Abstract
Background: Community-based interventions hold promise for addressing adolescent malnutrition, but there is limited knowledge of their nature and impact on adolescent nutrition outcomes in low- and middle-income countries (LMICs). This scoping review aimed to characterize community-based adolescent nutrition interventions in LMICs and summarize their effects on adolescent nutrition outcomes.
Methods: We systematically searched MEDLINE via PubMed, Embase, and CENTRAL through the Cochrane Library for studies published between 2000 and 2023. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines. Eligible studies included randomized controlled trials and quasi-experimental studies addressing adolescent malnutrition in LMIC community settings, involving adolescents aged 10-19 years. A narrative synthesis was employed to analyze and describe the evidence.
Results: Our review included 37 records from 36 studies conducted in 27 countries. Interventions included micronutrient supplementation, nutrition education, food supplementation and fortification, physical activity education, and multicomponent approaches. The intervention duration ranged from 3 weeks to 2 years, with limited studies grounded in theoretical frameworks. Fifty-seven percent of interventions (n = 21) targeted adolescent girls, indicating a gap in programs for boys and other vulnerable groups, such as out-of-school adolescents and migrants. The intervention delivery agents included research staff and healthcare professionals. The majority of interventions were delivered in person; few utilized social media strategies. Among the studies reviewed, nine out of ten evaluating micronutrient supplementation, six out of seven assessing nutrition education, and seven out of eight examining multicomponent interventions reported improvement in at least one nutrition or diet-related outcome.
Conclusions: Community-based interventions hold promise for improving adolescent nutritional status in LMICs. However, our review highlights gaps in the evidence base, marked by significant variability in intervention design, delivery, and implementation platforms. This underscores the need for integrated approaches and rigorous evaluations of their implementation outcomes, including acceptability, relevance, feasibility, effectiveness, and sustainability, in addressing adolescent nutrition challenges.
Registration: The review protocol was registered prospectively with the Open Science Framework on 19 July 2023 ( https://osf.io/t2d78 ).
期刊介绍：
Nutrition Journal publishes surveillance, epidemiologic, and intervention research that sheds light on i) influences (e.g., familial, environmental) on eating patterns; ii) associations between eating patterns and health, and iii) strategies to improve eating patterns among populations. The journal also welcomes manuscripts reporting on the psychometric properties (e.g., validity, reliability) and feasibility of methods (e.g., for assessing dietary intake) for human nutrition research. In addition, study protocols for controlled trials and cohort studies, with an emphasis on methods for assessing dietary exposures and outcomes as well as intervention components, will be considered.
Manuscripts that consider eating patterns holistically, as opposed to solely reductionist approaches that focus on specific dietary components in isolation, are encouraged. Also encouraged are papers that take a holistic or systems perspective in attempting to understand possible compensatory and differential effects of nutrition interventions. The journal does not consider animal studies.
In addition to the influence of eating patterns for human health, we also invite research providing insights into the environmental sustainability of dietary practices. Again, a holistic perspective is encouraged, for example, through the consideration of how eating patterns might maximize both human and planetary health.
