Diet and selected elements of lifestyle in the Polish population before and during the COVID-19 pandemic - a population study.

INTRODUCTION AND OBJECTIVE: The COVID-19 pandemic led to the introduction of sanitary restrictions in many countries which necessitated numerous lifestyle changes, especially in the diet. The study aimed to compare the diet and selected lifestyle elements in the Polish population during the COVID-19 pandemic. MATERIAL AND METHODS: The study group consisted of 964 individuals: 482 before the COVID-19 pandemic (composed using the Propensity Score Matching method) and 482 during the pandemic. The National Health Programme 2017-2020 results were used. RESULTS: During the pandemic increased, e.g. the intake of: total lipids (78.4 g vs. 83 g; p<0.035), saturated fatty acids (SFA) (30.4 g vs. 32.3 g; p=0.01), sucrose (56.5 g vs. 64.6 g; p=0.0001), calcium (602.5 mg vs. 666.6 mg; p=0.004), and folate (261.6 mcg vs. 284.7 mcg; p=0.003). When nutrient densities of pre-Covid-19 and COVID-19 diets were compared, some differences were noted; per 1,000 kcal the amounts decreased of plant protein (13.7 g vs. 13.1 g; p=0.001), carbohydrates (130.8 g vs. 128.0 g; p=0.021), fibre (9.1 g vs. 8.4 g; p=0.000), sodium (1,968.6 mg vs. 1,824.2 mg; p=0.000); while the amounts increased of total lipids (35.9 g vs. 37.0 g; p=0.001), SFA (14.1 g vs. 14.7 g; p=0.003), and sucrose (26.4 g vs. 28.4 g; p=0.001). The COVID-19 pandemic had no effect on alcohol consumption, the number of smokers increased (from 131 to 169), sleep duration during weekdays, and the number of persons with low physical activity (182 vs. 245; p<0.001). CONCLUSIONS: Numerous unfavourable changes occurred in the diet and lifestyle during the COVID-19 pandemic, which may contribute to the exacerbation of health problems in the future. Nutrient density in the diet combined with well-designed consumer education may underlie the development of diet recommendations.

The Influence of Obesity on Nutrition and Physical Activity during COVID-19 Pandemic: A Case-Control Study.

Obesity is one of the important risk factors for a severe course of COVID-19. Maintaining a healthy body weight through diet and physical activity is a reasonable approach to preventing a SARS-CoV-2 infection or in alleviating its course. The goal of the study was to determine the influence of obesity on nutrition and physical activity during the COVID-19 pandemic. A total of 964 respondents, including 227 individuals with a body mass index (BMI) ≥30 kg/m2 were evaluated in this study. In the case of 482 respondents, including 105 individuals (21.8%) with BMI ≥ 30 kg/m2, the data were collected during the pandemic period from 1 June to 31 August 2020. The remaining 482 individuals were the "pre-pandemic" group, selected via propensity score matching (PSM) out of the 723 National Health Program study participants whose data was collected in 2017-2019. The evaluated dietary health factors were quantitatively similar in patients with BMI of either <30 kg/m2 or ≥30 kg/m2 and showed no significant changes during the pandemic. The diets of those who suffered from obesity prior to the pandemic showed the evaluated unhealthy nutritional factors to be less pronounced in comparison with those of individuals with BMI < 30 kg/m2. During the pandemic, the BMI ≥ 30 kg/m2 group showed a significant increase in the overall calorie intake (by 319 kcal; p = 0.001) and an increased consumption of total carbohydrates 299.3 ± 83.8 vs. 252.0 ± 101.5; p = 0.000), sucrose (51.7 ± 30.0 vs. 71.6 ± 49.9; p = 0.000), plant protein (26.3 ± 12.1 vs. 29.3 ± 8.3; p = 0.040), total fat (73.1 ± 42.6 vs. 84.9 ± 29.6; p = 0.011) and saturated fatty acids (29.5 ± 16.4 vs. 34.3 ± 13.9; p = 0.014) in comparison with the pre-pandemic period. The energy and nutritional value of the diets of BMI < 30 kg/m2 individuals did not change between the pre-pandemic and pandemic period. Before the pandemic, the level of leisure physical activity of the BMI ≥ 30 kg/m2 group was significantly lower than of those with BMI < 30 kg/m2. Such differences were not observed in the levels of physical activity at work or school. The pandemic did not alter the amount of physical activity either during leisure time or at work/school in individuals with BMI ≥ 30 kg/m2. However, respondents without obesity exercised significantly less during the pandemic than before. In conclusion, the pandemic altered the diets and levels of physical activity in the Polish population, with dietary changes observed in individuals with BMI ≥ 30 kg/m2 and changes in physical activity observed in those with BMI < 30 kg/m2.

A National Study of Nutrition and Nutritional Status of the Adult Polish Population in the Years 2017-2020 before and during the COVID-19 Pandemic-Design and Methods.

The paper presents the designs and methods of a cross-sectional study of two groups of randomly selected Polish inhabitants aged 19-64, and 65 and over, carried out as part of the National Health Program. The aim of the study was to illustrate the current health situation of the respondents in terms of nutrition and physical activity level. The quantitative and qualitative methods were used. The Computer Assisted Personal Interview technique was used. The dietary research was carried out through repeated interviews about the frequency of food consumption, and about what food had been consumed in the previous 24 h. In addition to the questionnaire studies, anthropometric data, blood pressure and the level of physical activity were measured. During the COVID-19 pandemic, some methods were modified according to hygiene rules. The Computer Assisted Telephone Interview technique was used to collect the data, and the anthropometric data were obtained via measurements made by the respondents themselves based on detailed instructions. The results will be used to present representative data for the Polish population, describing a wide range of eating behaviours and other lifestyle elements, food and nutrition knowledge, dietary supplement use, the occurrence of diet-related diseases, nutritional status and, in the seniors group, the risk of sarcopenia.

The Role of Resilience and Basic Hope in the Adherence to Dietary Recommendations in the Polish Population during the COVID-19 Pandemic.

(1) Background: The COVID-19 pandemic exerts a negative influence on dietary behaviors, which may lead to health deterioration. Dietary behaviors may be determined by psychological characteristics, such as basic hope and resilience, which facilitate the effective adjustment to new difficult conditions. The professional literature includes no research on the role of basic hope and resilience in the context of undertaken dietary behaviors in the situations of mental load associated with pandemics. The study aimed at the description of the dietary behaviors of individuals with various intensities of the discussed psychological characteristics (basic hope and resilience); (2) The observational cross-sectional online questionnaire study was conducted with the participation of 1082 adult Polish inhabitants. Three psychological scales were used: PSS-10, the Brief Resilient Coping Scale (BRCS) and BHI-12 questionnaire. The assessment of the adherence to dietary recommendations was performed with the present authors' Dietary Guidelines Adherence Index (DGA Index); (3) Results: The value of DGA Index was variable depending on the psychological profile of study participants. The highest adherence to the principles of appropriate nutrition was observed in individuals characterized by the ability to cope with difficult situations and those who quickly adapted to new changing circumstances. The DGA Index values became poorer with the deterioration of the coping ability as regards stress and mental load; (4) Conclusions: Nutritional education during pandemics should encompass the psychological profile of the patients. It requires the implementation of a different psychodietetic approach which will facilitate a more effective introduction of a well-balanced diet.
