Early malnutrition and/or micronutrient deficiencies can negatively affect many aspects of child health and development. School feeding programs are designed to provide food to hungry children and to improve their physical, mental and psychosocial health. This is the first systematic review on the topic of school feeding. Eighteen studies were included in this review; nine were performed in higher income countries and nine in lower income countries. In the highest quality studies (randomized controlled trials (RCTs) from low income countries, children who were fed at school gained an average of 0.39 kg more than controls over 19 months; in lower quality studies (controlled before and after trials (CBAs)), the difference in gain was 0.71 kg over 11.3 months. Children who were fed at school attended school more frequently than those in control groups; this finding translated to an average increase of 4 to 6 days a year per child. For educational and cognitive outcomes, children who were fed at school gained more than controls on math achievement, and on some short-term cognitive tasks.Results from higher income countries were mixed, but generally positive. For height, results from lower income countries were mixed; in RCTs, differences in gains were important only for younger children, but results from the CBAs were large and significant overall. Results for height from high Income countries were mixed, but generally positive. School meals may have small physical and psychosocial benefits for disadvantaged pupils. We recommend that further well-designed studies on the effectiveness of school meals be undertaken, that results should be reported according to the socio-economic status of the children who take part in them, and that researchers gather robust data on outcomes that directly reflect effects on physical, social, and psychological health.

    • "The scale-up has often been accompanied with the mainstreaming of school feeding within national education sector policies and plans. The programme theory on the educational effects of school feeding is generally well established and underpinned by an increasingly robust evidence base (see Alderman and Bundy, 2011; Kristjansson et al., 2007; Adelman et al., 2008, for recent reviews). School feeding programmes can support enrolment and attendance; and once children are in school, the programmes can contribute to their learning, through avoiding short-term hunger, enhancing attention and cognition, though the evidence on the latter point is mixed.

    ABSTRACT: This cross-sectional study examines the status and the determinants of primary education in food insecure areas of Mali. Net and gross enrolment ratios in primary school were between 0.3 and 0.4 for both girls and boys and well below national levels, highlighting a critical gap in terms of access to primary education. Schooling was found to respond to a broad range of determinants, including child's age and nutrition status, as well as on household consumption, on farm labour, teacher availability, and village level remoteness. Interestingly, no significant gender differences were found in terms of primary education. School meals were found to be associated with increased enrolment, attendance and attainment. The scale of the problem in Mali strongly suggests the need for investments in education and social protection to be prioritised and funded as part of national education policy and development strategies.

    • "At the time we conducted this synthesis, (2009–2011), few examples of realist reviews had been published. Most examples looked at sets of similar or related interventions working on similar program goals to better understand the causes of their successes and challenges (Kristjansson et al., 2007; Wong et al., 2010). Similar to our review, these reviews handled significant complexity and heterogeneity in their respective research areas. "

    ABSTRACT: Realist review has increased in popularity as a methodology for complex intervention assessment. Our experience suggests that the process of designing a realist review requires its customization to areas under investigation. To elaborate on this idea, we first describe the logic underpinning realist review and then present critical reflections on our application experience, organized in seven areas. These are the following: (1) the challenge of identifying middle range theory; (2) addressing heterogeneity and lack of conceptual clarity; (3) the challenge of appraising the quality of complex evidence; (4) the relevance of capturing unintended outcomes; (5) understanding the process of context, mechanism, and outcome (CMO) configuring; (6) incorporating middle-range theory in the CMO configuration process; and (7) using middle range theory to advance the conceptualization of outcomes - both visible and seemingly 'hidden'. One conclusion from our experience is that the degree of heterogeneity of the evidence base will determine whether theory can drive the development of review protocols from the outset, or will follow only after an intense period of data immersion. We hope that presenting a critical reflection on customizing realist review will convey how the methodology can be tailored to the often complex and idiosyncratic features of health research, leading to innovative evidence syntheses.

    • "This would also lessen the risk of increasing stigmatization. Regarding poverty, research has demonstrated improvements in child educational outcomes as a result of school feeding schemes , social grants, and other poverty-alleviation measures (Kristjansson et al., 2007). Regarding the psycho-social consequences, for instance addressing internalising problems to improve Pathways to poor educational outcomes for HIV/AIDS-affected youth 12 classroom concentration, the literature is more limited, though there are indications of the benefits of support groups (Kumakech, Cantor-Graae, & Maling, 2009), and indeed of measures to diminish poverty (Cluver & Orkin, 2009).

    ABSTRACT: A recent systematic review of studies in the developing world has critically examined linkages from familial HIV/AIDS and associated factors such as poverty and child mental health to negative child educational outcomes. In line with several recommendations in the review, the current study modelled relationships between familial HIV/AIDS, poverty, child internalising problems, gender and four educational outcomes: non-enrolment at school, non-attendance, deficits in grade progression and concentration problems. Path analyses reveal no direct associations between familial HIV/AIDS and any of the educational outcomes. Instead, HIV/AIDS-orphanhood or caregiver HIV/AIDS-sickness impacted indirectly on educational outcomes via the poverty and internalising problems that they occasioned. This has implications for evidence-based policy inferences. For instance, by addressing such intervening variables generally, rather than by seeking to target families affected by HIV/AIDS, interventions could avoid exacerbating stigmatisation, while having a more direct and stronger impact on children's educational outcomes. This analytic approach also suggests that future research should seek to identify causal paths, and may include other intervening variables related to poverty (such as child housework and caring responsibilities) or to child mental health (such as stigma and abuse), that are linked to both familial HIV/AIDS and educational outcomes.
