Abstract
OBJECTIVE To evaluate the association between enteral sodium supplementation on growth and hypertension (HTN) in preterm infants. STUDY DESIGN A retrospective cohort study of infants born between 22-32 weeks and weighing 450-1500 grams (N = 821). Enteral sodium supplementation amounts, systolic blood pressures (SBP), weight gain, and other infant and maternal risk factors for HTN were electronically extracted. RESULTS Infants receiving sodium supplementation were smaller and less mature. Sodium supplementation improved serum sodium levels, weight gain, and head circumference growth without causing hypernatremia. There was no correlation between urine and serum sodium or urine sodium and weight gain. Although infants receiving sodium had higher average SBP and rates of HTN, analysis demonstrated sodium supplementation did not increase odds of hypertension (ORADJ 1.02;0.64-1.64). Postnatal steroids were associated with HTN. CONCLUSIONS In preterm infants with poor weight gain, enteral sodium supplementation improved growth without increasing hypertension or hypernatremia.

Abstract
Cardiovascular disease (CVD) risk factors in children have increased in prevalence. Dietary intake may modify risk. Data collected during a randomized trial testing the effect of a behavioral intervention on adiposity, blood pressure (BP), and left ventricular mass index (LVMI) were analyzed using multivariable regression to determine independent associations of sodium, sugar-sweetened beverage (SSB), and artificially sweetened beverage (ASB) intake with outcomes. High sodium intake (≥3.5 g) was associated with hypertensive BP (odds ratio 12.8; P = .027) in minimally adjusted models. High SSB intake (≥4 oz) was independently associated with body mass index z-score (β = .34; P = .035) and waist circumference z-score (β = .49; P = .022) in fully adjusted models. Any ASB intake was associated with LVMI in fully adjusted model (% change 38.22; P = .004). There was no effect modification between sodium and SSB on outcomes. Dietary factors explored in this study independently impacted CVD risk. Further effect measure modification should be explored in larger cohorts.

Abstract
BACKGROUND Early-life programming due to prematurity and very low birth weight (VLBW, <1500 g) is believed to contribute to development of hypertension, but the mechanisms remain unclear. Experimental data suggest that altered pressure natriuresis (increased renal perfusion pressure promoting sodium excretion) may be a contributing mechanism. We hypothesize that young adults born preterm will have a blunted pressure natriuresis response to mental stress compared with those born term. METHODS In this prospective cohort study of 190 individuals aged 18-23 years, 156 born preterm with VLBW and 34 controls born term with birth weight at least 2500 g, we measured urine sodium/creatinine before and after a mental stress test and continuous blood pressure before and during the stress test. Participants were stratified into groups by the trajectory at which mean arterial pressure (MAP) increased following the test. The group with the lowest MAP trajectory was the reference group. We used generalized linear models to assess poststress urine sodium/creatinine relative to the change in MAP trajectory and assessed the difference between groups by preterm birth status. RESULTS Participants' mean age was 19.8 years and 57% were women. Change in urine sodium/creatinine per unit increase in MAP when comparing middle trajectory group against the reference group was greater in those born preterm [β 5.4%, 95% confidence interval (95% CI) -11.4 to 5.3] than those born term (β 38.5%, 95% CI -0.04 to 92.0), interaction term P = 0.002. CONCLUSION We observed that, as blood pressure increased following mental stress, young adults born preterm exhibited decreased sodium excretion relative to term-born individuals.

Abstract
INTRODUCTION In adults, sodium-glucose cotransporter type 2 inhibitors have revolutionised the treatment of type 2 diabetes mellitus, heart failure, and chronic kidney disease. OBJECTIVE We aimed to review information on compassionate use, clinical pharmacology, efficacy, and safety of dapagliflozin and empagliflozin in children. METHODS We conducted a systematic review of published clinical trials, case reports, and observational studies in Medline, Excerpta Medica, and Web of Science databases from inception to September 2023. For the two randomised controlled trials on type 2 diabetes mellitus (T2DM), we implemented a meta-analysis on the primary outcome (mean difference in glycosylated haemoglobin [HbA1c] between intervention and placebo groups). Review Manager (RevMan), version 5.4.1, was used for this purpose. RESULTS Thirty-five articles (nine case reports, ten case series, one prospective non-controlled trial, four controlled randomised trials, two surveys, six pharmacokinetic studies, and three pharmacovigilance studies) were selected, in which 415 children were exposed to either dapagliflozin or empagliflozin: 189 diabetic patients (mean age 14.7 ± 2.9 years), 32 children with glycogen storage disease type Ib (GSD Ib), glucose-6-phosphatase catalytic subunit 3 (G6PC3) deficiency, or severe congenital neutropenia type 4 (8.5 ± 5.1 years), 47 children with kidney disease or heart failure (11.2 ± 6.1 years), 84 patients in pharmacokinetic studies (15.1 ± 2.3 years), and 63 patients in toxicological series. The effect of dapagliflozin and empagliflozin in T2DM was demonstrated by HbA1c reduction in two randomised trials among a total of 177 adolescents, with a mean HbA1c difference of -0.82% (95% confidence interval -1.34 to -0.29) as compared to placebo (no heterogeneity, I2 = 0%). Dosage ranged between 5 and 20 mg (mean 11.4 ± 3.7) once daily for dapagliflozin and between 5 and 25 mg (mean 15.4 ± 7.4) once daily for empagliflozin. Among the paediatric cases of GSD Ib, empagliflozin 0.1-1.3 mg/kg/day improved neutropenia, infections, and gastrointestinal health. Dapagliflozin (mean dosage 6.9 ± 5.2 mg once daily) was well-tolerated in children with chronic kidney disease and heart failure. Side effects were generally mild, the most frequent being hypoglycaemia in children with GSD Ib (33% of patients) or T2DM (14% of patients) on concomitant hypoglycaemic drugs. Diabetic ketoacidosis is rare in children. CONCLUSION Early evidence suggests that dapagliflozin and empagliflozin are well tolerated in children. A clinical pharmacology rationale currently exists only for adolescents with diabetes mellitus. PROSPERO REGISTRATION NUMBER CRD42023438162.

Abstract
Children born prematurely have greater lifetime risk for hypertension. We aimed to determine (1) the association between prematurity and cardiovascular disease (CVD) risk factors among 90 children with obesity and elevated blood pressure and (2) if dietary sodium intake modified these associations. Multivariable regression analysis explored for associations between prematurity (<37 weeks gestation; early gestational age) and low birth weight (<2.5 kg) with hypertension, left ventricular mass index (LVMI), and left ventricular hypertrophy (LVH). Effect modification by dietary sodium intake was also explored. Patients were predominately male (60%), black (78%), adolescents (13.3 years), and with substantial obesity (body mass index: 36.5 kg/m2). Early gestational age/low birth weight was not an independent predictor for hypertension, LVMI, or LVH. There was no effect modification by sodium load. Our results suggest the increased CVD risk conferred by prematurity is less significant at certain cardiometabolic profiles. Promoting heart-healthy lifestyles to prevent pediatric obesity remains of utmost importance to foster cardiovascular health.

Abstract
(1) Background: The aim of this study was to investigate the salt consumption by children and adolescents from the Silesian Province (Poland), taking into account the region's dietary traditions and the age of the students+. (2) Methods: 300 students aged 10-18 from different types of schools were enrolled in the study and divided into groups in terms of school, sex, and the state of their nutrition. A survey questionnaire about dietary habits, including the frequency and serving size with respect to 12 salty products, was used. On the basis of the frequency and the amount of consumed products, as well as the data on salt content, the amount of total daily intake of salt was estimated. (3) Results: The mean daily intake of salt by children and adolescents was 1.083 g (0.433 g of sodium); children aged 10-12 consumed the highest amount of salt (1.296 g/day) compared to pupils aged 13-15 (1.131 g of sodium) and adolescents aged 16-18 (0.863 g/day). (4) Conclusions: With age, as a result of various factors, the consumption of salt declines. The parents' impact and the familial socio-environmental factors begin to wane, and other factors start to have influence, e.g., school education of a healthy lifestyle and health behavior of peers.

Abstract
It is widely known that optimal nutrition in the first 1000 days of life positively impacts the child's development throughout adulthood. In this setting, salt should not be added to complementary feeding. In developed countries, salt intake is generally higher than recommended for children. Excessive salt intake is the major determinant of hypertension and is associated with several cardiovascular outcomes. Therefore, pediatricians have a key role in raising awareness among parents to avoid salt consumption in the first 1000 days of life to ensure better health for their children. Starting from a review of the literature published in PubMed/MedLine regarding the short- and long-term consequences of salt consumption during the first 1000 days of life, our comprehensive review aims to analyze the beneficial effects of avoiding salt at such a vulnerable stage of life as the first 1000 days. Obesity, hypertension, increased salt sensitivity, high sweet drink consumption, increased mortality, and morbidity persisting in adult age represent the principal consequences of a higher salt intake during the first 1000 days of life.

Abstract
Commercially produced complementary foods (CPCF), including ready-to-eat CPCF purées and meals, are gaining popularity among caregivers of older infants and young children (IYC) as a convenient alternative to home-prepared foods in low and middle-income countries. However, there is growing concern regarding the suitability of these products for older IYC, as they can contain high levels of sugar and/or sodium. Given the rapidly evolving market in Southeast Asia, it is crucial to monitor the appropriate composition and promotion of CPCF in the region. This study examined the nutrient composition and labelling practices of CPCF purées and meals sold in 2021 in the capital cities of seven Southeast Asian countries: Phnom Penh (Cambodia), Jakarta (Indonesia), Manila (Philippines), Bangkok (Thailand), Vientiane (Lao PDR), Hanoi (Viet Nam), Kuala Lumpur (Malaysia). The study adapted a nutrient profiling model from the WHO Regional Office for Europe to determine the proportion of products suitable for promotion for older IYC. The proportion of CPCF purées and meals that would require a high sugar front-of-pack warning based on the percentage energy from total sugar was also determined. Of the 459 CPCF purées/meals assessed, only 37.7% of the products met all nutrient composition requirements and none met all labelling requirements. In addition, most CPCF purées and meals were identified as having high total sugar content. To ensure that older IYC consume appropriate CPCF products, Southeast Asian countries need to implement and enforce regulations concerning the nutrient composition and labelling practices of CPCF purées and meals.

Abstract
In Southeast Asia, the increasing availability of commercially produced complementary foods (CPCF), including dry or instant cereals (CPCF cereals), has been noted, however, concerns exist around their nutrient profile and labelling practices. This 2021 study assessed the nutrient composition, labelling practices, and micronutrient content of CPCF cereals sold in the capital cities of seven Southeast Asian countries: Phnom Penh (Cambodia), Jakarta (Indonesia), Manila (Philippines), Bangkok (Thailand), Vientiane (Lao PDR), Hanoi (Vietnam), and Kuala Lumpur (Malaysia). The study adapted a nutrient profiling model from the WHO Regional Office for Europe to determine the proportion of products suitable for promotion for older infants and young children. Micronutrient content of fortified CPCF cereals was assessed against fortification levels specified in the Codex Alimentarius guideline for formulated complementary foods. Of the 484 products assessed, 184 (38.0%) met all nutrient composition requirements. Around one-third of CPCF cereals contained added sugars and/or sweeteners (37.2%) and high levels of sodium (28.9%). None of the CPCF cereals met all labelling requirements, primarily due to the presence of inappropriate claims on the labels. Most fortified CPCF cereals contained adequate amounts of critical micronutrients, such as calcium, iron, zinc, vitamin A, and vitamin D. However, rates of fortification varied across the seven countries, and almost a third (30.8%) of CPCF cereals were not fortified with any micronutrients. To support the appropriate promotion of CPCF in the region, Southeast Asian countries need to strengthen and enforce national binding legal measures, including national standards for the composition, labelling, and fortification of CPCF cereals.

Abstract
Diet in the early years of life may influence the development of chronic diseases later on. The aim of the present study was to investigate the dietary intake of 2- to 6-year-old Hungarian children. In 2013 and subsequently in 2016, cross-sectional surveys were conducted among parents of healthy children attending kindergarten in Hungary. We used a three-day food diary to record quantitative data of all the nutrients consumed by the children on two working days and one weekend day. The dietary intakes were compared to both the Hungarian recommended dietary allowances and the European Food Safety Authority recommendations. The nutritional data of altogether 186 children in 2013 and 556 children in 2016 were analyzed. The total energy and carbohydrate intake was appropriate. We observed high sugar intake in every fifth child. Protein, fat and cholesterol intake, as well as the intake of sodium, potassium and phosphorus, were high. The consumption of calcium and vitamin D was low. Water consumption was not satisfying. The present results underline the need for interventions starting early in life in order to ameliorate nutrient intake during childhood, possibly impacting long-term health outcomes.

Abstract
Table salt is the main source of sodium (Na) in the human diet. Excessive supply of Na in a diet is strongly linked to many non-communicable human diseases, such as hypertension, obesity and stomach cancer. The World Health Organization recommends that daily intake of salt in adult diets should be kept below 5 g/person/day, which corresponds to 2 g Na/person/day. However, on average, adults consume about 9-10 g/person/day, and children and young people about 7-8 g/person/day. Initiatives to reduce salt intake include modifications of food composition in collaboration with the food industry, education of consumers, salt marking on foodstuff labels and taxation of salt. A need also exists to educate society so that they choose low-sodium products. In view of the food technology and amount of salt intake, the most important and the easiest change to make is to reduce the content of salt in baked goods. This paper analyses the results of surveys regarding strategies to reduce salt content in food products and considers multifaceted initiatives to reduce salt intake as a possible efficient method of improving the population's health status.

Abstract
This study aims at investigating the anthropometric status and food consumption patterns of children in the United Arab Emirates (UAE) and assessing their adherence to nutrient and dietary recommendations. It is a population-based cross-sectional survey of 690 children (4-12.9 years), from 3 major Emirates. Socio-demographic and anthropometric characteristics were collected. Dietary intakes were assessed using the 24-hour recall approach. Of the total sample, 4% were stunted, 8% were wasted and 28% were overweight/obese. A third of participating children consumed above the Estimated Energy Requirement, while the majority's intakes carbohydrate, total fat, and protein were within the recommendations; whereas over 70% and 90% of participants consumed above the WHO daily limits of free sugars and saturated fats, respectively. Inadequate intakes of linoleic acid (36% of children), alpha-linolenic acid (91%) and dietary fiber (100%) were observed. All children failed to meet the recommendation for vitamin D and considerable proportions had inadequate intakes of vitamin A, calcium, zinc, folate, and magnesium. Compared with the American Heart Association/American Academy of Pediatrics recommendations, low dietary adherence was noted for fruits (9%), vegetables (4%), and milk/dairy (14%). These findings may be used in the development of nutritional policies aimed at improving the diets of children in the UAE.

Agreement between 24-hour urine and 24-hour food recall in measuring salt intake in primary school children in Australia. Nutr J 2022; 21:68. [PMCID: PMC9664040 DOI: 10.1186/s12937-022-00823-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Accepted: 11/08/2022] [Indexed: 11/16/2022] Open
Abstract
Abstract
Background
Monitoring salt consumption in children is essential for informing and implementing public health interventions to reduce children’s salt intake. However, collection of 24-hour urines, considered as the most reliable approach, can be especially challenging to school children. This study aimed to assess the agreement between 24-hour urine (24hrU) and 24-hour food recall (24hrFR) in: (1) estimating salt intake in children; (2) classifying salt intakes above the recommended upper level set for children, and; (3) estimating change in mean salt intake over time.
Methods
This study utilised data from two cross-sectional surveys of school children aged 8 to 12 years living in the state of Victoria, Australia. A single 24hrU and 24hrFR were collected from each participant. Suspected inaccurate urine collections and implausible energy intakes were excluded based on pre-defined criteria. The agreement between the two methods was assessed using Bland-Altman methodology, the intraclass correlation coefficient (ICC), and the kappa statistic. The difference between the measured change in salt intake over time using 24hrU and 24hrFR was derived using mixed effects linear regression analysis.
Results
A total of 588 participants provided a 24hrU and 24hrFR. Overall, there was no meaningful difference in mean estimated salt intake between the two methods (− 0.2 g/day, 95% CI − 0.5 to 0.1). The Bland-Altman plot showed wide 95% limits of agreement (− 7.2 to 6.8). The ICC between the two methods was 0.13 (95% CI 0.05 to 0.21). There was poor interrater reliability in terms of classifying salt intake above the recommended upper level for children, with an observed agreement of 63% and kappa statistic of 0.11. The change in mean salt intake over time was 0.2 g/day (− 0.4 to 0.7) based on 24hrU, and 0.5 g/day (− 0.0 to 1.1) based on 24hrFR, with a difference-in-differences of 0.4 g/day (− 0.3 to 1.1).
Conclusions
24hrFR appears to provide a reasonable estimate of mean salt intake as measured by 24hrU in Australian school children. However, similar to previous observations in adults, and of studies exploring other alternative methods for estimating salt intake, 24hrFR is a poor predictor of individual-level salt intake in children.

Salt taste threshold and contributory factors of chronic kidney disease patients: a cross-sectional study. Int Urol Nephrol 2022; 55:1211-1218. [PMID: 36318407 DOI: 10.1007/s11255-022-03403-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Accepted: 10/15/2022] [Indexed: 11/07/2022]
Abstract
PROPOSE High salt intake, correlated with high salt taste threshold, may accelerate renal injury in chronic kidney disease (CKD) patients. However, few studies have focused on factors that influence salt taste threshold. Therefore, we aimed to identify factors that influence the salt taste threshold of CKD patients, to provide more precise salt restriction recommendations in dietary therapy. METHODS Between April 2016 and March 2019, we measured the salt taste threshold of 1019 CKD patients, aged 22-78 years, from 52 hospitals across southwestern China, and then we performed a cross-sectional study. RESULTS The mean salt taste threshold was 0.37 ± 0.16% NaCl. There were 115 (11.3%), 670 (65.7%), and 234 (23.0%), respectively, patients who had low (≤ 0.1% NaCl), medium (0.1-0.4% NaCl), and high (> 0.4% NaCl) salt taste thresholds. One-way ANOVA and regression results revealed that sex (male), age, decreased estimated glomerular filtration rate, and absence of salt restriction were factors that influenced CKD groups with high salt taste threshold. CONCLUSION We found an independent correlation between contributory factors including sex, age, eGFR, and salt restriction behavior of subjects with the salt taste threshold of CKD patients. Our findings also offer insights on salt taste thresholds that could be useful for clinicians advising salt restriction to impair the salt taste sensitivity of the corresponding populations.

Hypertension and Associated Risk Factors among Children with Intellectual Disability: A Cross-Sectional Study. Nutrients 2022; 14:nu14153127. [PMID: 35956301 PMCID: PMC9370698 DOI: 10.3390/nu14153127] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 07/26/2022] [Accepted: 07/27/2022] [Indexed: 12/02/2022] Open
Abstract
To investigate the prevalence of hypertension and associated risk factors in Chinese children with intellectual disability, a cross-sectional study was conducted in a sample of 558 children with intellectual disability aged 6–18 years in Hong Kong, and 452 (81.0%) with valid data were included in the data analysis. Blood pressure was measured according to a standard protocol. Hypertension was defined using the age-, gender-, and height-specific classification criteria recommended by the 2018 Chinese Guidelines for Children. Multivariate and hierarchical logistic regression was fitted to examine the associations of hypertension with potential risk factors. Overall, 31.4% of the participants were classified as having hypertension. Obese children were more likely to develop hypertension than non-obese children (adjusted OR = 2.77, 95% CI: 1.28, 5.99, p = 0.010). A paternal education of college or above and a paternal occupation of clerks, sales representatives, and workers were also associated with an increased risk of hypertension. The prevalence of hypertension is high among Chinese children with intellectual disability. Obesity was the strongest risk factor. Further longitudinal studies are warranted to confirm our findings. Nevertheless, preventions against obesity are promising to receive doubled benefits in reducing both obesity and hypertension, given its strong relationship with hypertension in this special population.

Twenty-Four-Hour Urinary Sodium Excretion Predicts Therapeutic Effectiveness of Oral Rehydration Saline in Pediatric Vasovagal Syncope. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9070992. [PMID: 35883976 PMCID: PMC9321383 DOI: 10.3390/children9070992] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Revised: 06/24/2022] [Accepted: 06/27/2022] [Indexed: 11/29/2022]
Abstract
The study was designed to explore whether 24-hour urinary sodium excretion could predict the therapeutic effectiveness of oral rehydration saline in pediatric cases of vasovagal syncope. Eighty children suffering from vasovagal syncope with oral rehydration saline treatment in Department of Pediatrics, Peking University First Hospital, China, were recruited into the study. They were followed up for 3 (2, 3) months after treatment. Pre-treatment demographic, clinical, head-up tilt test-based hemodynamic and laboratory variables were compared between responders and non-responders. After univariate analysis, variables with p value < 0.05 in the comparison between responders and non-responders were further analyzed by binary logistic regression analysis. Receiver operating characteristic (ROC) curve was conducted to assess the value in predicting effectiveness of oral rehydration saline treatment. The results showed that 33 cases were responders, and 47 were non-responders. Blood sodium (138 ± 2 mmol/L vs. 139 ± 2 mmol/L, p < 0.05) and pre-treatment 24-hour urinary sodium excretion (74 ± 29 mmol/24 h vs. 109 (93, 141) mmol/24 h, p < 0.001) were lower in responders than in non-responders. The baseline 24-hour urinary sodium excretion was positively correlated to the duration from tilting to the positive response appearance in head-up tilt test (r = 0.289, p < 0.01). The cut-off value of baseline 24-hour urinary sodium excretion of the therapeutic effectiveness of oral rehydration saline on vasovagal syncope cases was 83 mmol/24 h, yielding a sensitivity of 87% and a specificity of 73% with AUC of 0.842 (p < 0.001). In conclusion, 24-hour urinary sodium excretion could be a useful biomarker to predict the therapeutic response to oral rehydration saline in pediatric cases of vasovagal syncope.

Kikuchi T. Pediatric hypertension based on Japanese Society of Hypertension Guidelines (JSH 2019) with actual school blood pressure screening data in Japan. Clin Exp Pediatr 2022; 65:283-290.

Abstract
Blood pressure (BP) in children and adolescents is associated with their growth. BP is most strongly associated with height during height gain and with degree of obesity after reaching final height. BP in childhood and adolescence is correlated with BP in adulthood. The pathophysiology of pediatric essential hypertension is associated with obesity, excess salt intake, and a low birth weight. The common causes of pediatric secondary hypertension are renal parenchymal and renovascular diseases. The significance of diagnosing pediatric hypertension involves detecting secondary hypertension and preventing organ damage due to hypertension as well as tracking essential hypertension in adulthood. Appropriate BP measurement procedures are required for diagnosing pediatric hypertension. The inflatable bladder of an appropriately sized cuff should exceed 40% of the arm circumference. BP measurements should be performed consecutively at least 3 times using an appropriately sized cuff. The diagnosis of hypertension requires that all BP values measured on 3 or more occasions be above the reference value. The criteria for pediatric hypertension are determined based on the distribution of BP in healthy children and adolescents, with values above the 95th percentile of normal representing hypertension. Japanese criteria define pediatric hypertension as ≥120/70 mmHg for preschool children, ≥130/80 mmHg for 1st-3rd graders, ≥135/80 mmHg for 4th-6th graders, ≥140/85 mmHg for 7th-9th grade boys, ≥135/80 mmHg for 7th-9th grade girls, and ≥140/85 mmHg for senior high school boys and girls. The prevalence of Japanese pediatric hypertension was 0.9% based on proper measurement protocols. The basis of managing pediatric essential hypertension is healthy lifestyle modifications. Pharmacotherapy is indicated for persistent hypertension, symptomatic hypertension, secondary hypertension, the development of target organ damage, the presence of chronic kidney disease, and diabetes mellitus. Screening for pediatric hypertension is important; therefore, BP should be routinely measured in children and adolescents.

Abstract
Background The transition from a predominantly milk-based diet to a diverse family diet is a window of opportunity for optimal child growth and development. Objectives The study aims to examine the nutritional status and food-consumption patterns of children under 4 y of age in the United Arab Emirates (UAE) and their adherence to nutrient and dietary recommendations. Methods A population-based cross-sectional survey of 525 children aged 0-47.9 mo was conducted in 3 major emirates: Abu Dhabi, Dubai, and Sharjah. Anthropometric measurements were obtained, and dietary assessment was conducted using the 24-h dietary recall approach. Usual intakes of energy, macronutrient, and micronutrients, including from supplements, were assessed using PC-SIDE software. Adherence to food-group recommendations was evaluated based on the American Heart Association/American Academy of Pediatrics dietary guidelines. Results Among 0-4-y-old children, 10% were stunted, 6% were wasted, 17% were at risk of overweight, 5% were overweight, and 3% were obese. The contribution of sweets and sugar sweetened beverages to energy intake increased from 5% in 6-11.9-mo-old children to 17% in 36-47.9-mo-old children. Compared with dietary guidelines, the lowest adherence was for fruit (13-18%) and vegetables (7-12%), while protein was within the recommendations, and 92% and 89% of children (aged 24 to 35.9 mo and 36 to 47.9 mo, respectively) had high intakes of saturated fat. Almost all toddlers failed to meet the Adequate Intake for fiber. The proportions of children exceeding the free-sugar upper limit increased from 10.6% in infants (0-5.9 mo) to 56.7% in toddlers (12- 23.9 mo). Micronutrient inadequacies were observed, particularly for calcium, zinc, folate, and vitamins A and D. Conclusions This study suggests a triple burden of malnutrition among infants and young children in the UAE. Results call for national nutrition intervention strategies aimed at improving dietary quality in the pediatric population.

Abstract
BACKGROUND The objective of this study was to examine the association of an integrated model (composed of retinal arteriolar caliber, height, and sex) with blood pressure (BP) among a group of Chinese children, and assess the predictive value of the integrated model for childhood hypertension. METHODS This study included 1460 candidates aged 12.634 ± 0.420 years. Height, weight, waist circumference, and BP were obtained and ophthalmological measurements were taken. The computer-imaging program (IVAN, University of Wisconsin, Madison, WI) was used to measure calibers of retinal vessels. Receiver-operating characteristic curve (ROC) analyses were performed to assess the accuracy of the integrated model as a diagnostic test of elevated BP in children. RESULTS The accuracy of the integrated model (assessed by area under the curve) for identifying elevated BP was 0.777 (95% confidence interval: 0.742-0.812). The optimal threshold of the integrated model for defining hypertension was 0.153, and the calculation formula for the specific predictive risk was: Logit (p/1 - p) = -5.666 - 0.261 × retinal arteriolar caliber + 0.945 × sex + 0.438 × height. In identifying elevated BP, the sensitivity and specificity were 0.711 and 0.736, respectively. CONCLUSIONS The model containing eye message is a comprehensive and relatively effective index to identify elevated BP in 12-year-old children, which can offer assistance to further understand childhood microcirculation disease. IMPACT We firstly incorporated retinal vascular diameter, sex, and height into one integrated model to identify hypertension in 12-year-old children. The current discrimination of hypertension in children is difficult. There have been some studies to simplify the diagnosis of children's hypertension, but they were limited to anthropometric measurements. We proposed a composed model containing microcirculation information to predict childhood hypertension. Based on the knowledge that microcirculation is not only a means to study the manifestations but also early pathogenic correlates of hypertension, the combined model containing microcirculation message as a method may provide new insights into the diagnosis of childhood hypertension.

Abstract
Children are consuming less healthy foods, and this eating behaviour exposes the child to greater Na intake. The association between family, maternal and child characteristics with Na intake by children aged 13-35 months was evaluated. A study carried out with retrospective data on 1,185 children from the Brisa cohort. The children's dietary Na intake was assessed by a 24-h diet recall survey. Values ≥ 1200 mg were considered excessive intake. The association between Na intake and independent variables was assessed by a three-level logistic hierarchical regression model. Variables with P-value < 0·05 were retained in the model. Most children were male (51·2 %), eutrophic (63·2 %) and not exclusively breast-feeding (EBF) for 6 months (58·4 %). The average Na intake was 925 mg (±410·4). The prevalence of excessive Na intake was 18·5 % and was associated with the variables children of younger mothers (< 20 years old OR = 4·04, 95 % CI 1·64, 9·99; ≥ 20 to < 35 years old OR = 2·48, 95 % CI 1·10, 5·63), having four or more children (OR = 2·51, 95 % CI 1·29, 4·89), lower family income (≥ 1 and < 3 minimum wages OR = 0·60, 95 % CI 0·39, 0·93; ≥ 3 minimum wages OR = 0·50, 95 % CI 0·30, 0·82) and not being EBF until 6 months (OR = 1·64, 95 % CI 1·14, 2·34). The average Na intake of children was higher than the recommendation for adequate intake, pointing to a high consumption of this micronutrient in the first years of life. Excessive Na intake seems to be linked to unfavourable socio-economic conditions. Avoiding early weaning is the only possible intervention in this scenario.

Abstract
BACKGROUND Urine sodium and potassium are used as surrogate markers for dietary consumption in adults with hypertension, but their role in youth with hypertension and their association with components of the renin-angiotensin-aldosterone system (RAAS) are incompletely characterized. Some individuals with hypertension may have an abnormal RAAS response to dietary sodium and potassium intake, though this is incompletely described. Our objective was to investigate if plasma renin activity and serum aldosterone are associated with urine sodium and potassium in youth referred for hypertensive disorders. METHODS This pilot study was a cross-sectional analysis of baseline data from 44 youth evaluated for hypertensive disorders in a Hypertension Clinic. We recorded urine sodium and potassium concentrations normalized to urine creatinine, plasma renin activity, and serum aldosterone and calculated the sodium/potassium (UNaK) and aldosterone/renin ratios. We used multivariable generalized linear models to estimate the associations of renin and aldosterone with urine sodium and potassium. RESULTS Our cohort was diverse (37% non-Hispanic Black, 14% Hispanic), 66% were male, and median age was 15.3 years; 77% had obesity and 9% had a secondary etiology. Aldosterone was associated inversely with urine sodium/creatinine (β: -0.34, 95% CI -0.62 to -0.06) and UNaK (β: -0.09, 95% CI -0.16 to -0.03), and adjusted for estimated glomerular filtration rate and serum potassium. CONCLUSIONS Higher serum aldosterone levels, but not plasma renin activity, were associated with lower urine sodium/creatinine and UNaK at baseline in youth referred for hypertensive disorders. Further characterization of the RAAS could help define hypertension phenotypes and guide management. A higher resolution version of the Graphical abstract is available as supplementary information.

Recommendations on Complementary Feeding as a Tool for Prevention of Non-Communicable Diseases (NCDs)-Paper Co-Drafted by the SIPPS, FIMP, SIDOHaD, and SINUPE Joint Working Group. Nutrients 2022; 14:nu14020257. [PMID: 35057438 PMCID: PMC8778394 DOI: 10.3390/nu14020257] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 12/30/2021] [Accepted: 01/05/2022] [Indexed: 12/30/2022] Open
Abstract
Adequate and balanced nutrition is essential to promote optimal child growth and a long and healthy life. After breastfeeding, the second step is the introduction of complementary feeding (CF), a process that typically covers the period from 6 to 24 months of age. This process is, however, still highly controversial, as it is heavily influenced by socio-cultural choices, as well as by the availability of specific local foods, by family traditions, and pediatrician beliefs. The Società Italiana di Pediatria Preventiva e Sociale (SIPPS) together with the Federazione Italiana Medici Pediatri (FIMP), the Società Italiana per lo Sviluppo e le Origine della Salute e delle Malattie (SIDOHaD), and the Società Italiana di Nutrizione Pediatrica (SINUPE) have developed evidence-based recommendations for CF, given the importance of nutrition in the first 1000 days of life in influencing even long-term health outcomes. This paper includes 38 recommendations, all of them strictly evidence-based and overall addressed to developed countries. The recommendations in question cover several topics such as the appropriate age for the introduction of CF, the most appropriate quantitative and qualitative modalities to be chosen, and the relationship between CF and the development of Non-Communicable Diseases (NCDs) later in life.

Abstract
Background Determining high blood pressure in childhood is an important step to reduce the risk of occurrence of high blood pressure-related diseases in adulthood. Aims This study aimed to assess the association of blood pressure with dietary intake, physical activity, and anthropometric measurements in Turkish adolescents. Patients and Methods This cross-sectional study included 370 students (202 females, 168 males) aged 14 to 18 years from one private and one public school in Kayseri, Turkey. Some anthropometric measurements and 24-hour dietary recall of the students were obtained. Their blood pressures were measured, and the International Physical Activity Questionnaire and the Mediterranean Diet Quality Index (KIDMED) were used. Results The body mass index (BMI) mean and waist/height ratio of the hypertensive group were significantly higher than those of the prehypertensive group, whereas their daily potassium, calcium, and magnesium intakes were significantly lower than those of the normotensive group. The percentage of individuals with very low diet quality was higher in the hypertensive group than in the normotensive group (P > 0.05). The percentage of participants with sufficient physical activity was higher in the normotensive group than in the prehypertensive and hypertensive groups. Conclusion Factors such as high BMI and waist/height rates; low calcium, magnesium, and potassium intakes with diet; insufficient physical activity; and low quality of diet might cause an increase in the blood pressure.

Abstract
High salt intake is known as a risk factor of childhood obesity. As family members share not only genes but also their diet habit, parents' salt intake may affect to their children's obesity. In this study, we investigated correlations between childhood obesity and parents' or children's sodium intakes based on a nationwide survey data. From the Korean National Health and Nutrition Examination Survey data from 2014 to 2017, 802 boys and 657 girls aged 10-18 years, and their parents were included. BMI z-score and 24-hour urinary sodium excretion, which is estimated through Tanaka's equation, were used to examine associations between obesity and sodium intakes. The BMI status and the prevalence of obesity between children and their parents showed strong positive correlations in both sexes (all p < 0.001). The urinary sodium excretion between children and their parents showed positive correlations in both sexes (all p < 0.05). Children with higher urinary sodium excretion showed higher BMI (in both sexes, p < 0.001) and higher parental obesity compared to those with lower urinary sodium excretion, however, statistical significances of the latter relationship were varied by sex. In conclusion, our study suggests close relationship between childhood obesity and their sodium intakes, which also correlate well with parental BMIs and diet behavior. Therefore, parental education and active participation could be crucial in regulating childhood obesity.

Abstract
This cross-sectional study aimed to assess 24-h urinary sodium and potassium excretion in children and the relationships with their family excretion. Using the baseline data of a randomized trial conducted in three cities of China in 2018, a total of 590 children (mean age 8.6 ± 0.4 years) and 1180 adults (mean age 45.8 ± 12.9 years) from 592 families had one or two complete 24-h urine collections. The average sodium, potassium excretion and sodium-to-potassium molar ratio of children were 2180.9 ± 787.1 mg/d (equivalent to 5.5 ± 2.0 g/d of salt), 955.6 ± 310.1 mg/d and 4.2 ± 1.7 respectively, with 77.1% of the participants exceeding the sodium recommendation and 100% below the proposed potassium intake. In mixed models adjusting for confounders, every 1 mg/d increase in sodium excretion of adult family members was associated with a 0.11 mg/d (95% CI: 0.06 to 0.16, p < 0.0001) increase in sodium excretion of children. The family-child regression coefficient corresponds to 0.20 mg/d (95% CI: 0.15 to 0.26, p < 0.0001) per 1 mg/d in potassium and to 0.36 (95% CI: 0.26 to 0.45, p < 0.0001) in sodium-to-potassium molar ratio. Children in China are consuming too much sodium and significantly inadequate potassium. The sodium, potassium excretion and sodium-to-potassium ratio of children are associated with their family excretions in small to moderate extent. Efforts are warranted to support salt reduction and potassium enhancement in children through comprehensive strategies engaging with families, schools and food environments.

Abstract
Many consumers are concerned about the high levels of salt intake owing to the accompanied risk of chronic diseases. Due to this dietary concern, the food industry has recommended the reduction of salt content in many products. However, the addition of salt to meat products improves their quality and sensory properties, including saltiness, color, juiciness, and texture. Because quality deteriorations could induce decreased sensory scores owing to salt reductions, the challenges involved in improving the quality of reduced-salt meat products have been addressed. During the development of low-salt meat products, it is important to reduce sodium content and address the problems that arise with this reduction. Modified salt, organic acids, amino acids, nucleotides, hydrocolloids, high-pressure, ultrasound, electric pulsed field, and irradiation have been suggested as strategies to replace or reduce sodium content, and sensory scores could be improved by these strategies. Therefore, when developing a low-salt meat product, several perspectives must be considered and the latest technologies that could resolve this problem should be adopted.

Abstract
PURPOSE The World Health Organization recommends reduction of salt intake to < 5 g/day and the use of iodized salt to prevent iodine deficiency states. A high prevalence of excess salt consumption and an inadequate iodine intake has been previously shown in an Italian pediatric population. It was appropriate, therefore, to analyse in the same population the relationship occurring between salt consumption and iodine intake. METHODS The study population was made of 1270 children and adolescents. Estimates of salt consumption and iodine intake were obtained by measuring 24 h urinary sodium and iodine excretion. RESULTS The iodine intake increased gradually across quartiles of salt consumption independently of sex, age and body weight (p < 0.001). Median iodine intake met the European Food Safety Authority adequacy level only in teenagers in the highest quartile of salt consumption (salt intake > 10.2 g/day). We estimated that approximately 65-73% of the total iodine intake was derived from food and 27-35% from iodized salt and that iodized salt made actually only 20% of the total salt intake. CONCLUSION In this pediatric population, in face of an elevated average salt consumption, the use of iodized salt was still insufficient to ensure an adequate iodine intake, in particular among teenagers. In the perspective of a progressive reduction of total salt intake, the health institutions should continue to support iodoprophylaxis, in the context of the national strategies for salt reduction. In order for these policies to be successful, in addition to educational campaigns, it is needed that the prescriptions contained in the current legislation on iodoprophylaxis are made compelling through specific enforcement measures for all the involved stakeholders.

Abstract
CONTEXT A congenital solitary functioning kidney (cSFK) is a common developmental defect that predisposes to hypertension and chronic kidney disease (CKD) as a consequence of hyperfiltration. Every urologist takes care of patients with a cSFK, since some will need lifelong urological care or will come with clinical problems or questions to an adult urologist later in life. OBJECTIVE We aim to provide clear recommendations for the initial clinical management and follow-up of children with a cSFK. EVIDENCE ACQUISITION PubMed and EMBASE were searched to identify relevant publications, which were combined with guidelines on related topics and expert opinion. EVIDENCE SYNTHESIS Initially, cSFK diagnosis should be confirmed and risk factors for kidney injury should be identified using ultrasound. Although more research into early predictors of kidney injury is needed, additional congenital anomalies of the kidney or urinary tract and absence of compensatory kidney hypertrophy have repeatedly been associated with a worse prognosis. The role of voiding cystourethrography and antibiotic prophylaxis remains controversial, and is complicated by the exclusion of children with a cSFK from studies. A yearly follow-up for signs of kidney injury is recommended for children with a cSFK. As masked hypertension is prevalent, annual ambulatory blood pressure measurement should be considered. During puberty, an increasing incidence of kidney injury is seen, indicating that long-term follow-up is necessary. If signs of kidney injury are present, angiotensin converting enzyme inhibitors are the first-line drugs of choice. CONCLUSIONS This overview points to the urological and medical clinical aspects and long-term care guidance for children with a cSFK, who are at risk of hypertension and CKD. Monitoring for signs of kidney injury is therefore recommended throughout life. Large, prospective studies with long-term follow-up of clearly defined cohorts are still needed to facilitate more risk-based and individualized clinical management. PATIENT SUMMARY Many children are born with only one functioning kidney, which could lead to kidney injury later in life. Therefore, a kidney ultrasound is made soon after birth, and other investigations may be needed as well. Urologists taking care of patients with a solitary functioning kidney should realize the long-term clinical aspects, which might need medical management.

Abstract
The contribution of high sodium intake to hypertension and to the severity of immune-mediated diseases is still being heatedly debated in medical literature and in the lay media. This review aims to demonstrate two conflicting views on the topic, with the first part citing the detrimental effects of excessive salt consumption. Sodium plays a central role in volume and blood pressure homeostasis, and the positive correlation between sodium intake and blood pressure has been extensively researched. Despite the fact that the average of global daily salt consumption exceeds recommendations of international associations, health damage from excessive salt intake is still controversial. Individual differences in salt sensitivity are in great part attributed to this contradiction. Patients suffering from certain diseases as well as other vulnerable groups-either minors or individuals of full age-exhibit more pronounced blood pressure reduction when consuming a low-sodium diet. Furthermore, findings from the last two decades give insight into the concept of extrarenal sodium storage; however, the long-term consequences of this phenomenon are lesser known. Evidence of the relationship between sodium and autoimmune diseases are cited in the review, too. Nevertheless, further clinical trials are needed to clarify their interplay. In conclusion, for salt-sensitive risk groups in the population, even stricter limits of sodium consumption should be set than for young, healthy individuals. Therefore, the question raised in the title should be rephrased as follows: "how much salt is harmful" and "for whom is elevated salt intake harmful?"

Abstract
BACKGROUND The aim of the study is to identify the effect of salt intake and diabetes itself on blood pressure (BP) profile and microalbuminuria in children with type one diabetes mellitus (T1DM). Our hypothesis is that higher amount of salt consumption and/or hyperglycemia may impair blood pressure pattern in children with T1DM. METHODS This cross-sectional study included 84 children and adolescents with T1DM (62% females, age 13.9 ± 3.2 years, disease duration 7.3 ± 3.1 years, 43% poorly controlled diabetes) and 54 aged- and sex-matched healthy children with an adequately collected 24-h urine samples. Urine sodium, creatinine, and microalbumin were measured and salt intake was assessed on the basis of sodium excretion in 24-h urine. Blood pressure profile of the children with T1DM was evaluated with 24-h ambulatory blood pressure monitoring. RESULTS Compared to the children with well-controlled diabetes, children with poorly controlled diabetes had significantly higher standard deviation scores (SDS) of nighttime systolic BP (0.22 ± 1.28 vs - 0.87 ± 0.76, p = 0.003) and lower dipping in diastole (13.4 ± 5.9 vs 18.4 ± 8.1, p = 0.046). Among T1DM group, children with the highest quartile of salt intake had higher nighttime systolic and diastolic BP-SDS (0.53 ± 1.25 vs - 0.55 ± 0.73, p = 0.002 and 0.89 ± 1.19 vs 0.25 ± 0.63, p = 0.038, respectively) and lower dipping in systole compared to their counterparts (7.7 ± 5.0 vs 11.5 ± 6.1, p = 0.040). High averaged HbA1c was independently associated with higher both daytime and nighttime systolic BP-SDS (p = 0.010, p < 0.001) and nighttime diastolic BP-SDS (p = 0.001), and lower diastolic dipping (p = 0.001). High salt intake was independently associated with higher nighttime systolic BP-SDS (p = 0.002) and lower systolic dipping (p = 0.019). A 24-h MAP-SDS was the only independent risk factor for microalbuminuria (p = 0.035). CONCLUSION Beside poor diabetic control, high salt consumption appears to be an important modifiable risk factor for impaired BP pattern, which contributes to the development of diabetic kidney disease in children with T1DM.

Abstract
OBJECTIVE Test the efficacy and perceived effectiveness of nutrition labels on children's menus from a full-service chain restaurant in an online study. DESIGN Using a between-groups experiment, parents were randomised to view children's menus displaying one of five children's nutrition labelling conditions: (i) No Nutrition Information (control); (ii) Calories Only; (iii) Calories + Contextual Statement (CS); (iv) Calories, Sodium + CS; or (v) Calories and Sodium in Traffic Lights + CS. Parents hypothetically ordered up to one entrée, side, beverage and dessert for their child, then rated and ranked all five labelling conditions on the level of perceived effectiveness. SETTING Online survey. PARTICIPANTS 998 parents with a 3-12 year old child. RESULTS Parents exposed to menus displaying 'Calories, Sodium + CS' selected significantly fewer calories 'overall' (entrées + side + dessert + beverage) compared to parents exposed to the control condition (-53·1 calories, P < 0·05). Parents selected 'entrees' with significantly fewer calories and lower sodium when exposed to menus with 'Calories + CS' (-24·3 calories, P < 0·05); 'Calories, Sodium + CS' (-25·4 calories, -56·1 mg sodium, P < 0·05 for both); and 'Calories and Sodium in Traffic Lights + CS' (-29·1 calories, -58·6 mg sodium, P < 0·05 for both). Parents exposed to menus with 'Calories, Sodium + CS' and 'Calories and Sodium in Traffic Lights + CS' were more likely to notice and understand nutrition information compared to other nuntrition labelling conditions. Parents perceived the menu with 'Calories and Sodium in Traffic Lights + CS' as most effective (P < 0·05). CONCLUSIONS Menus disclosing calories, sodium and a contextual statement increased the proportion of parents who noticed and understood nutrition information, and resulted in parents selecting lower calorie and sodium entrées for their children in the hypothetical purchase task.

Abstract
The first 1000 days of life represent a critical window for infants' and children's development. Overweight and insulin resistance, at the basis of non-communicable diseases (NCDs), are linked to various risk factors that begin in childhood, including children's diet. Italian data on infants' and children's dietary habits show higher intake of proteins, simple sugars, unhealthy fats and salt than recommended, while the iron intake is below requirement. We reviewed current literature analyzing observational studies, meta-analysis, systematic review and randomized clinical trials of the last 10 years (from 2009) on nutrition in developmental age, providing some few rules to abide by. Exclusive breastfeeding is recommended by World Health Organization for the first 6 months of life and it should be continued alongside the complementary feeding period until 12 months, or even afterward. Complementary feeding should not be started before the 17th week of age with energetically adequate foods, paying attention to limit protein intake and favoring iron-rich foods. Intake of simple sugars should be limited or avoided at all; it has been demonstrated that substituting sugar-sweetened beverages with water decreases body fatness development in adolescence. Quality of the ingested fats is more important than their quantity: polyunsaturated fatty acids should be preferred. Sodium intake should be limited in the first 24 months of life, as first prevention measure of arterial hypertension later in adulthood. Healthy eating habits are the first important step toward the prevention of NCDs.

Abstract
Hypertension is a condition with increased risk for subsequent adverse events, and treatment of hypertension is prescribed for primary prevention of adverse events. Primordial prevention is a concept that precedes primary prevention and focuses on risk factor prevention. Primordial prevention of hypertension consists of strategies to maintain blood pressure in a normal range and prevent development of elevated blood pressure or hypertension. Childhood is a period in which primordial prevention could be effective and if sustained throughout childhood could contribute to a healthier young adulthood. Targets for primordial prevention in childhood include preventing and reducing childhood obesity, achieving an optimal diet that includes avoiding excessive salt consumption, and removing barriers to physical activity and healthy sleep throughout childhood. Primordial prevention also includes the prenatal period wherein some maternal conditions and exposures are associated with higher blood pressure in child offspring.

Abstract
There are no published harmonized nutrient reference values for the complementary feeding period. The aim of the study was to develop proposals on adequate and safe intake ranges of micronutrients that can be applied to dietary guidance and menu planning. Dietary intake surveys from 6 populous countries were selected as pertinent to the study and reviewed for data on micronutrients. The most frequently underconsumed micronutrients were identified as iron, zinc, calcium, magnesium, phosphorus, potassium, and vitamins A, B6, B12, C, D, E, and folate. Key published reference values for these micronutrients were identified, compared, and reconciled. WHO/FAO values were generally identified as initial nutrient targets and reconciled with nutrient reference values from the Institute of Medicine and the European Food Standards Authority. A final set of harmonized reference nutrient intake ranges for the complementary feeding period is proposed.

Abstract
In recent times, the traditional nephrocentric, two-compartment model of body sodium has been challenged by long-term sodium balance studies and experimental work on the dermal interstitium and endothelial surface layer. In the new paradigm, sodium can be stored without commensurate water retention in the interstitium and endothelial surface layer, forming a dynamic third compartment for sodium. This has important implications for sodium homeostasis, osmoregulation and the hemodynamic response to salt intake. Sodium storage in the skin and endothelial surface layer may function as a buffer during periods of dietary depletion and excess, representing an extra-renal mechanism regulating body sodium and water. Interstitial sodium storage may also serve as a biomarker for sodium sensitivity and cardiovascular risk, as well as a target for hypertension treatment. Furthermore, sodium storage may explain the limitations of traditional techniques used to quantify sodium intake and determine infusion strategies for dysnatraemias. This review is aimed at outlining these new insights into sodium homeostasis, exploring their implications for clinical practice and potential areas for further research for paediatric and adult populations.

Abstract
Background Accurate assessments of sodium intake in children are important for the early prevention of cardiovascular disease. There is currently no accurate simple and feasible sodium intake approach for children. This study intends to validate the accuracy of 24‐hour urinary sodium excretion (UNaV) estimation in children using 3 common formulas: the Kawasaki, INTERSALT (International Cooperative Study on Salt, Other Factors, and Blood Pressure), and Tanaka formulas. Methods and Results A hospital‐based child population in China was enrolled in the study and completed 24‐hour urine sample collection. Concentrations of sodium, potassium, and creatinine in 24‐hour urine and spot urine samples were measured. Mean difference as well as absolute and relative differences and misclassification between estimation and measurement of UNaV with 3 commonly used formulas were compared and analyzed. A total of 129 participants aged 5 to 16 years were eligible for analysis. Mean measured UNaV was 2694.9 mg/day. Mean differences between estimated and measured UNaV by the Kawasaki, INTERSALT, and Tanaka formulas were 2367.6, 26.4, and 258.8 mg/day, respectively. Proportions of relative differences of over 40% for the Kawasaki, INTERSALT, and Tanaka formulas were 79.8%, 34.9%, and 38.5%, respectively. Misclassification rates were 73.1% for Kawasaki, 69.0% for INTERSALT, and 62.4% for Tanaka at the individual level. Conclusions The results from our study do not support estimation of UNaV for children by the Kawasaki, INTERSALT, and Tanaka formulas using single spot urine samples because of the potential risk for misclassification at the individual level.

Abstract
OBJECTIVE Obesity in the United Kingdom and the Republic of Ireland is rising, as is the frequency of eating out in restaurants. The aim of this study was to investigate the nutritional quality of children's menus in restaurants. DESIGN Cross-sectional review of menus aimed at children from 20 popular chain restaurants in the United Kingdom and Ireland. MAIN OUTCOME MEASURES Total energy, fat, saturated fat, and salt were collected from every food item on the menu in each restaurant. All potential meal combinations were created. A total of 39,266 meals were analysed. ANALYSIS Meals were compared with UK nutritional guidelines. Meals from fast food and full-service restaurants and main meals and meal deals were compared. RESULTS The average meal for younger children (aged 2-5 years) contained 609 ±117 kcal, and for older children (6-12 years) 653 ± 136 kcal compared with guidelines of 364 and 550 kcal, respectively. A total of 68% of younger children's and 55% of older children's meals contained more total fat than recommended and more than 4 times the amount of saturated fat. Fast food restaurant meals contained less energy, fat, and salt than did full-service restaurants, and meal deals were less likely to meet dietary guidelines than were main meals alone. CONCLUSION AND IMPLICATIONS Eating in chain restaurants, in particular meal deals, does not contribute positively to the diet of children in the United Kingdom and Ireland.

Abstract
Background High salt consumption has contributed to the rise of noncommunicable diseases around the world. The application of mobile health (mHealth) technologies has witnessed rapid growth in recent years. However, evidence to support mHealth interventions to confront the challenge of salt reduction has not yet been critically reviewed. Objective The aim of this study was to identify, characterize, and evaluate mHealth interventions aimed at salt reduction across the world. Methods A systematic search of studies in English or Chinese language published from January 1, 1992 to July 31, 2017 was conducted using 4 English databases (PubMed, MEDLINE, Global Health, and Cochrane) and 3 Chinese databases (Wanfang, China Science and Technology Journal, and China National Knowledge of Infrastructure). All studies directly using mobile technologies in health care with a primary or secondary objective of reducing dietary salt consumption were included. Results A total of 1609 articles were found using the search strategy, with 11 full articles (8 English and 3 Chinese) being included for data extraction, including 11 interventional studies. Overall, few high-quality interventions were identified. Most interventions were limited by small study population sample sizes, lack of control groups, and short follow-up times, all of which were obstacles in generating long-term scalable approaches. Most interventions employed short message service as a platform for mHealth interventions, whereas some innovative mHealth technologies were also explored. Most interventions had a primary focus of improving awareness of dietary salt consumption. The outcome variables used to measure intervention effectiveness included 24-hour urinary sodium excretion, spot urine sampling, dietary records, and indirect behavior or knowledge indicators targeting salt consumption. Although most interventions displayed positive outcome results, none of them provided reliable evidence to evaluate the effectiveness of salt reduction. Conclusions Salt reduction in mHealth initiatives remains relatively unexplored; however, studies that did intervene on salt-reduction show the potential of mHealth as an effective intervention method. We provide 3 recommendations for future mHealth interventions in salt reduction—(1) increased use of new, innovative, and interactive mHealth technologies; (2) development of mHealth interventions with primary prevention measures and goals of salt reduction; and (3) large-scale, rigorously designed, and object-targeted clinical trials of mHealth interventions with appropriate quantitative outcome variables, in particular 24-hour urine sodium.

Development of a human milk concentrate with human milk lyophilizate for feeding very low birth weight preterm infants: A preclinical experimental study. PLoS One 2019; 14:e0210999.

Abstract
Breast milk is considered the gold standard nutritional resource for very low birth weight (VLBW) infants in terms of nutrients and protective factors. If mother's milk is not available, the second choice is donated and fortified human milk (HM) from the Human Milk Bank (HMB). This study hypothesized that HM could be lyophilized and used as an additive to increase the levels of macronutrients and micronutrients available to VLBW infants. This study aimed to constitute a lyophilized HM concentrate and determine the osmolality and the concentration of macronutrients and micronutrients in HM samples at “baseline” and in “HM concentrates”, analyzed immediately (HMCI), and after 3 (HMC3m) and 6 (HMC6m) months of freezing. Osmolality was verified using the freezing point osmometric method. Macronutrient quantification was performed using the MIRIS Human Milk Analyzer. Micronutrients were determined by Flame Atomic Absorption Spectrophotometry and by the automated colorimetric method. Bayesian linear mixed effect models were adjusted using OpenBUGS to estimate mean differences and 95% credibility intervals (CrI) of osmolality and of macro- and micronutrients between the types of HM samples. A comparison of dosage values showed a significant increase between HM baseline and HMCI, HMC3m, and HMC6m. Comparing HM baseline and HMCI highlighted the increase in energy content and the concentration of carbohydrates and total lipids. The Ca and P contents increased and the levels of energy, total lipids, and Cu were reduced in HMC3m compared to HMCI. Ca, Mg, K, Zn, and P increased and the levels of energy, total lipids, and Cu were reduced in HMC6m, compared to HMCI. The present study confirms the possibility of formulation and utilization of the immediate concentrate. Partial stability of HM concentrates generated from freeze-drying of donated milk do not recommend storage.

Abstract
Hypertension in childhood leads to hypertension in adult life, the strongest risk factor being obesity. This study determined the prevalence of primary hypertension and its risk factors in Grade XII learners in KwaZulu-Natal, South Africa, from March 2016 to June 2017. Weight, height, body mass index (BMI), random finger prick cholesterol and glucose, and spot urine for an albumin : creatinine ratio were measured. An average of three separate blood pressure readings taken was at least 5 minutes apart. Five hundred and sixty-four learners had weight, height, and BMI; 536 had random blood glucose; and 545 had cholesterol and random spot urine albumin : creatinine ratios measured. Prehypertension was detected in 168 (29.7%) and hypertension in 77 (13.7%) of learners. Ninety (15.9%) were overweight and 75 (13,3%) were obese. Hypercholesterolaemia was present in 58 (10.8%) and a high spot random urine albumin : creatinine ratio in 5 (1.0%). None had a high blood glucose level. Both prehypertension and hypertension in all learners showed a significant increase with increasing BMI. Six (1.0%) learners had metabolic syndrome. Female learners in other racial groups (defined as Indian, mixed race, and White learners), overweight, and obese learners showed significantly higher rates of hypercholesterolaemia. We showed overweight and obesity as risk factors for prehypertension and hypertension. This presages the need for an appropriate diet and adequate exercise in a child's school career.

Salt sensitivity of blood pressure at age 8 years in children born preterm. J Hum Hypertens 2018; 32:367-376.

Abstract
Preterm birth and low birth weight have been associated with an increased risk of hypertension; postnatal growth and dietary salt intake may contribute to these associations. In adults, the change of blood pressure (BP) in response to modifications in salt intake, i.e., salt sensitivity of BP, has been independently associated with cardiovascular disease. Little is known about salt sensitivity in children. We hypothesize that it may partly explain the association between preterm birth and higher BP in later life. We assessed salt sensitivity of BP at age 8 years in 63 preterm-born children, and explored its association with postnatal growth, sodium intake, and body composition from infancy onwards. BP was measured at baseline and after a 7-day high-salt diet. The difference in mean arterial pressure (MAP) was calculated; salt sensitivity was defined as an increase in MAP of ≥5%. Ten children (16%) showed salt sensitivity of BP, which was associated with neonatal growth restriction as well as with lower fat mass and BMI from infancy onwards. At age 8 years, children classified as salt sensitive had a lower weight-for-age SD-score (-1.5 ± 1.3 vs. -0.6 ± 1.1) and BMI (13.8 ± 1.7 vs. 15.5 ± 1.8 kg/m2) compared to their salt resistant counterparts. Sodium intake was not associated with (salt sensitivity of) BP. Salt sensitivity of BP was demonstrated in preterm-born children at age 8 years and may contribute to the development of cardiovascular disease at later age. Long-term follow-up studies are necessary to assess reproducibility of our findings and to explore clustering with other cardiovascular risk factors.

Abstract
BACKGROUND China has seen rapid increase in obesity and hypertension prevalence and fast food consumption over the past decade. We examined status and risk factors for Western- and Chinese fast food consumption and their associations with health outcomes in Chinese children, and examined how maternal factors were associated with child health outcomes. METHODS Data of 1626 students aged 7-16 (11.6 ± 2.0) years and their parents in four mega-cities across China (Beijing, Shanghai, Nanjing, and Xi'an) were collected in the 2015 baseline survey of the Childhood Obesity Study in China Mega-cities. Weight, height, waist circumference, and blood pressure were measured. Food intake was assessed using questionnaire. Mixed models were used to examine the associations. RESULTS Among the children, 11.1% were obese, 19.7% were centrally obese, and 9.0% had hypertension. Obesity prevalence was much higher in boys than in girls (15.2% vs. 6.9% and 27.4% vs. 11.7%, respectively, both P < 0.001). About half (51.9% and 43.6%) of children consumed Western and Chinese fast food, respectively, over the past 3 months. Compared to those with college or above maternal education level, those with elementary school or below maternal education level were 49% more likely to consume Western fast food (odds ratio [OR] and 95% confidence interval [CI]: 1.49 [1.10-2.03]). Chinese fast food consumption rate increased by 12% with each year of increase in child's age (OR and 95% CI: 1.12 [1.02-1.23]). No significant associations between fast food consumption and health outcomes were detected. Adjusting for Western fast food consumption, children with lower maternal education were 71% and 43% more likely to have obesity and central obesity (ORs and 95% CIs: 1.71 [1.12-2.61] and 1.43 [1.00-2.03], respectively), and maternal body mass index was positively associated with child obesity, central obesity, and hypertension (ORs and 95% CIs: 1.11 [1.06-1.17], 1.12 [1.07-1.17], and 1.09 [1.03-1.15], respectively). Results were similar when Chinese fast food consumption was adjusted for. CONCLUSIONS The prevalence of fast food consumption, obesity and hypertension is high among children in major cities in China. Maternal factors affect child outcomes.

Abstract
Scope A high salt (HS) diet is detrimental to cognitive function, in addition to having a role in cardiovascular disorders. However, the method by which an HS diet impairs cognitive functions such as learning and memory remains open. Methods and results In this study, we found that mice on a 7 week HS diet demonstrated disturbed short‐term memory in an object‐place recognition task, and both 4 week and 7 week HS treatments impaired long‐term memory, as evidenced in a fear conditioning test. Mechanistically, the HS diet inhibited memory‐related long‐term potentiation (LTP) in the hippocampus, while also increasing the levels of reactive oxygen species (ROS) in hippocampal cells and downregulating the expression of synapsin I, synaptophysin, and brain‐derived neurotrophic factor in specific encephalic region. Conclusion This suggests that oxidative stress or synaptic protein/neurotrophin deregulation was involved in the HS diet‐induced memory impairment. Thus, the present study provides novel insights into the mechanisms of memory impairment caused by excessive dietary salt, and underlined the importance of controlling to salt absorb quantity.

Abstract
Familial hypercholesterolemia (FH) is the most common genetic disorder in childhood, but in most cases is not detected. High levels of low-density lipoprotein cholesterol are present since the child's birth and this fact will suppose silent development of early atherosclerosis. In cases of homozygous FH, the coronary disease will appear before 20s and in cases of heterozygous FH will occur in middle age. Despite published data, there is not agreement about how and when perform the screening. Familial history of early cardiovascular disease plus presence of hypercholesterolemia in parents is crucial for detection and diagnosis. Actually, it is topic of discussion that it is necessary to achieve therapeutic goals from an early age to improve prognosis. Lifestyle changes are the first line therapy. Statins are the lipid-lowering drugs of choice but the optimal age to start therapy it is still controversial. In this article, current recommendations of expert consensus guidelines about the management and new line therapies of child and adolescents are reviewed.

Abstract
Background/Aims Hypernatremic dehydration in term neonates is associated with inadequate fluid intake, usually related to insufficient lactation. The use of hypotonic fluids is appropriate to dilute serum sodium (SNa), but cerebral edema may develop when it happens abruptly. Our objective was to clarify how to correct hypernatremic dehydration properly. Methods The following databases were searched, limited to studies published until January 31st, 2016: Clinical Trials, MEDLINE/PubMed, EMBASE, LILACS, and the Cochrane Library. We included open-label trials, nonrandomized controlled trials, or prospective and retrospective case series evaluating relevant outcomes. Information regarding the way of administering the treatment, type of fluid used, rates of complications and outcomes, as well as the rate of SNa reduction were collected. Results Searches yielded 771 articles: 64 had the full text reviewed and 9 were included. No randomized clinical trials or systematic reviews focusing on treatment of hypernatremic dehydration and its outcomes were found. We found a scarcity of high quality studies and great methodology heterogeneity. Conclusions More severe hypernatremia is at greater risk of causing severe adverse effects of treatment. There is no consensus about the optimal rate of SNa drop in this population, but a slower correction appears to be safer. Questions as when parenteral fluids are indicated remain unanswered.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2016; 13:ijerph13060572. [PMID: 27338427 PMCID: PMC4924029 DOI: 10.3390/ijerph13060572] [Citation(s) in RCA: 54] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/28/2016] [Revised: 05/31/2016] [Accepted: 05/31/2016] [Indexed: 11/18/2022]
Abstract
This systematic review discusses data on the dietary intake of preschool children living in the Mediterranean countries of the European Union, including the comparison with a Mediterranean-like diet and the association with nutritional status. Specifically, data from the multinational European Identification and Prevention on Dietary and life style induced health effects in children and infants (IDEFICS) study and national studies, such as the Estudo do Padrão Alimentar e de Crescimento Infantil (EPACI) study and Geração XXI cohort in Portugal, ALimentando la SAlud del MAñana (ALSALMA) study in Spain, Étude des Déterminants pré-et postnatals précoces du développement et de la santé de l’ENfant (EDEN) cohort in France, Nutrintake 636 study in Italy, and Growth, Exercise and Nutrition Epidemiological Study in preSchoolers (GENESIS) cohort in Greece, were analyzed. In the majority of countries, young children consumed fruit and vegetables quite frequently, but also consumed sugared beverages and snacks. High energy and high protein intakes mainly from dairy products were found in the majority of countries. The majority of children also consumed excessive sodium intake. Early high prevalence of overweight and obesity was found, and both early consumption of energy-dense foods and overweight seemed to track across toddler and preschool ages. Most children living in the analyzed countries showed low adherence to a Mediterranean-like diet, which in turn was associated with being overweight/obese. Unhealthier diets were associated with lower maternal educational level and parental unemployment. Programs promoting adherence of young children to the traditional Mediterranean diet should be part of a multi-intervention strategy for the prevention and treatment of pediatric overweight and obesity.

Abstract
The manifestation of cardiovascular risk factors, such as hypertension, diabetes, and particularly obesity begins in children and adolescents, with deleterious effects for cardiometabolic health at adulthood. Although the impact of diet on cardiovascular risk factors has been studied extensively in adults, showing that their cardiometabolic health is strongly lifestyle-dependent, less is known about this impact in children and adolescents. In particular, little is known about the relationship between their dietary patterns, especially when derived a posteriori, and cardiovascular risk. An adverse association of cardiovascular health and increased intake of sodium, saturated fat, meat, fast food and soft drinks has been reported in this population. In contrast, vitamin D, fiber, mono-and poly-unsaturated fatty acids, dairy, fruits and vegetables were positively linked to cardiovascular health. The aim of this review was to summarize current epidemiological and experimental evidence on the impact of nutrients, foods, and dietary pattern on cardiometabolic health in children and adolescents. A comprehensive review of the literature available in English and related to diet and cardiometabolic health in this population was undertaken via the electronic databases PubMed, Cochrane Library, and Medline.

High sodium and low potassium intake among Italian children: relationship with age, body mass and blood pressure. PLoS One 2015; 10:e0121183. [PMID: 25853242 PMCID: PMC4390153 DOI: 10.1371/journal.pone.0121183] [Citation(s) in RCA: 55] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2014] [Accepted: 01/28/2015] [Indexed: 12/23/2022] Open
Abstract
Background Hypertension is the leading cause of death in developed countries and reduction of salt intake is recommended as a key preventive measure. Objective To assess the dietary sodium and potassium intakes in a national sample of Italian children and adolescents and to examine their relationships with BMI and blood pressure (BP) in the framework of the MINISAL survey, a program supported by the Italian Ministry of Health. Population and Methods The study population included 1424 healthy subjects (766 boys, 658 girls) aged 6-18 years (mean age: 10.1±2.9) who were consecutively recruited in participating National Health Service centers in 10 Italian regions. Electrolyte intake was estimated from 24 hour urine collections tested for completeness by the concomitant measurement of creatinine content. Anthropometric indices and BP were measured with standardized procedures. Results The average estimated sodium intake was 129 mmol (7.4 g of salt) per day among boys and 117 mmol (6.7 g of salt) among girls. Ninety-three percent of the boys and 89% of the girls had a consumption higher than the recommended age-specific standard dietary target. The estimated average daily potassium intakes were 39 mmol (1.53 g) and 36 mmol (1.40 g), respectively, over 96% of the boys and 98% of the girls having a potassium intake lower than the recommended adequate intake. The mean sodium/potassium ratio was similar among boys and girls (3.5 and 3.4, respectively) and over 3-fold greater than the desirable level. Sodium intake was directly related to age, body mass and BP in the whole population. Conclusions The Italian pediatric population is characterized by excessive sodium and deficient potassium intake. These data suggest that future campaigns should focus on children and adolescents as a major target in the framework of a population strategy of cardiovascular prevention.
