Occupational health nurses are at the forefront of obesity assessment and intervention and must be aware of potential inaccuracies of obesity measurement. The purpose of this study was to identify the prevalence of obesity among a sample of 84 male police officers 22 to 63 years old and determine the accuracy of body mass index (BMI) in estimating obesity compared to body fat percent (BF %). BMI identified 39.3% of the participants as obese, compared to 70.2% by BF %. BMI misclassified normal-weight officers as obese or overweight and obese officers as normal 48.8% (n = 41) of the time. The two misclassified groups had similar average BMIs but significantly different BF %. BMI was not an accurate measure of obesity among adult males. BMI underestimated the true prevalence of obesity and could represent a missed opportunity for early intervention and disease prevention.
职业健康护士处于肥胖评估和干预的前沿，必须意识到肥胖测量可能存在的不准确之处。本研究的目的是确定84名年龄在22至63岁之间的男性警察样本中的肥胖患病率，并确定与体脂百分比（BF%）相比，体重指数（BMI）在估计肥胖方面的准确性。BMI将39.3%的参与者判定为肥胖，而BF%判定的比例为70.2%。BMI将正常体重的警察误分类为肥胖或超重，将肥胖警察误分类为正常的情况占48.8%（n = 41）。这两个误分类组的平均BMI相似，但BF%有显著差异。BMI并非成年男性肥胖的准确衡量指标。BMI低估了肥胖的真实患病率，可能意味着错失了早期干预和疾病预防的机会。
