Abstract

Background: This paper is a follow-up study continuing the COVISTRESS network previous research regarding health-related determinants. 
Objective: The aim was to identify the main consequences of COVID-19 lockdown on Body Mass Index and Perceived Fragility, related to Physical Activity (PA), for different categories of populations, worldwide. 
Design: The study design included an online survey, during the first wave of COVID-19 lockdown, across different world regions. 
Setting and participants: The research was carried out on 10121 participants from 67 countries. The recruitment of participants was achieved using snowball sampling techniques via social networks, with no exclusion criteria other than social media access.
Main outcome measures: BMI, PA, Perceived Fragility and risk of getting infected items were analyzed. SPSS software, v20 was used. Significance was set at p < 0.05. 
Results: BMI significantly increased during lockdown. For youth and young adults (18–35 years), PA decreased by 31.25%, for adults (36-65 years) by 26.05% and for the elderly (over 65 years) by 30.27%. There was a high level of Perceived Fragility and risk of getting infected for female participants and the elderly. Correlations between BMI, Perceived Fragility and PA were identified.
Discussion and Conclusions: The research results extend and confirm evidence that the elderly are more likely to be at risk, by experiencing weight gain, physical inactivity and enhanced perceived fragility. As a consequence, populations need to counteract the constraints imposed by the lockdown by being physically active. 
Patient or Public Contribution: Participants filled in and further disseminated the questionnaire.
