Abstract

Objective: To clarify the relationship between the proportion of severely insufficient vegetable intake frequency and 1) vegetable cultivation, 2) frequency of receiving vegetable among non-cultivators.

Materials and Methods: Residents aged 20 to 74 years in three areas of a city in Gunma Prefecture, Japan, were invited to participate. In September 2016, two sets of self-administered questionnaires were mailed to all 2,260 households in the three areas. The survey items covered the frequency of vegetable intake, vegetable cultivation (as a farmer, as a non-farmer, or no-cultivation), frequency of receiving vegetable, and basic characteristics. For vegetable cultivators, we asked the proportion of cultivated vegetables for home consumption and for giving to neighbors. Binomial logistic regression models were used to analyze the data collected. The respondents were classified into two groups according to their vegetable intake frequency: fewer than three times per day (severely insufficient), and at least three times per day.

Results: We had 796 valid responses. Using the no-cultivation group as reference, both of the other groups —vegetable cultivation as a farmer, and as a non-farmer— had a significantly smaller proportion of severely insufficient vegetable intake frequency. Among the no-cultivation group, using those who had never received vegetable in the past month as reference, those who rarely, sometimes, or often received vegetables had a significantly smaller proportion of severely insufficient vegetable intake frequency. These associations were similar in cases where vegetable juice was or was not included. The proportion of those who cultivated vegetables for home consumption was 96% among farmers and 100% among non-farmers, respectively, and for giving to neighbors was 84% among farmers and 62% among non-farmers, respectively.

Conclusion: A negative association of the proportion of severely insufficient vegetable intake with vegetable cultivation, and with receiving vegetable among non-cultivators, was suggested.
