Background. Physical activity is considered to be one of the most important determinants of human health. Many authors emphasize the benefits of physical activity for elderly people – its positive influence on the functioning of many organs and systems, development of greater mobility, slowdown of the involution processes, and counteracting the effects of civilization diseases. Objective. The aim of this study was to analyze the structure of physical activity in older adults from the Lower Silesian region. Material and method. The data was collected as part of the PolSenior national program. The subjects were selected randomly in three stages. The analysis was performed on the data from questionnaires filled out by 192 men and 164 women over the age of 65 years living in the Lower Silesian region. The answers were analyzed in categories such as: age (3 groups: 65-74 years, 75-84 years and over 85 years), gender, place of residence (communities up to 20 000 and over 20 000 inhabitants) and social-occupational status (blue-collar and white-collar workers). The survey results were shown in percentage form and concerned the different types of physical activity performed, the most frequent reasons for undertaking physical activity, sports and recreational physical activity during the respondents youth, between 30 and 60 years of age and at present, as well as the constraints and reasons that prevent an active lifestyle. Results. With age the percentage of people who spend their free time actively decreases. In each age group of elderly people men declared a greater need for physical activity than women. The subjects also differed with the urban factor and socialoccupational status. Moreover, the results showed that the larger community, the better the condition created for recreation of older adults and the people whose previous profession was not connected with physical work tried to be physically active in various forms more often than ex-manual laborers. It is probable that education significantly influences an active attitude towards one’s health and proper lifestyle. Conclusions. Physical activity of seniors as a one of the basic elements of lifestyle is clearly connected with the environment in which older people live.
When asked to describe air pollution, the average person will invariably mention the word “smog”. Although the term is often poorly understood, social awareness of it is much higher than just a few years ago. In the era of globalization, it has become clear that smog goes beyond dust and gas pollution and encompasses the microbiological purity of the air. This is due, among other things, to the fact that the human body may not only be a reservoir but also an emitter of microbiological particles dangerous to health and life. According to Górny, SCMB (Harmful Microbiological Factors) are easier to aerosolize compared to other air pollutants [1]. It highlights the risk of infectious diseases from abroad, including allergic disease entities. It also emphasizes the close relationship between various types of air pollution.
The topicality. The indicators of life quality are undetermined and unstandardized; the problem of determination of a single quantitative meaning of the quality of life remains unsolved. The aim of the research – to describe modern approaches to determining the quality of life and on their basis to propose a comprehensive theoretical model for the explanation of life quality phenomenon and the role of health in its formation. Methods: analysis and synthesis of scientific literature, documentary data; methods of theoretical research (analysis, synthesis, specification, classification, historical method, comparative analysis, system and structural analysis). The results: It has been proved that the quality of life is closely related to the health of human beings and it includes physical, mental and social being, considering the beliefs, expectations and world outlook. Based on the theoretical analysis and synthesis, it proposes the multicomponent structure of the quality of life, taking into account both positive and negative aspects of life, common to people of different sex, age, and state of health. Domains, sub-domains, indicators, and variables were defined as the main components of the model. Physical Component, Mental Component, Social Activity, Material Component, Development and Identity, Environment were assigned to the components of the highest level. The health-related quality of life was separated as the single part of the model. Conclusions and recommendations for further research. The theoretical model based on the principles of consistency, hierarchy, equality, determinism, unity of internal factors and external conditions was developed.
The medial circumflex femoral artery (MCFA) usually branches from the deep femoral artery (DFA). It may also branch from the femoral artery (FA). In this study 100 inguinal regions of 50 cadavers were investigated. In 79 extremities (79%) MCFA branched from DFA, while in 15 (15%) it branched from FA. In four extremities (4%) MCFA was found to be double; in each case one of MCFAs branched from FA and the other from DFA. In one of these four cases the lateral circumflex femoral artery (LCFA) was also double. In one case we found a common trunk of DFA and MCFA and in another case a common trunk of MCFA, DFA and LCFA. Clinicians must be familiar with the variations of this clinically important artery to improve their success in the diagnosis and treatment of pathologies in the region.
Introduction. The results of breast cancer treatment depend mainly on better detection in mammography screening and, consequently, a higher proportion of women with early stage of the disease. They depend also on a better access to health care services and the effectiveness of oncological treatment. One of the methods of breast cancer control is a breastconserving surgery. With a proper patients’ classification for the treatment, the results of the breast-conserving surgery do not differ in relation to mastectomy. That’s why, the availability of breast-conserving surgical methods is particularly important, especially in a population in which a population screening is conducted. Objective. The analysis of the selected aspects of the breast cancer treatment’s standard in Podlaskie Voivodeship. Patients and methods. In years 2001–2002, 709 cases of women with breast cancer were reported to the Voivodeship Cancer Registry in Bialystok. 659 women were diagnosed with a primary invasive breast cancer. Based on a cohort of 499 women treated with radical methods the following indicators, recommended by WHO for the evaluation of the breastconserving surgery’s availability, were calculated: a percentage of patients with whom breast-conserving surgery was used, a proportion of breast cancer cases receiving post-operative breast radiotherapy after breast-conserving surgery and a proportion of breast-conserving surgery in pT1 cases. Results. The breast-conserving surgery has been used much less frequently in Podlaskie Voivodeship than in Western Europe, but more frequently than in Poland in general. Conclusion. It should be aimed to provide a surgical treatment with the use of breast-conserving surgical methods to the highest possible percentage of patients. The increase of the percentage of patients treated with breast-conserving surgery methods can be a result of an effective screening realisation.
Variations of the branches of the aortic arch are likely to occur as a result of the altered development of certain branchial arch arteries during the embryonic period of gestation. In the present investigation the pattern of branches of the aortic arch was studied in 81 cadavers from a recent South Australian population of European descent, who have migrated to (n = 38) or were born and lived in (n = 43) South Australia during the twentieth century. Two principal variations were noted in the present study. Firstly, in 6 cadavers, the left vertebral artery originated directly from the arch of the aorta, between the left common carotid and the left subclavian arteries. The 6 subjects were among the subgroup born in South Australia, giving an incidence of 13.95%, which is much higher than in previous reports. The overall incidence of 7.41%, when related to the whole group, is also higher than incidences reported in other populations. The presence of this variation suggests that in some individuals part of the aortic arch is formed from the left 7th inter-segmental artery. Secondly, none of the cadavers examined had the thyroidea ima artery, contrasting with previously reported incidences that varied between 4% and 10%. Since all 6 cadavers with the left vertebral artery variant were born in South Australia, it is suggested that environmental factors may have contributed to this variation. Significant environmental changes in South Australia around the turn of the twentieth century are discussed. This study represents the first systematic investigation of the branches of the aortic arch in a South Australian population and provides data relevant to the practice of medicine.
In the Pol-Monica nutritional study salt intake in urban (Warsaw) and rural (Province of Tarnobrzeg) populations was assessed. Studied sample comprised 2490 men and 2738 women aged 35 to 64 years. Salt intake was significantly greater in the urban population (10-15 g) than in the rural population (8-12 g), and it was greater also in the male population (12-15 g) than in the female population (8-10 g). In the rural area the main salt source were soups (28-30%) while in the urban area the main source were bread, and rolls (23-24%). No significant age-related differences were observed in salt intake.
Dobrze znane są zwyczaje żywieniowe ludzi starszych zamieszkałych w różnych rejonach Szwecji. Wykazują one duże podobieństwo. W większości przypadków przeciętne spożycie energii i składników odżywczych znacznie przekracza zalecane normy spożycia; zróżnicowanie jest jednak duże, co odzwierciedlają wartości odchylenia standardowego osiągające często 25% wartości średnich. Niektóre składniki odżywcze, jak białko, wapń i witamina D, jak również pewne wskaźniki i czynniki ryzyka zasługują na szczególną uwagę.
The study aims at statistical and spatial analysis of population ageing in Poland’s 2479 communes (LAU2 - Local Administrative Unit 2) as of December 31, 2014 based on quantitative data from the Local Data Bank, the Central Statistical Office of Poland. The paper presents the results of applying the following indices: the share of the old in the population, double ageing index and the ageing index by A. Sauvy. Findings prove that 9% of Polish communes are old and 91% are very old according to UNO classification. In Polish LAU2s the share of elderly people (65%+) in total population ranges from 7% to 39,3%, double ageing index from 2,9% to 20,8% and the number of the old per 100 young amounts from 25,3 to 306,1. Thus communes characterised by the lowest values of applied indices should be perceived as ‘the youngest’ among the old. The oldest communes accumulate in Eastern Poland, which makes it the oldest region in the country. That advanced ageing of the local population can be the main threat to the development of those communities unless balanced by the inflow of exogenous demographic potential.
The Renin-Angiotensin System (RAS) is an important regulator of the blood pressure(BP). The level of the vasoactive peptide Angiotensin-II, is mainly determined by the RAS enzyme, angiotensin converting enzyme-1 (ACE-1). Polymorphisms in ACE gene is reported to be associated with hypertension in various populations worldwide. We investigated the association of ACE I/D polymorphisms with hypertension among the tribal populations of South India. Samples were collected from hypertensive patients (n = 33) and healthy controls (n = 37). Genotyping was performed using Polymerase chain reaction (PCR) with allele specific primers. The DD genotype is significantly observed among the cases (OR = 1.0) . Specifically, the DD genotype is more evident among the females (OR = 0 .705) than males (OR = 1.22) and is analysed to be associated with hypertension among the tribal populations of South India.
Food intake, body mass index (BMI), serum lipids, blood glucose, systolic and diastolic blood pressure and pulse wave velocity were measured in the population of 2559 males aged 25-59 years employed in a foundry in Cracow in 1972-1974. Abnormal dietary habits were revealed. The share of protein in total energy intake was 11.7%, fats 37.1% and carbohydrates 51.2% (sugar 11.6%). The mean BMI was 25.3 ± 3.1 BMI above 25 was found in 44% of males under study. It has been shown that serum cholesterol, total lipids, esterified fatty acids, systolic and diastolic blood pressure, and pulse wave velocity were positively correlated with BMI. It is concluded that obesity prevention and treatment should be recognized as. an important method in prevention of coronary heart disease.
As part of the Pol-Monica Programme realized in 1984 the dietary habits of a population of over 5 thousand persons, aged 35-64, from a rural area (Province of Tarnobrzeg) and an urban area (Warsaw) were evaluated. A significant effect of the social environment and sex was noted on the energy and nutritional value of meals and on the consumption of products in them. In the urban environment these values were usually higher than in the rural environment; besides that a higher energy value of the daily food ration and higher amounts of basic nutrients in it were noted in the diet of males than in that of females. In relation to the RDA, the intake of fats by males, especially in the Warsaw population, exceeded greatly the suggested value, while the content of vitamin C in the diet of males and females in both populations was very low, only 30-40% of the recommended value.
