Health promoting behaviour of medical versus non-medical students during COVID-19 pandemic: results from the COLA cross-sectional study.

To investigate the COVID-19 pandemic related alteration of health promoting behaviour during lockdown among medical students compared to other students.In this cross-sectional study, we enrolled 1940 Bavarian students. Participants were asked to complete an online questionnaire 3 weeks after lockdown implementation, evaluating their lifestyle behaviour focusing on self-reported and objectively assessed physical activity.1154 medical (59.5%) and 786 non-medical (40.5%) students were included (median age 22.0 [IQR, 20.0-25.0], 71.5% female). Physical activity decreased in both groups after lockdown implementation. During lockdown, medical students reported higher physical activity levels compared to non-medical students. This was corroborated by daily step count data assessed by wearables (median steps per day [IQR], 6979 [5218-9348] versus 6581 [4497-8491], p = 0.02). Smoking behaviour during lockdown did not differ between medical and non-medical students (increased in 11.8% vs 13.6%, decreased in 31.9% versus 36.9%).During the COVID-19 pandemic, alteration of lifestyle behaviour among medical students was significantly different compared to non-medical students. This result suggests that medical students are more concerned about health promoting behaviour even in crisis situations.

Altered alcohol consumption during COVID-19 pandemic lockdown.

BACKGROUND: Since the onset of the COVID-19 pandemic in December 2019, many countries around the world have imposed lockdown measures in order to reduce virus spread. Social isolation is known to have a significant psychological impact, potentially triggering alcohol misuse in adults. In our study, we aimed to investigate the effect of COVID-19 lockdown measures on alcohol consumption in adults in Bavaria. METHODS: In this cross-sectional study, we enrolled 2067 participants, with 1961 young adults (mean age 23.3 ± 4.1) and 106 mature adults (mean age 66.7 ± 9.7). Participants were asked to complete a standardized questionnaire, semi-quantitatively evaluating the alcohol drinking behaviour before and during the pandemic lockdown. RESULTS: After implementation of lockdown, the alteration of alcohol consumption was significantly different between young and mature adults (p <  0.001). Among young adults, 42% reported unchanged drinking behaviour compared to 76% in the mature adult group; 44% of young adults reported to drink less compared to only 7% of mature adults. An increase in alcohol consumption was only reported by 14% of young adults and 17% of mature adults. Interestingly, in the entire cohort, the change of alcohol intake was most pronounced among moderate drinkers (> 0 to < 5 drinks/week) in both age groups (p <  0.001). Ordinal logistic regression revealed female sex, low BMI and younger age to be associated with a decrease in number of self-reported drinks/week. CONCLUSION: The COVID-19 pandemic lockdown significantly affected alcohol drinking behaviour. Further studies exploring long-term effects on potential alcohol misuse and the relevance on public health are warranted. TRIAL REGISTRATION: The study was retrospectively registered at ClinicalTrials.gov ( NCT04361877 ) on April 24, 2020.

Altered nutrition behavior during COVID-19 pandemic lockdown in young adults.

PURPOSE: The COVID-19 pandemic and the implemented lockdown strongly impact on everyone's daily life. Stressful situations are known to alter eating habits and increase the risk for obesity. In our study, we aimed to investigate the effect of the lockdown measures on nutrition behavior among young adults. METHODS: In this cross-sectional study, we enrolled 1964 voluntary participants from Bavarian universities. All participants were asked to complete an online questionnaire, semi-quantitatively evaluating the amount and type of food before and during pandemic lockdown. Study subjects were inquired to give information about acquisition and food procurement. The primary outcome was the change in food amount, secondary outcomes included alterations of food composition and procurement. RESULTS: Our study cohort (mean age 23.3 ± 4.0 years, 28.5% male) had a mean body mass index of 22.1 ± 4.5 kg/m2. The overall food amount increased in 31.2% of participants (n = 610) during lockdown and decreased in 16.8% (n = 328). A multinominal regression model revealed that an increased food intake was less likely in male participants (OR, 0.7 [CI 0.6-0.9]) and more likely with increasing BMI (OR, 1.4 [CI 1.3-2.0]), increased sports activity (OR, 1.3 [CI 1.2-1.8]), augmented mental stress (OR 1.4 [1.1-1.7]), and an alteration of alcohol consumption (reduced alcohol amount, OR, 1.4 [CI 1.1-1.7], increased alcohol, OR, 1.9 [CI 1.4-2.5]). Increase in food intake was mainly triggered by consumption of bread (increased in 46.8%, n = 284) and confectionary (increased in 64.4%, n = 389). CONCLUSION: The COVID-19 pandemic lockdown significantly affected eating habits in young adults. Further investigation to evaluate long-term effects on weight change and comorbidities are warranted.

Mental health impairment triggered by the COVID-19 pandemic in a sample population of German students.

Due to the rapid spread of the COVID-19 pandemic, a lockdown including limitation of activity and restrictions of non-essential travel was imposed on March 21, 2020 in the State of Bavaria, Germany. The implementation of activity restrictions not only strongly affects the economy but will possibly also impact the mental and physical health status of the general population. Therefore, the present study aimed to explore psychological effects of the COVID-19 crisis on a sample of Bavarian students.In this cross-sectional study, we enrolled 1943 voluntary subjects from Bavarian universities. All subjects completed an online questionnaire asking for mental health stress, as well as potential factors, influencing the state of mental stress during pandemic lockdown. In our study cohort, 17.3% (n=336) of the students indicated that they experienced less mental stress through COVID-19 pandemic, while 39.6% (n=770) stated that they had an increased psychological burden. The bivariate analysis identified sex and the level of physical activity as potential risk factors for the level of mental stress during the COVID-19 pandemic. Further research is necessary to investigate specific symptoms of mental stress and the overall long-term impact on mental health.
