Comprehensive school-based health programs to improve child and adolescent health: Evidence from Zambia.

ABSTRACT: BACKGROUND:While school-aged children in low- and middle-income countries remain highly exposed to acute infections, programs targeting this age group remain limited in scale and scope. In this paper, we evaluate the impact of a new and comprehensive primary school-based health intervention program on student-reported morbidity and anthropometric outcomes in Lusaka, Zambia. METHODS:A prospective matched control study identified 12 classes in 7 schools for the intervention and 12 classes in 7 matched schools as controls. Teachers in intervention schools were trained to deliver health lessons and to refer sick students to care. In addition, vitamin A and deworming medication were biannually administered to intervention students. The primary study outcome was student-reported morbidity. Secondary outcomes were weight, height, health knowledge, and absenteeism. Multivariable linear and logistic regression models were used to estimate program impact. RESULTS:380 students ages 4-16 were enrolled in the study in 2015, and 97% were followed up at endline in 2016. The intervention decreased the adjusted odds of self-reported acute illnesses by 38% (95% CI: 0.48, 0.77) and the adjusted odds of stunting by 52% (95% CI: 0.26, 0.87). It also increased health knowledge by 0.53 standard deviations (95% CI: 0.24, 0.81). No impact was found on weight (adjusted mean difference ? = 0.17, 95% CI: - 1.11, 1.44) and student absenteeism (adjusted odds ratio (aOR) = 0.89, 95% CI: 0.60, 1.33). CONCLUSION:The results presented in this paper suggest that comprehensive school-based health programs may offer a highly effective way to improve students' health knowledge as well as their health status. Given their low cost, a more general adoption and implementation of such programs seems recommendable. TRIAL REGISTRATION:ClinicalTrials.gov Identifier: NCT03607084.

Project description:BackgroundGlobally, 19 million children have preventable vision impairment simply because refractive and eye health services are inaccessible to most of them. In Zambia, approximately 50,000 school children need spectacle provision. The School-based Eye Health Programme (SEHP) has been identified worldwide as a proven strategy to address childhood blindness. Given its great benefits, the Zambian government intends to scale up the programme. This scalability assessment aims to identify and evaluate the essential components of an effective SEHP, determine roles, assess existing capacities within user organisations, identify environmental facilitating and inhibiting factors, and estimate the minimum resources necessary for the scaling up and their proposed scale-up strategies.MethodsFive elements (innovation, user organisation, resource team, environment, and strategies for horizontal and vertical scaling-up) were assessed guided by the ExpandNet-WHO Nine Steps for Developing a Scaling-Up Strategy. Literature review on proven strategies to reduce childhood blindness and the credibility of SEHP implemented in resource-limited settings, document review on the pilot project, questionnaires, and stakeholders' interviews were conducted to collect data for this assessment. Subsequently, twenty questions in the Worksheets for Developing a Scaling-up Strategy were used to report the assessment outcome systematically.ResultsAdditional components of SEHP incorporated in Zambia's model enhanced the innovation's credibility and relevance. The resource team was relatively competent in the pilot project, and the same team will be employed during the scaling-up. Potential change in political parties, the lack of supply chain, and unstable financial support were identified as inhibiting factors. The objectives of SEHP were aligned with the National Eye Health Strategic Plan 2017-2021, which supports the institutionalisation of the SEHP into the existing School Health and Nutrition Programme. For the pace of expansion, replicating SEHP to another district rather than a province will be more realistic.ConclusionScaling up a comprehensive SEHP in Zambia is feasible if sufficient funding is available. Additionally, the pace must be adapted to the local context to ensure that every component within the SEHP is intact.

Project description:Background: Existing efforts to understand school-based child sexual abuse (CSA) prevention programs mainly focus on the effectiveness of these programs in increasing participants' CSA knowledge and self-protective skills. There are currently no reviews addressing the underpinning pathways leading to these outcomes. In order to increase our understanding about the underpinning causal and contextual factors and inform the further development of school-based CSA prevention programs, a realist review was conducted to synthesize existing evidence from a broad range of data. Methods: An iterative search of electronic databases and grey literature was conducted, supplemented with citation tracking to locate relevant literature. For quantitative evidence, we considered evaluation studies that focused on students aged 5-18 years, who were enrolled in primary or secondary schools; for other types/formats of studies/documents, no population restrictions were applied. We included school-based CSA prevention programs that focused on improving knowledge of CSA or self-protective skills. Outcomes of interest included knowledge of CSA or self-protective skills. We did not apply methodological filters in terms of the types of studies to be included. Thematic content analysis was conducted to synthesize data. Results: Sixty-two studies were included. Five themes and five overarching Context-Strategy-Mechanism-Outcome configurations (CSMOs) that contributed to the success of school-based CSA interventions were identified, including tailoring programs to participants' cognitive developmental levels, repeated exposure of key concepts and skills, utilization of interactive delivery methods and positive feedback, delivery of positive information and application of the 'train-the-trainer' model. Implications: Findings from this realist review provide insights into the underlying program theory of school-based CSA prevention programs, which can aid in the development and implementation of these programs in the future.

Project description:The relationship between child development and adolescent health, and how this may be modified by socio-economic conditions, is poorly understood. This limits cross-sector interventions to address adolescent health inequality. This review summarises evidence on the associations between child development at school starting age and subsequent health in adolescence and identifies factors affecting associations. We undertook a participatory systematic review, searching electronic databases (MEDLINE, PsycINFO, ASSIA and ERIC) for articles published between November 1990 and November 2020. Observational, intervention and review studies reporting a measure of child development and subsequent health outcomes, specifically weight and mental health, were included. Studies were individually and collectively assessed for quality using a comparative rating system of stronger, weaker, inconsistent or limited evidence. Associations between child development and adolescent health outcomes were assessed and reported by four domains of child development (socio-emotional, cognitive, language and communication, and physical development). A conceptual diagram, produced with stakeholders at the outset of the study, acted as a framework for narrative synthesis of factors that modify or mediate associations. Thirty-four studies were included. Analysis indicated stronger evidence of associations between measures of socio-emotional development and subsequent mental health and weight outcomes; in particular, positive associations between early externalising behaviours and later internalising and externalising, and negative associations between emotional wellbeing and later internalising and unhealthy weight. For all other domains of child development, although associations with subsequent health were positive, the evidence was either weaker, inconsistent or limited. There was limited evidence on factors that altered associations. Positive socio-emotional development at school starting age appears particularly important for subsequent mental health and weight in adolescence. More collaborative research across health and education is needed on other domains of development and on the mechanisms that link development and later health, and on how any relationship is modified by socio-economic context.

Project description:BackgroundThis paper assesses the effectiveness of community-based primary health care (CBPHC) in improving child health beyond the neonatal period. Although there has been an accelerated decline in global under-5 mortality since 2000, mortality rates remain high in much of sub-Saharan Africa and in some south Asian countries where under-5 mortality is also decreasing more slowly. Essential interventions for child health at the community level have been identified. Our review aims to contribute further to this knowledge by examining how strong the evidence is and exploring in greater detail what specific interventions and implementation strategies appear to be effective.MethodsWe reviewed relevant documents from 1950 onwards using a detailed protocol. Peer reviewed documents, reports and books assessing the impact of one or more CBPHC interventions on child health (defined as changes in population coverage of one or more key child survival interventions, nutritional status, serious morbidity or mortality) among children in a geographically defined population was examined for inclusion. Two separate reviews took place of each document followed by an independent consolidated summative review. Data from the latter review were transferred to electronic database for analysis.ResultsThe findings provide strong evidence that the major causes of child mortality in resource-constrained settings can be addressed at the community level largely by engaging communities and supporting community-level workers. For all major categories of interventions (nutritional interventions; control of pneumonia, diarrheal disease and malaria; HIV prevention and treatment; immunizations; integrated management of childhood diseases; and comprehensive primary health care) we have presented randomized controlled trials that have consistently produced statistically significant and operationally important effects.ConclusionsThis review shows that there is strong evidence of effectiveness for CBPHC implementation of an extensive range of interventions to improve child health and that four major strategies for delivering these interventions are effective.

Project description:School-based programs seem promising for child abuse prevention. However, research mainly focused on sexual child abuse and knowledge is lacking on how individual program components contribute to the effectiveness of school-based prevention programs for any form of child abuse. This study aimed to examine the overall effect of these school-based programs on (a) children's child abuse-related knowledge and (b) self-protection skills by conducting two three-level meta-analyses. Furthermore, moderator analyses were performed to identify how program components and delivery techniques were associated with effectiveness. A literature search yielded 34 studies (158 effect sizes; N = 11,798) examining knowledge of child abuse and 22 studies (99 effect sizes; N = 7804) examining self-protection skills. A significant overall effect was found of school-based programs on both knowledge (d = 0.572, 95% CI [0.408, 0.737], p < 0.001) and self-protection skills (d = 0.528, 95% CI [0.262, 0.794], p < 0.001). The results of the first meta-analysis on children's child abuse knowledge suggest that program effects were larger in programs addressing social-emotional skills of children (d = 0.909 for programs with this component versus d = 0.489 for programs without this component) and self-blame (d = 0.776 versus d = 0.412), and when puppets (d = 1.096 versus d = 0.500) and games or quizzes (d = 0.966 versus d = 0.494) were used. The second meta-analysis on children's self-protections skills revealed that no individual components or techniques were associated with increased effectiveness. Several other study and program characteristics did moderate the overall effects and are discussed. In general, school-based prevention programs show positive effects on both knowledge and self-protection skills, and the results imply that program effectiveness can be improved by implementing specific components and techniques.

Project description:BackgroundAdolescent pregnancy is a global public health problem. Numerous approaches for Comprehensive Sexuality Education (CSE) delivery in schools have been implemented around the world. Previous reviews on CSE did not follow the International Technical Guidance on Sexuality Education (ITGSE) because CSE is very diverse in terms of population, interventions, settings and outcomes. We conducted this scoping review to identify and map the evidence of school-based CSE for prevention of adolescent pregnancy with emphasis on adolescents' contraceptive use, unintended pregnancy and abortion.MethodsWe searched PubMed, CENTRAL, Scopus, ISI Web of Science, CINAHL, and WHO ICTRP to identify potential eligible studies from their inception to 4th Nov 2023.We included randomized controlled trials (RCTs) and non-RCTs of CSE implemented in public or private schools for adolescents. CSE was defined as a multi-session intervention in school that covered topics including contraception, pregnancy, abortion, and HIV/STI. School-based interventions were the main intervention that may be either stand-alone or multicomponent. There was no limitation on study's geographical area, but only English-language studies were considered. Two reviewers selected and extracted data independently, discussed for consensus or consulted the third reviewer if there were discrepancies for final conclusion. Data were presented using figures, map and table.ResultsOut of 5897 records, 79 studies (101 reports) were included in this review. Most studies were conducted in the United States and other high-income countries in secondary or high schools with cluster RCTs. All studies included participatory methods. Almost all studies included Sexual and Reproductive Health which is the eighth concept of CSE. Very few studies reported the prespecified primary outcomes of contraceptive use during last sex, unintended pregnancy and abortion and hence this highlighted the gaps of available evidence for these outcomes. The number of concepts, components, duration and providers of CSE varied across the included studies. However, none of the interventions identified in this scoping review adhered to the ITGSE recommended approach.ConclusionsOur scoping review shows gaps in school-based CSE implementation in terms of completeness of concepts, components, providers, duration and outcomes recommended by ITGSE.
