Objective: To explore the relationship between the occurrence of sub-health and health promotion lifestyle in Guangdong province to provide epidemiological evidences for prevention of sub-health.
Methods: A 1:1 nested case-control study was carried out involving 133 cases from the cohort study paired with 133 control case matched for gender and age.
Results: The univariate conditional logistic regression model showed no significant association of marital status, education level, or body mass index with the occurrence of sub-health, but a significant correlation was found between lifestyle and sub-health with an odd ratio of 5.90 (95% CI: 3.12-11.16, P=0.000). Analysis of the multivariate conditional logistic regression model on the 6 subscales of health promotion lifestyle showed that stress management was significantly correlated with the occurrence of sub-health with an odd ratio of 4.00 (95% CI: 1.54-10.40, P=0.004).
Conclusion: A unhealthy lifestyle, especially in terms of stress management, is the major risk factor contributing to the occurrence of sub-health.
