Individuals with obesity experienced a 52% prevalence of weight gain during lockdown, driven by reduced physical activity and increased snacking, though longitudinal BMI changes were not statistically significant in pooled analyses.
For individuals with obesity, lockdown led to weight gain in more than half of cases, primarily due to less movement and more snacking. While average BMI didn't shift significantly in longitudinal studies, the individual risk is high. Focus on maintaining daily movement and managing snacking triggers, as the loss of structured activity is a major driver of weight gain.
The pooled prevalence of increased weight in obesity was 52% (95% CI[25,78], k = 4)... More than 50% of the individuals with obesity reported increased weight during lockdown, reduced levels of physical activity, and increased snacking.
Why this rating
Meta-analysis of 4 studies, high heterogeneity, and reliance on self-reported weight in many cases.
