The senior population represents today a significant share in most countries, being susceptible to not transferable chronic diseases that may be associated with vitamin A status and the presence of inflammation. The aim of this study was therefore to verify the association of serum retinol, C-reactive protein and total fiber intake with hypertension in the elderly in the city of Joao Pessoa. This is a cross-sectional epidemiological research, population-based, with 212 individuals between 60 to 90 years old, both sexes, with or without chronic diseases and use of antihypertensive medication or not. The dietary survey was conducted by the Quantitative Food Frequency Questionnaire, retinol serum by liquid chromatography high resolution and the CRP ultrasensitive (hs-CRP) by particle agglutination by latex; for statistical analysis was applied Fisher Exact Test, which was adopted a significance level of 5% to reject the null hypothesis. The prevalence of hypertension alone was 48.08% and other morbidities associated with hypertension was 51.92%, 97.85% of elderly hypertensives were using hypotensive and had adequate levels of serum retinol (&#8805; 1.05 mmol / L), 89.13% had adequate levels of CRP (<8.5 mg / dL for females and <7.9 mg / dL for males) and 96.77% had inadequate intake of fiber (&#8805; 30 g / day for men and &#8805; 21g/dia for females). There was no significant relationship between serum retinol and hypertension (p = 0.1661) or between CRP and hypertension (p = 0.557). There was a significant association between inadequate intake of fiber and hypertension (p = 0.0035), suggesting for the first time in the elderly of different socioeconomic levels, based on the literature, that this group of hypertensive patients should be informed about the positive function of adequated consumption of fiber and it may helps the treatment of hypertension and thus reduce the amount of hypotensive drugs used by this population. We conclude that, even considering the inadequate consumption of fiber, most of the elderly hypertensive population showed serum retinol and CRP-us appropriate, probably, these values did not rise because it is the elderly hypertensive patients without acute inflammation or other chronic decompensated diseases.
