Urbanization processes of areas located within large cities entail a number of consequences, such as a change in employment structure of inhabitants in these areas. New housing developments attract a stream of well-educated and affluent urban dwellers, who move to the suburbs and contribute to the transformation of dominating functions in the areas located near the cities. Based on selected empirically measurable characteristics, synthetic measures were calculated for the phenomena analyzed with the use of the Hellwig method. The following functions have been included: agricultural, recreational, service, industrial, and residential. Based on the conducted analysis, it can be claimed that most of the examined municipalities are characterized by multifunctional development, with no dominant function apparent. Also, the analysis revealed the existence of three social classes in the studied areas, distinguished by a very high, high, or average standard of living of their members. The study found that the highest standard of living is typical for the municipalities where industrial and service-related functions dominate.
Background. Obesity is well known cause of various diseases. However, there are only a few studies which enable to compare directly the magnitude of risk in different groups of chronic diseases. Objectives. The aim of presented paper was to identify a magnitude of the risk of chronic diseases attributable to overweight and obesity on the basis of data on weight and height self-reported by respondents. Material and methods. The survey was conducted among 402 Warsaw inhabitants selected by non-random method. Overweight and obesity was measured by Body Mass Index (BMI) on the basis of the data of weight and height reported by respondents. According to WHO criteria the normal weight is defined as BMI 18.5 - 24.9 kg/m2, overweight as BMI 25.0 - 29.9 kg/m2, and obesity as BMI 30 kg/m2 or more. The following groups of chronic diseases were included: cancer, diabetes and other endocrine diseases, mental disorders, cardiovascular diseases, respiratory diseases, digestive diseases, arthritis and allergy disorder. Results. Obesity measured by self-reported method was recognised as significant risk factor for diabetes (OR=9.6, Cl: 2.0152.8), respiratory diseases (OR=10.6, Cl: 3,0-333,7), cardiovascular diseases (OR=5.2, Cl: 1.9-108.3), arthritis (OR=6.3, Cl: 2.4-266.7), digestive diseases (OR=3,8, Cl: 1.3-83.6) and mental disorders (OR=5.8, Cl: 1.5-29.1), while overweight significantly increased the risk of diabetes (OR=4.4, Cl: 1.2-10.8), respiratory diseases (OR=3.2, Cl: 1.4-22.2), cardiovas- culardiseases (OR=2.9, Cl: 1.2-6.4) andarthritis (OR=3.0, Cl: 1.1-9.6) Conclusions. Our findings showed that data on weight and height collected by survey method provide some information about the magnitude of the risk regarding particular groups of diseases attributable to overweight and obesity, nevertheless, underestimation ofBMI calculated in this way should be taken into account.
The aim of this study was: (a) to estimate the concentration of selenium in plasma of 136 residents (59 men and 77 women) of the Gdansk region, northern Poland, aged 19-70; and (b) to compare the obtained results with data corresponding to healtly populations living in different European countries. Selenium in plasma was determined by atomic absorption spectrometry using the hydride generation method. The mean selenium concentration in plasma of the investigated persons was: 72.3 +/- 14.1 mug/l, in men 75.9 +/- 12.8 mug/l, in women 69.5 +/- 14.7 mug/l. No age-dependent differences in plasma selenium were found in the investigated population. In 22% of the investigated persons the selenium level in plasma was lower than 60 mug/l. The obtained results indicate that a significant part of this population is deficient in selenium and should be supplemented with this element.
The amounts of lead and cadmium, determined analytically in the food rations of the inhabitants of selected rural households located in the Czarnocin region (Świętokrzyskie Province) did not exceed the provisional tolerable weekly intake (PTWI) in any of the analysed households or seasons. The average lead and cadmium intake accounted for 22% and 53% respectively of the PTWI in autumn, and 28% and 63% respectively in spring.
The aim of the present work was to evaluate the mercury content in hair of inhabitants of Wrocław, in southwestern Poland. On the basis of a questionnaire and analysis of hair by atomic absorption spectroscopy, it was possible to indicate the sources of mercury exposure. The mean mercury level in hair of the whole population (n=321) was 0.203±0.181 mg·kg⁻¹. The content of mercury in hair of subjects who consumed fish exceeded the upper limit of reference value, which was 0.397 mg·kg⁻¹. Subjects who declared consumption of fish, honey, and mouldy cheese, contained statistically more mercury: 60.5%, 35.4%, and 37.8%, respectively, than those who did not eat these types of food. It was noticed that there was no effect from the place of residence, the presence of pollution emitters, gender, age, weight, height, presence of amalgam fillings, hair dyeing, and smoking cigarettes on mercury content in hair.
Introduction and objective. Epidemiological assessment of maxillofacial fractures carried out by a given specialized centre may constitute valuable material for comparison with other regions of Poland and the European Union. This material could help standardize the present methods of treating craniofacial skeleton dislocations, and plan appropriate financial resources both for specialized treatment of such fractures and fractures that require multidisciplinary care. Moreover, the frequency of complicated maxillofacial fractures leading to residual disability and circumstances in which fracture occurred may be useful for the Social Security authorities. Materials and methods. This study is a continuation of research on maxillofacial traumatology carried by the Maxillofacial Department of the Medical University in Wrocław, Lower Silesia. Since 1956, a statistical review of maxillofacial fractures has been kept in 5 or 10-year periods. Statistical analysis of this kind is useful in indentifying the frequency of the phenomenon, taking suitable treatment precautions, verifying treatment methods, and analyzing costs and losses incurred as a result of absence at work. Sociological aspect of such studies includes indicating sources of socially adverse phenomena, i.e. violence or alcohol abuse. The studies were based on clinical documentation of 937 patients, where dependencies between chosen parameters were identified. As a basic statistical analysis of variable interdependence the χ2 test of independence was applied. Conclusions. Lately, there have been more maxillofacial fractures resulting from civilization changes. Simultaneously, there are new treatment methods and significant progress has been made regarding materials that are used in these treatments.
Background. Tea is a very popular drink throughout many parts of the world, that includes Poland. The tea infusion (cup of tea) itself contains phenolic compounds with anti-oxidant properties that constitute 30% of the dry mass of tea leaves responsible for a health promoting effect on the human body. Objectives. To estimate the determinants and amounts of black and green tea consumed by a selected population group, along with their polyphenols intake from tea. Material and Methods. A survey was conducted of 281 subjects in 2012 from the Mazovian region of Poland, recruited from social-networking sites which had been sent a web application questionnaire (Mini-ankiety.pl). Results. Subjects were aged 18-56 years, of whom the majority (73%) were aged 21-30 years. City dwellers constituted 86%, whilst those remaining were from small towns (14%). Black tea was drunk by 80% of whom 39% did so daily, whilst green tea was drunk by 72% of whom 17% did so daily. Determinants affecting the amounts of tea drinking were principally gender, education, place of residence and number of household members. Women significantly drank more than one cup of green tea daily compared to men. Those with a higher education significantly drank more than one cup of black tea daily compared to those with lower education levels. Homeowning subjects with 2 household members significantly drank more than one cup of green tea daily than the others. The average daily intakes of polyphenols from black tea in those who drank so regularly was 503 mg and that for green tea was 361 mg. Conclusions. The main source of tea polyphenols was found to be black tea as this was drunk more often than green tea. There is a need for promoting more green tea to be drunk as a source of polyphenols.
Background. The use of dietary supplements is widespread and can contribute substantially to total nutrient intake. However, it also generates some potential risks in the case of unreasonable and excessive use of such products. Objective. To estimate the prevalence of supplementation and the vitamin supplement contribution to total intake among Warsaw population aged 20-74 years. Material and methods. Nutrient intake and supplement use were studied in a representative sample of Warsaw population in years 2011/12 (486 men and 421 women) and in 2001 (658 and 671 respectively). The vitamin levels were analyzed in reference to the Recommended Dietary Allowance (RDA) and the tolerable upper intake level (UL). Results. In the years 2011/12 the use of dietary supplements (vitamins and minerals) was reported by 31% men and 40% women. Vitamin intake from food showed the deficiency of vitamins D, B1 and folates and adequate intake of vitamins A, C, E, B2, B6, B12. Supplementing with vitamins D and B1 as well as folic acid contributed to better RDA fulfillment. Supplementing with vitamins A, C, E, B2, B6 and B12 was not justified because these vitamins were taken in sufficient amounts with food. In 1.3%-14.9% supplement users, the total intake of vitamins A, C, E and B6 exceeded the UL. The prevalence of supplementation of vitamins A, C and E did not change between 2001 and 2011/12, but the total intake of vitamin A in both sexes and vitamins C, E in women was significantly higher in 2001. Conclusions. The use of dietary supplements in Warsaw population was widespread and in case of some vitamins- unreasonable.
Background. The excessive use of health care services by obese people constitutes a serious financial burden to all highly developed countries. As yet however, this has not been recognised to be a problem in Poland. Objective. To provide a preliminary analysis of Warsaw inhabitants in their use of and quality of received health care by comparing obese subjects with those of normal weight. Materials and methods. Study subjects were fifty three obese (BMI>30) and one hundred eighty one normal weight (18.5
