Body Weight In Children Research Articles

Economic disadvantage during childhood, obesity, and diabetes across three birth cohorts of older Mexicans.

Diabetes prevalence has increased markedly in Mexico. We examined the individual and joint contributions of economic disadvantage during childhood (EDDC) and elevated body weight on diabetes prevalence in three cohorts of Mexican adults. Data on those 60-69 years old from the 1930-39, 1940-49, and 1950-59 birth cohorts in Waves 1 (2001), 3 (2012), and 5 (2018) of the Mexican Health and Aging Study were used. EDDC was defined as the absence of a toilet in the household before age 10. Body mass status was defined using self-reported perceived body image at age 50. Diabetes was based on respondent reports. Supplementary analyses using HbA1c as a criterion for diabetes were conducted. A regression-decomposition approach was implemented. Logistic regression models included adjustments for sociodemographic characteristics and access to medical care. Diabetes prevalence was 23% overall and 11%, 25%, and 26% in the 1930-39, 1940-49, and 1950-59 cohorts, respectively. EDDC declined across successive cohorts, while the prevalence of overweight/obesity at age 50 increased. EDDC and overweight/obesity were associated with higher odds of reporting diabetes. A scenario that eliminates disadvantaged EDDC reduced diabetes prevalence by 11% in a pooled sample, while eliminating overweight/obesity reduced it by 30%. Overweight/obesity explained 42% of the rise in diabetes prevalence between the 1930-39 and 1950-59 cohorts. Improvement in EDDC explained 18% of the rise in diabetes prevalence between 1930-39 and 1950-59 cohorts. High body weight across Mexican birth cohorts seemed to offset the potential benefits from improvements in childhood conditions on adult diabetes risk.

Predictors of high blood pressure in children from 6 to 11 years: The PREDI cohort study

Abstract Background Hypertension is an important cardiovascular disease (CVD) in Brazil that affects approximately 30% of the adult population and accounts for nearly 50% of CVD-related deaths in the country. Identifying the main predictors of high blood pressure (BP) during childhood will help prevent the development of other CVDs in adulthood and deaths. This study aimed to estimate the effect of biological, demographic, and socioeconomic characteristics on the child’s BP at 6, 9 and 11 years of age. Methods Cohort study conducted with 181 children in Joinville city, southeastern Brazil. Individual data were collected during three follow-ups (2016, 2021, and 2023) in a private room of the family’s home. BP was measured by the auscultatory method. Poisson regression analysis adjusted for important covariates was used to estimate the relative risk (RR) of maternal and child weight status, demographic, and socioeconomic characteristics on the child’s BP at ages 6, 9 and 11. Results The prevalence of high BP in children at ages 6, 9 and 11 was 26.5%, 20.4% and 3.0%, respectively. Pre-pregnancy body mass index (BMI) and the child’s BMI were associated with high BP over the period investigated. The risk of children having high diastolic BP from 6 to 11 years of age was 6% higher (RR = 1.06; 95%CI 1.01, 1.11) when mothers had pre-pregnancy BMI ≥25 kg/m2, even after adjusting for child BMI. For each one kg/m2 increase in child BMI, the risk of children having high systolic BP pressure increased by 14% (RR = 1.14; 95%CI 1.05, 1.23), even after adjusting for pre-pregnancy BMI. Conclusions Pre-pregnancy excess body weight and increased child BMI were associated with high BP in children from 6 to 11 years of age. Addressing pre-pregnancy excess body weight and overweight in childhood, combined with BP monitoring from the age of six, are actions that can prevent the development of CVDs in adulthood, thus reducing a serious global public health problem. Key messages • Encouraging parents to monitor their children’s BP is essential to prevent associated chronic diseases throughout life. • Identifying children with altered blood pressure is an important public health indicator.

Healthy Change Intervention: A Cluster RCT in Preschooler Mothers in Mexico and the United States.

To assess effects of Healthy Change intervention on maternal perception of her child's body weight (MPCW), maternal feeding style, and obesogenic home environment. A randomized control trial was conducted, consisting of two arms: the intervention group received the Healthy Change program, and the control group received the Hygiene and Accident Prevention program. A total of 356 mother-preschool child dyads participated, 182 in the intervention group and 174 in the control group, residing in Mexico and the United States. Data were collected at baseline and after the program through self-administered questionnaires completed by mothers and child anthropometric measurements. Although no significant between-group difference in pre- and post-intervention change of MPCW was found, sub-analyses revealed that a higher proportion of mothers in the intervention group accurately perceived their child's body weight at the study endpoint using categorical (67% vs. 57.1%, p < 0.005) and visual scales (48.9% vs. 41.8%, p < 0.015). Additionally, more mothers of overweight children in the intervention group accurately perceived their children's overweight and obese status compared to those in the control group (29.8% vs. 10.3%, X2 = 4.26, df = 1, p < 0.039). The intervention group also displayed a higher proportion of mothers with authoritative feeding style (26.4% vs. 16.5%, p < 0.036) and significantly higher family nutrition and physical activity scores (29.1 vs. 28.0, p < 0.000) at the study endpoint. Healthy Change Intervention led to improved accuracy of MPCW, a shift toward maternal authoritative feeding styles, and positive changes in obesogenic home environments.

The Role of Mothers’ Varied Parenting Styles in Childhood Obesity

Objective: The aim of this study is to evaluate the role of mothers' democratic, authoritarian, permissive, and overprotective parenting styles in childhood obesity and mothers' perception of their children's body weight. Method: The research was cross-sectional in design, and a total of 94 children aged between two and six years were included, together with their mothers. Mothers were administered the Parental Attitude Scale, and children's Body Mass Index (BMI) was classified using age- gender-specific tables of the International Obesity Task Force (IOTF). The effect of mothers' parental attitudes on their children's BMI groups was evaluated. However, mothers matched their child's appearance to the appearance they thought corresponded to the age and gender-specific weight plot and mothers' weight perceptions were evaluated. Results: The prevalence of overweight-obesity among children was found to be 19.2%. There wasn’t statistically difference between democratic, authoritarian, overprotective and permissive parenting styles and BMI categories of children (p=0.819, p=0.878, p=0.319, p=0.494). The mothers of overweight-obese children perceived their children as significantly overweight compared to other children (p

Adaptation and Validation of the MapMe Body Image Scales in Spanish Parents of Schoolchildren.

Childhood overweight and obesity is a worldwide problem and to treat it parents' detection has to be improved. The MapMe Body Image Scales (BIS) are a visual tool developed to improve parental perception of child weight in the United Kingdon (UK) based on British growth reference criteria. The aim of this study was to make a transcultural adaptation and validation of the MapMe BIS in Spain based on International Obesity Task Force (IOTF) cut offs A descriptive cross-sectional study was done. First, a translation and cultural adaptation was carried out. A total of 155 10-11-year-old children and their parents participated in this study. Children were measured to calculate their weight status, Body Mass Index (BMI), Body Fat Percentage (BFP) and Waist Circumference (WC), and their parents completed a purpose designed questionnaire about their perception and satisfaction of child's body weight status using the adapted BIS. Test-retest reliability, criterion validity and concurrent validity of the adapted BIS were analyzed. This study shows that the adapted MapMe BIS has good psychometric properties and is a suitable visual scale to assess parental perception of weight status in 10 and 11-year-old children in Spain.

Abstract P409: Maternal Macronutrient Intake at Pregnancy and Offspring Growth Trajectory Before Adulthood: A Prospective Analysis in the Growing Up Today Study 2 Cohort

Background: Childhood obesity has become a public health challenge globally, with increasing prevalence worldwide. Existing studies have indicated a potential link between maternal macronutrients intake and subsequent weight changes in their offspring during childhood. However, the long-term relationship between maternal macronutrient consumption at pregnancy and the growth trajectory of offspring into adulthood remains unclear. Objectives: We aim to investigate the relationship between maternal macronutrients intake at pregnancy and the trajectory of the offspring BMI z-score, as well as the risk of becoming overweight or obese before adulthood. Method: We included 5,700 children from the Growing Up Today Study 2 born to 4,697 mothers who participated in the Nurses’ Health Study II . Diet was assessed using a validated food frequency questionnaire in 1991 approximately during or before the pregnancy at issue. Age- and gender-specific BMI thresholds described by the International Obesity Task Force were used to define overweight and obesity in childhood and adolescence. Multivariable linear and log-binomial regression models with generalized estimating equations were used to evaluate the association between maternal macronutrients intake at pregnancy and offspring BMI z-score trajectory and the risk of overweight or obesity. Results: During follow-up, 2145 (37.6%) GUTS2 participants met the criteria of overweight or obesity.After multivariate adjustment for maternal, offspring risk factors, total maternal total energy and carbohydrate percent energy, comparing to the 1 st quartile, the highest quartile of total protein consumption at pregnancy was associated with 0.14-unit [β: 0.14 (95% CI: 0.02, 0.26; P-trend = 0.03)] increase in BMI z-score, while no significant association was observed for the risk of offspring overweight or obesity [RR: 1.17 (95% CI: 0.94, 1.46; P-trend = 0.12)]. The relationship persisted for the top quartile of animal protein energy intake [β: 0.14 (95% CI: 0.01, 0.27; P-trend = 0.03)], but not for vegetable protein consumption. Intakes of dietary fats and carbohydrates were not associated with BMI z-score or risk of overweight or obesity. Furthermore, individual macronutrient subgroups, such as saturated fats, mono- and poly-unsaturated fats, or whole grains and refined grains, were not associated with the outcomes of interest, either. Conclusion: Maternal animal protein intake at pregnancy is positively associated with higher offspring BMI z-score before adulthood, but not the risk of developing overweight or obesity during childhood. Other macronutrients are not significantly associated with these childhood body weight outcomes. Overall, these data suggest that the macronutrient composition of maternal diet at peri-pregnancy period has minimal impact on offspring body weight in this well-nourished population.

Analyzing Children's Weight Growth Variations and Associated Factors in Ethiopia, India, Peru, and Vietnam: Using Fractional Polynomial Mixed-Effects Model.

Children's growth is increasingly considered a key mediator of later life outcomes. When examining weight growth, the correlation between repeated observations on the same subject must be regarded as well-modelled. This study aimed to analyze children's weight growth variations and associated factors in Ethiopia, India, Peru, and Vietnam using a fractional polynomial mixed-effects model. This study used longitudinal data from the Young Lives Cohort Study conducted from 2002 to 2016 in Ethiopia, India, Peru, and Vietnam. The study included 7,140 children of 1 to 15 years old A fractional polynomial mixed-effects model was used to analyze the data. Ethiopian, Peruvian, and Vietnamese children had significantly higher average body weights than children in India (1.426, P<0.001; 1.992, P<0.001; 1.334, P<0.001, respectively). Girl children's average body weight was significantly 0.15 times less than that of boys (-0.148; P=0.027). The average weight of rural children was significantly 0.671 times less than that of urban children (0.671, P<0.001). Children from Peru and Vietnam had higher rates of weight change than those from India. However, the rate of weight change was lower in Ethiopian children than in Indian children. Children from urban areas had a significantly higher rate of weight gain than those from rural areas. Country, sex, residence, parental education, household size, wealth, good drinking water, and reliable power affected children's longitudinal weight growth. Therefore, WHO and the nation's health ministry should monitor children's weight growth status and these associated factors to plan future action.

Growth patterns of children under 5 years old in rural area northern of Abha, Aseer Region, Saudi Arabia.

Measuring and monitoring physical growth is a key element in assessing children's health. The physical and mental development of a growing child are indicators of good health and nutrition. This study aimed to explore the patterns of growth parameters among children under 5 years old attending primary health care centres (PHCCs) in rural northern Abha. Feeding habits during the first 2 years of life were also assessed. This study was conducted on 1-5 April 2022 in all (PHCCs) in Billasamr and Ballahmar, two neighbourhoods of northern Abha. The investigator designed a form for collecting each child's age (months), weight (kilograms), gender, birth order, number of family members, type of feeding (exclusive breastfeeding, exclusive bottle feeding, or mixed feeding), and duration of exclusive breastfeeding. Gender affected the body weight of Saudi infants, as boys weighed significantly more than age-matched girls. Birth order also affected body weight. During the first and third years of life, Saudi children's body weight was not significantly affected by feeding type. During the second and fifth years of life, formula-fed children weighed more than breastfed or combination-fed children. However, during the fourth year of life, body weight was highest in combination-fed children. Growth patterns over time, established from multiple data points, must be used in conjunction with other medical and family history to evaluate appropriate growth. Recording and tracking body size, especially recumbent length and weight, as part of well-baby care is critical for any assessment of child wellbeing and health status.

Body weight in childhood, adolescence, and young adulthood in relation to later risk of disabilities and early retirement among Danish female nurses.

Obesity is now the most common health problem in the younger population in Western societies and obesity rates are higher in lower socioeconomic status (SES) groups. We investigated whether overweight in childhood, independently of overweight in adulthood, influenced adult employment status and later risk of having disabilities. Using data from the Danish Female Nurse Cohort study, we examined associations between overweight in childhood/adolescence, and young adulthood and disabilities and early retirement in later adulthood (>44 years) and whether it was influenced by menopausal age (<or ≥52 years). We analysed data from 10,363 female nurses recruited in 1999, who reported whether they, as children, were larger or of similar weight size as their peers at any age below 13 years, between 13 and 19 years, their weights, and heights at 25 years, their current work situation and whether they had had disabilities for more than 6 months. Our results showed that overweight in childhood, adolescence and young adulthood was associated with an increased risk of disabilities and early retirement. Especially childhood overweight that did not persist into adulthood was associated with an increased risk of disabilities (OR = 1.82, 95% CI = 1.26-2.63) and early retirement (OR = 2.05, 95% CI = 1.38-3.03) in the postmenopausal group. A similar increased risk for disabilities (OR = 1.76, 95% CI = 1.26-2.47) was seen for adolescent overweight that did not persist into adulthood. The results show that in a well-educated population of women, overweight in childhood and/or adolescence had adverse socioeconomic consequences for later risk of disabilities and early retirement irrespective of weight status in adulthood.

Effects of poor eating habits on children's body weight

The primary objective of this research is to delve into the correlation between suboptimal dietary habits and the body weight of children residing in Mostar city, Bosnia and Herzegovina. By examining the dietary patterns prevalent among the youth in this specific urban setting, the study seeks to uncover how these habits may be linked to variations in body weight. Through a comprehensive investigation, the aim is to contribute valuable insights into the intricate relationship between eating behaviors and the physical well-being of children in Mostar, thereby informing potential interventions or strategies for promoting healthier lifestyles within this population. In conclusion this pattern of dietary habits not only influences physical health but also has implications for overall well-being and may pose challenges for the long-term health trajectory of school-age boys. It underscores the importance of promoting healthier dietary choices and lifestyle habits from an early age to mitigate the potential adverse effects on children's health.

Basic taste sensitivity, eating behaviour, food propensity and BMI of preadolescent children: How are they related?

Taste sensitivity has been reported to influence children's eating behaviour and contribute to their food preferences and intake. This study aimed to investigate the associations between taste sensitivity, eating behaviour, food frequency and BMI (Body Mass Index) in preadolescents. Preadolescents' taste sensitivity was measured by detection threshold of sweetness (sucrose), sourness (citric acid), saltiness (sodium chloride), bitterness (caffeine, quinine), and umami (monosodium glutamate). In addition, the Child Eating Behaviour Questionnaire (CEBQ), the Food Propensity Questionnaire (FPQ) measuring food frequency, and the children's body weight and height were completed by the parents. A total of 69 child-parent dyads participated (preadolescents mean age =10.9 years). Taste sensitivity to caffeine bitterness was significantly associated with eating behaviour in food responsiveness, emotional overeating, and desire to drink. The preadolescents who were less sensitive to caffeine bitterness had higher food responsiveness scores. Those who were less sensitive to caffeine bitterness and to sweetness had higher emotional overeating scores. In addition, preadolescents who were less sensitive to sourness and bitterness of both caffeine and quinine demonstrated to have higher scores in desire to drink. There was no association between taste sensitivity and FPQ, but significant differences were observed across preadolescents' BMI for FPQ of dairy food items, indicating higher consumption of low-fat milk in the overweight/obese compared to the underweight/normal-weight subjects. There was no significant difference in taste sensitivity according to BMI. Preadolescents' eating behaviour differed across BMI, demonstrating a positive association between BMI and food approach, and a negative association between BMI and food avoidance. This study contributes to the preliminary understanding of the relationships between taste sensitivity and eating behaviour in preadolescents. The results may be used to develop effective strategies to promote healthy eating practices by considering taste sensitivity in preadolescents.

Consumption of 100% Fruit Juice and Body Weight in Children and Adults

Concerns have been raised that frequent consumption of 100% fruit juice may promote weight gain. Current evidence on fruit juice and weight gain has yielded mixed findings from both observational studies and clinical trials. To synthesize the available evidence on 100% fruit juice consumption and body weight in children and adults. MEDLINE, Embase, and Cochrane databases were searched through May 18, 2023. Prospective cohort studies of at least 6 months and randomized clinical trials (RCTs) of at least 2 weeks assessing the association of 100% fruit juice with body weight change in children and adults were included. In the trials, fruit juices were compared with noncaloric controls. Data were pooled using random-effects models and presented as β coefficients with 95% CIs for cohort studies and mean differences (MDs) with 95% CIs for RCTs. Change in body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) was assessed in children and change in body weight in adults. A total of 42 eligible studies were included in this analysis, including 17 among children (17 cohorts; 0 RCTs; 45 851 children; median [IQR] age, 8 [1-15] years) and 25 among adults (6 cohorts; 19 RCTs; 268 095 adults; median [IQR] age among cohort studies, 48 [41-61] years; median [IQR] age among RCTs, 42 [25-59]). Among cohort studies in children, each additional serving per day of 100% fruit juice was associated with a 0.03 (95% CI, 0.01-0.05) higher BMI change. Among cohort studies in adults, studies that did not adjust for energy showed greater body weight gain (0.21 kg; 95% CI, 0.15-0.27 kg) than studies that did adjust for energy intake (-0.08 kg; 95% CI, -0.11 to -0.05 kg; P for meta-regression <.001). RCTs in adults found no significant association of assignment to 100% fruit juice with body weight but the CI was wide (MD, -0.53 kg; 95% CI, -1.55 to 0.48 kg). Based on the available evidence from prospective cohort studies, in this systematic review and meta-analysis, 1 serving per day of 100% fruit juice was associated with BMI gain among children. Findings in adults found a significant association among studies unadjusted for total energy, suggesting potential mediation by calories. Further trials of 100% fruit juice and body weight are desirable. Our findings support guidance to limit consumption of fruit juice to prevent intake of excess calories and weight gain.

Evaluation of the Relationships Among Mindful Eating, Environmental Beliefs, Adherence to the Mediterranean Diet, and Obesity in Children.

This study aimed to evaluate the relationship between adherence to the Mediterranean diet (MD), mindful eating, environmental beliefs, and obesity in children. The study included 318 children (50.6% male, 49.4% female, 10.0 ± 0.73 years old). Data were obtained using survey and a face-to-face interview method. The questionnaire includes general information, anthropometric measurements, the New Ecological Paradigm Scale for Children (NEP), the Mediterranean Diet Quality Index for children and adolescents (KIDMED), and the Mindful Eating Questionnaire for Children. According to the KIDMED classification, 52.5% of the children were in the group that needs improvement, 35.2% were in the low diet quality group, and 12.3% were in the optimal MD group. The Mindless score was higher in overweight/obese children compared to the normal body mass index (BMI) group (P < .05). Awareness, NEP, and KIDMED scores were the lowest in overweight/obese children (P < .05). In regression analysis, the father's age, KIDMED, and Awareness scores related to NEP scores positively (R2 : 0.545, P < .001). Also, children's body mass index-related KIDMED scores negatively, and awareness and NEP scores related KIDMED scores positively (R2 : 0.276, P < .001). Our results show that higher adherence to the MD is associated with higher environmental beliefs. Children with higher mindful eating have higher environmental beliefs and adherence to the MD, and these scores are lower in obese children. Therefore, raising generations that adopt sustainable diet models and have high environmental awareness is necessary. This research provides significant findings for future clinical studies on children's body weight maintenance and sustainability. Cite this article as: Bozkurt O, Kocaadam-Bozkurt B, Koçyiğit E.

Children and chrono-exercise: Timing of physical activity on school and weekend days depends on sex and obesity status

ABSTRACT Recommendations for physical activity (PA) typically focus on frequency, intensity, duration, and type, but timing (chrono-exercise) is also important. The objective of this study is to describe when children are active on school and weekend days and explore PA timing across sex and body mass index (BMI) categories. 359 children (53% male), aged 9.6 (0.9) y, were categorized as normal weight (≥-1 standard deviations (SD) and <1SD; n = 193), overweight (≥1SD and <2SD; n = 80), or obese (≥2SD; n = 86) using WHO BMIz. Moderate-to-vigorous PA (MVPA) was assessed using ActiGraph LS-7164. The results are described as Mean(SD). ANOVA evaluated MVPA across sexes and BMI categories. Normal weight boys were more active than boys with obesity on school (Δ20.33 min; p < 0.001) and weekend days (Δ15.04 min; p < 0.05). On school days, significant differences existed between 9:00 h-11:00 h and 12:00 h-14:00 h (p < 0.017), while on weekends, smaller differences existed throughout the day. Girls’ MVPA was similar across BMI categories, on all days (p > 0.05). On school days, 12:00 h-13:00 h represented the most active hour for all participants (~14% total daily MVPA). Peak weekend MVPA was distributed across multiple hours. Differences in MVPA timing emerged on school-days and weekends. Timing may be important when examining the nuances of MVPA in relation to sex and bodyweight in children.

Ultra-Processed Food as Mediator of the Association between Birthweight and Childhood Body Weight Outcomes: A Retrospective Cohort Study.

Previous studies have shown conflicting findings regarding the association between birthweight and childhood adiposity. We aimed to explore the interaction between ultra-processed food (UPF) and birthweight and its associations with bodyweight markers. The retrospective analysis of data from a Multicity Cohort Study across eastern China was conducted. UPF was computed as percentage of the energy intake and categorized into quartiles. Birthweight was categorized into low (LBW), normal (NBW) and high (HBW). The BMI z-score was calculated using the lambda-mu-sigma method. The sex- and age-specific BMI cutoff points were used to define weight status. Generalized linear models were used to examine modification effects and were performed after adjustment for covariates. The mean percentage of energy intake from UPF was 27.7% among 1370 children. Of all children, 2.3% and 21.4% were born with LBW and HBW, respectively. HBW was a permanent risk for high BMI measures, while LBW was associated with increased BMI measurements only by the addition of the interaction term. The subgroup analysis revealed that HBW and LBW were positively associated with BMI measurements in the lowest UPF intake (Q1), while HBW was related to high BMI measures in Q4. Our findings support efforts to recommend limiting UPF intake, especially for LBW children.

Association of Early Childhood Caries with Body Mass Index, Dietary Habits, and Socioeconomic Status among Preschool Children of Kelambakkam.

One of the most prevalent oral diseases affecting preschoolers, early childhood caries (ECC), can significantly lower a child's quality of life. The pain and discomfort that ECC causes will alter the child's eating habits, which will have an impact on both their physical and mental health, as shown by the deviation from the body mass index (BMI). Dental caries and deviation from the normal BMI are both significantly influenced by children's eating habits and socioeconomic status (SES). To determine the association of ECC with BMI, dietary habits, and SES among 3-6-year-old preschool children. A cross-sectional study was conducted among 375 preschool children of 3-6 years of age. The decayed, missing, or filled teeth (deft) index was used to determine the caries status. Measurement of height (m) and weight (kg) was done using a stadiometer and electronic weighing machine. For each child, the BMI (kg/m2) was calculated, and the child's body weight status was assessed using Centers for Disease Control and Prevention (CDC)-based classification. Questionnaires were collected with demographic details, 3 days diet diary, and the SES of parents. The dietary habit and SES were obtained from the healthy eating index-2005 (HEI-2005) score and Modified Kuppuswamy's Scale 2018. All the data were entered and analyzed using Statistical Package for the Social Sciences (SPSS) software V 20.0. The prevalence of ECC was 44.8%. On comparison of mean height, weight, and BMI scores, there was a significant difference in mean weight (p = 0.006) and BMI (p = 0.001) among the two study groups. Children with ECC had a lower HEI-2005 score and belonged to a lower social class compared to caries-free children (p = 0.001). Children with ECC are significantly associated with BMI being overweight, or risk of being overweight; lower grades of SES and lower total score of HEI-2005 with poor diet and diet that needs improvement.

Cord Blood Spexin Level in Mothers with Obesity-Forecast of Future Obesity?

Spexin (SPX) is a peptide that plays an important role in the regulation of food intake and body weight (BW) by the effect on carbohydrate-lipid metabolism. However, the role of SPX in fetal life, in children, and in adolescent metabolism is limited. Therefore, we decided to check whether obesity affects the concentration of SPX in the mother's peripheral blood (MB) and umbilical cord blood (UCB). Using MB and UCB sera on the day of delivery obtained from 48 women (24 non-obese and 24 obese) and commercially available Elisa kits and colorimetric assays, we determined changes in SPX and the relationship between SPX concentration and other metabolic and anthropometric markers (body weight and BMI) on the day of delivery and in children at the age of 36 months. We found lower concentrations of SPX in MB (p < 0.05) and UCB (p < 0.01) derived from obese women (BMI > 30) and a moderate linear correlation (r = 0.4429; p < 0.01) between SPX concentrations in MB and UCB. We also noted that the concentration of SPX is not correlated with the child's body weight on the day of birth (r = -0.0128). However, there is a relationship between SPX at birth and body weight at 3 years of age (r = -0.3219; p < 0.05). Based on the obtained results, it can be assumed that spexin is one of the factors modulating the child's metabolism already in the fetal period and can be considered a potential marker of future predisposition to obesity. However, confirmation of this thesis requires additional research.

The effects of exercise training on insulin resistance in children and adolescents with overweight or obesity: a systematic review and meta-analysis.

The aim of present meta-analysis was to determine the effects of exercise training (Exe) on insulin resistance (IR) and body weight in children and adolescents with overweight or obesity. PubMed, Web of Science, and Scopus were searched for original articles, published through October 2022 that included exercise versus control interventions on fasting glucose, insulin, HOMA-IR, and body weight outcomes in children and adolescents with overweight or obesity. Standardized mean differences (SMD) for fasting insulin, and weighted mean differences (WMD) for fasting glucose, HOMA-IR, body weight (BW), and 95% confidence intervals were determined using random effects models. Thirty-five studies comprising 1,550 children and adolescents with overweight and obesity were included in the present meta-analysis. Exercise training reduced fasting glucose (WMD=-2.52 mg/dL, p=0.001), fasting insulin (SMD=-0.77, p=0.001), HOMA-IR (WMD=-0.82, p=0.001), and BW (WMD=-1.51 kg, p=0.001), as compared to a control. Subgroup analyses showed that biological sex, intervention duration, type of exercise training, BMI percentile, and health status (with or without diagnosed condition), were sources of heterogeneity. Exercise training is effective for lowering fasting glucose, fasting insulin, HOMA-IR, and BW in children and adolescents with overweight or obesity and could provide an important strategy for controlling IR and related factors. With clear evidence for the effectiveness of exercise interventions in this vulnerable population, it is important to determine effective approaches for increasing exercise training in children and adolescents with overweight or obesity.

Association and potential mediators between socioeconomic status and childhood obesity in China: findings from a national cohort study

ObjectiveSocioeconomic status (SES) is associated with childhood obesity, but the underlying factors remain unknown. This study aimed to identify mediators that may explain SES disparities in childhood obesity in China. MethodsNationally representative longitudinal data from the China Education Panel Survey of 11 019 children (13.03 ± 0.79) collected from 2013‒2014 to 2016‒2017 academic years. Overweight/obesity was defined using Chinese national body mass index cut-points. Principal component analysis was used to convert the four SES indicators (maternal and paternal education, and occupation) into one comprehensive variable. Mediation analysis for SES disparities in childhood obesity was conducted using structure equation models. ResultsThe prevalence of overweight/obesity was 12.8%, and was higher in boys than in girls (17.8% vs. 7.6%, P < 0.001) at baseline. Among boys, relative risk (RR) of obesity was 1.23 (95% CI: 1.09 to 1.40, P < 0.001) for per unit change in SES. There was no significant association between obesity and SES among girls. Mediation analyses showed that among boys, birth weight, being the only child in the family and children's self-perceived weight status mediated 70.0% of the effects of SES on obesity. No mediation effect was detected in girls. ConclusionsChinese boys are more likely to be overweight or obese than girls. SES may impact childhood obesity through birth weight, being the only child in the family and children's self-perceived body weight status in boys, but not in girls. More attention should be made to address childhood obesity in high SES families among boys. Interventions targeting at these mediators are needed.

Effectiveness and safety of intermittent preventive treatment with dihydroartemisinin–piperaquine or artesunate–amodiaquine for reducing malaria and related morbidities in schoolchildren in Tanzania: a randomised controlled trial

In high transmission settings, most school-aged children harbour malaria parasites without showing symptoms, often leading to anaemia and possibly impaired psychomotor and cognitive abilities. We aimed to assess the effectiveness and safety of intermittent preventive treatment for malaria in school-aged children (IPTsc) living in highly endemic areas. We did an open-label randomised controlled trial in seven primary schools in northeastern Tanzania. Schoolchildren aged 5-15 years were individually randomly assigned (1:1:1) to receive dihydroartemisinin-piperaquine, artesunate-amodiaquine, or standard of care (control) using a balanced block design. Drugs were administered by schoolteachers, with supervision from study nurses, at months 0 (baseline), 4, and 8, and were given in line with manufacturer's recommendations with dose based on the child's bodyweight. The primary endpoints were change from baseline in mean haemoglobin concentration at months 12 and 20, and clinical incidence of malaria and prevalence of parasitaemia at months 12 and 20 in the intervention groups versus the control group. The outcome data were collected through longitudinal surveys conducted every 4 months. Data were analysed on the basis of intention to treat (including all randomised participants) and per protocol (comprising children who completed the full 3-day regimen of all three IPTsc treatment rounds as assigned). This study is registered with ClinicalTrials.gov (NCT03640403). Of the 1797 children scheduled for clinical screening, 1566 were enrolled and randomly allocated (526 to receive dihydroartemisinin-piperaquine, 527 to receive artesunate-amodiaquine, and 513 to receive standard of care). Due to COVID-19-related school closures, only two schools were visited at month 12 (135 children in the dihydroartemisinin-piperaquine group, 131 in the artesunate-amodiaquine group, and 118 in the control group). At month 12, compared with the control group, the change from baseline in mean haemoglobin concentration was increased by 0·5 g/dL (95% CI 0·2 to 0·8; p<0·0001) in the dihydroartemisinin-piperaquine group and 0·5 g/dL (0·2 to 0·7; p=0·0020) in the artesunate-amodiaquine group in the intention-to-treat analysis (with similar findings in the per protocol analysis). In the same period, in the intention-to-treat analysis, the prevalence of malaria parasitaemia increased from 28·5% (138 of 485 participants) to 33·6% (39 of 116) in the control group, but decreased from 28·0% (139 of 497) to 12·0% (15 of 125) in the dihydroartemisinin-piperaquine group (-21·6 percentage points [95% CI -31·9 to -11·3], p=0·0001 vs control at month 12) and from 24·7% (124 of 502) to 16·0% (20 of 125) in the artesunate-amodiaquine group (-17·6 percentage points [-28·4 to -6·9], p=0·0015). The decrease for artesunate-amodiaquine was larger in the per protocol analysis (-25·3 percentage points [-36·3 to -14·2], p<0·0001). The protective effect of IPTsc against malaria parasitaemia was 64% (95% CI 39 to 79; p<0·0001) for dihydroartemisinin-piperaquine and 52% (23 to 70; p=0·0015) for artesunate-amodiaquine in the intention-to-treat analysis, and was slightly higher on per protocol analysis. The protective effect against clinical malaria at month 12 was 20% (95% CI 9 to 29; p=0·0002) for dihydroartemisinin-piperaquine and 19% (8 to 28; p=0·0004) for artesunate-amodiaquine. No significant differences in any primary outcomes between the intervention and control groups were noted at month 20. Dihydroartemisinin-piperaquine and artesunate-amodiaquine were associated with a small number of mild adverse events, and there were no treatment-related serious adverse events or deaths. IPTsc with dihydroartemisinin-piperaquine or artesunate-amodiaquine is a safe and effective approach to reducing malaria parasitaemia, clinical malaria, and related morbidities, and is feasible to implement through programmes delivered by schoolteachers.
