Summary

Cold exposure is linked to higher blood pressure in workers. Factors like age, cold severity, and milk intake influence hypertension risk, suggesting reduced exposure and calcium-rich foods are beneficial.

Area of Science:

Occupational Health
Cardiovascular Physiology
Environmental Medicine

Background:

Hypertension is a significant global health concern.
Occupational cold exposure may impact cardiovascular health.
Understanding risk factors in cold-exposed workers is crucial.

Purpose of the Study:

To investigate the relationship between occupational cold exposure and hypertension.
To identify specific risk factors for hypertension in cold-exposed workers.

Main Methods:

Comparative study involving 68 cold-exposed male workers and 68 controls.
Data collection through questionnaire surveys, clinical examinations, and laboratory tests.
Logistic regression analysis to determine significant risk factors.

Main Results:

Cold-exposed workers exhibited significantly higher systolic and diastolic blood pressures.
Body core temperature was significantly lower in the cold-exposed group.
Age, cold exposure severity, and milk intake were identified as significant predictors of hypertension.

Conclusions:

Occupational cold exposure is a risk factor for developing hypertension.
Key modifiable factors include minimizing cold exposure duration and increasing calcium intake (e.g., milk).
Periodic health monitoring, including blood pressure and ECG, is recommended for older workers in cold environments.
