Relationship between anthropometric parameters, neck circumference, and intraocular pressure among normal adults in Ile-Ife

Abstract

Aim: To determine the relationship between anthropometric parameters, neck circumference (NC), and intraocular pressure (IOP) among the
adult population in Ile-Ife, Nigeria

Method: A descriptive cross-sectional study was conducted among 450 randomly selected nonglaucoma subjects from the students and staff  population of Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria. Ethical clearance for the study was obtained from the  institution and written informed consent was obtained from subjects. The demographic profile of subjects was documented and measurements of  anthropometric parameters, NC, and IOP were carried out. Data were analyzed using statistical software SPSS 23.0. The bivariate linear regression  model was used for correlation analysis and the level of statistical significance was set at P<0.05.

Results: Four hundred and fifty subjects were examined comprising 194 males (43.1%) and 256 females (56.9%). The mean age was 34.26 ± 11.78  years. The mean values for height, weight, body mass index (BMI), and NC were 1.67 ± 0.09 m, 70.7 ± 14 kg, 25.49 ± 4.91 kg/m², and 34.65 ± 2.79  cm, respectively. The weight and height were significantly higher in males than in females but BMI was higher in females. The mean IOP for all the  subjects was 14.40 ± 3.26 mmHg. Weight, BMI, and IOP significantly increased with age, and mean IOP also significantly increased with increasing height (P= 0.045), weight (P=0.005), NC (P=0.0005), and BMI (P=0.0001).

Conclusion: Increased weight, BMI, and NC were found to be significantly associated with IOP elevation, which is a risk factor for glaucoma
