BACKGROUND
Population studies have demonstrated that there is an inverse association between dietary intake of vitamin D and the mean blood pressure in elderly in particular. So, we investigated the correlation between vitamin D intake and the mean blood pressure in the elderly with and without nursing care.
METHODS
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' files. The independent samplet-test, Chi-square test, and partial correlation test were used for data analysis.
RESULTS
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 and 48.7/51.3, respectively. Also, a significant negative relationship was observed between vitamin D intake and systolic blood pressure in all participants ( value = 0.028, = -0.179). There was no significant correlation between vitamin D intake and diastolic blood pressure ( value = 0.558, = -0.048).
CONCLUSIONS
The findings 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.
背景
人群研究表明，尤其是在老年人中，维生素D的饮食摄入量与平均血压之间存在负相关。因此，我们调查了有无护理的老年人中维生素D摄入量与平均血压之间的相关性。
方法
基于横断面设计，本研究对152名有无护理的老年人进行。营养饮食摄入量由专业营养师通过食物频率问卷和营养师IV软件分析仪进行评估。此外，从参与者的档案中提取平均血压。采用独立样本t检验、卡方检验和偏相关检验进行数据分析。
结果
参与者的平均±标准差年龄、体重、身高、体重指数（BMI）以及男性/女性百分比分别为68.7±5.5岁、63.5±7.9千克、162.5±7.1厘米、24.1±3.4千克/平方米和48.7/51.3。此外，在所有参与者中，维生素D摄入量与收缩压之间存在显著负相关（P值=0.028，r=-0.179）。维生素D摄入量与舒张压之间无显著相关性（P值=0.558，r=-0.048）。
结论
研究结果表明，护理可以改善老年人群维生素D的饮食摄入量。此外，在所有老年人中，维生素D摄入量与收缩压之间存在负相关。
