The objective of this prospective, randomized controlled trial was to assess the effectiveness of the Food For Heart Program patient nutrition tool in hypercholesterolemic outpatients. The setting for this study was an urban academic primary-care practice; 175 hypercholesterolemic adults not taking cholesterol-lowering medications were enrolled as subjects. The study intervention involved four monthly dietary counseling visits, using the Food For Heart Program, conducted by the study research assistant. The main outcome measures were fasting serum lipids (primary); body weight (secondary); and change in Dietary Risk Assessment score (intervention group only), analyzed using Student's t test. Our results showed that total and low-density lipoprotein cholesterol decreased 0.40+/-0.65 mmol/L and 0.32+/-0.58 mmol/L, respectively, in the intervention group (n=91), compared with 0.06+/-0.57 mmol/L and 0.0088+/-0.56 mmol/L in the control group (n=84) ( P <.001). There was no significant change in high-density lipoprotein cholesterol. Intervention subjects lost a small but statistically significant amount of weight, 2.2+/-7.4 pounds ( P <.01), and decreased their Dietary Risk Assessment score 5.9+/-6.5 points ( P <.001). Based on these findings, we concluded that total and low-density lipoprotein cholesterol, weight, and dietary risk for coronary heart disease decreased significantly in hypercholesterolemic patients counseled using the Food For Heart Program.
这项前瞻性随机对照试验的目的是评估“心脏健康饮食计划”患者营养工具对高胆固醇血症门诊患者的有效性。本研究的开展地点是一家城市学术性初级保健机构;175名未服用降胆固醇药物的高胆固醇血症成年人被招募为研究对象。研究干预包括由研究助理开展的四次每月一次的饮食咨询访视,使用“心脏健康饮食计划”。主要结局指标为空腹血脂(主要指标)、体重(次要指标)以及饮食风险评估得分的变化(仅针对干预组),采用学生t检验进行分析。我们的结果显示,干预组(n = 91)的总胆固醇和低密度脂蛋白胆固醇分别下降了0.40±0.65 mmol/L和0.32±0.58 mmol/L,而对照组(n = 84)分别下降了0.06±0.57 mmol/L和0.0088±0.56 mmol/L(P <.001)。高密度脂蛋白胆固醇没有显著变化。干预组受试者体重减轻了少量但具有统计学意义的重量,为2.2±7.4磅(P <.01),饮食风险评估得分下降了5.9±6.5分(P <.001)。基于这些发现,我们得出结论,使用“心脏健康饮食计划”对高胆固醇血症患者进行咨询后,其总胆固醇、低密度脂蛋白胆固醇、体重以及冠心病的饮食风险均显著降低。
