Physical activity, sleep, dietary habits, and screen time in Bogotá’s children post-pandemic lockdown: a mixed-methods study

Purpose This study explored how Bogotá’s children reconfigured their post-lockdown routines as part of their lived experience after returning to in-person activities.Methods A mixed-methods design was applied to capture behavioral patterns and their meanings. Quantitatively, 217 children aged 8–12 years attending pediatric clinics (Oct 2022–Sep 2023) completed validated questionnaires assessing physical activity, sleep, diet, and screen exposure. Qualitatively, semi-structured interviews were conducted with 15 children selected through purposive sampling to deepen insight into their daily routines and perceptions. Quantitative data were analyzed descriptively and by sex, while thematic analysis of interviews provided contextual interpretation. Integration occurred through a narrative weaving approach.Results Quantitative findings indicated moderate physical activity (66% met ≥ 3 days/week), widespread sleep disturbances (49.7%), recreational screen use (median= 6 hours/day), and poor dietary intake (>90% consumed fewer than two vegetable servings daily). Narratives revealed that play was often replaced by structured adult-imposed activities, screen time served as both emotional refuge and behavioral reward, and sleep was self-managed through distractions such as eating or watching TV. Children viewed these habits as normal despite feelings of fatigue, frustration, and a longing for autonomy.Conclusion Children's post-lockdown routines reflect adaptation rather than behavioral lapses, requiring interventions focus on emotional regulation, time balance, quality rest, and active play (not merely a return to pre-pandemic norms).
