Abstract：
BACKGROUND: Coronary artery disease (CAD) is the most common cardiovascular disease (CVD) and the main cause of mortality in developed and developing countries. Physical activity and nutritional behaviors are modifiable factors in people at the risk of CAD and its risk factors; thus, the present study aimed to design, implement, and evaluate an intervention based on the social cognitive theory for physical activity and nutritional behaviors in the middle-aged population at the risk of CAD residing in Bandar Abbas city.
METHODS: The present study will be conducted in three phases: qualitative, cross-sectional, and community-based intervention. The middle-aged population with less than 150 minutes of physical activity a week with at least one other risk factor of CAD (hyperlipidemia, hypertension, diabetes, overweight and obesity, smoking) will be included in the study. In the qualitative phase of study, the participants will be selected with maximum diversity and with the aim of obtaining comprehensive information to clarify the nature and dimensions of the phenomenon in question. The cross-sectional phase aimed to determine the intensity of physical activity and nutritional behaviors. By analyzing the data obtained from the cross-sectional phase, the most important constructs of the social-cognitive theory in physical activity and nutritional behaviors will be determined, and accordingly, an effective intervention will be designed. The third phase of the pre-test-post-test intervention study will include a randomized control group. The interventions will be a combination of face-to-face meetings and the use of educational technologies. Individuals in the control group will not undergo the educational intervention. Those in the intervention group will be evaluated in two phases (before the implementation of the intervention, and 3 months after the intervention).
CONCLUSIONS: The findings of the present study can be used as a strategic plan to help policy makers to strengthen CVD prevention and management alternatives to include physical activity and nutritional behavior as part of their preventive measures.

摘要：
背景：冠状动脉疾病（CAD）是最常见的心血管疾病（CVD），是发达国家和发展中国家的主要死亡原因。身体活动和营养行为是冠心病风险人群及其危险因素的可改变因素；因此，本研究旨在设计，工具，并评估基于社会认知理论对居住在阿巴斯港市的有CAD风险的中年人群的身体活动和营养行为的干预措施。
方法：本研究将分三个阶段进行：定性，横截面,基于社区的干预。每周体力活动少于150分钟的中年人群，至少有一种其他CAD危险因素（高脂血症，高血压,糖尿病,超重和肥胖，吸烟)将被纳入研究。在定性研究阶段，将以最大的多样性选择参与者，目的是获得全面的信息，以澄清有关现象的性质和范围。横截面阶段旨在确定身体活动和营养行为的强度。通过分析从横截面阶段获得的数据，将确定体育活动和营养行为中社会认知理论的最重要结构，因此，将设计有效的干预措施。测试前-测试后干预研究的第三阶段将包括一个随机对照组。干预措施将是面对面会议和使用教育技术的结合。对照组中的个体将不进行教育干预。干预组中的人员将分两个阶段进行评估（在实施干预之前，和干预后3个月)。
结论：本研究的结果可用作一项战略计划，以帮助政策制定者加强心血管疾病预防和管理替代方案，包括身体活动和营养行为作为其预防措施的一部分。
