为了确定是否饮食方法停止高血压(DASH)饮食或替代,简化饮食,强调高纤维水果和蔬菜,降低血清尿酸盐(SU)。我们进行了DASH喂养研究的二次研究,这是一项3臂、平行设计、随机试验,纳入了459名收缩压(SBP)<160 mmHg、舒张压(DBP)80-95 mmHg的成年人,未使用BP药物。参与者被随机分配到8周的监测喂养,并吃三种饮食之一:1)典型的美国饮食(对照),2)富含水果和蔬菜(FV)的饮食,但其他方面与对照相似,或3)DASH饮食,富含水果,蔬菜和低脂乳制品,并减少脂肪,饱和脂肪和胆固醇。在整个研究期间,体重保持恒定。在基线和喂养8周后测量SU。在327例有可用样本的受试者中(平均年龄45.4±11.0岁,47%为女性,50%为黑人),平均基线SU为5.7±1.5 mg/dL。与对照饮食相比,FV饮食使SU降低0.17 mg/dL(95%CI:-0.34,00; P=0.051),DASH使SU降低0.25 mg/dL(95%CI:-0.43,-0.08; P=0.004)。这些影响随着基线SU水平(<5、5-5.9、6-6.9、7-7.9和≥8 mg/dL)的增加而增加,DASH(0.08、0.12、0.42、0.44和0.73 mg/dL; P趋势=0.04),但FV不增加。DASH饮食减少了SU,特别是高尿酸血症患者。这些发现支持了对一项专门试验的日益增长的需求,以测试高尿酸血症和痛风患者中的DASH。
To determine whether the Dietary Approaches to Stop Hypertension (DASH) diet or an alternative, simplified diet, emphasizing high fiber fruit and vegetables, lowers serum urate (SU). We conducted a secondary study of the DASH feeding study, a 3-arm, parallel-design, randomized trial of 459 adults with systolic blood pressure (SBP) <160 mmHg and diastolic blood pressure (DBP) of 80–95 mmHg, not on BP medications. Participants were randomized to 8 weeks of monitored feeding and ate one of three diets: 1) a typical American diet (control), 2) a fruit and vegetable (FV)-rich diet but otherwise similar to control, or 3) the DASH diet which was rich in fruit, vegetables, and low-fat dairy products, and reduced in fat, saturated fat and cholesterol. Body weight was kept constant throughout the study. SU was measured at baseline and after 8-weeks of feeding. Of the 327 participants with available specimens (mean age 45.4±11.0 years, 47% women, 50% black), mean baseline SU was 5.7±1.5 mg/dL. Compared to the control diet, the FV diet reduced SU by 0.17 mg/dL (95%CI: −0.34, 00; P=0.051) and DASH reduced SU by 0.25 mg/dL (95%CI: −0.43,−0.08; P=0.004). These effects increased with increasing baseline SU levels (<5, 5–5.9, 6–6.9, 7–7.9, and ≥8 mg/dL) with DASH (0.08, 0.12, 0.42, 0.44, and 0.73 mg/dL; P-trend=0.04), but not with FV. The DASH diet reduced SU, particularly among those with hyperuricemia. These findings support the growing need for a dedicated trial to test DASH among patients with hyperuricemia and gout.
