Abstract
Context:
Interindividual variability in pain is modified by interactions of multiple biopsychosocial factors. Though there are reported findings on pain variability from studies around the world, the relationship between pain outcomes and anthropometric profiles remains unclear due to conflicting findings.
Aim:
This study was designed to investigate relationships between experimental pain outcomes and anthropometric profiles in a healthy Nigerian population.
Materials and Methods:
One hundred and sixty-one healthy volunteers aged 20 to 65 years were recruited for the study. Experimental pain was induced using cold pressor pain, pressure pain, and ischemic pain procedures.
Results:
We found that subjects with a normal body mass index (BMI) had a statistically significant higher ischemic pain tolerance than their obese counterparts. Right-handed participants had higher cold pressor pain thresholds than their left-handed counterparts, and the difference was statistically significant. Hb genotype and blood groups affected experimental pain outcomes. There was a statistically significant negative correlation between BMI and ischemic pain tolerance.
Conclusion:
We concluded that the association between BMI and experimental pain outcomes depends on the type of pain induction method used. Right-handedness appeared to be associated with increased cold pressor pain threshold.
