The aim of this study was to estimate dietary habits and dietary antioxidant intake in a Polish adult population in relation to socioeconomic status. The subjects (4774) were participants in the Polish National Multi-Centre Health Examination Survey (the WOBASZ II study) performed in 2013–2014. Socioeconomic status (SES) scores were calculated by multiplying ordinal numerical values assigned to consecutive categories of education level and monthly income per capita in a family. In the Polish adult population, a higher socioeconomic status was significantly associated with a better lifestyle (more physical activity and less smoking), a better health status (lower occurrence of overweight individuals and metabolic syndrome in both genders, and lower occurrence of central obesity, hypertension, and diabetes in women), and better dietary habits, including a higher intake of dietary antioxidants.
Abnormal body mass and related metabolic disorders may affect female reproductive health.To determine the prevalence of under- and overweight, and also related metabolic disorders, among women at procreative age in Warsaw.164 non-pregnant women at procreative age (20-49 years) living in Warsaw, who in 2011-2012 participated in the WAW-KARD cross-sectional study of the Warsaw population, assigned to 3 age groups: 20-29 years (n=17), 30-39 years (n=78) and 40-49 years (n=69).Under- and overweight, obesity and abdominal obesity was found in respectively 1.2%, 25%, 12.2% and 37.2% of the participants. Prevalence of excessive body mass tended to increase with age. Hypercholesterolemia was shown in 42.7% of the whole group and was particularly widespread in the oldest females (56.5%). Prevalence of low serum HDL-cholesterol levels (found in 13.4% of the whole group) tended to increase with age, on the borderline of statistical significance. The mean fasting glucose level was 5.0±0.4 mmol/l and tended to increase with age. Impaired fasting glucose concerned 7.7% and 10.6% of females in age groups of 30-39 and 40-49 years respectively, and diabetes 4.4% of females 40-49 years old. Prevalence of arterial hypertension and metabolic syndrome (MS) in the whole group was 10.4% and 7.3% respectively; prevalence of MS tended to increase with age, on the borderline of statistical significance.Overweight and obesity, especially of abdominal type, are prevalent in women at procreative age in Warsaw. Disturbances of lipid and glucose metabolism, as well as arterial hypertension and MS, are also frequent. Prevalence of many of them tended to increase with age. Some of the women exhibited diabetes.
Devastating consequences of COVID-19 disease enhanced the role of promoting prevention-focused practices. Among targeted efforts, diet is regarded as one of the potential factors which can affect immune function and optimal nutrition is postulated as the method of augmentation of people's viral resistance. As epidemiological evidence is scarce, the present study aimed to explore the association between dietary intake of total polyphenols, lignans and plant sterols and the abundance of immunomodulatory gut microbiota such as Enterococcus spp. and Escherichia coli and the risk of developing COVID-19 disease.Demographic data, dietary habits, physical activity as well as the composition of body and gut microbiota were analyzed in a sample of 95 young healthy individuals. Dietary polyphenol, lignan and plant sterol intakes have been retrieved based on the amount of food consumed by the participants, the phytochemical content was assessed in laboratory analysis and using available databases.For all investigated polyphenols and phytosterols, except campesterol, every unit increase in the tertile of intake category was associated with a decrease in the odds of contracting COVID-19. The risk reduction ranged from several dozen percent to 70 %, depending on the individual plant-based chemical, and after controlling for basic covariates it was statistically significant for secoisolariciresinol (OR = 0.28, 95% CI: 0.11-0.61), total phytosterols (OR = 0.47, 95% CI: 0.22-0.95) and for stigmasterols (OR = 0.34, 95% CI: 0.14-0.72). We found an inverse association between increased β-sitosterol intake and phytosterols in total and the occurrence of Escherichia coli in stool samples outside reference values, with 72% (OR = 0.28, 95% CI: 0.08-0.86) and 66% (OR = 0.34, 95% CI: 0.10-1.08) reduced odds of abnormal level of bacteria for the highest compared with the lowest tertile of phytochemical consumption. Additionally, there was a trend of more frequent presence of Enterococcus spp. at relevant level in people with a higher intake of lariciresinol.The beneficial effects of polyphenols and phytosterols should be emphasized and these plant-based compounds should be regarded in the context of their utility as antiviral agents preventing influenza-type infections.
INTRODUCTION There are limited data on the current prevalence of overweight and obesity as well as its changes with time in Poland. OBJECTIVES The aim of the study was to assess the prevalence of general and abdominal obesity and overweight in Polish adults in the years 2013-2014, and to compare it with the prevalence in the years 2003-2005. PATIENTS AND METHODS The study was conducted in 2 independent, representative samples of the Polish population, comprising 14 537 persons (aged 20-74 years) examined in the years 2003-2005 and 6164 persons (aged ≥20 years) examined in the years 2013-2014. Anthropometric measurements were done by trained nurses. RESULTS In the years 2013-2014, the age-standardized prevalence of obesity (body mass index [BMI] ≥30 kg/m2) was 24.4% in men and 25.0% in women. The prevalence of overweight (BMI, 25.0-29.9 kg/m2) was 43.2% in men and 30.5% in women. Abdominal obesity (waist circumference ≥102 cm in men or ≥88 cm in women) was noted in 32.2% of men and 45.7% of women. Abdominal overweight (waist circumference, 94-101.9 cm in men or 80-87.9 cm in women) was present in 27.2% of men and 21.7% of women. Since the years 2003-2005, the distribution of body mass according to the BMI category had shifted to higher values, and an increase in the prevalence of obesity was observed in men. The percentage of adults with normal waist circumference decreased significantly in both sexes. CONCLUSIONS Every fourth inhabitant of Poland is obese, and during the last decade, the prevalence of obesity has increased, particularly in men. Abdominal obesity is observed in every third man and nearly every second woman, and an excess of abdominal fat has increased in both sexes.
It seems that one of the factors affecting the way of nutrition in Poland was the dietary habits of countries that in the late 18th century made partitions, ie. Russia, Prussia and Austria. Therefore, nutrition models in the areas of individual partitions have undergone significant changes.The aim of the study was to check whether after 85 years after regaining independence there were still differences in the way of feeding indigenous inhabitants of areas previously under Austrian, Prussian and Russian annexation.The data collected during the WOBASZ survey carried out in the years 2003-2005 were used for the analysis.The greatest differences in the way of feeding were found in the area that was previously under the rule of Prussia. The nutrition model was still largely reminiscent of typical German cuisine. There was a large consumption of sausages and spreads, and small vegetables and fruit. Nutrition models in other areas were less characteristic.The way of feeding indigenous people living in areas that were once partitions of Poland is still diverse and similar to the cuisine of the occupying country.
Dietary cholesterol has been suggested to increase the risk of cardiovascular disease (CVD). Phytosterols, present in food or phytosterol-enriched products, can reduce cholesterol available for absorption. The present study aimed to investigate the association between habitual intake of total and individual plant sterols (β-sitosterol, campesterol, and stigmasterol) or a diet combined with phytosterol-enriched products and CVD in a cross-section of Polish adults, participants of the Multicenter National Health Survey II (WOBASZ II). Among men (n = 2554), median intakes of plant sterols in terciles ranged between 183–456 mg/d and among women (n = 3136), 146–350 mg/d in terciles. The intake of phytosterols, when consumed with food containing phytosterols, including margarine, ranged between 184–459 mg/d for men and 147–352 mg/d for women. Among both men and women, beta-sitosterol intake predominated. Plant sterol intake was lower among both men and women with CVD (p = 0.016) compared to those without CVD. Diet quality, as measured by the Healthy Diet Index (HDI), was significantly higher in the third tercile of plant sterol intake for both men and women and the entire study group (p < 0.0001). This study suggests that habitual dietary intake of plant sterols may be associated with a lower chance of developing CVD, particularly in men.
Background: There has been an increasing global prevalence of depression and other psychiatric diseases in recent years. Perceived stress has been proven to be associated with psychiatric and somatic symptoms. Some animal and human studies have suggested that consuming foods abundant in lignans and phytosterols may be associated with lower levels of stress, depression, and anxiety. Still, the evidence is not yet strong enough to draw firm conclusions. Thus, we investigated the association between dietary intake of these phytochemicals and the level of stress experienced by adult individuals. Methods: Diet was assessed using self-reported 7-day dietary records. The intakes of lignans and phytosterols were estimated using databases with their content in various food products. The Perceived Stress Scale (PSS) was implemented to measure the level of perceived stress. A logistic regression analysis was used to test for associations. Results: The odds of elevated PSS were negatively associated with dietary intake of total phytosterols, stigmasterol, and β-sitosterol, with evidence of a decreasing trend across tertiles of phytochemicals. The analysis for doubling the intake reinforced the aforementioned relationships and found protective effects against PSS for total lignans, pinoresinol, and campesterol. Conclusions: Habitual inclusion of lignans and phytosterols in the diet may play a role in psychological health. To address the global outbreak of depression and other mental health issues triggered by stress, it is important to take a holistic approach. There is a need to develop effective strategies for prevention and treatment, among which certain dietary interventions such as consumption of products abundant in lignans and phytosterols may play a substantial role.
