Autoři ve svém příspěvku uvádějí první výsledky šetření, které bylo zaměřeno na zjištění hmotností školních tašek chlapců a dívek 1. a 2. tříd základních škol v olomouckém regionu. Celkem byla zjištěna hmotnost u 502 školních tašek, změřeno 502 dětí (263 dívek a 239 chlapců). Z výsledků měření je zřejmé, že hmotnost tašky se zvyšuje s postupem žáků do vyšší třídy. Největší rozdíl mezi minimální a maximální hodnotou hmotnosti tašky byl zjištěn u 8letých dívek, činil 8,9 kg. Výsledky ukázaly, že procentuální podíl hmotnosti tašky doporučeným 10 % tělesné hmotnosti dítěte odpovídal pouze u 17,5 % dětí. 82,5 % dětí pak nosí aktovky těžké (10–20 %), přičemž 18,3 % dětí nosí aktovky o hmotnosti nad 20 % své tělesné hmotnosti, což už lze považovat za extrémně těžké. Nepřiměřená hmotnost školní tašky pak může ovlivňovat držení těla a výskyt bolesti zad., Effects of the weights of school bags carried by pupils from the first two classes of primary schools in the Olomouc region (502 schoolbags belonging to 263 girls and 239 boys) on the pupils’ posture were examined. The weight of the schoolbags of pupils from the 2nd year class was found to be higher than of pupils in the first year. The greatest difference between minimum and maximum weights (8.9 kilograms) was detected in the schoolbags of 8 year old girls. Only 17.5% of children carried bags that were within the recommended 10% of the child’s body weight. Thus, 82.5% of the children carry heavier bags and 18.3% of these pupils carry extremely heavy bags (over 20% of their body weight).We conclude that the excessive weight of school bags contributes to poor posture and backache amongst these children., Hana Kabátová, Miroslav Kopecký, Dana Strnisková, Jitka Tomanová, and Literatura 5
Fatty acid (FA) profiles as potentially relevant components of Crohn’s disease (CD) have been insufficiently analysed. We sought to explore the plasma profiles of n-3 and n-6 polyunsaturated fatty acids (PUFAs) in newly diagnosed untreated active CD. We included 26 consecutive CD pediatric patients (<19 years) and 14 healthy controls (HCs). Disease characteristics, including inflammatory markers, dietary histories, and the Pediatric Crohn’s Disease Activity Index (PCDAI), were obtained. The profiles of plasma FAs in plasma lipid classes were analysed by gas chromatography with FID detection of methyl esters. The erythrocyte sedimentation rate, C-reactive protein level and fecal calprotectin level (all p<0.001) were significantly higher in CD patients than in HCs. Most changes were observed in plasma phospholipids (PLs), such as a higher content of n-3 and changes in n-6 long-chain PUFAs in the CD group. The CD group had a lower ratio of n-6/n-3 PUFAs in PLs (p<0.001) and triacylglycerols (TAGs) (p<0.01). Correlations of the FA content in plasma PLs with disease activity scores of CD were also observed, which were positive for the sum of monounsaturated fatty acids (MUFAs) as well as oleic acid (18:1n-9) (both p<0.05). The metabolism of PUFAs is significantly altered even in treatment-naïve newly diagnosed active pediatric CD, and the content of major FAs in PLs correlates with disease activity and inflammatory markers, thus probably contributing to the still unclear early disease pathogenesis., Jan Schwarz, Marek Vecka, František Stožický, Renáta Pomahačová, Barbora Staňková, Eva Tvrzická, Marcela Kreslová, Romana Zahálková, Josef Sýkora., and Obsahuje bibliografii

Objectives. The main goal of the study was to analyse in detail specific family indicators and their relation to selected indicator of life satisfaction in a representative sample of Czech children. Sample and setting. A total number of 4 351 children aged 11, 13 and 15 years out of 88 randomly selected schools in Czech Republic formed the study population. The data was acquired in the framework of the WHO study “The Health Behaviour in School-aged Children: A WHO Cross National Study” (HBSC) in June 2010 by means of standardized questionnaires. Research questions. Is formal structure of family or the quality of communication more important for children's life satisfaction? Statistical analysis. Statistical analysis included descriptive analyses, the x2 test of independence in contingency tables, Fisher’s exact test, two samples T-test, one and two way analysis of variance using the NCSS 2007 program. Logistic regression analysis was performed to evaluate the influence of family on life satisfaction of children and prevalence odds ratios with 95% confidence interval were calculated as measure of association. Results. Life satisfaction was high for majority of children, it reached two thirds of possible maximum at both of the followed scales (Cantril index, Huebner scale) for the whole sample. Life satisfaction was significantly associated (p<0,001) with age, gender, formal structure of family and quality of communication in family. Children from complete families with easy or very easy communication with both parents had the highest values at both of the followed life satisfaction scales. Study limitations. Limitations of the study result from the cross-sectional design and data based on self-reports. Both life satisfaction and family were analysed on the basis of selected question categories., L.
