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 10 121 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
Body Mass
Index
,
Physical Activity
,
Perceived Fragility and risk of getting infected
items were analysed. SPSS software, v20, was used. Significance was set at
P
< .05.
Results
Body Mass
Index
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.
