Determining the stages of change in physical activity (PA) helps to determine effective promotion of PA interventions. The aim of the study was to assess the readiness of students of King Saud University (KSU) to be more physically active and relate this to their self efficacy, perceived benefits and perceived barriers to PA.
A cross-sectional descriptive study was conducted at KSU, Riyadh, between March and May 2007, using a self-administered questionnaire. The total sample size was 302 randomly chosen male and female students.
More than half of the students (55.3%) reported that they participated in PA in the action (for <6 months) and maintenance (for ≥ 6 months) stages. The remaining students did not engage in PA as they were in precontemplation, contemplation, preparation and relapse stages. More males were found in the maintenance stage, but more females were found in the inactive stages (precontemplation, contemplation and preparation). Only 24.4% of the students were engaged in PA as much as three times or more/week and 9.9% engaged in PA regularly through out the year. About 39% of which, significantly, more were males did vigorous PA for 20 minutes or more. However, 4.6% described themselves as hyperactive. More females used the stairs, did house work and considered themselves moderately active. Nearly 50% had a low total score of perceived barriers while 85% had high perceived benefits and 63.6% had moderate self efficacy of PA. The main barriers perceived were time and resources. The score relating to barriers decreased significantly across stages of change, but the pattern was reversed with regard to the perceived benefits and self-efficacy (p<0.05).
Physical inactivity is common among KSU students. A considerable proportion of them was not ready to become more physically active. The study highlights the need to adapt PA promotion programs to states of readiness for PA. University and public policies as well as environmental changes are necessary to encourage active living within the context of Islamic rules and Saudi culture.
确定身体活动（PA）的改变阶段有助于确定促进PA干预措施的有效性。本研究的目的是评估沙特国王大学（KSU）学生增加身体活动的意愿，并将其与自我效能感、感知到的益处以及PA的感知障碍联系起来。
2007年3月至5月期间，在利雅得的KSU进行了一项横断面描述性研究，使用自行填写的问卷。总样本量为302名随机选择的男女学生。
超过一半的学生（55.3%）报告称他们处于行动阶段（<6个月）和维持阶段（≥6个月）参与了PA。其余学生由于处于前思考、思考、准备和复发阶段而未参与PA。维持阶段的男性更多，但不活跃阶段（前思考、思考和准备）的女性更多。只有24.4%的学生每周进行三次或更多次PA，9.9%的学生全年定期进行PA。其中约39%，显著地，更多男性进行了20分钟或更长时间的剧烈PA。然而，4.6%的学生将自己描述为多动。更多女性使用楼梯、做家务并认为自己活动适度。近50%的学生感知障碍总分较低，而85%的学生感知益处较高，63.6%的学生PA自我效能感中等。主要感知到的障碍是时间和资源。与障碍相关的得分在改变阶段显著下降，但在感知益处和自我效能感方面则相反（p<0.05）。
身体不活动在KSU学生中很常见。他们中相当一部分人尚未准备好增加身体活动。该研究强调需要使PA促进计划适应PA的准备状态。在伊斯兰规则和沙特文化背景下，大学和公共政策以及环境变化对于鼓励积极生活是必要的。
