Microelements and vitamins are believed to have immunomodulatory effects. The aim of the study was to establish the role of antioxidants (vitamins A, E, D) and microelements such as copper (Cu), selenium (Se), and zinc (Zn) levels in allergic diseases in schoolchildren. The study uses a cohort of 80 children (40 with and 40 without allergy/asthma diagnosis) aged 9 to 12 years recruited for the Polish Mother and Child Cohort Study. At nine to twelve years old, the children were tested for microelement and vitamin content and health status (including skin-prick test and spirometry, urine cotinine level). Demographic data were collected from mothers by an allergist. The risk of asthma occurrence was found to be significantly related to the levels of Cu and Zn. The level of Cu was also particularly closely associated with allergic rhinitis and was indicated as a significant predictor of food allergy. The levels of Cu and Zn, and poor nutritional status in general, can influence the immune system and may be considered risk factors for developing asthma, allergic rhinitis and food allergy.

The study objective was to identify determinants of essential elements and vitamins intake, and microelements and vitamins concentration in blood among pregnant women from Poland. Based on the data from food frequency questionnaires and information about supplements taken (n = 1252), daily supply of six elements (calcium, magnesium, iron, zinc, copper, selenium) and nine vitamins (folate, vitamins A, E, C, B1, B2, B3, B6, B12) was calculated. Zinc, copper, selenium (n = 340), vitamin A and E (n = 358) concentration was determined in blood collected during pregnancy. Most of the women did not meet the demand for essential elements and vitamins with a diet. About 94% of the respondents declared supplements use. The women with higher education, indicating leisure-time, physical activity and multiparity had a higher chance of meeting the average demand for the majority of the analyzed nutrients. On the other hand, factors such as BMI &lt, 18.5kg/m2, a higher level of stress, and late first medical-care visit were associated with a lower chance of meeting the recommendations. Higher socio-economic status was a determinant of a higher selenium concentration in plasma (β = 3.1, 95%CI: 0.2–5.9), whereas BMI ≥ 25 kg/m2, and multiparity of a higher copper concentration in plasma (β = 0.2, 95%CI: 0.03-0.4, β = 0.2, 95%CI: 0.1–0.4). Higher plasma concentration of vitamin E was noted among women older than 30 years of age comparing to those who were 30 or younger (β = 1.5, 95%CI: 0.6–2.4). Although more studies are required, especially such based on laboratory measures, our results indicate target groups for dietary interventions during pregnancy for children’s optimal health and development.

As part of cardiovascular disease prevention, the performance of BMI determination, blood pressure measurement, biochemical tests, as well as a lifestyle-related risk assessment are recommended. The aim of this study was to evaluate the correlates of blood pressure and cholesterol level testing among a socially-disadvantaged population in Poland. This cross-sectional study was performed between 2015 and 2016 among 1710 beneficiaries of government welfare assistance. Face-to-face interviews conducted by trained staff at each participant&rsquo, s place of residence allowed for completion of questionnaires that covered socio-demographic, health and lifestyle-related information. Sixty-five percent of the participants declared a blood pressure and 27% of them cholesterol level testing at least once within the year proceeding the study. A higher chance of having blood pressure testing was observed among the women (OR = 1.5, p = 0.002) and people with high blood pressure (OR = 3.9, p &lt, 0.001). The women (OR = 1.4, p = 0.04) and older people (OR = 1.9, p = 0.02, OR = 2.6, 0.001, OR = 2.7, p = 0.002, for the following age groups: 30-39, 40-49, 50-59 years respectively), the respondents who declared health problems such as heart attack (OR = 3.0, p = 0.04), high blood pressure (OR = 2.3, 0.001) and type 2 diabetes (OR = 3.3, p = 0.004) and those with a family history of chronic diseases (OR = 1.5, p = 0.03) had a higher chance of cholesterol level checking. Higher healthy lifestyle index, indicating that the study participants have followed almost all of the studied lifestyle-related recommendations, was a significant correlate of cholesterol level testing (OR = 1.7, p = 0.006). Actions that promote lifestyle changes, blood pressure, and cholesterol level testing should take into account the needs of the disadvantaged population and should especially target men, people with existing chronic diseases, and those with unfavorable lifestyle characteristics. With respect to the socially-disadvantaged population, the social assistance institutions and outpatient clinics are the best places to conduct activities promoting a healthy lifestyle. The most commonly applied strategies to promote lifestyle changes can cover risk assessment, increasing awareness, emotional support and encouragement, as well as a referral to specialists.

The goal of this cross-sectional survey was to assess the level of knowledge on harmful effects of environmental tobacco smoke (ETS) exposure and active smoking among socially-disadvantaged people in Poland. The study was conducted among 1817 respondents aged 18&ndash, 59 years, who used aid services from local social care institutions in Piotrkowski district. Majority of the participants were aware of the fact that smoking may cause serious diseases and lung cancer (92%). However, those percentages were lower for awareness of ETS and health risk (69.4%) and for awareness of smoking/ETS-associated risk of stroke and heart attack (57%, 68%). The male respondents and smokers had much higher odds of lacking knowledge that smoking causes serious diseases and lung cancer compared to the females (OR = 1.47 and OR = 1.86, p &lt, 0.05) and non-smokers (OR = 2.35 and OR = 2.31, 0.001). In addition, those with temporary jobs and the unemployed had a higher risk of lack of knowledge on smoking and lung cancer risk (OR = 2.14 and OR = 1.66, 0.05) as well as ETS and the risk of stroke (OR = 1.52 and OR = 1.51, 0.05) as compared to those with permanent jobs. The smokers who were aware of four health consequences of smoking indicated an intention to quit smoking within the next month more frequently when compared to those who did not have the knowledge on all of the analyzed harmful effects of tobacco use (19.7% vs. 13.1%, 0.05). There is a need to improve knowledge on the dangers associated with active and passive smoking among socially disadvantaged populations.

Epidemiological studies have suggested an association between maternal antioxidant levels during pregnancy and development of allergic diseases in their offspring. The aim of the study was to determine plasma vitamins A and E concentration in the 1st trimester of pregnancy, at delivery and in cord blood and to search for a relationship with allergy in up to 2-year-old children who were prenatally exposed or not exposed to tobacco smoke. The study participants included 252 mother-child pairs from Polish Mother and Child Cohort. Vitamin concentrations were measured using the HPLC-UV method, smoking status&mdash, as saliva cotinine level using the HPLC-MS/MS technique. Children&rsquo, s health status was assessed using a questionnaire and pediatricians/allergists examination. Cord plasma vitamin concentrations were significantly lower than their levels in maternal plasma in the 1sttrimester and at delivery (p &lt, 0.001). Significantly higher concentrations of vitamin E have been shown to occur during the 1st trimester of pregnancy in plasma of the women who have actively/passively smoked cigarettes compared to the non-smokers (p &lt, 0.02). Multivariate analysis with inclusion of a variety of confounding factors have not indicated any statistically significant associations between &beta, carotene, vitamins A and E and the risk of food allergy, atopic dermatitis and wheezing in their children up to 2 years of age. The interaction between smoking during pregnancy and vitamins levels on the risk of allergy was not statistically significant (p &lt, 0.4). The relationship between plasma concentration of vitamins A and E, and the risk of allergy in their young children has not been demonstrated.
