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 MassIndex 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 MassIndex, 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 MassIndex 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. [ABSTRACT FROM AUTHOR]

Objective To determine the preferred means by which participants in a study of cardiac rehabilitation wish to be informed of the study’s results. Design Postal questionnaire survey of participants in a randomized controlled trial. Setting Cornwall, southwest England. Participants Patients recruited to the Cornwall Heart Attack Rehabilitation Management Study (CHARMS). Method Participants recruited to CHARMS who were alive 3 years and 9 months after the trial was completed were contacted by letter and invited to return a reply slip with four short questions indicating how they would prefer to be informed about the published results of the study. Results In March 2008, 191/230 participants originally recruited to CHARMS were still alive. General practitioners deemed 166/191 (88%) survivors medically appropriate to be contacted through a postal survey, and 154/166 (93%) participants responded to the invitation to participate in the follow-up survey. 86% (143/166) of participants indicated that they wished to be informed about the results: 115 (80%) of these elected to receive information by letter and 25 (18%) of these preferred to attend a meeting. Men older than 65 years predominated in this latter group. Women respondents preferred to receive the study results by letter; none preferred communication by email or the web. Conclusion Survivors of acute myocardial infarction who participated in a RCT of cardiac rehabilitation wanted to receive a summary of the aggregate study results. Participants had preferences regarding how they would wish to be informed about the results of the study. Most participants preferred to be informed by letter or email, but some preferred the interaction of a group or a meeting. [ABSTRACT FROM AUTHOR]
