High fluoride (F) levels in Iranian groundwater resources were linked to increased hypertension prevalence and systolic blood pressure (SBP) in the population. This study highlights a potential environmental risk factor for cardiovascular health in Iran.
Area of Science:
- Environmental Health
- Cardiovascular Epidemiology
- Public Health
Background:
- The relationship between fluoride (F) intake from drinking water and blood pressure remains largely unexplored.
- Understanding environmental factors influencing blood pressure is crucial for public health initiatives.
Purpose of the Study:
- To investigate the association between fluoride levels in Iranian groundwater resources (GWRs) and the prevalence of hypertension and blood pressure in the Iranian population.
- To explore potential environmental determinants of hypertension in Iran.
Main Methods:
- An ecological study design was employed using existing data on fluoride concentrations in GWRs across Iran.
- Data on hypertension prevalence, systolic blood pressure (SBP), and diastolic blood pressure (DBP) were obtained from a national non-communicable disease risk factor surveillance report.
- Statistical correlation analyses were performed to assess the relationship between fluoride levels and blood pressure parameters.
Main Results:
- Statistically significant positive correlations were observed between mean fluoride concentrations in GWRs and hypertension prevalence in males, females, and the overall population.
- A significant positive correlation was found between mean fluoride concentrations and mean SBP in males, with a borderline correlation in females.
- Higher fluoride levels in drinking water sources were associated with increased hypertension prevalence and SBP.
Conclusions:
- The study suggests a positive association between increased fluoride levels in Iranian GWRs and higher hypertension prevalence and mean SBP.
- Fluoride in drinking water may represent an environmental risk factor contributing to hypertension in the Iranian population.
- Further research is warranted to elucidate the mechanisms and confirm these findings.

Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
Factors affecting Blood pressure
Physiological Factors:
Hormonal Regulation of Blood Pressure
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...

Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart beats)...
