背景资料。中介和调节变量可能会干扰附近杂货店(NAG)和超市(NAS)的可获得性与水果和蔬菜(FV)摄入量之间的关联。目标。本研究的目的是在非裔美国人(AA)和西班牙裔/拉丁裔(HL)女性中测试家庭可获得性(HAFV)的中介作用和每周应激事件(IWSE)对NAG和NAS与FV消费之间的影响的调节作用。方法：研究方法。在Health is Power(HIP)随机对照试验中，300名AA和HL，25-60岁的女性完成了基线时HAFV、IWSE和FV摄入量的验证测量。训练有素的现场评估员编码为NAG和NAS。已获得机构审查委员会的批准。结果。NAG和NAS与FV摄入量和HAFV无关，因此HAFV不是一个介体。HAFV(STD.Beta=.29，P<；0.001)和IWSE(标准β=0.17；P<；0.001)与FV摄入量相关(R2=0.17；P<；0.05)，但IWSE不是调节因素。结论。增加HAFV和降低IWSE应该会增加FV消耗。社区环境与家庭食物环境和饮食的关联程度，以及IWSE和饮食之间的关联机制应在未来的研究中进行检验。
Background. Mediating and moderating variables may interfere with the association between neighborhood availability of grocery stores (NAG) and supermarkets (NAS) and fruit and vegetable (FV) intake. Objective. The purpose of this study was to test mediation of home availability of FV (HAFV) and moderation of impact of weekly stressful events (IWSE) on the association between NAG and NAS with FV consumption among African American (AA) and Hispanic/Latina (HL) women. Methods. Three hundred nine AA and HL, 25–60 year old women in the Health Is Power (HIP) randomized controlled trial completed validated measures of HAFV, IWSE, and FV intake at baseline. Trained field assessors coded NAG and NAS. Institutional Review Board approval was obtained. Results. NAG and NAS were not associated with FV intake or HAFV, so HAFV was not a mediator. HAFV (std. Beta = .29, P < 0.001) and IWSE (std. Beta = .17; P < 0.05) were related to FV intake (R2 = 0.17; P < 0.001), but IWSE was not a moderator. Conclusion. Increasing HAFV and decreasing the IWSE should increase FV consumption. The extent to which the neighborhood environment is related to the home food environment and diet, and the mechanisms for the association between IWSE and diet should be examined in future research.
