再障的流行病学调查以前做得很少。作者报道了1985年英国部分地区再障发病率的流行病学调查。这些地区的总人口大约为21百万,1985年共发生再障49例,粗发病率(/10万人)为0.23,其中女性35例;男性14例(粗发病率分别为0.32和0.14)。各年龄组发病率分布为:19岁以下男性0.13,女性0.07;20-59岁,男性0.04,女性0.19;60-80岁以上,男性0.45,女性0.90。由此可见,随着年龄增长,女性发病率逐渐高于男性。季节分布为:5月和10月发病例数较多。各地区分布:索克夫为1.63,昆布兰为1.06,格兰马干南部0.80,其它15个地区均在0.43-0.11之间。与其它国家1985年再障的发病率比较;以色列,男性为0.71,女性0.87;巴的尔摩,男性0.48,女性0.38;卡罗来纳南部白人,男性1.17,女
Epidemiological investigation of aplastic anemia has done very little before. The authors report an epidemiological investigation of the incidence of aplastic anemia in parts of the United Kingdom in 1985. The total population in these areas is about 21 million. A total of 49 cases of aplastic anemia occurred in 1985, with a crude incidence of 100,000 (0. 100,000), including 35 females and 14 males (crude incidence rates of 0.32 and 0.14, respectively) . The incidence of each age group distribution: male under 13 years of 0.13, female 0.07; 20-59 years old, male 0.04, female 0.19; 60-80 years of age, male 0.45, female 0.90. Thus, with age, the incidence of women gradually higher than men. Seasonal distribution: May and October, the incidence of more cases. Distribution by region: Sukkof was 1.63, Khumbuang was 1.06, South of Grandma 0.80, the other 15 areas are between 0.43-0.11. Compared with incidence of aplastic anemia in other countries in 1985; Israel, male 0.71, female 0.87; Baltimore, male 0.48, female 0.38; Southern Carolina white, male 1.17, female
