<p>Leisure time is a central aspect of child development and has been consistently associated with subjective well-being. However, there is little evidence in Chile regarding how different patterns of daily activities are organised and related to well-being in childhood. This study aimed to identify profiles of daily activities among Chilean children and examine differences in subjective well-being. Data from a sample of 868 boys and girls aged 10 and 11 were analysed, drawn from the Chilean sample of the third wave of the International Children’s Worlds study. The frequency of participation in various daily life activities, life satisfaction, satisfaction with time use, and positive and negative affect were assessed. Latent Profile Analysis identified three profiles: High Recreational Activity, High Overall Activity, and Low Activity. The results showed significant differences across all dimensions of subjective well-being. Children in the Low Activity profile had lower levels of positive affect, life satisfaction, and satisfaction with time use compared with those in the higher activity profiles. The negative affect was higher among children in the Low Activity profile compared with those in the High Recreational Activity. These findings suggest that not only the presence of activities, but also the diversity and active nature of leisure-time use are associated with children’s subjective well-being, highlighting the importance of promoting opportunities for active leisure in childhood</p>
