Background Chronic disease burden is increasing globally. In Arab Gulf Countries, the burden has increased exponentially over the past five decades due to rapid economic growth and urbanization. In the United Arab Emirates (UAE), chronic diseases are the leading cause of mortality and economic burden, hence, there is need to explore their patterns for targeted interventions. Studies among university students in Europe and the United States show chronic diseases prevalence ranging from 16.5% to 30.0%, respectively. To our knowledge, this is the first study in the Gulf region to assess multiple chronic diseases among university students. Our study describes the prevalence and patterns of multiple chronic diseases among UAE University (UAEU) students. Methods We conducted a descriptive cross-sectional study among UAEU students ≥18years from July to October 2021. Online questionnaire was used to collect data. Self-reported chronic diseases were described and compared between male and female students using chi-square and t tests. Other students’ characteristics were also explored. All analyses were conducted using STATA statistical software. Results 902 students participated in the study with mean age of 21.9±5.2yrs. 79.8% were females. 80.7% were undergraduates. The prevalence of self-reported chronic diseases was 23.0%. Obesity, Diabetes and Asthma/Allergies were the commonest (12.5%, 4.2% & 3.2%, respectively). 34.8% of the students were either overweight or obese. Overall chronic disease prevalence was similar between males and females [27.5% vs 21.8%, 0.104] though it was significantly higher among postgraduates, students who are older, married and have family history of diabetes. 4.7% of the students reported 2 or more chronic diseases. Conclusions Our study showed that more than 1 in 5 of the students reported at least one chronic disease. This shows the need for proactive chronic disease screening and prevention programs to meet the health needs of the students. Key messages • Prevalence of chronic diseases (Diabetes, Prediabetes, Obesity, Hypertension, Asthma/Allergies, Lipid disorders, Thyroid disorders, GI disorders, and CVDs) was high among the university students. • Universities should commit to researching students’ health and creating targeted health policies and interventions, as chronic diseases have direct and indirect negative impact on students’ education.

Gestational diabetes mellitus (GDM) burden is burgeoning globally. Correct knowledge about GDM among young people is paramount for timely prevention. This study assesses GDM knowledge and identifies factors associated with it among United Arab Emirates (UAE) University students. A validated self-administered questionnaire collected data from the university students. We analyzed the data for GDM knowledge status (ever heard of GDM) and GDM knowledge levels (poor, fair, and good) and conducted ordinal logistic regressions to assess for associated factors. A total of 735 students were surveyed with a mean age of 21.0 years. Of these, 72.8% had heard of GDM, and 52.9% of males versus 20.3% of female students had never heard of the condition before. Higher age (p = 0.019) and being a postgraduate student (p = 0.026) were associated with higher GDM knowledge status in males. GDM knowledge level analysis showed that 24.0%, 58.5%, and 17.5% had poor, fair, and good knowledge. The mean GDM-knowledge score was 6.3 ± 2.4 (out of 12). Being married [aOR-1.82 (95%CI 1.10–3.03)] and knowing someone who had GDM [aOR-1.78 (95%CI 1.23–2.60)] were independently associated with higher GDM knowledge levels among students. Students’ primary source of GDM knowledge was family/friends. There is an observed knowledge gap related to GDM among the students, especially males. This study urges the need to accelerate targeted GDM awareness campaigns among university students and the general population in the UAE.
