背景：临床经验表明，不同学校的饮食失调(ED)率不同。鉴于其高患病率和高死亡率，了解风险因素很重要。我们假设，不同学校的勃起功能障碍发生率不同，在考虑到个体特征后，学校女生比例和受过高中后教育的父母比例与勃起功能障碍有关。方法：对瑞典斯德哥尔摩郡1983年出生、2002-10年高中毕业的55059名女性的基于登记的记录关联数据进行多水平分析。结果是临床诊断为ED，或去16-20岁的ED专科诊所就诊。结果：16~20岁儿童勃起功能障碍的5年累积发病率为2.4%。考虑到个别危险因素，女生比例每增加10%，患勃起功能障碍的优势比为1·07(1·01比1·13)，P=0.018。父母中至少有一人受过高中后教育的儿童比例每增加10%，患勃起功能障碍的优势比为1.14(1.09比1.19)，P<；0.0001。在一所有25%女孩的学校，25%的父母接受过高中后教育，预测一个女孩患上勃起功能障碍的平均概率为1.3%，在一所拥有75%女孩的学校，75%的父母接受过高中后教育，预测的平均女孩患上勃起功能障碍的可能性为3.3%。结论：不同学校的勃起功能障碍发生率不同；这不是由个体特征来解释的。在女生比例较高的学校，以及父母受过高等教育的学生，无论个人风险因素如何，女孩患勃起功能障碍的几率都更高。
Background: Clinical anecdote suggests that rates of eating disorders (ED) vary between schools. Given their high prevalence and mortality, understanding risk factors is important. We hypothesised that rates of ED would vary between schools, and that school proportion of female students and proportion of parents with post-high school education would be associated with ED, after accounting for individual characteristics. Method: Multilevel analysis of register-based, record-linkage data on 55 059 females born in Stockholm County, Sweden, from 1983, finishing high school in 2002-10. Outcome was clinical diagnosis of an ED, or attendance at a specialist ED clinic, aged 16-20 years. Results: The 5-year cumulative incidence of ED diagnosis aged 16-20 years was 2.4%. Accounting for individual risk factors, with each 10% increase in the proportion of girls at a school, the odds ratio for ED was 1.07 (1.01 to 1.13), P = 0.018. With each 10% increase in the proportion of children with at least one parent with post-high school education, the odds ratio for ED was 1.14 (1.09 to 1.19), P < 0.0001. Predicted probability of an average girl developing an ED was 1.3% at a school with 25% girls where 25% of parents have post-high school education, and 3.3% at a school with 75% girls where 75% of parents have post-high school education. Conclusions: Rates of ED vary between schools; this is not explained by individual characteristics. Girls at schools with high proportions of female students, and students with highly educated parents, have higher odds of ED regardless of individual risk factors.
