Background The amount of research about orthorexic attitudes and behaviours has increased in the last five years, but is still mainly based on descriptive and anecdotal data, yielding a variety of prevalence data and inconsistent results. The interplay between socio-cultural context and orthorexia has been poorly investigated and is still far from being understood. Method Multicentre, cross-sectional study involving Italian ( N = 216), Polish ( N = 206) and Spanish ( N = 242) university students, assessed through a protocol including informed consent, socio-demographic and anamnestic data sheet and self-administered questionnaires (ORTO-15, Eating Attitudes Test- 26 [EAT-26], Temperament and Character Inventory [TCI]). Results Higher prevalence of orthorexia (as described by the ORTO-15 cutoff) was found in Poland. Female gender, Body Mass Index (BMI), current Eating Disorder, dieting, EAT-26 score ≥ 20 and low/medium Persistence were associated with orthorexia in the whole sample. The cross-cultural comparison showed several differences among the three subgroups of students. Conclusions The associations found between orthorexic attitudes, self-reported current eating disorder, BMI and adherence to a dieting need to be supported by further research. The differences among students from the three countries seem to suggest a possible rolve for cultural elements in the construct of orthorexia.

The 2019-nCOVID pandemic as a public health emergency has faced healthcare systems with unprecedented challenges. Our study aimed to focus on the mental health impact of the 2019-nCOVID pandemic on healthcare workers (HCWs) from North-Eastern Piedmont, Italy. For this purpose, we performed an online survey which was e-mailed to HCWs at the end of the first peak of the pandemic. We involved both frontline and not-frontline HCWs, employed in the hospital or in healthcare services outside the hospital. The primary outcome of our research was the assessment of burnout, while secondary outcomes included the investigation of anxiety, depression, and post-traumatic stress symptoms. We observed higher levels of burnout (especially in the Depersonalization and Personal Accomplishment dimensions), in females, in HCWs aged <30 years, in those exposed to changes in their daily and family habits, in those who had to change their duties at work and in residents in training. In our HCWs sample we found lower levels of anxiety and depression than those reported in the literature. The problematic levels of burnout and adverse psychological outcomes observed during the pandemic cannot be underestimated. Given the recurrence in autumn 2020 of a new pandemic peak, which has once again put a strain on the health system and HCWs, it is supported the importance of a careful assessment of HCWs' mental health, and of the possible risk and protective factors both in the work environment and in the extra-work one.
