The purpose of this study was to identify the possibility of unnoticed reduction in salt content of bread as a basic food in the diet of preschool children. The response of children to less salty ...bread and the role of teachers and teacher assistants in the introduction of novelties into children's nutrition ware studied.
Using hedonic sensory evaluation in the case of bread, the perception of salty taste and responses of preschool children to salt reduction were observed. The combination of quantitative and qualitative data analysis obtained from the case study group, composed of 22 preschool children and 66 teachers and teacher assistants, was studied.
The results show that a 30% salt reduction was not registered by the children, while a 50% reduction of the salt content, compared to the original recipe, though noted, was not disruptive. The perception of taste and development of good eating habits at an early age could be influenced by teachers and teacher assistants' verbal and non-verbal communication.
Salt reduction does not significantly affect the rating of satisfaction with the tested product. Educational personnel must be aware of their decisive influence on children's perception of new and less salty products. Such an approach could represent a basis for creating children's eating habits, which will be of particular importance later in their lives. The findings may possibly result in an update of the national nutrition policy.
The aim of our study was to determine the prevalence of prehypertensive and elevated blood pressure in the hypertensive range (elevated BP) and obtain some anthropometric measures in Slovene children ...and adolescents.
In the cross-sectional study lasting one year, we measured BP using mercury sphygmomanometers, as well as height, weight, waist, and hip circumferences in schools. Data from regular check-ups (oscillometric measurements) were also added to increase the sample size. Participants were 2-19 years old. For statistical analysis, we used two-sided multivariate analysis of variance, Pearson's r, and chi-squared test.
From altogether 1594 participants, 723 (45.4%) were boys and 871 (54.6%) girls. The prevalence of elevated BP on a single oscillometric blood-pressure measurement was 12.0% (95% CI: 10.3 to 13.9), and an additional 13.9% (95% CI: 12.0 to 15.9) had prehypertensive BP. In Riva-Rocci measurements, elevated BP was present in only 7.1% (95% CI: 4.9 to 10.1) and prehypertensive BP additionally in 3.9% (95% CI: 2.4 to 6.4) in comparison to oscillometric measurements, which showed higher prevalence. Importantly, overweight participants had a 1.75 times greater relative risk for prehypertensive BP (95% CI: 1.22 to 2.53; p<0.01). Obesity carried a 1.79 times greater relative risk (95% CI: 1.22 to 2.63; p<0.01) for BP outside of the normotensive BP range.
Arterial hypertension is becoming an important public health problem, especially due to the childhood obesity. It seems to concern also Slovene young population with prevalence of elevated BP at around 7.1% after a single auscultatory BP measurement.
Maščobno tkivo ima vlogo pri številnih endokrinih in presnovnih procesih. Lepin je bil med prvimi odkritimi dejavniki iz maščobnega tkiva, ki delujejo avto-, para- in endokrino. Od opredelitve ...leptina so odkrili še številne druge dejavnike, od katerih se nekateri izločajo iz maščobnih celic, nekateri pa iz drugih celic maščobnega tkiva.
Izhodišča. Namen raziskave je bil analizirati mnenja vzgojiteljev o nastanku poškodbe pri organiziranih in neorganiziranih gibalnih dejavnostih otrok v vrtcih glede na starost otrok. Metode. Podatki ...so bili pridobljeni z anketiranjem 322 vzgojiteljev iz 53 vrtcev v Sloveniji. Izračunane so bile frekvence in izveden hi-kvadrat test. Rezultati. Večina otrok ima v vrtcu organizirane gibalne dejavnosti od 1-krat do 2-krat tedensko; pri otrocih prvega starostnega obdobja trajajo večinoma 20 minut in manj, v drugem starostnem obdobju pa od 20 do 30 minut. Dejavnosti potekajo največkrat v igralnici, v kateri se tudi poškoduje največ otrok. Poškodbe nastanejo najpogosteje pri teku in skokih, manj pri drugih gibalnih dejavnostih. Med prosto igro pa se otroci največkrat poškodujejo na zunanjem igrišču, in to med 9. in 12. uro. Večkrat se poškodujejo dečki kot deklice. Vzgojitelji kot najpogostejši vzrok za poškodbo navajajo nepredvidene situacije, najpogostejše poškodbe pa so udarci, in sicer v glavo, zlasti pri najmlajših otrocih, ki zaradi tega nekaj dni ostanejo doma. Starši najmlajših otrok so tudi manj zadovoljni z ukrepanjem vzgojitelja. Vzgojitelji največkrat sami sanirajo poškodbo in obvestijo starše. Le tretjina vzgojiteljev vedno naredi zapisnik o poškodbi, več kot polovica le pri hujših poškodbah. Zaključki. Analiza je pokazala statistično značilne razlike med različnimi starostnimi skupinami otrok glede vzrokov poškodb, časa nastanka poškodb, prostora, v katerem se otrok poškoduje med organizirano gibalno dejavnostjo, vrste dejavnosti med poškodbami, dela poškodovanega telesa in zadovoljstva staršev z ukrepanjem vzgojitelja ob poškodbi. Na podlagi dobljenih rezultatov so predlagani ukrepi za zmanjševanje poškodb pri predšolskih otrocih v vrtcu.
Navezanost je vedenjski in fiziološki sistem, ki posamezniku omogoča dinamično prilagajanje na okolje. Navezanost se razvija pri sovplivu med dojenčkom in materjo, igra pomembno vlogo pri razvoju ...otrokovih možgan in vpliva na kvaliteto posameznikovih socialnih odnosov vse življenje.
Attachment is a behavioral and physiological system, which enables individual’s dynamic adaptation to its environment. Attachment develops in close interaction between an infant and his/her mother, ...plays an important role in the development of the infant’s brain, and influences the quality of interpersonal relationships throughout life.
Security of attachment is believed to influence individual response to stress, exposing insecurely organized individuals to deregulated autonomic nervous system and exaggerated hypothalamic-pituitary-adrenal activity, which, in turn, produces increased and prolonged exposure to stress-hormones. Such stress responses may have considerable implications for the development of diverse health-risk conditions, such as insulin resistance and hyperlipidemia, shown by numerous studies.
Although the mechanisms are not yet fully understood, there is compelling evidence highlighting the role of psychological stress in the development of type 1 diabetes (T1D). One of the possible contributing factors for the development of T1D may be the influence of attachment security on individual stress reactivity. Thus, the suggestion is that insecurely attached individuals are more prone to experience increased and prolonged influence of stress hormones and other mechanisms causing pancreatic beta-cell destruction. The present paper opens with a short overview of the field of attachment in children, the principal attachment classifications and their historic development, describes the influence of attachment security on individual stress-reactivity and the role of the latter in the development of T1D. Following is a review of recent literature on the attachment in patients with T1D with a conclusion of a proposed role of attachment organization in the etiology of T1D.

Varnost ali oblika navezanosti vpliva na posameznikov odziv na stres (stresno reaktivnost). Tako pride pri negotovo navezanih posameznikih do slabše reguliranega avtonomnega živčnega sistema in pretirane reaktivnosti hipotalamo-hipofizno-suprarenalne osi, zaradi česar so ti v življenju pogosteje in dalj časa izpostavljeni delovanju stresnih hormonov. Tovrsten odziv na stres pa ima pomembno vlogo pri razvoju inzulinske rezistence, hiperlipidemije in drugih stanj, ki predstavljajo tveganje za zdravje.
Čeprav natančni mehanizmi še niso znani, je vedno več dokazov, da psihološki stres pomembno prispeva k razvoju sladkorne bolezni tipa 1 (SBT1). Eden od mehanizmov razvoja te bolezni bi lahko bil tudi vpliv oblike navezanosti na posameznikovo stresno reaktivnost. Tako so lahko negotovo navezani posamezniki pogosteje, dlje in v večji meri izpostavljeni delovanju stresnih hormonov, ki skupaj z drugimi dejavniki povzročajo uničenje beta celic trebušne slinavke.
Ta prispevek prikaže najprej kratek pregled področja navezanosti pri otrocih, glavne oblike navezanosti in njihov zgodovinski razvoj, oriše vpliv oblike navezanosti na posameznikovo stresno reaktivnost in vpliv te reaktivnosti na razvoj SBT1. Zaključi se s predlogom o vlogi oblike navezanosti pri razvoju SBT1 pri otrocih.
Background. Type 1 diabetes (T1D) is an autoimmune chronic disease where hyperglycemia, increased risk of oxidative stress, advanced glycation end-products and other genetic and environmental factors ...lead to T1D complications. Shorter telomeres are associated with hyperglycemic levels and lower serum vitamin D levels.
Methods. Average telomere length (ATL) in whole blood DNA samples was assessed with qPCR method in 53 Slovenian T1D children/adolescents (median age 8.7 years, 1:1.3 male/female ratio). Body mass index standard deviation score (BMI-SDS), glycated haemoglobin and serum level of vitamin D metabolite (25-(OH)-D3) and the age at the onset of T1D were collected from the available medical documentation.
Results. Results indicate shorter ATL in subjects with higher BMI-SDS when compared to those with longer ATL (0.455 ± 0.438, -0.63 ± 0.295; p=0.049). Subjects with higher BMI-SDS had lower serum vitamin D levels when compared to those with lower BMI-SDS (40.66 ± 3.07 vs. 52.86 ± 4.85 nmol/L; p=0.045). Vitamin D serum levels did not significantly differ between subjects with longer/shorter ATL.
Conclusion. T1D children/adolescents with shorter ATL tend to have higher BMI-SDS. Lower serum vitamin D levels were associated with higher BMI-SDS, while associations between vitamin D serum levels, age at the onset of T1D, glycated haemoglobin and ATL were not observed. Additional studies with more participants are required to clarify the role of the telomere dynamics in T1D aetiology and development of complications.
Izhodišče. Sladkorna bolezen tipa 1 (SBT1) je kronična avtoimunska bolezen, pri kateri hiperglikemija ter zvišana raven oksidativnega stresa in končnih produktov glikacije skupaj z genetskimi in okoljskimi dejavniki privedeta do nastanka diabetičnih zapletov. Krajše dolžine telomerov so povezane s hiperglikemičnimi epizodami in nižjimi serumskimi vrednostmi vitamina D.
Metode. Z metodo qPCR smo iz vzorcev DNK periferne krvi določili povprečne dolžine telomerov 53 slovenskim bolnikom s SBT1 (povprečna starost 8,7 leta, razmerje med dečki in deklicami 1:1,3). Indeks standardnega odklona indeksa telesne teže (BMI-SDS), vrednosti serumskega metabolita vitamina D - 25-hidroksikalcifediola (25-(OH)-D3), glikiran hemoglobin in starost preiskovancev ob izbruhu bolezni smo pridobili iz razpoložljive medicinske dokumentacije.
Rezultati. Rezultati nakazujejo krajše dolžine telomerov pri bolnikih z višjimi vrednostmi BMI-SDS (0,455 ± 0,438, -0,63± 0,295; p=0,049). Preiskovanci z višjimi vrednostmi BMI-SDS so imeli nižje vrednosti 25-(OH)-D3 kot preiskovanci z nižjimi vrednostmi BMI-SDS (40,66 ± 3,07 proti 52,86 ± 4,85 nmol/L; p=0,045). Vrednosti 25-(OH)-D3 niso statistično značilno različne pri preiskovancih z višjimi oziroma nižjimi povprečnimi dolžinami telomerov.
Zaključki. Otroci in mladostniki s SBT1 s krajšimi dolžinami telomerov imajo nekoliko višje vrednosti BMI-SDS. Nižje vrednosti 25-(OH)-D3 so povezane z višjim BMI-SDS. Povezav med serumskimi vrednostmi 25-(OH)-D3, starostjo bolnikov ob izbruhu bolezni, glikiranim hemoglobinom in povprečnimi dolžinami telomerov nismo zaznali. Za razjasnitev vloge telomerov v etiologiji, patogenezi in nastanku zapletov SBT1 bodo potrebne nadaljnje raziskave z večjim številom preiskovancev.
Adipose tissue is implicated in many endocrine and metabolic processes. Leptin was among the first identified adipose-secreted factors, which act in an auto-, para- and endocrine manner. Since ...leptin, many other adipose tissue factors were determined, some primarily secreted from the adipocytes, some from other cells of the adipose tissue.
So-called adipokines are not only involved in obesity and its complications, as are insulin resistance, type 2 diabetes and other components of the metabolic syndrome, but also in growth, reproduction, bone metabolism, immune response, cancer development and many other important biological processes. Research in the field of adipokines has revealed new insights into the physiological and pathophysiologal processes and opened new therapeutic possibilities. In the present article, a special emphasis is devoted to research in children and adolescents.
Maščobno tkivo ima vlogo pri številnih endokrinih in presnovnih procesih. Lepin je bil med prvimi odkritimi dejavniki iz maščobnega tkiva, ki delujejo avto-, para- in endokrino. Od opredelitve leptina so odkrili še številne druge dejavnike, od katerih se nekateri izločajo iz maščobnih celic, nekateri pa iz drugih celic maščobnega tkiva.
Tako imenovani adipokini niso povezani le z debelostjo in njenimi zapleti, kot so rezistenca proti inzulinu, sladkorna bolezen tipa 2 in druge komponente metabolnega sindroma, temveč tudi z rastjo, razmnoževanjem, presnovo kosti, imunskim odzivom, razvojem rakavih bolezni in mnogimi drugimi pomembnimi biološkimi procesi. Raziskave na področju adipokinov so opredelile nove fiziološke in patofiziološke procese in odprle nove možnosti zdravljenja. V tem prispevku poseben poudarek namenjamo raziskavam pri otrocih in mladostnikih.
Članek podaja osnovni pregled neformalnega učenja tujih jezikov v Sloveniji, saj je do sedaj objavljenih le malo virov s podatki o tej tematiki, čeprav bi bili pri odločanju o tujejezikovnem ...izobraževanju in jezikovni politiki vsekakor koristni. Pregled ločeno obravnava tri starostne skupine: predšolske otroke, šolsko mladino ter odrasle. Obseg in oblike neformalnega učenja tujih jezikov kot tudi nabor najpogostejših jezikov se med temi skupinami nekoliko razlikujejo. Prispevek črpa iz razpoložljivih podatkov, ki niso enako celostni in zanesljivi kot podatki o formalnem učenju tujih jezikov, vendar nakazujejo nekaj razmisleka vrednih trendov, na primer velik porast učenja tujih jezikov v predšolski in osnovnošolski dobi ter rastoče povpraševanje po nekaterih jezikih, ki so v formalnem izobraževanju zelo redko zastopani.
Type 1 diabetes is a chronic autoimmune disease that affects mainly young people. In the last 50 years, a steady increase of the T1D incidence in the young is reported worldwide, with an average 4 % ...increase annually. In addition, the mean age at the diagnosis is decreasing. Studies show that good metabolic control is important not only for delaying the chronic complications of diabetes but also for improving the quality of life of patients and their families. Continuous education, together with modern technology, is crucial in achieving these goals. Longitudinal data on glycated hemoglobin (HbA1c), along with the data on severe hypoglycemia and severe diabetic ketoacidosis, can describe the quality of care in a defined population. Two national reference diabetes centres taking care of children, adolescents and young adults with diabetes in Israel and Slovenia are described.
Sladkorna bolezen tipa 1 je kronično avtoimuno obolenje, ki najpogosteje prizadene mlade ljudi. Incidenca bolezni zadnjih 50 let narašča po vsem svetu, v povprečju je letni porast incidence ocenjen na 4 %, ob tem pa starost bolnikov ob času diagnoze pada. Raziskave kažejo, da je dobra presnovna urejenost bolnikov s sladkorno boleznijo zelo pomembna, saj je s tem mogoče odložiti pozne zaplete bolezni ter izboljšati kvaliteto življenja bolnikov in njihovih družin. Neprekinjena edukacija bolnikov skupaj z možnostmi moderne tehnologije lahko prispeva k izboljšanju njihove presnovne urejenosti. Presnovno urejenost spremljamo z določanjem glikoziliranega hemoglobina (HbA1c) ter s številom težkih hipoglikemij in ketoacidoz na populacijo pacientov v določenem časovnem obdobju. V prispevku sta opisana dva nacionalna referenčna centra za obravnavo otrok, mladostnikov in mladih odraslih s sladkorno boleznijo v Izraelu in Sloveniji.
