To test the hypothesis that the socio-cultural transition in the 1990s in Eastern Europe was associated with an increase in admissions for eating disorders (ED).
Cases of ICD-9 and ICD-10 ED in 1981, 1986 and 1992-2005 and first admissions for ICD-10 anorexia nervosa (AN) in 1994-2005 were retrieved from the Czech national register of hospital admissions. Age- and sex-adjusted admission rates (per 100,000) were calculated and time trends tested by Poisson regression.
The admission rate for ED in females aged 10-39 quadrupled from 2.6 (95% CI 2.1-3.0) in 1981 to 10.6 (95% CI 9.8-11.5) in 2001, and remained elevated till 2005. The rate of first-time admissions for AN in 10- to 39-old females increased from 4.5 (95% CI 3.6-5.4) in 1994 to 7.5 (95% CI 6.3-8.6) in 1999, followed by a non-significant decrease.
Temporal association of an increase in admissions with socio-cultural transition suggests that risk of severe ED including AN is culture-dependent.
检验这样一个假设，即 20 世纪 90 年代东欧的社会文化转型与进食障碍（ED）入院人数的增加有关。
从捷克国家住院登记处检索了 1981 年、1986 年和 1992-2005 年 ICD-9 和 ICD-10 的 ED 病例，以及 1994-2005 年 ICD-10 神经性厌食症（AN）的首次入院病例。计算了年龄和性别调整后的入院率（每 10 万人），并通过泊松回归检验时间趋势。
10-39 岁女性的 ED 入院率从 1981 年的 2.6（95%可信区间 2.1-3.0）翻了两番，达到 2001 年的 10.6（95%可信区间 9.8-11.5），并一直维持到 2005 年。10-39 岁女性首次入院治疗 AN 的比例从 1994 年的 4.5（95%可信区间 3.6-5.4）增加到 1999 年的 7.5（95%可信区间 6.3-8.6），随后呈非显著下降趋势。
入院人数的增加与社会文化转型之间存在时间关联，这表明包括 AN 在内的严重 ED 的风险是文化依赖性的。
