title: [25-hydroxyvitamin D concentrations and blood pressure levels in hypertensive elderly patients].
abstract: 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.
  
  
  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.
  
  
  CONCLUSIONS
  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.
