BackgroundNeck circumference (NC) was proposed as promising marker to assess body fat distribution and cardiometabolic risk.ObjectivesWe
aimed to assess associations of NC with anthropometric traits,
cardiometabolic risk markers and self-reported cardiometabolic diseases.MethodsNC
was measured in a subsample (5,865 participants) of the German National
Cohort (NAKO Gesundheitsstudie, NAKO), study region Kiel. Linear and
logistic regression models were applied to assess associations of NC
with anthropometric and cardiometabolic risk markers and self-reported
cardiometabolic diseases, including diabetes, heart failure, gout, and a
composite endpoint ‘clinical CVD’ (combining history of angina
pectoris, stroke, myocardial infarction, and peripheral artery disease).
Models were adjusted for sex and age, cardiovascular risk factors
(systolic blood pressure, diabetes, LDL-cholesterol, use of
lipid-lowering and antihypertensive medication, smoking status), and
BMI.ResultsMean
NC values (± SD) were 39.5±3.0 in men and 33.6±2.7 cm in women. NC was
positively associated with anthropometric traits, visceral adipose
tissue [cm] (β=1.45 [95% confidence interval 0.88; 2.02]), systolic
(β=0.37 [0.19; 0.56]) and diastolic (β=0.17 [0.05; 0.29]) blood
pressure, HbA1c (β=0.02 [0.01; 0.02]), non-fasting glucose (β=0.57
[0.31; 0.83]), and inversely associated with HDL-cholesterol (β=-0.73
[-0.91; -0.54]). Furthermore, NC showed associations with diabetes
(OR=1.08 [1.02; 1.15]), heart failure (OR=1.12 [1.02; 1.23]) and gout
(OR=1.09 [1.01; 1.17]). Association with ‘clinical CVD’ did not remain
statistically significant after BMI adjustment.ConclusionsNC
was associated with several cardiometabolic risk factors, including
glycemic and lipid traits and self-reported cardiometabolic diseases.
These observations suggest that NC may be a useful surrogate marker for
cardiometabolic risk.
