Objective:
Chronic inflammation and oxidative stress are associated with lifestyle-related diseases. Research into the pathophysiology of lifestyle-related diseases is important for Mongolian people. Our study investigated the correlation among the d-ROMs test (a measure of the total oxidant capacity of blood), serum amyloid A (SAA) and high-sensitivity C-reactive protein (hs-CRP) levels in a young Mongolian population.
Methods:
The data, including anthropometric and biochemical markers, were collected from 78 Mongolian volunteers (male/female = 27/ 51, mean age 21 years). The correlation between the SAA and d-ROMs levels was examined, as well as the correlation between the hs-CRP and d-ROMs levels.
Results:
The SAA levels were 3.2 microg/mL (median), hs-CRP .04 mg/dL (median) and d-ROMs 309 CARR U, respectively. There was a significant and positive correlation between the SAA and d-ROMs levels (r=.40, P<.01), in addition to a significant and positive correlation between the hs-CRP and d-ROMs levels (r = .32, P < .01). These significant correlations remained independent in a multiple linear regression analysis. A subgroup analysis by sex revealed the positive correlation between the SAA and d-ROMs levels to be greater, relative to that between the hs-CRP and d-ROMs levels, particularly in the female group.
Conclusions:
The coexistence of chronic inflammation and oxidative stress can be present even in young Mongolian people, suggesting that their coexistence may be a target of early prevention of lifestyle-related diseases. In addition, not only hs-CRP, but also SAA can be used to evaluate the relationship of oxidative stress in this population. Further studies are necessary to confirm the observed relationship.
