Cíl: Cílem studie bylo zjistit potencionální riziko hypertenze u dětí ve věku 14 – 15 let dvojím standardním měřením krevního tlaku a zmapovat moţný vztah mezi hodnotami krevního tlaku dětí a jejich vybranými sociodemografickými faktory a tělesnými parametry. Metodika: Výzkumný soubor tvořilo 143 ţáků 8. a 9. tříd základních škol v Ostravě zapojených do projektu Zdravá škola. Data byla získána měřením fyziologických funkcí a antropometrických dat a doplňujícími otázkami na vybrané rizikové faktory kardiovaskulárních chorob. Výsledky: Měření krevního tlaku (TK) proběhla opakovaně, při druhém měření byla prokázána odlišnost naměřených hodnot TK mezi pohlavími, kdy u chlapců byly hodnoty TK vyšší neţ u děvčat. Bylo potvrzeno, ţe na hodnoty TK má vliv pohybová aktivita, a to zejména u dětí s vysokými hodnotami BMI. U normálních hodnot BMI korelace mezi hodnotou krevního tlaku a pohybovou aktivitou nebyla statisticky významná. Z rizikové skupiny 14 dětí s rodinnou predispozicí hypertenze bylo evidováno 29 % dětí s průměrnou hodnotou TK v pásmu pro 95. percentil (hypertenzní hodnoty) vzhledem k danému věku, pohlaví a výšce. Závěr: Výskyt vysokého TK byl četnější u dětí s nadváhou a obezitou. Pohybová aktivita ovlivňovala hodnotu krevního tlaku, zvláště pak právě u dětí s nadváhou a obezitou, kdy hodnoty TK u těchto dětí, které necvičily, byly vyšší neţ u dětí cvičících. Pravidelným měřením a správným zhodnocením TK můţe sestra včas zachytit děti a adolescenty s rizikovými parametry., Aim: The aim of the thesis is to examine potential risk of hypertension in children aged 14 - 15 years by two standard measurements of blood pressure and to find out possible relation between values of blood pressure in children and their selected socio-demographic factors and physical parameters. Methods: The research was carried out on 143 pupils from elementary schools in Ostrava, which participate in the project „Zdravá škola“(Healthy School). The data were obtained from measuring of physiological functions, survey of anthropometric data and further questions focused on particular risk factors for cardiovascular diseases. Results: The second measurement revealed a difference in values of blood pressure between sexes, when boys had higher blood pressure than girls. The research confirmed that blood pressure is influenced by physical activity, especially in children with high value of BMI. In children with lower values of BMI, the correlation between the value of blood pressure and physical activity was not statistically relevant. From a high-risk group of 14 children with genetic predisposition, 29% of children had average value of blood pressure in range of 95. percentile (hypertension) given age, sex and height. Conclusion: The occurrence of high blood pressure is common in children who suffer from overweight and obesity. The value of blood pressure is influenced by physical activity, especially in overweight and obese children, when value of blood pressure in the children who did not practice, were higher in children than exercisers. Regular check-ups and proper evaluation of measured blood pressure in children and adolescents can contribute to early revelation of children and adolescents with high-risk parameters of blood pressure., Alena Petzuchová, Darja Jarošová, and Literatura 16
We studied the demography, movement, behaviour and choice of nectar plants by adults of Aporia crataegi. This study was done in a dense network of different types of habitats (total size of study area 16.26 ha) from open landscape to shrubland, the latter being a result of abandonment of traditional agricultural practices such as extensive mowing and grazing. Total population size was estimated to be approximately 1700 and 2700 for females and males, respectively. Median and maximum distances moved by males were 134 and 3493 m, and by females 138 and 3165 m, respectively. The average lifespan was ca. 7.1 and 7.5 days, with maximum recorded lifespans of 21 and 17 days for males and females, respectively. The greater capture probability recorded for males indicates their high activity, as they spend most of their time in flight patrolling and searching for mates. A parabolic recruitment curve and protandry were also recorded. Both sexes are highly mobile. The spatial distribution of both sexes was roughly similar. The adult behaviour differed in different habitats, with more time spent feeding and resting when nectar plants were plentiful and more time spent flying when they were rare. Although adults utilized nine nectar sources, only two were recorded in over 80% of all the feeding occasions. In order to re-establish open grassland with some shrubland, traditional and mosaic management of the landscape should be revived at least to some extent., Jure Jugovic, Mitja Črne, Martina Lužnik., and Obsahuje bibliografii
