Associations between Changes in Food Acquisition Behaviors, Dietary Intake, and Bodyweight during the COVID-19 Pandemic among Low-Income Parents in California

COVID-19 disrupted food access, potentially increasing nutritional risk and health inequities. This study aimed to describe and assess associations between changes in food/meal acquisition behaviors and relative changes in dietary intake and bodyweight from before to during the pandemic. Low-income parents (n = 1090) reported these changes by online survey in April-August 2021. Associations were assessed by multinomial logistic regression. Compared to those with no change, those who decreased supermarket shopping had greater odds of decreased fruit and vegetable (FV; OR[95%CI] = 2.4[1.4-4.1]) and increased salty snack intakes (OR[95%CI] = 1.7[1.0-2.8]). Those who decreased farmer's market shopping had greater odds of decreased FV intake (OR[95%CI] = 1.8[1.0-3.1]), increased bodyweight (OR[95%CI] = 1.7[1.1-2.6]), and increased SSB (OR[95%CI] = 1.9[1.1-3.2]) and sweets intakes (OR[95%CI] = 1.8[1.1-2.9]). Those who increased online food ordering had greater odds of increased sweets (OR[95%CI] = 1.7[1.1-2.8]), salty snacks (OR[95%CI] = 1.9[1.2-3.2]), and fast food (OR[95%CI] = 2.0[1.2-3.5]) intakes and bodyweight (OR[95%CI] = 1.8[1.1-2.9]). Those who increased healthy meal preparation had greater odds of increased FV intake (OR[95%CI] = 4.0[2.5-6.5]), decreased SSB (OR[95%CI] = 3.7[2.3-6.0]), sweets (OR[95%CI] = 2.7[1.6-4.4]), salty snacks (OR[95%CI] = 3.0[1.8-5]) and fast food intakes (OR[95%CI] = 2.8[1.7-4.6]) and bodyweight (OR[95%CI] = 2.2[1.2-4.0]). Interventions to address the potentially negative impacts of online food/meal shopping and support healthy home cooking may be needed to improve nutrition-related outcomes and reduce health disparities in the aftermath of the current pandemic and during future emergencies requiring similar restrictions.
