Abstract：
Over the past few decades, people in Saudi Arabia have become less inclined to adopt active lifestyles and healthy eating habits due to the increasing use of digital technologies such as social media. The objective of this online-based cross-sectional study was to assess the role of social media food advertisements and physical activity on eating behaviors among the general population in Saudi Arabia (n = 471). Data were collected through a structured questionnaire, which consisted of four parts: (i) sociodemographic information, (ii) attitude towards social media, (iii) eating behaviors-related information, and (iv) exposure to and engagement with social media advertisements. The study\'s outcome variable, eating behaviors (healthy vs. unhealthy), was assessed using the following question: \"Are you on a healthy diet (such as a balanced diet, keto, or low carb)?\" A multiple binary logistic regression analysis was performed to investigate the factors that influence unhealthy eating behaviors. Approximately 79.6% of the participants had unhealthy eating behaviors. Participants who were not involved in daily physical activity were more likely to have unhealthy eating behaviors compared to their counterparts (adjusted odds ratio, AOR = 4.86). Participants who watched food ads on social media channels 1-3 times a week (AOR = 2.58) or daily (AOR = 3.49) were more likely to have unhealthy eating behaviors than their counterparts. Participants whose appetite to try foods increases always (AOR = 1.42) or usually (AOR = 2.88) after viewing ads on social media were more likely to have unhealthy eating behaviors. These findings suggest that policymakers should take immediate action to regulate food advertising policy to promote a healthy food environment across the country. Saudis should be encouraged to engage in more physical activity, which could support the maintenance of healthy eating patterns and lifestyles.
摘要：
在过去的几十年里，由于社交媒体等数字技术的使用越来越多，沙特阿拉伯人变得不太倾向于采用积极的生活方式和健康的饮食习惯。这项基于在线的横断面研究的目的是评估社交媒体食品广告和体育活动对沙特阿拉伯普通人群饮食行为的作用（n=471）。数据是通过结构化问卷收集的，它由四个部分组成：(I)社会人口统计信息，（二）对社交媒体的态度，(三)饮食行为相关信息，以及(Iv)接触和参与社交媒体广告。研究的结果变量，饮食行为(健康与不健康)，使用以下问题进行评估：“你是否健康饮食(如均衡饮食，keto,或低碳水化合物）？“进行了多元二元逻辑回归分析，以调查影响不健康饮食行为的因素。大约79.6%的参与者有不健康的饮食行为。与其他参与者相比，没有参与日常体育锻炼的参与者更有可能出现不健康的饮食行为（调整后的优势比，AOR=4.86)。每周（AOR=2.58）或每天（AOR=3.49）在社交媒体频道上观看1-3次食品广告的参与者比同龄人更有可能出现不健康的饮食行为。在社交媒体上观看广告后，尝试食物的食欲总是增加（AOR=1.42）或通常（AOR=2.88）的参与者更有可能出现不健康的饮食行为。这些结果表明，政策制定者应立即采取行动，规范食品广告政策，以促进全国健康的食品环境。应该鼓励沙特人进行更多的体育锻炼，这可以支持维持健康的饮食习惯和生活方式。
