To establish an international consensus on the definition of food security, measures and advocacy priorities in high-income countries.
A two-round online Delphi survey with closing in March 2020 and December 2021. Consensus was set a priori at 75 %. Qualitative data were synthesised and priorities were ranked.
High-income countries.
Household food security experts in academia, government and non-government organisations who had published in the last 5 years.
Up to thirty-two participants from fourteen high-income countries responded to the Delphi with a 25 % response rate in Round 1 and a 38 % response rate in Round 2. Consensus was reached on the technical food security definition and its dimensions. Consensus was not reached on a definition suitable for the general public. All participants agreed that food security monitoring systems provide valuable data for in-country decision-making. Favoured interventions were those that focused on upstream social policy influencing income. Respondents agreed that both national and local community level strategies were required to ameliorate food insecurity, reinforcing the complexity of the problem.
This study furthers the conceptual understanding of the commonly used definition of food security and its constituent dimensions. Strong advocacy is needed to ensure food security monitoring, policy and mitigation strategies are implemented. The consensus on the importance of prioritising actions that address the underlying determinants of household food security by experts in the field from across wealthy nations provides evidence to focus advocacy efforts and generate public debate.
就高收入国家的食品安全定义、措施和宣传重点达成国际共识。
两轮在线德尔菲调查，分别于 2020 年 3 月和 2021 年 12 月结束。事先设定的共识标准为 75%。对定性数据进行综合分析，并对重点进行排名。
高收入国家。
在学术界、政府和非政府组织中从事家庭食品安全工作并在过去 5 年内发表过文章的专家。
共有来自 14 个高收入国家的 32 名参与者对德尔菲进行了回复，第一轮的回复率为 25%，第二轮为 38%。就技术食品安全定义及其维度达成共识。对于适合公众的定义未达成共识。所有参与者都同意食品安全监测系统为国内决策提供了有价值的数据。优先考虑的干预措施是那些专注于影响收入的上游社会政策。受访者一致认为，需要国家和地方社区层面的战略来缓解粮食不安全问题，这突显了问题的复杂性。
本研究深化了对常用食品安全定义及其构成维度的概念理解。需要大力宣传，以确保实施食品安全监测、政策和缓解战略。该研究结果表明，来自富裕国家的该领域专家一致认为，优先采取行动解决家庭食品安全的根本决定因素非常重要，这为集中宣传工作和引发公众讨论提供了证据。
