Dietary variety score (DVS) was determined by counting the number of 10 food groups consumed at least once in 2 days using a food frequency questionnaire. Using the data of 704 men and 1366 women, the sex\u2010specific association of low DVS (&lt;4) with age, region, frailty, annual income, social support, distance to the nearest supermarket and car ownership was analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The prevalence of low DVS was 40.9% for men and 18.4% for women. Frailty and low social support were associated with low DVS. A gradient association with income was found for women, whereas men showed a threshold: &lt;1.5 million yen per year was associated with low DVS. The distance to the nearest supermarket was not significantly associated with DVS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>\n                      The findings of the present study imply that as well as frailty, poor social support and economic disadvantage are associated with a decline in dietary variety. In particular, frail men with income &lt;1.5 million yen per year had a high risk of decreased dietary variety. Formal and informal support to secure food accessibility for physically and socially vulnerable older adults should be encouraged.\n                      <jats:bold>Geriatr Gerontol Int 2017; 17: 2232\u20132238.<\/jats:bold>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/ggi.13004","type":"journal-article","created":{"date-parts":[[2017,2,22]],"date-time":"2017-02-22T04:42:38Z","timestamp":1487738558000},"page":"2232-2238","source":"Crossref","is-referenced-by-count":45,"title":["Physical and social determinants of dietary variety among older adults living alone in Japan"],"prefix":"10.1111","volume":"17","author":[{"given":"Yoshiharu","family":"Fukuda","sequence":"first","affiliation":[{"name":"Teikyo University Graduate School of Public Health  Itabashi Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Midori","family":"Ishikawa","sequence":"additional","affiliation":[{"name":"National Institute of Public Health  Wako Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tetsuji","family":"Yokoyama","sequence":"additional","affiliation":[{"name":"National Institute of Public Health  Wako Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatsumi","family":"Hayashi","sequence":"additional","affiliation":[{"name":"Kyushu Nutrition Welfare University  Kitakyushu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomoki","family":"Nakaya","sequence":"additional","affiliation":[{"name":"Ritsumeikan University  Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yukari","family":"Takemi","sequence":"additional","affiliation":[{"name":"Kagawa Nutrition University  Sakado Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaoru","family":"Kusama","sequence":"additional","affiliation":[{"name":"Aomori University of Health and Welfare  Aomori Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nobuo","family":"Yoshiike","sequence":"additional","affiliation":[{"name":"Aomori University of Health and Welfare  Aomori Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miho","family":"Nozue","sequence":"additional","affiliation":[{"name":"National institutes of Biomedical Innovation Health and Nutrition  Shinjuku Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaori","family":"Yoshiba","sequence":"additional","affiliation":[{"name":"Japan Association for Development of Community Medicine  Chiyoda Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nobuko","family":"Murayama","sequence":"additional","affiliation":[{"name":"University of Niigata prefecture  Niigata Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,2,22]]},"reference":[{"key":"e_1_2_7_2_1","unstructured":"Office C.
