RESUMEN
Design-based STEM learning is believed to be an effective cross-disciplinary strategy for promoting children's cognitive development. Yet, its impact on executive functions, particularly for disadvantaged children, still need to be explored. This study investigated the effects of short-term intensive design-based STEM learning on executive function among left-behind children. Sixty-one Grade 4 students from a school dedicated to the left-behind children in China were sampled and randomly assigned to an experimental group (10.70 ± 0.47 years old, n = 30) or a control group (10.77 ± 0.43 years old, n = 31). The experimental group underwent a two-week design-based STEM training program, while the control group participated in a 2-week STEM-related reading program. Both groups were assessed with the brain activation from 4 brain regions of interest using functional near-infrared spectroscopy (fNIRS) and behavioral measures during a Stroop task before and after the training. Analysis disclosed: (i) a significant within-group time effect in the experimental group, with posttest brain activation in Brodmann Area 10 and 46 being notably lower during neutral and word conditions; (ii) a significant between-group difference at posttest, with the experimental group showing considerably lower brain activation in Brodmann Area 10 and Brodmann Area 46 than the control group; and (iii) a significant task effect in brain activity among the three conditions of the Stroop task. These findings indicated that this STEM learning effectively enhanced executive function in left-behind children. The discrepancy between the non-significant differences in behavioral performance and the significant ones in brain activation implies a compensatory mechanism in brain activation. This study enriches current theories about the impact of Science, Technology, Engineering, and Mathematics (STEM) learning on children's executive function development, providing biological evidence and valuable insights for educational curriculum design and assessment.

BACKGROUND: Previous research indicates the start of primary school (4-5-year-old) as an essential period for the development of children's physical activity (PA) patterns, as from this point, the age-related decline of PA is most often observed. During this period, young children are exposed to a wider variety of environmental- and social contexts and therefore their PA is influenced by more diverse factors. However, in order to understand children's daily PA patterns and identify relevant opportunities for PA promotion, it is important to further unravel in which (social) contexts throughout the day, PA of young children takes place. METHODS: We included a cross-national sample of 21 primary schools from the Startvaardig study. In total, 248 children provided valid accelerometer and global positioning (GPS) data. Geospatial analyses were conducted to quantify PA in (social) environments based on their school and home. Transport-related PA was evaluated using GPS speed-algorithms. PA was analysed at different environments, time-periods and for week- and weekend days separately. RESULTS: Children accumulated an average of 60 min of moderate-to-vigorous PA (MVPA), both during week- and weekend days. Schools contributed to approximately half of daily MVPA during weekdays. During weekends, environments within 100 m from home were important, as well as locations outside the home-school neighbourhood. Pedestrian trips contributed to almost half of the daily MVPA. CONCLUSIONS: We identified several social contexts relevant for children's daily MVPA. Schools have the potential to significantly contribute to young children's PA patterns and are therefore encouraged to systematically evaluate and implement parts of the school-system that stimulate PA and potentially also learning processes. Pedestrian trips also have substantial contribution to daily MVPA of young children, which highlights the importance of daily active transport in school- and parental routines.

OBJECTIVE: To explore what Australian primary school parents want to learn about food and nutrition to improve their children's eating behaviours, as well as the associations between parents' personal and demographic characteristics and their views regarding their food and nutrition knowledge needs. DESIGN: An online nationwide cross-sectional survey was conducted in 2021 using a mixed-methods approach. Logistic regression analysis was utilised to examine the relationship between parents' demographics, personal values and their views. Content analysis was performed using Leximancer. SETTING: Australia. PARTICIPANTS: Seven hundred and eighty-seven parents. RESULTS: Fifty-one per cent wanted to learn more about food and nutrition to improve their children's healthy eating habits, and 77% of those preferred schools to provide that information. Online/printed newsletters and YouTube were the most preferred methods for receiving food and nutrition related information. Higher universalism-concern value (concern for the welfare of those in the larger society and world) scores were positively associated parents' preference for schools to provide food and nutrition-related information. Parents with non-English-speaking backgrounds and younger parents were more likely to want to learn about food and nutrition. Parents wanted to learn more about encouraging healthy eating, ideas for the lunchbox, food labels and age-specific portion sizes and recommendations. CONCLUSIONS: Findings can inform public health educators and assist them in designing future food and nutrition education programmes and resources targeting primary school parents.

This study aimed to investigate the longitudinal association between theory of mind (ToM) and loneliness as well as the potential moderating effects of parenting style on this association. A total of 689 Chinese third-grade students (341 girls and 348 boys; Mage = 9.23 years, SD = 0.66) were recruited from eight primary schools and were followed from Grade 3 to Grade 5. These students reported their primary caregivers' parenting style in third grade and completed the same ToM task and loneliness questionnaire at each time point from Grade 3 to Grade 5. The study's results indicated a bidirectional relationship between ToM and loneliness, implying that children with less developed ToM abilities tend to feel lonelier and, conversely, that higher levels of loneliness are associated with lower ToM skills. Moreover, the study demonstrated that parenting style influenced the association between ToM and loneliness. Specifically, the impact of ToM at Grade 3 on reducing loneliness at Grade 4 was greater among children who experienced high levels of rejection from their caregivers compared with those with low levels of rejection. In addition, this study found that loneliness at Grade 3 had a greater influence on ToM at Grade 5 for children experiencing low levels of emotional warmth from their caregivers than for those who experienced high levels of emotional warmth. These findings highlight the significance of ToM as both a precursor and consequence of children's loneliness and emphasize the variation in these longitudinal relationships based on the parenting styles of primary caregivers.

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.

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.

INTRODUCTION: Head lice infestation remains a persistent public health concern among primary school children in resource-limited settings, affecting their well-being and academic performance. Despite previous studies, there is no consistent evidence on the prevalence and factors associated with head lice infestation. This study aimed to determine the prevalence and factors related to head lice infestation among primary school children in low and middle-income countries. METHODS: This review was conducted by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. Relevant electronic databases, including PubMed, Cochrane Library, Web of Science, Science Direct, AJOL, and Google Scholar, were used to retrieve articles. The study included only published articles written in English languages between December 01, 2014 to January 31, 2024 for studies reporting the prevalence of head lice infestation or associated factors among primary school children in low- and middle-income countries. This review has been registered on PROSPERO with Prospero registration number CRD42024506959. The heterogeneity of the data was evaluated using the I2 statistic. A meta-analysis was conducted using STATA 17 software, with a 95% confidence interval. Publication bias was evaluated using funnel plots and statistical tests, such as Egger's and Beggs's tests, to identify publication biases in the included studies. Meta-regression was also carried out to assess the source of publication of publication bias. RESULTS: The review included 39 studies involving 105,383 primary school children. The pooled prevalence of head lice infestation among primary school children in low- and middle-income countries was 19.96% (95% CI; 13.97, 25.95). This review also found out that being a girl was 3.71 times (AOR = 3.71; 95% CI: 1.22-11.26) more likely to have head lice infestation as compared to boys, while children with a previous history of infestation were 4.51 times (AOR = 4.51; 95% CI: 2.31-8.83) more likely to have head lice infestation as compared to their counterparts. CONCLUSION: The overall prevalence of head lice infestation among primary school children in low- and middle-income countries was found to be high. Female gender, children who had a previous history of infestation, and family size were significant predictors of head lice infestation. As a result, policymakers and program administrators should focus on the identified determinants.

Previous research has suggested that math anxiety may contribute to poor math performance by interfering with working memory. However, only a limited number of studies investigated the mediating role of working memory in the math anxiety-math performance link in school-aged children. Unlike math anxiety, ego-resiliency is a personality resource that promotes the management of challenges and has been positively associated with math performance and negatively with anxiety. Nevertheless, there is still limited understanding regarding the specific role of ego-resiliency in math learning and how it relates to math anxiety. This study aimed to investigate conjunctly the interplay between primary school children's ego-resiliency, math anxiety, working memory, and performance on two different math tasks (i.e., arithmetic task and word problem-solving task), after controlling for general anxiety and age. The study involved 185 Italian children from grades 3 to 5. Serial multi-mediational analyses revealed that: (1) ego-resiliency has a positive indirect effect on math achievement through two paths - math anxiety, and math anxiety and working memory; (2) the study replicated previous findings showing that working memory partially mediated the relationship between math anxiety and math performance; (3) similar patterns of results were found for both math skills. The study identifies ego-resiliency as a possible protective factor in the development of math anxiety and suggests that ego-resiliency could be worth considering when designing interventions aimed at reducing negative emotions towards mathematics.
RESUMEN
Ninety per cent of Australian school children bring a home-packed lunch to school, with 44% of the food consumed during school hours being unhealthy. Among other factors, cost is a key consideration for food provision; however, the costs to Australian families are not well understood. Therefore, we aimed to determine what families are currently paying for school lunchboxes in Australian primary schools and to examine associations between food costs and socio-demographic factors with dietary quality. An audit of local retail outlets was used to determine the food costs of lunchbox contents. Costs (AUD) were adjusted for inflation as of early 2023. The lunchboxes of 1026 children aged 4-12 years at 12 Catholic primary schools in New South Wales, Australia, were assessed at the start of the day, using photography assessment methods and a validated School Food Checklist. The mean cost of lunchbox contents was $4.48 AUD (SD 1.53), containing a mean energy of 2699 kJ (SD 859), with 37.3% (SD 23.9) of energy sourced from unhealthy foods. Multiple linear regression analyses found that the strongest predictors of higher lunchbox cost (Pâ <â 0.05) were a higher proportion of energy from unhealthy foods (Bâ =â 0.016) and lower Socio-Economic Indexes for Areas (B = -0.178), when controlling for child socio-demographics. The results indicated that lunchbox food costs to Australian families are comparable to alternative school food service models in Australia and internationally. Results demonstrate the cost of food is not the only barrier to providing a healthy school lunchbox. Demonstrating a need for cost-considerate systematic interventions addressing food provision challenges and socio-economic disparities faced by families.

BACKGROUND: This study aimed to explore the impact of the COVID-19 pandemic on capacity building for health promotion in primary schools from the perspectives of primary school teachers. METHODS: A cross-sectional observational study was conducted via an anonymous online survey between February and May 2022. Three-quarters (n2460) of all schools in the Republic of Ireland were invited to participate. Demographics such as gender, teaching experience, school type and delivering equality of opportunity in schools (DEIS) designation were collected. Perceived capacity for health promotion was measured on a 10-point Likert scale. Facilitators and barriers related to health promotion and aspects of child health prioritised for health promotion in the 2 years after restrictions eased were explored via closed- and open-ended questions. RESULTS: Of the 595 responses, 493 were eligible for analysis. Participants were based in schools in every county in the Republic of Ireland, with most (85.4%, n421) being female. Almost a third (30.5%, n150) were 11-20 years post-qualification, and a quarter (25.2%, n124) had over 30 years' teaching experience. Mean capacity for school-based health promotion pre-pandemic was moderate, at 6.6 ± 2.2 on a 10-point scale. Mean capacity in spring 2022 decreased significantly (p < 0.001) to 4.1 ± 2.4, indicating poor capacity. Capacity ratings did not significantly differ by school type (p = 0.31), socioeconomic designation (p = 0.27) or years post-qualification (p = 0.08). Capacity decrements were most frequently (49.7%, n245) attributed to organisational factors, while individual and community-level factors were cited by 27.6% (n136) and 21.5% (n106) of respondents, respectively. Healthy eating significantly (p < 0.001) decreased as a priority for health promotion between pre-pandemic times (76.3%, n376) and spring 2022 (23.1%, n114). Mental health significantly (p < 0.01) increased as a priority, being listed by 38.1% (n188) as a priority pre-pandemic and doubling to 72.6% (n358) in spring 2022. CONCLUSIONS: Fostering a holistic approach to health promotion in schools remains a challenge. Further efforts are needed to support schools to implement sustainable and balanced systems of health promotion.

This study endeavors to scrutinize the perspectives of primary school teachers regarding children's rights. Employing qualitative research methods, particularly a case study approach, the research delves into the insights of 14 teachers working in a primary school within the Turkish Cypriot region during the 2022-2023 academic year. Data collection was facilitated through the utilization of a semi-structured interview form, and subsequent analysis was conducted via content analysis. The findings underscore a discernible lack of adequate knowledge among teachers pertaining to children's rights, particularly in the context of violations occurring on social media platforms. In response, recommendations are posited, advocating for the implementation of in-service training programs to enhance teachers' awareness, the integration of children's rights throughout all stages of primary education, collaborative efforts between the Turkish Education Institution and the Information Technologies Communication Authority to raise awareness among families and educators, and the inclusion of a dedicated course on children's rights in the curriculum of the Turkish Cypriot Region Teacher Academy and university faculties of education.

This study examined the factors linked to low-threshold interprofessional collaboration in the context of Finnish primary schools. The main purpose of the study was to analyze how education and health and social care professionals perceived their mutual collaboration. The PINCOM-Q scale was used to identify factors related to interprofessional collaboration in professionals' work settings. The results indicate that individual factors such as work motivation and personal power are prominent in low-threshold collaboration. At the group level, communication has an important role to play in interprofessional collaboration. Professionals (n = 204) perceived mutual exchange of information as an important aspect of working together. The aspects that matter in the low-threshold mode of interprofessional collaboration are a complex combination of individual, group and less obvious organizational factors, all of which both reflect and are reflected in an individual's motivation and commitment to cooperation. The establishment of long-term and systematic low-threshold, interprofessional collaboration presupposes that individual interests are realized in good interaction in equal encounters between different organizational domains.

ISSUE ADDRESSED: This paper aims to explore Victoria parents' perceptions of their current practices and barriers in providing school lunches for their primary school children. METHODS: Respondents were asked via an online survey about their lunch provision practices, perceptions of the healthiness of school lunches, and barriers to providing healthy school lunches. Data were analysed using different statistical techniques: Chi-square test, Spearman correlation analysis, Mann-Whitney U test, and Kruskal-Wallis test. RESULTS: In total, 359 respondents completed the survey. Most respondents (84%) reported their child takes a home-packed lunch to school every day. Most respondents provided fruits (94%), vegetables (57%), and sandwiches (54%) every day for school lunches, whilst other core food items such as milk, meats, and legumes were provided less frequently. A substantial proportion of respondents provided some discretionary food items frequently (e.g., the proportion of respondents providing selected discretionary food items daily or 3-4 times/week: salty crackers-50%, sweet cookies/biscuits-40%, chips-20%). Respondents strongly agreed or agreed with several barriers; examples include not packing certain foods due to food spoilage concerns (50%) (school-related), the allocated time at their child's school is not enough to eat and enjoy school lunch (48%) (school-related), need more meal ideas (61%) (parent-related), healthy foods take more time to prepare (51%) (parent-related), and children request easy-to-eat food for school lunches (50%) (child-related). Core food score (an indicator of frequency of preparing/packing core food) was negatively correlated with parent-related and child-related barrier scores, whilst discretionary food score (an indicator of frequency of preparing/packing discretionary food) was positively correlated with these barrier scores. CONCLUSIONS: Overall, home-packed lunches remain the main option in primary schools in Victoria, and parents face several challenges in providing healthy lunches for their primary school children. SO WHAT?: The findings suggest the need for strategies from school leaders, education authorities, and policymakers to improve the quality of lunch content and address the barriers faced by parents.
RESUMEN
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.

Background: Childhood overweight and obesity represent serious public health concerns in several countries worldwide, including Italy, where the highest prevalence in Europe of overweight and obesity among primary school children was recorded. Among others, primary schools represent suitable social environments for health education projects. In this perspective, to optimize resources and plan successful activities, it is necessary, first of all, to analyze the context of the intervention. Study design: A pilot survey involving children and teachers was conducted in a primary school in Jesi (Le Marche Region, Italy). Methods: A questionnaire was submitted by teachers between May and June 2023 to 104 pupils (aged 6-11) from the five different primary school system classes. A qualitative questionnaire was also filled out by the same teachers (n = 5) who were present while the children were filling the eating/lifestyle questionnaire. Results: Most of the children (96.1%) had breakfast before school, with milk and cereal (51.5%) representing the preferred com-bination. During recess, 59.2% of pupils usually have a sandwich, 23.3% usually have sweet snacks, whereas only 2.9% have a fruit. Over 55% of the sample preferred drinking high-sugar beverages to water, and 15.5% declared going to a fast-food restaurant more than once a week. Over 17% of children did sport only once a week or less often. Over 64% of children habitually played videogames, and 77.6% normally watched TV or played with a tablet/smartphone while eating. Finally, the teachers' interview highlighted that there were no active health-related projects addressed to the pupils, and the school did not normally organize me-etings with health professionals to increase children's and their parents' knowledge and awareness about healthy eating habits. Conclusions: This preliminary investigation analyzed the context for a future health and nutrition education project and will assist researchers in planning successful activities and increasing the efficiency of the intervention.

OBJECTIVES: Our research aimed to examine children's sleeping habits from preschool to the end of elementary school age. Developing proper sleeping habits in childhood is essential, as it is decisive for the rest of our lives. METHODS: A total of 339 children (160 males and 179 females) took part in the research, of which 145 were preschool-age children (3-7 years old), 72 lower-grade elementary school children (6-11 years old), and 122 upper-grade elementary school children (12-16 years old). The questionnaire was completed in a paper form (elementary school students) and online (kindergarten children). RESULTS: The research results show that most of the children spend enough time sleeping following the recommendations. In case of the kindergarten children, the younger ones also sleep in the afternoon on weekends (average of 3.66 years, 28.3%), and the older ones do not sleep in the afternoon either in kindergarten during the week or at home at the weekend (average of 5.22 years, 46.2%). The use of blue light typically increases with age; 39% of the preschoolers, 61% of the 6-11-year-olds, and 67% of the 12-16-year-olds use it before falling asleep. Sleep aids and rituals are used by 87.6% of the preschoolers, 67.4% of the 6-11-year-olds, and 34.4% of the 12-16-year-olds, because significantly more preschoolers find it more difficult to fall asleep than older children. At night, 40% of the preschoolers wake up at least once (due to biological needs - 46.3%), 32% of the 6-11-year-olds wake up at night (due to nightmares - 42.3%), and 41% of the 12-16-year-olds also wake up all night (due to biological needs - 31.9%, and due to noise - 29.8%). CONCLUSION: Although the children get enough sleep, significantly more upper-grade school children feel tired in the morning. It is essential to help sleep and eliminate factors that prevent falling asleep to create a healthy circadian rhythm in the life of children.

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.
RESUMEN
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.
RESUMEN
Background: Although it is widely recognized that more attention needs to be paid to children's fluid intake, there is little information on how to improve it. Peer education has been suggested as an effective approach to changing health behaviors among school children. As a new approach, our study piloted a peer education program to improve children's fluid intake in primary schools. Methods: University students were prepared for their role as peer educators in an elective university course, including the concept of peer education and different pedagogical methods. The peer educators evaluated the training process by completing a questionnaire. The intervention took place during a School Health Day led by the peer educators. An anonymous survey with a questionnaire on knowledge of fluid intake was administered two weeks before, at the end of, and 15 weeks after the intervention. Changes in hydration knowledge were tested using repeated measures ANOVA. Results: The pilot program showed increased knowledge about fluid consumption (p < 0.001) in lower and upper primary school children (N = 326) at the end of the School Health Day compared to pre-intervention measures. A positive change was observed after 15 weeks only in upper primary students. Feedback from peer educators was useful for fine-tuning the program. Conclusions: This innovative program induced positive changes in knowledge about fluid intake in primary school children. The persistence of the changes differed between lower and upper primary school children. Based on the results, the intervention should be replicated to adapt the program to the needs of lower primary school children. Because the training of peer educators and the peer education program appeared to be successful, this program is worthy of international replication. This approach may also be suggested for other behavior change issues.
