Target weights are an arbitrary means of determining return to physical health in patients with anorexia nervosa (AN) and lack reliability and validity. Transabdominal pelvic ultrasound scanning (U/S) offers a more objective method of ascertaining physical well being by the ability to determine reproductive maturity. This study aimed to explore the correlations between the maturity grading on pelvic U/S and weight for height (WfH) ratios and body mass index (BMI) percentiles. Ultrasound studies were performed in 72 female adolescents (aged 11-17 years at intake) with AN. Scans were graded for maturity using published parameters of pelvic maturity and compared with the patient's WfH ratio and BMI percentile. In our sample was a wide variation of WfH ratios and BMI percentiles at each grade of maturity. This supports the view that arbitrary targets for weight, WfH ratio or BMI percentile are likely to be unnecessarily high for some patients and too low for others. We recommend that targets be based upon baseline pelvic U/S grading and follow-up scanning.
目标体重是确定神经性厌食症（AN）患者身体恢复健康的一种任意手段，缺乏可靠性和有效性。经腹盆腔超声扫描（U/S）通过确定生殖成熟度，提供了一种更客观的确定身体健康的方法。本研究旨在探讨盆腔 U/S 成熟分级与身高体重比（WfH）比值和体重指数（BMI）百分位数之间的相关性。对 72 名患有 AN 的女性青少年（入组时年龄为 11-17 岁）进行了超声研究。使用已发表的骨盆成熟度参数对扫描进行成熟分级，并与患者的 WfH 比值和 BMI 百分位数进行比较。在我们的样本中，每个成熟度等级的 WfH 比值和 BMI 百分位数差异很大。这支持了这样一种观点，即对于某些患者来说，体重、WfH 比值或 BMI 百分位数的任意目标可能过高，而对于另一些患者来说则过低。我们建议根据基线盆腔 U/S 分级和后续扫描来设定目标。
