Possible determinants of physical fitness in Japanese school children: A cross-sectional study.

BACKGROUND: Physical fitness is one of the most important health indicators in children. Although appropriate body composition or certain lifestyle factors such as frequent physical activity are thought to improve physical fitness, results of previous studies are inconsistent, and most studies were from Western countries. OBJECTIVES: We investigated associations of body composition and modifiable lifestyle factors such as physical activity, screen time, diet and sleep duration with physical fitness in Japanese primary school children. METHODS: 2308 children (age 10-12 years old) in 12 primary schools were analysed in this cross-sectional study. Physical fitness was evaluated by sports battery tests conducted routinely and annually at schools. The total score of sports battery tests, 20-m shuttle run (laps) and grip strength (kg) were selected as outcomes. Information about lifestyle factors was collected by two questionnaires. Associations between lifestyle factors and physical fitness were assessed by multivariable linear mixed models by sex. RESULTS: Frequent exercise was related to better overall physical fitness. Regarding the 20-m shuttle run, many unfavourable lifestyle factors such as higher BMI in boys (ß -7.37, 95% confidence interval [CI] -8.39, -6.35) and girls (ß -3.54, 95% CI -4.50, -2.58), longer screen time (ß -4.31, 95% CI -7.29, -1.34) in boys and girls (ß -5.65, 95% CI -9.01, -2.30); shortest (reference) versus longest, breakfast skipping in boys (ß -5.24, 95% CI -8.71, -1.77) and girls (ß -3.57, 95% CI -6.84, -0.30); consumers (reference) versus skippers were associated with worse performance. Better quality of diet was associated with better results in the 20-m shuttle run only in girls (ß 2.58, 95% CI 0.24, 4.93); lowest (reference) versus highest. CONCLUSIONS: Frequent exercise was related to better physical fitness. Higher BMI and unfavourable lifestyle factors such as longer screen time and breakfast skipping were associated with worse results of the 20-m shuttle run.

Effects of fancy rope-skipping on motor coordination and selective attention in children aged 7-9 years: a quasi-experimental study.

Introduction: Recent studies have emphasized the intricate connection between exercise and cognition, focusing on specific cognitive processes and their correlations with specific motor skills. However, research on the impact of the qualitative aspects of movement on both short- and long-term cognitive performance is limited. In this quasi-experimental study, we investigate the impact of a 10-week fancy rope-skipping intervention on motor coordination and selective attention of 7-9-year-old children. Methods: A total of 60 primary school students from Changbin School in Haikou participated and completed the study from October to December 2022. The 60 participants were divided into a fancy rope-skipping group and a control group. Children's motor coordination was assessed using the Körperkoordinations Test für Kinder (KTK), while selective attention was evaluated using the d2 Test of Attention. Children were assessed at baseline and after the 10-week intervention. Results: Compared with the control group, the scores for the total KTK and for the hopping for height, jumping sideways, and moving sideways sub-items were significantly higher in the rope-skipping group after the intervention, with a significant interaction effect between time and intervention. Attention concentration improved in the rope-skipping group and had a significant interaction effect between time and intervention compared with the control group; the effects of the intervention on other aspects of selective attention were unclear. Conclusions: Our study suggests that a 10-week fancy rope-skipping intervention may potentially enhance motor coordination and selective attention accuracy in children aged 7-9 years.

Prevalence of dental caries and associated factors among primary school children in Ethiopia: systematic review and meta-analysis.

BACKGROUND: Dental caries (decay or cavities) is the breakdown of teeth as a result of bacteria. Dental caries is one of the most preventable oral health problems and the most common chronic disease in primary school children. Poor dental and oral health affects the quality of children's lives. OBJECTIVES: The study aimed to synthesize the existing literature on the prevalence and associated factors of dental caries among primary school children in Ethiopia in 2024. METHODOLOGY: Studies were searched through the search engines of Google Scholar, PubMed, Scopus, MEDLINE, and the Cochrane Library. Searching was made using keywords and MeSH terms for dental caries, dental plaque, primary school children, and Ethiopia. Heterogeneity was assessed using the Cochran Q test and I2 statistics. A random-effects model with a 95% confidence interval was used for prevalence and odds ratio estimations. RESULT: The result of seven studies disclosed that the overall prevalence of dental caries in primary school children in Ethiopia was 35% (26-45%). high intake of sweets (OR = 2.71,95%CI:1.968-3.451), a poor habit of tooth cleaning (OR = 2.46; 95% CI: 2.761-5.045), Grade level 1-4(OR = 2.46; 95% CI: 1.523-3.397), having a history of toothache(OR = 2.99; 95% CI: 2.679-3.314), absence of toothpaste use(OR = 1.42; 95% CI: -1.278-4.109), reduction of the previous year's academic score(OR = 5.51; 95% CI: 1.952-9.066), had a significant microbial load(OR = 3.82, CI: 3.439-4.192) and have acid bacillary pH on their teeth(OR = 2.42, CI: 1.494-3.335) were independent variables associated with dental carries among primary school children. CONCLUSION: The overall prevalence of dental caries among primary school children in Ethiopia is 35%, ranging from 26 to 45%. However, variations in prevalence rates are observed based on sampling techniques. Studies using simple random sampling report a higher prevalence rate of 42%, while those employing multi-stage random sampling and systematic random sampling show lower rates of 30% and 35%, respectively. This indicates that the choice of sampling technique can impact reported prevalence rates, with simple random sampling yielding higher estimates compared to other methods.

The impact of family socioeconomic status on parental involvement and student engagement during COVID-19 in promoting academic achievement: A longitudinal study in Chinese children.

With a three-wave longitudinal design, the current study examined the impact of family socioeconomic status (SES) on parental involvement and student engagement in promoting children's academic achievement during the coronavirus disease 2019 (COVID-19) pandemic. We recruited data from 246 mother-primary school student dyads, and the mean age of children at Wave 1 was 10.57 ± 0.97 years (range = 9-13 years). The academic achievement of these children was measured both before and after school closures. Family SES, parental involvement, and student engagement were assessed during the school closures. The results indicated that family SES could predict children's later academic achievement after accounting for their prior academic achievement and other demographics (i.e., the significant total effect in the model). Moreover, parental involvement and student engagement played chain-mediating roles in the effect of family SES on children's later academic achievement. Neither parent involvement nor student involvement alone mediated the relationships between family SES and subsequent academic achievement. Suggestions are provided to minimize the negative impact of low family SES on children's academic achievement during pandemics.

Burden of Goitre and Urinary Iodine Status among Primary School Children in Kashmir, India-Evidence from a Population-Based Iodine Deficiency Disorder Survey.

Introduction: Iodine deficiency is the leading cause of preventable brain damage, with 30% of the world's population suffering from iodine deficiency disorders (IDDs). The objectives of the study are to estimate the prevalence of goitre among schoolchildren in the age group of 6-12 years, to find out the proportion of households with adequately iodised salt, and to assess the dietary iodine intake by measuring urinary iodine levels in the urine samples of school-going children. Methods: A cross-sectional study was conducted in four pre-selected districts of the Kashmir division of Jammu and Kashmir in school-going children aged 6 to 12 years. Multi-stage 30 cluster sampling was used to select the study sample. For the selection of 30 clusters in each district, probability proportional to size (PPS) was employed. From each cluster, 90 children were selected. From a sub-sample of children in each district, 540 salt samples and 270 urine samples were also collected. Results: A total of 10,800 children aged 6-12 years were examined. Grade I goitre was present in 1382 (12.8%) and 116 (1.07%) which were having Grade II goitre. The weighted prevalence of goitre for four districts was 12.6%, lowest for district Ganderbal and highest for district Shopian. Half of the population in all the districts consumed salt with iodine levels of <15 ppm. Urinary iodine levels <99.9 mg/L were present in 15.7% indicating mild to moderate iodine deficiency. Conclusion: Though the present survey showed some decline in the total goitre rate (TGR) from a prevalence of 14.8% in 2017 to 12.6% in 2022, it continues to be a public health problem of mild to moderate intensity in Kashmir. The salt consumed at the household level was inadequately iodised. Hence, efforts in IDD elimination activities need to be scaled up further with emphasis on iodised salt quality control and intensive education at the community level.

Relationship Between School Food Environment and Eating Behaviors of Primary School Children in Dodoma: A Cross-Sectional Study.

This cross-sectional study assesses the relationship between school food environment and eating behaviors of primary school children in Dodoma among 248 primary school children aged 6-13 years. School characteristics information and socio-demographic characteristics were collected. Multilevel modeling was employed to assess the individual-level variance in eating behaviors. Most of the variances in the investigated eating behaviors were at the personal level. Significant associations (p < .05) were between protein-rich food intake and fats and sugar-rich food with the death of either parent. And association between intake of vitamin and mineral-rich foods and the number of people living in household.

Effects of school nurse-led health education to reduce malnutrition among primary school children in Bangladesh: Cluster nonrandomized controlled trial.

Background: Malnutrition is a major health concern among children especially in low and middle-income countries. However, there are limited studies on school health in Bangladesh. This study aimed to reduce malnutrition among primary school children in Bangladesh by increasing awareness and knowledge through school nurse-led health education. Methods and Materials: A prospective, open-label, parallel-group (1:1), cluster nonrandomized controlled trial on primary school children conducted in rural Bangladesh. The study lasted 13 months between September 2021 and September 2022. Four schools were selected and assigned to the intervention and control groups (CGs). Next, school nurses provided evidence-based health education to the children in the intervention group (IG) for 9 months to improve awareness and knowledge of malnutrition. Data were collected at baseline, midline, and endline. Results: Overall, 604 children were enrolled at the baseline; among them, 455 (CG, n = 220; IG, n = 235) completed the study. Changes in the malnutrition rate-the primary outcome-were not significant (P = 0.225). However, after adjusting the endline data with baseline and sociodemographic data, the children's body mass index improved significantly in the IG than in the CG (P < 0.05). Changes in eating behavior, and awareness and knowledge of malnutrition-the secondary outcomes-significantly differed between the groups (P < 0.001). Conclusion: The school nurse-led health education program significantly improved primary school children's awareness and knowledge of malnutrition. This study revealed the effectiveness of school nurses in reducing malnutrition among children, which may decrease future morbidity and mortality rates in children.

The Relationship between Parental Autonomy Support and Children's Self-Concept in China-The Role of Basic Psychological Needs.

This study aimed to investigate the relationship between parental autonomy support and children's self-concept, and to explore the role of basic psychological needs in Chinese primary schools from the perspective of self-determination theory. A total of 3109 children aged 6-13 years participated in eastern China. The results indicated a significant correlation between parental autonomy support, basic psychological needs, and children's self-concept. Basic psychological needs play a partial mediating role between parental autonomy support and children's self-concept. Specifically, autonomy support varied by need types whereas parental control steadily played a negative predictive role. Parental autonomy support and control predicted children's self-concept differently through three basic psychological needs, with differences across gender and grades. Boys and elder children had stronger relationships to competence needs, while girls were sensitive to autonomy needs; in addition, both of them were sensitive to relatedness needs. The mediating effects model and cross-group analyses revealed the complex predictive role of parental autonomy support on children's self-concept in China, providing an effective entry point for cross-cultural research and family education to improve children's psychological well-being.

Preschool emergent literacy skills as predictors of reading and spelling in Grade 2 and the role of migration background in Germany.

Children's emergent literacy skills are essential for the development of later literacy abilities and school success. However, children with migration background often show poorer language skills in the majority language and are at a greater risk of developing literacy deficits. In addition, there is evidence for the predictive role of emergent literacy skills in reading comprehension, but there has been relatively little research concerning the association between preschool emergent literacy skills and word reading and spelling in Germany, especially for children with migration background. This study examines the associations of emergent literacy skills (vocabulary, phonological awareness [PA], letter knowledge, and rapid naming) with word reading and spelling from kindergarten to the end of Grade 2 and evaluates the role of migration background (i.e., use of the majority or minority language at home) in these associations. Data from 187 preschool children were obtained before school entry (Mage = 63.58 months, SD = 4.45). The results show that vocabulary and letter knowledge were strong predictors of word reading, whereas letter knowledge and PA were significant predictors of spelling. Furthermore, children's migration background was negatively associated with preschool vocabulary and PA. For children with migration background, vocabulary was a significant predictor of word reading, whereas letter knowledge was the best predictor of word reading for children without migration background. The results reflect the complexity of language development and the relevance of emergent literacy skills as predictors for word reading and spelling. Specific interventions should be developed to promote children's literacy abilities.

Prevalence of Sarcoptes scabiei infestation and its associated factors among primary school children: A school-based cross-sectional survey in the Rufiji district, Tanzania.

Objectives: This study aimed to investigate the prevalence of Sarcoptes scabiei infestation and its associated factors among primary school children (PSC) in the Rufiji district. Methods: A quantitative school-based cross-sectional study was conducted among 447 PSC in the Rufiji district. The prevalence of scabies among PSC was determined by clinical examination and by microscopic examination of skin samples for the presence of S. scabiei. A structured questionnaire was used to gather data on factors associated with S. scabiei infestation. Descriptive analysis, Fisher's exact, chi-square tests, and logistic regression analysis were used to analyze the data. Results: The prevalence of scabies was 2.0%. Of the assessed factors, only physical contact with a person having itchy skin lesions (Adjusted Odds Ratio [AOR]=4.04, 95%CI 4.39-12.50) and infrequency of changing clothes before laundry (AOR=2.99, 95%CI 1.35-4.94) were significantly associated with scabies. The majority of participants demonstrated low levels of knowledge, with half exhibiting poor attitudes and inappropriate healthcare-seeking behaviors. Conclusions: There was an ongoing transmission of scabies among PSC in the Rufiji district, with the factors associated with the transmission being physical contact with a person who had an itchy skin lesion and the infrequency of changing clothes before laundry. Therefore, there is a need for regular clinical screening and treatment of positive cases with preventive measures on contact and provision of health education.

The relationship between food habits and physical activity and the IQ of primary school children.

BACKGROUND: Children's intelligence quotient (IQ) is influenced by various environmental and genetic variables. The current study aimed to determine how children's dietary choices and physical activity levels correlated with their IQ. METHODS: A total of 190 students (111 girls and 79 boys) between the ages of 8 and 10 were chosen randomly for this cross-sectional research. For all children, questionnaires were utilized to gather information on their anthropometry, socio-economic position, food habits, and 24-h memory. Children's physical activity questionnaire (CPAQ) was also used to gauge their level of physical activity. Raven's color progressive intelligence test was also used to gauge children's IQ. All the questions may be filled out online with the assistance of parents. SPSS software was used to gather and evaluate the generated data. RESULTS: Of 190 respondents, 79 (41.6%) are males, and 111 (58.4%) are girls. The results of the study showed that, a positive correlation between children's IQ and physical activity (P = 0.017, r = 0.17), if this relationship was not seen by gender. In addition, a positive correlation was observed between the IQ and food habits scores in all children (P = 0.001, r = 0.24), as well as by gender, that is, male (P = 0.04, r = 0.23) and female (P = 0.006, r = 0.26), which indicates that children with better food habits were associated with higher IQ. CONCLUSION: It was shown that elementary school children's IQ, food habits, and degree of physical activity are all positively correlated.

Math attitudes and math anxiety predict students' perception of teacher support in primary school, but not vice versa.

BACKGROUND: Both teacher support and math attitudes have been identified as associated with math anxiety in primary school children. However, little is known about how they are interrelated longitudinally. AIMS: The study was designed to examine the associations among perceived teacher support, math attitudes, and math anxiety in Chinese primary school students. SAMPLE: The sample included 1802 students (56.16% boys) initially in the third and fourth grades in two public schools in China. METHODS: A three-year cross-lagged panel design was conducted to examine the associations among perceived teacher support, math attitudes, and math anxiety. Moreover, a multigroup analysis was used to examine whether the associations varied by gender. RESULTS: There were reciprocal associations over time between math attitudes and math anxiety. Meanwhile, both math attitudes and math anxiety significantly predicted perceived teacher support one year later, but not vice versa. Further, the association between T1 math anxiety and T3 perceived teacher support was mediated by T2 math attitudes; the association between T1 math attitudes and T3 perceived teacher support, on the other hand, was mediated by T2 math anxiety. Moreover, there were no significant gender differences in these associations. CONCLUSIONS: Math anxiety and math attitudes objectively affected each other, and both of them significantly predicted later perceived teacher support, but not vice versa. This study demonstrates that children are not merely passive recipients of environmental influences and offers theoretical guidance for intervention practices that aim to reduce the risk of math anxiety.

Physical Activity Levels During School Recess in a Nationally Representative Sample of 10- to 11-Year-Olds.

PURPOSE: School recess provides a valuable opportunity for children's daily moderate- to vigorous-intensity physical activity (MVPA). This study aimed to quantify MVPA during school recess in a representative sample of Scottish children and examine whether recess MVPA varied by gender, socioeconomic status, season, urban/rural residency, and recess length. METHOD: Five-day accelerometry MVPA data were analyzed from 773 children (53.9% girls, 46.1% boys, 10- to 11-y-olds) from 471 schools. Binary logistic regression explored associations between meeting/not meeting the recommendation to spend 40% of recess time in MVPA and the aforementioned risk factors. Descriptive recess data were also analyzed. RESULTS: Participants spent an average of 3.2 minutes (SD 2.1) in MVPA during recess. Girls engaged in 2.5 minutes (SD 1.7) of MVPA compared with 4.0 minutes (SD 2.2) for boys. Only 6% of children met the recess MVPA recommendation. The odds of girls (odds ratio 0.09; 95% confidence interval, 0.04-0.25) meeting the recommendation was lower (P < .001) compared with boys. No statistically significant differences were observed in meeting the recommendation for the other risk factors. CONCLUSION: Levels of MVPA during school recess are very low in Scottish children, and interventions aimed at increasing MVPA during recess are needed.

Nutritional status and prevalence of helminthic infection among primary school children in Bangladesh: A cross-sectional study.

AIM: Malnutrition and infectious diseases, such as helminthic infections, are widespread among primary school children, especially in low- and middle-income countries. However, there are limited studies on school health in Bangladesh, particularly in rural settings. This study aimed to explore the nutritional status and prevalence of helminthic infections in relation to associated health behavior, awareness, and knowledge regarding malnutrition and helminthic infections which were evaluated by school nurses among primary school children in Bangladesh. METHODS: This was a descriptive, cross-sectional survey study with a total duration of 1 month, from September to October, 2021. This study formed part of a school nurse project as a cluster non-randomized clinical trial in Bangladesh. Selected variables from that clinical trial were analyzed and reported in the results section. The study participants were primary school children from four schools in rural Bangladesh. RESULTS: In total, 604 children participated in the baseline survey and health checkups. Among them, 163 (27.0%) children were classified as malnourished according to the World Health Organization growth reference standard 2007. The prevalence of helminthic infections was 53 (8.8%). Approximately >50% of the children responded that they never/rarely practiced hygiene-related behaviors and had no awareness and knowledge regarding malnutrition and helminthic infections. However, differences between the variables were not statistically significant. CONCLUSION: Children's nutritional status and prevalence of helminthic infections with related deprived health behaviors, and minimal awareness and knowledge, reinforce the importance of implementing educational interventions in the future.

Trajectories of spherical equivalent refraction from grades 1 to 4 in Chinese children.

BACKGROUND: The development trajectories of children's SER remain unknown. This study aimed to characterize spherical equivalent refraction (SER) trajectories during grades 1-4 in Chinese children. METHODS: This prospective cohort study included 1226 first-grade non-myopic children from 12 public primary schools, randomly selected in two districts in Guangzhou, China. From November 2018 to March 2022, four-wave ocular examinations and questionnaire surveys have been completed. The group-based trajectory modeling was used to explore SER trajectories in grades 1-4. RESULTS: All five trajectories showed an upward trend and rose faster after grade 2. Children in the sharp-developing (n = 44), high-developing (n = 136), and rapid-developing (n = 237) myopia groups developed myopia before grades 2, 3, and 4, respectively. Their SER development speed remained at a relatively high level after myopia, almost consistent with that before myopia. Children in the moderate-developing (n = 418) and low-developing (n = 391) non-myopia groups did not develop myopia before grade 4. Some characteristics in grade 1 were independently associated with SER trajectories, including sex, axial length, number of parents with myopia, residence, academic achievement, and the duration of outdoor activity. Based on the baseline characteristics, we established the model predicting the probability of children belonging to each group. CONCLUSIONS: Myopia interventions are best started in grade 1 or preschool age. If interventions are not taken in time, the latest intervention window might be in grades 1, 2, and 3 for children with a high probability of belonging to the sharp-developing, high-developing, and rapid-developing myopia groups, respectively. The above probabilities might be predicted using the model we established. Moreover, the interventions for myopic children shouldn't be ignored.

Evaluating the effect of cow's milk fortified with albumin powder on malnutrition and anthropometric indices in primary-school children with mild-to-moderate underweight: A randomized double-blinded clinical trial.

Background: A proper diet plan is one of the necessary conditions for maintaining the children's health. The aim of this study was to evaluate the effect of consumption of pasteurized cow's milk fortified with albumin protein in primary-school children, in Yasuj, Iran. Materials and Methods: In this double-blind randomized clinical trial with 12 weeks of duration, 60 children aged 7-13 years, mild to moderate underweight (-1≥ weight-for-age z-score ≥-3), were randomly assigned to control and albumin groups. The albumin group and the control group received 200 cc of milk with 10 g of albumin powder and 200 cc of milk with 10 g of cornstarch powder, respectively. At the beginning and end of the study, food intake and anthropometric indices were measured. Results: After 12 weeks of intervention, none of the anthropometric indices (weight, weight-for-age z-score, body mass index (BMI), BMI-for-age z-score, and waist circumference) showed significant changes as compared to baseline in the control group, but weight-for-age z-score and BMI-for-age z-score showed significant increase as compared to baseline in the albumin group (before: -2.25 ± 0.40, after: -1.98 ± 0.35, P = 0.001 and before: -3.48 ± 0.86, after: -3.06 ± 0.71, P = 0.009, respectively). The comparison of the mean changes between the two groups showed significant difference regarding weight-for-age z-score (control group: -1.70 ± 0.31 in comparison with albumin group: -1.98 ± 0.35, P = 0.002), BMI (control group: 12.08 ± 1.96 in comparison with albumin group: 12.13 ± 1.49, P = 0.03), and BMI-for-age z-score (control group: -3.11 ± 0.91 in comparison with albumin group: -3.06 ± 0.71, P = 0.02). Conclusion: The consumption of albumin powder with milk can improve weight-for-age z-score and BMI-for-age z-score indices in children with mild-to-moderate underweight. Larger controlled interventional studies with longer duration are recommended.

Comparison of Malnutrition Indicators and Associated Socio-Demographic Factors among Children in Rural and Urban Public Primary Schools in South Africa.

Most children in South Africa attending public schools are predisposed to malnutrition due to poor infrastructure and social inequality. This is despite the implementation of the National School Nutrition Programme to address barriers to learning associated with hunger and malnutrition and the National Development Plan to reduce child malnutrition through provision of social grants. In view of this, we compared malnutrition indicators and associated socio-demographic factors among children in rural Mpumalanga and urban Gauteng in South African public primary schools selected using a multistage cluster random sampling. A validated researcher-administered questionnaire was used to collect socio-demographic data of caregivers, along with primary school children data collected on age, sex, learning grade, and anthropometric measures. Malnutrition indicators, which are stunting (low height-for-age z-scores), underweight (low weight-for-age z-scores), thinness (low body-mass-index-for-age z-scores), and overweight/obesity (high body mass index) were computed using WHO Anthro Plus 1.0.4 and data were analyzed using Stata 18. A total of 903 children (rural = 390 and urban = 513) with a mean age of 10 ± 2 years in the foundation phase (learning grades one to three) and the intermediate learning phase (learning grades four to seven) participated with their caregivers (mean age: 39 ± 8 years). Significant levels of poor socio-demographic status were observed among caregivers living in the rural setting compared to in the urban setting. Overall, thinness (18%), stunting (12%), underweight (10%), and overweight/obesity (24%) were observed among school children. Children in the rural schools had a significantly higher prevalence of stunting (20% vs. 3%; p < 0.0001), underweight (17% vs. 2%; p < 0.0001) and thinness (28% vs. 7%; p < 0.001) than their urban counterparts. In the urban, the odds of stunting, underweight and thinness were less among school children, while overweight/obesity was twice as likely in the urban setting. The multivariate final model showed lower odds of underweight [adjusted odds ratio (AOR) = 0.16; 95% confidence interval (CI): 0.06-0.42] and stunting [AOR = 0.33; 95% CI: 0.13-0.87] in the urban compared to the rural schools. The association of stunting with sex [AOR =0.53; 95% CI: 0.30-0.94] and the intermediate learning phase [AOR = 7.87; 95% CI: 4.48-13.82] was observed in the rural setting, while thinness was associated with living in households with an income of USD 52.51 to USD 262.60/month [AOR = 2.89; 95% CI: 1.01-8.24] and receiving the child social grant [AOR = 2.49; 0.90-6.86] in the urban setting. Overweight/obesity was associated with living in a household with an income of USD 52.51 to USD 262.60/month [AOR = 1.80; 95% CI: 1.02-3.10]. The findings suggest nutritional intervention approaches that are accustomed to the context of settings to effectively tackle malnutrition.

The Effect of Online-Delivered Guided Imagery Relaxation on Stress and Well-Being of Primary School Children.

Background: In the context of the coronavirus (COVID-19) pandemic, effectively coping with daily stressors is crucial for children who experience restrictions on physical movement and social activities. We examined the effects of the online-delivered guided imagery relaxation (GIR) technique on the stress and well-being of primary school children. Methods: Thirty-four (N = 34) 11-year-old students were randomly assigned to either intervention (n = 17) or waitlist-control (n = 17) groups. The participants from the intervention group were required to attend a 4-week online GIR session and practice the techniques daily for 5 min-10 min. The Stress in Children (SiC) questionnaire, the Strengths and Difficulties Questionnaire-Parent Reported (SDQ-PR) and tracking form were administered pre- and post-intervention. Results: Eleven (64.7%) participants attended all sessions and eight (47.0%) completed daily practices. Mixed-model ANOVA indicated no significant difference between participants from intervention and waitlist-control groups across pre- and post-intervention time points, with P-values greater than 0.05 for stress and well-being. Conclusion: Issues regarding online intervention, including managing children's activities from a distance, Internet connectivity, and time limitations might have affected their adherence and the research outcome. Nonetheless, the online-delivered GIR technique is a promising intervention modality. However, its implementation should be improvised to be more impactful.

Intelligence, motoric and psychological outcomes in children from different ART treatments: a systematic review and meta-analysis.

BACKGROUND: Subtle abnormalities in children's intelligence, motor skills, and psychology from various assisted reproductive treatments (ARTs) might be underdiagnosed. Understanding the prognosis of intelligence, motor skills, and psychology in children from ART would provide parents with reasonable expectations and enable them to plan relevant support to achieve the optimum potential in ART children. METHODS: We searched PubMed, EMBASE, Ovid, Google Scholar, and Scopus databases until April 13, 2021, to identify relevant studies. Thirty-four studies met the inclusion and exclusion criteria. The meta-analysis employed a standardized mean difference model. The outcome of this study is to compare intelligence quotient (IQ), motoric ability, and behavioral problems between all ARTs, in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI) to naturally conceived (NC) children. Subdomains of intelligence based on the Cattell, Horn, and Carroll Model (CHC Model) of cognitive architecture, including fluid reasoning, short-term and working memory, processing speed, visual-spatial ability, long-term memory retrieval, and crystalized intelligence (knowledge), were evaluated and summarized in details. Motor skill was stratified into two domains: gross motoric and fine motoric. Behavioral problem was categorized as externalizing and internalizing behavior. RESULTS: Meta-analysis showed that verbal intelligence score in IVF toddlers is significantly lower than NC toddlers (p = 0.02); conversely, ICSI toddlers scored significantly higher verbal intelligence score compared to NC toddlers (p = 0.005). Toddlers born after ART had significantly lower non-verbal intelligence score (p = 0.047). IVF toddlers scored significantly lower fine motor score (p = 0.01) compared to naturally conceived toddlers. Based on parent's CBCL, NC toddlers had higher total (p = 0.01) and externalizing behavior (p = 0.001) scores  compared to ART toddlers. Evaluation of full scale IQ and all domains of intelligence in preschool and primary school children revealed that no significant differences exist between ART and NC children. Based on preschool and primary school parents' CBCL, IVF children had significantly lower externalizing behavior score compared to NC children (p = 0.04). Meta-analyses of studies on young adolescents revealed that ART young adolescents scored higher academically than their NC counterparts, including on mathematics (p < 0.00001) and reading or language (p < 0.00001). CONCLUSIONS: Despite differences in certain aspects, this finding suggests that ART is unlikely to cause negative impacts on children's neurodevelopment.

Influence of Lexical Development on Reading and Spelling Skills: Effects of Enhancement on Second-Grade Children in Primary School.

Previous studies suggest that lexical competence is an important factor that influences reading skills and spelling accuracy in primary school children. Understanding the relationship between these skills will provide valuable insights to improve reading and writing enhancement and intervention strategies. The aim of this pre-post longitudinal study is to examine the effectiveness of an enhancement program, in which there are activities proposed through a narrative and metacognitive methodology, designed to develop the cognitive processes of lexical acquisition and its effects on reading and writing ability. A total of 74 primary school children (M-age = 7.04 years) participated in the research. They were divided into groups: experimental, which carried out the enhancement, and control groups, which carried out the typical school program. The results show that children who carried out the enhancement obtained higher scores in reading skills, specifically in reading accuracy and text comprehension and spelling accuracy, in comparison with their peers in the control group. These results suggest that strengthening the lexical semantic pathway, as theorized by Coltheart's two-way model, can lead to improved reading comprehension and diminished reading errors and spelling inaccuracies.
