Healthy lifestyles in pre-service teachers in Israel: the impact of academic institutions.

Purpose: This study examines the impact of academic institutions on changes to students' awareness and habits regarding a healthy lifestyle, specifically through nutrition and physical exercise, following the Covid-19 pandemic.

Design And Subjects: In May 2020, quantitative online questionnaires were completed by 266 pre-service teachers (83.5% female), aged 19-63, who were studying at an academic institution in Israel.

Setting: The questionnaire, which included health-related 15 items, as well as a number of demographic questions, was distributed social media, academic mailing lists, and the researchers' colleagues.

Methods: The respondents were asked to provide socio-demographic data and information regarding their health-related habits, such as smoking and exercising, at two timepoints: prior to the Covid-19 pandemic and during the first lockdown in Israel (March-May 2020).

Analysis: Statistical analysis included paired -tests, Wilcoxon and McNemar tests, Pearsons's correlations, and hierarchical regressions.

Results: The academic institution's promoting of a healthy lifestyle, as perceived by students, was found to contribute to the explained variance (EPV) of their maintaining a healthy lifestyle, prior to and during the Covid-19 pandemic ( = 9.4%,  < .001and  = 2.4%,  = 0.009, respectively), beyond the respondents' demographic characteristics. Moreover, correlations were found between the institution's promoting of a healthy lifestyle at both timepoints. Respondents who perceived their institution as promoting a healthy lifestyle prior to the pandemic maintained healthier lifestyles than their peers; healthier lifestyles were also maintained by respondents who were unmarried, non-smokers, more educated, and watched less television. Finally, the institution's promoting of a healthy lifestyle prior to the pandemic significantly contributed to the students' maintaining a healthy lifestyle and healthy nutrition during the pandemic.

Conclusion: The findings of this study highlight the impact of academic institutions on maintaining healthy lifestyles, even in times of crises and emergencies, thereby contributing to public health.
