Abstract：
This study aimed to determine the consumption status of functional drinks based on the theory of planned behavior and the Stages of Change Model. This study was conducted on 536 female employees of Birjand offices in 2022. The data was collected by using the functional food questionnaire and was analyzed using SPSS with significance level of P < 0.05. The largest number of people consume probiotic drinks (buttermilk, kefir, etc.) were in the maintenance stages (31.2%) and who consume milk fortified with vitamin D were in the contemplation stage (37.3%). The mean score of the participants in the subscales of attitude, behavioral control, and subjective norm was 17.69 ± 3.05, 16.83 ± 2.88, 21.73 ± 4.33, respectively. The mean score of the attitude and subjective norm regarding the consumption of all drinks had a significant relation with the stages of change model (p < 0.05). The results of this study showed that the most drinks that female employees consumed regularly were probiotic drinks, while they did not intend to use functional juices (pre-contemplation stage). Therefore, it seems that this theory can be used as a framework in designing educational programs in order to increase the consumption of functional foods and improve women\'s health.
摘要：
本研究旨在基于计划行为理论和变化阶段模型来确定功能饮料的消费状况。这项研究是在2022年对Birjand办公室的536名女性员工进行的。采用功能性食品问卷收集数据,采用SPSS进行统计学分析,显著性水平P<0.05。最多的人食用益生菌饮料（酪乳，kefir,等。)处于维持阶段(31.2%)，食用维生素D强化牛奶的人处于沉思阶段(37.3%)。态度量表中参与者的平均得分，行为控制,主观常模分别为17.69±3.05、16.83±2.88、21.73±4.33。关于所有饮料消费的态度和主观规范的平均得分与变化模型的阶段有显着关系（p<0.05）。这项研究的结果表明，女性员工经常饮用的大多数饮料是益生菌饮料，而他们不打算使用功能性果汁（沉思前阶段）。因此,这个理论似乎可以作为一个框架来设计教育计划，以增加功能性食品的消费，改善女性的健康。
