Outline
To explore the change trajectories of estimated cardiorespiratory fitness(eCRF) among middle-aged and older adults in China based on data from the China Health and Retirement Longitudinal Study(CHARLS) and to analyze the relationship betweent different classification of the trajectories and the risk of cardiovascular disease.
Data from 4 172 middle-aged and older adults who completed follow-up in CHARLS from 2011 to 2020 were included.eCRF levels in 2011,2013,and 2015 were calculated using non-exercise equations.Group-based trajectory modeling was employed to identify the classification of the eCRF change trajectories.Logistic regression was used to analyze the relationship between the classification of the eCRF change trajectories and the risk of cardiovascular disease,followed by subgroup analyses.
Among the 4 172 participants,1 150 developed cardiovascular disease,yielding an incidence rate of 27.6%.Three distinct eCRF change trajectories were identified,namely low-increasing then decreasing group(7.5%),moderate-rapidly decreasing group(28.0%),and high-slowly decreasing group(64.5%).After adjusting for multiple variables,Logistic regression showed that compared with the high-slowly decreasing group,both the low-increasing then decreasing group(OR=1.90,95%CI 1.43-2.51) and the moderate-rapidly decreasing group(OR=1.42,95%CI 1.20-1.69) had a higher risk of cardiovascular disease.Subgroup analyses revealed an interaction between the classification of the eCRF change trajectories and hypertension(P=0.008).
Group heterogeneity exists in eCRF change trajectories among middle-aged and older adults in China.Those with higher eCRF levels tend to have a lower risk of cardiovascular disease.Hypertensive status may influence the relative strength of the association between the classification of the eCRF change trajectories and the risk of cardiovascular disease.
