In this study, various health risk behaviours among Government school students in Jordan were assessed. Methods: This cross-sectional descriptive study recruited 1256 students from 20 secondary schools all over the country. Students completed the Global School-based Student Health Survey (GSHS, 2009-2012). The study was conducted in the period between Feb 2016 and Aug 2016. Chi-square (x2) was used to examine differences among the demographic variables. Results: Students scored low in eating breakfast, eating fruit, vegetables, and milk products. However, students scored moderately in hand and mouth hygiene. Students showed minimal incidences of physical attack and physical fight. Although suicidal attempts were not significantly reported, complaining from worries, feeling of sadness and hopelessness were moderately scored. The majority of physical activities were reported from walking or riding bicycles. However, three hours per day was the average of time spent on sitting activities. Students scored lowest in school absenteeism and the majority described their classmates as kind and helpful. Parental control on students' home activities was regarded. Conclusion: In comparison with 2004 and 2007 statistics, students revealed improvements in physical activity, and reduced physical attacks and injuries. Future researchers are encouraged to discover factors associated with these changes.   https://ijph.tums.ac.ir/index.php/ijph/article/view/11764 https://ijph.tums.ac.ir/index.php/ijph/article/download/11764/5847
