Relationship between the dietary inflammation index and hypertension in American children and adolescents: findings from the national health and nutrition examination survey 1999-2018

This study aimed to examine the relationship between the dietary inflammatory index (DII) and hypertension in children and adolescents using data from the National Health and Nutrition Examination Survey (NHANES) conducted between 1999 and 2018. The analysis included 18,460 participants aged 8 to 17 years, with 2,070 diagnosed with youth hypertension, defined as blood pressure above the 95th percentile for their age and gender. Dietary information was collected to calculate the DII, which was initially treated as a continuous variable and later categorized into tertiles. Multivariable weighted logistic regression and restricted cubic spline (RCS) analyses were conducted to explore the association between DII and youth hypertension. The results revealed a positive relationship between higher DII scores and increased likelihood of hypertension in youth, with both regression and RCS analyses showing a linear positive correlation after adjusting for potential confounders. The findings suggest that managing dietary inflammation may be an important strategy for preventing hypertension in children and adolescents.

Arterial hypertension in infants with congenital diaphragmatic hernia following surgical repair

Pulmonary hypertension (PH) and cardiac dysfunction are established comorbidities of congenital diaphragmatic hernia (CDH). However, there is very little data focusing on arterial hypertension in CDH. This study aims to investigate the incidence of arterial hypertension in neonates with CDH at hospital discharge. Archived clinical data of 167 CDH infants who received surgical repair of the diaphragmatic defect and survived for > 60 days were retrospectively analyzed. Blood pressure (BP) values were averaged for the last 7 days before discharge and compared to standard BP values for sex, age, and height provided by the AHA in 2004. BP values reaching or extending the 95th percentile were defined as arterial hypertension. The use of antihypertensive medication was analyzed at discharge and during hospitalization. Arterial hypertension at discharge was observed in 19 of 167 infants (11.3%) of which 12 (63%) were not receiving antihypertensive medication. Eighty patients (47.9%) received antihypertensive medication at any point during hospitalization and 28.9% of 152 survivors (n = 44) received antihypertensive medication at discharge, although in 45.5% (n = 20) of patients receiving antihypertensive medication, the indication for antihypertensive medication was myocardial hypertrophy or frequency control. BP was significantly higher in ECMO compared to non-ECMO patients, despite a similar incidence of arterial hypertension in both groups (13.8% vs. 10.1%, p = 0.473). Non-isolated CDH, formula feeding, and minimal creatinine in the first week of life were significantly associated with arterial hypertension on univariate analysis. Following multivariate analysis, only minimal creatinine remained independently associated with arterial hypertension.   Conclusion: This study demonstrates a moderately high incidence of arterial hypertension in CDH infants at discharge and an independent association of creatinine values with arterial hypertension. Physicians should be aware of this risk and include regular BP measurements and test of renal function in CDH care and follow-up. What is Known: • Due to decreasing mortality, morbidity is increasing in surviving CDH patients. • Pulmonary hypertension and cardiac dysfunction are well-known cardiovascular comorbidities of CDH. What is New: • There is a moderately high incidence of arterial hypertension in CDH infants at discharge even in a population with frequent treatment with antihypertensive medication. • A more complicated hospital course (ECMO, higher degree of PH, larger defect size) was associated with a higher risk for arterial hypertension.

Oral hygiene status and vascular aging in schoolchildren and their mothers

BACKGROUND

Poor oral hygiene, generally manifesting as dental caries, gingivitis, or periodontitis, is a common chronic condition among both children and adults worldwide and has been reportedly associated with hypertension and arterial stiffness mainly in adult patients. However, these associations have not been well-studied in children and adults in the general population. Therefore, we conducted this cross-sectional study to clarify the associations between oral hygiene indices and high blood pressure (BP)/hypertension and arterial stiffness as assessed by the cardio-ankle vascular index (CAVI) in children along with their mothers. The association between maternal oral hygiene and high BP in children was also examined based on the hypothesis that maternal awareness of oral hygiene is related to their children's oral hygiene.

METHODS

This study was conducted as an Adjunct Study of the Aichi Regional Sub-Cohort of the Japan Environment and Children's Study. Participating children (n = 220, 85-104 months old) and their mothers (n = 217, 29-52 years old) underwent dental/intra-oral examination and BP and CAVI assessment. High BP in children and hypertension in mothers were diagnosed according to corresponding American guidelines. Logistic regression analysis or analysis of covariance was used to examine the associations of poor oral hygiene indices with BP and CAVI.

RESULTS

Maternal dental caries ≥1 was associated with their hypertension (adjusted odds ratio [aOR]: 2.72, 95% confidence interval (CI): 1.12-6.61). Maternal dental plaque ≥1/3 was associated with maternal hypertension and children's high BP (aOR, 95% CI: 4.71, 1.33-16.73 and 5.67, 1.22-25.04, respectively). Maximum pocket depth ≥4 mm was associated with children's high BP (aOR: 6.85, 95% CI: 1.24-38.01). No associations were observed between oral hygiene indices and CAVI in children; however, there was a significant association between dental plaque and CAVI in mothers (F = 5.62, p < 0.01).

CONCLUSIONS

The small sample size, especially the case number, made it necessary to refrain from drawing unambiguous conclusion. The hypothesis that warrants further investigation based on the present study results is that poor oral hygiene is associated with high BP in children and hypertension and arterial stiffness in mothers, and maternal oral hygiene is associated with high BP in children.

Clinical usability of morning surge blood pressure for predicting future hypertension in a young population

Objective    Early diagnosis of hypertension (HT) is a critical issue for physicians. This study was conducted to determine if morning surge blood pressure (MSBP) could be used to predict future HT. The study also examined which demographic data in a regression model might help to detect future HT without any invasive procedure.Material and methods    A young population between 18 and 40 yrs of age was included in the study. MSBP and demographic data were used to determine an optimal model for predicting future HT by using Bayesian information criteria and binary logistic regression.Results    1321 patients with 24 hr ambulatory blood pressure monitoring were included in this study. The odds ratio of 10 units of increase in diastolic MSBP was 1.173511 in the model, which indicates that a 10 mmHg increase in diastolic MSBP increases the odds of future HT in the patient by 17.4 %. The odds ratio of age was 1.096365, meaning that at each age above 18 yrs, the patients' odds of future HT rise by 9.6 %. The odds ratios for gender (male) and previous HT were 1.656986 and 3.336759, respectively. The odds of future HT in males were 65 % higher than for females, and a history of HT implies that the odds of future HT were higher by 230 %.Conclusion    Diastolic MSBP can be used to predict HT in young individuals. In addition, age, male gender, and previous HT add more predictive power to diastolic MSBP. This statistically significant, predictive model could be useful in lessening or preventing future HT.

Pediatric Hypertension

Pediatric hypertension is becoming of increasing concern as the incidence rate increases alongside pediatric obesity. Practitioners need to be aware of the screening recommendations for early recognition and management of this disorder. Lifestyle modifications should be addressed early and specialty referral considered if the child is not improving. Further work-up to rule out secondary causes of pediatric hypertension should also be considered in any child with stage 2 hypertension and in those with persistently elevated blood pressures. Early recognition and management are key to not only preventing present complications but also future cardiovascular disease in adulthood.

Under‐recognition of pediatric hypertension diagnosis: Examination of 1 year of visits to community health centers

Pediatric hypertension is associated with significant target organ damage in children and cardiovascular morbidity in adulthood. Appropriate diagnosis and management per guideline recommendations are inconsistent. In this study, we determined the proportion of missed diagnosis of hypertension and prehypertension and appropriate follow‐up in pediatric patients, stratified by sex, age, race/ethnicity, and weight status. Based on the electronic health record (EHR) data from eight federally qualified health centers, among 62,982 children aged 3 to 18 years, 6233 (10%) had at least one abnormal blood pressure (BP) measurement over twelve months. Among those children whose recorded BPs met the criteria for prehypertension (N = 6178), 14.6% had a diagnosis in the EHR. These children were more likely to be White and have obesity compared with children who met the criteria but were not diagnosed with prehypertension. Among those who met the criteria for hypertension (N = 55), 41.8% had a diagnosis of hypertension in the EHR. Being diagnosed with hypertension was not associated with any examined patient characteristics. Over eleven months, 2837 children had BP ≥ 95th percentile on ≥ 1 visit. Only 13% had guideline‐adherent follow‐up within 1 month and were more likely to be older, female, and of Hispanic ethnicity or “other” race. Over six months, 2902 children had BP ≥ 90th percentile on one visit. 41% had guideline‐adherent follow‐up within 6 months and were more likely to be older, of either White, Hispanic, Asian race, or Hispanic ethnicity. In a community‐based setting, pediatric hypertension and prehypertension were persistently underdiagnosed with low adherence to recommended follow‐up.

Dental caries-related primary hypertension in children and adolescents: Cross-sectional study

BACKGROUND

Hypertension is a growing clinical problem in pediatric population. Also, the cause of hypertension is usually unknown and it may result from systemic inflammation related to tooth decay.

AIM

To estimate the potential association in cross-sectional study between tooth decay and hypertension in children and adolescents.

PATIENTS AND METHODS

Study group-65 children diagnosed with primary arterial hypertension; control subjects-44 normotensive children. Blood pressure, dental examination, measurement of salivary cortisol, alpha-amylase, secretory IgA, and lysozyme concentrations were performed in all of the children.

RESULTS

Hyper- and normotensive children had similar peripheral blood morphology and serum biochemical parameters, except of uric acid concentration, which was significantly higher in the study group (p = .047). Salivary evening concentrations of cortisol and alpha-amylase were significantly higher in hypertensive children (p = .002 and p = .004, respectively). Although 24-hr systolic blood pressure (SBP), including daytime and nighttime SBP, correlated with "decay," "microalbuminuria," "BMI," and "glomerular filtration rate" (r > .75, r > .7, r < .68, and r < .43, respectively), in multivariate analysis only "decay" was associated with hypertension both in children and in adolescents (p < .0001).

CONCLUSION

Tooth decay in children/adolescents might be regarded as a potent trigger factor of hypertension in individuals in whom all other causes of secondary arterial hypertension have been excluded.

Pediatric hypertension: A guideline update

The prevalence of pediatric hypertension is growing. Hypertension during childhood remains a major risk factor for adverse cardiovascular events later in life. NPs should be aware of current guidelines on screening, diagnosis, and treatment of hypertension in children to improve care for this patient population.

Pediatric Hypertension

Hypertension is an important and often overlooked problem in the pediatric population. In 2017, the American Academy of Pediatrics updated their guidelines for the diagnosis and management of hypertension. The new guidelines include a refined definition of the blood pressure stages and also a new diagnostic reference table with updated data excluding those with overweight or obesity. It also simplified the diagnostic criteria for adolescents and provided a screening table for easier use in the clinical setting. Along with the simplified diagnostic criteria, the new guidelines stress the importance of accurate blood pressure measurements and the growing importance of ambulatory blood pressure monitoring. With these revised guidelines, the diagnosis and management of blood pressure in the pediatric population should be clearer and easier to implement in clinical practice.

A Case-Control Study of Salivary Redox Homeostasis in Hypertensive Children. Can Salivary Uric Acid be a Marker of Hypertension?

Oxidative stress plays a critical role in the pathogenesis of hypertension; however, there are no data on salivary redox homeostasis and salivary gland function in children with hypertension. A total of 53 children with hypertension and age- and sex-matched controls were classified for the study. The antioxidant barrier and oxidative/nitrosative stress were evaluated in non-stimulated (NWS) and stimulated (SWS) whole saliva, plasma, and erythrocytes, with Student's t-test and Mann-Whitney U-test used for statistical analysis. We demonstrated that the activities of superoxide dismutase, catalase, and peroxidase were significantly higher in NWS, SWS, and erythrocytes of children with hypertension, similar to oxidative damage in proteins (advanced glycation end products) and lipids (malondialdehyde) as well as nitrosative stress markers (peroxynitrite and nitrotyrosine). The level of uric acid (UA) was significantly higher in NWS, SWS, and plasma of children with hypertension. UA concentration in SWS correlated positively with systolic and diastolic blood pressure and UA content in plasma. This parameter differentiates children with hypertension from healthy controls (AUC = 0.98) with a high degree of sensitivity (94%) and specificity (94%). Stimulated salivary flow was significantly lower in the hypertension group, similar to total protein content and salivary amylase activity. In summary, childhood hypertension is associated with hyposalivation as well as disturbances in antioxidant defense and enhanced oxidative/nitrosative damage both in the plasma/erythrocytes as well as saliva. Salivary UA may be a potential biomarker of hypertension in children.
