The prevalence of eating disorders (EDs) in a representative scholastic sample was evaluated, and the demographic factors associated with ED were assessed.
The study used a two-stage epidemiological design. The study population was a randomly selected sample of 1545 students (12- to 21-year-old males and females) in the region of Madrid (Spain).
ED prevalence was 3.43%. Prevalence estimations were as follows: 5.34% for females: 2.72% for eating disorders not otherwise specified (EDNOS), 2.29% for bulimia nervosa (BN), and 0.33% for anorexia nervosa (AN); and 0.64% for males: 0.48% for EDNOS, 0.16% for BN, and 0.00% for AN. Some demographic factors that were shown to be associated with ED included the following: sex, age, single child, single-parent families, and father or mother's death.
Despite the methodological improvements over previous epidemiological studies developed in Spain, there were no significant differences in the prevalence estimations.
评估具有代表性的学校样本中饮食失调（ED）的患病率，并评估与饮食失调相关的人口统计学因素。
该研究采用两阶段流行病学设计。研究人群是从西班牙马德里地区随机抽取的1545名学生（12至21岁的男性和女性）样本。
饮食失调患病率为3.43%。患病率估计如下：女性为5.34%，其中未另行指定的饮食失调（EDNOS）为2.72%，神经性贪食症（BN）为2.29%，神经性厌食症（AN）为0.33%；男性为0.64%，其中EDNOS为0.48%，BN为0.16%，AN为0.00%。一些与饮食失调相关的人口统计学因素包括：性别、年龄、独生子女、单亲家庭以及父亲或母亲死亡。
尽管与西班牙之前开展的流行病学研究相比，该研究在方法上有所改进，但患病率估计并无显著差异。
