Association between perfluoroalkyl substance concentrations and blood pressure in adolescents

Objective: To analyze the influence of different number of blood pressure measurement on the detection of elevated blood pressure in Tibetan adolescents and provide scientific reference for standardizing the number of blood pressure measurement and accurately diagnosing elevated blood pressure in adolescents. Methods: Data were from the project "survey of the risk factors for elevated blood pressure among Tibetan adolescents" conducted from August to September 2018 in Shigatse in Tibet. A total of 2 822 Tibetan adolescents aged 12-17 years, including 1 275 boys (45.2%), were recruited by a convenient, stratified cluster sampling method. Each participant underwent three consecutive blood pressure measurements. Elevated blood pressure was defined according to the Health Industry Criterion of China: WS/T 610-2018 "Reference of screening for elevated blood pressure among children and adolescents aged 7-18 years" . Analysis of variance and χ(2) test were used to analyze the effect of different blood pressure measurement on blood pressure levels and detection of elevated blood pressure, respectively. Results: SBP and DBP decreased substantially across three consecutive blood pressure measurements[SBP: (112.7±9.7), (110.7±9.7) and (110.2±9.5) mmHg (1 mmHg=0.133 kPa); DBP: (62.7±8.2), (61.1±8.5) and (60.6±8.5) mmHg; P value for trend<0.001]. The detection rates of elevated blood pressure based on three blood pressure measurements were 12.8%, 8.7% and 7.9%, respectively (P value for trend <0.001). Of note, the difference in the detection of elevated blood pressure based on the second blood pressure measurement or based on the average value of the second and third blood pressure measurements showed no significance (8.7% and 7.2%, P=0.039). Conclusions: Blood pressure levels and the detection of elevated blood pressure in adolescents decreased substantially across three consecutive blood pressure measurements. The second blood pressure measurement might be sufficient for screening elevated blood pressure in adolescents.

BackgroundAlthough preterm birth predisposes for cardiovascular disease, recent studies in children indicate normal blood pressure and arterial stiffness. This prospective cohort study therefore assessed blood pressure and arterial stiffness in adolescents born very preterm due to verified fetal growth restriction (FGR).MethodsAdolescents (14 (13–17) years; 52% girls) born very preterm with FGR (preterm FGR; n = 24) and two control groups born with appropriate birth weight (AGA), one in similar gestation (preterm AGA; n = 27) and one at term (term AGA; n = 28) were included. 24-hour ambulatory blood pressure and aortic pulse wave velocity (PWV) and distensibility by magnetic resonance imaging were acquired.ResultsThere were no group differences in prevalence of hypertension or in arterial stiffness (all p ≥ 0.1). In boys, diastolic and mean arterial blood pressures increased from term AGA to preterm AGA to preterm FGR with higher daytime and 24-hour mean arterial blood pressures in the preterm FGR as compared to the term AGA group. In girls, no group differences were observed (all p ≥ 0.1).ConclusionsVery preterm birth due to FGR is associated with higher, yet normal blood pressure in adolescent boys, suggesting an existing but limited impact of very preterm birth on cardiovascular risk in adolescence, enhanced by male sex and FGR.ImpactVery preterm birth due to fetal growth restriction was associated with higher, yet normal blood pressure in adolescent boys.In adolescence, very preterm birth due to fetal growth restriction was not associated with increased thoracic aortic stiffness.In adolescence, very preterm birth in itself showed an existing but limited effect on blood pressure and thoracic aortic stiffness.Male sex and fetal growth restriction enhanced the effect of preterm birth on blood pressure in adolescence.Male sex and fetal growth restriction should be considered as additional risk factors to that of preterm birth in cardiovascular risk stratification.

This study was intended to clarify the relation between fasting insulin, lipids, and blood pressure in adolescents before the onset of hypertension and to examine the association of these data with similar data obtained in their parents. The participants in this study were 183 adolescents 14 to 18 years old (96 girls) completing a 4-year intervention trial and their parents (164 mothers, 122 fathers). Blood pressure was measured twice on the right arm in a seated position using a random-zero sphygmomanometer. Fasting blood samples were obtained for lipid and insulin analyses. Fasting insulin was significantly correlated with systolic blood pressure in the adolescents and also in the parents before and after adjustment for body mass index. Fasting insulin was correlated significantly with levels of cholesterol, triglycerides, and HDL and LDL cholesterol in the adolescents. It was correlated only with triglycerides and HDL-cholesterol in mothers and fathers. After adjustment for body mass index, the correlations between fasting insulin and lipids in the children were not significant. A significant relation was shown between children's systolic blood pressure and mothers' fasting insulin and systolic blood pressure. Significant correlations were found between the children's and fathers' triglycerides and HDL-cholesterol, whereas significant correlations were found for fasting insulin and all lipids between mothers and children, and these remained significant after adjustment for body mass index. These results show (1) a significant relation between fasting insulin and both lipids and systolic blood pressure in adolescents and (2) a significant relation for these factors between adolescents and their parents. Although weight appears to play an important role in this relation during adolescence, genetic and environmental factors other than those mediated via weight may control insulin metabolism within families. The data support a role for studies during early biological development to address these issues.

The prevalence of high blood pressure in adolescence is increasing with the number of adolescence at risk of overweight or overweight. Due to the known relationship between high blood pressure and increased risk of coronary artery disease (CAD) and stroke, this is an obvious health concern for adolescent children. PURPOSE: To characterize the incidence of high normal blood pressure and hypertension in a large population of ninth grade, physical education students. METHODS: 884 ninth grade, physical education students (14 ± 1 yrs) participated. Blood pressure was initially recorded with an automated device (Omron, HEM-907XL). If the initial automated reading was above 120/80 mmHg, then a manual ausculatory re-measurement was taken. Blood pressure was classified as high normal blood pressure if the reading fell between the 90th and 95th percentile based on the CDC growth charts (National high blood pressure education program working group on high blood pressure in children and adolescents, 2001), while hypertension was defined as a reading above the 95th percentile. Frequency of high normal blood pressure and hypertension was calculated for two groups based on BMI: at risk for being overweight or overweight students and normal weight students. RESULTS: Overall, 8.5% of students were classified as having high normal blood pressure and 4.8% were considered hypertensive. The incidence was greater for high normal blood pressure for the at risk for being overweight or overweight group (11.9%) compared to the normal weight students (7.4%). Hypertension was present in 7.3% of the at risk for being overweight or overweight population and 3.9% of the normal weight population. The at risk for being overweight or overweight group and normal weight group had a mean systolic blood pressure of 117.5 ± 9 mmHg and 112.8 ±10 mmHg, respectively, and a mean diastolic blood pressure of 64.7 ± 7 mmHg and 61.2 ± 8 mmHg, respectively. CONCLUSION: Our data indicates that a large percentage of the at risk for being overweight or overweight population (19.2%) has elevated blood pressure. At risk for being overweight or overweight students have a greater incidence of high normal blood pressure, and are twice as likely as normal weight students to have hypertension. The at risk for being overweight or overweight group also has a higher mean systolic and diastolic blood pressure values. This is alarming because elevated blood pressure is associated with an increased risk of CAD and stroke, and is in itself a progressive chronic disease.

This paper reviewed the available research literature to determine the role of exercise training in reducing resting blood pressure in adolescents. Similar to the adult population, there is little evidence to support the efficacy of exercise training for reducing resting blood pressure in normotensive adolescents, although several studies reported small decreases in either or both systolic and diastolic pressure. In hypertensive adolescents, aerobic-type exercise training consistently reduced both systolic and diastolic pressure, but seldom to completely normal levels. Resistance training has not been studied as extensively, but may be of some benefit. It is recommended that chronic aerobic and strength activities be part of an overall health maintenance program.

IntroductionThe burden of cardiovascular disease in Sub-Saharan Africa has increased in recent years, and high blood pressure is the leading cause. One established risk factor for hypertension and cardiovascular disease is dietary salt intake. The World Health Organisation has highlighted low-sodium salt substitutes (LSSS) as a potential method to lower sodium intake. LSSS enriched with potassium may additionally support improving sodium-potassium balance. Studies in India and China have investigated the impact of LSSS on reducing sodium intake and the risk of stroke and hypertension in adults. However, evidence in African populations, and in particular youth, is lacking. As such, this protocol describes a phase 1 double-blinded randomised controlled trial to assess the efficacy of a potassium-enriched LSSS compared to traditional salt to improve urinary sodium-to-potassium ratio and blood pressure in African adolescents and their families.MethodsWe will enrol 600 adolescents (13–19 years old) and their primary caregivers living in Soweto, South Africa. Adolescents and their households will be randomised to receive a LSSS or traditional table salt (NaCl) for a 16-week period. All other household salt products will be removed. Anthropometrics and questionnaire data will be collected at 0 and 16 weeks. Spot urine samples and blood pressure will be collected at 0, 4, 12 and 16 weeks. Safety screening for kidney function will be conducted on household members at baseline. The trial protocol received ethics approval from the University of Witwatersrand Medical Human Research Ethics Committee (M221056).DiscussionThe obtained results will, to the best of our knowledge, be the first in an African population to provide insights into the efficacy of a potassium-enriched LSSS in improving urinary sodium-to-potassium ratio and blood pressure.Trial registrationThis trial is registered with the Pan African Clinical Trials Registry (https://pactr.samrc.ac.za); identifier: PACTR202306727520808 (09 June 2023).Supplementary InformationThe online version contains supplementary material available at 10.1186/s13063-025-09184-z.

Background: Obesity is associated with increased risk for high blood pressure (BP). Although a routine BP measurement is indicated for all children visiting pediatric practice, recognition of children particularly at risk may save times. The aim of this study was to assess the cut-off point for body mass index (BMI) and waist-to-height ratio (WHtR) to predict high BP in adolescents. Methods: We conducted a cross-sectional study on 928 children aged 11 to 16 years in Yogyakarta. BP were measured using standard technique described by The Fourth Report on The Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents. BMI was adjusted for age and sex using the WHO 2007 growth reference. WHtR was ratio of waist circumference related to height in centimeters. Receiver operating characteristic (ROC) curves were used to estimate the best cut-offs. Results: The best cut-off point for BMI-for-age Z-score (BMIZ) to predict high BP was 0.51 with sensitivity and specificity of 82% (95% CI = 78-86) and 76% (95% CI = 67-78) for systolic BP and sensitivity and specificity of 82% (95% CI = 78-86) and 72% (95% CI = 68-76) for diastolic BP. The best cut-off point for WHtR was 0.45, with sensitivity of 76% (95% CI = 67-78) and specificity of 74% (95% CI = 71-79) for systolic BP and sensitivity of 76% (95% CI = 72-80) and specificity of 70% (95% CI = 61-75) for diastolic BP.Conclusion: BMIZ of 0.51 and WHtR of 0.45 are the best cut-off point to predict high BP in adolescents.

Adolescents are nutritionally vulnerable, and their intake is crucial to avoid nutritional problems during growth. Adolescent food consumption can be obtained from various types of food, one of them ultra-processed food (UPF). This study aims to determine the relationship between ultra-processed food consumption patterns and nutritional status and blood pressure in Catholic Junior High School Sudiang adolescents and Christian Elim High School Makassar. Methods: This study is a quantitative descriptive study with a cross-sectional design. The sample was selected using a proportional random sampling technique of 195 adolescents aged 13-18. UPF consumption was collected using the Semi Quantitative Food Frequency Questionnaire (SQ-FFQ). The research results show adolescents are overweight at 25.6% and obese at 21%; elevated blood pressure (BP) is 14.4%, and state hypertension (HTN) is 8.2%. In addition, obese adolescents with state 1 HTN were 17.1% and elevated BP by 24.4%, while overweight adolescents with state 1 HTN were 8% and elevated BP by 14%. There is a correlation between the amount of UPF consumption and nutritional status (p-value = 0.047). At the same time, the results were negative between the frequency of UPF consumption and nutritional status (p-value = 0.312), the amount of UPF consumption and BP (p-value = 0.289), and the frequency of UPF consumption and BP (p-value = 0.059). The study concludes a significant correlation between the amount of ultra-processed food consumption and nutritional status in adolescents. Further research and public health interventions are recommended to address the impact of UPF on adolescent health.

BackgroundAnthropometric indicators of obesity have been associated with blood pressure in adolescents. However, the accuracy of anthropometric indicators of obesity for screening for high blood pressure (HBP) in adolescents is not known. Thus, the aim of the present study was to summarize the set of evidence regarding the predictive ability of anthropometric indicators of obesity to identify HBP in adolescents.MethodsSearches were performed in five databases: MEDLINE, Web of Knowledge, Scopus, Scientific Electronic online (SciELO) and SportDiscus. The inclusion criteria for studies were: adolescents aged 10–19 years or mean age included in this range, observational and intervention studies, studies that proposed cutoff points for anthropometric indicators of obesity, and studies in English, Portuguese and Spanish. The methodological quality of studies was assessed using the QUADAS-2 instrument.ResultsTen studies met the inclusion criteria and had their information summarized. Based on the information described in these studies, the anthropometric indicators body mass index (BMI), waist circumference (WC), waist-to-height-ratio (WHtR), triceps skinfold thickness, body adiposity index, C index, body mass, waist-to-arm span ratio, arm fat area, average arm perimeter, fat percentage and arm span were likely to be used in high blood pressure (HBP) screening among adolescents. However, only one study showed acceptable values (moderate to high precision) in relation to the accuracy measurements of described cutoffs.ConclusionCaution is suggested in the use of anthropometric indicators of obesity for HBP screening in adolescents, in which a greater number of studies with accurate diagnostic tools are necessary.

The incidence of hypertension in adulthood begins with an increase in blood pressure since adolescence and high blood pressure in adolescents is also associated with an increased risk of Chronic Heart Disease (CHD) as an adult. Consumption of natrium may lead positively associated with an increase in blood pressure in adolescence. The novelty of this study is because it examines the relationship between sodium consumption and blood pressure in adolescent girls. This study aims to analyze the relationship between sodium consumption and blood pressure in adolescent girls in Tasikmalaya, West Java. This research is an observational study with a cross-sectional study design. The population in this study were all female adolescents aged 12-18 years. The independent variables in this study were total sodium consumption, sodium consumption in snacks, sodium consumption in the main menu and sodium contribution from snacks. The natrium intake was measured by non consecutive recall method. The dependent variable was blood pressure measured by sphygmomanometer Omron HEM8712. The data were analyze by Pearson product moment test. The average total sodium consumption is 506.6mg and blood pressure is 113mmH. There was a positive relationship between total daily sodium (p=0.00; r=0.240), sodium in snacks (p=0.002; 0.162), and sodium in daily menus (p=0.001; r-0.182) with blood pressure. The conclusion natrium intake was correlated with blood pressure in adolescent girls, therefore, they should aware with high sodium food.Keywords : Sodium; Blood pressure; Snacks; Adolescent girls.

The aim of this cross-sectional study was to investigate the association between consumption of sugar-sweetened and diet soft drinks with blood pressure (BP) in adolescents. Fifth graders of 20 public schools were invited to participate in an intervention aimed at behavioral dietary changes and had their BP, weight, and height measured at baseline. Type and frequency of soft drink consumption were assessed using a food and beverages frequency questionnaire, and students were classified as nonconsumers, sugar-sweetened soft drink consumers, and diet soft drink consumers. Of the 574 students invited, 512 were examined and 488 had their BP measured. Of these, 25 (5.1%) reported to be nonconsumers, 419 (85.9%) were sugar-sweetened soft drink consumers, and 44 (9%) were diet soft drink consumers. Mean SBP and DBP were 101.3/57.8, 102.6/58.8, and 106.0/61.3 mmHg for these three groups of consumption, respectively. After adjustment for sex, age, BMI, physical activity, addition of salt to food, and education of the head of the family, SBP was 5.4 mmHg higher in the diet soft drink consumers group compared with the nonconsumers group and 3.3 mmHg higher compared with the sugar-sweetened consumers group (P value of trend = 0.01). Moreover, DBP was also higher among diet soft drink consumers compared with nonconsumers, with a difference of 3.3 mmHg, and compared with sugar-sweetened consumers, with a difference of 2.3 mmHg (P value of trend = 0.04). The results indicate that the consumption of soft drink is associated with increased BP, which is further increased by drinking diet type sodas.

Physiological and Lifestyle Factors Associated With Abnormal Blood Pressure in Adolescents Before and After a School-Based Wellness Program in Michigan: A Report From Project Healthy Schools

Background: Although within the physiological range, overweight and obese adolescents, who are otherwise normal, have blood pressures at the higher side, whereas underweight adolescents have lower blood pressures when compared with the normal weight individuals. Aims and Objectives: (1) To assess the functional status of the cardiovascular system by measuring the heart rate (HR) and blood pressure in adolescents with different body mass indices (BMI) at rest. (2) To illustrate the response of the cardiovascular system to acute isotonic exercise by recording the HR and blood pressure in normal weight, underweight, and overweight adolescents. Materials and Methods: A total of 44 adolescents, aged between 17 and 19 years with different BMI, are the study group. Subjects are categorized into underweight, normal weight, and overweight/obese group based on their BMI. HR and blood pressure were recorded before and immediately after the acute bicycle ergometer exercise test, with three finger test and sphygmomanometer, respectively. Results: Increase in HR, systolic blood pressure (SBP), and pulse pressure (PP) in diastolic blood pressure (DBP) were observed immediately after the exercise (P = 0.000) among all the subjects. Before the exercise, SBP, DBP, and mean arterial blood pressure (P = 0.002, 0.008, and 0.003) and after the exercise, SBP and PP (P = 0.007 and 0.037) are significant among underweight, normal weight, and overweight subjects. Conclusion: Overweight/obese adolescents are having higher blood pressure at rest. SBP and PP were increased more in overweight/ obese adolescents after the exercise than the normal weight subjects.
