Social isolation is recognised as a risk factor in the inflammatory process. This study explored the association between social isolation and the Dietary Inflammatory Index (DII) in community-dwelling older persons.
This cross-sectional pilot study recruited 107 community-dwelling people aged over 55 years living in the Australian Capital Territory. Participants completed an extensive food frequency questionnaire and provided anthropometric and sociodemographic data. Social isolation was evaluated using the Lubben Social Network Scale (LSNS). Diet quality was assessed using DII.
Average age was 70.1 (±8.61) years and 62.8% were female. The average DII score was -1.10 (±1.21), indicating an anti-inflammatory diet. Higher LSNS was associated with lower DII (b (95% CI) = -0.041 (-0.066, -0.17); < 0.01) and was positively influenced by the number of people in household (b (95% CI) = 5.731 (2.336, 9.127); = 0.001).
Increased risk of social isolation was associated with an increased tendency towards a more inflammatory diet. Reducing social isolation may decrease the inflammatory component of dietary intake for older persons living independently in the community.
社会隔离被认为是炎症过程中的一个风险因素。本研究探讨了社区居住老年人中社会隔离与饮食炎症指数（DII）之间的关联。
这项横断面试点研究招募了107名居住在澳大利亚首都地区、年龄超过55岁的社区居民。参与者完成了一份详尽的食物频率问卷，并提供了人体测量和社会人口学数据。使用鲁本社会网络量表（LSNS）评估社会隔离情况。使用DII评估饮食质量。
平均年龄为70.1（±8.61）岁，女性占62.8%。DII平均得分为-1.10（±1.21），表明是抗炎饮食。较高的LSNS与较低的DII相关（b（95%CI）=-0.041（-0.066，-0.17）；P<0.01），并且受家庭人口数量的正向影响（b（95%CI）=5.731（2.336，9.127）；P=0.001）。
社会隔离风险增加与饮食炎症倾向增加有关。减少社会隔离可能会降低社区中独立生活的老年人饮食摄入的炎症成分。
