Background: Systemic low-grade inflammation (SLGI), as assessed by measurements of high-sensitivity C-reactive protein (hs-CRP), is a strong independent risk factor for cardiovascular diseases (CVD). Although individuals with hs-CRP ≤ 1 mg/L have been defined as being at low risk according to AHA/CDC guidelines, the value of very low hs-CRP levels (<0.5 mg/L) for public health practices is unclear.
Methods: This cross-sectional cohort study assessed 104 healthy Koreans aged 34?60 years. Their anthropometric indices, results of computed tomography and bioelectrical impedance analysis, and biomarker concentrations in fasting venous blood samples were evaluated.
Results: Of 104 subjects, 88 (84.6%) had hs-CRP concentrations ≤ 1.0 mg/L. When this low risk group was subdivided into subjects with hs-CRP <0.5 mg/L and hs-CRP levels between 0.5 and 1 mg/L, the former group showed better anthropometric profiles for central obesity and lipidemia.
Conclusion: Even in low risk subjects, higher serum concentrations of hs-CRP may be associated with increased central obesity. Lifestyle modifications to lower hs-CRP should be recommended in public health practice, with hs-CRP viewed not as a risk marker, but rather as a marker of wellness.
