularly through nonpharmacological methods and regular monitoring for students in Eastern China. Raising awareness among educators, parents, and healthcare providers about the association between mental health and elevated blood pressure is essential.

Abstract
PURPOSE OF REVIEW To review recent evidence on childhood hypertension across Africa, identifying knowledge gaps, challenges and priorities, and highlight clinical perspectives in managing primary hypertension. RECENT FINDINGS Only 15 of the 54 African countries reported on absolute blood pressure (BP) measures, elevated BP, pre- and/or hypertension. The reported hypertension prevalence ranged between 0.0 and 38.9%, while elevated BP and/or pre-hypertnesion ranged from 2.7 to 50.5%. Childhood BP nomograms are lacking across Africa and the rates of hypertension were based on guidelines developed in countries with the lowest to no number of children from African ancestry. The recent studies across Africa also showed little to no detail when reporting BP specific methodology. No recent data informing the use or effectiveness of antihypertensive agents in children and adolesents are available. Childhood hypertension is on the rise, while data from Africa remains vastly under-represented. Collaborative research, resources, and policies need to be strengthened in addressing the growing public health concern of childhood onset hypertension on this continent.

Abstract
Cardiovascular diseases (CVD) may be manifested from a very early age. Genetic and environmental (epigenetic) factors interact to affect development and give rise to an abnormal phenotypical expression of genetic information, although not eliciting changes in the nucleotide sequence of DNA. It has been scientifically proven that increased oxidative stress (OS) caused by disease (overweight, obesity, diabetes), nutritional imbalances, unhealthy lifestyles (smoking, alcohol, substance abuse) in the mother during pregnancy may induce placental dysfunction, intrauterine growth restriction, prematurity, low birth weight, postnatal adiposity rebound, metabolic alterations and consequent onset of traditional cardiovascular risk factors. OS represents the cornerstone in the onset of atherosclerosis and manifestation of CVD following an extended asymptomatic period. OS activates platelets and monocytes eliciting the release of pro-inflammatory, pro-atherogenic and pro-oxidising substances resulting in endothelial dysfunction, decrease in flow-mediated arterial dilatation and increase in carotid intima-media thickness. The prevention of CVD is defined as primordial (aimed at preventing risk factors development), primary (aimed at early identification and treatment of risk factors), secondary (aimed at reducing risk of future events in patients who have already manifested a cardiovascular event), and tertiary (aimed at limiting the complex outcome of disease). Atherosclerosis prevention should be implemented as early as possible. Appropriate screening should be carried out to identify children at high risk who are apparently healthy and implement measures including dietary and lifestyle changes, addition of nutritional supplements and, lastly, pharmacological treatment if risk profiles fail to normalise. Reinstating endothelial function during the reversible stage of atherosclerosis is crucial.

Abstract
OBJECTIVES To examine the longitudinal course for the development of elevated blood pressure (BP)/hypertension and cardiac damage in adolescents. STUDY DESIGN From the Avon Longitudinal Study of Parents and Children, UK birth cohort, 1856 (1011 female) 17-year-old adolescents were followed up for 7 years. BP and echocardiography were assessed at ages 17 and 24 years. Elevated/hypertensive BP was defined as ≥130 mm Hg systolic and ≥85 mm Hg diastolic. Left ventricular (LV) mass indexed for height2.7 (LVMI2.7) ≥51 g/m2.7 was defined as LV hypertrophy (LVH) and LV diastolic function (LVDF) E/A <1.5 as LVD dysfunction (LVDD). Data were analyzed with generalized logit mixed-effect models and cross-lagged structural equation temporal path models adjusting for cardiometabolic and lifestyle factors. RESULTS Over follow-up, the prevalence of elevated systolic BP/hypertension increased from 6.4% to 12.2%, LVH from 3.6% to 7.2%, and LVDD from 11.1% to 16.3%. Cumulative elevated systolic BP/hypertension was associated with worsening LVH in female participants (OR 1.61, CI 1.43-1.80 P < .001) but not in male participants. Elevated systolic BP/hypertension was associated with worsening LVDD in male and female participants. Elevated diastolic BP/hypertension was associated with worsening LVH in male and female participants. In cross-lagged temporal path models, higher baseline systolic BP was associated with LVDF (β = 0.09, SE = 0.002, P = .029) but not LVMI2.7 at follow-up. Higher baseline cardiac indices were not associated with follow-up systolic BP. Higher baseline diastolic BP was associated with follow-up higher cardiac indices except LVDF. Baseline LVMI2.7 was not associated with follow-up diastolic BP. CONCLUSIONS Elevated BP/hypertension may temporally precede premature cardiac damage in youth.

Abstract
Mainstream transcriptome profiling of susceptibility versus resistance to age-related diseases (ARDs) is focused on differentially expressed genes (DEGs) specific to gender, age, and pathogeneses. This approach fits in well with predictive, preventive, personalized, participatory medicine and helps understand how, why, when, and what ARDs one can develop depending on their genetic background. Within this mainstream paradigm, we wanted to find out whether the known ARD-linked DEGs available in PubMed can reveal a molecular marker that will serve the purpose in anyone's any tissue at any time. We sequenced the periaqueductal gray (PAG) transcriptome of tame versus aggressive rats, identified rat-behavior-related DEGs, and compared them with their known homologous animal ARD-linked DEGs. This analysis yielded statistically significant correlations between behavior-related and ARD-susceptibility-related fold changes (log2 values) in the expression of these DEG homologs. We found principal components, PC1 and PC2, corresponding to the half-sum and the half-difference of these log2 values, respectively. With the DEGs linked to ARD susceptibility and ARD resistance in humans used as controls, we verified these principal components. This yielded only one statistically significant common molecular marker for ARDs: an excess of Fcγ receptor IIb suppressing immune cell hyperactivation.

Abstract
BACKGROUND Primary hypertension may lead to early vascular ageing. We aimed to evaluate differences between expected vascular age based on pulse wave velocity (PWV)/carotid intima-media thickness (cIMT) and actual chronological age (CHA) in adolescents with primary hypertension. METHODS Three hundred and fifty-two children (median age of 15.5 years) with office hypertension and 64 normotensive healthy children of the same age underwent anthropometry, office and ambulatory blood pressure (BP), left ventricular mass index, cIMT, PWV, pulse wave analysis and biochemistry measurements. Vascular age was calculated using pooled pediatric and adult normative PWV and cIMT data. The difference between vascular age and CHA was calculated in relation to the 90th percentile for PWV (PWVAgeDiff90) and the 95th percentile for cIMT (cIMTAgeDiff95). RESULTS One hundred and sixty-six patients had white-coat hypertension (WCH), 32 had ambulatory prehypertension (AmbPreHT), 55 had isolated systolic hypertension with normal central SBP (ISH+cSBPn), 99 had elevated office, ambulatory and cSBP (true hypertension, tHT). The differences between vascular age (both PWV and cIMT based) and CHA were significantly higher in AmbPreHT and tHT compared with normotension, WCH and ISH+cSBPn. Median PWVAgeDidff90 was -3.2, -1.2, -2.1, +0.8 and +0.3 years in normotension, WCH, ISH+cSBPn, AmbPreHT and tHT, respectively. Median cIMTAgeDiff95 was -8.0, -6.3, -6.8, -3.8 and -4.3 years in normotension, WCH, ISH+cSBPn, AmbPreHT and tHT, respectively. Significant predictors of PWVAge90Diff were the DBP and serum cholesterol, whereas cSBP and augmentation index were significant predictors of cIMTAgeDiff95. CONCLUSION Children with AmbPreHT and tHT show accelerated vascular age compared with their normotensive peers.

Abstract
Primary hypertension (PH) is most common during adolescence with increasing prevalence globally, alongside the epidemic of obesity. Unlike in adults, there are no data on children with uncontrolled hypertension and their future risk of hard cardiovascular and cerebrovascular outcomes. However, hypertension in childhood is linked to hypertensive-mediated organ damage (HMOD) which is often reversible if treated appropriately. Despite differing guidelines regarding the threshold for defining hypertension, there is consensus that early recognition and prompt management with lifestyle modification escalating to antihypertensive medication is required to ameliorate adverse outcomes. Unfortunately, many unknowns remain regarding pathophysiology and optimum treatment of childhood hypertension.

Abstract
Arterial stiffness is a strong predictor of cardiovascular events and all-cause mortality in middle-aged and old adults. Arterial stiffness has been limited to being an intermediate marker of atherosclerotic cardiovascular events in adolescents and young adult studies. The paucity of normative longitudinal data and repeated gold-standard assessments of arterial stiffness among the young population has occasioned a huge knowledge gap in its clinical utility. This review summarizes recent longitudinal evidence in a large adolescent population, supporting the value of arterial stiffness as a novel risk factor for hypertension, overweight/obesity and insulin resistance. Preventing or decreasing arterial stiffness during adolescence may confer cardiometabolic health benefits in later life, but further pathological and mechanistic research is needed. The review also offers suggestions for incorporating arterial stiffness measures into routine paediatric and young adult clinical practice.

Abstract
OBJECTIVE Early effects of primary hypertension on arterial structure and function in children and young people (CYP) and their determinants remain elusive. We aimed to review independent determinants of carotid intima-media thickness (cIMT), carotid wall cross-sectional area (WCSA) and carotid-femoral pulse wave velocity (cfPWV) in CYP with primary hypertension. METHODS We performed a systematic review of studies reporting multivariable analysis of cfPWV, cIMT and WCSA in CYP (up to 25 years of age) with primary hypertension. Literature search was performed in PubMed database and 13, 12 and two articles including 3860 (age range 4-25 years, 50% male individuals), 2038 children (5-25 years, 55% male individuals) and 136 children (5-17 years, 85% male individuals) were selected for final analysis of cfPWV, cIMT and WCSA, respectively. RESULTS Ninety and 86% of the studies reported higher cfPWV and cIMT in CYP with elevated blood pressure (BP) compared with normotensive controls. Different indices of BP were positively associated with cfPWV in 92% of studies, whereas BMI showed association in 31%. Carotid IMT associated with BP indices in 50% and with BMI in 25% of the studies. WCSA was studied longitudinally and its improvement associated with decrease in measures of central obesity. CONCLUSION We found a disparity between the determinants of structural and functional impairment of arterial tree in CYP with primary hypertension. In contrast to cIMT and WCSA, increase of cfPWV is almost exclusively determined by BP.

Abstract
Chimonanthus salicifolius (CS), the leaves of Chimonanthus salicifolius S. Y. Hu., is an effective tea to prevent and treat hypertension in China. This study aimed to explore the effect and mechanism of CS in the protection against vascular remodeling in hypertension. Spontaneously hypertensive rats (SHRs) were orally administered with aqueous extracts of CS for 6 months. The blood pressure and morphological changes of the aorta were measured. Their mechanisms were studied by combining chemical identification, network pharmacology analysis and validation in vivo. Hypertensive rats showed an impaired vascular structure and dyslipidemia as illustrated by the increase of the vascular media thickness and collagen deposition in the aorta. CS treatment exhibited significant beneficial effects on blood pressure control and aortal morphology. A total of 21 compounds from CS were identified, which were linked to 106 corresponding targeted genes for vascular remodeling. The network pharmacology predicted that CS prevented vascular remodeling through the endoplasmic reticulum stress pathway. The in vivo experiments further showed that CS treatment upregulated Glucose-Regulated Protein 78 and downregulated CCAAT-enhancer-binding protein homologous protein at both mRNA and protein levels, paralleling reduced apoptotic cells in the arterial wall. Additionally, CS diminished the low-density lipoprotein cholesterol levels, total cholesterol contents and triglyceride/high-density lipoprotein cholesterol ratios in the sera of SHRs, which might also contribute to its protection of vessels. Collectively, CS protects against vascular modeling by suppressing endoplasmic reticulum stress-related apoptosis in hypertension, and it could be a potential agent for the prevention and treatment of vascular modeling.

Abstract
OBJECTIVE The prevalence of hypertension in young adulthood, as well as the clinical characteristics associated with different hypertension subtypes, have been inconsistently described. Our aim was to assess the prevalence, time-trends and characteristics associated with isolated systolic hypertension (ISH), isolated diastolic hypertension and combined systodiastolic hypertension. METHODS Serial cross-sectional analysis, using data from the Swedish conscription registry, including 1701 314 (99.2% male) individuals from 1969 to 2010. Risk factor associations were assessed through multivariable logistic regression. RESULTS The prevalence of hypertension increased progressively during the study period, from 20.4% in 1969 to 29.3% in 2010, with ISH being the most common subtype (94.3%). ISH was associated with elevated resting heart rate (odds ratio 1.85, 95% confidence interval 1.84-1.86, per SD), increased exercise capacity (1.37, 1.36-1.39) and increased BMI (1.30, 1.29-1.31). Isolated diastolic hypertension and combined hypertension were also associated with elevated resting heart rate (1.37, 1.32-1.41 and 2.05, 1.99-2.11, respectively) and more strongly associated with increased BMI (1.36, 1.33-1.40 and 1.54, 1.51 - 1.58), but inversely associated with exercise capacity (0.79, 0.75-0.83 and 0.90, 0.86-0.95). CONCLUSION The prevalence of hypertension in young adulthood has increased substantially over time, predominantly due to an increase in ISH. Risk factor patterns differed between ISH and other forms of hypertension, suggesting potentially different underlying mechanisms.

Abstract
Dendritic cells (DCs) play an important role in T cell alterations in primary hypertension (PH). We determined the numbers and maturation markers of peripheral blood total DCs (tDCs), myeloid cells (mDCs), and plasmacytoid cells (pDCs) and their association with hypertension-mediated organ damage (HMOD) markers and selected immune parameters in 30 adolescents with white coat hypertension (WCH), 25 adolescents with PH and a group of 35 age- and sex-matched children with normotension. Using multicolor flow cytometry, expression of maturation markers (CD86 and CD83) in tDCs (Lin1-/HLA-DR+), myeloid DCs (Lin1-/HLA-DR+/CD11c+) (mDCs), and plasmacytoid DCs (Lin1-/HLA-DR+/CD123+) (pDCs) and the distribution of peripheral Th17-bearing and T-reg cells were defined. In subjects with hypertension, carotid intima-media thickness (cIMT), left ventricular mass index (LVMI), and pulse wave velocity (PWV) were assessed. Compared with WCH and subjects with normotension, subjects with hypertension had reduced tDC and pDC numbers, an increased percentage of mDC subsets, an elevated mDC/pDC ratio, an increased population of mature mDC and pDC subsets bearing CD83 of high density, a decreased subset of CD86-bearing pDCs, and increased expression of DC activation markers (HLA-DR, CD86), as well as CD11c (mDCs) and CD123 (pDCs). PWV, LVMI, and cIMT values correlated negatively with tDCs and pDCs and positively with mDC numbers. Expression of DC maturation/activation markers (CD83, CD86, HLA-DR, CD11c, and CD123) correlated positively with PWV. Certain DC characteristics of WCH subjects resembled those of PH subjects (decreased tDC frequency and upregulation of activation marker expression). These changes correlated with HMOD. WCH subjects presented a DC phenotype that was intermediate between the normotensive and hypertensive phenotypes.

Abstract
Background Menarche timing may not be directly associated with the risk of coronary artery disease (CAD). Therefore, we investigated the roles of metabolic factors in explaining the effect of age at menarche on CAD risk. Methods We identified women with age at menarche and CAD by using three analytical methods: Mendelian randomization (MR), logistic regression analysis, and Cox proportional hazard regression. The first two analyses were performed in the Taiwan Biobank (N = 71,923) study, and the last analysis was performed in the Chin-Shan Community Cardiovascular Cohort study (N = 1,598). We further investigated the role of metabolic factors in mediating the effect of age at menarche on CAD risk by using three complementary methods with mediation analyses. Results One standard deviation of earlier age at menarche was associated with a 2% higher CAD risk [odds ratio = 1.02, 95% confidence interval (CI) = 1.001-1.03] in the MR analysis, an 11% higher risk (odds ratio = 1.11, 95% CI = 1.02-1.21) in the logistic regression analysis, and a 57% higher risk (hazard ratio = 1.57, 95% CI = 1.12-2.19) in the Cox proportional hazard regression. All the analyses consistently supported the role of systolic blood pressure in mediating this effect. The MR results indicated that 29% (95% CI = 26%-32%) of the effect of genetically predicted earlier age at menarche on CAD risk was mediated by genetically predicted systolic blood pressure. Conclusion The results obtained using different analytical methods suggest that interventions aimed at lowering systolic blood pressure can reduce the cases of CAD attributable to earlier age at menarche.

Abstract
Background: Preliminary data suggest that target organ damage (TOD) and early vascular aging (EVA) may occur in children with normal blood pressure (BP). Objectives: To analyze TOD and EVA in normotensive (BP <95th percentile on ambulatory BP monitoring) type 1 diabetes children (T1D) in comparison to healthy controls (C). Subjects: 25 T1D aged 13.9 ± 2.6 years and 22 C aged 14.0 ± 3.4 years. Methods: We analyzed age- and height-related pulse wave velocity (PWV) Z-scores and expected PWV based on age, height, and mean arterial pressure (MAP). Expected vascular age based on measured PWV was calculated from pooled pediatric and adult PWV norms. Left ventricular mass index (LVMI), estimated glomerular filtration rate (eGFR), and urinary albumin/creatinine ratio (ACR) were obtained as markers of TOD. Results: T1D and C groups did not differ in anthropometry, ambulatory, LVMI, and ACR. However, median age- and height-related PWV Z-scores were higher in T1D compared to C (1.08 vs. 0.57, p = 0.006; 0.78 vs. 0.36, p = 0.02, respectively). Mean (±SD) difference between measured and expected PWV was 0.58 ± 0.57 in T1D vs. 0.22 ± 0.59 in C, p = 0.02. The mean (±SD) difference between chronological and expected vascular age was 7.53 ± 7.74 years in T1D vs. 2.78 ± 7.01 years in C, p = 0.04. Conclusion: Increased arterial stiffness and increased intraindividual differences between expected and measured PWV as well as between chronological and expected vascular age indicate that EVA may develop in T1D children even at normal ambulatory BP levels.
