To determine if participants would be interested in consuming soy foods to lower cholesterol in primary and secondary prevention of heart disease, and to identify the role physicians and registered dietitians have in providing dietary advice, about soy foods or other foods, for participants with elevated cholesterol.
Qualitative data from 12 focus groups were gathered from a convenience sample of 74 adults, aged 18-91 years, with and without high cholesterol (total cholesterol >200 mg dl(-1)). Participants were recruited from Minneapolis/St. Paul mainstream and natural foods grocery stores. Focus group interviews were taped and transcribed verbatim. Common themes were identified, coded and compared using NVivo computer software.
Participants believed diet, lifestyle and genetics were the cause of high cholesterol and cardiovascular disease (CVD). Few participants were aware of the Food and Drug Administration health claim for soy protein, yet many were willing to consume soy as part of lifestyle modification to prevent CVD. They reported preferring food and exercise over medication to treat high cholesterol. Few participants had ever received dietary advice from physicians on treating high cholesterol or CVD, and most doubted the accuracy of such advice. They believed registered dietitians were the most credible source of nutrition counselling and expressed an interest in physician referrals to dietitians.
A collaboration and referral system between physicians and registered dietitians could increase CVD patients' consumption of soy foods as a means potentially leading to a reduced risk of heart disease in participants.
确定参与者是否有兴趣食用大豆制品以在心脏病的一级和二级预防中降低胆固醇,并确定医生和注册营养师在为胆固醇升高的参与者提供有关大豆制品或其他食物的饮食建议方面所起的作用。
从74名年龄在18至91岁之间、有或没有高胆固醇(总胆固醇>200mg/dl)的成年人的便利样本中收集了12个焦点小组的定性数据。参与者是从明尼阿波利斯/圣保罗的主流和天然食品杂货店招募的。焦点小组访谈进行了录音并逐字转录。使用NVivo计算机软件确定、编码和比较共同主题。
参与者认为饮食、生活方式和遗传是高胆固醇和心血管疾病(CVD)的原因。很少有参与者知道美国食品药品监督管理局对大豆蛋白的健康声明,但许多人愿意将食用大豆作为生活方式改变的一部分来预防CVD。他们报告说,比起药物治疗,他们更喜欢通过饮食和运动来治疗高胆固醇。很少有参与者曾从医生那里得到过关于治疗高胆固醇或CVD的饮食建议,而且大多数人怀疑这种建议的准确性。他们认为注册营养师是营养咨询最可靠的来源,并表示有兴趣让医生将他们转介给营养师。
医生和注册营养师之间的合作及转介系统可以增加CVD患者食用大豆制品的量,这可能是降低参与者心脏病风险的一种方式。
