【Abstract】 Four thpusad and three hundred residents in Xuzhou District, including pregnant women, workers, farmers, cadres and rural adolescent students, totally 1932 males and 2368 females, aged 12-81, were screened for anemia. The incidence was 14.93% (642 out of 4300), in which the majority (86.76%) were of mild degree. The most common cause of anemia in this series was iron deficiency (355 in 642, 55.30%). The other causes were : folic acid and/or vitamin B12 deficiency (11.84%); combined deficiency in iron and folic acid and B12 (2.80%); and secondary anemias owing to hepatic and nephritic diseases, malaria, cancer and others (30.06%).Investigation into the deficiency factors disclosed that lack of iron or folic acid and B12 was mainly of nutirional origin, i. e insufficient intake of vegetableS and meat and inadequate cooking habits. Chronic blood losses, especially menorrhes in females and ancylostomiasis, were important in causing iron deficiency. Eycess-ve cooking related to folicacid deficiency and certain drugs could have disturbed the metabolism of folic acid. Low level of folic acid was often found in the pregnant group; its mechanism is discussed.更多还原
