Effects of a healthcare students’ prevention intervention for school children on their own substance use: a before-after study

BackgroundCognitive dissonance theory and research has suggested that engaging in prevention interventions for other students may be a means of reducing one’s own problematic behaviors in order to reduce potential cognitive dissonance. This study assessed the effects of a new mandatory prevention intervention program for healthcare students in France. The aim was to measure the effects of engaging in a prevention program in schools on the usual increase in substance use in student populations.MethodsHealthcare students were trained in a French university to develop psychosocial competences as a health promotion means (FEPS training) or more specifically to prevent substance use in teenagers (Unplugged program training). The students (n = 314) who accepted to take part in the study from both groups completed questionnaires before their interventions in schools, and at the end of the year, measuring their representations and behaviors regarding psychoactive substances.ResultsThe results indicated a significant reduction in alcohol consumption in terms of quantity, but no significant reduction in tobacco and marijuana consumption.ConclusionsThis study showed that, contrary to the usual increase in substance use in students as they advance in their year, the students who took part in this study showed reduced self-reported consumption of alcohol after they had performed the prevention intervention in schools regardless of the type of training they had received (general health promotion vs. specific substance use prevention program). Limitations and future perspectives are discussed.

The effects of height-for-age and HIV on cognitive development of school-aged children in Nairobi, Kenya: a structural equation modelling analysis.

Empirical evidence indicates that both HIV infection and stunting impede cognitive functions of school-going children. However, there is less evidence on how these two risk factors amplify each other's negative effects. This study aimed to examine the direct effects of stunting on cognitive outcomes and the extent to which stunting (partially) mediates the effects of HIV, age, and gender on cognitive outcomes. We applied structural equation modelling to cross-sectional data from 328 children living with HIV and 260 children living without HIV aged 6-14 years from Nairobi, Kenya to test the mediating effect of stunting and predictive effects of HIV, age, and gender on cognitive latent variables flexibility, fluency, reasoning, and verbal memory. The model predicting the cognitive outcomes fitted well (RMSEA = 0.041, CFI = 0.966, χ2 = 154.29, DF = 77, p < 0.001). Height-for-age (a continuous indicator of stunting) predicted fluency (β = 0.14) and reasoning (β = 0.16). HIV predicted height-for-age (β = -0.24) and showed direct effects on reasoning (β = -0.66), fluency (β = -0.34), flexibility (β = 0.26), and verbal memory (β = -0.22), highlighting that the effect of HIV on cognitive variables was partly mediated by height-for-age. In this study, we found evidence that stunting partly explains the effects of HIV on cognitive outcomes. The model suggests there is urgency to develop targeted preventative and rehabilitative nutritional interventions for school children with HIV as part of a comprehensive set of interventions to improve cognitive functioning in this high-risk group of children. Being infected or having been born to a mother who is HIV positive poses a risk to normal child development.

Normative cognition and the effects of a probiotic food intervention in first grade children in Côte d’Ivoire

The cognitive skills critical for success have largely been studied in Western populations, despite the fact that children in low- and middle-income countries are at risk to not reach their full developmental potential. Moreover, scientists should leverage recent discovery to explore means of boosting cognition in at-risk populations. This semi-randomized controlled trial examined normative cognitive development and whether it could be enhanced by consumption of a probiotic food in a sample of 251 4- to 7-year-old children in urban schools in Côte d’Ivoire. Participants completed executive functioning measures at baseline (T1) and 5 months later (T2). After T1, children in one school received a probiotic (N = 74) or placebo (N = 79) fermented dairy food every day they were in school for one semester; children in the other school (N = 98) continued their diet as usual. Children improved on all tests across time (Cohen’s d = 0.08–0.30). The effects of probiotic ingestion were inconclusive and are interpreted with caution due to socio-political factors affecting daily administration. Given the general feasibility of the study, we hope that it will serve as an inspiration for future research into child development and sustainable (health-promoting) interventions for school children in developing nations.

Process Evaluation of an Application-Based Salt Reduction Intervention in School Children and Their Families (AppSalt) in China: A Mixed-Methods Study.

BackgroundSalt reduction is a cost-effective, and rather challenging public health strategy for controlling chronic diseases. The AppSalt program is a school-based multi-component mobile health (mhealth) salt reduction program designed to tackle the high salt intake in China. This mixed-methods process evaluation was conducted to investigate the implementation of this program across sites, identify factors associated with the implementation, and collect evidence to optimize the intervention design for future scale-up.MethodsMixed methods were used sequentially to collect data regarding five process evaluation dimensions: fidelity, dose delivered, dose received, reach, and context. Quantitative data were collected during the intervention process. Participation rate of intervention activities was calculated and compared across cities. The quantitative data was used for the selection of representative intervention participants for the qualitative interviews. Qualitative data were collected in face-to-face semi-structured interviews with purposively selected students (n = 33), adult family members (n = 33), teachers (n = 9), heads of schools (n = 9), key informants from local health, and education departments (n = 8). Thematic analysis technique was applied to analyze the interview transcripts using NVivo. The qualitative data were triangulated with the quantitative data during the interpretation phase.ResultsThe total number of families recruited for the intervention was 1,124. The overall retention rate of the AppSalt program was 97%. The intervention was implemented to a high level of fidelity against the protocol. About 80% of intervention participants completed all the app-based salt reduction courses, with a significant difference across the three cities (Shijiazhuang: 95%; Luzhou: 73%; Yueyang: 64%). The smartphone app in this program was perceived as a feasible and engaging health education tool by most intervention participants and key stakeholders. Through the interviews with participants and key stakeholders, we identified some barriers to implementing this program at primary schools, including the left-behind children who usually live with their grandparents and have limited access of smartphones; perceived adverse effects of smartphones on children (e.g., eyesight damage); and overlooked health education curriculum at Chinese primary schools.ConclusionThis process evaluation demonstrated the feasibility and acceptability of using smartphone applications delivered through the education system to engage families in China to reduce excessive salt intake.Clinical Trial RegistrationThe AppSalt study was registered at www.chictr.org.cn, identifier: ChiCTR1800017553.

Pediatric Mental Health Treatment and Confidence through the Lens of the School Based Occupational Therapist’s Role

Given the rise in mental health needs in children and adolescents and the historical roots of occupational therapy in psychiatry, occupational therapists may be well-equipped and well-suited to offer expert contributions on school-based mental health teams. Occupation-based assessments and interventions for schoolchildren with mental health conditions are essential but are often overlooked because occupational therapy is traditionally solicited to support children with physical health concerns. The research problem for this study was that it was unclear how school-based occupational therapists perceive pediatric mental health treatment preparedness and confidence. The purpose of this basic qualitative study was to explore school-based occupational therapists’ perceptions of their preparedness and confidence to offer pediatric mental health treatment. Semistructured interviews were conducted through video conferencing. Self-efficacy and adult learning theories were used as guiding frameworks. Results of thematic analysis exposed five themes: the importance of university and fieldwork education; professional self-directness and intrinsic motivation; readiness to learn and role clarity; collaboration and communication; and advocacy. These findings have significant implications for occupational therapy students as well as their educators and employers.

The effectiveness of a high‐intensity interval games intervention in schoolchildren: A cluster‐randomized trial

The aim of this study was to assess the effectiveness of a high-intensity interval training (HIIT) intervention based on playground games (MOVI-daFit!) on improvements in adiposity, physical fitness, and cardiometabolic risk factors in schoolchildren. A cluster-randomized controlled trial (RCT) was performed that included 562schoolchildren (9-11years) from 10schools in Cuenca, Spain. The intervention consisted of four 60-min sessions per week in the school setting. Analyses were conducted on the intention-to-treat basis. Changes in physical fitness parameters (cardiorespiratory fitness: main outcome), body composition, blood pressure, and biochemical cardiometabolic risk parameters were analyzed using both mixed linear and logistic regression models, controlling for baseline covariates, Tanner stages, health dietary score index, body mass index, and cluster factor school. In boys, no significant differences in any outcome measure were noted except for the standing long jump test (10.13cm; 95% CI 2.94 to 17.32; p=0.006) between the intervention group (IG) and the control group (CG). Improvements in mean arterial pressure (-1.68mmHg; 95% CI -3.28 to -0.08; p=0.039), the triglyceride/HDL-c ratio (-0.36mg/dl; 95% CI -0.59 to -0.13; p=0.002), C-reactive protein (-0.23mg/L; 95% CI -0.43 to -0.03), VO2 max (1.44ml/kg/min; 95% CI 0.52 to 2.36, p=0.002), 20-m shuttle run test (3.64laps; 95% CI 0.51 to 6.78), and standing long jump test (7.04cm; 95% CI 1.21 to 12.87; p=0.018) were observed in girls in the IG compared with those in the CG. Body composition parameters did not change significantly in either boys or girls. Additionally, children with lower fitness levels obtained greater improvements than children with higher fitness levels. In conclusion, MOVI-daFit! may represent a good strategy for incorporating HIIT into playground games, although its implementation may need to be improved to extend the benefits to children and enhance its adherence.

Preventive Digital Mental Health for Children in Primary Schools: Acceptability and Feasibility Study.

BackgroundThe incidence of mental health problems in children and adolescents in the United Kingdom has significantly increased in recent years, and more people are in contact with mental health services in Greater Manchester than in other parts of the country. Children and young people spend most of their time at school and with teachers. Therefore, schools and other educational settings may be ideal environments in which to identify those experiencing or those at the risk of developing psychological symptoms and provide timely support for children most at risk of mental health or related problems.ObjectiveThis study aims to test the feasibility of embedding a low-cost, scalable, and innovative digital mental health intervention in schools in the Greater Manchester area.MethodsTwo components of a 6-week digital intervention were implemented in a primary school in Greater Manchester: Lexplore, a reading assessment using eye-tracking technology to assess reading ability and detect early atypicality, and Lincus, a digital support and well-being monitoring platform.ResultsOf the 115 children approached, 34 (29.6%) consented and took part; of these 34 children, all 34 (100%) completed the baseline Lexplore assessment, and 30 (88%) completed the follow-up. In addition, most children were classified by Lincus as regular (≥1 per week) survey users. Overall, the teaching staff and children found both components of the digital intervention engaging, usable, feasible, and acceptable. Despite the widespread enthusiasm and recognition of the potential added value from staff, we met significant implementation barriers.ConclusionsThis study explored the acceptability and feasibility of a digital mental health intervention for schoolchildren. Further work is needed to evaluate the effectiveness of the digital intervention and to understand whether the assessment of reading atypicality using Lexplore can identify those who require additional help and whether they can also be supported by Lincus. This study provides high-quality pilot data and highlights the potential benefits of implementing digital assessment and mental health support tools in a primary school setting.

Three-Year Intervention Effects on Food and Beverage Intake-Results from the Quasi-Experimental Copenhagen School Child Intervention Study (CoSCIS).

The diet of Danish children is often not in accordance with dietary guidelines. We aimed to evaluate changes in the intake of selected foods and beverages during a multi-component school-based physical activity intervention, and to investigate if changes were modified by socioeconomic status (SES). The study included 307 children (intervention group: 184; comparison group: 123) with information on dietary intake pre- and post-intervention as well as on SES. Linear regression models were conducted to assess the effect of the intervention on changes in dietary factors. Children from the intervention group increased their intake of whole-grain bread during the intervention (group means: 6.1 g/d (95% CI: 2.2 to 10.0) vs. 0.3 g/d (95% CI: −3.1 to 3.7) in the comparison group, p = 0.04). A significant interaction between SES and group allocation was observed to change in fruit intake (p = 0.01). Among children from low SES families, only those from the comparison group decreased their fruit intake (group means: −40.0 g/d (95% CI: −56.0 to −23.9) vs. 9.3 g/d (95% CI: −16.1 to 94) in the intervention group, p = 0.006). The present study found no convincing effect of introducing a multi-component intervention on dietary intake except a small beneficial effect on whole-grain bread consumption. However, beneficial intervention effects in fruit intake were found particularly among children from low SES families.

Metabolomics profiles associated with an organic diet intervention in school children in Limassol, Cyprus: A cluster-randomized cross-over trial

BACKGROUND AND AIM: Exposure to pesticides has been associated with oxidative stress in animals and humans. Previously, we showed that an organic food intervention reduced pesticide exposure and oxidative damage biomarkers over time, however associated metabolic changes are not fully understood yet. We assessed perturbations of the urine metabolome in response to an organic food intervention for children and its association with pesticides biomarkers [3-phenoxybenzoic acid (3-PBA) and 6-chloronicotinic acid (6-CN)]. We also evaluated the molecular signatures of metabolites associated with biomarkers of oxidative damage (OD) (8-iso-PGF2a and 8-OHdG) and related biological pathways. METHODS: We used data from the ORGANIKO LIFE+ trial (NCT02998203), a cluster-randomized cross-over trial conducted among primary school children in Cyprus. Participants (n=149) were asked to follow an organic food intervention for 40 days and their usual food habits for another 40 days, providing up to six first morning urine samples (850 samples in total). Untargeted GC-MS metabolomics analysis was performed. Metabolites with RSD≤20% and D-ratio≤50% were retained for analysis. Associations were examined using mixed-effect regression models and corrected for false-discovery rate of 0.05. Pathway analysis followed. RESULTS:Following strict quality checks, 156 features remained out of a total of 610. D-glucose was associated with the organic food intervention (β=-0.23, 95% CI: -0.37,-0.10), aminomalonic acid with the organic food intervention (β=-0.44, 95% CI:-0.68,-0.19) and the two OD biomarkers (β=-0.27, 95% CI:-0.34,-0.20 for 8-iso-PGF2a and β=0.19, 95% CI:0.11,0.28 for 8-OHdG) and uric acid with 8-OHdG (β=0.19, 95% CI:0.11,0.26). The most affected pathways were the starch and sucrose metabolism and pentose and glucuronate interconversions. CONCLUSIONS:Changes in the metabolomic profile of primary school children following a 40-day long systematic organic food intervention were observed. This is the first study providing evidence of differential expression of metabolites by an organic food intervention, corroborating the reduction in biomarkers of oxidative damage using metabolomics. KEYWORDS: organic food, metabolomics, pesticides, cluster randomized trial, oxidative stress, lipid damage

Evaluating Delivery of a CBT-Based Group Intervention for Schoolchildren With Emotional Problems: Examining the Reliability and Applicability of a Video-Based Adherence and Competence Measure.

Adherence and competence are essential parts of program fidelity and having adequate measures to assess these constructs is important. The Competence and Adherence Scale for Cognitive Behavioral Therapy (CAS CBT) was developed to evaluate the delivery of cognitive therapies for children with clinical anxiety. The present study is an assessment of the slightly adapted version of the CAS CBT evaluating the delivery of a Cognitive Behavioral Therapy (CBT)-based preventive group intervention: EMOTION: Kids Coping with Anxiety and Depression. This study was part of a Norwegian cluster randomized controlled trial (cRCT) investigating the effectiveness of a transdiagnostic intervention, the EMOTION program—an indicated prevention program targeting anxious and depressive symptoms. The applicability and psychometric properties of the CAS CBT were explored. Results are based on six raters evaluating 239 video-recorded sessions of the EMOTION program being delivered by 68 trained group leaders from different municipal services. Interrater reliability (intraclass correlation coefficients, ICC [3, 1]) indicated fair to good agreement between raters. Internal consistency of the instrument's key domains was calculated using the Omega coefficient which ranged between 0.70 to 0.94. There was a strong association between the two scales Adherence and Competence, and inter-item correlations were high across the items, except for the items rating the adherence to the session goals. Competence and Adherence Scale for Cognitive Behavioral Therapy is a brief measure for use in first-line services, with some promising features for easily assessing program fidelity, but some of the results indicated that the instrument should be improved. Future attention should also be made to adapt the instrument to fit better within a group setting, especially regarding evaluation of session goals. More research on how to adequately evaluate fidelity measures are also warranted.Clinical Trial Registration: www.ClinicalTrials.gov, identifier: NCT02340637.

A cost-effectiveness analysis of community water fluoridation for schoolchildren

BackgroundCommunity water fluoridation (CWF), the controlled addition of fluoride to the water supply for the prevention of dental caries (tooth decay), is considered a safe and effective public health intervention. The Republic of Ireland (Ireland) is the only country in Europe with a legislative mandate for the fluoridation of the public water supply, a key component of its oral health policy. However, more recently, there has been an increase in public concern around the relevance of the intervention given the current environment of multiple fluoride sources and a reported increase in the prevalence of enamel fluorosis. The aim of this economic analysis is to provide evidence to inform policy decisions on whether the continued public investment in community water fluoridation remains justified under these altered circumstances.MethodsFollowing traditional methods of economic evaluation and using epidemiological data from a representative sample of 5-, 8-, and 12-year-old schoolchildren, this cost-effectiveness analysis, conducted from the health-payer perspective, compared the incremental costs and consequences associated with the CWF intervention to no intervention for schoolchildren living in Ireland in 2017. A probabilistic model was developed to simulate the potential lifetime treatment savings associated with the schoolchildren’s exposure to the intervention for one year.ResultsIn 2017, approximately 71% of people living in Ireland had access to a publicly provided fluoridated water supply at an average per capita cost to the state of €2.15. The total cost of CWF provision to 5-, 8-, and 12-year-old schoolchildren (n = 148,910) was estimated at €320,664, and the incremental cost per decayed, missing, or filled tooth (d3vcmft/D3vcMFT) prevented was calculated at €14.09. The potential annual lifetime treatment savings associated with caries prevented for this cohort was estimated at €2.95 million. When the potential treatment savings were included in the analysis, the incremental cost per d3vcmft/D3vcMFT prevented was -€115.67, representing a cost-saving to the health-payer and a positive return on investment. The results of the analysis were robust to both deterministic and probability sensitivity analyses.ConclusionDespite current access to numerous fluoride sources and a reported increase in the prevalence of enamel fluorosis, CWF remains a cost-effective public health intervention for Irish schoolchildren.

App-Based Salt Reduction Intervention in School Children and Their Families (AppSalt) in China: Protocol for a Mixed Methods Process Evaluation

BackgroundThe app-based salt reduction intervention program in school children and their families (AppSalt) is a multicomponent mobile health (mHealth) intervention program, which involves multiple stakeholders, including students, parents, teachers, school heads, and local health and education authorities. The complexity of the AppSalt program highlights the need for process evaluation to investigate how the implementation will be achieved at different sites.ObjectiveThis paper presents a process evaluation protocol of the AppSalt program, which aims to monitor the implementation of the program, explain its causal mechanisms, and provide evidence for scaling up the program nationwide.MethodsA mixed methods approach will be used to collect data relating to five process evaluation dimensions: fidelity, dose delivered, dose received, reach, and context. Quantitative data, including app use logs, activity logs, and routine monitoring data, will be collected alongside the intervention process to evaluate the quantity and quality of intervention activities. The quantitative data will be summarized as medians, means, and proportions as appropriate. Qualitative data will be collected through semistructured interviews of purposely selected intervention participants and key stakeholders from local health and education authorities. The thematic analysis technique will be used for analyzing the qualitative data with the support of NVivo 12. The qualitative data will be triangulated with the quantitative data during the interpretation phase to explain the 5 process evaluation dimensions.ResultsThe intervention activities of the AppSalt program were initiated at 27 primary schools in three cities since October 2018. We have completed the 1-year intervention of this program. The quantitative data for this study, including app use log, activity logs, and the routine monitoring data, were collected and organized during the intervention process. After completing the intervention, we conducted semistructured interviews with 32 students, 32 parents, 9 teachers, 9 school heads, and 8 stakeholders from local health and education departments. Data analysis is currently underway.ConclusionsUsing mHealth technology for salt reduction among primary school students is an innovation in China. The findings of this study will help researchers understand the implementation of the AppSalt program and similar mHealth interventions in real-world settings. Furthermore, this process evaluation will be informative for other researchers and policy makers interested in replicating the AppSalt program and designing their salt reduction intervention.International Registered Report Identifier (IRRID)DERR1-10.2196/19430

Sustainability of Healthy Nutritional Policy Interventions for School Children: A Case Study of Mid-Day Meal Scheme in Odisha, India

Sustainability of Healthy Nutritional Policy Interventions for School Children: A Case Study of Mid-Day Meal Scheme in Odisha, India

Does Design Thinking Training Really Increase Creativity? Results from an Experiment with Middle-School Students

Design thinking remains mired in controversy. Its proponents claim that it enhances not just confidence but also creativity, but its opponents question whether it does anything beyond building unfounded confidence. In order to bring rigorous evidence to this debate, we designed a randomized experiment amongst school children served by a major non-governmental organization in rural India. A well-established design thinking intervention for school children comprised the treatment, and the organization’s existing science-based intervention for hands-on learning served as the control condition. The findings reveal that the design thinking training did not just increase confidence: it also significantly increased ideational fluency and elaboration in a divergent thinking task, although the originality and flexibility of the generated ideas was on average lower in the treatment group than the control group. The intervention had no effect on perspective taking or risk aversion. We also find that the increase in confidence occurred primarily among female students, whereas the increase in ideational fluency and elaboration occurred for both genders.

The longitudinal relationship between motor competence and measures of fatness and fitness from childhood into adolescence

ObjectivesTo examine longitudinal (seven years) relationships among cardiorespiratory fitness (VO2peak), body fatness, and motor competence. MethodData were collected as part of the Copenhagen School Child Intervention Study (CoSCIS). Body fatness was assessed by the sum of four skinfolds. VO2peak was measured directly in a continuous running protocol. Motor competence was assessed using the Körperkoordinationtest für Kinder. This study used multilevel linear mixed models to evaluate the reciprocal longitudinal association between body fatness, VO2peak, and motor competence. All regressions were stratified by sex and adjusted by intervention and pubertal status. All variable coefficients were standardized. ResultsA reciprocal relationship was observed between children's motor competence with body fatness and VO2peak at the seven‐year follow‐up (6–13 years of age). Children with higher motor competence at baseline had a lower risk of having higher body fatness (βboys=−0.45, 95% CI: −0.52 to −0.38; βgirls=−0.35, 95% CI: −0.42 to −0.28) and higher VO2peak (βboys=0.34, 95% CI: 0.27–0.40; βgirls=0.27, 95% CI: 0.20–0.33) during childhood. Alternatively, higher body fatness or lower levels of VO2peak at baseline were associated with lower motor competence during childhood. ConclusionsThese data suggest motor competence, body fatness, and VO2peak demonstrate reciprocal relationships across childhood (6–13 years of age). Interventions addressing motor competence, cardiorespiratory fitness, and body fatness in early childhood are recommended, as intervention effects are likely to be enhanced because of the mutual reciprocal associations between these three variables.

Saliva collection and detection of anti- T. gondii antibodies of low-income school-age children as a learning strategy on hygiene, prevention and transmission of toxoplasmosis.

ABSTRACTSchool-age children are a social group in which blood collection for laboratory testing can be perceived as an invasive procedure, with low acceptance and tolerance of stakeholders. This problem could be circumvented by replacing serum samples with saliva. For this purpose, and to make the collection of saliva samples playful and instructive for children, educational activities on hygiene and toxoplasmosis transmission and prevention were performed using toys and audiovisual tools. The target audience consisted of 7-10 year-old children from low-income families who attended public schools in the city of São Paulo. Saliva samples were used in a previously described in-house Enzyme-Linked Immunosorbent Assays (ELISA) to detect anti- Toxoplasma gondii IgG antibodies and establish the immunological status of each of the participants. One year later, children’s memory and fixation of concepts regarding hygiene habits, as well as transmission and prevention of toxoplasmosis were tested in the same schools, by means of a questionnaire application, using students who did not participate in the first intervention as controls. The prevalence of positive anti- T. gondii IgG among students was 50% (82/164). One year later, 45 children had more knowledge on toxoplasmosis (28/45 vs 29/147) and they drew the cat’s involvement in the transmission of toxoplasmosis more often than controls (28/45 vs 29/147). Sorted according to the presence of specific IgG in saliva, recovered positive students presented worse memory of the above cited knowledge as did saliva-negative IgG students, but both groups had isolated higher frequency of fixed knowledge than non-intervened students. Our data show that there is a high prevalence of T. gondii infection in school-children from low-income areas; saliva is an alternative to blood for anti- T. gondii IgG detection; and a one-day educational intervention in school-children was effective in promoting knowledge fixation on hygiene and toxoplasmosis transmission and prevention after one year.

Design and implementation of a health promotion program to prevent the harmful effects of ultraviolet radiation at primary school students of rural areas of Greece

&lt;p class="abstract"&gt;&lt;strong&gt;Background:&lt;/strong&gt; &lt;span lang="EN-IN"&gt;Skin cancer is the most common type of cancer presenting with a dramatic increase in its incidence among Caucasian populations worldwide. Primary prevention in childhood and early detection is important in reducing the risk of skin cancer later in life.&lt;/span&gt;The o&lt;span lang="EN-IN"&gt;bjectives of the study were to investigate the effect of a focused educational intervention in school children aiming to increase their knowledge about the harmful effects of sun exposure and promote prevention behaviors regarding skin cancer&lt;/span&gt;&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Methods:&lt;/strong&gt; &lt;span lang="EN-IN"&gt;The study consisted of a before/after 6-month assessment of a school intervention program applied in two hundred children from four primary Schools (Grades 3-6) at a rural area in Western Greece. The program included the presentation and distribution of educational material (activity guide, manual for pupils, posters). A detailed questionnaire with close-ended questions was distributed before and after the intervention. Both between and in groups analysis was conducted&lt;/span&gt;.&lt;strong&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Results:&lt;/strong&gt; &lt;span lang="EN-IN"&gt;Of the participating pupils, 48% were boys, whereas 78.5% reported a fair skin complexion and 79% reported freckles and 1-20 nevi. After the intervention, an increased number of pupils were taught to enjoy sun exposure while avoiding its harmful effects. A significantly greater number of children stated proper use of sunscreen (74% vs. 31%, p=0.001) and sun protection (that avoided going outside especially at the intense hours of daily UV exposure (65% vs. 25.5% prior to the intervention). Melanoma awareness was also significantly raised. &lt;/span&gt;&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Conclusions:&lt;/strong&gt; &lt;span lang="EN-IN"&gt;Students’ knowledge about the effects of sun exposure as well as the need for sun protection increased following a targeted and well-designed educational intervention. The development of preventive educational programs on skin cancer for school children is important to increase awareness in this sensitive age group.&lt;/span&gt;&lt;/p&gt;
