The dietary patterns of Pacific Islander Americans are partially influenced by a rich cultural heritage. There is little known about how cultural affinity affects the dietary choices of this small, but quickly growing population. This analysis attempts to understand how the association of cultural affinity on island foods consumption (IFC) varies by key demographic characteristics. A sample of 240 Samoan and Tongan adults in California from the Pacific Islander Health Study (PIHS) was used. Psychometric properties of a novel 11-item cultural affinity scale were assessed. Univariate and bivariate analyses of the cultural affinity scale were completed to understand the distribution of cultural affinity score. Separate multivariable Poisson regression was used to assess the effect of interactions between cultural affinity and five key demographic factors on IFC. Psychometric analysis of the PIHS cultural affinity scale revealed two unique factors. Significant interactions were found between cultural affinity and ethnicity and birthplace: the association between cultural affinity and IFC was larger among Samoans compared to Tongans and Samoan or Tongan birthplace was found to have a weaker association between cultural affinity and IFC. Interactions between cultural affinity and age, financial insecurity, and educational attainment were not significant. Understanding how cultural affinity varies in its effect on IFC is a part of understanding overall dietary patterns in this population.
美属太平洋岛民的饮食模式部分受到丰富文化遗产的影响。对于文化亲和力如何影响这个规模虽小但发展迅速的人群的饮食选择，人们知之甚少。本分析试图了解文化亲和力与岛屿食物消费（IFC）的关联如何因关键人口统计学特征而有所不同。本研究使用了来自加利福尼亚州太平洋岛民健康研究（PIHS）的 240 名萨摩亚和汤加成年人的样本。评估了一种新颖的 11 项文化亲和力量表的心理测量特性。完成了文化亲和力量表的单变量和双变量分析，以了解文化亲和力得分的分布情况。使用单独的多变量泊松回归来评估文化亲和力与五个关键人口统计学因素之间的相互作用对 IFC 的影响。PIHS 文化亲和力量表的心理测量分析揭示了两个独特的因素。发现文化亲和力与种族和出生地之间存在显著的相互作用：与汤加人相比，萨摩亚人之间的文化亲和力与 IFC 之间的关联更大，而萨摩亚或汤加出生地发现文化亲和力与 IFC 之间的关联较弱。文化亲和力与年龄、财务不安全和教育程度之间的相互作用不显著。了解文化亲和力对 IFC 的影响如何变化是了解该人群整体饮食模式的一部分。
