To investigate the prevalence, incidence and development of eating disorders and subclinical eating pathology.
A two-step three-year follow-up study on eating disorders in adolescence (N = 595) was conducted in western Finland. A screening questionnaire followed by a semi-structured interview was used to determine the prevalence, incidence and development of eating disorders.
The lifetime prevalence rates for females age 18 were 2.6% for anorexia nervosa (AN), 0.4 for bulimia nervosa (BN), 7.7% for AN-NOS, 1.3% for BN-NOS and 8.5% for subclinical eating disorders. No prevalent case of DSM-IV eating disorders was found among the male participants. The incidence rate of any eating disorder in females age 15-18 was 1641 per 100 000 person-years.
Eating disorders are relatively common in female adolescents. As many as one in five adolescent females are or have been struggling with eating disorder related issues during their teenage years.
调查饮食失调及亚临床饮食病理的患病率、发病率及发展情况。
在芬兰西部对青少年饮食失调情况进行了一项为期三年的两步随访研究（N = 595）。采用一份筛查问卷及随后的半结构化访谈来确定饮食失调的患病率、发病率及发展情况。
18岁女性中，神经性厌食症（AN）的终生患病率为2.6%，神经性贪食症（BN）为0.4%，非典型神经性厌食症（AN-NOS）为7.7%，非典型神经性贪食症（BN-NOS）为1.3%，亚临床饮食失调为8.5%。男性参与者中未发现符合《精神疾病诊断与统计手册》第四版（DSM-IV）的饮食失调病例。15 - 18岁女性中任何饮食失调的发病率为每10万人年1641例。
饮食失调在女性青少年中相对常见。多达五分之一的青少年女性在其青少年时期正在或曾经与饮食失调相关问题作斗争。
