Objective This study aimed to describe changes in families’ home food environment and parent feeding practices, from before to during the coronavirus disease 2019 (COVID‐19) pandemic, and examine whether changes differed by food security status. Methods Parents (N = 584) in the US completed a single online survey, reporting on food security, home food availability, and feeding practices both retrospectively (considering before COVID‐19) and currently (during COVID‐19). χ2 and univariate regressions examined associations by food security status. Results The percent of families reporting very low food security increased by 20% from before to during COVID‐19 (P < 0.01). About one‐third of families increased the amount of high‐calorie snack foods, desserts/sweets, and fresh foods in their home; 47% increased nonperishable processed foods. Concern about child overweight increased during COVID‐19, with a greater increase for food‐insecure versus food‐secure parents (P < 0.01). Use of restriction, pressure to eat, and monitoring increased, with a greater increase in pressure to eat for parents with food insecurity compared with food‐secure parents (P < 0.05). Conclusions During COVID‐19, increases in very low food security and changes in the home food environment and parent feeding practices were observed. Results highlight the need to address negative impacts of COVID‐19 on children’s obesity risk, particularly among those facing health disparities.

Background: The Coronavirus Disease 2019 (COVID-19) pandemic has caused numerous unexpected challenges for many families, and these long-lasting demands likely contribute to higher stress for parents. The aim of this study was to describe changes in parent stress longitudinally from before (retrospective) to two timepoints during COVID-19. Stressors that influenced parenting and strategies to manage parenting difficulties at each timepoint during COVID-19 are also described.Methods: Parents (N = 433; 95% female) in the US with &gt;1 child aged 5–18 years completed an online survey in May 2020 (T1; at the peak of stay-at-home mandates) and in September 2020 (T2; children's return to school). Surveys included the 10-item Perceived Stress Scale (PSS) and questions on parenting-specific stress, stressors that influenced parenting, and strategies to manage parenting difficulties during COVID-19. Retrospective report of pre-COVID-19 stress was assessed at T1; current stress was assessed at T1 and T2. Repeated measures analysis of variance examined changes in stress over time.Results: Parent's stress increased from before COVID-19 to T1 (PSS score: 16.3 ± 5.7 to 22.0 ± 6.4, respectively; p &lt; 0.01), and decreased by T2 (19.2 ± 6.0), but remained elevated above pre-COVID-19 values (p &lt; 0.01). Most parents (71.1%) reported an increase parenting-specific stress from before COVID-19 to T1, which continued to increase for 55% of parents at T2. Common stressors that impacted parenting during COVID-19 were changes in children's routines, worry about COVID-19, and online schooling demands. Common strategies parents used to manage parenting difficulties included doing family activities together, keeping in touch with family/friends virtually, and keeping children on daily routines.Conclusions: Parent stress increased substantially during COVID-19 and has not returned to pre-COVID-19 levels, suggesting the need for enhanced mental health resources and supports. Public health interventions should address parenting-specific stressors and effective strategies for managing parenting difficulties to mitigate their deleterious impact.
