IJCM_270A: Neck circumference as a potential predictor of blood pressure: An exploratory Case Control Study

Abstract

Background: Hypertension (HTN) poses a substantial health challenge globally, affecting nearly one billion people. Due to its silent nature, early detection is crucial to prevent end-organ damage. Recent studies suggest a correlation between hypertension and upper body subcutaneous fat accumulation, particularly in the neck circumference (NC). This anthropometric measure is proposed as practical surrogate for assessing visceral obesity, surpassing traditional measures like waist circumference. Objectives: To correlate Neck Circumference (NC) with blood pressure in adults and to correlate other risk factors of HTN with NC. Methodology: This Case Control Study was conducted at Government Wenlock Hospital, KMC Attavar, and KMC outreach clinics. The study population included hypertensive cases and non-hypertensive controls, with a sample size of 110 in each group. Participants above 25 years of age were included, and those with specific conditions were excluded. Mercury Sphygmomanometer, Stethoscope, Flexible measuring tape, and Weighing scale were used as study instruments. Results: Overall, 79.5% of individuals with NC > median consumed a non- vegetarian diet, and those with high salt intake were 1.42 times more likely to develop HTN. Although not statistically significant, 53% of those with a high cholesterol diet had NC greater than median. The study emphasizes the need for larger sample sizes for more conclusive results. Conclusion: The study establishes a positive correlation between blood pressure and NC, proposing NC as a practical and socially acceptable anthropometric marker. The non-invasive nature and simplicity of NC measurement make it a feasible tool for routine assessment, potentially impacting hypertension guidelines.
