Muscular robusticity and strength in the lower extremities in elite handball players.

The relationship between structural and functional of parameters of skeletal muscles in young athletes needs further observations. The analyses of their age-group differences, sexual dimorphism, asymmetry characteristics in body regions, in sports having different pattern of physical loading could serve important information in this topic. 175 elite Hungarian handball players aged between 14 and 21 years were examined in 2023.

The Oral Microbiome Profile of Water Polo Players Aged 16-20.

Objectives: Chlorine has a strong antibacterial property and is the disinfectant most frequently used in swimming pools. Therefore, the microbiota community in the oral cavity of those who practice water sports is assumed to be special due to their regular immersion in water. Adverse changes in the composition of oral cavity microbiota may have serious health consequences.

Risk and protective factors for health behaviour in adolescence in Europe.

The purpose of the analysis was to identify the risk and protective factors for health behaviour in European adolescents from population health status and expenditure, mental health status, sexual life, social life and education indices and the existence of national strategies, programmes. National and international databases providing information on the presumed health behaviour predictors were used in the analysis. The existence of national health strategies, the level of health expenditure, the socioeconomic conditions, the level of education and literacy had significant influence on the health-risk behaviour of adolescents in the European societies.

A new monitoring system for nutritional status assessment in children at home.

Regular monitoring of children's nutritional status is essential to prevent micronutrient deficiencies, nutritional status abnormalities as stunting, wasting, overweight and obesity. Nutritional status assessment is usually performed by paediatricians by using anthropometry (body mass index, weight to height indices) and/or by body fat-mass measurement (bioimpedance analysis, dual-energy x-ray absorptiometry, computer tomography, etc.).

Urine flow acceleration in healthy children: A retrospective cohort study.

Aims: To establish normal reference values of urine flow acceleration (Q ) in healthy children, as there is a lack of nomograms for normative reference values of Q by voided volumes in the pediatric population so far. Q might be an early indicator of autonomic neuropathy in children and adolescents.

Methods: Data were retrospectively collected from healthy children who underwent uroflowmetry between 1990 and 1992.

INvesTigating the Abnormality of detrusor ConTractility by uroflowmetry in diabetic children (INTACT Trial): protocol of a prospective, observational study.

Introduction: Bladder emptying abnormalities and cardiovascular autonomic dysfunction are manifestations of autonomic dysfunction in people with diabetes mellitus (DM), which are major causes of morbidity and mortality. Since they can reduce the quality of life, they are urgent to be addressed before resulting in complications. As uroflowmetry might determine autonomic neuropathy earlier than cardiovascular autonomic dysfunction symptoms occur, our aim is to detect early abnormalities in bladder muscle function in children with DM.

Effects of regular sport activities on stress level in sporting and non-sporting university students.

Background: Regular sport has favourable influence on the physical and mental state. Our aim was to analyse the relationship between regular sport activities, body parameters, cortisol level, perceived stress and the frequency of psychosomatic symptoms in male and female university students.

Methods: Subjects were university students (N = 200).

Sport Activity Load and Skeletomuscular Robustness in Elite Youth Athletes.

In an earlier report, bone mineral reference values for young athletes were developed. This study addressed variations in bone mineral parameters of young athletes participating in sports with different mechanical loads. The bone mineral status of 1793 male and female athletes, 11 to 20 years of age, in several sports was measured with DEXA.

A proposal for the adjustment of bone mineral density for body dimensions in children.

The precise age estimation is of high importance in bone mineral density (BMD) assessment in children, since the bone structure of a studied child is evaluated by using the age and gender dependent references. In addition, the biological age - the bone age in this case - estimation could help this bone structural evaluation process, since the developmental status of the skeletal system can significantly alter from the theoretical developmental status determined by chronological age in healthy, but early or late maturing children. The aims of the study were (1) to check whether volumetric BMD (vBMD) Z-scores estimated by considering chronological age and biological age differ significantly in children aged between 7-18 years, and (2) in the case of significant inaccuracy of Z-score estimation based on chronological age to construct new vBMD standards adjusted for body developmental status.

Physiological and Psychological Responses to a Maximal Swimming Exercise Test in Adolescent Elite Athletes.

Background: Continuously rising performances in elite adolescent athletes requires increasing training loads. This training overload without professional monitoring, could lead to overtraining in these adolescents.

Methods: 31 elite adolescent athletes (boys: = 19, 16 yrs; girls: = 12, 15 yrs) participated in a field-test which contained a unified warm-up and a 200 m maximal freestyle swimming test.

Body structural and cellular aging of women with low socioeconomic status in Hungary: A pilot study.

Objectives: The health status of an individual is determined not only by their genetic background but also by their physical environment, social environment and access and use of the health care system. The Roma are one of the largest ethnic minority groups in Hungary. The majority of the Roma population live in poor conditions in segregated settlements in Hungary, with most experiencing higher exposure to environmental health hazards.

Bone Mineral Reference Values for Athletes 11 to 20 Years of Age.

Objectives: Training for sport is associated with the development of bone minerals, and the need for reference data based on athletes is often indicated. The purpose of this study was to develop a reference for bone mineral density (BMD) and content (BMC) specific for youth athletes of both sexes participating in several sports. Methods DEXA (dual energy X-ray absorptiometry) was used for total body measurements of bone minerals in 1385 athletes 11 to 20 years, 1019 males and 366 females.

The body composition analysis as a complementary tool in the screening of bone structural abnormalities.

. The importance of early diagnosis, bone-healthy lifestyle and medication is required for remaining fracture free. Dual-energy X-ray absorptiometry and ultrasound densitometry are widely used to screen osteoporosis and other bone structural diseases.

[The prevalence of psychosomatic complaints among 8-17-year-old Hungarian children].

Introduction: Subjective health complaints are common among children as well. Age, gender, health status, etc. can modify the prevalence, intensity, frequency and the dimensions of the psychosomatic complaints.

The association of psychosomatic health with physical status and lifestyle factors in adolescence.

The main purposes were to analyse the age pattern of experiencing psycho-somatic complaints in children; to study the influence of physical status and lifestyle factors on psycho-somatic status. The sample (n: 13,331, aged 7-18) represented a subsample of the 2 Hungarian National Representative Growth Study. Subjects were divided into underweight, normal, preobese and obese subgroups.

Reference data for ultrasound bone characteristics in Hungarian children aged 7-19 years.

Unlabelled: Backround: Osteoporosis is a common disease and physical activity (PA) has a favourable influence on bone status.

Aim: To establish normative data for calcaneal quantitative ultrasound (QUS) bone characteristics in children and to analyse the relationships between PA, anthropometric and bone parameters.

Subjects And Methods: Hungarian children aged 7-19 (n = 2674; 1325 girls, 1349 boys) provided PA, anthropometric and bone data.

The relationship between reproductive and biochemical ageing at the time of the menopausal transition.

The biochemical ageing status of women in the menopausal transition was studied using quantitative analysis of age- and autophagy-related gene activities (CDC42 and MAP1LC3 genes were selected as target genes). Free estradiol and progesterone levels in saliva were estimated. General linear models were used to determine the relationship between lifestyle, health status, socioeconomic factors and CDC42 and MAP1LC3 gene expression levels.

A comparison of skeletal maturity assessed by radiological and ultrasonic methods.

Objectives: The estimation of skeletal maturity is a useful tool in pediatric practice to determine the degree of delay or advancement in growth disorders and the effectiveness of treatment in conditions that influence linear growth. Skeletal maturity of children is commonly assessed using either Greulich-Pyle (GP) or Tanner-Whitehouse methods (TW2 and TW3). However, a less invasive ultrasonic method, that does not use ionizing radiation, has been suggested for use in epidemiological studies of skeletal maturity.

Body fatness and endogenous sex hormones in the menopausal transition.

Background: Age at the final menstrual period is of clinical and public health interest because the age at which natural menopause occurs may be a marker of ageing and health, and in general the menopausal transition increases the risk of many diseases, e.g. redistribution in the pattern of adiposity during the menopausal transition may increase risk of metabolic disease.

Relationship between some indicators of reproductive history, body fatness and the menopausal transition in Hungarian women.

Background: This paper analyzed the relationship between some indicators of reproductive history and body fatness in relation to the timing of the menopause transition in Hungarian women using survival analysis after controlling for birth cohort.

Methods: Data on menstruation and reproductive history were collected during the personal interviews in a sample of 1932 women (aged 35+ years). Menarcheal age, the length of menstrual cycles and menstrual bleedings, regularity of menstrual cycles, number of gestations, lactation, the ever use of contraceptives, menopausal status and age at menopause were used as indicators of reproductive history.

THE BIOLOGICAL STATUS OF CHILDREN LIVING IN DISADVANTAGED REGIONS OF HUNGARY.

The aim of this study was to find out whether differences exist in the physical development, nutritional status and psychosomatic status of children living in deprived regions of Hungary compared with the Hungarian national reference values. The Hungarian government's decree No. 24/2003 created a complex indicator of social and economic conditions by which the country's regions were graded into deprived and non-deprived regions.

SECULAR GROWTH AND MATURATION CHANGES IN HUNGARY IN RELATION TO SOCIOECONOMIC AND DEMOGRAPHIC CHANGES.

This paper analyses the secular changes in the body development patterns of Hungarian children between the 1910s and the beginning of the 2000s in relation to socioeconomic and demographic changes in the country. Individual growth data of children were available from two national growth studies (1983-86, 2003-06), while sample-size weighted means of children's body dimensions were collected through regional studies between the 1920s and 1970s. Gross domestic product, Gini index, life expectancy at birth and under-5 mortality rate were used to assess the changes in economic status, income inequalities of the society and the population's general health status, respectively.

Sexual maturation pattern in the mirror of socioeconomic background.

The inequalities among the socioeconomic strata in the Hungarian society increased during the last decades. Since the socioeconomic conditions play a decisive part in shaping the growth and maturation of children, our purpose was to study the body structure and the growth and maturation pattern of children living in deprived regions in Hungary. Our former analysis revealed that the prevalence of non-normal nutritional status was significantly higher in children and adolescents living in the seriously deprived regions of Hungary than the national reference values.

The relationship between body structure and the socio-economic status in Hungarian children and adolescents.

Among the numerous factors that influence the pattern of children's growth and development there are factors of the changeable socio-economic environment. The inequalities among the socio-economic strata in the Hungarian society have increased during last decades. The main objective of the study was to examine the body structure of children and adolescents living in different socio-economic backgrounds.

Recent trends in childhood obesity and overweight in the transition countries of Eastern and Central Europe.

Objective: Significant political changes--accompanied by economic changes and social restratification--occurred in Eastern and Central European countries in the 1990s. The main purposes of this study were to assess how prevalence of overweight and obese children changed in Hungary during this transitional period; and to compare the prevalence data of childhood overweight in Central and Eastern European countries, where a similar political and socioeconomic environment existed before the transition and similar changes occurred during the transitional period.

Subjects And Methods: Representative samples from the first (1983-1986) and second (2003-2006) Hungarian growth studies were used to assess the prevalence of childhood overweight and obesity in Hungary.
