Relationships between the neck circumference and cardiovascular risk factors of middle-aged and elder people in community / 中华内分泌代谢杂志

ABSTRACT

Objective To investigate the relationships between the neck circumference and cardiovascular risk factors of middle-aged and elder people in a community. Methods Altogether 9 665 community residents ( age≥40 years) were enrolled in the present study. The height, weight, neck circumference, waist circumference, blood pressure, total cholesterol, triglycerides, low density lipoprotein-cholesterol ( LDL-C ) , high density lipoprotein-cholesterol ( HDL-C) , blood glucose, glycosylated hemoglobin, and fasting insulin were measured, and documented in the questionnaire along with other basic information. After adjusted for age, Pearson correlation coefficient was used to analyze the relationship between the neck circumference and the binary variables of cardiovascular risk factors. SPSS16.0softwarewasusedforstatisticalanalysis. Results (1)Theneckcircumferenceswere(37.11±2.79)cm in male and (32. 79 ± 2. 31) cm in female;which were higher in males than females. In both males and females, after adjusted for age, the neck circumference was positively correlated to waist circumference, body mass index, blood pressure, plasma glucose, LDL-C, triglycerides, and insulin resistance, the neck circumference was negatively correlated to HDL-C(all P0. 05). (2) After adjusted for body mass index and the waist circumference, the neck circumference of males increased with the risk of diabetes ( OR=1. 14, 95% CI 1. 02-1. 28);while the higher neck circumference of females increased the risk of hypertension (OR=1.17,95% CI1.08-1.27),diabetes(OR=1.24,95% CI1.13-1.37),dyslipidemia(OR=1.17,95%CI 1.09-1.27),andinsulinresistance(OR=1.15,95% CI1.06-1.26). Theneckcircumferenceexertedhigher impact on women than it did on men. Conclusion The neck circumference is associated with the cardiovascular risk factors. This association in females is stronger than that in males. The neck circumference seems to be an independent indicator for the cardiovascular risk.
