Neck Circumference and Cardio-Metabolic Syndrome

Abstract

Background: Only few studies about neck circumference (NC) as a measure of cardio metabolic syndrome available from India. Study was conducted to establish an association between neck circumference and cardio metabolic syndrome. Material and Methods:Cross-sectional study was conducted in a tertiary care hospital in South India. NCEP: ATPIII 2001 guideline was used for diagnosis of Cardio-metabolic syndrome among subjects. Neck circumference was measured and it was correlated with Cardio-metabolic syndrome.Results: Mean neck circumference was found to be 36.5 cms. Cardio-metabolic syndrome was present in 272 participants, of which 100 were females and 172 males. Among females 82(82%) had neck circumference >34cms, 18(18%) had <34cms and among males 117(68%)had NC >37cms and 55(32%) had NC<37cms. All individual parameter of cardio metabolic risk factor, i.e., BMI, waist circumference, hip circumference, systolic blood pressure, diastolic blood pressure, FBS, HDL & TG except waist/hip ratio were correlating with abnormal neck circumference when compared with those with normal neck circumference. Conclusion:Neck circumference with metabolic syndrome correlated better among females than males. Men with NC >37 cm and women with NC >34 cm are more prone for cardio metabolic syndrome and require additional evaluation. Measurement of NC is a simple, time saving, and least invasive measurement tool.

Positive association of neck circumference and cardio-metabolic risk factors in Ekiti, Nigeria

“…The differences are not unexpected given the relationship between NC with age, BMI and WC. Consistent with previous studies men had a higher mean NC [14,18,21].…”

“…A study conducted among the Turks [11,13] and Saudi Arabs [14] revealed that NC had positive correlation with indices of general and central obesity. Similar studies among the Chinese [15][16][17], Indians [18,19], Indonesians [20], and other Asian populations [21], also confirmed the positive association between NC with established anthropometric indices and cardiovascular risk factors. Specifically, Fan et al, [22] examined the relationship between NC and arterial hypertension, and found that NC predicted blood pressure, independent of other anthropometric indices.…”

“…In the Framingham Heart study, Preis et al [10] found that NC was positively associated with SBP and DBP only in men, after adjustment for visceral adipose tissue (VAT) and BMI. Some workers also found varied relationship between NC and cardiometabolic risk factors in the men and women [18]. However, Zhou et al [15] and Fan et al [22] found that NC predicted hypertension in both men and women.…”

“…Some workers evaluated the predictive ability of NC for obesity and insulin resistance, and found that the mean NC of participants with overweight/general obesity was higher than those with normal weight [17]. Kumar et al [18] examined the relationship between NC and metabolic syndrome among Indians, and found that compared with those without the syndrome, more people with metabolic syndrome had abnormal NC. Other workers also reported a higher mean NC in people with metabolic syndrome [25].…”

“…Similarly, NC with metabolic syndrome correlated better among females than males. The cross-sectional study was conducted in a tertiary care hospital in South India, showed that men with NC >37 cm and women with NC >34 cm are more prone to cardiometabolic syndrome and require additional evaluation [ 10 ]. A study of 3182 diabetic Chinese patients showed that NC correlated positively with BMI, WC, and metabolic syndrome [ 11 ].…”
