(c) the authors, CC-BY 4.0 Supplementary files for article Designing intervention prototypes to improve infant and young child nutrition in Peru: A participatory design study protocol<b>Introduction:</b> Nutrition during the complementary feeding period (6-23 months) is critical to ensure optimal growth and reduce the risk of diet-related disease across the life course. Strategies to reduce multiple forms of malnutrition (stunting, overweight/obesity and anaemia) in infants and young children (IYC) are a key priority in low- and middle-income countries, including Peru. This study aims to co-design and develop prototypes for interventions to address the multiple forms of malnutrition in IYC in urban Peru, using a participatory design approach.<b>Methods and analysis</b>: The study will be based within peri-urban communities in two areas of Peru (Lima and Huánuco city). Following the identification of key nutritional challenges for IYC aged 6-23 months through formative research (Phase 1), we will conduct a series of workshops bringing together healthcare professionals from government health centres and caregivers of IYC aged 6-23 months. Workshops (on idea generation; creating future scenarios; storyboarding, and early implementation and feedback) will take place in parallel in the two study areas. Through these workshops, we will engage with community participants to explore, experiment, co-design, and iteratively validate new design ideas to address the challenges around IYC complementary feeding from Phase 1. Workshop outputs and transcripts will be analysed qualitatively using affinity diagramming and thematic analyses. The intervention prototypes will be evaluated qualitatively and piloted with the participating communities.<b>Ethics and dissemination:</b> Ethical approval for this study was obtained from the Ethical Review Committee of the Instituto de Investigación Nutricional (IIN) Peru (388-2019/CIEIIIN), Loughborough University (C19-87) and confirmed by Cardiff University. Findings of the participatory design process will be disseminated through a deliberative workshop in Lima, Peru with national and regional government stakeholders, as well as participants and researchers involved in the design process. Further dissemination will take place through policy briefs, conferences and academic publications.

**引言**：辅食添加期（6~23月龄）的营养摄入对保障婴幼儿最优生长发育、降低终生膳食相关疾病风险至关重要。降低婴幼儿（Infants and Young Children, IYC）多种形式营养不良（生长迟缓、超重/肥胖及贫血）的策略，是包括秘鲁在内的中低收入国家的核心工作重点。本研究旨在采用参与式设计方法，协同设计并开发针对秘鲁城市地区婴幼儿多重营养不良问题的干预原型。

**方法与分析**：本研究将在秘鲁两个区域的城郊社区开展（利马市与瓦努科市）。首先通过形成性研究（第一阶段）明确6~23月龄婴幼儿的核心营养挑战，随后举办多场研讨会，召集公立医疗中心的医护人员与6~23月龄婴幼儿的照护者共同参与。研讨会涵盖创意生成、未来场景构建、故事板创作以及早期实施与反馈四个环节，将在两个研究区域同步推进。通过上述研讨活动，我们将邀请社区参与者共同探索、实践、协同设计并迭代验证新的设计方案，以解决第一阶段明确的婴幼儿辅食喂养相关挑战。研讨会产出物及会议转录文本将采用亲和图法与主题分析法开展质性分析。干预原型将通过质性评估，并在参与社区中进行试点测试。

**伦理与成果传播**：本研究已获得秘鲁营养研究所（Instituto de Investigación Nutricional, IIN）伦理审查委员会批准（审批号：388-2019/CIEIIIN）、拉夫堡大学伦理审查批准（审批号：C19-87），并经卡迪夫大学确认。参与式设计过程的研究成果将通过在秘鲁利马举办的研讨会议，向国家及地方政府利益相关方、研究参与者与本研究团队进行传播。后续还将通过政策简报、学术会议及学术出版物进一步推广研究成果。
