Data relating to seven health metrics and plasma hs-CRP levels were collected at baseline and the end of follow-up. The change in health metrics of each individual was compared and recorded. The potential association of gain or loss of each health metric, as well as the change in the total number of health metrics that each individual had during follow-up, with the risk of increased hs-CRP level, were explored by multiple Cox proportional hazards models.Results: A total of 72,321 participants (94.51%) completed the follow-up, and the average follow-up time was 4.1 years. Ideal body mass index (BMI), physical activity, smoking status and total cholesterol all had significant impacts on hs-CRP levels, with ideal BMI having the largest impact. Losing ideal BMI during follow-up raised the probability of hs-CRP increase during the follow-up time by 1.72 (95% CI, 1.59– 1.86) times for men and 2.05 (95% CI, 1.76– 2.39) times for women. The effects of ideal salt intake and blood pressure on hs-CRP levels were uncertain. Changes in the total number of ideal metrics for each individual had a significant cumulative effect on hs-CRP. The hazard ratio of loss of four to six health metrics during follow-up on the risk of hs-CRP increase was 1.69 (95% CI, 1.38– 2.06) for men and 1.52 (95% CI, 1.13– 2.04) for women.Conclusion: Loss or gain of ideal cardiovascular health metrics is associated with significant fluctuations in plasma hs-CRP levels. The cardiovascular benefits brought by the ideal health metrics are mediated at least in part by reducing systemic inflammation in the body.Keywords: ideal cardiovascular health metrics, highly sensitive C-reactive protein, cardiovascular diseases
