The aim of this study was to evaluate neck circumference (NC) as a discriminator of overweight and obesity and to establish cut-off points for physically active older women. The sample consisted of 170 older women (69.5 ± 6.8 years) practicing physical activity. Anthropometric measures (body weight, height, waist circumference – WC, and NC) were obtained and the body mass index (BMI) was calculated. Correlation analysis was performed and ROC curves were constructed. NC was significantly correlated with BMI (rho = 0.656; p<0.0001) and WC (r = 0.561; p<0.0001). Correlating BMI with NC, areas under the ROC curve of 0.819 (p=0.0001) for overweight and of 0.902 (p=0.0001) for obesity were obtained, with suggested cut-off points of 33.07 and 34.05 cm, respectively. Correlating WC with NC, areas under the ROC curve of 0.711 (p=0.0014) for moderate risk (WC) and of 0.864 (p=0.0001) for high risk were obtained, with suggested cut-off points of 32.15 and 34.15 cm, respectively. NC was associated with BMI and WC. An NC ≥ 34 cm was a risk factor for obesity and abnormal body fat distribution in the older women studied. This anthropometric parameter is an alternative to discriminate overweight and obesity in physically active older women.

Objetivou-se analisar o perímetro de pescoço (PPescoço) como um método discriminador de sobrepeso e obesidade e estabelecer pontos de corte para idosas praticantes de atividade física. A amostra foi composta por 170 idosas (69,5 ± 6,8 anos) praticantes de atividade física. Foram realizadas medidas antropométricas de massa corporal, estatura, perímetro de cintura (PCintura) e do pescoço (PPescoço). Também foi calculado o índice de massa corporal (IMC) erealizada a estatística correlacional e curvas ROC. O PPescoço correlacionou significativamente com o IMC (rho = 0,656; p<0,0001) e com o PCintura (r = 0,561; p<0,0001). Ao relacionar IMC com PPescoço, obteve-se valores para área da curva ROC de 0,819 (p=0,0001) para sobrepeso e 0,902 (p=0,0001) para obesidade, além de pontos de corte sugeridos de 33,07 cm e 34,05 cm, respectivamente. Ao relacionar PCintura com o PPEscoço, obteve-se valores para área curva ROC de 0,711 (p=0,0014) para risco moderado (PCintura) e 0,864 (p=0,0001) para alto risco, além de pontos de corte sugeridos de 32,15 cm e 34,15, respectivamente. O PPescoçoapresentou relação com o IMC e o PCintura. O PPescoço ≥34cm apresentou-se ser o valor de risco para obesidade e distribuição de composição corporal em idosas deste estudo. Essa medida antropométrica é uma alternativa para discriminar o sobrepeso e obesidade de idosas praticantes de atividade física.

Overweight and obesity are considered major public health problems1 and are increasing at an alarming rate throughout the world in both developed and developing countries and in different ages2. Obesity is associated with different comorbidities such as cardiovascular and metabolic diseases2, functional limitations and disabilities, in addition to compromising the quality of life of affected individuals3.

In recent years, there has been discussion about the selection of more accurate (for research purposes) and more convenient (for clinical practice) anthropometric measurements for the diagnosis of obesity4, including body mass index (BMI) and waist circumference (WC)5. Although BMI and WC have limitations6,7, these parameters are used because of their noninvasive, relatively simple and inexpensive measurement8. In addition, they are associated with factors of morbidity and mortality1-5.

Neck circumference (NC) is a marker of upper body subcutaneous adipose tissue distribution and is a relatively new method to differentiate normal and abnormal fat distribution9. Neck circumference is an indicator associated with high blood pressure10,11, metabolic syndrome12-14, insulin resistance and triglycerides11, type 2 diabetes9,12,14,15, cardiovascular risk factors15,16, and visceral fat12,13,17. This marker has been measured in children and adolescents10,18, adults12,15,16, and older adults13.

Within this context, it is important to compare NC with other anthropometric measurements and to establish cut-off points for physically active Brazilian older women, considering that this anthropometric parameter provides consistent results regarding the accumulation of upper body subcutaneous fat9,17. Moreover, NC can be used in clinical practice and in epidemiological studies as a simple, reliable, rapid, low-cost indicator, which is correlated with other commonly used anthropometric parameters9,17. However, studies applying this method to physically active older adults are sparse, especially in Brazil11,12,19, and no reference parameters are available for this population.

In view of these considerations, the objective of the present study was to evaluate NC as a discriminator of overweight and obesity and to establish cut-off points for older women enrolled in a physical activity program.


Study design, population and sample

This was a cross-sectional, descriptive, correlation study. The population consisted of about 300 older adults participating in the extension program of the Senior Study Group (GETI in the Portuguese acronym) conducted at the Center of Health and Sports Sciences (CEFID) of the State University of Santa Catarina (UDESC).

Non-probability sampling was used for selection of the sample. The following inclusion criteria were adopted: age of 60 years or older, participation in the test battery offered by GETI in March 2016, and female gender. The gender choice was due to the large participation of women in this type of intervention20. Older women who were unable to perform the anthropometric tests were excluded. Thus, the final sample consisted of 170 older women.

Instruments and data collection procedures

Anamnesis interviews were held for characterization of the participants to obtain sociodemographic data and health conditions. The data were collected in the first week of March 2016.

Body weight, height and circumferences (waist and neck) were measured with a Plenna Wind® digital scale (MEA 07710), WCS® stadiometer (217 cm) and CESCORF® anthropometric tape measure, respectively. The variables were measured in the following order: body weight, height, WC, and NC. One evaluator obtained the body weight, height and WC measurements and another performed the NC measurements. Both evaluators were trained in the data collection by an instructor certified by the International Society for the Advancement in Kinanthropometry (ISAK) Level 3.

Body weight (in kg) was measured with the participant standing barefoot and wearing only light clothing. For the measurement of height, the participant was placed standing barefoot, feet parallel to each other, with the posterior region of the heels, pelvic girdle, shoulder girdle and occipital region against the stadiometer and the head in the Frankfurt plane. At the end of an inspiration, the cursor was positioned at an angle of 90° to the scale, touching the highest point of the participant’s skull, and the measurement was obtained in meters (m). Body weight and height were measurement once.

Waist circumference was measured at the narrowest point between the umbilical scar and iliac crest. For the measurement, the participant was placed standing with the arms crossed over the chest. The evaluator was positioned in front of the subject and the measurement was obtained at the end of a normal expiration. The neck circumference, as well as the other measurements, were performed according to the protocol proposed by ISAK21. For this purpose, the participant assumed a relaxed sitting position, with the arms hanging freely at the side and the head positioned in the Frankfurt plane. The circumference of the neck (in cm) was measured immediately above the thyroid cartilage. Two measurements of WC and NC were obtained.

After collection of the anthropometric measurements, the BMI was calculated as the body weight (kg) divided by the square of height (m). The cut-off values recommended by the World Health Organization were used for the classification of BMI and WC (2, 22). For BMI, a value < 18.5 kg/m2 was classified as low weight, 18.5 to 24.9 kg/m2 as normal weight, 25.0 to 29.9 kg/m2 as overweight, and > 30 kg/m2 as obesity (2). For WC, a value < 79.9 cm was classified as normal, 80 to 88 cm as moderate risk, and > 88 cm as high risk22.

Ethical aspects

The study was approved by the Ethics Committee of UDESC (Protocol 052406/2015). All participants received detailed information about the objective of the study and signed the free informed consent form.

Data analysis

Descriptive statistics and correlation analysis were used. The intraobserver technical error of measurement was calculated for NC23. Normality of the data was verified using the Kolmogorov-Smirnov test. For analysis of the correlation between NC, BMI and WC, Pearson’s test was used for parametric data and Spearman’s test for nonparametric data. Bland-Altman plots were constructed to evaluate the limits of agreement between NC, BMI and WC. For this analysis, Z-scores were calculated for NC, BMI and WC to remove the unit of measurement.

Receiver operating characteristic (ROC) curves were constructed to determine the sensitivity and specificity of NC in relation to BMI and WC, identifying the total area under the curve and the 95% confidence interval. In addition, cut-off points were established according to the best sensitivity and specificity for NC in relation to BMI and WC.

All analyses were performed using the SPSS® 20.0 program, except for the cut-off points suggested by the ROC curve which were obtained with the MedCalc® program. A level of significance of 5% was adopted in all analyses.


The participants in the study had a mean age of 69.5 (SD = 6.8) years. With respect to sociodemographic characteristics, 40.6% (n = 69) of the women were married and 32.5% (n = 55) had completed high school. Most older women had a good perception of their health status (54.9%; n = 93) and had some disease (81.8%; n = 137). The most frequent diseases were arterial hypertension (43.9%; n = 74), arthrosis (20.1%; n = 34), and diabetes (17.7%; n = 30). Analysis of risk behaviors showed that 98.8% (n = 168) of the participants did not smoke. In addition to the activities offered by the university program, 51.5% (n = 87) of the older women performed other physical activities.

Table 1 shows the descriptive values of body weight, height, BMI, WC, and NC. Calculation of the intraobserver technical error of measurement for NC revealed an absolute error of 0.58 and a relative error of 1.65%. For WC, the absolute error was 3.9 and the relative error of 0.8%.

According to the BMI cut-off points, 15.4% of the participants were classified as normal weight, 39.6% as overweight, and 43.2% as obese. Only 1.8% of the women were low weight. With respect to WC, 14.8% of the women were classified as normal, 20.7% as moderate risk, and 64.5% as high risk.

Spearman’s test revealed a significant correlation between BMI and NC (rho = 0.656; p < 0.0001) (Figure 1A). An r value of 0.561 was obtained for the correlation between NC and WC (p < 0.0001) (Figure 1C).

An area under the ROC curve of 0.819 was obtained for NC in relation to BMI for women classified as overweight. The most adequate NC cut-off point was 33.07 cm. Using this cut-off, NC was able to predict a normal BMI in 86.2% of the women and overweight in 64.2% (Table 2). The area under the ROC for NC in relation to BMI for women classified as obese was 0.902. The most adequate NC cut-off point was 34.05 cm. Using this cut-off, NC was able to predict a normal BMI in 93.1% of the women and obesity in 82.4% (Table 2).

&Adequate value of NC to discriminate BMI (overweight/obesity) and WC (moderate risk/high risk).


The area under the ROC curve for NC in relation to WC was 0.711 for women classified as moderate risk. A cut-off point of NC of 32.15 cm was the most adequate in terms of sensitivity and specificity. Using this cut-off, NC was able to predict normal WC in 56.0% of the women and a moderate risk in 82.9% (Table 2). For women classified as high risk, the area under the ROC curve for NC in relation to WC was 0.864. The most adequate NC cut-off was 34.15 cm. Using this cut-off, NC was able to discriminate normal WC in 88.0% of the women and a high risk in 72.7% (Table 2).


An important finding of the present study was that NC was significantly correlated with the anthropometric measurements BMI and WC. In addition, the NC cut-off points to discriminate obesity and a high risk of abnormal body fat distribution showed a sensitivity and specificity higher than 70%, characterizing an adequate capacity to detect body fat distribution in different groups (obese vs non-obese; high risk vs no risk).

High prevalences of overweight and obesity (82.8%) classified based on BMI and of WC values above the recommended levels (85.2%) were observed. Similar values for BMI have been reported in a national study conducted in Brazilian capitals24 and for WC in a study involving women from the southeastern region of Brazil25.

Although the mechanism underlying the relationship between NC and the occurrence of metabolic problems is not well understood13, this measurement has been suggested as an alternative and innovative approach12 and is used as a simple, rapid26 and reliable method9 for the identification of obesity. Joshipura et al.27, studying 1,206 older adults aged 40 to 65 years, found a correlation of NC with BMI of r=0.66 and with WC of r=0.64. Yan et al.13 reported correlations of NC with BMI and WC of r=0.70 and r=0.72, respectively, in 1,121 Chinese older women. These values are significant and similar to those obtained in this study, demonstrating the relationship between anthropometric methods and highlighting the relevance of this measurement even when used in populations with different characteristics.

This study suggested cut-off points based on the sensitivity and specificity values derived from the ROC curve. Regarding BMI, an NC ≥ 33.07 cm can discriminate overweight and a value ≥ 34.05 cm can predict obesity. Higher NC cut-off points have been reported by Ben-Noun, Sohar, Laor26 who studied 519 middle-aged Israeli women and found values ≥ 34.0 and ≥ 36.5 cm to discriminate overweight and obesity, respectively. Yan et al.13 also reported higher NC values in relation to BMI for 1,121 Chinese older women. In that study, an NC ≥ 35 cm discriminated a higher risk of metabolic syndrome and obesity in older women.

With respect to WC, despite the observation of lower sensitivity and specificity compared to the correlation between NC and BMI, a good area under the curve was obtained, with an NC ≥ 32.15 cm discriminating a moderate risk and ≥ 34.15 a high cardiovascular risk. The more accurate predictive capacity of NC in relation to BMI compared to WC might be explained by the fact that BMI is a measure of body proportionality, while WC is measured at a specific site to verify body fat distribution.

Comparing NC and WC, a study involving 153 obese women aged 40 to70 years established a cut-off point of NC ≥ 35 cm using binary logistic regression14. Moreover, the authors concluded that, in individuals with severe obesity,NC has a better performance than WC for the evaluation of metabolic health14.

As mentioned earlier, the cut-off points of NC differed between studies. This variation might be due to differences in the characteristics of the samples such as age group and ethnic background, as well as differences in the measurement techniques of NC. Our study included older women (> 60 years) who performed physical activity. In addition, NC was measured according to the protocol proposed by ISAK, which establishes its measurement immediately above the thyroid cartilage. This technique was chosen because it uses an international protocol that has standardized anthropometric techniques28. However, other sites of measurement such as 0.1 cm below the thyroid cartilage27 and at the level of the thyroid cartilage18have been reported.

Finally, although BMI and WC are relatively low-cost and simple methods that require little equipment, NC can be used as another indicator of obesity both in clinical practice and in epidemiological studies9. Neck circumference is a good option when professionals do not have a scale and stadiometer or private room for the measurement of body weight, height and WC where the individual needs to undress. It may also be an alternative in places and on days of low temperatures since the measurement site is easily accessible and normally not impeded by clothing.

Considering the comparison of NC with BMI and WC and the cut-off points established, a value ≥ 34 cm was found to indicate disturbances and body fat distribution in physically active older women. However, caution is needed when the cut-offs established in this study are used since they were based on doubly indirect measures, BMI and WC. It is important that the population evaluated is similar and that the measurement technique is accurate, taking into consideration inter- and intraobserver technical errors of measurement.

The use of NC combined with BMI, WC and body composition tests is recommended. Further studies are needed that involve larger samples, age stratification, inclusion of men, and validation of this measure using gold standards such as dual-energy x-ray absorptiometry or hydrostatic weighing. In addition, we suggest the establishment of cut-off points of NC to discriminate cardiovascular and metabolic diseases in physically active older women, as well as comparison with the predictive capacity of BMI and WC.


Neck circumference is a good discriminator of overweight, obesity and body fat distribution in physically active older women when compared to BMI and WC. A cut-off point of 34 cm was established as an indicator of obesity and high risk of abnormal body fat distribution.
