To synthesise the research which has sought to evaluate interventions aiming to tackle children's food insecurity and the contribution of this research to evidencing the effectiveness of such interventions.
The majority of studies in this review were quantitative, non-randomised studies, including cohort studies. Issues with non-complete outcome data, measurement of duration of participation in interventions, and accounting for confounds are common in these evaluation studies. Despite the limitations of the current evidence base, the papers that were reviewed provide evidence for multiple positive outcomes for children participating in attended and subsidy interventions, inter alia, reductions in food insecurity, poor health and obesity. However, current evaluations may overlook key areas of impact of these interventions on the lives and outcomes of participating children. This review suggests that the current evidence base which evaluates food insecurity interventions for children is both mixed and limited in scope and quality. In particular, the outcomes measured are narrow, and many papers have methodological limitations. With this in mind, a systems-based approach to both implementation and evaluation of food poverty interventions is recommended.
综合旨在解决儿童粮食不安全问题的干预措施的研究,并评估这些研究对证明此类干预措施有效性的贡献。
本综述中的大多数研究都是定量的、非随机研究,包括队列研究。在这些评估研究中,存在非完整结局数据、干预参与时间的测量以及对混杂因素的考虑等问题。尽管当前证据基础存在局限性,但综述中所审查的论文为参加参与式和补贴式干预的儿童提供了多个积极结果的证据,例如,粮食不安全、健康状况不佳和肥胖的减少。然而,当前的评估可能忽略了这些干预措施对参与儿童生活和结果的关键影响领域。本综述表明,目前评估儿童粮食不安全干预措施的证据基础既有局限性,也有局限性。特别是,所测量的结果很狭窄,许多论文都存在方法学上的局限性。有鉴于此,建议采用基于系统的方法来实施和评估粮食贫困干预措施。
