Coming out of isolation: impacts of COVID-19 on physical activity, diet, mental well-being, and sleep over time.

Introduction: The COVID-19 pandemic lockdown significantly disrupted daily routines and impacted physical activity, diet, mental well-being, and sleep.

Methods: A mixed-methods study was conducted with 34 US participants who completed open-ended qualitative questions and quantitative assessments in May 2020 and May 2021.
