Abstract：
Research on healthy behaviour such as physical activity and healthy nutrition and their combination is lacking among university students in Arab countries. The current survey assessed healthy nutrition, and moderate/vigorous physical activity (PA) of 6266 students in Egypt, Libya, and Palestine. We computed a nutrition guideline achievement index using WHO recommendation, as well as the achievement of PA recommendations using guidelines for adults of the American Heart Association guidelines. Latent class regression analysis identified homogenous groups of male and female students, based on their achievements of both guidelines. We examined associations between group membership and achievement of guidelines. A three-class solution model best fitted the data, generating three student Groups: \"Healthy Eaters\" (7.7% of females, 10.8% of males), \"Physically Active\" (21.7% of females, 25.8% of males), and \"Low Healthy Behaviour\" (70.6% of females, 63.4% of males). We did not observe a latent class that exhibited combined healthy behaviours (physically active and healthy eaters), and there were no major differences between countries. We observed a very low rate of healthy nutrition (≈10% of students achieved greater than four of the eight nutrition guidelines), with little gender differences across the countries. About 18-47% of students achieved the PA guidelines, depending on country and gender, more often among males. Few females achieved the PA guidelines, particularly in Libya and Palestine. Culturally adapted multi-behavioural interventions need to encourage healthy lifestyles, nutrition and PA behaviours. National policies need to promote active living while addressing cultural, geographic, and other barriers to young adults\' engagement in PA.
摘要：
阿拉伯国家的大学生缺乏对健康行为的研究，例如体育锻炼和健康营养及其结合。当前的调查评估了健康的营养，埃及6266名学生的中等/剧烈体力活动（PA），利比亚,和巴勒斯坦。我们使用世卫组织的建议计算了营养指南成就指数，以及使用美国心脏协会指南的成人指南实现PA建议。潜在班级回归分析确定了同质的男女学生群体，基于他们对这两个准则的成就。我们检查了组成员资格与指南成就之间的关联。三级解决方案模型最好地拟合了数据，产生三个学生群体：“健康饮食者”(7.7%的女性，10.8%的男性)，“身体活跃”(21.7%的女性，25.8%的男性)，和“低健康行为”(70.6%的女性，63.4%的男性)。我们没有观察到一个潜在的类别，表现出相结合的健康行为（身体活跃和健康的饮食），国家之间没有重大差异。我们观察到健康营养的比率非常低（约10％的学生达到了八项营养指南中的四项以上），各国的性别差异很小。大约18-47％的学生达到了PA指南，根据国家和性别，更多的是男性。很少有女性达到PA指南，特别是在利比亚和巴勒斯坦。文化适应的多行为干预需要鼓励健康的生活方式，营养和PA行为。国家政策需要促进积极生活，同时解决文化、地理,以及其他阻碍年轻人参与PA的障碍。
