Comparison of pain perception in young adult males with normal and increased BMI
Shruti Sharma, Garima Charak

Background: The sensation of pain is a universal phenomenon and is an indication of disease or tissue damage. The intensity with which pain is perceived by an individual varies widely, being influenced by the nature of the noxious stimulus, as well as by genetic, racial, cultural, and socioeconomic factors. Obesity is associated with disability in adults with chronic pain, such that individuals in overweight and obese weight categories report more inactivity, higher levels of depression, lower physical health-related quality of life, and are more likely to be completely disabled than those in a normal weight category. Aim of the study: To compare pain perception in young adult males with normal and increased BMI. Materials and methods: The present study was conducted in the Department of Anesthesiology of the Medical institutions. The ethical clearance for the study was approved from the ethical committee of the hospital. A total of 100 volunteers were selected for the study which consisted of underweight, normal weight, overweight and obese young adults with age ranging between 12 to 25 years. The subjects were grouped based on their body weights. The subjects completed questionnaires stating their age, sex, education level, health condition and drugs used (if any), as well as exercise performance and frequency, followed by a brief interview. Pressure pain was conducted first, followed by a 10-minute rest period before conduction of cold-pressor pain procedures in separate session, to avoid carry-over effect. Results: A total of 100 subjects were enrolled in the study. There were 52 males and 48 females in the study population. Based on BMI of the subjects, 22 subjects were underweight, 25 subjects were normal weight, 29 subjects were overweight and 24 were obese. We observed that threshold for cold pressor pain shows BMI dependent variation, with underweight subjects having highest threshold (less pain) and obese subjects having lowest threshold (higher pain) (Figure 2), but cold pressor pain tolerance do not show statistically significant variation, though underweight subjects had the lowest tolerance among the test groups. Conclusion: Within the limitations of the present study, it can be concluded that high BMI is related to decreased pain threshold among young population. Obese subjects in this study were found to have a significantly lower cold pressor pain threshold than underweight subjects, but no difference on cold pressor pain tolerance.
