Long-Term Effects of the COVID-19 Pandemic on Eating Behaviors and Lifestyle in Families with School-Age Children in Rosario, Argentina

COVID-19 disrupted daily routines, altering eating patterns. However, it could encourage individuals to adopt healthier behaviors. While extensive research documented changes in dietary behaviors during the COVID-19 lockdown, few studies explored whether they persisted over time. This study aimed to identify the long-term effects of the pandemic on lifestyle and eating behaviors of families from a private primary school in Funes County, Rosario, Argentina. A total of 51 families (192 individuals) completed an anonymous survey on food intake and perceived dietary and lifestyle changes since the pandemic began. Multiple correspondence analysis revealed increased consumption of fast/processed foods, larger portion sizes, and snacking linked to eating from boredom, stress, or tiredness. Increased home-cooked meals, physical activity, interest in healthy habits, and leisure time enjoyment were also found. Dietary analysis revealed that higher intake of fruits, vegetables, legumes, and water was inversely associated with consumption of refined grains, cold cuts, pastries, and sugary drinks. Boredom, stress, or tiredness led to unfavorable changes. Interest in health, changes in home routines, spending more time together, and preparing meals with family resulted in healthier behaviors that remained present at the time of this study.
