Dietary Choices and Habits during COVID-19 Lockdown: Experience from Poland

TLDR

The COVID‑19 pandemic prompted worldwide lockdowns and strict social distancing, affecting billions of people and altering daily life. The study aimed to evaluate how nutritional and consumer habits changed among adult Poles during the nationwide quarantine. Researchers performed a cross‑sectional online survey of 1,097 adults during the lockdown. During lockdown, 43 % ate more, 52 % snacked more, nearly 30 % gained an average of 3.0 kg, 18 % lost weight, overweight/obese and older adults gained weight more often, underweight individuals lost weight, higher BMI correlated with lower fruit/vegetable intake and higher meat/dairy/fast‑food consumption, 14.6 % increased alcohol intake (especially among alcohol addicts), and over 45 % of smokers increased smoking frequency.

Abstract

The outbreak of coronavirus disease (COVID-19) in late December 2019 in China, which later developed into a pandemic, has forced different countries to implement strict sanitary regimes and social distancing measures. Globally, at least four billion people were under lockdown, working remotely, homeschooling children, and facing challenges coping with quarantine and the stressful events. The present cross-sectional online survey of adult Poles (n = 1097), conducted during a nationwide quarantine, aimed to assess whether nutritional and consumer habits have been affected under these conditions. Over 43.0% and nearly 52% reported eating and snacking more, respectively, and these tendencies were more frequent in overweight and obese individuals. Almost 30% and over 18% experienced weight gain (mean ± SD 3.0 ± 1.6 kg) and loss (−2.9 ± 1.5 kg), respectively. Overweight, obese, and older subjects (aged 36–45 and >45) tended to gain weight more frequently, whereas those with underweight tended to lose it further. Increased BMI was associated with less frequent consumption of vegetables, fruit, and legumes during quarantine, and higher adherence to meat, dairy, and fast-foods. An increase in alcohol consumption was seen in 14.6%, with a higher tendency to drink more found among alcohol addicts. Over 45% of smokers experienced a rise in smoking frequency during the quarantine. The study highlights that lockdown imposed to contain an infectious agent may affect eating behaviors and dietary habits, and advocates for organized nutritional support during future epidemic-related quarantines, particularly for the most vulnerable groups, including overweight and obese subjects.
