An epidemiological study of anorexia nervosa and bulimia nervosa in primary care was performed using the General Practice Research Database (GPRD).
The GPRD was screened between 1988 and 1994 for newly diagnosed cases of anorexia nervosa and bulimia nervosa. The validity of the computer diagnosis was established by obtaining clinical details from a random sample of the general practitioners (GPs).
Incidence rates for detection of cases by GPs in 1993 was 4.2 per 100,000 population for anorexia nervosa, and 12.2 per 100,000 for bulimia nervosa. The relative risks of females to males was 40:1 for anorexia nervosa and 47:1 for bulimia nervosa. A threefold increase in the recording of bulimia nervosa was found from 1988 to 1993. Eighty per cent of anorexia nervosa cases and 60% of bulimia nervosa cases were referred to secondary care.
There is a continuing expansion of service need for bulimia nervosa. The majority of cases of eating disorders are referred to secondary services. There is scope for more effective management of bulimia nervosa in primary care.
利用全科医疗研究数据库（GPRD）对初级保健中神经性厌食症和神经性贪食症进行了一项流行病学研究。
在1988年至1994年间对GPRD进行筛查，以查找新诊断的神经性厌食症和神经性贪食症病例。通过从全科医生（GP）的随机样本中获取临床细节来确定计算机诊断的有效性。
1993年全科医生检测到的神经性厌食症发病率为每10万人中4.2例，神经性贪食症为每10万人中12.2例。神经性厌食症女性与男性的相对风险为40:1，神经性贪食症为47:1。从1988年到1993年，神经性贪食症的记录增加了两倍。80%的神经性厌食症病例和60%的神经性贪食症病例被转诊至二级医疗保健机构。
对神经性贪食症的服务需求在持续增加。大多数饮食失调病例被转诊至二级医疗服务机构。在初级保健中对神经性贪食症进行更有效管理存在空间。
