- Resumen: The association between food access and children's diet quality has been documented mainly from its external dimension (e.g., availability, prices, food properties, and marketing). However, existing research has underscored that the external food environment cannot fully account for variations in children's diet quality, even amid the COVID-19 lockdown. It is increasingly evident that elements within the domestic food environment also play a crucial role in shaping this relationship. Specifically, gender roles influence how food is procured and consumed, along with challenges related to time constraints. This study explores the influence of the domestic time-gender axis and household dynamics in food access and children's dietary quality in 14 female-headed households in Santiago, Chile, during the COVID-19 lockdown. Employing a photo-elicitation exercise, we engaged with families residing in the same urban neighborhood but exhibiting varying levels of dietary quality among their children. Our analysis utilized a framework incorporating both socio-ecological food environment and gender theories. Our findings show that within these households, only one unit of "person-time" was available to address all food and caregiving tasks. Due to an unequal gender system, this limited time allocation was disproportionately absorbed by women, who were already burdened with multiple responsibilities. The lack of time favors the consumption of ultra-processed foods and hinders the intake of fresh foods. Other associated intrahousehold dynamics, such as children's fussiness and special diets, accentuates these time scarcity consequences. These difficulties were further exacerbated by strategies adopted in response to the COVID-19 lockdown, however, in families where food-related responsibilities were shared more equitably the lockdown was less disrupting. These results indicate that on top of external food environment policies, comprehensive gender-transformative policies that include food socialization processes are needed to promote healthier diets among all.
