Summary
High body mass index (BMI) is linked to meralgia paresthetica (MP). Obesity significantly increases the risk of developing MP, suggesting a connection to abdominal pressure.
Area of Science:
- Neurology
- Dermatology
- Public Health
Background:
- Meralgia paresthetica (MP) is a condition characterized by nerve pain.
- The relationship between body mass index (BMI) and MP requires further investigation.
Purpose of the Study:
- To investigate the association between body mass index (BMI) and the occurrence of meralgia paresthetica (MP).
Main Methods:
- A case-control study involving 104 MP cases and 416 controls (neurological and dermatological).
- Cases and controls were matched for age and sex.
- Statistical analyses included Wilcoxon and chi-squared tests, with calculation of odds ratios (OR(MK)) and 95% confidence intervals (CI).
Main Results:
- Mean BMI was significantly higher in MP cases (28.0 +/- 4.9) compared to neurological (26.0 +/- 4.3) and dermatological controls (25.5 +/- 3.9).
- Significant associations were found between BMI categories and MP.
- Obesity (BMI >= 30) demonstrated a doubled risk of MP (OR(MK) 2.04-2.5).
Conclusions:
- Elevated BMI is significantly associated with meralgia paresthetica.
- Obesity doubles the risk of developing MP.
- Increased intra-abdominal pressure due to high BMI may contribute to MP.
