Improvements were noted in the course of this investigation, and these were predominantly associated with the fact that those in the study community began to pay attention to the problem of low haemoglobin levels and to improve their diet, with an increase in daily food intake, particularly of animal protein and iron. In addition, a marked decrease in anaemia caused by hookworm also played an important role. In this paper, the change in haemoglobin concentration during the period of study are described and the aetiology is discussed.<\/jats:p>","DOI":"10.1136\/jech.33.4.286","type":"journal-article","created":{"date-parts":[[2008,11,12]],"date-time":"2008-11-12T15:09:01Z","timestamp":1226502541000},"page":"286-291","source":"Crossref","is-referenced-by-count":0,"title":["Follow-up studies on the distribution of haemoglobin levels in female farm workers."],"prefix":"10.1136","volume":"33","author":[{"given":"M","family":"Futatsuka","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W","family":"Koyama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y","family":"Arimatsu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Ueda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T","family":"Hitoshi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T","family":"Ueda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R","family":"Yasutake","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Tanaka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J","family":"Misumi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Nomura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[1979,12,1]]},"reference":[{"key":"ref_1","article-title":"In addition to earlier reports presented by Uchida and Owada, this laboratory has been studying the aetiology of anaemia among women engaged in agriculture","volume-title":"The dominant cause of increases in Hb concentration observed during the 10 years of our investigation were related to increases in daily food intake, particularly of animal protein","author":"(Yasutakeet al., (Fig.","year":"1972","unstructured":"In addition to earlier reports presented by Uchida and Owada, this laboratory has been studying the aetiology of anaemia among women engaged in agriculture (Nomura, 1972; Tanakaetal., 1976).
