Evaluating the Effect of a Magnesium-Focused Nutritional Intervention on Blood Pressure Among Individuals With Type 2 Diabetes Mellitus in Saudi Arabia: A Within-Subject Study.

BACKGROUND

Hypertension increases cardiovascular risk in type 2 diabetes mellitus (T2DM) patients. Magnesium is an important nutrient that promotes vascular function and insulin sensitivity, yet its potential role in managing blood pressure (BP) in patients with T2DM remains unclear. This study evaluates the impact of a magnesium-focused nutrition education intervention on dietary magnesium intake and BP control in patients with T2DM.

METHODS

Thirty patients with T2DM (25 women; mean age, 55.7 ± 9.8 years; body mass index, 33.44 ± 7.17 kg/m2) participated in two clinical visits for data collection and BP measurement and received 12 weeks of magnesium-focused nutrition education to promote dietary magnesium intake.

RESULTS

The education intervention significantly increased dietary magnesium intake by 81.81 mg (p < 0.001). However, there were no significant changes in systolic or diastolic BP. Analysis showed no significant correlation between dietary magnesium intake and systolic or diastolic BP (p ≥ 0.56).

CONCLUSION

While the intervention successfully increased dietary magnesium intake, it did not affect BP. These findings suggest that increasing dietary magnesium intake through nutrition education may not significantly impact BP in individuals with T2DM. However, further research is needed to confirm these results and explore other factors that may influence BP management in this population.
