Racial and ethnic disparities in fruit and vegetable consumption have been widely studied in the USA. While previous studies focused on the differences of fruit and vegetable availability between racial groups, the equivalence of the association between consumption and availability across racial groups has been rarely examined. The purpose of this study was to investigate the relationship between availability of fruits and vegetables and their consumption across racial groups. The 2011-2012 California Health Interview Survey data (N = 36,302) were used for the study. Results of negative binomial regression show that the association between perceived availability of fruits and vegetables on consumption differs significantly between non-Hispanic Whites, Hispanics, Blacks, and Asians: (1) the association between fruit consumption and availability is only significant for non-Hispanic Whites (IRR = 1.303, 95 % CI 1.188, 1.429), and (2) the association between vegetable consumption and availability is only significant for non-Hispanic Whites (IRR = 1.242, 95 % CI 1.152, 1.340) and Hispanics (IRR = 1.141, 95 % CI 1.025, 1.271). This study highlights the importance of interventions that emphasize not only potential access but also social and cultural factors that relate to realized access to healthy food.
种族和民族之间在水果和蔬菜消费方面的差异在美国已经得到广泛研究。虽然之前的研究集中在不同种族群体之间水果和蔬菜供应的差异上,但很少有研究检验消费与供应之间的关联在不同种族群体之间是否具有等效性。本研究旨在调查水果和蔬菜供应与不同种族群体消费之间的关系。本研究使用了 2011-2012 年加利福尼亚健康访谈调查数据(N=36302)。负二项回归的结果表明,水果和蔬菜感知供应与消费之间的关联在非西班牙裔白人、西班牙裔、黑人和亚洲人之间存在显著差异:(1)水果消费与供应之间的关联仅在非西班牙裔白人中具有显著意义(IRR=1.303,95%CI 1.188,1.429),(2)蔬菜消费与供应之间的关联仅在非西班牙裔白人(IRR=1.242,95%CI 1.152,1.340)和西班牙裔(IRR=1.141,95%CI 1.025,1.271)中具有显著意义。本研究强调了干预措施的重要性,这些措施不仅要强调潜在的获取途径,还要强调与获取健康食品有关的社会和文化因素。
