So, we investigated the correlation between vitamin D intake and the mean blood pressure in the elderly with and without nursing care. </span></p><p><span class="fontstyle0"><strong>Methods</strong>: </span><span class="fontstyle2">Based on a cross‑sectional design, this study was conducted on 152 old people with and without nursing care. Assessment of the dietary intake of nutrients was done by an expert dietitian using food frequency questionnaire and nutritionist IV software analyzer. Also, the mean blood pressure was extracted from participants’ fles. The independent samplet‑test, Chi‑square test, and partial correlation test were used for data analysis.</span></p><p><strong></strong><span class="fontstyle0"><strong>Results</strong>: </span><span class="fontstyle2">Mean ± SD age, weight, height, body mass index (BMI) of participants, and the percentage of male/females were 68.7 ± 5.5 years, 63.5 ± 7.9 kg, 162.5 ± 7.1 cm, 24.1 ± 3.4 kg/m</span><span class="fontstyle2" style="font-size: 5pt;">2 </span><span class="fontstyle2">and 48.7/51.3, respectively. Also, a signifcant negative relationship was observed between vitamin D intake and systolic blood pressure in all participants (</span><span class="fontstyle3">P </span><span class="fontstyle2">value = 0.028, </span><span class="fontstyle3">r </span><span class="fontstyle2">= -0.179). There was no signifcant correlation between vitamin<br />D intake and diastolic blood pressure (</span><span class="fontstyle3">P </span><span class="fontstyle2">value = 0.558, </span><span class="fontstyle3">r </span><span class="fontstyle2">= -0.048). </span></p><p><span class="fontstyle0"><strong>Conclusions</strong>: </span><span class="fontstyle2">The fndings revealed that the nursing care can improve dietary intake of vitamin D in the elderly population. Also, a negative correlation was found between vitamin D intake and systolic blood pressure among all the elderly.<br /></span></p><p><span class="fontstyle0" style="color: #00652e;"><strong>Keywords</strong>: </span><span class="fontstyle3">Blood pressure, diet, elderly, vitamin D</span></p>http://ijpm.mui.ac.ir/index.php/ijpm/article/view/2027http://ijpm.mui.ac.ir/index.php/ijpm/article/download/2027/717717849
