Consumption of selected food products by adults representing various body mass categories, during Covid-19 lockdown in Poland.

Objectives: The study aimed to assess consumption of selected food products by adults with a range of body mass before and during the outbreak of the Covid-19 pandemic as well as identify factors impacting the consumption of selected foods.

Methods: The study was conducted in a group of 690 subjects during the most severe lockdown due to Covid-19 in Poland ([Formula: see text] = 23 years of age). The dietary assessment was carried out by means of an online survey based on the Food Frequency Questionnaire (FFQ-6). The respondents were asked to provide two answers to each question, one covering a 7-day period before the lockdown and one related to a 7-day period during the lockdown.

Results: During lockdown in the study group there was increase in consumption of sweets and snacks (p = 0.010), grain products (p = 0.050), fat (p = 0.007) as well as alcohol (p < 0.001). During the lockdown respondents with normal BMI increased consumption of sweets and snacks (p = 0.011), dairy products and eggs (p = 0.034), grain products (p = 0.029) and alcohol (p = 0.00). The group of overweight respondents was found to consume significantly more alcohol (p = 0.022), while those with obesity tended to consume more meat (p = 0.002), fish (p < 0.001) and lower amounts of dairy products (p = 0.003). The factors which affected intake of selected food products include age, smoking, place of residence, obesity and education.

Conclusions: Covid-19 pandemic is significantly related to the change in the frequency of intake of selected products by all adults, irrespective of their BMI. The adverse changes were particularly observed in respondents with overweight and obesity.
