The aim was to examine the association between habitual consumption of dairy products and 24-hour ambulatory blood pressure monitoring among older adults with hypertension.
We conducted an analysis of 715 community-living hypertensive adults age ≥60. Habitual dairy consumption was assessed with a validated diet history. Blood pressure was recorded by 24-hour ambulatory blood pressure monitoring; controlled blood pressure was defined as 24-hour blood pressure <130/80mm Hg in those under drug treatment. Analyses were adjusted for main confounders, including diet, hypertension duration, and being on antihypertensive treatment.
After adjustment for confounders, consumers of ≥7 servings/week of whole-fat milk/yogurt had a diastolic blood pressure 1.40mm Hg higher (95% confidence interval, 0.01, 2.81) than consumers of <1 serving/week. By contrast, consumers of ≥7 servings/week of low-fat milk/yogurt had a diastolic blood pressure 1.74mm Hg lower (95% confidence interval, -3.26, -0.23) than consumers of <1 serving/week. Moreover, the odds ratio (95% confidence interval) for controlled blood pressure was 1.83 (1.05-3.08) for those consuming ≥7 servings/week of low-fat milk/yogurt, when compared with consumers of <1 serving/week. Cheese consumption was not associated with blood pressure.
Regular consumption of low-fat milk/yogurt was associated with lower 24-hour diastolic blood pressure and with better blood pressure control among older adults with hypertension.
本研究旨在探讨习惯性乳制品摄入与老年高血压患者 24 小时动态血压监测之间的关系。
我们对 715 名年龄≥60 岁的社区居住的高血压成年人进行了分析。习惯性乳制品摄入通过经过验证的饮食史进行评估。通过 24 小时动态血压监测记录血压；在接受药物治疗的人群中，将血压控制定义为 24 小时血压<130/80mmHg。分析调整了主要混杂因素，包括饮食、高血压持续时间和服用抗高血压药物。
调整混杂因素后，每周食用≥7 份全脂牛奶/酸奶的消费者舒张压比每周食用<1 份的消费者高 1.40mmHg（95%置信区间，0.01，2.81）。相比之下，每周食用≥7 份低脂牛奶/酸奶的消费者舒张压比每周食用<1 份的消费者低 1.74mmHg（95%置信区间，-3.26，-0.23）。此外，与每周食用<1 份的消费者相比，每周食用≥7 份低脂牛奶/酸奶的消费者血压控制的比值比（95%置信区间）为 1.83（1.05-3.08）。食用奶酪与血压无关。
定期食用低脂牛奶/酸奶与老年高血压患者 24 小时舒张压降低和血压控制更好相关。
