健康的な食行動の実践を支援するための日本版栄養プロファイルモデル試案の実行可能性調査：食習慣改善意欲の有無による横断的検討

Abstract

Objective: To assess the feasibility of the draft Japanese Nutrient Profile (NP) model, we developed informational materials about its utilization, and conducted Internet research to identify issues and needs according to the motivation of behavioral change. Methods:We developed the informational materials (4 pages, 1 A3-sided sheet) based on the NP model, as well as materials from other countries. An online cross-sectional survey was conducted among 3,000 Japanese consumers aged 18 years or older. The age, sex, and regional distribution of the participants, as well as their motivation for behavioral change, were similar to those of the National census and the National Health and Nutrition survey, respectively. The participants read the informational materials and were asked how such materials would affect their food purchasing behavior.Based on the participants' current motivation for behavioral change, they were divided into three groups: not interested (n = 1,187), intend to improve (n = 1,465), and recognition of no problem with own eating behavior (n = 348).Results: More than 90% of the respondents found the informational materials easy to understand. The number of respondents who answered that the symbols that warned against overconsumption would influence their food purchasing behavior was greater for all food groups among the group with the intention to improve, accounting for approximately 70%, in contrast to only about 40% among those who were not motivated. Conclusions: Our results indicated that the food labeling based on the NP model might influence consumers' healthy eating behaviors, especially among those who intend to improve their eating behaviors.
