A total of 592 incident cases of colorectal cancer have been enrolled in a hospital-based case-control study. The comparison group included 765 controls chosen from the patients of the same hospital without history of cancer and admitted for treatment of nonneoplastic conditions. Interviews of both cases and controls were conducted in the hospital setting by trained interviewers. The median intake of fruits among cases was lower than in controls (9.5 vs. 11 servings/week) and the difference was statistically significant. Apples were the most frequent fruit consumed by the study participants and about 80% of variability in the total fruit consumption resulted from the intake of apples. We did not observe any significant statistical differences in consumption of berries, citrus, or stone fruits and other kinds of fruits across cases and controls. The adjusted estimates of colorectal cancer risk related to the daily consumption of apples (in quintiles) were based on the unconditional multivariate logistic model, which considered the set of potential confounding variables such as demographic characteristics of participants (age, gender, place of residency, marital status, tobacco smoking), total energy intake, intake of vegetables and fruits without apples. The results of the logistic analysis showed that the adjusted risk of colorectal cancer inversely correlated with daily number of apple servings. effective and cost-effective method for promoting dietary behavior change among older healthy adults. More research is needed to identify the optimal dose and timing for intervention strategies to promote dietary and physical activity change among both CRC survivors and the general population.

Methods: A prospective study, conducted in Krakow, in 382 non-smoking, no obese pregnant women between the ages of 18 - 35. The course of pregnancy was uncomplicated, finished with natural labor, in biological time limits. The impact of mother's nutritional status before pregnancy and weight gain on newborns weight, length and head circumference was estimated by multivariate linear regression. Results: The infant birth weight depended on mothers nutritional status before pregnancy and was lower in the group of underweight subjects (3381.6 g vs. 3479.9 g, p = 0.022). Women with low increase in body mass during pregnancy delivered newborns with lower anthropometrics parameters. The increase in body weight of one category resulted in statistically significant increase of birth weight by 140.9 g, increase of length by 0.51 cm and in head circumference by 0.27 cm. Conclusions: Increase in body mass during pregnancy is particularly important in the group of women underweight before pregnancy. Change of nutritional habits before and in the course of pregnancy may have beneficial effects for intrauterine fetal development.

We have measured personal PM 2.5 level in the group of 407 non-smoking pregnant women during the 2nd trimester of pregnancy. On average, the participants from the city center were exposed to higher exposure than those from the outer city area (GM = 42.0 Ag/m 3 , 95% CI: 36.8-48.0 vs. 35.8 Ag/m 3 , 95% CI: 33.5-38.2 Ag/m 3). More than 20% of study subjects were affected by high level of PM 2.5 pollution (above 65 Ag/m 3). PM 2.5 concentrations were higher during the heating season (GM = 43.4 Ag/m 3 , 95% CI: 40.1-46.9 Ag/m 3) compared to non-heating season (GM = 29.8 Ag/m 3 , 95% CI: 27.5-32.2 Ag/m 3). Out of all potential outdoor air pollution sources (high traffic density, bus depot, waste incinerator, industry etc.) considered in the bivariate analysis, only the proximity of industrial plant showed significant impact on the personal exposure (GM = 54.3 Ag/m 3 , 95% CI: 39.4-74.8 Ag/ m 3) compared with corresponding figure for those who did not declare living near the industrial premises (GM = 36.2 Ag/m 3 , 95% CI: 34.1-38.4 Ag/m 3). The subjects declaring high exposure to ETS (N 10 cigarettes daily) have shown very high level of personal exposure (GM = 88.8 Ag/m 3 , 95% CI: 73.9-106.7 Ag/m 3) compared with lower ETS exposure (V 10 cigarettes) (GM = 46.3 Ag/m 3 , 95% CI: 40.0-53.5 Ag/m 3) and no-ETS exposure group (GM = 33.9 Ag/m 3 , 95% CI: 31.8-36.1 Ag/m 3). The contribution of the background ambient PM 10 level was very strong determinant of the total personal exposure to PM 2.5 and it explained about 31% of variance between the subjects followed by environmental tobacco smoke (10%), home

At the request of the State Agency for the Prevention of Alcohol-Related Problems (PARPA), a version of the Reduced Drinking Programme (POP) was developed. The aim of the article is to profile E-POP application users in the context of the severity of alcohol-related problems in terms of gender and differences between registered users and those who had dropped out of the programme. Material and methods: E-POP was being used by 745 persons - 45.9% women and 54.1% men. They completed the Problem Drinking Scale (SPP), the Alcohol Use Disorder Identification Test (AUDIT) and the Polish version of Alcohol Dependence Scale (ADS-PL). Results: Mild and moderate alcohol use disorder (AUD) affected 28.5% persons while a severe disorder was observed in 23.3%. AUD was significantly less common in wo...

Results: The study showed that the adjusted birth weight was significantly lower in newborns whose mothers were exposed to particulate matter greater than 46.3 g/m 3 ( coefficient =-97.02, p = 0.032). Regression analysis stratified by the level of maternal fish consumption (in tertiles) showed that the deficit in birth weight amounted to 133.26 g (p = 0.052) in newborns whose mothers reported low fish intake (! 91 g/week). The birth weight deficit in newborns whose mothers reported medium (91-205 g/week) or higher fish intake (1 205 g/week) was insignificant. The interaction term between PM 2.5 and fish intake levels was also insignificant ( =-107,35, p = 0.215). Neither gestational age nor birth weight correlated with maternal fish consumption. Conclusions: The results suggest that a higher consumption of fish by women during pregnancy may reduce the risk of adverse effects of prenatal exposure to toxicants and highlight the fact that a full assessment of adverse birth outcomes resulting from prenatal exposure to ambient hazards should consider maternal nutrition during pregnancy.

All multivariate statistical models employed in the analysis considered potential confounders, such as demographic characteristics of subjects, body mass index, smoking status, leisure time physical activity, energy consumption and intake of meat products. Conclusions: The study results indicate that increased fish intake may have a preventive effect on CRC and modulate the effect of meat consumption. To our knowledge, this is the first large epidemiologic study on dietary habits and CRC incidence in Eastern Europe.

Design: The children's daily dietary intake was measured using the SFFQ. The average intake of three 24 h dietary recalls (24hDR) was calculated as a reference method. Wilcoxon's rank test and Spearman's rank-correlation coefficient were used to compare nutrient intakes assessed by both methods. The level of agreement between the SFFQ and the repeated 24hDR was determined by the Bland-Altman method. To assess the agreement in quartile distribution, the weighted kappa coefficient (k w) was used. Setting: Krakow, Poland. Subjects: One hundred and forty-three 3-year-old children and their mothers, participants of a prospective cohort study. Results: Overall, the SFFQ overestimated energy and nutrient intakes compared with the repeated 24hDR. The median correlation coefficient for energy and nutrient intakes was 0?456, with higher results for Ca, P and riboflavin. Although the k w value showed only slight to fair agreement between the two methods, about 75 % of the children were classified into the same or adjacent quartile and the level of agreement assessed by the Bland-Altman method for most of the nutrients investigated was good. Conclusions: The study indicated that the SFFQ might be a useful tool to assess dietary intakes of nutrients by small children, especially for ranking them according their nutrient intake.

Prowadzenie badań epidemiologicznych nad zależnością pomiędzy stanem zdrowia a sposobem żywienia wymaga, w pierwszej kolejności, trafnej oceny spożycia pokarmów oraz podaży składników pokarmowych. Cel. Celem badań była ocena wpływu wybranych czynników na trafność kwestionariusza częstości spożycia SFFQ w grupie dzieci przedszkolnych w wieku 3 lat ze środowiska krakowskiego. Materiał i metody. Do badań włączonych zostało 172 dzieci trzyletnich. W badaniach porównano podaż energii i wybranych składników pokarmowych, oszacowanych na podstawie półilościowego kwestionariusza częstości spożycia (SFFQ), z podażą tych składników, oszacowaną na podstawie trzech wywiadów 24-godz. Stopień zgodności pomiędzy badanymi metodami pomiaru określono na podstawie analizy skorygowanych współczynników korelacji Spearmana. Wyniki. Najwyższe współczynniki korelacji pomiędzy podażą oszacowaną na podstawie kwestionariusza SFFQ oraz trzech wywiadów 24-godz. zaobserwowano dla podaży witaminy B 2 (R S =0,635) oraz wapnia (R S =0,605), natomiast najniższe dla podaży witamin PP oraz A (odpowiednio R S =0,344 i R S =0,355). Czynnikiem w największym stopniu wpływającym na trafność danych żywieniowych było uczęszczanie przez dziecko do przedszkola.

Objectives: The purpose of the study was to determine the level of antibodies against SARS-CoV-2 in HCWs before and after vaccination with mRNA preparations according to previous COVID-19. Patients and methods: The HCWs from the University Hospital in Krakow completed two surveys: the baseline survey before receiving the first dose of vaccine (in January 2021) and the follow-up survey in June 2021. In parallel, two blood samples were collected from each participant at baseline and at follow-up. Total anti-SARS-CoV-2 antibody levels were measured using the ECLIA technique. Results: At baseline, 41.1% of HCWs had positive antibody test results, and at follow-up, the vaccinated HCWs had almost 100 times higher antibody levels than the unvaccinated HCWs. Participants under 30 years of age had significantly higher antibody levels in June than older HCWs.

MATERIAL AND METHODS The study comprised 1291 pupils - 632 girls and 659 boys from 17 Krakow middle schools. Their quality of life (QoL) was assessed by means of the Polish version of the KIDSCREEN-27 questionnaire. Five dimensions of QoL were analyzed as low, average and high QoL according to Polish cut-off points. The body mass index (BMI) of the adolescents was classified as underweight, normal weight, or excessive weight according to Polish growth charts. RESULTS Low QoL was observed significantly more often in girls than in boys. Excessive weight among both girls and boys was found to be a risk factor for low QoL in the "Physical Well-being" dimension as compared to normal weight adolescents. Additionally, boys with excessive weight had a two-fold higher risk of low QoL in the "Social Support & Peers" dimension (OR=2.00; 95 %CI:1.14-3.50). Underweight was associated with higher risk of low QoL in the "Physical Well-being", "Autonomy & Parents", and "Social Support & Peers" dimensions, but only among boys. CONCLUSIONS Both, underweight and excessive weight were associated with low QoL. Excessive weight in youth was linked mainly with lower physical well-being. Underweight was a predictor of low QoL only among boys in the dimensions related to physical health, as well as relations with family and peers.

These include, among other things, air pollutants in the environment associated with the highest prevalence of asthma, as well as respiratory and cardiovascular diseases in urban populations. There is strong evidence of health risks posed by human exposure to organic air pollutants such as PAH (polycyclic aromatic hydrocarbons) from combustion processes (solid fuels, coal and biomass) and communication. Generally, PAHs are formed during incomplete combustion and pyrolysis of organic material in a wide range of temperatures, up to over 1200 ° C. After entering the body, PAHs are transported to the alveoli and then spread throughout the body with the blood. The biological effects that PAHs cause in the human body are short-term, chronic, or long-term health effects, i.e. c...

In studies determining the relation between dietary habits and human health it is necessary to accurately assess the diet. The food frequency questionnaire allows for the assessment of the usual diet. However, it is important to evaluate the ability of this instrument to provide reliable information. Aim. To assess the validity of the semiquantitative food frequency questionnaire for measuring the dietary intake of 3-year-old children. Material & methods. The study included 60 children and their mothers, randomly selected from the previously established cohort study, conducted in Krakow. Repeated 24-hour dietary recalls were used as the reference method. The Wilcoxon's rang test and Spearman's correlation coefficients were used to compare the number of portions of each food group from SFFQ (semiquantitative food frequency questionnaire) and an average of three 24-hour recalls. To assess the agreement between the two methods in classifying individuals according to levels of intake the weighted kappa coefficient was used. Results. The number of servings for each food group from SFFQ was slightly higher as compared to the 24-hour recalls, and the largest differences were found for foods eaten very often or very rarely. Overall, the Spearman's correlation coefficients indicated a good or moderate agreement between both methods, except for the consumption of meat and meat products. The analysis of kappa coefficients confirmed the agreement in classification according to quartiles of intake. Although nearly 75% of the study population were classified within the same or adjacent quartile, the kappa coefficients did not reach statistical significance for meat and meat products. Conclusions. In most cases the presented questionnaire properly assessed dietary intake of food products and can be used to assess the usual diet for 3-year-old children.

Methods: A prospective study, conducted in Krakow, in 382 non-smoking, no obese pregnant women between the ages of 18 - 35. The course of pregnancy was uncomplicated, finished with natural labor, in biological time limits. The impact of mother's nutritional status before pregnancy and weight gain on newborns weight, length and head circumference was estimated by multivariate linear regression. Results: The infant birth weight depended on mothers nutritional status before pregnancy and was lower in the group of underweight subjects (3381.6 g vs. 3479.9 g, p = 0.022). Women with low increase in body mass during pregnancy delivered newborns with lower anthropometrics parameters. The increase in body weight of one category resulted in statistically significant increase of birth weight by 140.9 g, increase of length by 0.51 cm and in head circumference by 0.27 cm. Conclusions: Increase in body mass during pregnancy is particularly important in the group of women underweight before pregnancy. Change of nutritional habits before and in the course of pregnancy may have beneficial effects for intrauterine fetal development.

We have measured personal PM 2.5 level in the group of 407 non-smoking pregnant women during the 2nd trimester of pregnancy. On average, the participants from the city center were exposed to higher exposure than those from the outer city area (GM = 42.0 Ag/m 3 , 95% CI: 36.8-48.0 vs. 35.8 Ag/m 3 , 95% CI: 33.5-38.2 Ag/m 3). More than 20% of study subjects were affected by high level of PM 2.5 pollution (above 65 Ag/m 3). PM 2.5 concentrations were higher during the heating season (GM = 43.4 Ag/m 3 , 95% CI: 40.1-46.9 Ag/m 3) compared to non-heating season (GM = 29.8 Ag/m 3 , 95% CI: 27.5-32.2 Ag/m 3). Out of all potential outdoor air pollution sources (high traffic density, bus depot, waste incinerator, industry etc.) considered in the bivariate analysis, only the proximity of industrial plant showed significant impact on the personal exposure (GM = 54.3 Ag/m 3 , 95% CI: 39.4-74.8 Ag/ m 3) compared with corresponding figure for those who did not declare living near the industrial premises (GM = 36.2 Ag/m 3 , 95% CI: 34.1-38.4 Ag/m 3). The subjects declaring high exposure to ETS (N 10 cigarettes daily) have shown very high level of personal exposure (GM = 88.8 Ag/m 3 , 95% CI: 73.9-106.7 Ag/m 3) compared with lower ETS exposure (V 10 cigarettes) (GM = 46.3 Ag/m 3 , 95% CI: 40.0-53.5 Ag/m 3) and no-ETS exposure group (GM = 33.9 Ag/m 3 , 95% CI: 31.8-36.1 Ag/m 3). The contribution of the background ambient PM 10 level was very strong determinant of the total personal exposure to PM 2.5 and it explained about 31% of variance between the subjects followed by environmental tobacco smoke (10%), home

Results: The study showed that the adjusted birth weight was significantly lower in newborns whose mothers were exposed to particulate matter greater than 46.3 g/m 3 ( coefficient =-97.02, p = 0.032). Regression analysis stratified by the level of maternal fish consumption (in tertiles) showed that the deficit in birth weight amounted to 133.26 g (p = 0.052) in newborns whose mothers reported low fish intake (! 91 g/week). The birth weight deficit in newborns whose mothers reported medium (91-205 g/week) or higher fish intake (1 205 g/week) was insignificant. The interaction term between PM 2.5 and fish intake levels was also insignificant ( =-107,35, p = 0.215). Neither gestational age nor birth weight correlated with maternal fish consumption. Conclusions: The results suggest that a higher consumption of fish by women during pregnancy may reduce the risk of adverse effects of prenatal exposure to toxicants and highlight the fact that a full assessment of adverse birth outcomes resulting from prenatal exposure to ambient hazards should consider maternal nutrition during pregnancy.

Wilcoxon's rank test and Spearman's rank-correlation coefficient were used to compare nutrient intakes assessed by both methods. The level of agreement between the SFFQ and the repeated 24hDR was determined by the Bland-Altman method. To assess the agreement in quartile distribution, the weighted kappa coefficient (k w) was used. Setting: Krakow, Poland. Subjects: One hundred and forty-three 3-year-old children and their mothers, participants of a prospective cohort study. Results: Overall, the SFFQ overestimated energy and nutrient intakes compared with the repeated 24hDR. The median correlation coefficient for energy and nutrient intakes was 0?456, with higher results for Ca, P and riboflavin. Although the k w value showed only slight to fair agreement between the two methods, about 75 % of the children were classified into the same or adjacent quartile and the level of agreement assessed by the Bland-Altman method for most of the nutrients investigated was good. Conclusions: The study indicated that the SFFQ might be a useful tool to assess dietary intakes of nutrients by small children, especially for ranking them according their nutrient intake.

Prowadzenie badań epidemiologicznych nad zależnością pomiędzy stanem zdrowia a sposobem żywienia wymaga, w pierwszej kolejności, trafnej oceny spożycia pokarmów oraz podaży składników pokarmowych. Cel. Celem badań była ocena wpływu wybranych czynników na trafność kwestionariusza częstości spożycia SFFQ w grupie dzieci przedszkolnych w wieku 3 lat ze środowiska krakowskiego. Materiał i metody. Do badań włączonych zostało 172 dzieci trzyletnich. W badaniach porównano podaż energii i wybranych składników pokarmowych, oszacowanych na podstawie półilościowego kwestionariusza częstości spożycia (SFFQ), z podażą tych składników, oszacowaną na podstawie trzech wywiadów 24-godz. Stopień zgodności pomiędzy badanymi metodami pomiaru określono na podstawie analizy skorygowanych współczynników korelacji Spearmana. Wyniki. Najwyższe współczynniki korelacji pomiędzy podażą oszacowaną na podstawie kwestionariusza SFFQ oraz trzech wywiadów 24-godz. zaobserwowano dla podaży witaminy B 2 (R S =0,635) oraz wapnia (R S =0,605), natomiast najniższe dla podaży witamin PP oraz A (odpowiednio R S =0,344 i R S =0,355). Czynnikiem w największym stopniu wpływającym na trafność danych żywieniowych było uczęszczanie przez dziecko do przedszkola. Zaobserwowano również różnice w wielkości współczynników korelacji w zależności od poziomu wykształcenia i wieku matki oraz od masy ciała dziecka. Wnioski. Podaży energii oraz wszystkich badanych składników pokarmowych, oszacowana na podstawie kwestionariusza SFFQ, była znacząco wyższa w porównaniu do podaży wyliczonej na podstawie powtarzanych wywiadów 24-godz. Jednak trafność pomiaru podaży energii oraz podstawowych składników pokarmowych, mierzona współczynnikiem korelacji, była akceptowalna w odniesieniu do innych narzędzi wykorzystywanych do oceny żywienia dzieci.

Objectives: The purpose of the study was to determine the level of antibodies against SARS-CoV-2 in HCWs before and after vaccination with mRNA preparations according to previous COVID-19. Patients and methods: The HCWs from the University Hospital in Krakow completed two surveys: the baseline survey before receiving the first dose of vaccine (in January 2021) and the follow-up survey in June 2021. In parallel, two blood samples were collected from each participant at baseline and at follow-up. Total anti-SARS-CoV-2 antibody levels were measured using the ECLIA technique. Results: At baseline, 41.1% of HCWs had positive antibody test results, and at follow-up, the vaccinated HCWs had almost 100 times higher antibody levels than the unvaccinated HCWs. Participants under 30 years of age had significantly higher antibody levels in June than older HCWs.

MATERIAL AND METHODS The study comprised 1291 pupils - 632 girls and 659 boys from 17 Krakow middle schools. Their quality of life (QoL) was assessed by means of the Polish version of the KIDSCREEN-27 questionnaire. Five dimensions of QoL were analyzed as low, average and high QoL according to Polish cut-off points. The body mass index (BMI) of the adolescents was classified as underweight, normal weight, or excessive weight according to Polish growth charts. RESULTS Low QoL was observed significantly more often in girls than in boys. Excessive weight among both girls and boys was found to be a risk factor for low QoL in the "Physical Well-being" dimension as compared to normal weight adolescents. Additionally, boys with excessive weight had a two-fold higher risk of low QoL in the "Social Support & Peers" dimension (OR=2.00; 95 %CI:1.14-3.50). Underweight was associated with higher risk of low QoL in the "Physical Well-being", "Autonomy & Parents", and "Social Support & Peers" dimensions, but only among boys. CONCLUSIONS Both, underweight and excessive weight were associated with low QoL. Excessive weight in youth was linked mainly with lower physical well-being. Underweight was a predictor of low QoL only among boys in the dimensions related to physical health, as well as relations with family and peers.

These include, among other things, air pollutants in the environment associated with the highest prevalence of asthma, as well as respiratory and cardiovascular diseases in urban populations. There is strong evidence of health risks posed by human exposure to organic air pollutants such as PAH (polycyclic aromatic hydrocarbons) from combustion processes (solid fuels, coal and biomass) and communication. Generally, PAHs are formed during incomplete combustion and pyrolysis of organic material in a wide range of temperatures, up to over 1200 ° C. After entering the body, PAHs are transported to the alveoli and then spread throughout the body with the blood. The biological effects that PAHs cause in the human body are short-term, chronic, or long-term health effects, i.e. c...

In studies determining the relation between dietary habits and human health it is necessary to accurately assess the diet. The food frequency questionnaire allows for the assessment of the usual diet. However, it is important to evaluate the ability of this instrument to provide reliable information. Aim. To assess the validity of the semiquantitative food frequency questionnaire for measuring the dietary intake of 3-year-old children. Material & methods. The study included 60 children and their mothers, randomly selected from the previously established cohort study, conducted in Krakow. Repeated 24-hour dietary recalls were used as the reference method. The Wilcoxon's rang test and Spearman's correlation coefficients were used to compare the number of portions of each food group from SFFQ (semiquantitative food frequency questionnaire) and an average of three 24-hour recalls. To assess the agreement between the two methods in classifying individuals according to levels of intake the weighted kappa coefficient was used. Results. The number of servings for each food group from SFFQ was slightly higher as compared to the 24-hour recalls, and the largest differences were found for foods eaten very often or very rarely. Overall, the Spearman's correlation coefficients indicated a good or moderate agreement between both methods, except for the consumption of meat and meat products. The analysis of kappa coefficients confirmed the agreement in classification according to quartiles of intake. Although nearly 75% of the study population were classified within the same or adjacent quartile, the kappa coefficients did not reach statistical significance for meat and meat products. Conclusions. In most cases the presented questionnaire properly assessed dietary intake of food products and can be used to assess the usual diet for 3-year-old children.
