To determine the incidence and prevalence of eating disorder and its clinical forms.
All new ED cases of both genders, ≥15 years old, diagnosed from January 2005 to December 2009 were included. All patients who suffered from ED in December 2009 were included in the prevalence study. This is a prospective, population-based study. Cumulative incidence rates and 20-year prevalence were calculated.
The ED incidence was 14.1 (95% CI 11.4-16.1) cases per 100,000 inhabitants per year, for AN, BN and EDNOS 3.1 (95% CI 2.00-4.1), 4.4 (95% CI 3.0-8.00) and 6.5 (95% CI 4.8-7.9), respectively. The incidence of ED at the four age-intervals, 15-24, 25-34, 35-45 and >45 years, revealed that the 25-34-year interval had the highest incidence; moreover, new cases were observed even in the >45-year interval. The prevalence of ED was 82.8 (95% CI 69.4-94.5) per 100,000 inhabitants, being for AN, BN and EDNOS 18.6 (95% CI 12.5-24.4), 25.7 (95% CI 18.5-32.5) and 38.3 (95% CI 29.4-46.5), respectively.
The incidence and prevalence of EDNOS are the highest in the ED cases; furthermore, new cases of ED are observed above the age of 45, which are remarkable data.
确定进食障碍及其临床形式的发病率和患病率。
纳入 2005 年 1 月至 2009 年 12 月期间所有新诊断为 15 岁及以上的男女进食障碍患者。将 2009 年 12 月患有进食障碍的所有患者纳入患病率研究。这是一项前瞻性、基于人群的研究。计算累积发病率和 20 年患病率。
AN、BN 和 EDNOS 的发病率分别为每 10 万人每年 14.1（95%CI 11.4-16.1）、3.1（95%CI 2.00-4.1）、4.4（95%CI 3.0-8.00）和 6.5（95%CI 4.8-7.9）例。在 15-24、25-34、35-45 和 >45 岁这四个年龄区间中，ED 发病情况显示 25-34 岁年龄区间的发病率最高；此外，甚至在 >45 岁年龄区间也观察到新发病例。ED 的患病率为每 10 万人 82.8（95%CI 69.4-94.5），AN、BN 和 EDNOS 的患病率分别为 18.6（95%CI 12.5-24.4）、25.7（95%CI 18.5-32.5）和 38.3（95%CI 29.4-46.5）。
EDNOS 的发病率和患病率在 ED 病例中最高；此外，在 >45 岁年龄也观察到新发病例，这是值得注意的数据。
