Clinical Report: Assessing the Effects of the Traditional Chinese Spring Festival on Glycemic Management

Overview

This study quantifies the association of the Chinese Spring Festival with HbA1c levels in a large hospital cohort, revealing a statistically significant increase in median HbA1c during the festival period.

Background

Diabetes mellitus presents a significant public health challenge in China, with HbA1c serving as a critical marker for long-term glycemic control. The Spring Festival, a major cultural holiday, is associated with lifestyle changes that may disrupt glycemic management.

Data Highlights

Key Findings

• The median HbA1c during the lagged Spring Festival week was significantly higher than in the control period (6.1% vs. 6.0%; median difference +0.1%, P<0.001).
• The effect was most pronounced with a 60-day lag, attenuated at 30 days, and absent at 90 days.
• Subgroup analysis indicated the increase was concentrated in patients under diabetes core management (Festival week: 6.2% vs. control: 6.1%, P<0.05).
• No significant effect was observed in the general health screening population (P = 0.45).
• Quantile regression confirmed an independent association (β=0.041, 95% CI: 0.021–0.061, P<0.001).

Clinical Implications

The findings suggest that the pre-festival period may serve as a critical window for targeted interventions in high-risk patients. Healthcare providers should consider cultural events when planning diabetes management strategies.

Conclusion

This study provides evidence that the Spring Festival is associated with a small but significant worsening of long-term glycemic control in high-risk patients.
