Impact of the COVID-19 pandemic on the changes in dietary habits, lifestyle and physical activity in the Slovak population.

Background: The COVID-19 pandemic caused by the coronavirus was accompanied by the emergence of various adverse conditions, as well as the deterioration of health from the point of view of chronic diseases, as well as lifestyle changes related to the preference of certain foods and changes in body weight due to the restriction of free movement. Objective: The objective of our survey was to assess the impact of the pandemic and lockdown on selected key lifestyle elements affecting the overall health status of the Slovak population and subsequently to evaluate subjectively assessed changes in the respondents' eating habits, daily routine, physical activity and body weight. Material and Methods: The research group consisted of 528 participants who took part in an online distributed questionnaire survey. Results: Respondents subjectively evaluated the change in lifestyle rather negatively. Up to 48.37% of men and 38.93% of women reported a change for the worse. Almost 59% of participants reported no change in their health, while almost a quarter reported a slight deterioration in their health. A change in eating habits for the worse was reported by 22.88% of men and 28.26% of women (p<0.05). Increased appetite during the lockdown was reported by 24.18% of men and 35.47% of women (p<0.05), more frequent overeating during the pandemic occurred in 30.07% of men and 38.13% of women. When evaluating the consumption of individual food commodities, the increased consumption of fresh fruit, fresh vegetables (p<0.01), homemade bread (p<0.05), homemade pastries (p<0.05) and dairy products (p<0.05) is very favourable. We also found a significant increase in the consumption of sweets (p<0.01) and coffee (p<0.001). When evaluating the sleep pattern, we noted an increase in sleep during the pandemic, as well as more time spent sitting. Over half of the respondents reported a change in body weight, in most cases it was an increase in both sexes. Conclusions: The results show that the pandemic and the restrictions during it caused changes not only in diet, but also in physical activity, daily routine and overall lifestyle. However, this is a very specific issue that needs to be assessed in a comprehensive and strictly personalized manner. The positive or negative impact of the pandemic on the health of the population will be the subject of research in the near future.

Modulation of Lipid Profile and Lipoprotein Subfractions in Overweight/Obese Women at Risk of Cardiovascular Diseases through the Consumption of Apple/Berry Juice.

Polyphenol-rich foods protect the cellular systems of the human body from oxidative damage, thereby reducing the risk of chronic diseases such as cardiovascular disease (CVD). We investigated the effect of phenolic-rich apple/berry juice (chokeberry, blueberry, and cranberry) on lipidemic profiles in overweight/obese women. The 6 week single-arm pre-post intervention study involved 20 women (mean age 52.95 ± 5.8 years, body mass index ≥25 kg/m2, and ≥1 CVD risk factors) consuming 300 mL/day of the apple/berry juice. Lipid profile, low-density lipoprotein (LDL) subfractions assessed using Lipoprint® electrophoresis, and other parameters related to cardiovascular risk (C-reactive protein, glucose, blood pressure) were analyzed before and again after the intervention in the monitored group of women. High-density lipoprotein cholesterol (HDL-C) increased from 1.30 ± 0.29 to 1.55 ± 0.32, magnesium from 0.85 ± 0.03 to 0.90 ± 0.05, and total antioxidant status from 1.68 ± 0.08 to 1.81 ± 0.10. The LDL/HDL ratio significantly decreased from 3.40 ± 0.99 to 2.66 ± 0.63 mmol/L, and the glucose from 5.50 ± 0.72 to 5.24 ± 0.74 mmol/L. However, the hs-CRP did not change significantly. Women with atherogenic subfractions LDL3-7 at baseline (n = 6) showed a significant reduction from 0.45 ± 0.19 to 0.09 ± 0.07 mmol/L. Overweight/obese women may benefit from apple/berry juice as part of a healthy lifestyle to improve their lipid profile, and thus, contribute to cardiovascular health.

The Use of Different Anthropometric Indices to Assess the Body Composition of Young Women in Relation to the Incidence of Obesity, Sarcopenia and the Premature Mortality Risk.

The objective of the study was to evaluate the stratification of young women based on the assessment of body composition according to several currently recommended anthropometric indices and parameters, as well as the presence of obesity, sarcopenic obesity and the risk of premature death. Three hundred and three young Caucasian women aged 18-25 years were included in the cross-sectional observational study. For the purposes of the study, we used the bioelectrical impedance method and applied the obtained data to calculate indices defining obesity, sarcopenic obesity and premature mortality risk (ABSI z-score). We found significant differences between indicators of total and abdominal obesity when determining the rate of risk of premature death and diagnosis of obesity. Our results also suggest that FMI and FM/FFM indices correlate excellently with fat mass and visceral adipose tissue, better than BMI. Even in the case of abdominal obesity, FMI appears to correlate relatively strongly, more so than BMI. The results of the study support the opinion that in the assessment of body composition and health status, the presence of obesity (sarcopenic obesity) and the risk of premature death, anthropometric parameters and indices focusing not only on body weight (BMI, ABSI), but also on the proportionality and distribution of fat (WC, WHR, WHtR, VFA) and muscle tissue (FFMI, SMMI, FM/FFM ratio) should be used.
