Introduction:

usCRP is an inflammatory biomarker produced in the liver. Obesity has been associated with a chronic inflammatory process and linked with said biomarker by overexpressing pro-inflammatory cytokines produced in adipose tissue.

Objectives:

study the association between elevated usCRP as a pro-inflammatory marker in patients with a diagnosis of obesity in the Mexican population.

Material and methods:

retrospective and cross-sectional study; registries of usCRP in patients of the preventive medicine clinic in a private hospital in Mexico City were reviewed from January to June 2019. The population included 672 patients, of which 419 were male and 253 female at least 20 years of age, in whom usCRP values < 10 mg/L. We performed a multiple linear regression with logarithmic transformations of usCRP, BMI, and sex.

Results:

the coefficient for the natural logarithm for the BMI was positive and statistically significant (p < 0.001), the coefficient for the male sex turned a negative and statistically significant result (p < 0.001), and the model obtained an R(2) = 0.17.

Conclusions:

a positive association between elevated usCRP, female sex, and BMI were found; however, this model does not manage to explain all elevations in usCRP, meaning that we found elevations in both groups. More significant elevations were found in obese patients, with or without comorbidities, thus suggesting that usCRP is an inflammatory marker associated with obesity in Mexican population.
