为了评价阶段性算法计算奶制品中钙摄入量的有效性,在男大学生中进行了试验。之前已经证明在女大学生中是有效的。从美国私立大学中,随机抽取180名男大学生作为参加者。采用自我报告的方式,完成26条食物频率调查表确定钙摄入量。阶段变化的基础是通过4个问题来计算奶制品中的钙量和3条自我功效的调查表。奶制品中钙摄入量在无计划组、计划/准备组、行动/坚持组之间有显著性差异。结果显示,46%的参加者位于行动坚持阶段。行动之前和行动阶段的自我功效也有显著性差异。研究表明,奶制品中钙摄入量阶段性算法应用于男大学生是有效的。 In order to evaluate the validity of the phased algorithm for calculating calcium intake in dairy products, tests were conducted among male college students. It has been proved effective among female college students before. From the United States private universities, randomly selected 180 male college students as participants. Using a self-report approach, 26 food frequency questionnaires were completed to determine calcium intake. The phase change is based on a questionnaire that calculates the amount of calcium in the dairy product and three self-efficacy questions using four questions. There was a significant difference in calcium intake in dairy products between the unplanned, planned / prepared and active / insisted groups. The results showed that 46% of the participants were in the action-keeping phase. There was also a significant difference in self-efficacy before and during the course of action. Studies have shown that the phased algorithm of calcium intake in dairy products is effective for male college students.
