Background: University students might experience numerous sources of stress in their daily lives. Previous research has found that stress affects food selection patterns, but the effect might vary by country and sex. No previous study conducted in Saudi Arabia has assessed the association between stress and dietary habits among university students. Thus, this study aimed to examine the association between perceived stress and food selection patterns among undergraduate students by sex at King Saud University (KSU). Methods: A cross-sectional study of 400 students attending the College of Applied Medical Sciences in Riyadh, Saudi Arabia, was conducted. The self-administered questionnaire that was used consisted of three sections: sociodemographic, food frequency questionnaire, and Cohen's Perceived Stress Scale. Results: Approximately (59.0%) of the participants reported suffering from some level of stress, with more females (64.5%) experiencing stress than males (54.0%). The univariate analysis showed that under stress, more females (68.0%) reported eating more than usual than males (49.0%), while the percentage of respondents that reported eating less than usual was higher for females (23.0%) than that for males (31.0%). The McNemar test indicated that under stress, there was an increased preference for salty flavors, which was not associated with sex. Significantly more females (82.0%) than males (64.5%) reported preferring sweets under stress. More males reported preferring bitter and savory flavors than females. Under stress, females preferred homemade food, while males preferred takeout foods. More females (68.0%) reported losing control and overeating than males (49.0%). A logistic regression showed that for female students, perceived stress was associated with frequent consumption of sweets, cake/cookies, snacks and beverages and less frequent consumption of fruits and vegetables. For males, the consumption of fast food and meat was significantly positively associated with perceived stress. Conclusion: Perceived stress led to unhealthy changes in eating patterns in both sexes, as evidenced by reports of an increased preference for sweets, snacks and cake/cookies among females and an increased preference for fast food and meat among males. These results may be potentially important targets for interventions for stress-related food consumption.

Despite the benefits of physical activity (PA) for the management of type 2 diabetes Mellitus (T2DM), the topic of PA is poorly addressed in Saudi Arabia (SA), especially in females with T2DM. The present study examined PA and its associated factors in females with T2DM in Riyadh, Saudi Arabia. This observational cross-sectional study was performed in a random sample of 372 women with T2DM. A face-to-face interview that covered PA, health and environmental correlates of PA was performed. Discriminant analysis was used to determine which barriers had the greatest impact on PA in these women. The results showed that approximately 26.3% of the study participants met PA recommendations. Multivariate linear regression revealed lower levels of PA were associated with women who had more than three children (β =-0.17) compared to women with no children, older age (β =-0.18), women with a duration of diabetes � 6 years (β =-0.16), women who were obese (β =-0.23), women with no family support (β =-0.20), no friend support (β =-0.13) and no healthcare provider support (β =-0.14). Discriminant analysis indicated that culture and tradition, lack of skills and knowledge, safety, fatigue, lack of time, weather conditions, and lack of facilities were the barriers that differentiated between the women who met and those who did not meet the PA recommendations. The present study suggests that the prevalence of PA is low and number of children, age, duration of diabetes, Obesity, family support, friend support and healthcare provider support are identified correlates of PA. These findings are valuable and should be used to design and implement future PA interventions, especially for women with T2DM. Healthcare providers may improve exercise levels and identify the specific barriers to reaching the recommended level of PA to improve health outcomes for each patient.

Background: Kidney dysfunction is a major cause of morbidity and mortality whose prevalence, mainly because of population ageing, is rising worldwide. Also the epidemics of abnormalities clustering with insulin resistance might have played a role in increasing the prevalence of kidney dysfunction. Insulin resistance has been associated with increased risk of cardiovascular events and mortality in multiple large community-based cohort studies. Objective: The aim of the study is to prove that insulin resistance not only may have a role in the development of chronic kidney disease but also may have a role in acute kidney injury. Methods: This was a case-control study. The cases of the study were taken from the medical intensive care unit (ICU) of the Faculty of Medicine Cairo University, 100 control patients stratified by age and gender and 219 critically ill ICU patients with AKI. Results: In the current study, we find that there is statistically significant higher fasting insulin levels and higher levels Homa IR in patients with AKI than patients without AKI. These results signify that patients with AKI had insulin resistance. In our study, the Homa IR showed non-significant correlation with APACHE and SOFA score. While fasting insulin level shows significant correlation only with SOFA score after 96 h. Conclusion: Our present observations indicate that patients with acute kidney injury have statistically significant higher insulin resistance.
