The objective of this study was to assess the prevalence of young females at risk of developing eating disorders (ED) and the associated socio-demographical variables.
A set of self-administered questionnaires consisting of an Eating Attitude Test (EAT), an Eating Disorder Inventory (EDI) and a socio-demographical questionnaire was administered to 4,461 young females. Based on scores for EAT and/or EDI-drive for thinness (EDI-DT) subscale, subjects were categorised into either "normal" (NM) or "at risk" (AR) of ED.
Mean age of the subjects was 16.7 years (range 12-26 years). The ethnic composition was 78.8 percent Chinese, 11.7 percent Malay, 6.6 percent Indian and 3 percent other ethnic groups. Prevalence of AR was 7.4 percent (95 percent confidence interval [CI] 6.7-8.2 percent). Mean EAT and EDI-DT scores for AR were significantly higher than that of NM (EAT: mean difference is 22.1, 95 percent CI 20.7-23.4, p-value is less than 0.0001; EDI-DT: mean difference is 10.9, 95 percent CI 10.5-11.4, p-value is less than 0.0001). Female Malays constituted a significantly larger proportion of AR (20.6 percent) as compared to NM (10.9 percent). AR females are more likely to use Malay as a spoken language at home (prevalence rate ratio 1.70, p-value is 0.001) and to be better educated with completion of General Certificate of Education (GCE) "O" levels. However, the parents of AR females are likely to be less well educated (below GCE "A" levels).
The prevalence of females at risk of developing ED is 7.4 percent. Malay ethnic group, using Malay language at home and the educational levels of both the subjects and their parents appear to be associated with an increased risk for development of ED.
本研究的目的是评估有发展成饮食失调（ED）风险的年轻女性的患病率以及相关的社会人口统计学变量。
对4461名年轻女性发放了一套自填式问卷，包括饮食态度测试（EAT）、饮食失调量表（EDI）和一份社会人口统计学问卷。根据EAT和/或EDI-瘦身驱力（EDI-DT）子量表的得分，将受试者分为饮食失调“正常”（NM）或“有风险”（AR）两类。
受试者的平均年龄为16.7岁（范围12 - 26岁）。种族构成中，华人占78.8%，马来人占11.7%，印度人占6.6%，其他种族占3%。有风险者的患病率为7.4%（95%置信区间[CI] 6.7 - 8.2%）。有风险者的EAT和EDI-DT平均得分显著高于正常者（EAT：平均差值为22.1，95% CI 20.7 - 23.4，p值小于0.0001；EDI-DT：平均差值为10.9，95% CI 10.5 - 11.4，p值小于0.0001）。与正常者（10.9%）相比，马来族女性在有风险者中所占比例显著更高（20.6%）。有风险的女性在家中更有可能说马来语（患病率比值1.70，p值为0.001），并且接受普通教育证书（GCE）“O”水准教育的程度更高。然而，有风险女性的父母受教育程度可能较低（低于GCE“A”水准）。
有发展成饮食失调风险的女性患病率为7.4%。马来族、在家说马来语以及受试者及其父母的教育水平似乎与饮食失调发展风险增加有关。
