    食料品アクセス問題は、高齢者の食生活や健康といった個人やミクロ面にも悪影響を及ぼす、超高齢社会である我が国において早急に解決すべき重要な課題である。 本研究では、アクセスマップを応用してアクセス条件の変化が食生活に及ぼす影響とその改善効果を検証することを目的とするが、なかでも食料品アクセス問題が個人・ミクロ面に及ぼす影響に焦点をあて、所属機関での研究成果であるアクセスマップを応用した住民調査を実施することで、アクセス条件の変化を考慮した住民調査と食生活改善の提案に関する調査を行う。アクセスマップから抽出された過去10年、3時点でアクセス条件が大きく変化した地域について、各自治体のアクセス対策や社会経済要因等を考慮しながら住民調査を実施するとともに、自治体関係者等との協議調整後、高齢者を対象にした食事摂取頻度調査を組み込んだ住民調査を再度実施する。

    This study examined the impact on dietary habits directly related to quality of life in the food access problem and the effect of dietary habit improvement proposals at the individual and community levels. The relationship between subjective shopping inconvenience and diversity of food intake showed that single-male households tend to consume food less frequently than other household types, suggesting the need for support for these households regarding food procurement and intake. At the same time, a consumer preference survey on mobile food vending services that relax access conditions was conducted using the BWS method, and it was confirmed that the freshness of perishable foods was second in importance, followed by conversation with sales staff, and this tendency was higher among the elderly in later stages of life.

    A remarkable increase in ready-to-eat food and food delivery sales has greatly contributed to the growth of the food manufacturing and food service industries. However, as these industries are labor-intensive, their added value per worker is lower than that of other industry sectors. Furthermore, given the decline in the working-age population, there may be significant increases in wages and product prices. Regarding consumers’ nutrition intake, the rising frequency of take-out food (including staple food) consumption would increase carbohydrate intake. However, a rise in the consumption of side dishes may reduce carbohydrate intake. Finally, regarding the influence of COVID-19 on food consumption patterns, the decrease in the frequency of eating-out led to an increase in food delivery.

    This report investigates factors, including non-economic factors, that determine the fruit and vegetable consumption of socially disadvantaged individuals. The main outcomes of the study are as follows: 1) When considering the relationship between the attributes of a consumer and their fruit and vegetable consumption, it was observed that the age of the person and social capital have an impact. 2) In the case of people with low income, a relationship was observed between focus on diet and the proportion of vegetable intake. 3) Compared to the group with ordinary incomes, the low-income group included more people who disliked vegetables and underestimated the quantity of vegetables necessary for good health. The vegetable intake of this segment was also low, probably because they did not have an interest in diets since childhood. 4) Cognitive reframing had only a partial impact on the purchase of fruits and vegetables.

    This study aimed to investigate the association of a self-reported difficulty of food access, provides the perception of food-store accessibility, with nutrient intake among residents aged 40 years or older in a rural area of Japan. This study found a nutritional balance among men with the difficulty of food access was lower fat and higher carbohydrate than those with non-difficulty of food access. To the next step, we investigated the association between geographical food access and intake frequencies of vegetables/fruits and meat/fish among community-dwelling older adults living in urban/suburban areas and in rural areas. Residents with unwalkable food access had a significantly higher frequency of vegetables/fruits intake than those with walkable food access in urban/suburban areas.

    This is a study into determinants, including noneconomic factors, of Fresh Fruits and Vegetables consumption, and its main findings are summarized as follows. An analysis of demand systems revealed that salad is increasingly consumed by households, and that households with fewer members consumed more salad. Covariance structure analysis revealed that the amounts of both vegetables and fruit consumed were affected by people’s attitudes toward health and safety, while that of vegetables consumed was affected by people’s attitudes toward cooking, and that of fruit consumed was affected by people’s attitudes toward eating with other people. These results suggest that highlighting the healthiness and safety of Fresh Fruits and Vegetables is effective in increasing their consumption, proposing recipes and offering pre-cut vegetables are effective in increasing consumption of vegetables, and spotlighting the enjoyment of eating with others is effective for increasing fruit consumption.

    We analyzed the difficulties in accessing grocery stores from national, individual, and local perspectives, and derived the implications from doing so for resolving the problem. From the national perspective, we quantitatively revealed the possible increase of people who will experience difficulty in shopping, mainly in urban areas in the future. From the individual perspective, we analyzed the example of a big-city suburban housing complex and clarified the possibility that elderly females experiencing difficulty in shopping are further increasing their food outsourcing and lowering dietary variety, which will have an adverse effect on their health. From the local perspective, we analyzed the example of a shop operated mainly by elderly volunteers in a provincial city. The analysis suggested that the social participation of healthy, active senior citizens will become an important agenda in the future.

    The new type of community which includes stakeholders who live outside the target community is called "Theme Community". This study aimed at investigating the development of economic diversification in the rural society which was characterized as theme community, and evaluating the economic and social impacts of rural diversification by an integrated framework. The geographic boundary of the theme community has extended globally. The outside stakeholders’ engagement stimulated the rural residents and boosted new economic activities. DP moral method was also introduced to evaluate the performance of rural women’s innovative activities.

    We investigated the management strategy of economic activities contributing to rural diversification and social backgrounds embedding regional economy. Main findings are as follows. (1) In Japanese rural communities where the farmers' markets (FM) locate, Aged shippers have lowered both the level of social activity and that of shipping for FM. On the other hand, some late starters have been active in shipment and have developed wider social network. (2) The practice of diversified economic activities has developed the circulation of regional economy. (3) The Japanese Government introduced a program for agriculture, industry and commerce collaboration. But the agricultural sector is still lack in voluntarily at the stage of collaboration to other sectors. (4) Ireland's local action group (LAG) is based on project management and contributes to the enhancement of new collaborative activities among regional stakeholders. (5) In the USA, the direct marketing system to consumers has changed its alternativeness and the opportunity of face-to-face communication has been decreased.

    アジアおよび欧米諸国で多様に展開している農産物および加工食品の消費者向け直売活動について、運営の仕組みや農家・地域社会に与える影響を国際比較した。アジア諸国では農村・農家主導で直売が展開しているのに比べ、欧米諸国では都市部の消費者が直売型流通を主導している。流通業の国際化と食文化の標準化は国を超えて浸透しているが、その中でも地域の食材を評価し実際に購入できる場として農産物直売は評価されている。
