The epidemiological transition has been characterized by demographic, societal and health changes in societies. Presuming that acute diseases, mostly of communicable etiology, are more important in terms of early-life mortality, whereas chronic diseases are responsible for a greater burden of disease throughout the life course, we attempt to develop an index to measure the stage of the epidemiological transition. Using Global Burden of Diseases, Risk Factors and Injuries (GBD) data available at https://vizhub.healthdata.org/gbd-compare/ on 04/04/2024 to calculate the Epidemiologic Transition Estimate (ETE) index as a ratio of YLD/YLL for the time period of 1990-2019. The values of the index ranged from 0.131 to 1.067 and 0.180 to 2.108 for males and females, respectively, across the 195 included countries. The transition process seems to be faster to females compared to males. The index shows consistently increasing values for five SDI-based country groups, with clear differences among the groups. Although more research and validation studies are needed despite all the uncertainties, the index seems to be robust to assess the progress in epidemiological transition. These findings can help to predict future social care and health system needs to address causes leading to YLD or YLL.

Dental students are the future leaders of oral health in their respective communities; therefore, their oral health-related attitudes and behaviours are of practical value for primary disease prevention. The present study aimed to evaluate oral health-related knowledge, attitudes, and behaviours of dental students in Arab countries and explore the potential sociodemographic predictors of their oral health outcomes. A multi-centre, cross-sectional study was conducted during the academic year 2019/2020 in three Arab countries: Lebanon, Syria, and Tunisia. The study used a validated Arabic version of the Hiroshima University Dental Behavioural Inventory (HU-DBI) composed of original twenty items that assess the level of oral health-related knowledge, attitudes, and behaviours, and four additional dichotomous items related to tobacco smoking, alcohol drinking, problematic internet use, and regular dental check-up The HU-DBI score ranges between 0 and 12. A total of 1430 students took part in this study, out of which 60.8% were females, 57.8% were enrolled in clinical years, 24.5% were tobacco smokers, 7.2% were alcohol drinkers, and 87% reported internet addiction. The mean HU-DBI score was 6.31 ± 1.84, with Lebanon having the highest score (6.67 ± 1.83), followed by Syria (6.38 ± 1.83) and Tunisia (6.05 ± 1.83). Clinical students (6.78 ± 1.70) had higher HU-DBI scores than their preclinical peers (5.97 ± 1.86). The year-over-year analysis revealed that dental public health and preventive dentistry courses had significantly and positively impacted the undergraduate students' knowledge, attitudes, and behaviours. The gender-based differences were not statistically significant, with a modest trend favouring males, especially oral health behaviours. Tobacco smoking, alcohol drinking, and problematic internet use were associated with lower HU-DBI scores. In the Arab world, the economic rank of the country where the dental students live/study was weakly correlated with the students' mean HU-DBI score.
