Case-control study of lifetime occupational and recreational physical activity and risks of colon and rectal cancer.

Important aspects of the inverse relation between physical activity and colon cancer risk are still under discussion. In 2000-2003, 239 incident cases of colorectal cancer confirmed by histopathology and 239 hospital-based controls, matched by age and gender, were enrolled. In standardized interviews, data on occupational and recreational physical activity for ages 20, 30, 40, 50 and 60 years were collected from 98 colon cancer cases, 141 rectal cancer cases, and from 193 controls.

[Intake of pharmacologic supplements of vitamins and minerals during pregnancy. Survey conducted in Krakow].

The aim of this study was to describe pharmacological supplements during pregnancy in the sample of 406 nonsmoking women, residents of Krakow. Multivitamins' supplements were taken by 79.1%, folic acid by 41.

Estimated risk for altered fetal growth resulting from exposure to fine particles during pregnancy: an epidemiologic prospective cohort study in Poland.

The purpose of this study was to estimate exposure of pregnant women in Poland to fine particulate matter [less than or equal to 2.5 microm in diameter (PM 2.5)] and to assess its effect on the birth outcomes.

Helicobacter pylori, non-steroidal anti-inflammatory drugs and smoking in risk pattern of gastroduodenal ulcers.

Background: Helicobacter pylori, NSAID and cigarette smoking are major risk factors for gastroduodenal ulcers. However, the results of studies on the interaction between these factors on ulcerogenesis are controversial. This study was designed to examine the association between gastroduodenal ulcers and H.

Effect of prenatal PAH exposure on birth outcomes and neurocognitive development in a cohort of newborns in Poland. Study design and preliminary ambient data.

Preliminary data suggest an association between infant mortality rates and several measures of ambient air pollution, including dustfall and polycyclic aromatic hydrocarbons (PAH). The effects of airborne PAH components on fetal growth and early childhood development are of primary interest since we have previously demonstrated that these pollutants were associated with significant decrements in birthweight, length and head circumference in Polish newborn babies. The undertaken research combines a state-of-the-art environmental monitoring and molecular approaches with comprehensive neurodevelopment assessments.

[Protective effects of physical activity in the occurrence of colon cancer].

The purpose of the study was to assess the role of occupational and leisure physical activity on the risk pattern of colon cancer considering the possible confounding effects of dietary habits. Case-control study has been carried out in 180 incident cases of colon cancer hospitalized in Chair of Surgery CMUJ in Kraków. The equal number of controls individually matched by gender and age were chosen amongst patients with no history of cancer from the university hospital.

Alcohol consumption and the risk of colorectal cancer at low levels of micronutrient intake.

Background: The purpose of our study was to assess the relationship between simultaneous exposure to alcohol and consumption of micronutrients that may have protective properties against colorectal cancer.

Material/methods: This hospital-based case-control study of colorectal cancer was carried out between January 1998 and November 1999 in Cracow, Poland. A total of 180 cases of colorectal cancer confirmed by histopathology were recruited from the University Hospital in Cracow.

Nutrient intake patterns in gastric and colorectal cancers.

The purpose of the study was to present the dietary risk pattern in gastric and colorectal cancers, using the same methodological approach in a parallel hospital-based case-control study. In all, 180 cases of colorectal cancer and 80 cases of stomach cancer, confirmed histopathologically, were enrolled from the University Hospital in Cracow. A high intake of carbohydrates was associated with an increased risk of colorectal cancer (OR = 2.

Risk of colorectal cancer from alcohol consumption at lower vitamin intakes. A hospital-based case-control study in Poland.

The purpose of the study was to assess the relation between the simultaneous exposure to alcohol and consumption of micronutrients that have protective properties against colorectal cancer. A hospital-based case-control study of colorectal cancer was carried out between January 1998 and November 1999 at the University Hospital in Krakow, Poland. In total, 180 incident cases of colorectal cancer, confirmed by histopathology, were recruited and an equal number of controls, individually matched by gender and age (+/-5 y), were chosen amongst patients with no history of cancer.

Combined risk assessment of physical activity and dietary habits on the development of colorectal cancer. A hospital-based case-control study in Poland.

The purpose of the study was to assess the importance of physical activity performed both in occupational settings and in leisure time on the risk of colorectal cancer, considering the possible confounding effects of dietary habits. The hospital-based case-control study was carried out in Poland. In total, 180 incident cases of colorectal cancer were recruited.
