Background: Cigarettes smoking and obesity are major public health problems and leading causes of preventable morbidity and mortality worldwide. The aim of this study was to investigate the relationship between cigarettes smoking and body weight status among Northern Saudi subjects.

Background: Social media (SM) use is increasing among young adults in Saudi Arabia, and it's becoming an integral part of everyday life. It is thought that social media use is associated with certain behavioral changes, and some authors have shown concerns about its possible effect on mental health. In this study, we investigated the relationship between social media use and depression indicators among adult population in Saudi Arabia. Methods: A total of 618 adults were surveyed about SM and depression with an age range of 16 to 40 years. SM use was assessed by self-reported total number of hours per day spent on social networking. And depression was assessed using Beck Depression Inventory (BDI-II) scale. Also participants were asked to provide data on personal and family history of psychiatric disorders, drug abuse, and demographic data. Descriptive frequencies, Chi-squared tests and ordered logistic regressions were performed on data for analysis using SPSS software version 20.0. Results: Average daily time spent on social networking was 4 hours with standard deviation (SD) of 1.05 hour. Twitter, Snapchat and whatsapp were the most visited social networking applications by participants (85.7%, 74.2% and 67. 2%, respectively). BDI-II score indicated no depression in 572 participants, mild depression in 40 participants, and moderate to severe depression in 4 participants. Compared to those with lowest total hours per day spent on SM, participants with highest total hours per day spent on SM had significantly higher scores of BDI-II (AOR = 1.36, 95% CI = 1.09-2.42). Conclusion: Our results indicate that frequent use of social media is related to depression. Additional research is required to determine the possible causal nature of this relationship.

Background: Head injury is one of the most common causes of death following trauma worldwide. Epidemiological data of traumatic head injuries (THI) is important for establishing prevention program. Such data are few in our region. For that reason our primary goal was to study the descriptive features and outcomes of THI among adult patients presented at King Khalid General Hospital in Hail, Saudi Arabia. Methods: A hospital-based, retrospective, cross-sectional study was conducted at King Khalid General Hospital in Hail, Saudi Arabia. All patients who were admitted with THI, from April 2016 to April 2017 were identified through a trauma database, which includes cases that required hospital admission or died in the emergency department. The records of 89 patients were reviewed. Characteristics of patients and injury-related data were obtained. The data were entered into Excel sheet and exported to SPSS version 20 statistical package for further analysis. Descriptive statistics were used to explore the data in relation to relevant variables. Binary logistic regression analysis was employed. Odds ratio with 95% confidence intervals (CI) was computed to identify relations between the variables. Results: We reviewed the records of 89 adult patients met the inclusion criteria with a mean age of 29.6 years and a male predominance of 93.1%. Most injuries were secondary to motor vehicle collisions (MVC; 71.2%). Only 10.7% of patients had a severe THI (Glasgow coma score, GCS < 8). The overall mortality rate was 21%. Mortality was significantly associated with older age (P=0.0001) and lower GCS (P=0.0001). Outcome was good in majority of patients (88.5%). Conclusion: This study indicated that outcome of THI is affected by age and GCS of patients.
