A retrospective cohort study on the relationship between a proactive health check-up follow-up intervention based on a company restriction criteria and changes in health markers

Abstract

Abstract:

Objectives:

In view of the aging of the Japanese workforce, promoting occupational health activities to reduce health risks among workers is essential. This retrospective cohort study evaluated and analyzed PHC Corporation's proactive follow-up activities after regular health check-ups.

Methods:

The study examined changes after two years in blood pressure, blood glucose, and lipid levels among PHC employees. It compared proactive follow-ups in districts where an occupational health physician conducted interviews based on standard values for work restriction with those implemented in districts with conventional follow-ups, where an occupational health physician made judgement based on their original perspective.

Results:

In comparison with districts implementing conventional follow-up measures, those with advanced follow-up were significantly associated with improvements in systolic blood pressure, diastolic blood pressure, blood glucose, low-density lipoprotein (LDL) cholesterol levels, and high-density lipoprotein (HDL) cholesterol levels from 2017 to 2019. No significant changes were observed in HbA1c levels.

Conclusions:

Implementing proactive interventions based on work restriction criteria improved health markers, including systolic and diastolic blood pressure, blood glucose, LDL cholesterol, and HDL cholesterol levels. Further analysis of the ongoing results and the accumulation of evidence from other companies will be crucial for future research.
