背景：家庭食物清单提供了评估家庭食物可用性的有效方法；然而，很少有人得到证实。本研究的目的是开发和验证一份家庭食品清单，该清单很容易由研究参与者在家中完成，其中包括与肥胖有关的健康和不健康食品的全面范围。方法：编制家庭食品调查表（HFI），并对2份样品进行检测。样本1包括51名成年参与者和6名训练有素的研究人员，他们在参与者家中独立完成HFI。样本2包括342个家庭，其中家长完成HFI和饮食史问卷（DHQ），学生完成3次24小时饮食回忆访谈。HFI项目评估了13个主要食品类别，以及评估厨房和冰箱中现成食品的两个类别。还创建了致肥性家庭食物可用性评分。为了评估标准效度，比较了参与者和研究人员对家庭食品可得性的评估（工作人员=金标准）。用kappa、敏感性和特异性评估标准效度。结构效度评估了五种HFI主要食物类别得分与DHQ和饮食召回中相同食物和相关营养成分的相关性。结果：所有13个主要食品类和两个现成食品类的Kappa统计值在0.61 ~ 0.83之间，表明有很大的一致性。敏感性为0.69 ~ 0.89，特异性为0.86 ~ 0.95。工作人员和参与者主要食物类别得分之间的Spearman相关性在0.71到0.97之间。HFI得分与DHQ（父母）上的食物组份量和营养成分之间的相关性都是显著的（p < 0.05），而HFI和饮食回忆访谈（青少年）之间的相关性约有一半是显著的（p < 0.05）。致肥性家庭食物可得性得分与父母和青少年的能量摄入显著相关（p < 0.05）。结论：这种新的家庭食品调查表是有效的，对参与者友好，可用于社区行为营养和肥胖预防研究。该清单以以前的措施为基础，包括广泛的健康和不健康食品，而不是针对特定干预的食品。
Background: Home food inventories provide an efficient method for assessing home food availability; however, few are validated. The present study's aim was to develop and validate a home food inventory that is easily completed by research participants in their homes and includes a comprehensive range of both healthful and less healthful foods that are associated with obesity.Methods: A home food inventory (HFI) was developed and tested with two samples. Sample 1 included 51 adult participants and six trained research staff who independently completed the HFI in participants' homes. Sample 2 included 342 families in which parents completed the HFI and the Diet History Questionnaire (DHQ) and students completed three 24-hour dietary recall interviews. HFI items assessed 13 major food categories as well as two categories assessing ready-access to foods in the kitchen and the refrigerator. An obesogenic household food availability score was also created. To assess criterion validity, participants' and research staffs' assessment of home food availability were compared (staff = gold standard). Criterion validity was evaluated with kappa, sensitivity, and specificity. Construct validity was assessed with correlations of five HFI major food category scores with servings of the same foods and associated nutrients from the DHQ and dietary recalls.Results: Kappa statistics for all 13 major food categories and the two ready-access categories ranged from 0.61 to 0.83, indicating substantial agreement. Sensitivity ranged from 0.69 to 0.89, and specificity ranged from 0.86 to 0.95. Spearman correlations between staff and participant major food category scores ranged from 0.71 to 0.97. Correlations between the HFI scores and food group servings and nutrients on the DHQ (parents) were all significant (p < .05) while about half of associations between the HFI and dietary recall interviews (adolescents) were significant (p < .05). The obesogenic home food availability score was significantly associated (p < .05) with energy intake of both parents and adolescents.Conclusion: This new home food inventory is valid, participant-friendly, and may be useful for community-based behavioral nutrition and obesity prevention research. The inventory builds on previous measures by including a wide range of healthful and less healthful foods rather than foods targeted for a specific intervention.
