Description
Summary: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. 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. 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. 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.
