Healthy lifestyle associated with dynamic progression of type 2 diabetes: A multi-state analysis of a prospective cohort.

BACKGROUND

Although the association of a healthy lifestyle with type 2 diabetes (T2D) has been extensively studied, its impact on the dynamic trajectory, including progression, onset and prognosis, of T2D has not been investigated.

METHODS

Using data from the UK Biobank, 461 168 participants without diabetes or diabetes-related events were included. We incorporated four lifestyle factors to construct the healthy lifestyle score (HLS). We employed a multi-state model to examine the relationship between a healthy lifestyle and transition in T2D progression, including transitions from baseline to diabetes, complications, and further to death. The cumulative probability of above transitions based on the health lifestyle score was calculated.

RESULTS

The results indicated that adhering to 3-4 healthy lifestyles had an inverse association with the risk of transition from baseline to diabetes (hazard ratio (HR) = 0.966; 95% confidence interval (CI) = 0.935-0.998, P = 0.038), diabetes to complications (HR = 0.869; 95% CI = 0.818-0.923, P = 5.2 × 10), baseline to death (HR = 0.528; 95% CI = 0.502-0.553, P < 2 × 10, and diabetes to death (HR = 0.765; 95% CI = 0.591-0.990, P = 0.041) compared with maintaining 0-1 healthy lifestyles. In addition, the transition probability of the above transitions can be lower with maintaining 3-4 healthy lifestyles.

CONCLUSIONS

Healthy lifestyles are negatively associated with the risk of multiple outcomes during the dynamic progression of T2D. Adherence to 3-4 healthy lifestyle behaviours before diabetes onset can lower the risk of developing T2D, further reducing the risk of diabetes complications and death in patients with T2D.
