Objective:
To evaluate the prevalence of inadequate vitamin D status and its relationship with associated factors in 91 elderly hypertensive patients in João Pessoa, PB/BR.
Materials And Methods:
In a cross-sectional study, levels of 25-hydroxyvitamin D of 91 elderly patients were compared with biochemical, anthropometric, and dietary data, type of skin, exposure to sunlight, and blood pressure.
Results:
The prevalence of inadequate vitamin concentrations (25-hydroxyvitamin D < 29 ng/mL) was 33%. The concentration of serum 25-hydroxyvitamin D was inversely associated with systolic blood pressure and positively associated with weekly fish consumption. The other variables showed no significant association with 25-hydroxyvitamin D.
Conclusion:
The prevalence of inadequate vitamin D concentrations was related with higher blood pressure in elderly patients. Moreover, greater fish weekly consumption influenced greater 25-hydroxyvitamin D concentration.

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
Alterations in Blood Pressure
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)...
