This study investigated the relationship between prefecture-level yield of not-for-sale fruits and vegetables and individual-level fruit and vegetable intake in Japan. Data were drawn from the Japanese National Health and Nutrition Survey and National Crop Survey of 2016. Random intercept models were used for the analyses. Individual-level fruit and vegetable intake was used for the dependent variable, and prefecture-level yield of not-for-sale fruits and vegetables was used for the independent variable as a fixed effect. In addition, participants' characteristics and health-related factors at the individual level were also put into independent variables as fixed effects. The prefectures were used as random intercepts. It was found that prefecture-level yield of not-for-sale fruits and vegetables was significantly related to individual-level fruit and vegetable intake (vegetable: B = 0.390, < 0.001; fruit: B = 0.268, = 0.003; fruits and vegetables: B = 0.357, < 0.001). These relationships were also significant in the gender-specific analysis. Thus, the yield of not-for-sale fruits and vegetables might contribute to the intake of fruits and vegetables in Japan.
本研究旨在探讨日本地区非销售性水果和蔬菜产量与个体水果和蔬菜摄入量之间的关系。数据来源于 2016 年日本全国健康和营养调查以及全国农作物调查。分析采用随机截距模型。个体水果和蔬菜摄入量作为因变量，地区非销售性水果和蔬菜产量作为固定效应的自变量。此外，个体水平的参与者特征和与健康相关的因素也被作为固定效应纳入自变量。地区被用作随机截距。结果发现，地区非销售性水果和蔬菜产量与个体水果和蔬菜摄入量显著相关（蔬菜：B = 0.390， < 0.001；水果：B = 0.268， = 0.003；水果和蔬菜：B = 0.357， < 0.001）。在性别特异性分析中，这些关系也是显著的。因此，非销售性水果和蔬菜的产量可能有助于日本水果和蔬菜的摄入。
