Long-range repeated-measure sample differences in body dimensions, body composition and physical performance help to describe the changes in a population’s lifestyle. The aim of our study was to analyse such changes in longitudinal studies repeated after a 25-year interval. Data collections repeated every six months for the periods 1977–1981 (n=152) and 2002–2006 (n=158) were carried out in nonathletic boys aged between 6.51 and 11.50 years from the same districts of Budapest. Means for height, body mass, BMI, body fat percentage, and distance covered during a running endurance test, as well as the slopes of the changes were compared. The children of the second series of studies were significantly taller and heavier, had more depot fat and showed poorer cardio-respiratory endurance than their peers 25 years before. The increases with age in weight, BMI and depot fat were steeper in the second series. The significant differences that developed in anthropometric traits and physical performance during these 25 years are regarded as indirect evidence for how severely the average physical condition had declined, as well as how health risks of the schoolchildren had increased.

The aim of the present longitudinal study of four years was to analyse differences in growth patterns, age-related changes in body fat and physical performance in schoolchildren taking part either in normal or in elevated level physical education at school.Nine data collection sessions were carried out between 2002 and 2006 in 18 schools. The sample consisted of 521 non-athletic volunteer boys (PE=116, contrast = 405).The inter-group differences between mean height, body weight, body mass index, relative body fat content, mean scores in 30 m dash, 400 m run, and standing long jump as well as the patterns of change with age were analysed in this comparison. Between-observation differences were tested by repeated measures ANOVA. In case of a significant F-test Tukey’s post-hoc tests were used. Age dependence was also studied by linear regression analysis.The between-group differences in mean height were not significant, but the slope of height increase with age was significantly greater in the PE boys. The PE boys were significantly lighter through all the nine observations and the slope of age-related weight increase was statistically faster in the group of contrast subjects. Both the BMI means and percent body fat means were consistently and significantly greater in the contrast group and faster increases were found in the group of the less active boys. The mean physical performances of the PE boys were consistently and significantly better. Their slopes of increase were statistically different.

Increasing prevalence of overweight and obesity is a serious social and health problem both in the economically developed and developing countries. Despite this fact the nation-wide growth studies completed in Hungary during the past 30 years had not categorised the children either by body fat content or nutritional status. The aim of the study was to estimate the prevalence of overweight and obese boys in the country at the beginning of the new millennium.Height, body mass and four skinfold thicknesses were measured in 7173 volunteer boys aged between 7 and 10 and living in various urban and rural settlements of Hungary between 2003 and 2005. Nutritional status was qualified by the BMI and relative body fat content. The significantly increasing prevalence with age of overweight and obesity ranged between 10.3 and 23.4%. The results showed the joint effects of a secular trend of growth and of a remarkably changed lifestyle. Of these the consequences of the lifestyle are the more important ones. The high and possibly further increasing prevalence of child-age overweight and obesity reminds one of the observations of Kopp and associates (5), namely that of the increased prevalence of chronic childhood diseases during the past 15 years. More intense habitual physical activity and dramatic changes in dietary habits still promise some solution. No one should reckon, however, with the efficiency of physical education at the schools with its very few classes.

This paper examines the effect of breakfast skipping on weight status and abdominal obesity in urban school children. A cross-sectional survey was distributed to all primary schools (n=18) in Óbuda, Budapest. A total of 3714 students (1860 boys, 1854 girls; age range: 7–15 years) were involved. Height, weight and waist circumference (WC) were measured. Data about obesity-related dietary habits (breakfast skipping, fruit and vegetable intake, number of meals, soft drinks consumption) were collected via self-administered questionnaire. One-fifth (21.3%) of the participants were regularly skipping breakfast. Frequency of regular breakfast decreased with age. Breakfast skipping was predictive for higher body mass index (BMI) and WC in a model that was adjusted for age, gender and all studied nutritional factors. Confirming these results, both BMI (19.3±4.0 vs. 18.1±3.7 kg m −2 ; P<0.001) and WC (67.3±12.0 vs. 63.9±10.8 cm; P<0.001) were higher among breakfast skippers than in breakfast eaters. Odds ratios for breakfast skipping for being obese or abdominal obese were 1.59 (95%CI: 1.12–2.26) and 2.04 (95%CI: 1.57–2.65), respectively. Although prospective studies are needed to verify the causality between breakfast skipping and obesity, our findings support the importance of promoting regular breakfast consumption among school children.

Bevezetés: Krónikus obstruktív légúti betegekben a tápanyagok fokozott felhasználása és a szükséglethez képest alacsonyabb energiabevitel miatt alultápláltság alakulhat ki. Célkitűzés: Kutatásunk célja volt felmérni a 40 év feletti, krónikus obstruktív tüdőbetegségben (COPD) szenvedő emberek tápláltsági állapotát, valamint megvizsgáltuk az összefüggéseket a betegség súlyossága és a betegek tápláltsági állapota között. Módszer: Retrospektív obszervációs vizsgálatot végeztünk az Országos Korányi Pulmonológiai Intézet légzésfunkciós laboratóriumában 2017. évben megjelent betegek körében; a légzésfunkciós és antropometriai adatokat az egészségügyi elektronikus nyilvántartási rendszerből nyertük ki. A beválasztási kritériumok a 40 év feletti életkor és a COPD diagnózisa voltak. A légúti obstrukció súlyosságát a mért FEV1-értékek alapján GOLD-stádiumok szerint kategorizáltuk. Eredményeinket SPSS Statistics V22.0 programban dolgoztuk fel. Eredmények: A betegek átlagéletkora 66 év volt; a nemi megosztást tekintve 49,3% férfi és 50,7% nő volt. A COPD-s betegek körében az átlagos testtömegindex (BMI) 27,14 kg/m² volt, értéke széles tartományban mozgott: a cachexia, valamint a súlyos obesitas egyaránt előfordult. A FEV1 (ref%)-értékek alapján a 3236 vizsgált beteget GOLD I.: 30%, GOLD II.: 40%, GOLD III.: 23% és GOLD IV.: 7% stádiumba soroltuk be. Pozitív korrelációt találtunk a mért FEV1-értékek és a tápláltsági állapot között (H = 0,2297, r = 0,1401), azaz a cachexia mértéke a betegség súlyosságával összefüggést mutatott. Varianciaanalízis alapján szignifikáns összefüggést találtunk a betegek tápláltsági állapota és a betegség súlyossága között (p<0,001), azaz a magasabb BMI-vel rendelkező betegek jobb tüdőfunkcióval rendelkeztek. Következtetés: A malnutritio kedvezőtlen hatású a légzésfunkcióra, gyengül a légzőizmok teljesítménye. Vizsgálatunkban a BMI növekedésével a FEV1-értékek javultak, tehát a BMI hasznos mutató lehet a COPD-s betegek légzésfunkciós prognózisának előrejelzésében. Orv Hetil. 2019; 160(23): 908–913.

Bevezetés: COPD-ben szenvedő betegeknél kóros tápláltsági állapot alakulhat ki a gyulladásos citokinek termelődése, valamint a beszűkült étrend miatt. Célkitűzés: A COPD-s betegek tápláltsági állapotának kombinált rizikószűrése, a testtömeg rendellenességének és kapcsolatának vizsgálata a légzőszervi és funkcionális paraméterekkel, valamint e rendellenességek életminőségre gyakorolt hatásának elemzése. Módszer: A tápláltsági rizikó kombinált szűrését végeztük MUST (Malnutrition Universal Screening Tool) kérdőívvel és a bioelektromosimpedancia-analízis elvén működő InBody 170 géppel, valamint OMRON BF511 testösszetétel-elemző mérőkészülékkel az Országos Korányi Pulmonológiai Intézet Légzésrehabilitációs Osztályán 2019. január 1. és december 31. között, 40 év feletti COPD-s betegek körében. Eredmények: A betegek medián életkora 66 (IQR 61–72) év, a medián BMI 24,5 (IQR 19,1–29,7) kg/m² volt; a 110 COPD-s beteg közül 32% (n = 35) alultáplált volt, és 45% (n = 49) akaratlanul fogyott az előző évben. Az alultáplált betegek gyengébb tüdőfunkcióval rendelkeztek (FEV1ref%: 36 [IQR 29–49]), mint a normál súlyú (FEV1ref%: 46 [IQR 35–52]) vagy túlsúllyal rendelkező (FEV1ref%: 46 [IQR 39–57]) betegek, életminőségük szignifikánsan gyengébb volt (65,63 vs. 56,59 vs. 47,23; p = 0,045). Szignifikáns korrelációt találtunk a BMI – FEV1ref% (ρ = 0,26; p = 0,007) és a BMI – exacerbatiók száma között (ρ = 0,37; p = 0,008). Következtetés: Megállapítottuk, hogy az alultáplált COPD-s betegek gyengébb tüdőfunkcióval és rosszabb életminőséggel rendelkeznek, valamint azt is, hogy a kóros tápláltsági állapot kialakulásának magas kockázata miatt COPD-s betegeknél javasoljuk a tápláltsági állapot rizikójának kombinált szűrését és a táplálásterápia hatékonyságának vizsgálatát.

The aim of this comparison was to evaluate the nutritional status and cardio-respiratory fitness of future health professionals, namely university students engaged in medical studies. It was assumed that the lifestyle of such students would be reflected by healthy body composition and fitness performance indicators. Altogether 1,560 volunteer, female, university students of three institutions were investigated in 2008. Height, body weight, BMI, body fat content and 800 m run test means were compared.The height, weight and BMI means did not differ significantly but PE students recorded the lowest mean body fat (18.34% vs. 24.37 and 25.12%) and shortest mean running time (203 s vs. 239 and 243 s). Among the medical (11.23%) and technical university students (19.95%) statistically the same prevalence of obesity was observed.High body fat content and low running performance of medical students were in contrast with our hypothesis. Their prevalence of overweight/obesity and low fitness did not differ from that of relatively sedentary technical university students and the average Hungarian young adult population. Thus, it is questionable how young health professionals will promote the necessity and positive effects of regular physical activity if they do not apply them to their own lifestyle.
