To examine the prevalence of overweight and obesity in firefighters.
Body mass index (BMI), waist circumference, and body fat percentage (BF%) were assessed in 478 career and 199 volunteer male firefighters from randomly selected departments.
High prevalence rates of overweight + obesity (BMI ≥ 25 kg/m) and obesity (BMI ≥ 30 kg/m) were found in career (79.5%; 33.5%) and volunteer firefighters (78.4%; 43.2%). False-positive obesity misclassification based on BMI, compared to waist circumference and BF%, was low (9.8% and 2.9%, respectively). False negatives were much higher: 32.9% and 13.0%. Obese firefighters demonstrated unfavorable cardiovascular disease (CVD) profiles.
The prevalence of overweight and obesity exceeded that of the US general population. Contrary to common wisdom, obesity was even more prevalent when assessed by BF% than by BMI, and misclassifying muscular firefighters as obese by using BMI occurred infrequently.
研究消防员超重和肥胖的流行情况。
从随机选择的部门中评估了 478 名职业和 199 名志愿男性消防员的体重指数(BMI)、腰围和体脂百分比(BF%)。
职业(79.5%;33.5%)和志愿消防员(78.4%;43.2%)中存在较高的超重+肥胖(BMI≥25kg/m)和肥胖(BMI≥30kg/m)患病率。与腰围和 BF%相比,BMI 作为肥胖的假阳性分类错误率较低(分别为 9.8%和 2.9%)。假阴性率则高得多:分别为 32.9%和 13.0%。肥胖的消防员表现出不利的心血管疾病(CVD)特征。
超重和肥胖的患病率超过了美国一般人群。与普遍看法相反,根据 BF%评估肥胖的患病率甚至比 BMI 更高,而且使用 BMI 将肌肉发达的消防员错误地归类为肥胖的情况很少发生。
