Can Neck Circumference Predict Metabolic Syndrome? An Experience From A University Community

Predictors of Metabolic Syndrome in the Elderly: A Review

“…NC was also evaluated, with similar cut-off points suggested by the authors, 8,19,20 which can be explained by the fact that this measurement is little affected by agingrelated changes in body composition. The association between NC and MetS may be related to the fact that subcutaneous fat in the neck area is responsible for higher systemic release of free fatty acids.…”

“…The cut-off points for women were similar between white and black women, although the cut-off point for black women did not predict MetS, in contrast to what was observed for men. Limpawattana et al 19 Oliveira and Yan et al 8 presented similar cut-off points for NC to predict MetS in individuals aged over 50 and 65 respectively, and Limpawattana et al 19 showed an efficiency over 72% for the cut-off point suggested for men (sens: 70.89%; spec: 81.15%) and women (sens: 86.54%; spec: 59.39%).…”

“…The association between NC and MetS may be related to the fact that subcutaneous fat in the neck area is responsible for higher systemic release of free fatty acids. 19 This excess of free fatty acids is associated with resistance to insulin, hypertriglyceridemia, vascular lesion and high blood pressure, and could predict MetS.…”

“…However, a limitation of this study was that the authors considered individuals aged between 46 and 65 as the elderly group and, for this reason, their results cannot be extrapolated to individuals aged over 65. Altogether, the studies 8,[18][19][20] suggested the use of NC, as it is a simple and practical anthropometric parameter, able to identify MetS. Another advantage of the NC is the fact that it is not affected during respiratory movement or in the postprandial period.…”

“…In the studies 8,19,20 which evaluated the predictive capacity of the NC, the cut-off points suggested by the authors were quite similar, varying between 35 and 41 cm for men and 33 and 35 cm for women (Table 2). Hoebel et al 20 observed that white men presented a higher cut-off point (41 cm) when compared to black men (35 cm).…”
