BACKGROUND/OBJECTIVES: The study's objective was to determine whether social isolation serves as a mediator in the cross-sectional relationship between food insecurity, both as a short-term and longer-term situation, with resource use and depressive symptoms as outcomes.
This cross-sectional design study utilized secondary survey data, including 30-day and 12-month food security measured by the U.S. Household Food Security Survey Module. The Baron-Kenny mediation approach was used to determine whether social isolation mediated the relationship between food security, depressive symptoms, and resource use ( ≤ 0.05).
Social isolation mediates the association between both 30-day and 12-month food security with depressive symptoms but not resource use.
Acknowledging and targeting social isolation, policies, and interventions that integrate peer support and community outreach to promote food security could support rural veterans food security and mental health.
背景/目的：本研究的目的是确定社会孤立是否在粮食不安全（包括短期和长期情况）与以资源使用和抑郁症状为结果的横断面关系中起中介作用。
这项横断面设计研究利用了二次调查数据，包括通过美国家庭粮食安全调查模块测量的30天和12个月的粮食安全情况。采用Baron-Kenny中介方法来确定社会孤立是否介导了粮食安全、抑郁症状和资源使用之间的关系（≤0.05）。
社会孤立介导了30天和12个月粮食安全与抑郁症状之间的关联，但未介导与资源使用的关联。
认识到社会孤立并将其作为目标，整合同伴支持和社区外展以促进粮食安全的政策和干预措施可以支持农村退伍军人的粮食安全和心理健康。
