Correlation of hallux deviation angle with age, weight, height, and body mass index in adult Nigerians

Abstract

CONTEXT: Hallux deviation angle (HDA) is the angle between the axis of the hallux and axis of the first metatarsal bone.
AIMS: The aim was to determine whether there is any correlation between HDA and age, weight, height, and body mass index (BMI) in an adult Nigerian population.
SETTING AND DESIGN: This was a cross‑sectional study.
MATERIALS AND METHODS: A total of 1033 individuals consisting of 548 males and 485 females were studied. Age range was 15–74 years. HDA was measured by the goniometric method.
STATISTICAL ANALYSIS USED: Analysis was done using Statistical Package for the Social Sciences version 21. Correlation of HDA with age, weight, height, and BMI was done using Pearson’s correlation. Test of significance was done using Chi‑square.
RESULTS: Mean age in years was 34.1 (±13.4) for males and 29.6 (±12.0) for females. Mean BMI in kg/m² was 25.8 (±7.5) for males and 26.1 (±5.5) for females. The mean HDA in degrees on the right and left feet, respectively, were 5 ± 6 and 7 ± 7 for males and 5 ± 6 and 6 ± 6 for females. In males, there was a positive but weak correlation of HDA with age on both feet. There was also weak correlation of HDA with BMI on the right feet, but there was no correlation of HDA with weight and height. In females, there was positive and weak correlation of HDA with height on both feet while but there was no correlation with age, weight, or BMI.
CONCLUSION: HDA did not correlate with age, weight, height and BMI in our environment.
