Occupational health management reduced systolic and diastolic BP in hypertensive dock workers significantly (SBP decreased with β=−2.32 mmHg/year, DBP β=−2.66 mmHg/year, both Ptrend<0.001) and lowered hypertension incidence from 22.45% in 2020 to 3.25% in 2023 (Ptrend<0.001).
Do occupational health management measures reduce blood pressure and the incidence of hypertension among dock workers?

Occupational health management interventions can effectively reduce blood pressure and slow the rising prevalence of hypertension among high-risk occupational groups like dock workers.
What is already known about this topic? Hypertension predisposes dock workers to higher health risks in their work environments, requiring urgent intervention via comprehensive health management. What is added by this report? This study explored occupational health management in hypertension among dock workers and found that occupational health management measures helped reduce the blood pressure of patients with hypertension, curb the incidence, and slow the growth rate of its prevalence. What are the implications for public health practice? The intervention measures adopted in this study should be promoted in similar occupational environments.

Naixing et al. (Thu,) conducted a other in Dock workers in Shenzhen, China, aged ≥18, engaged in dock operations, with a median age of 46 years and predominantly male (97.6%), including patients with and without baseline hypertension (n=1,145). Occupational health management measures including daily pre-shift blood pressure monitoring and hierarchical management, quarterly health training, dietary management with low-salt food options, and exercise promotion vs. No control group (pre-post intervention within cohort) was evaluated on Change in blood pressure levels, incidence and prevalence of hypertension during intervention period (Incidence of hypertension decreased from 22.45% in 2020 to 3.25% in 2023; prevalence increased but annual growth rate slowed (annual growth rate decreased from 50.7% to 4.4%), p=<0.001). Occupational health management reduced systolic and diastolic BP in hypertensive dock workers significantly (SBP decreased with β=−2.32 mmHg/year, DBP β=−2.66 mmHg/year, both Ptrend<0.001) and lowered hypertension incidence from 22.45% in 2020 to 3.25% in 2023 (Ptrend<0.001).
