Delphi method was used to conduct consensus analysis with 11 experts in related field involved to determine the nutrition knowledge questionnaire items.RESULTS The active coefficients of consultation in two rounds were both 100%(11/11), and the authority coefficients of experts were 0.900. The average scores of all items were(4.67±0.28) and(4.80±0.21), the variation coefficients were 0.06 and 0.04, and the Kendall harmony coefficients were 0.261(χ²=39.645, P=0.004) and 0.324(χ²=43.122, P=0.001), respectively. After the second round of consultation, all selected items met the inclusion criteria. Finally, 20-item nutrition knowledge questionnaire were determined, including five dimensions of dietary recommendations, food characteristics, nutrition and health, food choices and food safety.CONCLUSION The Delphi consensus of nutrition knowledge questionnaire items for Chinese adults were basically achieved.
