Comparative Study
AIMS
We described long-term trends in obesity using preschool data from New Zealand and compared rates pre- and post-COVID by key demographic variables.
METHODS
Growth data from the B4 School Check (B4SC) information system for the period 1 July 2012 to 30 June 2022 were used to calculate obesity rates. The date 25 March 2020 was the threshold used to compare the rates between pre- and post-COVID periods. Obesity rate ratios for these two periods were calculated for each demographic sub-group.
RESULTS
The overall obesity rate increased by 1.8% after COVID-19. Males had higher obesity rates and a greater absolute increase (2%) in the post-COVID period. The greatest absolute increase in obesity was among Pacific peoples (4.3%), followed by Māori (2.2%). Children in most deprived areas and those in the Auckland Region had greater absolute increases of 3% and 2.5% respectively, post-COVID.
CONCLUSION
The COVID-19 lockdown has had an immediate impact on obesity rates among 4-year-old children, especially for the Pacific population, those living in high deprivation areas and regions with longer periods of lockdown (Auckland). There are implications for public health policy and practice to support children in adopting a healthy lifestyle, especially during pandemics.

Observational Study
Testing a Biobehavioral Model of Chronic Stress and Weight Gain in Young Children (Family Stress Study): Protocol and Baseline Demographics for a Prospective Observational Study.
BACKGROUND
Chronic stress is an important risk factor in the development of obesity. While research suggests chronic stress is linked to excess weight gain in children, the biological or behavioral mechanisms are poorly understood.
OBJECTIVE
The objectives of the Family Stress Study are to examine behavioral and biological pathways through which chronic stress exposure (including stress from COVID-19) may be associated with adiposity in young children, and to determine if factors such as child sex, caregiver-child relationship quality, caregiver education, and caregiver self-regulation moderate the association between chronic stress and child adiposity.
METHODS
The Family Stress Study is a prospective cohort study of families recruited from 2 Canadian sites: the University of Guelph in Guelph, Ontario, and McMaster University in Hamilton, Ontario. Participants will be observed for 2 years and were eligible to participate if they had at least one child (aged 2-6 years) and no plans to move from the area within the next 3 years. Study questionnaires and measures were completed remotely at baseline and will be assessed using the same methods at 1- and 2-year follow-ups. At each time point, caregivers measure and report their child's height, weight, and waist circumference, collect a hair sample for cortisol analysis, and fit their child with an activity monitor to assess the child's physical activity and sleep. Caregivers also complete a web-based health and behaviors survey with questions about family demographics, family stress, their own weight-related behaviors, and their child's mental health, as well as a 1-day dietary assessment for their child.
RESULTS
Enrollment for this study was completed in December 2021. The final second-year follow-up was completed in April 2024. This study's sample includes 359 families (359 children, 359 female caregivers, and 179 male caregivers). The children's mean (SD) age is 3.9 years (1.2 years) and 51% (n=182) are female. Approximately 74% (n=263) of children and 80% (n=431) of caregivers identify as White. Approximately 34% (n=184) of caregivers have a college diploma or less and nearly 93% (n=499) are married or cohabiting with a partner. Nearly half (n=172, 47%) of the families have an annual household income ≥CAD $100,000 (an average exchange rate of 1 CAD=0.737626 USD applies). Data cleaning and analysis are ongoing as of manuscript publication.
CONCLUSIONS
Despite public health restrictions from COVID-19, the Family Stress Study was successful in recruiting and using remote data collection to successfully engage families in this study. The results from this study will help identify the direction and relative contributions of the biological and behavioral pathways linking chronic stress and adiposity. These findings will aid in the development of effective interventions designed to modify these pathways and reduce obesity risk in children.

OBJECTIVE
Childhood flatfoot and overweight can affect children's quality of life and influence their development, increasing the risk of musculoskeletal problems in adulthood. There is evidence linking overweight to the development of childhood flatfoot. The aim of the study was to assess the relationship between the weight status of school children and their foot posture and to determine whether there are differences between both sexes.
METHODS
A cross-sectional study (2021) in a sample of schoolchildren (n=296, 153 boys and 143 girls, mean age 8.5±2.7) from Colegio San Agustín in Zaragoza was carried out. Foot posture was assessed according to the foot postural index, and weight status was obtained using the body mass index according to the criteria of the International Obesity Task Force. The correlation between weight status and foot posture was analyzed using Spearman's coefficient. The Chi-square test was used to determine the differences between the variables according to sex.
RESULTS
Weight status showed no correlation with foot posture in boys (right foot p=0.095; left foot p=0.067) and girls (right foot p=-0.04; left foot p=0.008). Boys had a higher prevalence of flat feet than girls (boys foot posture index=8; girls foot posture index=7; right foot p<0.036; left foot p<0.009). Boys had higher prevalence of overweight than girls (28.75; 18.18, p<0.027).
CONCLUSIONS
Weight status has no effect on foot posture. The male gender could predispose to the development of flat feet and overweight in childhood.

This article aims to analyse the relationship between physical activity (PA) environment at schools, sex, age, and obesity in children, using a network approach. This is a cross-sectional study, with 1,200 children (8.1±1.0 years old) from eight public schools in the same municipality. Weight and height measurements were assessed to calculate the Body Mass Index (BMI) and classified as healthier weight or overweight. To assess the PA environment at school, a interview with the school´s manager was conducted. The association between the PA environment at school and obesity was tested using a Network Analysis performed on the Jasp software. Positive associations between BMI and Physical Education classes (0.847), physical education teacher (0.349), break duration (0.564), and indoor sports court (0.662) were observed. Negative associations were seen with sex (-0.212) age (-0.387), extracurricular PA (-0.492), and playground (-0.557). Additionally, the centrality indicators highlighted extracurricular PA (1.789) as the variables with the highest betweenness values, and BMI with the highest closeness (2.239) and strength (1.230) values. Extracurricular PA and the presence of playgrounds in school´s environment are associated with healthier weight in low-income children.

Nutricion Hospitalaria May 2024a relationship has been observed between elevated levels of liver enzymes and uric acid with the presence of metabolic syndrome (MS) in the pediatric population.
INTRODUCTION
a relationship has been observed between elevated levels of liver enzymes and uric acid with the presence of metabolic syndrome (MS) in the pediatric population.
OBJECTIVE
to compare serum liver enzyme and uric acid levels between adolescents with and without MS.
METHODS
a cross-sectional study was carried out in adolescents with obesity between 10 and 18 years old. Somatometric data, serum insulin, lipid profile, uric acid levels and liver enzymes (aspartate aminotransferase [AST], alanine aminotransferase [ALT] and gamma-glutamyl transferase [GGT]) were analyzed.
STATISTICAL ANALYSIS
Student's t test or the Chi-square test was used to evaluate differences between groups.
RESULTS
a total of 1095 adolescents with obesity were included (444 with MS and 651 without MS). The group with MS had a higher BMI (with MS 2.28 vs without MS 2.11 p < 0.001), with no difference in body fat (42.9 % vs 42.9 %, p = 0.978). The MS group had significantly higher levels of AST (34.4 vs. 29.5, p = 0.013), ALT (42.2 vs. 34.6, p = 0.003), and uric acid (6.17 vs. 5.74, p = 0.002). comparison to the group without MS. The proportion of ALT (40.5 % vs 29.5 %, p = 0.029) and altered uric acid (58.1 % vs. 45.6 %, p = 0.019) was higher in the MS group.
CONCLUSIONS
serum levels of ALT, AST and uric acid in adolescents with obesity and MS were higher compared to those without MS. Altered ALT was a risk factor for SM.

Dental and Medical Problems Jun 2024Dentofacial infection resulting from untreated dental caries or periodontal disease is a serious disease that can spread to deeper tissues of the face and neck.
BACKGROUND
Dentofacial infection resulting from untreated dental caries or periodontal disease is a serious disease that can spread to deeper tissues of the face and neck.
OBJECTIVES
The present study aimed to analyze the salivary cytokine profile and oxidative stress parameters as potential biomarkers of acute odontogenic infections in children.
MATERIAL AND METHODS
The prospective study group (DI) consisted of 28 children aged 3-17 years with acute dentofacial infections, and the control group (CG) comprised 52 children aged 4-17 years with uncomplicated dental caries. The cytokine profile was analyzed using the Bio-Plex Pro™ Human Cytokine 27-plex kit. In addition, oxidative stress parameters, such as catalase (CAT), glutathione reductase (GR), superoxide dismutase (SOD), manganese SOD (Mn-SOD), copper-zinc SOD (CuZn-SOD), total antioxidant capacity (TAC), total oxidant status (TOS), and malondialdehyde (MDA), in the saliva of children in both groups were compared.
RESULTS
The levels of interleukin 6 (IL-6), macrophage inflammatory protein 1 alpha (MIP-1α) and tumor necrosis factor alpha (TNF-α) were significantly increased in children with dentofacial infections as compared to CG. In contrast, the levels of other pro-inflammatory cytokines, such as IL-1β, IL-1 receptor agonist (IL-Ra), IL-8, monocyte chemoattractant protein 1 (MCP-1), and MIP-1β, did not show statistically significant differences between the 2 groups. Among the measured oxidative stress and antioxidative parameters, only CAT and GR were elevated in children with dentofacial infections as compared to controls.
CONCLUSIONS
IL-6, MIP-1α, TNF-α, CAT, and GR can serve as selective biomarkers of oral cavity inflammation in children. These biomarkers can be useful in identifying and monitoring the progress and treatment of bacterial infections resulting in dentofacial inflammation.

Journal of the Endocrine Society May 2024Steatotic liver disease is common but overlooked in childhood obesity; diagnostic methods are invasive or expensive.
CONTEXT
Steatotic liver disease is common but overlooked in childhood obesity; diagnostic methods are invasive or expensive.
OBJECTIVE
We sought to determine the diagnostic accuracy of vibration-controlled transient elastography (VCTE) compared with magnetic resonance imaging (MRI) in adolescents with obesity and high risk for hepatosteatosis.
METHODS
Baseline data in 3 clinical trials enrolling adolescents with obesity were included (NCT03919929, NCT03717935, NCT04342390). Liver fat was assessed using MRI fat fraction and VCTE-based controlled attenuation parameter (CAP). Hepatosteatosis was defined as MRI fat fraction ≥5.0%. The area under the receiver-operating characteristic curves (AUROCs) for CAP against MRI was calculated, and optimal CAP using the Youden index for hepatosteatosis diagnosis was determined.
RESULTS
Data from 82 adolescents (age 15.6 ± 1.4 years, body mass index 36.5 ± 5.9 kg/m, 81% female) were included. Fifty youth had hepatosteatosis by MRI (fat fraction 9.3% ; 95% CI 6.7, 14.0), and 32 participants did not have hepatosteatosis (fat fraction 3.1%; 95% CI 2.2, 3.9; < .001). The hepatosteatosis group had higher mean CAP compared with no hepatosteatosis (293 dB/m; 95% CI 267, 325 vs 267 dB/m; 95% CI 248, 282; = .0120). A CAP of 281 dB/m had the highest sensitivity (60%) and specificity (74%) with AUROC of 0.649 (95% CI 0.51-0.79; = .04) in the entire cohort. In a subset of participants with polycystic ovary syndrome (PCOS), a CAP of 306 dB/m had the highest sensitivity (78%) and specificity (52%) and AUROC of 0.678 (95% CI 0.45-0.90; = .108).
CONCLUSION
CAP of 281 dB/m has modest diagnostic performance for hepatosteatosis compared with MRI in youth with significant obesity. A higher CAP in youth with PCOS suggests that comorbidities might affect optimal CAP in hepatosteatosis diagnosis.

Review
: The number of corneal transplants is rising, with the aim to treat a spectrum of diseases ranging from dystrophies to corneal opacities caused by trauma or chemical burns. Refractive outcomes after this procedure are often impossible to predict and associated with high levels of astigmatism. However, there are many techniques that affect the reduction of astigmatism and improve the quality of life of patients. : The aim was to compare the improvement in postoperative visual acuity (logMAR) and amount of corneal astigmatism (Diopters) after corneal keratoplasty in patients who additionally underwent a surgical procedure, which affects the reduction in postoperative astigmatism, and to determine the most effective method. A thorough search was carried out across online electronic databases including PubMed, Embrase, Ovid MEDLINE, Scopus, and Web of Science, using combinations containing the following phrases: postoperative astigmatism, post-keratoplasty astigmatism, anterior lamellar keratoplasty (ALK), deep anterior lamellar keratoplasty (DALK), posterior lamellar keratoplasty, endothelial keratoplasty (EK), penetrating keratoplasty (PK), corneal transplant, keratoplasty, refractive surgery, kerato-refractive surgery, laser in situ keratomileusis (LASIK), and femtosecond LASIK. This was to determine all English-language publications that discuss refractive operations for postoperative or post-keratoplasty astigmatism. These bibliographies were searched for English-language publications published between 2010 and 2023. We proceeded to review each detected record's reference list. Study characteristics such as study design, sample size, participant information, operations performed, and clinical outcomes were all extracted. The Comprehensive Meta-Analysis software (version 3.3.070, 2014) was used to perform the analysis. The threshold of 0.05 for -values was considered statistically significant. All effect sizes are reported as standardized differences (Std diff) in means with a 95% confidence interval (CI) and visualized graphically as forest plots. Publication bias is presented as a funnel plot of standard error by Std diff in means. Four methods were used to evaluate the heterogeneity among the studies: Q-value, I, chi-square (χ), and tau-squared. We included 21 studies that randomized 1539 eyes that underwent corneal transplantation surgery either by PKP, DALK, or DSEAK techniques. The results showed the most significant improvement in the visual acuity and significant decrease in the corneal astigmatism after laser surgery procedures, like femtosecond-assisted keratotomy after DALK and PKP and LASIK after DSEAK.

Review
The prevalence of childhood obesity and its associated comorbidities is a growing global health problem that disproportionately affects populations in low- and middle-income countries (LMICs) and minority ethnicities in high-income countries (HICs). The increased childhood obesity disparities among populations reflect two concerns: one is HICs' ineffective intervention approaches in terms of lifestyle, nutrition and physical activity in minority populations, and the second is the virtually non-existent lifestyle obesity interventions in LMICs. This article provides guidelines on childhood obesity and its comorbidities in high-risk minority populations based on understanding the prevalence and effectiveness of preventative lifestyle interventions. First, we highlight how inadequate obesity screening by body mass index (BMI) can be resolved by using objective adiposity fat percentage measurements alongside anthropometric and physiological components, including lean tissue and bone density. National healthcare childhood obesity prevention initiatives should embed obesity cut-off points for minority ethnicities, especially Asian and South Asian ethnicities within UK and USA populations, whose obesity-related metabolic risks are often underestimated. Secondly, lifestyle interventions are underutilised in children and adolescents with obesity and its comorbidities, especially in minority ethnicity population groups. The overwhelming evidence on lifestyle interventions involving children with obesity comorbidities from ethnic minority populations shows that personalised physical activity and nutrition interventions are successful in reversing obesity and its secondary cardiometabolic disease risks, including those related to cardiorespiratory capacity, blood pressure and glucose/insulin levels. Interventions combining cultural contextualisation and better engagement with families are the most effective in high-risk paediatric minority populations but are non-uniform amongst different minority communities. A sustained preventative health impact can be achieved through the involvement of the community, with stakeholders comprising healthcare professionals, nutritionists, exercise science specialists and policy makers. Our guidelines for obesity assessment and primary and secondary prevention of childhood obesity and associated comorbidities in minority populations are fundamental to reducing global and local health disparities and improving quality of life.
