To evaluate the usefulness of neck circumference as an index of excess weight and obesity in young adults while identifying its appropriate cutoff points.
The study comprised 41 male and 109 female students, aged 18-20 years. Anthropometric markers of obesity were measured, including body mass index, waist circumference, hip circumference, waist-to-hip ratio, and compared with neck circumference of the same subjects. Overweight and obesity levels were defined by BMI > or = 23.0 and > or = 25.0 respectively.
Overall 29.2% males and 25.6% females were found overweight/obese. The mean body mass index was 21.7 kg/m2 in males and 21.0 kg/m2 in females. The mean waist and neck circumferences were higher in males (80.6 cm, and 35.5 cm) than females (78.1 cm, and 31.5 cm). Neck circumference had a strong positive correlation (p<0.001) with other relevant indicators in all subjects, except the waist-to-hip ratio which was applicable on males only. At BMI of 23.0 and 25.0, males had neck circumference 35.7cm and 37.5cm, while females had it at of 32.2cm and 33.5cm respectively.
Neck circumference is a potentially useful initial screening tool for overweight/obesity. A neck circumference > or = 35.5 cm in men and > or = 32 cm in women should be considered the cutoff point for overweight/obesity.
评估颈围作为年轻成年人超重和肥胖指标的有效性，并确定其合适的截断点。
该研究纳入了41名年龄在18至20岁之间的男性和109名女性学生。测量了肥胖的人体测量指标，包括体重指数、腰围、臀围、腰臀比，并与同一受试者的颈围进行比较。超重和肥胖水平分别定义为体重指数≥23.0和≥25.0。
总体上，29.2%的男性和25.6%的女性被发现超重/肥胖。男性的平均体重指数为21.7kg/m²，女性为21.0kg/m²。男性的平均腰围和颈围（80.6cm和35.5cm）高于女性（78.1cm和31.5cm）。除仅适用于男性的腰臀比外，颈围与所有受试者的其他相关指标均呈强正相关（p<0.001）。在体重指数为23.0和25.0时，男性的颈围分别为35.7cm和37.5cm，而女性的颈围分别为32.2cm和33.5cm。
颈围是一种潜在有用的超重/肥胖初步筛查工具。男性颈围≥35.5cm、女性颈围≥32cm应被视为超重/肥胖的截断点。
