目的：评估医疗保健提供者根据外貌估算女性体重指数 (BMI) 的能力，并确定与体重相关的咨询的普遍性和障碍。方法：向大学医院的医疗保健提供者（“参与者”）分发了一项基于网络的调查，其中包含匿名女性（照片女性（PW）”）的照片以及有关参与者人口统计数据的问题。参与者被要求根据外貌估计 BMI 类别，说明他们是否会提供减肥咨询结果：142 名参与者完成了调查，总体准确度仅为 41%，并且大部分的低估结果并未提高准确度；自己的衣服为 41%，而工作服为 40%，P = 0.2。白人与非裔美国人的 BMI 评估更准确（45% 与 36%，P <）。 0.001）和正常体重（84%）和肥胖 III（38%）的儿童与中等 BMI 的儿童相比（P < 0.001） 虽然减肥咨询的频率与儿童 BMI 呈正相关，但参与者仅打算向 69% 的超重和肥胖儿童提供咨询。最常提到的缺乏咨询的原因是时间限制（54%）。结论：医疗保健提供者在基于外表的方面不准确。 BMI 分类以及因此应定期计算 BMI，以便更好地识别需要咨询的人。如果识别得当，时间限制可能会妨碍从业者提供适当的减肥咨询，从而使本来就很困难的抗击肥胖的任务变得更加复杂。
Objective: To assess healthcare providers' ability to estimate women's body mass index (BMI) based on physical appearance and determine the prevalence of, and barriers to, weight-related counseling.Methods: A web-based survey was distributed to healthcare providers ("participants'') at a university-based hospital and contained photographs of anonymous women (photographed women (PW)'') as well as questions regarding participant demographics. Participants were asked to estimate BMI category based on physical appearance, state whether they would provide weight-loss counseling for each PW and identify barriers to counseling.Results: One hundred forty-two participants completed the survey. BMI estimations were poor among all participants, with an overall accuracy of only 41% and a large proportion of underestimations. Standardization of PW clothing did not improve accuracy; 41% for own clothing versus 40% for scrubs, P = 0.2. BMI assessments were more accurate for Caucasian versus African American PW (45% versus 36%, P < 0.001) and PW with normal weight (84%) and obesity III (38%) compared to PW with mid-range BMI (P < 0.001). Although the frequency of weight loss counseling was positively associated with PW BMI, participants only intended to counsel 69% of overweight and obese PW. The most commonly cited reason for lack of counseling was time constraints (54%).Conclusions: Healthcare providers are inaccurate at appearance-based BMI categorization and thus, BMI should be routinely calculated in order to improve identification of those in need of counseling. When appropriately identified, time constraints may prevent practitioners from providing appropriate weight-loss counseling-further complicating the already difficult task of fighting obesity.
